A Google employee is under scrutiny after reportedly earning $1 million in a single day on Polymarket by betting on outcomes tied to the company’s own products and search trends. The trader went 22-for-23 on positions after Google briefly published internal search results early, revealing data that matched his wagers before being removed. His total open positions allegedly swelled to nearly $3.9 million.

The individual had previously drawn attention for making more than $150,000 by correctly predicting the early release timing of Gemini 3.0. After suspicions surfaced, he attempted to switch identities on the platform, but users quickly linked the accounts through trading behavior and betting patterns.

The incident raises new concerns about the potential for insider activity in prediction markets, which have seen rapid growth as crypto-driven platforms attract sophisticated traders and real-time event speculation.
