SpaceX IPO Sparks Fresh Speculation of a Tesla Merger
5/23/2026, 11:12:33 AM
The IPO Filing and Merger Outlook
SpaceX submitted an S-1 registration statement on Wednesday, marking the largest initial public offering in U.S. market history. Wedbush Securities analyst Dan Ives immediately noted that the filing “lays the groundwork” for a possible combination with Tesla in 2027. Ives estimates the odds of a merger at roughly 80 % and projects a post-IPO valuation for SpaceX of up to $2 trillion, which would push a combined entity above $3 trillion when added to Tesla’s $1.31 trillion market capitalization.
Historical Ties and Joint Ventures
The two Musk-led firms have deepening operational links. In early 2024 Tesla’s $2 billion investment in xAI was converted into SpaceX shares after SpaceX acquired xAI, creating a stake of less than 1 % of SpaceX’s expected valuation. A joint “Terafab” facility, announced in March, will produce AI chips for Tesla’s robotaxis and humanoid robots, while SpaceX plans V3 satellites in late 2026 and solar-powered AI compute satellites by 2028. These projects integrate satellite connectivity, AI platforms, and manufacturing scale across the two companies.
Key Players
- Elon Musk – CEO, CTO, and chairman of SpaceX; CEO of Tesla.
- Dan Ives – Managing Director, Wedbush Securities, author of the merger analysis.
- Wedbush Securities – Research firm providing the 80 % merger probability.
- Tesla, Inc. – Automotive and energy company.
- SpaceX – Aerospace and satellite services company.
- xAI – Musk’s artificial-intelligence startup now part of SpaceX.
Valuation and Market Metrics
- SpaceX IPO target valuation: up to $2 trillion.
- Tesla market cap: $1.31 trillion.
- Combined potential value: > $3 trillion.
- Total addressable market for SpaceX’s AI-enabled services: $28.5 trillion, with $22.7 trillion in enterprise applications.
- Kalshi platform odds: 33 % for a merger before May 2027, down from 77 % for a pre-April 2027 deal.
Strategic Rationale
Ives frames the merger as a move to control a larger share of the AI ecosystem. SpaceX contributes satellite infrastructure and the Grok platform from xAI, while Tesla offers manufacturing scale, vehicle data, and robotics. The combined entity could align AI compute, energy storage, and space-based connectivity under a single corporate structure.
Official Positions
Musk has stated that any intercompany transaction would require approval from both Tesla and SpaceX boards and must protect the interests of each company’s shareholders. The S-1 filing confirms Musk will retain majority voting power after the IPO, preserving his control over SpaceX.
Criticism and Market Concerns
Analysts warn that a merger could intensify market concentration, leading to index overweighting and governance complexity. Critics also note that Tesla faces heightened competition in China from BYD, Geely, and Chery, and that a combined entity might distract from core operations.
Conflicting Forecasts
While Wedbush cites an 80 % probability of a merger, market-based odds on Kalshi have fallen to 33 %, indicating divergent expectations among investors and analysts. No formal announcement from either company has yet confirmed merger intentions.

Outlook
The next catalyst will be SpaceX’s IPO pricing and any formal signal from either board regarding a merger. Investors will watch for regulatory filings, board approvals, and updates on the Terafab project as indicators of whether the two Musk-led enterprises will ultimately consolidate.
