While Tesla shares reached new heights at the end of last year, a spectacular offer from billionaire Bill Ackman is causing a stir.
• Bill Ackman proposes merging SpaceX with Pershing Square SPARC Holdings
• Tesla shareholders should receive 0.5 subscription rights (SPARs) per share
• Proposal also includes an option for future shares in Musk’s AI company xAI for all investors who exercise their SpaceX rights
SPARC Model: A “Democratization” of the IPO Process?
Investor Bill Ackman suggested an unconventional path for SpaceX’s long-awaited IPO via X (formerly Twitter) in December. Instead of a classic IPO with high fees for investment banks, the SPARC structure (Special Purpose Acquisition Rights Company) developed by his company Pershing Square will be used.
.@elonmuskwhat if we took @SpaceX public by merging it with Pershing Square SPARC Holdings, Ltd. (SPARC) a new form of acquisition company that was approved by the @SECGov.
We could distribute SPARC special purpose acquisition rights (SPARs) to @Tesla shareholders so that all…

What’s special: The subscription rights (SPARs) would be issued directly to Tesla shareholders. Ackman justifies this by complying with Elon Musk’s desire to have loyal supporters involved in SpaceX. “This would reward Tesla shareholders and completely democratize the IPO process,” Ackman said. The structure does not require founder shares or warrants for sponsors and is based 100 percent on common shares.
Billions in capital for the Mars mission
The financial clout of the proposal is enormous. Depending on the exercise price of the rights, SpaceX could raise massive capital: at a price of $11.03 per SPAR, SpaceX would generate approximately $42 billion, while at a set price of $42.00, revenues could even rise to as much as $148.7 billion, Ackman calculates. Additionally, Pershing Square has committed to contributing $4 billion in equity regardless of valuation. The timeline for this effort is ambitious, with Ackman aiming for due diligence within 45 days and an official announcement of the deal by mid-February 2026.
Impact on Tesla and the space sector
The news is of great importance for Tesla investors in two ways. On the one hand, the market already reacted euphorically to the IPO speculation, which drove Tesla shares to a new all-time high of $498.83 on December 22nd. Analysts like Dan Ives from Wedbush see the close integration of the Musk companies as a potential “super ecosystem” that could gain massive value through such synergies. On the other hand, Bill Ackman’s specific proposal offers Tesla shareholders an exclusive and direct economic advantage when purchasing SpaceX shares through the allocation of subscription rights, even before the company is officially listed. An IPO of this size – with a potential valuation of up to $1.5 trillion – would also support the entire space sector, as recent price gains in industry peers such as Rocket Lab and EchoStar underline.
