US charges Google engineer with insider trading on Polymarket

Spagnuolo allegedly used information he had early access to through his work at Google, which is based in the US, to make bets that saw him rack up $1.2m (£894,330) in winnings.

A Google software engineer was accused Wednesday of allegedly using confidential company information to make over $1.2 million on Polymarket, marking the second significant criminal case tied to trades on the prediction market platform.

Spagnuolo has been charged with money laundering, commodities fraud and wire fraud.

Prediction markets like Polymarket, Kalshi, and others allow users to bet on pretty much anything.
