An employee was terminated for allegedly using confidential company information to trade on prediction markets, including Polymarket, violating internal policies against insider trading for personal gain. The incident follows a similar case where Kalshi, a regulated prediction market, fined and banned a MrBeast editor for alleged insider trading, highlighting growing scrutiny of these platforms. Prediction markets allow bets on real-world events, such as OpenAI’s future product announcements or IPO timing, with significant financial stakes—like a recent $470,300 win on Kalshi. OpenAI’s policy explicitly prohibits employees from leveraging non-public data for financial advantage, reinforcing ethical boundaries amid rising interest in speculative trading platforms. The company declined further comment, but the firing underscores broader concerns about insider trading risks in emerging fintech markets.

In Brief Posted: 3:00 PM PST · February 27, 2026 Image Credits:Bryce Durbin / TechCrunch Julie Bort OpenAI fires employee for using confidential info on prediction markets OpenAI has fired an employee over the employee’s activity on prediction markets, including Polymarket, the company confirmed to Wired. The employee used confidential OpenAI information in connection with the trades made, the company alleges. OpenAI didn’t release the name of the employee. However, a spokesperson said that such actions violated a company policy that bans workers from using inside information for personal gain, including on prediction markets. Prediction markets like Polymarket and Kalshi allow people to make wagers on the outcomes of real-world events. For instance, on Polymarket, there are wagers being made around the kind of products OpenAI will announce in 2026 and when the company will go public. They can cover any event, and some eye-popping money can be made. As we recently reported, an accountant won a $470,300 jackpot on Kalshi by betting against DOGE believers. Prediction markets insist they are not gambling sites, preferring to label themselves as financial platforms. Kalshi is a regulated exchange and, in fact, it fined and banned a MrBeast editor for similar alleged insider trading earlier this week. OpenAI did not immediately respond to a request for additional comment.
