Accounting Policies [Abstract]
General	NOTE 1. GENERAL Business . Prologis, Inc. (or the “Parent”) commenced operations as a fully integrated real estate company in 1997, elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and believes the current organization and method of operation will enable it to maintain its status as a REIT. The Parent is the general partner of Prologis, L.P. (or the “Operating Partnership” or “OP”). Through the OP, we are engaged in the ownership, acquisition, development and management of logistics facilities with a focus on high-barrier, high-growth markets in 19 countries. We invest in real estate through wholly owned subsidiaries and other entities through which we co-invest with partners and investors. We maintain a significant level of ownership in these co-investment ventures, which may be consolidated or unconsolidated based on our level of control of the entity. Our current business strategy consists of two operating business segments: Real Estate Operations and Strategic Capital. Our Real Estate Operations segment represents the ownership and development of logistics properties. Our Strategic Capital segment represents the management of unconsolidated co-investment ventures. See Note 11 for further discussion of our business segments. Unless otherwise indicated, the Notes to the Consolidated Financial Statements apply to both the Parent and the OP. The terms “the Company,” “Prologis,” “we,” “our” or “us” means the Parent and OP collectively. For each share of preferred or common stock the Parent issues, the OP issues a corresponding preferred or common partnership unit, as applicable, to the Parent in exchange for the contribution of the proceeds from the stock issuance. At September 30, 2018, the Parent owned 97.07% common general partnership interest in the OP and 100% of the preferred units in the OP. The remaining 2.93% common limited partnership interests, which include 8.8 million Class A common limited partnership units (“Class A Units”) in the OP, are owned by unaffiliated investors and certain current and former directors and officers of the Parent. Each partner’s percentage interest in the OP is determined based on the number of OP units held, including the number of OP units into which Class A Units are convertible, compared to total OP units outstanding at each period end and is used as the basis for the allocation of net income or loss to each partner. At the end of each reporting period, a capital adjustment is made in the OP to reflect the appropriate ownership interest for each of the common unitholders. These adjustments are reflected in the line items Reallocation of Equity Reallocation of Capital As the sole general partner of the OP, the Parent has complete responsibility and discretion in the day-to-day management and control of the OP and we operate the Parent and the OP as one enterprise. The management of the Parent consists of the same members as the management of the OP. These members are officers of the Parent and employees of the OP or one of its subsidiaries. As general partner with control of the OP, the Parent is the primary beneficiary and therefore consolidates the OP. Because the Parent’s only significant asset is its investment in the OP, the assets and liabilities of the Parent and the OP are the same on their respective financial statements. Basis of Presentation. The accompanying Consolidated Financial Statements are prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) and are presented in our reporting currency, the U.S. dollar. All material intercompany transactions with consolidated entities have been eliminated. The accompanying unaudited interim financial information has been prepared according to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and note disclosures normally included in our annual financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with such rules and regulations. Our management believes that the disclosures presented in these financial statements are adequate to make the information presented not misleading. In our opinion, all adjustments and eliminations, consisting only of normal recurring adjustments, necessary to present fairly the financial position and results of operations for both the Parent and the OP for the reported periods have been included. The results of operations for such interim periods are not necessarily indicative of the results for the full year. The accompanying unaudited interim financial information should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the SEC, and other public information. New Accounting Pronouncements. New Accounting Standards Adopted Revenue Recognition . In May 2014, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update (“ASU”) that requires companies to use a five-step model to determine when to recognize revenue from customer contracts in an effort to increase consistency and comparability throughout global capital markets and across industries. In February 2017, the FASB issued an additional ASU that provides the accounting treatment for gains and losses from the derecognition of non-financial assets, including the accounting for partial sales of real estate properties. We adopted the revenue recognition and derecognition of non-financial assets standards (collectively “the new revenue recognition standard”) on January 1, 2018, on a modified retrospective basis. Rental revenues and recoveries earned from leasing our operating properties are excluded from this ASU and will be assessed with the adoption of the lease ASU discussed below. Our evaluation under the new revenue recognition standard included recurring and transactional fees and incentive fees (“promotes” or “promote revenues”) earned from our co-investment ventures as well as dispositions and contributions of real estate properties. There is no change in our recognition of recurring and transactional fees as we will continue to recognize these fees as we provide the services. Promote revenues are earned based on a venture’s cumulative returns over a certain time-period and the returns are determined by both the operating performance and real estate valuation of the venture, including highly variable inputs such as capitalization rates, market rents, interest rates and foreign currency exchange rates. As these key inputs are highly volatile and out of our control, and such volatility can materially impact our promotes period over period, we expect promote revenues will continue to be recognized at or near the end of the performance period. Accordingly, we do not expect significant changes in promote revenue recognition as a result of this ASU. For dispositions of real estate properties to third parties, the ASU will not impact the recognition of the sale. Beginning January 1, 2018, we recognized the entire gain attributed to contributions of real estate properties to unconsolidated co-investment ventures. We previously recognized a gain on contribution only to the extent of the third-party ownership in the unconsolidated co-investment venture acquiring the property and deferred the portion of the gain related to our ownership. We adopted the practical expedient to only assess the recognition of revenue for open contracts during the transition period and there was no adjustment to the opening balance of retained earnings at January 1, 2018. The comparative information has not been restated and continues to be reported under the accounting standards in effect for that period. New Accounting Standards Issued but not yet Adopted Leases. In February 2016, the FASB issued an ASU that provides the principles for the recognition, measurement, presentation and disclosure of leases. In July 2018, the FASB issued an additional ASU that provided for targeted improvements to the February 2016 ASU. We refer to both ASUs collectively as the new lease standard. • As a lessor. The accounting for lessors will remain largely unchanged from current GAAP; however, the new lease standard requires that lessors expense, on an as-incurred basis, certain initial direct costs that are not incremental in negotiating a lease. Under existing standards, these costs are capitalizable and therefore the new lease standard will result in certain of these costs being expensed as incurred after adoption. During the nine months ended September 30, 2018 and 2017, we capitalized $15.7 million and $17.9 million, respectively, of internal costs related to our leasing activities. The new lease standard provides lessors a practical expedient to not separate rental recovery revenue from the associated rental revenue if certain criteria are met. We assessed these criteria and concluded that the timing and pattern of transfer for rental recoveries and the associated rental revenue are the same and our leases will continue to qualify as operating leases under which we will recognize rental revenue, and therefore we will account for and present rental revenue and rental recovery revenue as a single component. • As a lessee. Under the new lease standard, lessees apply a dual approach, classifying leases as either finance or operating leases. A lessee is required to record a right-of-use (“ROU”) asset and a lease liability for all leases with a term of greater than 12 months, regardless of their lease classification. We are a lessee of ground leases and office space leases. At September 30, 2018 we had approximately 100 ground and office space leases that will require us to measure and record a ROU asset and a lease liability upon adoption. Details of our future minimum rental payments under ground and office space leases at December 31, 2017 are disclosed in Note 4 to the Annual Report on Form 10-K for the year ended December 31, 2017. The new lease standard is effective for us on January 1, 2019 and we will apply it prospectively. We expect to adopt the practical expedients available for implementation. By adopting these practical expedients, we will not be required to reassess the following and therefore we do not expect an adjustment to the opening balance of retained earnings: (i) whether an expired or existing contract meets the definition of a lease; (ii) the lease classification at the adoption date for existing leases; and (iii) whether costs previously capitalized as initial direct costs would continue to be amortized. This allows us to continue to account for our ground and office space leases as operating leases, however, any new or renewed ground leases may be classified as financing leases unless they meet certain conditions to be considered a lease involving land owned by a government unit or authority. The new lease standard will also require new disclosures within the accompanying notes to the Consolidated Financial Statements. We are completing our evaluation of the key drivers, such as the discount rate, in the measurement of the ROU asset and lease liability and the quantitative impact that adoption will have on the Consolidated Financial Statements in the future. Derivatives and Hedging . In August 2017, the FASB issued an ASU that simplifies the application of hedge accounting guidance in current GAAP and improves the reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its consolidated financial statements. Among the simplification updates, the ASU eliminates the requirement in current GAAP to separately recognize periodic hedge ineffectiveness. Mismatches between the changes in value of the hedged item and hedging instrument may still occur but they will no longer be separately reported. The ASU requires the presentation of the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. The ASU is effective for us on January 1, 2019. We do not expect the adoption of this ASU to have a material impact on the Consolidated Financial Statements.

DCT Transaction

Business Combinations [Abstract]
DCT Transaction	NOTE 2. DCT TRANSACTION On August 22, 2018, DCT Industrial Trust Inc. (“DCT Inc.”) merged with and into Prologis, Inc., with Prologis, Inc. surviving the merger (the “Company Merger”) and immediately prior to the effective time of the Company Merger, DCT Industrial Operating Partnership LP (“DCT OP”) merged with and into Prologis, L.P., with Prologis, L.P. surviving the merger (the “Partnership Merger” and, together with the Company Merger, the “DCT Transaction”). The term “DCT” means DCT Inc. and DCT OP collectively. The DCT Transaction was completed for $8.5 billion through the issuance of equity based on the closing price of Prologis’ common stock on August 21, 2018 and the assumption of debt. In connection with the transaction, each issued and outstanding share or unit held by a DCT stockholder or unitholder was converted automatically into 1.02 shares of Prologis common stock or common units of Prologis, L.P., respectively, including shares and units under DCT’s equity incentive plan that became fully vested at closing. Through the DCT Transaction, we acquired a portfolio of logistics real estate assets that consisted of 408 operating properties, aggregating 68.0 million square feet, 10 properties under development, aggregating 2.8 million square feet and 305 acres of land parcels with build-out potential of 4.5 million square feet. The aggregate equity consideration of approximately $6.6 billion is calculated below (in millions, except price per share): Number of Prologis shares and units issued upon conversion of DCT shares and units at August 21, 2018 99.73 Multiplied by price of Prologis' common stock on August 21, 2018 $ 65.75 Fair value of Prologis shares and units issued $ 6,557 W e accounted for the DCT Transaction as an asset acquisition and as a result the transaction costs of $50.0 million were capitalized to the basis of the acquired properties. Under acquisition accounting, the total purchase price was allocated to the DCT net tangible and identifiable intangible assets acquired and liabilities assumed based on their relative fair values. The purchase price allocation of DCT resulted primarily in investments in real estate properties and related net intangible assets of $8.5 billion that was financed by the issuance of Prologis shares and units of $6.6 billion and the assumption of debt of $1.9 billion.

Unconsolidated Entities	NOTE 4. UNCONSOLIDATED ENTITIES Summary of Investments We have investments in entities through a variety of ventures. We co-invest in entities that own multiple properties with partners and investors and we provide asset and property management services to these entities, which we refer to as co-investment ventures. These entities may be consolidated or unconsolidated, depending on the structure, our partner’s participation and other rights and our level of control of the entity. This note details our investments in unconsolidated co-investment ventures, which are accounted for using the equity method of accounting. See Note 7 for more detail regarding our consolidated investments that are not wholly owned. We also have other ventures, generally with one partner and that we do not manage, which we account for using the equity method. We refer to our investments in all entities accounted for using the equity method, both unconsolidated co-investment ventures and other ventures, collectively, as unconsolidated entities.

The difference between our ownership interest of a venture’s equity and our investment balance at September 30, 2018 and December 31, 2017, results principally from three types of transactions: (i) deferred gains from the contribution of property to a venture prior to January 1, 2018 ($648.1 million and $667.3 million, respectively); (ii) recording additional costs associated with our investment in the venture ($91.4 million and $94.2 million, respectively); and (iii) advances to a venture ($217.6 million and $210.0 million, respectively). For deferred gains from partial sales recorded prior to the adoption of the new revenue recognition standard, we will continue to recognize these gains over the lives of the underlying real estate properties or at the time of disposition to a third party. (3) Represents our weighted average ownership interest in all co-investment ventures based on each entity’s contribution of total assets, before depreciation, net of other liabilities.

Debt Disclosure [Abstract]
Debt	NOTE 6. DEBT All debt is incurred by the OP or its consolidated subsidiaries. The Parent does not have any indebtedness, but guarantees the unsecured debt issued by the OP. The following table summarizes our debt (dollars in thousands): September 30, 2018 December 31, 2017 Weighted Average Interest Rate (1) Amount Outstanding (2) (3) Weighted Average Interest Rate (1) Amount Outstanding (2) Credit facilities 0.8 % $ 235,822 1.8 % $ 317,392 Senior notes 2.7 % 8,353,096 3.0 % 6,067,277 Term loans 1.5 % 1,765,300 1.7 % 2,046,945 Unsecured other 6.1 % 13,093 6.1 % 13,546 Secured mortgages 5.3 % 864,818 5.3 % 967,471 Total 2.7 % $ 11,232,129 2.9 % $ 9,412,631 (1) The interest rates presented represent the effective interest rates (including amortization of debt issuance costs and the noncash premiums or discounts) at the end of the period for the debt outstanding and include the impact of undesignated and designated interest rate swaps, which effectively fix the interest rate on our variable rate debt. (2) Included in the outstanding balances were borrowings denominated in non-U.S. dollars. The following table summarizes our debt by currency: September 30, 2018 December 31, 2017 British pound sterling $ 648,184 $ 671,522 Canadian dollar 279,184 451,080 Euro 5,166,017 3,839,422 Japanese yen 1,791,824 1,306,380 U.S. dollar 3,346,920 3,144,227 Total $ 11,232,129 $ 9,412,631 Generally, we borrow in the functional currency of the consolidated subsidiaries, but we also borrow in currencies other than the U.S. dollar in the OP and may designate this borrowing as a nonderivative financial instrument. We may also hedge our foreign currency risk by designating derivative financial instruments as net investment hedges, as these amounts offset the translation adjustments on the underlying net assets of our foreign investments. See Note 10 for more information about our nonderivative and derivative financial instruments. (3) Through the DCT Transaction, we assumed $1.9 billion of debt with a weighted average interest rate of 3.4%, which includes the noncash premium. Prior to September 30, 2018, we paid down $1.8 billion of the assumed debt. In order to pay down the debt, we utilized the proceeds principally from the issuance of the following senior notes: (i) in June 2018, $700.0 million senior notes due in September 2028 through 2048 with interest rates ranging from 3.9% to 4.4%; (ii) in July 2018, €700.0 million ($818.7 million) senior notes due in January 2029 with an interest rate of 1.9%; and (iii) in September 2018, ¥55.1 billion ($488.7 million) senior notes due in September 2025 through 2038 with interest rates ranging from 0.7% to 1.5%. The exchange rate used to calculate into U.S. dollars was the spot rate at the settlement date. Credit Facilities We have a global senior credit facility (the “Global Facility”), under which we may draw in British pounds sterling, Canadian dollars, euro, Japanese yen and U.S. dollars on a revolving basis up to $3.0 billion (subject to currency fluctuations). We have the ability to increase the Global Facility to $3.8 billion, subject to currency fluctuations and obtaining additional lender commitments. Pricing under the Global Facility, including the spread over LIBOR, facility fees and letter of credit fees, varies based on the public debt ratings of the OP. The Global Facility is scheduled to mature in April 2020; however, we may extend the maturity date for six months on two occasions, subject to the satisfaction of certain conditions and payment of extension fees. We also have a Japanese yen revolver (the “Revolver”) with availability of ¥50.0 billion ($441.1 million at September 30, 2018). We have the ability to increase the Revolver to ¥65.0 billion ($573.4 million at September 30, 2018), subject to obtaining additional lender commitments. Pricing under the Revolver, including the spread over LIBOR, facility fees and letter of credit fees, varies based on the public debt ratings of the OP. The Revolver is scheduled to mature in February 2021; however, we may extend the maturity date for one year, subject to the satisfaction of certain conditions and payment of extension fees. We refer to the Global Facility and the Revolver, collectively, as our “Credit Facilities.” The following table summarizes information about our Credit Facilities at September 30, 2018 (in millions): Aggregate lender commitments $ 3,453 Less: Borrowings outstanding 236 Outstanding letters of credit 32 Current availability $ 3,185 Senior Notes In January 2018, we issued €400.0 million ($494.2 million) of senior notes bearing a floating rate of Euribor plus 0.3%, maturing in January 2020. The exchange rate used to calculate into U.S. dollars was the spot rate at the settlement date . We also issued senior notes as described above to pay down debt assumed in the DCT Transaction of $1.8 billion, as well as for general corporate purposes. Term Loans During the nine months ended September 30, 2018, we borrowed on our Global Facility and paid down CAD 201.4 million ($158.9 million) on a Canadian term loan (“2015 Canadian Term Loan”) , leaving CAD 170.5 million ($131.0 million at September 30, 2018) outstanding During the nine months ended September 30, 2018 and 2017, we paid down $1.5 billion and $1.1 billion, respectively, and reborrowed $1.4 billion and $1.0 billion, respectively, on our 2017 Term Loan.

Included in the 2021 maturities was the Revolver that can be extended until 2022. Financial Debt Covenants We have $8.4 billion of senior notes and $1.8 billion of term loans outstanding at September 30, 2018 that were subject to certain financial covenants under their related indentures. We are also subject to financial covenants under our Credit Facilities and certain secured mortgage debt. At September 30, 2018, we were in compliance with all of our financial debt covenants. Guarantee of Finance Subsidiary Debt In July 2018, we formed a finance subsidiary as part of our operations in Europe, Prologis Euro Finance LLC (“Euro Finance Subsidiary”). In August 2018, we formed a finance subsidiary as part of our operations in Japan, Prologis Yen Finance LLC (“Yen Finance Subsidiary”). In October 2018, we formed a finance subsidiary as part of our operations in the United Kingdom, Prologis Sterling Finance LLC (“Sterling Finance Subsidiary”). The Euro Finance Subsidiary and Yen Finance Subsidiary are 100% indirectly owned by the OP and all unsecured debt issued by each entity is fully and unconditionally guaranteed by the OP. The Sterling Finance Subsidiary is 100% indirectly owned by the OP and all unsecured debt issued will be fully and unconditionally guaranteed by the OP. There are no restrictions or limits on the OP’s ability to obtain funds from its subsidiaries by dividend or loan. In reliance on Rule 3-10 of Regulation S-X, the separate financial statements of the Euro Finance Subsidiary, Yen Finance Subsidiary and Sterling Finance Subsidiary are not provided.

These entities include two real estate partnerships that have issued limited partnership units to third parties. Depending on the specific partnership agreements, these limited partnership units are redeemable for cash or, at our option, into shares of the Parent’s common stock, generally at a rate of one share of common stock to one unit. We also consolidate certain entities in which we do not own 100% of the equity but the equity of these entities is not exchangeable into our common stock. Prologis, Inc. The noncontrolling interests of the Parent include the noncontrolling interests for the OP, as well as the limited partnership units in the OP that are not owned by the Parent.

Long-Term Compensation	NOTE 8. LONG-TERM COMPENSATION Equity-Based Compensation Plans and Programs Prologis Outperformance Plan (“POP”) We allocate participation points to participants under our POP corresponding to three-year performance periods beginning January 1. The fair value of the awards is measured at the grant date and amortized over the period from the grant date to the date at which the awards vest, which range from three to ten years. POP awards are earned to the extent our three-year compound annualized total stockholder return (“TSR”) for the performance period is positive and exceeds the three-year compound annualized TSR for the Morgan Stanley Capital International (“MSCI”) US REIT Index for the same period plus 100 basis points. We granted participation points for the 2018 – 2020 performance period in January 2018, with a fair value of $23.3 million using a Monte Carlo valuation model that assumed a risk-free interest rate of 2.1% and an expected volatility of 16.5%. The 2018 – 2020 performance period has an absolute maximum cap of $100 million. If the award is earned then 20% of the POP award is paid at the end of the performance period and the remaining 80% is subject to additional seven-year cliff vesting. The 20% that is paid at the end of the three-year performance period is subject to an additional three-year holding requirement. The performance criteria were met for the 2015 – 2017 performance period, which resulted in awards being earned at December 31, 2017. An aggregate performance pool of $110.2 million was awarded in January 2018 in the form of 0.6 million shares of common stock and 1.2 million vested LTIP Units. Other Equity-Based Compensation Plans and Programs Our other equity-based compensation plans and programs include (i) the Prologis Promote Plan (“PPP”); (ii) the annual long-term incentive (“LTI”) equity award program (“Annual LTI Award”); and (iii) the annual bonus exchange program. Awards under these plans and programs may be issued in the form of restricted stock units (“RSUs”) or LTIP Units at the participant’s election. RSUs and LTIP Units are valued based on the market price of the Parent’s common stock on the date the award is granted and is charged to compensation expense over the service period. Beginning in February 2018 with awards for PPP and Annual LTI Awards, the service period is four years.

Fair Value Measurements on a Recurring Basis At September 30, 2018 and December 31, 2017, other than the derivatives discussed previously, we did not have any significant financial assets or financial liabilities that were measured at fair value on a recurring basis in the Consolidated Financial Statements. All of our derivatives held at September 30, 2018 and December 31, 2017, were classified as Level 2 of the fair value hierarchy. Fair Value Measurements on Nonrecurring Basis Acquired properties and assets we expect to sell or contribute met the criteria to be measured on a nonrecurring basis at fair value and the lower of their carrying amount or their estimated fair value less the costs to sell, respectively, at September 30, 2018 and December 31, 2017. At September 30, 2018 and December 31, 2017, we estimate the fair value of our properties using Level 2 or Level 3 inputs from the fair value hierarchy. See more information on our acquired properties and assets held for sale or contribution in Notes 2, 3 and 5, respectively. Fair Value of Financial Instruments At September 30, 2018 and December 31, 2017, the carrying amounts of certain financial instruments, including cash and cash equivalents, accounts and notes receivable, accounts payable and accrued expenses were representative of their fair values. The differences in the fair value of our debt from the carrying value in the table below were the result of differences in interest rates or borrowing spreads that were available to us at September 30, 2018 and December 31, 2017, as compared with those in effect when the debt was issued or assumed, including reduced borrowing spreads due to our improved credit ratings. The senior notes and many of the issuances of secured mortgage debt contain pre-payment penalties or yield maintenance provisions that could make the cost of refinancing the debt at lower rates exceed the benefit that would be derived from doing so.

Segment Reporting [Abstract]
Business Segments	NOTE 11. BUSINESS SEGMENTS Our current business strategy consists of two operating segments: Real Estate Operations and Strategic Capital. We generate revenues, net operating income, earnings and cash flows through our segments, as follows: • Real Estate Operations. This operating segment represents the ownership and development of operating properties and is the largest component of our revenues and earnings. We collect rent from our customers through operating leases, including reimbursements for the majority of our property operating costs. Each operating property is considered to be an individual operating segment with similar economic characteristics; these properties are combined within the reportable business segment based on geographic location. Our Real Estate Operations segment also includes development activities that lead to rental operations, including land held for development and properties currently under development. Within this line of business, we utilize the following: (i) our land bank; (ii) the development expertise of our local teams; and (iii) our customer relationships. Land we own and lease to customers under ground leases is also included in this segment. • Strategic Capital. This operating segment represents the management of unconsolidated co-investment ventures. We generate strategic capital revenues primarily from our unconsolidated co-investment ventures through asset and property management services and we earn additional revenues by providing leasing, acquisition, construction, development, financing, legal and disposition services. Depending on the structure of the venture and the returns provided to our partners, we also earn revenues through promotes periodically during the life of a venture or upon liquidation. Each unconsolidated co-investment venture we manage is considered to be an individual operating segment with similar economic characteristics; these ventures are combined within the reportable business segment based on geographic location. Reconciliations are presented below for: (i) each reportable business segment’s revenues from external customers to Total Revenues Operating Income Earnings Before Income Taxes Total Assets Total Revenues, Operating Income, Earnings Before Income Taxes Total Assets Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 Segment revenues: Real estate operations segment: U.S. $ 556,314 $ 478,718 $ 1,546,622 $ 1,532,706 Other Americas 29,091 23,157 89,470 54,690 Europe 13,806 16,369 43,916 56,676 Asia 12,079 16,588 37,556 48,399 Total real estate operations segment 611,290 534,832 1,717,564 1,692,471 Strategic capital segment: U.S. 19,040 17,340 53,014 159,925 Other Americas 6,979 6,061 25,388 21,976 Europe 29,371 26,289 96,676 78,524 Asia 15,752 18,352 104,722 45,316 Total strategic capital segment 71,142 68,042 279,800 305,741 Total segment revenues 682,432 602,874 1,997,364 1,998,212 Segment net operating income: Real estate operations segment: U.S. (1) 422,682 363,802 1,159,981 1,144,176 Other Americas 20,362 16,037 65,773 36,403 Europe 8,683 11,454 29,835 40,713 Asia 8,988 11,711 27,376 33,386 Total real estate operations segment 460,715 403,004 1,282,965 1,254,678 Strategic capital segment: U.S. (1) 4,071 1,645 5,728 103,252 Other Americas 3,988 3,934 15,927 14,666 Europe 20,162 16,497 67,207 49,229 Asia 7,531 9,970 76,838 18,813 Total strategic capital segment 35,752 32,046 165,700 185,960 Total segment net operating income 496,467 435,050 1,448,665 1,440,638 Reconciling items: General and administrative expenses 62,244 57,656 182,287 171,350 Depreciation and amortization expenses 252,702 201,903 660,456 656,639 Operating income 181,521 175,491 605,922 612,649 Earnings from unconsolidated entities, net 56,634 55,066 181,839 172,267 Interest expense (64,186 ) (64,190 ) (166,761 ) (212,456 ) Interest and other income, net 1,891 4,816 9,508 9,493 Gains on dispositions of investments in real estate and revaluation of equity investments upon acquisition of a controlling interest, net 194,058 779,053 483,430 959,384 Foreign currency and derivative gains (losses), net 21,513 (18,872 ) 65,801 (46,327 ) Losses on early extinguishment of debt, net (1,955 ) - (2,657 ) (30,596 ) Earnings before income taxes $ 389,476 $ 931,364 $ 1,177,082 $ 1,464,414 September 30, 2018 December 31, 2017 Segment assets: Real estate operations segment: U.S. $ 27,633,382 $ 19,058,610 Other Americas 1,644,248 1,767,385 Europe 1,047,842 1,008,340 Asia 1,026,954 1,083,764 Total real estate operations segment 31,352,426 22,918,099 Strategic capital segment: U.S. 16,120 16,818 Europe 25,280 25,280 Asia 373 544 Total strategic capital segment 41,773 42,642 Total segment assets 31,394,199 22,960,741 Reconciling items: Investments in and advances to unconsolidated entities 5,618,178 5,496,450 Assets held for sale or contribution 761,575 342,060 Notes receivable backed by real estate - 34,260 Cash and cash equivalents 275,562 447,046 Other assets 218,648 200,518 Total reconciling items 6,873,963 6,520,334 Total assets $ 38,268,162 $ 29,481,075 (1) This includes compensation and personnel costs for employees who were located in the U.S. but also support other regions.

Supplemental Cash Flow Elements [Abstract]
Supplemental Cash Flow Information	NOTE 12. SUPPLEMENTAL CASH FLOW INFORMATION Our significant noncash investing and financing activities for the nine months ended September 30, 2018 and 2017 included the following: • We completed the DCT Transaction on August 22, 2018 for $8.5 billion through the issuance of equity and the assumption of debt. See Note 2 for more information on this transaction. • We capitalized $19.9 million and $20.8 million in 2018 and 2017, respectively, of equity-based compensation expense resulting from our development and leasing activities. • We received $232.2 million and $83.6 million in 2018 and 2017, respectively, of ownership interests in certain unconsolidated co-investment ventures as a portion of our proceeds from the contribution of properties to these entities, as disclosed in Note 3. • We formed a consolidated joint venture into which our partner contributed $11.8 million of land in 2018. • We issued 0.7 million shares in 2017 of the Parent’s common stock upon redemption of an equal number of common limited partnership units in the OP. • We contributed operating properties owned by NAIF to USLF in the third quarter of 2017. As a result, we received $1.1 billion of ownership interest in USLF as a portion of our proceeds from this contribution. In addition, USLF assumed the $19.5 million note receivable backed by real estate we received in the second quarter of 2017 and $956.0 million of secured mortgage debt. We paid $188.0 million and $232.4 million for interest, net of amounts capitalized, for the nine months ended September 30, 2018 and 2017, respectively. We paid $37.2 million and $29.7 million for income taxes, net of refunds, for the nine months ended September 30, 2018 and 2017, respectively.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation. The accompanying Consolidated Financial Statements are prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) and are presented in our reporting currency, the U.S. dollar. All material intercompany transactions with consolidated entities have been eliminated. The accompanying unaudited interim financial information has been prepared according to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and note disclosures normally included in our annual financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with such rules and regulations. Our management believes that the disclosures presented in these financial statements are adequate to make the information presented not misleading. In our opinion, all adjustments and eliminations, consisting only of normal recurring adjustments, necessary to present fairly the financial position and results of operations for both the Parent and the OP for the reported periods have been included. The results of operations for such interim periods are not necessarily indicative of the results for the full year. The accompanying unaudited interim financial information should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the SEC, and other public information.
New Accounting Pronouncements	New Accounting Pronouncements. New Accounting Standards Adopted Revenue Recognition . In May 2014, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update (“ASU”) that requires companies to use a five-step model to determine when to recognize revenue from customer contracts in an effort to increase consistency and comparability throughout global capital markets and across industries. In February 2017, the FASB issued an additional ASU that provides the accounting treatment for gains and losses from the derecognition of non-financial assets, including the accounting for partial sales of real estate properties. We adopted the revenue recognition and derecognition of non-financial assets standards (collectively “the new revenue recognition standard”) on January 1, 2018, on a modified retrospective basis. Rental revenues and recoveries earned from leasing our operating properties are excluded from this ASU and will be assessed with the adoption of the lease ASU discussed below. Our evaluation under the new revenue recognition standard included recurring and transactional fees and incentive fees (“promotes” or “promote revenues”) earned from our co-investment ventures as well as dispositions and contributions of real estate properties. There is no change in our recognition of recurring and transactional fees as we will continue to recognize these fees as we provide the services. Promote revenues are earned based on a venture’s cumulative returns over a certain time-period and the returns are determined by both the operating performance and real estate valuation of the venture, including highly variable inputs such as capitalization rates, market rents, interest rates and foreign currency exchange rates. As these key inputs are highly volatile and out of our control, and such volatility can materially impact our promotes period over period, we expect promote revenues will continue to be recognized at or near the end of the performance period. Accordingly, we do not expect significant changes in promote revenue recognition as a result of this ASU. For dispositions of real estate properties to third parties, the ASU will not impact the recognition of the sale. Beginning January 1, 2018, we recognized the entire gain attributed to contributions of real estate properties to unconsolidated co-investment ventures. We previously recognized a gain on contribution only to the extent of the third-party ownership in the unconsolidated co-investment venture acquiring the property and deferred the portion of the gain related to our ownership. We adopted the practical expedient to only assess the recognition of revenue for open contracts during the transition period and there was no adjustment to the opening balance of retained earnings at January 1, 2018. The comparative information has not been restated and continues to be reported under the accounting standards in effect for that period. New Accounting Standards Issued but not yet Adopted Leases. In February 2016, the FASB issued an ASU that provides the principles for the recognition, measurement, presentation and disclosure of leases. In July 2018, the FASB issued an additional ASU that provided for targeted improvements to the February 2016 ASU. We refer to both ASUs collectively as the new lease standard. • As a lessor. The accounting for lessors will remain largely unchanged from current GAAP; however, the new lease standard requires that lessors expense, on an as-incurred basis, certain initial direct costs that are not incremental in negotiating a lease. Under existing standards, these costs are capitalizable and therefore the new lease standard will result in certain of these costs being expensed as incurred after adoption. During the nine months ended September 30, 2018 and 2017, we capitalized $15.7 million and $17.9 million, respectively, of internal costs related to our leasing activities. The new lease standard provides lessors a practical expedient to not separate rental recovery revenue from the associated rental revenue if certain criteria are met. We assessed these criteria and concluded that the timing and pattern of transfer for rental recoveries and the associated rental revenue are the same and our leases will continue to qualify as operating leases under which we will recognize rental revenue, and therefore we will account for and present rental revenue and rental recovery revenue as a single component. • As a lessee. Under the new lease standard, lessees apply a dual approach, classifying leases as either finance or operating leases. A lessee is required to record a right-of-use (“ROU”) asset and a lease liability for all leases with a term of greater than 12 months, regardless of their lease classification. We are a lessee of ground leases and office space leases. At September 30, 2018 we had approximately 100 ground and office space leases that will require us to measure and record a ROU asset and a lease liability upon adoption. Details of our future minimum rental payments under ground and office space leases at December 31, 2017 are disclosed in Note 4 to the Annual Report on Form 10-K for the year ended December 31, 2017. The new lease standard is effective for us on January 1, 2019 and we will apply it prospectively. We expect to adopt the practical expedients available for implementation. By adopting these practical expedients, we will not be required to reassess the following and therefore we do not expect an adjustment to the opening balance of retained earnings: (i) whether an expired or existing contract meets the definition of a lease; (ii) the lease classification at the adoption date for existing leases; and (iii) whether costs previously capitalized as initial direct costs would continue to be amortized. This allows us to continue to account for our ground and office space leases as operating leases, however, any new or renewed ground leases may be classified as financing leases unless they meet certain conditions to be considered a lease involving land owned by a government unit or authority. The new lease standard will also require new disclosures within the accompanying notes to the Consolidated Financial Statements. We are completing our evaluation of the key drivers, such as the discount rate, in the measurement of the ROU asset and lease liability and the quantitative impact that adoption will have on the Consolidated Financial Statements in the future. Derivatives and Hedging . In August 2017, the FASB issued an ASU that simplifies the application of hedge accounting guidance in current GAAP and improves the reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its consolidated financial statements. Among the simplification updates, the ASU eliminates the requirement in current GAAP to separately recognize periodic hedge ineffectiveness. Mismatches between the changes in value of the hedged item and hedging instrument may still occur but they will no longer be separately reported. The ASU requires the presentation of the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. The ASU is effective for us on January 1, 2019. We do not expect the adoption of this ASU to have a material impact on the Consolidated Financial Statements.

(2) Prologis’ investment balance is presented at our adjusted basis derived from the ventures’ U.S. GAAP information. The difference between our ownership interest of a venture’s equity and our investment balance at September 30, 2018 and December 31, 2017, results principally from three types of transactions: (i) deferred gains from the contribution of property to a venture prior to January 1, 2018 ($648.1 million and $667.3 million, respectively); (ii) recording additional costs associated with our investment in the venture ($91.4 million and $94.2 million, respectively); and (iii) advances to a venture ($217.6 million and $210.0 million, respectively). For deferred gains from partial sales recorded prior to the adoption of the new revenue recognition standard, we will continue to recognize these gains over the lives of the underlying real estate properties or at the time of disposition to a third party. (3) Represents our weighted average ownership interest in all co-investment ventures based on each entity’s contribution of total assets, before depreciation, net of other liabilities.

We may also hedge our foreign currency risk by designating derivative financial instruments as net investment hedges, as these amounts offset the translation adjustments on the underlying net assets of our foreign investments. See Note 10 for more information about our nonderivative and derivative financial instruments. (3) Through the DCT Transaction, we assumed $1.9 billion of debt with a weighted average interest rate of 3.4%, which includes the noncash premium.

[1]	In October 2018, we and certain unconsolidated co-investment ventures sold a portfolio of operating buildings and land in Europe and the U.S in a single transaction. Included in the total assets of our unconsolidated co-investment ventures is $402.0 million of real estate assets that met the criteria to be classified as assets held for sale.
[2]	Prologis’ investment balance is presented at our adjusted basis derived from the ventures’ U.S. GAAP information. The difference between our ownership interest of a venture’s equity and our investment balance at September 30, 2018 and December 31, 2017, results principally from three types of transactions: (i) deferred gains from the contribution of property to a venture prior to January 1, 2018 ($648.1 million and $667.3 million, respectively); (ii) recording additional costs associated with our investment in the venture ($91.4 million and $94.2 million, respectively); and (iii) advances to a venture ($217.6 million and $210.0 million, respectively). For deferred gains from partial sales recorded prior to the adoption of the new revenue recognition standard, we will continue to recognize these gains over the lives of the underlying real estate properties or at the time of disposition to a third party.
[3]	Represents our weighted average ownership interest in all co-investment ventures based on each entity’s contribution of total assets, before depreciation, net of other liabilities.

[1]	During the nine months ended September 30, 2018, we entered into two interest rate swap contracts with an aggregated notional amount of €400.0 million ($499.7 million) to effectively fix the interest rate on our senior notes bearing a floating rate of Euribor plus 0.3% issued in January 2018.
[2]	During the nine months ended September 30, 2018, we repaid CAD 201.4 million ($158.9 million) on our 2015 Canadian Term Loan. At that time, we settled the interest rate swaps related to the 2015 Canadian Term Loan as we determined it was no longer probable that we would continue to have the future cash flows as originally hedged. As a result, the $12.5 million gain in Accumulated Other Comprehensive Income (Loss) “AOCI/L” at the time of settlement was reclassified to Interest Expense during the first quarter of 2018.
