Musk's OpenAI lawsuit odds slide 8 points after day one of testimony on Kalshi

Updated 28d ago

Elon Musk's odds of winning his lawsuit against Sam Altman's OpenAI dropped to 53.5% on the Kalshi prediction market following his first day of testimony, an 8-point decline. The contract ranks as the second-highest volume event among all live contracts related to Musk, drawing significant trader interest. Market pricing implies a low probability of Musk prevailing in the case. The lawsuit, which has attracted substantial attention from prediction market participants, saw its contract price move sharply downward after the initial courtroom proceedings began. Kalshi traders are actively pricing in the legal developments as Musk presents his arguments in the case he brought against the artificial intelligence company he co-founded.

Why this matters?

Kalshi traders now price Musk's victory below a coin flip, eroding the premium his celebrity status typically commands in political and legal markets — a signal that could chill similar high-profile litigation contracts if day-two testimony confirms today's downward trajectory.
