Polymarket traders push Claude Mythos release odds to 74% for June 10
Polymarket traders priced a 74% probability that Anthropic's Claude Mythos model would be released on June 10 as of June 9, according to market data on the platform. The implied odds jumped 24 percentage points over the prior 24 hours. Polymarket listed a live market titled Claude Mythos released on…? with the June 10 date rapidly tightening into favor. No trading volume or liquidity figures were published by the platform. The pricing shift comes amid heightened speculative attention to Anthropic's release schedule, with traders adjusting positions ahead of the stated date without additional confirmation from the AI lab.
The sharp single-day repricing gives any trader who took the long side at 50% a near-50% return in 24 hours, but with no disclosed volume or liquidity, outsiders cannot tell whether the move reflects genuine information flow or thin-market manipulation.
Joins a recent flurry of AI model launch markets on Polymarket and Kalshi, as both venues race to list event contracts on Anthropic and OpenAI product timelines while building institutional pipelines for the category.
