Odds of a merger happening before March jumped to 56% by Friday morning, up from 29%. Odds for an integration before April and May climbed to similar levels.
The contract asks, "When will Tesla and SpaceX merge?" and will be verified by news outlets and the Securities and Exchange Commission's EDGAR database.
Tesla, known for its electric vehicles, and SpaceX, a rocket and satellite company, have collaborated before. Both are controlled by Elon Musk.
On Thursday, Tesla showed off its long-delayed Roadster, which relies on SpaceX technology to make the vehicle hover. A video showcasing the Roadster's capabilities was also recorded from SpaceX's test site in Texas.
Beyond collaboration, the growing speculation of a merger comes after Musk spoke of "more and more overlap" between Tesla and SpaceX on the EV maker's latest earnings call.
Barclays now expects a merger could be announced before Tesla's annual general meeting, which must take place no later than Dec. 6, 2026. Analyst Dan Levy expects the merger may be proposed as an AI vertical integration, involving Tesla's Robotaxi and Optimus with SpaceX's Grok and Macrohard.
Terafab, the semiconductor project relying on Tesla, SpaceX and xAI, could also be a "key driver" for the merger, Levy added.
"Notably, while we suspect there would be some financial synergies, the true value would be in vertical integration," Levy said.
Earlier Friday, Evercore ISI recommended buying SpaceX shares ahead of its next scheduled earnings release, set for early November, and boosted its 12-month price target on the stock by 20% to $275.
