On April 1, 2026, Elon Musk’s aerospace venture SpaceX submitted confidential paperwork for a public market debut. The anticipated capital raise of $75 billion would dwarf Saudi Aramco’s record-setting $29 billion offering from 2019. Industry watchers project SpaceX could command a valuation approaching $2 trillion upon listing, positioning it among America’s most valuable publicly traded enterprises.

Yet the initial public offering may represent just the opening chapter. Financial analysts and institutional investors are actively discussing whether Musk intends to combine SpaceX with Tesla, forming a corporate behemoth valued north of $3.5 trillion. Such a transaction would shatter all previous merger records.

Musk has embraced the term “convergence” when discussing his vision for unifying his various business interests. While he hasn’t publicly acknowledged formal merger negotiations, his recent strategic moves have intensified marketplace speculation.

During February 2026, SpaceX finalized its combination with xAI, Musk’s artificial intelligence venture, establishing a combined valuation of $1.25 trillion. Subsequently, Tesla disclosed a $2 billion capital injection into xAI, securing an ownership position in SpaceX. Musk additionally unveiled plans for Terafab, a collaborative semiconductor manufacturing facility, alongside Digital Optimus, a cooperative AI agent initiative, further intertwining Tesla and SpaceX operational frameworks.

The SpaceX Value Proposition

SpaceX now commands over half of global orbital launch activity. Its Starlink satellite internet service reached nine million paying customers by year-end 2025, representing approximately 100% annual growth, with each subscriber generating at least $600 in yearly revenue.

Musk’s ambitious long-range strategy centers on orbital data processing facilities. He projects these space-based computing centers could operate more cost-effectively than terrestrial alternatives within a two-to-three-year timeframe. Success in this arena would position SpaceX to capture market share in a computing sector currently exceeding $60 billion annually, based on OpenAI’s present expenditure levels.

SpaceX’s reusable Falcon 9 launch system already achieves an estimated $2,000 to $3,000 cost per kilogram for low Earth orbit deployment. The upcoming Starship vehicle promises to reduce these expenses by an additional 80% to 90%.

Greg Martin, managing director at Rainmaker Securities, calculates that SpaceX maintained Ebitda profit margins approaching 50% prior to the xAI combination.

Tesla’s Current Headwinds

Tesla stock has declined more than 22% during 2026 and currently trades near September 2025 lows. Ryan Brinkman, JP Morgan’s automotive analyst, maintains an Underweight recommendation with a $145 price objective, representing approximately 58% downside from current levels.

Tesla’s first quarter 2026 deliveries totaled 360,000 units, significantly missing earlier Wall Street projections. Musk had committed to deploying autonomous taxi services across nine metropolitan areas during the first half of 2026, yet operations remain limited to Austin, Texas.

Skepticism about the merger concept remains widespread. Gary Black, co-founder of Future Fund, contends Tesla shareholders would contribute approximately 55% of combined earnings while receiving only 40% of equity in the merged entity. Columbia Law Professor Dorothy Lund highlights that any transaction would necessitate shareholder approval and likely face regulatory antitrust examination.
