Google engineer charged with insider trading after $1.2M gain on Polymarket

A Google engineer has been charged with insider trading after allegedly earning $1.2 million on the prediction market platform Polymarket, according to TechCrunch.

According to the complaint, the engineer risked more than $2.7 million on wagers related to Google's 2025 Year in Search campaign. Prosecutors allege the engineer used non-public information about the campaign's content to place the bets.

The case marks a novel application of insider-trading law to prediction markets, which have grown significantly in prominence. Polymarket is a decentralised platform that allows users to bet on real-world event outcomes.

TechCrunch reported the charges but did not identify the engineer by name in the wire summary. The complaint was filed in the United States.
