Warrants and Rights Note Disclosure [Abstract]
Private Placement Warrants and Unvested Founder Shares	Private Placement Warrants and Unvested Founder Shares Warrants were issued to Churchill Sponsor III, LLC ("Sponsor") (the "Private Placement Warrants") in a private placement simultaneously with the closing of the initial public offering by Churchill Capital Corporation III ("Churchill") which closed on February 19, 2020, which include the warrants to purchase Churchill's Class A common stock ("Working Capital Warrants") issued pursuant to the terms of an unsecured promissory note issued by the Company to the Sponsor, and which are on terms identical to the terms of the Private Placement Warrants. On July 12, 2020, Churchill entered into the Merger Agreement (the "Merger Agreement") by and among Music Merger Sub I, Inc., Music Merger Sub II, LLC, Holdings, and Polaris Parent Corp. In connection with the execution of the Merger Agreement, Churchill and Michael Klein, Jay Taragin, Jeremy Paul Abson, Glenn R. August, Mark Klein, Malcolm S. McDermid, and Karen G. Mills entered into a Sponsor Agreement (as amended, the "Sponsor Agreement"). Pursuant to the terms of the Sponsor Agreement, 310,102 of the founder shares ("Unvested Founder Shares") and 120,000 Private Placement Warrants were unvested as of October 8, 2020 and will re-vest at such time as, during the period starting on October 8, 2021 and ended on October 8, 2025, the closing price of our Class A common stock exceeds $500.00 per share for any forty (40) trading days in a sixty (60) consecutive day period. Such founder shares and Private Placement Warrants that do not re-vest on or before October 8, 2025 will be forfeited and cancelled. The 120,000 Private Placement Warrants that unvested are not transferable, assignable or salable (except to our officers and directors and other persons or entities affiliated with the Sponsor and other permitted transferees, each of whom will be subject to the same transfer restrictions) until they re-vest. The Private Placement Warrants and Unvested Founder Shares were initially recorded at fair value on the date of consummation of the Merger and the other transactions contemplated by the Merger Agreement and the related agreements (the "Transactions") and are subsequently adjusted to fair value at each subsequent reporting date. The fair value of the Unvested Founder Shares and unvested Private Placement Warrants is obtained using a Monte Carlo model and the fair value of the remaining Private Placement Warrants is obtained using a Black-Scholes model, together referenced as the "option pricing" model. The Company will continue to adjust the liability for changes in fair value for the founder shares until the earlier of the re-vesting or forfeiture of these instruments. The Company will continue to adjust the liability for changes in fair value for the Private Placement Warrants until the warrant is equity classified. There were 476,717 Private Placement Warrants and 310,102 Unvested Founder Shares outstanding as of December 31, 2024 and September 30, 2025. As of September 30, 2025 and December 31, 2024, the Private Placement Warrants and the Unvested Founder Shares had no value. On October 8, 2025, the Private Placement Warrants and the Unvested Founder Shares were forfeited and cancelled in accordance with the terms of the Sponsor Agreement.
