OpenAI terminated an employee for using nonpublic company information to trade on external prediction markets like Polymarket.

The company stated that using confidential data for personal gain directly violates internal policies.

Fidji Simo, OpenAI’s CEO of Applications, reportedly disclosed the firing internally.

This incident marks one of the first known corporate actions of its kind in the technology industry.

Trading on prediction markets using insider knowledge currently occupies a regulatory gray area.

The company has not revealed the employee's identity or the specific trades involved.

This action sets a precedent for how AI companies manage proprietary information on emerging financial platforms.
