OpenAI fires employee over prediction market trading

OpenAI has fired an employee for using confidential info on prediction markets, a move that the artificial intelligence company confirmed to Wired. According to allegations from OpenAI, the unnamed employee used confidential company information in connection with trades made on these speculative platforms, which include Polymarket. Although OpenAI did not release the specific identity of the employee, a company spokesperson stated that the individual’s actions violated an internal policy. This policy explicitly bans workers from using inside information for personal gain, including on prediction markets.

The incident underscores the rising prominence of prediction markets, which are platforms allowing wagers on real-world events. These platforms, such as Polymarket and Kalshi, have increasingly positioned themselves as financial platforms rather than gambling sites. The scope of these wagers often directly targets corporate developments; on Polymarket, for example, users are actively making wagers around the specific types of products OpenAI will announce in 2026, as well as the timeline for when the company will go public. Because these platforms allow users to bet on highly specific corporate milestones, they create financial incentives for employees with access to non-public information. These speculative environments can involve significant financial sums, as demonstrated by a recent $470,300 jackpot won by an accountant on Kalshi who bet against DOGE believers.

As these platforms attract larger volumes of capital, they are facing increased pressure to maintain market integrity and police potential insider trading. Kalshi, which operates as a regulated prediction market exchange, recently fined and banned an editor for the content creator MrBeast for similar alleged insider trading. The enforcement actions by both corporations and regulated exchanges indicate a tightening of oversight as prediction markets transition into mainstream financial instruments. This regulatory action, combined with OpenAI’s recent termination, highlights the growing tension between corporate confidentiality and the rise of high-stakes betting on corporate secrets. OpenAI did not immediately respond to a request for additional comment.
