� OpenAI fires employee over insider trading on Polymarket

OpenAI dismissed an employee for insider trading tied to bets on Polymarket. It appears to be the first confirmed big tech firing linked to prediction markets.

Before the launch of the ChatGPT browser, 13 new Polymarket accounts appeared 40 hours ahead of release.

Together they placed $300k on the correct outcome and reportedly made a strong return.

A similar case happened in 2023 during Sam Altman’s removal, when a new trader bet on his comeback and earned $16k before disappearing.

Insider concerns around product launch dates had been building. Prediction markets are starting to test corporate information control.
