Trader consensus on Polymarket reflects near-certain 96.2% implied probability for "No" on SpaceX pursuing an initial public offering via Bill Ackman's proposed SPAR vehicle, driven by Elon Musk's repeated public dismissals of near-term IPO plans and the absence of any official announcements, filings, or confirmed discussions between the parties. Ackman's SPAR—a novel "special purpose acquisition rights" structure pitched as a flexible alternative to SPACs—has garnered media attention but no adoption from SpaceX, which continues raising massive private funding rounds at soaring valuations amid Starship development milestones. Recent Starship test flight progress reinforces Musk's stance that public listing awaits full operational reusability. Realistic wildcards include unexpected Musk pivots, regulatory greenlights for SPAR, or Starlink spin-off shifts, though traders price these as low-probability tail risks with resolution approaching without catalysts.

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.Trader consensus on Polymarket reflects near-certain 96.2% implied probability for "No" on SpaceX pursuing an initial public offering via Bill Ackman's proposed SPAR vehicle, driven by Elon Musk's repeated public dismissals of near-term IPO plans and the absence of any official announcements, filings, or confirmed discussions between the parties.
