Elon Musk has spent the past several months quietly assembling what some analysts are calling the world's first "orbital tech conglomerate." Now, a prediction market on Kalshi, the federally regulated U.S. exchange, is asking the natural next question: Will Tesla be next?
The market asks traders to predict when Tesla and SpaceX will merge, with contract windows ranging from mid-2026 to mid-2027. Over $42,000 has been wagered on the market, and traders aren't overly confident in a near-term deal, as the probability of a merger before March 1, 2027, currently sits at just 22%.

The Musk-Centric Consolidation That Already Happened
To understand why this market exists, you have to understand what's already taken place. In February 2026, SpaceX acquired xAI in what Musk described as the creation of "the most ambitious, vertically-integrated innovation engine on (and off) Earth," combining AI, rockets, space-based internet, and the X social media platform. The deal valued SpaceX at $1 trillion and xAI at $250 billion, making it the largest merger in history. Musk said the main rationale was to build "orbital data centers," AI infrastructure hosted in space, leveraging Starlink satellites as a computational backbone.
That deal made Tesla the obvious elephant in the room. When merger rumors first surfaced, there was speculation that Tesla could be included in a three-way combination, but it didn't happen, largely due to the fiduciary complications of merging a public company into a private one.
Why a Tesla-SpaceX Merger Is on the Table
Despite the complexity, the idea refuses to die. Musk himself has been signaling convergence for months, writing on X that his companies are "trending towards convergence." Since then, Tesla poured $2 billion into xAI, SpaceX merged with xAI, and Musk increasingly speaks of his companies not as separate entities but as pieces of the same technological stack.
The synergies are tangible. Optimus robots could assemble Starship vehicles, while Starlink satellite connectivity could enhance Tesla's Robotaxi network and Full Self-Driving updates. Tesla's stock also needs a story. After gains of 102% in 2023 and 63% in 2024, Tesla returned just 11% in 2025, less than the S&P 500, and is down nearly 15% in 2026. A merger with the rocket company investors love could reframe the narrative entirely.
Wedbush analysts have said there is a "growing chance that Tesla will eventually be merged in some form into SpaceX/xAI," arguing that combining the two could be Musk's "holy grail" over the next 12 to 18 months.
The Bear Case
Not everyone is convinced, and the Kalshi odds reflect that skepticism. Tesla is a public company with fiduciary duties to its shareholders, and any merger would require Musk to fairly value both sides of the deal, while leading negotiations on both sides himself. Critics have drawn comparisons to the controversial 2016 SolarCity acquisition and Tesla's contentious $2 billion xAI investment, both of which sparked shareholder lawsuits.
The ownership structure also creates asymmetric incentives: Musk owns roughly 43% of SpaceX, but only about 13% of Tesla, meaning any deal's terms would face intense scrutiny from Tesla's public shareholders.
Why Traders Love This Market
Prediction markets like Kalshi have increasingly become what some call a real-time "B.S. detector" aggregating the views of engineers, data scientists, and insiders willing to put money behind their convictions.
For traders, this contract offers asymmetric upside: a surprise announcement or a well-timed Musk post on X could move those 22% odds dramatically overnight. In a world where Musk's empire is already visibly consolidating, trading on when it happens next may be more interesting than trading on whether it does.
