Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies (a) Basis of Presentation The accompanying Consolidated Financial Statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company is not aware of any subsequent event which would require recognition or disclosure. (b) Use of Estimates The preparation of the Consolidated Financial Statements, in conformity with accounting principles generally accepted in the United States of America, requires management to make estimates and judgments that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. On an on-going basis, the Company evaluates its estimates, including, but not limited to, those related to revenue recognition, allowance for doubtful accounts, investments, derivative financial instruments, software development costs, fixed assets, intangible assets, variable compensation, restructuring costs, share-based compensation, income taxes, including the carrying value of deferred tax assets, and litigation and contingencies, including liabilities that the Company deems not probable of assertion. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets, liabilities, and equity that are not readily apparent from other sources. Actual results and outcomes could differ from these estimates and assumptions. (c) Fair Value Measurements The Company measures certain assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that is expected to be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company uses a three-level hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques. The three levels of the fair value hierarchy are described below: Level 1: Quoted (unadjusted) prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2: Inputs other than quoted prices that are either directly or indirectly observable, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3: Inputs that are generally unobservable, supported by little or no market activity, and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The categorization of an asset or liability within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The valuation techniques used by the Company when measuring fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The Company also estimates the fair value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses, accrued compensation and employee benefits, and accrued restructuring costs. The Company considers the carrying value of these instruments in the financial statements to approximate fair value due to their short maturities. (d) Cash and Cash Equivalents and Restricted Cash Cash equivalents include bank demand deposits, money market instruments, certificates of deposit, U.S. Treasury securities, and equivalent funds. The Company generally considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Restricted cash consists of cash balances restricted in use by contractual obligations with third parties. (e) Short-term Investments The Company periodically invests a portion of its excess cash in short-term investment instruments. All highly liquid investments with stated maturity dates between three months and one year from the purchase date are classified as short-term investments. The Company determines the appropriate classification of its short-term investments at the time of purchase. Substantially all of the Company’s short-term investments are in U.S. Treasury securities and certificates of deposit, and the Company has the ability and intent to hold these investments to maturity. Therefore, these short-term investments are classified and accounted for as held-to-maturity and are reported at amortized cost. Each reporting period, the Company determines whether a decline in fair value below the amortized cost for each individual security is other-than-temporary and if it would be required to sell the security before recovery of its amortized cost basis. If an other-than-temporary impairment has occurred, the amount representing the credit loss is recorded in “Other income, net,” and the amount related to all other factors is recognized in “Accumulated other comprehensive income (loss).” Upon recognition of an other-than-temporary impairment, the previous amortized cost basis less the other-than-temporary impairment recognized in earnings becomes the new amortized cost basis of the investment. (f) Derivative Financial Instruments The Company is exposed to certain risks related to its ongoing business operations, including the effect of changes in foreign exchange rates on the Company’s monetary assets and liabilities denominated in foreign currency. The Company may use foreign currency forward contracts as part of its strategy to manage these risks, but does not hold or issue derivative instruments for trading purposes or speculation. The Company executes these instruments with financial institutions that hold an investment grade credit rating. These foreign currency forward contracts do not meet the requirements for hedge accounting and are recorded on the balance sheet as either an asset or liability measured at their fair value as of the reporting date. Changes in the fair value of derivative instruments, as measured using the three-level hierarchy described above, are recognized in “Other income, net” in the Company’s Consolidated Statements of Operations. (g) Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, as follows: three years for computer equipment and purchased software; five years for office equipment and automobiles; and ten years for office furniture and owned corporate aircraft, which has an estimated salvage value of 70%. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the improvements or the term of the lease, whichever is shorter. The Company periodically evaluates the appropriateness of the estimated useful lives and salvage value of all property and equipment. Any change in the estimated useful life or salvage value is treated as a change in estimate and accounted for prospectively in the period of change. Expenditures for maintenance and repairs are charged to expense as incurred, except for certain costs related to the aircraft. The costs of normal, recurring, or periodic repairs and maintenance activities related to the aircraft are expensed as incurred. The cost of planned major maintenance activities (“PMMA”) may be treated differently because those activities may involve the acquisition of additional aircraft components or the replacement of existing aircraft components. PMMA are performed periodically based on passage of time and the use of the aircraft. The classification of a maintenance activity as part of PMMA requires judgment and can affect the amount of expense recognized in any particular period. The cost of each PMMA is expected to be capitalized and amortized over the period until the next scheduled PMMA. There have been no PMMA to date. When assets are retired or sold, the capitalized cost and related accumulated depreciation are removed from the property and equipment accounts and any resulting gain or loss is recognized in the results of operations. Eligible internal-use software development costs are capitalized subsequent to the completion of the preliminary project stage. Such costs include external direct material and service costs, employee payroll, and payroll-related costs. After all substantial testing and deployment is completed and the software is ready for its intended use, capitalization ceases and internal-use software development costs are amortized using the straight-line method over the estimated useful life of the software, generally three years. The Company reviews long-lived assets, including intangible assets, for impairment annually or whenever events or changes in business circumstances indicate that the carrying value of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the undiscounted cash flows to the recorded value of the asset. If an asset is impaired, the asset is written down by the amount by which the carrying value of the asset exceeds the related fair value of the asset. (h) Software Development Costs Software development costs are expensed as incurred until technological feasibility has been established, at which time such costs are capitalized until the product is available for general release to customers. Capitalized software development costs include direct labor costs and fringe benefit costs attributed to programmers, software engineers, and quality control and field certifiers working on products after they reach technological feasibility, but before they are generally available to customers for sale. Technological feasibility is considered to be achieved when a product design and working model of the software product have been completed. Capitalized software development costs are typically amortized over the estimated product life of three years, on a straight-line basis. Recently, the Company has significantly improved the pace of its software development efforts and increased the frequency of its software releases, such that the period between technological feasibility and general release has been significantly reduced, resulting in no software development costs capitalized subsequent to the release of MicroStrategy 10. Capitalized software development costs, net of accumulated amortization, were $8.5 million and $15.9 million as of December 31, 2016 and 2015, respectively. Amortization expense related to software development costs was $7.4 million, $7.2 million, and $5.2 million for the years ended December 31, 2016, 2015, and 2014, respectively, and is included in cost of product licenses and subscription services revenues. During the years ended December 31, 2015 and 2014, the Company capitalized software development costs of $9.6 million and $8.4 million, respectively. The Company did not capitalize any software development costs during the year ended December 31, 2016. The Company analyzes the net realizable value of capitalized software development costs on at least an annual basis and has determined that there is no indication of impairment of the capitalized software development costs as forecasted future sales are adequate to support amortization costs. (i) Restructuring Costs In 2014, the Company committed to, and substantially implemented, a restructuring plan (the “2014 Restructuring Plan”). In connection with the 2014 Restructuring Plan, the Company has incurred restructuring related costs, including employee severance and related benefit costs, contract termination costs, and other related costs. See Note 8, Restructuring, to the Consolidated Financial Statements for further information on the Company’s current restructuring activities. Employee severance and related benefit costs may include cash payments, outplacement services, continuing health insurance coverage, and other benefits. Where no substantive severance or benefit plan relating to the involuntary termination of employees previously exists, these severance costs are generally considered “one-time” benefits and recognized at fair value in the period in which the liability is incurred, which is generally when management has approved and communicated to the terminated employees a detailed plan of termination. Severance costs pursuant to ongoing-benefit arrangements, including statutorily mandated termination benefits or termination benefits provided for in existing employment contracts, are recognized when probable and reasonably estimable. Severance costs are reasonably estimated based on the mix of staffing composition and geography. Where termination benefits are offered for a short period of time in exchange for voluntary termination, severance costs are recognized when the employee has irrevocably accepted the offer. Contract termination costs may include costs to exit office space under existing operating leases and consist of both costs to terminate the contract before the end of the term and costs that will continue to be incurred under the contract for the remaining term without economic benefit to the Company. Costs to terminate the contract before the term has ended are recognized at fair value when the Company terminates the contract in accordance with the contract terms. Costs that will continue to be incurred under the contract for the remaining term without economic benefit to the Company (for example, remaining lease rental payments and executory costs) are recognized at fair value in the period in which the Company ceases using the right conveyed by the contract (for example, when the leased space ceases to be used). In the case of operating leases, these continuing costs are also adjusted for the effects of any prepaid or deferred items previously recognized under the lease and reduced by estimated sublease rental income. Other related costs generally include employee relocation costs, office moving costs, and external consulting and advisory fees related to restructuring activities, including the liquidation of certain foreign subsidiaries. Such costs are recognized at fair value in the period in which the costs are incurred. At each reporting date, the Company evaluates its accrued restructuring costs to determine if the liabilities reported are still appropriate. Any changes to the estimated costs of executing approved restructuring plans are reflected in the Company’s Consolidated Statements of Operations. (j) Loss Contingencies and Legal Costs The Company accrues loss contingencies that are believed to be probable and can be reasonably estimated. As events evolve during the administration and litigation process and additional information becomes known, the Company reassesses its estimates related to loss contingencies. Legal costs are expensed in the period in which the costs are incurred. (k) Deferred Revenue and Advance Payments Deferred revenue and advance payments related to product support, subscription services, and other services result from payments received prior to the performance of services for technical support, subscription, consulting, and education. Deferred revenue and advance payments related to product licenses result primarily from multiple-element arrangements that include future deliverables. Deferred revenue is comprised of deferred product licenses and subscription services, deferred product support, or other services revenue based on the objective fair value of the multiple elements of the arrangement, except for software licenses for which the Company does not have an objective measure of fair value. The Company offsets its accounts receivable and deferred revenue for any billed and unpaid items included in deferred revenue and advance payments. (l) Revenue Recognition The Company recognizes revenue from sales of software licenses to end users upon: 1) persuasive evidence of an arrangement, as provided by agreements, contracts, purchase orders, or other arrangements, generally executed by both parties; 2) existence of a fixed or determinable fee; 3) delivery of the software; and 4) determination that collection is reasonably assured. When the fees for software upgrades and enhancements, technical support, consulting, and education are bundled with the license fee, they are unbundled for revenue recognition purposes, using vendor specific objective evidence (“VSOE”) of fair value of the elements. Product support or post-contract support (“PCS”) revenue is derived from providing technical software support and software updates and upgrades to customers. PCS revenue is recognized ratably over the term of the contract, which in most cases is one year. The Company’s VSOE for PCS, which includes updates, upgrades, and enhancements, is determined based on the optional stated renewal fee for PCS in the contract, which is the price the customer is required to pay when PCS is renewed. Additionally, the optional stated renewal fee used to establish VSOE for PCS in a software transaction must be above the Company’s minimum substantive VSOE rate for PCS. If a stated renewal rate is considered non-substantive, VSOE of PCS has not been established and the Company recognizes all revenue under the arrangement ratably over the PCS period. A minimum substantive VSOE rate is determined based on an analysis of historical sales of PCS. For a renewal rate to be non-substantive, the Company believes it must be significantly lower than its minimum VSOE rate. The Company considers a 10% variance below its minimum VSOE rate to be significant. It is rare for the Company to have an arrangement that includes a renewal rate that is below the minimum VSOE rate. Revenue from consulting, education, and subscription services is recognized as the services are performed. The Company’s VSOE for services other than PCS is determined based on an analysis of its historical sales of each element when sold separately from software. For new offerings of services other than PCS or service offerings that have not had a sufficient history of sales activity, the Company initially establishes VSOE based on the list price as determined by management with the relevant authority. Each service offering has a single list price in each country where sold. If VSOE exists for all undelivered elements and there is no such evidence of fair value established for delivered elements, the arrangement fee is first allocated to the elements where evidence of fair value has been established and the residual amount is allocated to the delivered elements. If evidence of fair value for any undelivered element of an arrangement does not exist, all revenue from the arrangement is deferred until such time that evidence of fair value exists for undelivered elements or until all elements of the arrangement are delivered, subject to certain limited exceptions. If an arrangement includes acceptance criteria, revenue is not recognized until the Company can objectively demonstrate that the software or service can meet the acceptance criteria, or the acceptance period lapses, whichever occurs earlier. If a software license arrangement obligates the Company to deliver specified future products or upgrades, revenue is recognized when the specified future product or upgrades are delivered, or when the obligation to deliver specified future products expires, whichever occurs earlier. If a software license arrangement obligates the Company to deliver unspecified future products, then revenue is recognized on a subscription basis, ratably over the term of the contract. License revenue derived from sales to resellers or original equipment manufacturers who purchase the Company’s products for resale is recognized upon sufficient evidence that the products have been sold to the end user, provided all other revenue recognition criteria have been met. The Company’s standard software license and reseller agreements do not include any return rights other than the right to return non-conforming products for repair or replacement under standard product warranties. During the last three fiscal years, the Company has not experienced any product returns related to warranty claims. The Company generally offers either commercial discounts or referral fees to its channel partners, depending on the nature of services performed. Revenue recognized from transactions with channel partners involved in resale or distribution activities is recorded net of any commercial discounts provided to them. Referral fees paid to channel partners not involved in resale or distribution activities are expensed as cost of revenues and, during the last three fiscal years, were not significant. The Company’s standard software license agreements do not include any price protection provisions. However, transactions under the General Services Administration Federal Supply Schedule contract must comply with the Price Reductions clause. In addition, certain government agencies have the right to cancel contracts for “convenience.” During the last three fiscal years, there were no material amounts refunded under the Price Reductions clause and there were no material contracts cancelled for convenience. Amounts collected prior to satisfying the above revenue recognition criteria are included in net deferred revenue and advance payments in the accompanying Consolidated Balance Sheets. Software revenue recognition requires judgment, including determinations about whether collectability is reasonably assured, the fee is fixed and determinable, a software arrangement includes multiple elements, and if so, whether VSOE exists for those elements. Judgment is also required to assess whether future releases of certain software represent new products or upgrades and enhancements to existing products. The Company also generates subscription services revenues primarily from its cloud services offerings. Subscription services revenues include subscription fees from customers for access to the full breadth of MicroStrategy Analytics and MicroStrategy Mobile capabilities, database services, and data integration services. The Company’s standard arrangements with customers generally do not provide the customer with the right to take possession of the software supporting the cloud-based application service at any time. As such, these arrangements are considered service contracts and revenue is recognized ratably over the service period of the contract, following completion of the set-up service. Any related set-up service fees are recognized ratably over the longer of the contract period or the estimated average life of the customer relationship. The Company’s subscription services are generally offered as standalone arrangements or as part of arrangements that include professional services. If deliverables in a multiple-element arrangement have standalone value upon delivery, the Company accounts for each such deliverable separately. The Company has concluded that its subscription services and its professional services each have standalone value. When the Company enters into multiple-element arrangements that include subscription services and professional services, the total arrangement consideration is allocated to each of the deliverables based on the relative selling price hierarchy. The Company determines the relative selling price for each deliverable using VSOE of selling price, if available, or its best estimate of selling price (“BESP”), if VSOE is not available. The Company has determined that third-party evidence of selling price (“TPE”) is not a practical alternative due to differences in its services offerings as compared to other companies and the lack of availability of third-party pricing information. For professional services, the Company has established VSOE because a consistent number of standalone sales of this deliverable have been priced within a reasonably narrow range. For subscription services, the Company has not established VSOE because, among other factors, the offering is relatively new and its pricing model continues to evolve. Accordingly, the Company uses BESP to determine the relative selling price of its subscription services. The Company determines BESP by reviewing historical transactions and by considering the service’s pricing models and objectives that take into account factors such as gross margin, the size and volume of the transactions, perceived pricing sensitivity, and growth strategies. The determination of BESP is made through consultation with, and approval by, the Company’s management team, taking into consideration the go-to-market strategy. As the Company’s pricing and go-to-market strategies evolve, the Company may modify its pricing practices in the future, which could result in changes to the determination of VSOE and BESP. Amounts, upon invoicing, are recorded in accounts receivable and either gross deferred revenue or revenue, depending on whether the applicable revenue recognition criteria have been met. During 2016, 2015, and 2014, the Company did not generate significant revenues from Usher. (m) Advertising Costs Advertising costs include production costs, which are expensed the first time the advertisement takes place, and media placement costs, which are expensed in the month the advertising appears. Total advertising costs were $1.3 million, $0.5 million, and $3.0 million for the years ended December 31, 2016, 2015, and 2014, respectively. As of December 31, 2016 and 2015, the Company had no prepaid advertising costs. (n) Share-based Compensation The Company maintains its 2013 Stock Incentive Plan (as amended, the “2013 Equity Plan”), under which the Company’s employees, officers, directors, and other eligible participants may be awarded various types of share-based compensation, including options to purchase shares of the Company’s class A common stock. The Company recognizes share-based compensation expense associated with such stock option awards on a straight-line basis over the award’s requisite service period (generally, the vesting period). The share-based compensation expense is based on the fair value of such awards on the date of grant, as estimated using the Black-Scholes option pricing model. See Note 12, Share-based Compensation, to the Consolidated Financial Statements for further information regarding the 2013 Equity Plan, related share-based compensation expense, and assumptions used in the Black-Scholes option pricing model. (o) Income Taxes The Company is subject to federal, state, and local income taxes in the United States and many foreign countries. Deferred income taxes are provided based on enacted tax laws and rates applicable to the periods in which the taxes become payable. For uncertain income tax positions, the Company uses a more-likely-than-not recognition threshold based on the technical merits of the income tax position taken. Income tax positions that meet the more-likely-than-not recognition threshold are measured in order to determine the tax benefit recognized in the financial statements. The Company recognizes accrued interest related to unrecognized tax benefits as part of income tax expense. Penalties, if incurred, are recognized as a component of income tax expense. The Company provides a valuation allowance to reduce deferred tax assets to their estimated realizable value, when appropriate. (p) Basic and Diluted Earnings Per Share Basic earnings per share is determined by dividing the net income attributable to common stockholders by the weighted average number of common shares and participating securities outstanding during the period. Participating securities are included in the basic earnings per share calculation when dilutive. Diluted earnings per share is determined by dividing the net income attributable to common stockholders by the weighted average number of common shares and potential common shares outstanding during the period. Potential common shares are included in the diluted earnings per share calculation when dilutive. Potential common shares consisting of common stock issuable upon exercise of outstanding employee stock options and warrants are computed using the treasury stock method. Potential common shares also consist of common stock issuable upon the conversion of preferred stock. The Company has two classes of common stock: class A common stock and class B common stock. Holders of class A common stock generally have the same rights, including rights to dividends, as holders of class B common stock, except that holders of class A common stock have one vote per share while holders of class B common stock have ten votes per share. Each share of class B common stock is convertible at any time, at the option of the holder, into one share of class A common stock. As such, basic and fully diluted earnings per share for class A and class B common stock are the same. The Company has never declared or paid any cash dividends on either class A or class B common stock. As of December 31, 2016 and 2015, there were no shares of preferred stock outstanding. (q) Foreign Currency Translation The functional currency of the Company’s international operations is the local currency. Accordingly, all assets and liabilities of international subsidiaries are translated using exchange rates in effect at the end of the period, and revenue and expenses are translated using weighted average exchange rates for the period. The related translation adjustments are reported in “Accumulated other comprehensive income (loss)” in stockholders’ equity. In general, upon complete or substantially complete liquidation of an investment in an international subsidiary, the amount of accumulated translation adjustments attributable to that subsidiary is reclassified from stockholders’ equity to the statement of operations. Transaction gains and losses arising from transactions denominated in a currency other than the functional currency of the entity involved are included in the results of operations. In 2015, as a result of the completion of the liquidation of one of the Company’s foreign subsidiaries as part of the 2014 Restructuring Plan, a $0.3 million foreign currency translation gain was reclassified from “Accumulated other comprehensive loss” in the accompanying Consolidated Balance Sheets to “Other income, net” in the accompanying Consolidated Statements of Operations. No reclassifications were recorded in 2016 or 2014. As of December 31, 2016, 2015, and 2014, the cumulative foreign currency translation balances were $(10.8) million, $(7.4) million, and $(4.4) million, respectively. Since the Company intends to indefinitely reinvest its undistributed earnings of all of its subsidiaries, no taxes were recognized on the temporary differences resulting from foreign currency translation adjustments for the years ended December 31, 2016, 2015, and 2014. Transaction gains and losses arising from transactions denominated in foreign currencies resulted in net gains of $3.0, $2.4, and $5.3 million in 2016, 2015, and 2014, respectively, and are included in “Other income, net” in the accompanying Consolidated Statements of Operations. (r) Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, short-term investments, foreign currency forward contracts, and accounts receivable. The Company places its cash equivalents and enters into foreign currency forward contracts with high credit-quality financial institutions and invests its excess cash primarily in short-term investments. The Company has established guidelines relative to credit ratings and maturities that seek to maintain safety and liquidity. The Company sells products and services to various companies across several industries throughout the world in the ordinary course of business. The Company routinely assesses the financial strength of its customers and maintains allowances for anticipated losses. As of December 31, 2016 and 2015, no individual customer accounted for 10% or more of net accounts receivable, and for the years ended December 31, 2016, 2015, and 2014, no individual customer accounted for 10% or more of revenue.

Fair Value Disclosures [Abstract]
Fair Value Measurements	(4) Fair Value Measurements As of December 31, 2016 and 2015, there were no financial assets or liabilities measured at fair value on a recurring basis. The fair value of the Company’s foreign currency forward contracts is determined using Level 2 observable market inputs to extrapolate forward points to be added to or subtracted from the closing market spot rate on the reporting date, and then discounted to present value. Changes in the fair value of the Company’s foreign currency forward contracts during 2016, 2015, and 2014 were as follows (in thousands): Years Ended December 31, Location 2016 2015 2014 Non-hedging derivative instruments: Unrealized (loss) gain on foreign currency forward contracts Other $ 0 $ (1,641 ) $ 1,682 Realized gain (loss) on foreign currency forward contracts Other income, net $ 0 $ 2,129 $ (562 ) The “Unrealized (loss) gain on foreign currency forward contracts” line item in the above table includes both the unrealized fair value gains and losses on outstanding foreign currency forward contracts and the reversal of previous period unrealized gains and losses upon the settlement of foreign currency forward contracts. There were no foreign currency forward contracts outstanding as of December 31, 2016. There were no transfers among the levels within the fair value hierarchy during the years ended December 31, 2016, 2015, and 2014. As of December 31, 2016 and 2015, the Company had no assets or liabilities that were required to be measured at fair value on a non-recurring basis.

Short Term Investments Abstract
Short-term Investments	(5) Short-term Investments The Company periodically invests a portion of its excess cash in short-term investment instruments. Substantially all of the Company’s short-term investments are in U.S. Treasury securities and certificates of deposit, and the Company has the ability and intent to hold these investments to maturity. The stated maturity dates of these investments are between three months and one year from the purchase date. These held-to-maturity investments are recorded at amortized cost and included within “Short-term investments” on the accompanying Consolidated Balance Sheets. The fair value of held-to-maturity investments in U.S. Treasury securities and certificates of deposit is determined based on quoted market prices in active markets for identical securities (Level 1 inputs). The amortized cost, carrying value, and fair value of held-to-maturity investments at December 31, 2016 were $187.3 million, $187.3 million, and $187.3 million, respectively. The amortized cost, carrying value, and fair value of held-to-maturity investments at December 31, 2015 were $193.3 million, $193.3 million, and $193.2 million, respectively. The gross unrecognized holding gains and losses were not material for 2016, 2015, and 2014. No other-than-temporary impairments related to these investments have been recognized as of December 31, 2016 and 2015. As of December 31, 2016 and 2015, the Company’s available-for-sale investments were not material.

The Company maintains an allowance for doubtful accounts which represents its best estimate of probable losses inherent in the accounts receivable balances. The Company evaluates specific accounts when it becomes aware that a customer may not be able to meet its financial obligations due to deterioration of its liquidity or financial viability, credit ratings, or bankruptcy. In addition, the Company periodically adjusts this allowance based on its review and assessment of the aging of receivables.

Restructuring And Related Activities [Abstract]
Restructuring	(8) Restructuring In September 2014, the Company committed to the 2014 Restructuring Plan to streamline its workforce and spending to better align its cost structure with its business strategy, including reducing the Company’s workforce by 777 employees, comprised of 217 employees in North America, 400 employees in Asia Pacific, 141 employees in Europe, the Middle East, and Africa, and 19 employees in Latin America. The Company implemented substantially all of the 2014 Restructuring Plan by the end of 2014. The Company does not expect any future costs associated with the 2014 Restructuring Plan. Costs associated with the 2014 Restructuring Plan include employee severance and related benefit costs (including outplacement services and continuing health insurance coverage), contract termination costs (including operating lease terminations for certain office space at the Company’s corporate headquarters and other international locations), and other charges (including external consulting and advisory fees related to implementing the 2014 Restructuring Plan). The following table summarizes the major types of costs associated with the 2014 Restructuring Plan (in thousands) for the years ended December 31, 2016, 2015 and 2014, total costs incurred through December 31, 2016, and total costs expected: Years Ended December 31, Cumulative Costs Total Expected 2016 2015 2014 Incurred To Date Plan Costs Severance and related employee benefits $ 0 $ 0 $ 13,162 $ 13,162 $ 13,162 Contract termination costs 0 0 1,159 1,159 1,159 Other costs 45 279 411 735 735 Total restructuring costs $ 45 $ 279 $ 14,732 $ 15,056 $ 15,056 The total restructuring costs above are reported as “Restructuring costs” under “Operating expenses” in the Company’s Consolidated Statements of Operations.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	(10) Commitments and Contingencies (a) Commitments From time to time, the Company enters into certain types of contracts that require it to indemnify parties against third-party claims. These contracts primarily relate to agreements under which the Company assumes indemnity obligations for intellectual property infringement, as well as other obligations from time to time depending on arrangements negotiated with customers and other third parties. The conditions of these obligations vary. Thus, the overall maximum amount of the Company’s indemnification obligations cannot be reasonably estimated. Historically, the Company has not been obligated to make significant payments for these obligations and does not currently expect to incur any material obligations in the future. Accordingly, the Company has not recorded an indemnification liability on its balance sheets as of December 31, 2016 or December 31, 2015. The Company leases office space and computer and other equipment under operating lease agreements. It also leases certain computer and other equipment under capital lease agreements and licenses certain software under other financing arrangements. Under the lease agreements, in addition to base rent, the Company is generally responsible for certain taxes, utilities and maintenance costs, and other fees; and several leases include options for renewal or purchase. The Company leases approximately 214,000 square feet of office space at a location in Northern Virginia that began serving as its corporate headquarters in October 2010. The term of the lease expires in December 2020. At December 31, 2016 and 2015, deferred rent of $12.3 million and $15.7 million, respectively, was included in other long-term liabilities and $3.5 million and $3.3 million, respectively, was included in current accrued expenses. The following table shows future minimum rent payments under noncancellable operating and capital leases and agreements with initial terms of greater than one year, net of total future minimum rent payments to be received under noncancellable sublease agreements (in thousands), based on the expected due dates of the various installments as of December 31, 2016: Capital Leases Operating Leases and Other Financing Year Amount Amount 2017 $ 20,461 $ 1,101 2018 19,608 1,101 2019 18,245 0 2020 18,103 0 2021 2,100 0 Thereafter 5,807 0 $ 84,324 $ 2,202 Total rental expenses under operating lease agreements for the years ended December 31, 2016, 2015, and 2014 were $20.3 million, $22.6 million, and $30.4 million, respectively. (b) Contingencies In December 2011, DataTern, Inc. (“DataTern”) filed a complaint for patent infringement against the Company in the United States District Court for the District of Massachusetts (the “District Court”). The complaint alleged that the Company infringes U.S. Patent No. 6,101,502 (the “’502 Patent”), allegedly owned by DataTern, by making, selling, or offering for sale several of the Company’s products and services including MicroStrategy 9, MicroStrategy Intelligence Server, MicroStrategy Business Intelligence Platform, MicroStrategy Cloud Personal, and other MicroStrategy applications for creating or using data mining, dashboards, business analytics, data storage and warehousing, and Web hosting support. The complaint accused the Company of willful infringement and sought an unspecified amount of damages, an award of attorneys’ fees, and preliminary and permanent injunctive relief. In light of a judgment in a separate action involving DataTern in another jurisdiction, in February 2013, MicroStrategy and DataTern filed motions for summary judgment of non-infringement and the District Court entered summary judgment against DataTern. In March 2013, DataTern filed a notice of appeal with the United States Court of Appeals for the Federal Circuit (the “Federal Circuit”). In December 2014, the Federal Circuit issued an opinion vacating the District Court’s summary judgment, stating that the claim construction on which the summary judgment was based was incorrect. In January 2015, the case was remanded to the District Court for further proceedings. A claim construction ruling was issued in February 2017. The Company has received indemnification requests from certain of its channel partners and customers who were sued by DataTern in the District Court in lawsuits alleging infringement of the ‘502 Patent. The proceedings against these channel partners and customers have been stayed pending the resolution of DataTern’s lawsuit against the Company. The outcome of these matters is not presently determinable, and the Company cannot make a reasonable estimate of the possible loss or range of loss with respect to these matters at this time. Accordingly, no estimated liability for these matters has been accrued in the accompanying Consolidated Financial Statements. The Company is also involved in various other legal proceedings arising in the normal course of business. Although the outcomes of these other legal proceedings are inherently difficult to predict, management does not expect the resolution of these other legal proceedings to have a material adverse effect on the Company’s financial position, results of operations, or cash flows. The Company has contingent liabilities that, in management’s judgment, are not probable of assertion. If such unasserted contingent liabilities were to be asserted, or become probable of assertion, the Company may be required to record significant expenses and liabilities in the period in which these liabilities are asserted or become probable of assertion.

Income Taxes	(11) Income Taxes U.S. and international components of income (loss) before income taxes (in thousands) were comprised of the following for the periods indicated: Years Ended December 31, 2016 2015 2014 U.S. $ 51,145 $ 68,555 $ (5,389 ) Foreign 61,901 69,309 16,440 Total $ 113,046 $ 137,864 $ 11,051 The provision for income taxes (in thousands) consisted of the following for the periods indicated: Years Ended December 31, 2016 2015 2014 Current: Federal $ 18,453 $ 11,748 $ (306 ) State 3,681 2,997 (1 ) Foreign 4,941 7,565 7,638 $ 27,075 $ 22,310 $ 7,331 Deferred: Federal $ (4,742 ) $ 9,215 $ (2,132 ) State (890 ) 693 (1,038 ) Foreign 695 (285 ) 1,855 $ (4,937 ) $ 9,623 $ (1,315 ) Total provision $ 22,138 $ 31,933 $ 6,016 The provision for income taxes differs from the amount computed by applying the federal statutory income tax rate to the Company’s income before income taxes as follows for the periods indicated: Years Ended December 31, 2016 2015 2014 Income tax expense at federal statutory rate 35.0 % 35.0 % 35.0 % State taxes, net of federal tax effect 1.6 % 1.7 % -4.3 % Foreign earnings taxed at different rates -15.5 % -14.0 % 2.9 % Withholding tax 1.4 % 1.1 % 14.3 % Foreign tax credit -1.0 % -0.3 % -9.6 % Other international components -0.1 % 0.8 % 0.8 % Change in valuation allowance -0.8 % -0.1 % 21.1 % Deferred tax adjustments and rate changes 0.1 % -0.1 % -4.9 % Meals and entertainment 0.4 % 0.3 % 5.9 % Non-deductible officers compensation 0.1 % 0.0 % 2.0 % Personal use of corporate aircraft 0.1 % 0.1 % 2.5 % Subpart F income 0.6 % 0.5 % 4.0 % Research and development tax credit -0.8 % -0.6 % -13.7 % Section 199 Deduction -1.8 % -1.5 % 0.0 % Other permanent differences 0.3 % 0.3 % -1.6 % Total 19.6 % 23.2 % 54.4 % The Company’s U.S. and foreign effective tax rates for income before income taxes were as follows for the periods indicated: Years Ended December 31, 2016 2015 2014 U.S. 32.3 % 36.0 % 64.5 % Foreign 9.1 % 10.5 % 57.7 % Combined 19.6 % 23.2 % 54.4 % Except as discussed below, the Company intends to indefinitely reinvest its undistributed earnings of all of its foreign subsidiaries. Therefore, the annualized effective tax rate applied to the Company’s pre-tax income does not include any provision for U.S. federal and state income taxes on the amount of the undistributed foreign earnings. U.S. federal tax laws, however, require the Company to include in its U.S. taxable income certain investment income earned outside of the United States in excess of certain limits (“Subpart F deemed dividends”). Because Subpart F deemed dividends are already required to be recognized in the Company’s U.S. federal income tax return, the Company regularly repatriates Subpart F deemed dividends to the United States and no additional tax is incurred on the distribution. The Company repatriated Subpart F deemed dividends of $1.9 million and $1.3 million in 2016 and 2014, respectively, with no additional tax incurred. The Company did not repatriate any Subpart F deemed dividends in 2015 because it did not report any Subpart F income on its 2014 U.S. tax return. As of December 31, 2016 and 2015, the amount of cash and cash equivalents and short-term investments held by U.S. entities was $279.8 million and $219.3 million, respectively, and by non-U.S. entities was $309.6 million and $266.4 million, respectively. If the cash and cash equivalents and short-term investments held by non-U.S. entities were to be repatriated to the United States, the Company would generate U.S. taxable income to the extent of the Company’s undistributed foreign earnings, which amounted to $322.0 million at December 31, 2016. Although the tax impact of repatriating these earnings is difficult to determine, the Company would not expect the maximum effective tax rate that would be applicable to such repatriation to exceed the U.S. statutory rate of 35.0%, after considering applicable foreign tax credits. Deferred income taxes reflect the net tax effects of the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities (in thousands) were as follows for the periods indicated: December 31, 2016 2015 Deferred tax assets, net: Net operating loss carryforwards $ 214 $ 501 Tax credits 1,372 2,984 Intangible assets 11 24 Deferred revenue adjustment 3,305 3,454 Accrued compensation 7,866 7,331 Share-based compensation expense 11,440 9,905 Deferred rent 1,281 2,409 Other 2,002 2,915 Deferred tax assets before valuation allowance 27,491 29,523 Valuation allowance (832 ) (1,984 ) Deferred tax assets, net of valuation allowance 26,659 27,539 Deferred tax liabilities: Prepaid expenses and other 1,098 1,389 Property and equipment 10,821 12,253 Capitalized software development costs 3,330 5,925 Total deferred tax liabilities 15,249 19,567 Total net deferred tax asset $ 11,410 $ 7,972 Reported as: Non-current deferred tax assets, net 11,704 7,989 Non-current deferred tax liabilities (294 ) (17 ) Total net deferred tax asset $ 11,410 $ 7,972 As of December 31, 2016 and 2015, the Company had income taxes payable of $10.5 million and $4.8 million, respectively, recorded in “Accounts payable and accrued expenses” in the Company’s Consolidated Balance Sheets. As of December 31, 2016, the Company had unrecognized tax benefits of $3.5 million, recorded in “Other long-term liabilities” in the Company’s Consolidated Balance Sheets. The change in unrecognized tax benefits (in thousands) is presented in the table below: Unrecognized tax benefits at January 1, 2016 $ 3,298 Increase related to positions taken in prior period 76 Increase related to positions taken in current period 241 Decrease related to expiration of statute of limitations (100 ) Decrease related to settlement with tax authority (394 ) Unrecognized tax benefits at December 31, 2016 3,121 Accrued interest 415 Unrecognized tax benefits recorded in other long-term liabilities at December 31, 2016 $ 3,536 If recognized, $2.8 million of the gross unrecognized tax benefits would impact the Company’s effective tax rate. Over the next 12 months, the amount of the Company’s liability for unrecognized tax benefits shown above is not expected to change by a material amount. The Company recognizes estimated accrued interest related to unrecognized tax benefits in the provision for income tax accounts. During the year ended December 31, 2016, 2015 and 2014, the Company released or recognized an immaterial amount of accrued interest. The amount of accrued interest related to the above unrecognized tax benefits was approximately $0.4 million and $0.3 million as of December 31, 2016 and 2015, respectively. The Company files tax returns in numerous foreign countries as well as the United States and its tax returns may be subject to audit by tax authorities in all countries in which it files. Each country has its own statute of limitations for making assessment of additional tax liabilities. In 2016, the Company settled the tax examination in the United States for tax years 2011 and 2012 without any material audit assessments. The Company’s U.S. tax returns for tax years from 2013 forward are subject to potential examination by the Internal Revenue Service. The Company’s major foreign tax jurisdictions and the tax years that remain subject to potential examination are Germany for tax years 2013 forward, Poland and China for tax years 2012 forward, Spain for tax years 2013 forward, and the United Kingdom for tax years 2015 forward. To date there have been no material audit assessments related to audits in the United States or any of the applicable foreign jurisdictions. The Company had no U.S. net operating loss carryforwards as of December 31, 2016 and 2015. The Company had $0.7 million and $1.1 million of foreign net operating loss carryforwards as of December 31, 2016 and 2015, respectively. The Company had foreign tax credit and certain state tax credit carryforward tax assets totaling $0.3 million at December 31, 2016, which begin to expire in 2026. The Company had domestic research and development tax credit, foreign tax credit, and alternative minimum tax credit carryforward tax assets totaling $1.8 million at December 31, 2015. The timing and ability of the Company to use these losses and credits may be limited by Internal Revenue Code provisions regarding changes in ownership of the Company as discussed below. The Company’s valuation allowances of $0.8 million and $2.0 million at December 31, 2016 and 2015, respectively, primarily relate to certain foreign tax credit carryforward tax assets. In determining the Company’s provision for or benefit from income taxes, net deferred tax assets, liabilities, and valuation allowances, management is required to make judgments and estimates related to projections of domestic and foreign profitability, the timing and extent of the utilization of net operating loss carryforwards, applicable tax rates, transfer pricing methods, and prudent and feasible tax planning strategies. As a multinational company, the Company is required to calculate and provide for estimated income tax liabilities for each of the tax jurisdictions in which it operates. This process involves estimating current tax obligations and exposures in each jurisdiction, as well as making judgments regarding the future recoverability of deferred tax assets. Changes in the estimated level of annual pre-tax income, changes in tax laws, particularly changes related to the utilization of net operating losses in various jurisdictions, and changes resulting from tax audits can all affect the overall effective income tax rate which, in turn, impacts the overall level of income tax expense or benefit and net income. Judgments and estimates related to the Company’s projections and assumptions are inherently uncertain. Therefore, actual results could differ materially from projections. The timing and manner in which the Company will use research and development tax credit carryforward tax assets, alternative minimum tax credit carryforward tax assets, and foreign tax credit carryforward tax assets in any year, or in total, may be limited by provisions of the Internal Revenue Code regarding changes in the Company’s ownership. Currently, the Company expects to use the tax assets, subject to Internal Revenue Code limitations, within the carryforward periods. Valuation allowances have been established where the Company has concluded that it is more likely than not that such deferred tax assets are not realizable. If the Company is unable to sustain profitability in future periods, it may be required to increase the valuation allowance against the deferred tax assets, which could result in a charge that would materially adversely affect net income in the period in which the charge is incurred. Section 382 of the Internal Revenue Code provides an annual limitation on the amount of federal net operating losses and tax credits that may be used in the event of an ownership change. The limitation is based on, among other things, the value of the company as of the change date multiplied by a U.S. federal long-term tax exempt interest rate. The Company does not currently expect the limitations under the Section 382 ownership change rules to impact the Company’s ability to use its net operating loss carryforwards or tax credits that existed as of the date of the ownership change.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Share-based Compensation	(12) Share-based Compensation The 2013 Equity Plan authorizes the issuance of various types of share-based awards to the Company’s employees, officers, directors, and other eligible participants. As of December 31, 2016, the total number of shares of the Company’s class A common stock authorized for issuance under the 2013 Equity Plan was 1,700,000 shares. During 2016, stock options to purchase an aggregate of 45,000 shares of class A common stock were granted to certain Company employees and directors pursuant to the 2013 Equity Plan. As of December 31, 2016, there were options to purchase 885,833 shares of class A common stock outstanding under the 2013 Equity Plan. As of December 31, 2016, there were 602,500 remaining shares of class A common stock authorized for future issuance under the 2013 Equity Plan. Shares issued under the 2013 Equity Plan may consist in whole or in part of authorized but unissued shares or treasury shares. No awards may be issued more than ten years after the 2013 Equity Plan’s effective date. Stock options that are granted under the 2013 Equity Plan must have an exercise price equal to at least the fair market value of the Company’s class A common stock on the date of grant, become exercisable as established by the Board of Directors or the Compensation Committee, and expire no later than ten years following the date of grant. The Company recognizes share-based compensation expense associated with such stock option awards on a straight-line basis over the award’s requisite service period (generally, the vesting period). The stock option awards granted to date vest in equal annual installments over an approximately four-year vesting period (unless accelerated upon a change in control event (as defined in the stock option agreement for the applicable award) or otherwise in accordance with provisions of the 2013 Equity Plan or applicable option agreement). Share-based compensation expense is based on the fair value of the stock option awards on the date of grant, as estimated using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires the input of certain management assumptions, including the expected term, expected stock price volatility, risk-free interest rate, and expected dividend yield. The Company estimates the term over which option holders are expected to hold their stock options by using the simplified method for “plain-vanilla” stock option awards because the Company’s stock option exercise history does not provide a reasonable basis to compute the expected term for stock options granted under the 2013 Equity Plan. The Company relies exclusively on its historical stock price volatility to estimate the expected stock price volatility over the expected term because the Company believes future volatility is unlikely to differ from the past. In estimating the expected stock price volatility, the Company uses a simple average calculation method. The risk-free interest rate is based on U.S. Treasury securities with terms that approximate the expected term of the stock options. The expected dividend yield is based on the Company’s past cash dividend history and anticipated future cash dividend payments. The expected dividend yield is zero, as the Company has not previously declared cash dividends and does not currently intend to declare cash dividends in the foreseeable future. These assumptions are based on management’s best judgment, and changes to these assumptions could materially affect the fair value estimates and amount of share-based compensation expense recognized. The following table summarizes the Company’s stock option activity (in thousands, except per share data and years) for the periods indicated: Stock Options Outstanding Weighted Average Aggregate Weighted Average Exercise Price Intrinsic Remaining Contractual Shares Per Share Value Term (Years) Balance as of January 1, 2014 600 $ 92.84 Granted 745 125.46 Exercised (9 ) 92.84 $ 653 Forfeited/Expired (135 ) 104.48 Balance as of December 31, 2014 1,201 $ 111.77 Granted 380 178.93 Exercised (91 ) 105.25 $ 6,367 Forfeited/Expired (167 ) 131.31 Balance as of December 31, 2015 1,323 $ 129.04 Granted 45 189.62 Exercised (112 ) 97.82 $ 8,102 Forfeited/Expired (370 ) 110.28 Balance as of December 31, 2016 886 $ 143.89 Exercisable as of December 31, 2016 345 $ 135.25 $ 21,520 7.6 Expected to vest as of December 31, 2016 541 $ 149.39 26,303 7.9 Total 886 $ 143.89 $ 47,823 7.7 Stock options outstanding as of December 31, 2016 are comprised of the following range of exercise prices per share (in thousands, except per share data and years): Stock Options Outstanding at December 31, 2016 Weighted Average Weighted Average Exercise Price Remaining Contractual Range of Exercise Prices per Share Shares Per Share Term (Years) $117.85 - $120.00 30 $ 118.63 7.3 $120.01 - $150.00 510 $ 121.43 7.3 $150.01 - $180.00 216 $ 167.21 8.2 $180.01 - $201.25 130 $ 198.99 8.8 Total 886 $ 143.89 7.7 An aggregate of 222,500, 283,750, and 150,000 stock options with an aggregate fair value of $13.7 million, $14.2 million, and $6.3 million vested during the years ended December 31, 2016, 2015, and 2014, respectively. The Company expects all unvested and outstanding options at December 31, 2016 to fully vest in future years in accordance with their vesting schedules. Therefore, share-based compensation expense has not been adjusted for any expected forfeitures. The weighted average grant date fair value of stock option awards using the Black-Scholes option pricing model was $75.54, $73.86, and $55.84 for each share subject to a stock option granted during the years ended December 31, 2016, 2015, and 2014, respectively, based on the following assumptions: Years Ended December 31, 2016 2015 2014 Expected term of options in years 6.3 6.3 6.3 Expected volatility 38.5% 39.0% - 40.2% 41.5% - 42.5% Risk-free interest rate 1.4% - 1.6% 1.5% - 2.0% 2.1% - 2.3% Expected dividend yield 0.0% 0.0% 0.0% The Company recognized approximately $11.8 million, $17.3 million, and $11.8 million in share-based compensation expense for the years ended December 31, 2016, 2015, and 2014, respectively, from stock options granted under the 2013 Equity Plan. As of December 31, 2016, there was approximately $25.7 million of total unrecognized share-based compensation expense related to unvested stock options. As of December 31, 2016, the Company expected to recognize this remaining share-based compensation expense over a weighted-average vesting period of approximately 2.0 years. During the years ended December 31, 2016 and 2015, the Company was able to recognize and utilize net operating loss carryforwards arising directly from tax deductions related to equity compensation in excess of compensation recognized for financial reporting that was generated in the current and/or prior year under the 2013 Equity Plan. Accordingly, stockholders’ equity increased by $1.2 million and $1.1 million during the years ended December 31, 2016 and 2015, respectively. No windfall tax benefit was realized from the exercise of stock options during the year ended December 31, 2014. During the year ended December 31, 2016, the Company wrote off $1.7 million of deferred tax assets related to certain vested stock options that were no longer exercisable. Accordingly, additional paid-in capital decreased by $1.7 million during the year ended December 31, 2016. No such adjustment was made during the years ended December 31, 2015 and 2014. During the year ended December 31, 2016, the Company paid $3.7 million to tax authorities related to the net exercise of a stock option under the 2013 Equity Plan. This payment resulted in a $3.7 million reduction to additional paid-in capital during the year ended December 31, 2016. No net exercises of stock options were made during the years ended December 31, 2015 and 2014.

Equity [Abstract]
Treasury Stock	(14) Treasury Stock The Board of Directors has authorized the Company’s repurchase of up to an aggregate of $800.0 million of its class A common stock from time to time on the open market through April 29, 2018 (the “2005 Share Repurchase Program”), although the program may be suspended or discontinued by the Company at any time. The timing and amount of any shares repurchased will be determined by the Company’s management based on its evaluation of market conditions and other factors. The 2005 Share Repurchase Program may be funded using the Company’s working capital, as well as proceeds from any other funding arrangements that the Company may enter into in the future. As of December 31, 2016, the Company had repurchased an aggregate of 3,826,947 shares of its class A common stock at an average price per share of $90.23 and an aggregate cost of $345.3 million pursuant to the 2005 Share Repurchase Program. The average price per share and aggregate cost amounts disclosed above include broker commissions. During the years ended December 31, 2016, 2015, and 2014, the Company did not repurchase any shares of its class A common stock pursuant to the 2005 Share Repurchase Program.

Selected Quarterly Financial Data (Unaudited)	(17) Selected Quarterly Financial Data (Unaudited) The following tables contain unaudited Statement of Operations information for each quarter of 2016 and 2015. The Company believes that the following information reflects all normal recurring adjustments. During the fourth quarter of 2016, the Company reversed the accrual for potential future payments in connection with the departure from the Company of two executives in connection with an executive management reorganization in January 2016, which resulted in a $3.4 million increase in net income. The operating results for any quarter are not necessarily indicative of results for any future period.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Basis of Presentation	(a) Basis of Presentation The accompanying Consolidated Financial Statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company is not aware of any subsequent event which would require recognition or disclosure.
Use of Estimates	(b) Use of Estimates The preparation of the Consolidated Financial Statements, in conformity with accounting principles generally accepted in the United States of America, requires management to make estimates and judgments that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. On an on-going basis, the Company evaluates its estimates, including, but not limited to, those related to revenue recognition, allowance for doubtful accounts, investments, derivative financial instruments, software development costs, fixed assets, intangible assets, variable compensation, restructuring costs, share-based compensation, income taxes, including the carrying value of deferred tax assets, and litigation and contingencies, including liabilities that the Company deems not probable of assertion. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets, liabilities, and equity that are not readily apparent from other sources. Actual results and outcomes could differ from these estimates and assumptions.
Fair Value Measurements	(c) Fair Value Measurements The Company measures certain assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that is expected to be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company uses a three-level hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques. The three levels of the fair value hierarchy are described below: Level 1: Quoted (unadjusted) prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2: Inputs other than quoted prices that are either directly or indirectly observable, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3: Inputs that are generally unobservable, supported by little or no market activity, and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The categorization of an asset or liability within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The valuation techniques used by the Company when measuring fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The Company also estimates the fair value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses, accrued compensation and employee benefits, and accrued restructuring costs. The Company considers the carrying value of these instruments in the financial statements to approximate fair value due to their short maturities.
Cash and Cash Equivalents and Restricted Cash	(d) Cash and Cash Equivalents and Restricted Cash Cash equivalents include bank demand deposits, money market instruments, certificates of deposit, U.S. Treasury securities, and equivalent funds. The Company generally considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Restricted cash consists of cash balances restricted in use by contractual obligations with third parties.
Short-term Investments	(e) Short-term Investments The Company periodically invests a portion of its excess cash in short-term investment instruments. All highly liquid investments with stated maturity dates between three months and one year from the purchase date are classified as short-term investments. The Company determines the appropriate classification of its short-term investments at the time of purchase. Substantially all of the Company’s short-term investments are in U.S. Treasury securities and certificates of deposit, and the Company has the ability and intent to hold these investments to maturity. Therefore, these short-term investments are classified and accounted for as held-to-maturity and are reported at amortized cost. Each reporting period, the Company determines whether a decline in fair value below the amortized cost for each individual security is other-than-temporary and if it would be required to sell the security before recovery of its amortized cost basis. If an other-than-temporary impairment has occurred, the amount representing the credit loss is recorded in “Other income, net,” and the amount related to all other factors is recognized in “Accumulated other comprehensive income (loss).” Upon recognition of an other-than-temporary impairment, the previous amortized cost basis less the other-than-temporary impairment recognized in earnings becomes the new amortized cost basis of the investment.
Derivative Financial Instruments	(f) Derivative Financial Instruments The Company is exposed to certain risks related to its ongoing business operations, including the effect of changes in foreign exchange rates on the Company’s monetary assets and liabilities denominated in foreign currency. The Company may use foreign currency forward contracts as part of its strategy to manage these risks, but does not hold or issue derivative instruments for trading purposes or speculation. The Company executes these instruments with financial institutions that hold an investment grade credit rating. These foreign currency forward contracts do not meet the requirements for hedge accounting and are recorded on the balance sheet as either an asset or liability measured at their fair value as of the reporting date. Changes in the fair value of derivative instruments, as measured using the three-level hierarchy described above, are recognized in “Other income, net” in the Company’s Consolidated Statements of Operations.
Property and Equipment	(g) Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, as follows: three years for computer equipment and purchased software; five years for office equipment and automobiles; and ten years for office furniture and owned corporate aircraft, which has an estimated salvage value of 70%. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the improvements or the term of the lease, whichever is shorter. The Company periodically evaluates the appropriateness of the estimated useful lives and salvage value of all property and equipment. Any change in the estimated useful life or salvage value is treated as a change in estimate and accounted for prospectively in the period of change. Expenditures for maintenance and repairs are charged to expense as incurred, except for certain costs related to the aircraft. The costs of normal, recurring, or periodic repairs and maintenance activities related to the aircraft are expensed as incurred. The cost of planned major maintenance activities (“PMMA”) may be treated differently because those activities may involve the acquisition of additional aircraft components or the replacement of existing aircraft components. PMMA are performed periodically based on passage of time and the use of the aircraft. The classification of a maintenance activity as part of PMMA requires judgment and can affect the amount of expense recognized in any particular period. The cost of each PMMA is expected to be capitalized and amortized over the period until the next scheduled PMMA. There have been no PMMA to date. When assets are retired or sold, the capitalized cost and related accumulated depreciation are removed from the property and equipment accounts and any resulting gain or loss is recognized in the results of operations. Eligible internal-use software development costs are capitalized subsequent to the completion of the preliminary project stage. Such costs include external direct material and service costs, employee payroll, and payroll-related costs. After all substantial testing and deployment is completed and the software is ready for its intended use, capitalization ceases and internal-use software development costs are amortized using the straight-line method over the estimated useful life of the software, generally three years. The Company reviews long-lived assets, including intangible assets, for impairment annually or whenever events or changes in business circumstances indicate that the carrying value of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the undiscounted cash flows to the recorded value of the asset. If an asset is impaired, the asset is written down by the amount by which the carrying value of the asset exceeds the related fair value of the asset.
Software Development Costs	(h) Software Development Costs Software development costs are expensed as incurred until technological feasibility has been established, at which time such costs are capitalized until the product is available for general release to customers. Capitalized software development costs include direct labor costs and fringe benefit costs attributed to programmers, software engineers, and quality control and field certifiers working on products after they reach technological feasibility, but before they are generally available to customers for sale. Technological feasibility is considered to be achieved when a product design and working model of the software product have been completed. Capitalized software development costs are typically amortized over the estimated product life of three years, on a straight-line basis. Recently, the Company has significantly improved the pace of its software development efforts and increased the frequency of its software releases, such that the period between technological feasibility and general release has been significantly reduced, resulting in no software development costs capitalized subsequent to the release of MicroStrategy 10. Capitalized software development costs, net of accumulated amortization, were $8.5 million and $15.9 million as of December 31, 2016 and 2015, respectively. Amortization expense related to software development costs was $7.4 million, $7.2 million, and $5.2 million for the years ended December 31, 2016, 2015, and 2014, respectively, and is included in cost of product licenses and subscription services revenues. During the years ended December 31, 2015 and 2014, the Company capitalized software development costs of $9.6 million and $8.4 million, respectively. The Company did not capitalize any software development costs during the year ended December 31, 2016. The Company analyzes the net realizable value of capitalized software development costs on at least an annual basis and has determined that there is no indication of impairment of the capitalized software development costs as forecasted future sales are adequate to support amortization costs.
Restructuring Costs	(i) Restructuring Costs In 2014, the Company committed to, and substantially implemented, a restructuring plan (the “2014 Restructuring Plan”). In connection with the 2014 Restructuring Plan, the Company has incurred restructuring related costs, including employee severance and related benefit costs, contract termination costs, and other related costs. See Note 8, Restructuring, to the Consolidated Financial Statements for further information on the Company’s current restructuring activities. Employee severance and related benefit costs may include cash payments, outplacement services, continuing health insurance coverage, and other benefits. Where no substantive severance or benefit plan relating to the involuntary termination of employees previously exists, these severance costs are generally considered “one-time” benefits and recognized at fair value in the period in which the liability is incurred, which is generally when management has approved and communicated to the terminated employees a detailed plan of termination. Severance costs pursuant to ongoing-benefit arrangements, including statutorily mandated termination benefits or termination benefits provided for in existing employment contracts, are recognized when probable and reasonably estimable. Severance costs are reasonably estimated based on the mix of staffing composition and geography. Where termination benefits are offered for a short period of time in exchange for voluntary termination, severance costs are recognized when the employee has irrevocably accepted the offer. Contract termination costs may include costs to exit office space under existing operating leases and consist of both costs to terminate the contract before the end of the term and costs that will continue to be incurred under the contract for the remaining term without economic benefit to the Company. Costs to terminate the contract before the term has ended are recognized at fair value when the Company terminates the contract in accordance with the contract terms. Costs that will continue to be incurred under the contract for the remaining term without economic benefit to the Company (for example, remaining lease rental payments and executory costs) are recognized at fair value in the period in which the Company ceases using the right conveyed by the contract (for example, when the leased space ceases to be used). In the case of operating leases, these continuing costs are also adjusted for the effects of any prepaid or deferred items previously recognized under the lease and reduced by estimated sublease rental income. Other related costs generally include employee relocation costs, office moving costs, and external consulting and advisory fees related to restructuring activities, including the liquidation of certain foreign subsidiaries. Such costs are recognized at fair value in the period in which the costs are incurred. At each reporting date, the Company evaluates its accrued restructuring costs to determine if the liabilities reported are still appropriate. Any changes to the estimated costs of executing approved restructuring plans are reflected in the Company’s Consolidated Statements of Operations.
Loss Contingencies and Legal Costs	(j) Loss Contingencies and Legal Costs The Company accrues loss contingencies that are believed to be probable and can be reasonably estimated. As events evolve during the administration and litigation process and additional information becomes known, the Company reassesses its estimates related to loss contingencies. Legal costs are expensed in the period in which the costs are incurred.
Deferred Revenue and Advance Payments	(k) Deferred Revenue and Advance Payments Deferred revenue and advance payments related to product support, subscription services, and other services result from payments received prior to the performance of services for technical support, subscription, consulting, and education. Deferred revenue and advance payments related to product licenses result primarily from multiple-element arrangements that include future deliverables. Deferred revenue is comprised of deferred product licenses and subscription services, deferred product support, or other services revenue based on the objective fair value of the multiple elements of the arrangement, except for software licenses for which the Company does not have an objective measure of fair value. The Company offsets its accounts receivable and deferred revenue for any billed and unpaid items included in deferred revenue and advance payments.
Revenue Recognition	(l) Revenue Recognition The Company recognizes revenue from sales of software licenses to end users upon: 1) persuasive evidence of an arrangement, as provided by agreements, contracts, purchase orders, or other arrangements, generally executed by both parties; 2) existence of a fixed or determinable fee; 3) delivery of the software; and 4) determination that collection is reasonably assured. When the fees for software upgrades and enhancements, technical support, consulting, and education are bundled with the license fee, they are unbundled for revenue recognition purposes, using vendor specific objective evidence (“VSOE”) of fair value of the elements. Product support or post-contract support (“PCS”) revenue is derived from providing technical software support and software updates and upgrades to customers. PCS revenue is recognized ratably over the term of the contract, which in most cases is one year. The Company’s VSOE for PCS, which includes updates, upgrades, and enhancements, is determined based on the optional stated renewal fee for PCS in the contract, which is the price the customer is required to pay when PCS is renewed. Additionally, the optional stated renewal fee used to establish VSOE for PCS in a software transaction must be above the Company’s minimum substantive VSOE rate for PCS. If a stated renewal rate is considered non-substantive, VSOE of PCS has not been established and the Company recognizes all revenue under the arrangement ratably over the PCS period. A minimum substantive VSOE rate is determined based on an analysis of historical sales of PCS. For a renewal rate to be non-substantive, the Company believes it must be significantly lower than its minimum VSOE rate. The Company considers a 10% variance below its minimum VSOE rate to be significant. It is rare for the Company to have an arrangement that includes a renewal rate that is below the minimum VSOE rate. Revenue from consulting, education, and subscription services is recognized as the services are performed. The Company’s VSOE for services other than PCS is determined based on an analysis of its historical sales of each element when sold separately from software. For new offerings of services other than PCS or service offerings that have not had a sufficient history of sales activity, the Company initially establishes VSOE based on the list price as determined by management with the relevant authority. Each service offering has a single list price in each country where sold. If VSOE exists for all undelivered elements and there is no such evidence of fair value established for delivered elements, the arrangement fee is first allocated to the elements where evidence of fair value has been established and the residual amount is allocated to the delivered elements. If evidence of fair value for any undelivered element of an arrangement does not exist, all revenue from the arrangement is deferred until such time that evidence of fair value exists for undelivered elements or until all elements of the arrangement are delivered, subject to certain limited exceptions. If an arrangement includes acceptance criteria, revenue is not recognized until the Company can objectively demonstrate that the software or service can meet the acceptance criteria, or the acceptance period lapses, whichever occurs earlier. If a software license arrangement obligates the Company to deliver specified future products or upgrades, revenue is recognized when the specified future product or upgrades are delivered, or when the obligation to deliver specified future products expires, whichever occurs earlier. If a software license arrangement obligates the Company to deliver unspecified future products, then revenue is recognized on a subscription basis, ratably over the term of the contract. License revenue derived from sales to resellers or original equipment manufacturers who purchase the Company’s products for resale is recognized upon sufficient evidence that the products have been sold to the end user, provided all other revenue recognition criteria have been met. The Company’s standard software license and reseller agreements do not include any return rights other than the right to return non-conforming products for repair or replacement under standard product warranties. During the last three fiscal years, the Company has not experienced any product returns related to warranty claims. The Company generally offers either commercial discounts or referral fees to its channel partners, depending on the nature of services performed. Revenue recognized from transactions with channel partners involved in resale or distribution activities is recorded net of any commercial discounts provided to them. Referral fees paid to channel partners not involved in resale or distribution activities are expensed as cost of revenues and, during the last three fiscal years, were not significant. The Company’s standard software license agreements do not include any price protection provisions. However, transactions under the General Services Administration Federal Supply Schedule contract must comply with the Price Reductions clause. In addition, certain government agencies have the right to cancel contracts for “convenience.” During the last three fiscal years, there were no material amounts refunded under the Price Reductions clause and there were no material contracts cancelled for convenience. Amounts collected prior to satisfying the above revenue recognition criteria are included in net deferred revenue and advance payments in the accompanying Consolidated Balance Sheets. Software revenue recognition requires judgment, including determinations about whether collectability is reasonably assured, the fee is fixed and determinable, a software arrangement includes multiple elements, and if so, whether VSOE exists for those elements. Judgment is also required to assess whether future releases of certain software represent new products or upgrades and enhancements to existing products. The Company also generates subscription services revenues primarily from its cloud services offerings. Subscription services revenues include subscription fees from customers for access to the full breadth of MicroStrategy Analytics and MicroStrategy Mobile capabilities, database services, and data integration services. The Company’s standard arrangements with customers generally do not provide the customer with the right to take possession of the software supporting the cloud-based application service at any time. As such, these arrangements are considered service contracts and revenue is recognized ratably over the service period of the contract, following completion of the set-up service. Any related set-up service fees are recognized ratably over the longer of the contract period or the estimated average life of the customer relationship. The Company’s subscription services are generally offered as standalone arrangements or as part of arrangements that include professional services. If deliverables in a multiple-element arrangement have standalone value upon delivery, the Company accounts for each such deliverable separately. The Company has concluded that its subscription services and its professional services each have standalone value. When the Company enters into multiple-element arrangements that include subscription services and professional services, the total arrangement consideration is allocated to each of the deliverables based on the relative selling price hierarchy. The Company determines the relative selling price for each deliverable using VSOE of selling price, if available, or its best estimate of selling price (“BESP”), if VSOE is not available. The Company has determined that third-party evidence of selling price (“TPE”) is not a practical alternative due to differences in its services offerings as compared to other companies and the lack of availability of third-party pricing information. For professional services, the Company has established VSOE because a consistent number of standalone sales of this deliverable have been priced within a reasonably narrow range. For subscription services, the Company has not established VSOE because, among other factors, the offering is relatively new and its pricing model continues to evolve. Accordingly, the Company uses BESP to determine the relative selling price of its subscription services. The Company determines BESP by reviewing historical transactions and by considering the service’s pricing models and objectives that take into account factors such as gross margin, the size and volume of the transactions, perceived pricing sensitivity, and growth strategies. The determination of BESP is made through consultation with, and approval by, the Company’s management team, taking into consideration the go-to-market strategy. As the Company’s pricing and go-to-market strategies evolve, the Company may modify its pricing practices in the future, which could result in changes to the determination of VSOE and BESP. Amounts, upon invoicing, are recorded in accounts receivable and either gross deferred revenue or revenue, depending on whether the applicable revenue recognition criteria have been met. During 2016, 2015, and 2014, the Company did not generate significant revenues from Usher.
Advertising Costs	(m) Advertising Costs Advertising costs include production costs, which are expensed the first time the advertisement takes place, and media placement costs, which are expensed in the month the advertising appears. Total advertising costs were $1.3 million, $0.5 million, and $3.0 million for the years ended December 31, 2016, 2015, and 2014, respectively. As of December 31, 2016 and 2015, the Company had no prepaid advertising costs.
Share-based Compensation	(n) Share-based Compensation The Company maintains its 2013 Stock Incentive Plan (as amended, the “2013 Equity Plan”), under which the Company’s employees, officers, directors, and other eligible participants may be awarded various types of share-based compensation, including options to purchase shares of the Company’s class A common stock. The Company recognizes share-based compensation expense associated with such stock option awards on a straight-line basis over the award’s requisite service period (generally, the vesting period). The share-based compensation expense is based on the fair value of such awards on the date of grant, as estimated using the Black-Scholes option pricing model. See Note 12, Share-based Compensation, to the Consolidated Financial Statements for further information regarding the 2013 Equity Plan, related share-based compensation expense, and assumptions used in the Black-Scholes option pricing model.
Income Taxes	(o) Income Taxes The Company is subject to federal, state, and local income taxes in the United States and many foreign countries. Deferred income taxes are provided based on enacted tax laws and rates applicable to the periods in which the taxes become payable. For uncertain income tax positions, the Company uses a more-likely-than-not recognition threshold based on the technical merits of the income tax position taken. Income tax positions that meet the more-likely-than-not recognition threshold are measured in order to determine the tax benefit recognized in the financial statements. The Company recognizes accrued interest related to unrecognized tax benefits as part of income tax expense. Penalties, if incurred, are recognized as a component of income tax expense. The Company provides a valuation allowance to reduce deferred tax assets to their estimated realizable value, when appropriate.
Basic and Diluted Earnings Per Share	(p) Basic and Diluted Earnings Per Share Basic earnings per share is determined by dividing the net income attributable to common stockholders by the weighted average number of common shares and participating securities outstanding during the period. Participating securities are included in the basic earnings per share calculation when dilutive. Diluted earnings per share is determined by dividing the net income attributable to common stockholders by the weighted average number of common shares and potential common shares outstanding during the period. Potential common shares are included in the diluted earnings per share calculation when dilutive. Potential common shares consisting of common stock issuable upon exercise of outstanding employee stock options and warrants are computed using the treasury stock method. Potential common shares also consist of common stock issuable upon the conversion of preferred stock. The Company has two classes of common stock: class A common stock and class B common stock. Holders of class A common stock generally have the same rights, including rights to dividends, as holders of class B common stock, except that holders of class A common stock have one vote per share while holders of class B common stock have ten votes per share. Each share of class B common stock is convertible at any time, at the option of the holder, into one share of class A common stock. As such, basic and fully diluted earnings per share for class A and class B common stock are the same. The Company has never declared or paid any cash dividends on either class A or class B common stock. As of December 31, 2016 and 2015, there were no shares of preferred stock outstanding.
Foreign Currency Translation	(q) Foreign Currency Translation The functional currency of the Company’s international operations is the local currency. Accordingly, all assets and liabilities of international subsidiaries are translated using exchange rates in effect at the end of the period, and revenue and expenses are translated using weighted average exchange rates for the period. The related translation adjustments are reported in “Accumulated other comprehensive income (loss)” in stockholders’ equity. In general, upon complete or substantially complete liquidation of an investment in an international subsidiary, the amount of accumulated translation adjustments attributable to that subsidiary is reclassified from stockholders’ equity to the statement of operations. Transaction gains and losses arising from transactions denominated in a currency other than the functional currency of the entity involved are included in the results of operations. In 2015, as a result of the completion of the liquidation of one of the Company’s foreign subsidiaries as part of the 2014 Restructuring Plan, a $0.3 million foreign currency translation gain was reclassified from “Accumulated other comprehensive loss” in the accompanying Consolidated Balance Sheets to “Other income, net” in the accompanying Consolidated Statements of Operations. No reclassifications were recorded in 2016 or 2014. As of December 31, 2016, 2015, and 2014, the cumulative foreign currency translation balances were $(10.8) million, $(7.4) million, and $(4.4) million, respectively. Since the Company intends to indefinitely reinvest its undistributed earnings of all of its subsidiaries, no taxes were recognized on the temporary differences resulting from foreign currency translation adjustments for the years ended December 31, 2016, 2015, and 2014. Transaction gains and losses arising from transactions denominated in foreign currencies resulted in net gains of $3.0, $2.4, and $5.3 million in 2016, 2015, and 2014, respectively, and are included in “Other income, net” in the accompanying Consolidated Statements of Operations.
Concentrations of Credit Risk	(r) Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, short-term investments, foreign currency forward contracts, and accounts receivable. The Company places its cash equivalents and enters into foreign currency forward contracts with high credit-quality financial institutions and invests its excess cash primarily in short-term investments. The Company has established guidelines relative to credit ratings and maturities that seek to maintain safety and liquidity. The Company sells products and services to various companies across several industries throughout the world in the ordinary course of business. The Company routinely assesses the financial strength of its customers and maintains allowances for anticipated losses. As of December 31, 2016 and 2015, no individual customer accounted for 10% or more of net accounts receivable, and for the years ended December 31, 2016, 2015, and 2014, no individual customer accounted for 10% or more of revenue.
