Over in an Oakland courtroom Elon Musk’s lawsuit against OpenAI is mid-trial, and Kalshi traders have been repricing the outcome day by day. The Kalshi contract has a January 2027 deadline for a Musk win with current pricing around 41% to 42% Yes. What started off looking like sweeping betrayal has changed plenty since the early filings, with the original fraud claim being dismissed pre-trial leaving breach of charitable trust and unjust enrichment as the only questions.
Elon Musk V OpenAI Recent Court Performance
On the trial side the legal terrain has shifted away from the early filings, in ways that favor OpenAI over Musk.
Fraud Claims Are Gone
Pre-trial saw the fraud allegations dropped, taking out the broadest part of Musk’s original argument. Charitable trust and unjust enrichment is what the legal team has to build everything around now.
What Musk Is Still Asking For
The remedies he wants are massive. Leadership changes at OpenAI, a return toward nonprofit governance and around $150 billion in damages from OpenAI and Microsoft with proceeds going to OpenAI’s charitable arm.
Key Factors That Could Drive a Musk Win
A couple of threads from testimony give the “Yes” side some ammunition on prediction markets.
The Unjust Enrichment Angle
Brockman’s stake in OpenAI, as per disclosures, is sitting close to $30 billion. Musk’s lawyers have raised issues with financial ties between Brockman and Sam Altman. Personal benefit by leadership off a structure built on nonprofit credibility and public trust is now the main argument.
Governance Testimony From Mira Murati
Altman came across as deceptive at times in Murati’s description and she said he created distrust among executives. That handed Musk’s team some useful material.
Factors That Could Prevent a Musk Win
OpenAI’s defence has lined up clear pillars that all aim at Musk’s credibility too.
Musk’s Own For-profit Record
OpenAI’s strongest card here is Musk himself, who supported a for-profit model back in 2017. He was on board with it right up until he walked away, then he sued.
The xAI Rivalry Problem
xAI sits behind a lot of the defence narrative as well. Musk runs the OpenAI competitor today, so the lawsuit gets painted as competitive positioning by the defence rather than a principled nonprofit stand.
What Analysts and Forecast Models Are Saying
Most politics prediction sites are reading this as uphill for Musk now fraud is out the window. Kalshi traders seem to agree with that, pricing him at roughly 41% to 42% Yes.
How to Trade This Question at Kalshi
Yes is the side to take if you think the court sides with Musk before January 1, 2027. No is the side to take if you think that won’t happen by the deadline.
| Outcome | Chance | Yes price | No price |
|---|---|---|---|
| Elon Musk wins case against OpenAI before 2027 | 41%–42% | 41c–42c | 59c–61c |
The Jury Will Decide
Musk has enough left to keep the case alive, especially around governance and the financial incentives at the top of OpenAI. Fraud is now gone though and OpenAI can point right back at Musk’s own history with the for-profit argument. Click the banners on this page to check the latest prices on Kalshi.
