Predicting market insider trading scandal exposure, OpenAI takes the lead in dismissing involved employees

OpenAI has dismissed an employee due to suspected insider trading on prediction market platforms such as Polymarket and Kalshi, where they allegedly used internal confidential company information to bet on related contracts. The dismissal was disclosed in an internal email by Fidji Simo, CEO of the Applications division, stating that company policy prohibits employees from using confidential information for personal gain.

OpenAI Dismissal Incident: Policy Boundaries Revealed in Internal Email

OpenAI did not disclose the employee’s name or specific transaction details, but Fidji Simo’s internal email clearly states that the employee used company confidential information to trade on external prediction markets like Polymarket. Spokesperson Kayla Wood’s public statement further confirmed that such behavior violates OpenAI’s existing compliance policies, regardless of profit or loss.

It is noteworthy that Polymarket operates on the Polygon blockchain, where transaction ledgers are anonymous but traceable, making on-chain investigations possible.

Key Points of the OpenAI Insider Trading Incident

• Involved Behavior: Employee used non-public internal information from OpenAI to bet on related event contracts on prediction markets like Polymarket and Kalshi.
• Disclosure Method: CEO Fidji Simo proactively informed all employees via internal email.
• Policy Basis: OpenAI’s current compliance policies explicitly prohibit employees from using confidential company information for personal benefit.
• Industry First: This is the first recorded case of a major tech company dismissing an employee for insider trading on prediction markets.

On-Chain Data from Polymarket Reveals Suspicious Transactions Involving Multiple Parties

Blockchain analysis platform Unusual Whales shows that suspicious transactions related to OpenAI topics have formed multiple clusters since March 2023. A total of 77 suspected insider trading positions across 60 wallets have been identified, based on account creation time, transaction history, and investment amounts.

Suspicious activity mainly occurred around the launch of products like Sora, GPT-5, ChatGPT Browser, and issues concerning CEO Sam Altman’s departure. A notable case involved a new wallet betting on Altman’s return two days after his dismissal in November 2023, ultimately earning over $16,000. This account has not placed any further bets since.

Unusual Whales CEO Matt Saincome stated: “Within 40 hours before OpenAI released the browser, 13 new wallets with zero prior transaction history appeared, collectively betting $309,486 and all correctly predicting the outcome. Seeing so many new wallets making the same bets simultaneously raises suspicions of insider information being leaked.”

On a broader regulatory level, Kalshi has reported multiple suspicious insider trading cases to the U.S. Commodity Futures Trading Commission (CFTC): a staff member of YouTuber Mr. Beast was suspended for two years and fined $20,000; right-wing candidate Kyle Langford was blocked for betting on his own campaign. Tech giants like Google, Meta, and NVIDIA have not responded to Wired’s inquiries about their prediction market trading policies, and Polymarket has not commented on this matter.
