Kalshi traders slash Musk's OpenAI win odds to 37% from 59% ahead of Monday ruling

Published May 4, 2026

Traders on Kalshi have slashed the odds of Elon Musk winning his lawsuit against OpenAI, with the contract price tumbling from roughly 59% to 37% ahead of an expected Monday morning ruling. The prediction market movement reflects growing skepticism toward Musk's legal challenge to the artificial intelligence company he co-founded. The sharp drop followed new court filings, though the specific contents of those filings were not detailed. The contract had stood at 58.9% before the decline, according to platform data. The case represents Musk's ongoing battle against the company, which has evolved from a nonprofit research lab into a closely watched AI powerhouse valued in the tens of billions.

Why this matters?

Kalshi's OpenAI lawsuit contract is one of the platform's highest-profile legal-event markets, and a 22-point swing in a single weekend signals that informed traders are aggressively repricing based on sealed or late-breaking filings—suggesting the market maker may need to tighten circuit-breakers on litigation contracts that move faster than public disclosure allows.
