The reason for the forced departure of former OpenAI CEO Sam Altman is unclear, but users of decentralized prediction platform Polymarket are betting on it, CoinDesk reported. Currently, the most liquid market asks users to predict whether Altman will return to the CEO role before the end of the year. While the "yes" share traded at 10 cents, representing a 10% chance, that changed after Bloomberg reported on Sunday US time that former Twitch boss Emmet Shear had been appointed to the role. Another contract asks if Altman will be criminally charged by Nov. 30, with a "yes" currently trading at 1 cent. On Sunday, eight forecast contracts had liquidity in excess of $250,000.
