Market Description

Investor Bill Ackman proposed on X that Elon Musk take SpaceX public through a merger with Pershing Square SPARC Holdings Ltd., a company founded and run by Ackman to innovatively transact public offerings through the use of Special Purpose Acquisition Rights or “SPARs” (see: https://x.com/BillAckman/status/2002484983123136990). This market will resolve to “Yes” if either of the following conditions are met: - An agreed merger or business combination deal between SpaceX and Pershing Square SPARC Holdings Ltd. is officially announced by December 31, 2026, 11:59 PM ET. - An offering of “SPARs” to Tesla Shareholders or other individuals which represent a subscription warrant to purchase shares in a business combination of Pershing Square SPARC Holdings Ltd. and SpaceX is officially announced by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. An official announcement of an agreed merger/combination of these two companies or a SPAR offering of subscription warrants to purchase shares in a combination of these companies will be sufficient to resolve this market, regardless of when the merger or SPAR offering actually occurs. If SpaceX goes public through another means, (i.e. SpaceX IPOs through a typical listing of their shares on a public stock exchange), this market will resolve immediately to “No” The primary resolution source for this market will be official company communications and/or regulatory filings from SpaceX and Pershing Square SPARC Holdings Ltd.; however, a consensus of credible reporting may also be used.
