Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | Note 1—Description of Organization, Business Operations and Basis of Presentation dMY Technology Group, Inc. (the “Company”) was incorporated in Delaware on September 27, 2019. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). Although the Company is not limited to a particular industry or sector for purposes of consummating a Business Combination, the Company intends to focus its search for an initial business combination on companies within the mobile application (“app”) ecosystem or consumer internet companies with enterprise valuations in the range of $500 million to $1.5 billion, though the Company’s search may span many consumer software segments worldwide. The Company is an emerging growth company and, as such, the Company is subject to all of the risks associated with emerging growth companies. As of June 30, 2020, the Company had not commenced any operations. All activity for the period from September 27, 2019 (inception) through June 30, 2020 relates to the Company’s formation and the initial public offering (the “Initial Public Offering”) described below, and since the closing of the Initial Public Offering, the search for a prospective initial Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income The Company’s sponsor is dMY Sponsor, LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on February 20, 2020. On February 25, 2020, the Company consummated its Initial Public Offering of 23,000,000 units (the “Units” and, with respect to the Class A common stock included in the Units being offered, the “Public Shares”), including the issuance of 3,000,000 Units as a result of the underwriters’ exercise of their over-allotment option in full (the “Over-Allotment Units”), at $10.00 per Unit, generating gross proceeds of $230.0 million, and incurring offering costs of approximately $13.2 million, inclusive of $8.05 million in deferred underwriting commissions (Note 5). Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 6,600,000 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) at a price of $1.00 per Private Placement Warrant in a private placement to the Sponsor, generating proceeds of $6.6 million (Note 4). Upon the closing of the Initial Public Offering and the Private Placement, $230.0 million ($10.00 per Unit) of the net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement was placed in a trust account (the “Trust Account”) located in the United States at JP Morgan Chase Bank, N.A. with Continental Stock Transfer & Trust Company acting as trustee, and invested only in U.S. “government securities,” within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or in money market funds meeting the conditions of paragraphs (d)(2), (d)(3) and (d)(4) of Rule 2a-7 The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the net assets held in the Trust Account (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in Trust) at the time of the agreement to enter into the initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act 1940, as amended (the “Investment Company Act”). The Company will provide holders of the Company’s outstanding shares of Class A common stock, par value $0.0001 per share, sold in the Initial Public Offering (the “Public Stockholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then held in the Trust Account (initially anticipated to be $10.00 per Public Share). The per-share amount to be distributed The Certificate of Incorporation will provide that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 20% or more of the Public Shares, without the prior consent of the Company. The Sponsor and the Company’s officers and directors (the “initial stockholders”) have agreed not to propose an amendment to the Certificate of Incorporation to modify the substance or timing of the Company’s obligation to redeem 100% of the Public Shares if the Company does not complete a Business Combination within the Combination Period (as defined below) or with respect to any other material provisions relating to stockholders’ rights or pre-initial Business Combination activity, If the Company is unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering, or February 25, 2022 (the “Combination Period”), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, The initial stockholders have agreed to waive their rights to liquidating distributions from the Trust Account with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the initial stockholders acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to the deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a Business Combination within in the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00. In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party (except for the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a letter of intent, confidentiality or other similar agreement or business combination agreement (a “Target”), reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or Target that executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) not will it apply to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. On July 27, 2020, the Company entered into a Business Combination Agreement with Rush Street Interactive, LP, a Delaware limited partnership, the sellers set forth on the signatures pages thereto, the Sponsor, and Rush Street Interactive GP, LLC, a Delaware limited liability company, in its capacity as the sellers’ representative. Basis of Presentation The accompanying unaudited condensed financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, the unaudited condensed financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the periods presented. Operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected through December 31, 2020. The accompanying unaudited condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the final prospectus and the Form 8-K filed Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging This may make comparison of the Company’s financial statements with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Liquidity As of June 30, 2020, the Company had approximately $965,000 in its operating bank account, working capital of approximately $603,000, and approximately $641,000 of interest income available in the Trust Account for the Company’s tax obligations, if any. The Company’s liquidity needs to date have been satisfied through a $25,000 contribution from the Sponsor in exchange for the issuance of the Founder Shares to the Sponsor, the Note (as defined below) of approximately $90,000 from the Sponsor, and the proceeds from the consummation of the Private Placement not held in the Trust Account. On March 19, 2020, the Company repaid the Note (as defined below) in full to the Sponsor. In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, provide the Company Working Capital Loans (see Note 4). As of June 30, 2020, there were no amounts outstanding under any Working Capital Loan. Management continues to evaluate the impact of the COVID-19 pandemic Based on the foregoing, management believes that the Company will have sufficient working capital and borrowing capacity from the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors to meet its needs through the earlier of the consummation of a Business Combination or one year from this filing. Over this time period, the Company will be using these funds for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination. |
