Google engineer charged with insider trading after betting $2.7M on company’s own campaign data via Polymarket

According to the complaint, a Google engineer risked over $2.7 million on wagers related to Google's 2025 Year in Search campaign. The engineer allegedly used confidential internal data to place bets on the prediction market platform Polymarket, profiting from non-public information about the company’s annual search trends release.

The Charges

The U.S. Securities and Exchange Commission filed the complaint against the Google engineer, whose identity has not been publicly disclosed. The charges center on insider trading, with the engineer accused of leveraging privileged access to Google’s proprietary data. The wagers, totaling more than $2.7 million, were placed on Polymarket, a decentralized prediction market that allows users to bet on real-world events.

The Campaign Details

Google’s Year in Search campaign, an annual report highlighting the most popular search queries and trends, is a closely guarded internal project until its public release. The engineer allegedly had advance knowledge of the campaign’s data, including which topics would be featured and their rankings. This information was then used to place bets on Polymarket contracts tied to the campaign’s outcomes, such as which search terms would appear or how they would trend.

The Platform

Polymarket, a blockchain-based prediction market, has gained attention for allowing users to wager on a wide range of events, from political elections to corporate milestones. The platform operates using cryptocurrency and smart contracts, with traders buying shares in outcomes. In this case, the engineer reportedly used the platform to bet on specific search trends that would be highlighted in Google’s 2025 campaign, a form of trading that regulators argue constitutes insider trading when based on non-public company information.

Market Context

As of today, May 27, 2026, the broader cryptocurrency market shows mixed performance. Bitcoin is trading at $74,216, down 1.9% over the past 24 hours. Ethereum is at $2,016.72, a 2.5% decline in the same period. Prediction markets like Polymarket remain under regulatory scrutiny, with this case likely to intensify debates about the legal status of such platforms.
