DOJ charges Google engineer in Polymarket insider trading case

The DOJ charges Google engineer Michele Spagnuolo in a case that puts prediction markets at the center of a corporate-information scandal. Federal prosecutors say the Google software engineer, known as “AlphaRaccoon” on Polymarket, used confidential company data to place bets and turned that access into more than $1.2 million in alleged profits.

At the heart of the case is a simple but explosive claim: prosecutors allege nonpublic Google information was used not to trade stocks, but to wager on event-driven markets. As a result, the case has an unusual edge, tying alleged misuse of insider-style information to the fast-growing world of prediction markets.

The U.S. Department of Justice has charged Spagnuolo with commodities fraud, wire fraud, and money laundering. According to the DOJ, the allegations cover a period from October to December 2025, during which he wagered approximately $2.75 million on markets linked to nonpublic Google information.

DOJ charges Google engineer in Polymarket case

Michele Spagnuolo, identified by prosecutors as a Google software engineer, now faces a set of serious federal charges that go beyond a workplace misconduct claim. The case includes commodities fraud, wire fraud, and money laundering, according to the U.S. Department of Justice.

Prosecutors also identify him as “AlphaRaccoon” on Polymarket, connecting the criminal case to one of the best-known names in prediction markets. That detail matters because it places the alleged conduct inside a public betting venue, not a private side arrangement.

Why this matters is bigger than one defendant. The case signals that authorities are willing to treat alleged abuse of confidential corporate data in prediction markets with the same seriousness usually associated with other forms of financial misconduct.

How prosecutors say the scheme worked

According to prosecutors, Spagnuolo used confidential Google data to place prediction market bets. The DOJ says those wagers were tied to nonpublic Google information, which forms the core of the alleged misconduct.

The government alleges he wagered approximately $2.75 million on those markets. That figure suggests this was not casual activity or one-off speculation, but a sustained and heavily financed betting strategy over a relatively short period.

Why the alleged Polymarket insider trading case is drawing attention

This is one reason the case stands out. Prediction markets often market themselves as a new way to express views on future events, but prosecutors’ allegations suggest those markets can also become vehicles for exploiting confidential information if users have access others do not.

That makes this more than a Google story. It is also a test of how law enforcement views market fairness when the asset being traded is an outcome contract rather than a traditional security.

Alleged profits and timeline

The DOJ alleges that Spagnuolo generated more than $1.2 million in profits from October to December 2025. That alleged gain, paired with the roughly $2.75 million in wagers, gives the case a scale that is likely to draw attention far beyond the immediate legal filings.

The timeline is also strikingly compressed. Prosecutors say the profits were made over just three months, suggesting the alleged conduct was concentrated and potentially highly targeted.

For Google, the allegations raise a different kind of pressure point: not just data security, but what can happen when internal information reaches adjacent markets that are not usually the first place people look for corporate misuse. For prediction platforms, the case sharpens a question that has been hovering over the sector for years — whether access to privileged information can distort these markets in ways that look a lot like classic market abuse.

What comes next may matter as much as the charges themselves. If prosecutors continue building cases around confidential-information misuse in event betting, prediction markets could face closer scrutiny over how users trade, what they know, and whether those platforms are becoming the next frontier for fraud enforcement.
