Google Engineer Arrested for Insider Trading on Polymarket

Key Takeaways

• Michele Spagnuolo allegedly used Google's confidential search data to predict outcomes on Polymarket
• The scheme generated $1.2 million in profits from $2.7 million in total wagers
• Spagnuolo faces charges of commodities fraud, wire fraud, and money laundering with a maximum 50-year sentence

A Google security engineer has been arrested in New York for allegedly using confidential company data to win over $1.2 million on Polymarket, a cryptocurrency-based prediction market. Michele Spagnuolo, 36, worked at Google Zürich since 2014 and had access to internal tools showing non-public search trends.

The U.S. Attorney's Office for the Southern District of New York announced charges against Spagnuolo this week. He faces counts of commodities fraud, wire fraud, and money laundering. If convicted on all charges, he could spend up to 50 years in prison.

How the Scheme Worked

According to the FBI complaint, Spagnuolo operated on Polymarket under the handle 'AlphaRaccoon.' Unlike typical bettors, he allegedly knew the outcome of certain wagers before placing them. His access to Google's internal data systems gave him a preview of search trends that the public wouldn't see until later.

FBI agent Brandon Racz wrote in the legal complaint that Spagnuolo "knew the outcome of these wagers before the trading public did because he had accessed Google's confidential, commercially valuable internal data."

One of his successful bets involved predicting who would be Google's most-searched person of 2025. Spagnuolo correctly wagered on D4vd, the musician charged with first-degree murder in April this year. At the time of his bet, public probability for this outcome was essentially zero.

Clear Warnings Ignored

The internal software tool Spagnuolo used displayed a banner stating 'Google Confidential' in red text. According to prosecutors, he had certified his understanding of Google's confidentiality and ethics policies. Using this data for personal financial gain was a clear violation.

“The integrity of prediction markets depends on the public's trust. When insiders exploit confidential information for personal gain, they not only commit a crime but undermine the very purpose of these platforms.”

Google has not issued a public statement, but an anonymous spokesperson told reporters the company has "a zero-tolerance policy for this kind of behavior." Spagnuolo's Google research page has been taken down since his arrest.

The Numbers Behind AlphaRaccoon

Court documents reveal the scale of Spagnuolo's alleged trading activity. The AlphaRaccoon account wagered a total of $2.7 million on Polymarket. His winning bets generated $1.2 million in profit. A judge set his bond at $2.25 million following his arrest in New York.

Polymarket has confirmed that their integrity systems flagged the suspicious trading activity. The platform says it cooperated with the U.S. Attorney's Office and the FBI in the investigation.

Prediction Markets and Insider Risk

This case highlights a structural vulnerability in prediction markets. Unlike traditional securities, these platforms let users bet on real-world outcomes. Sports scores, election results, search trends, game release dates. If someone has non-public information about any of these, they can exploit it.

The irony here is stark. Spagnuolo worked as a security engineer. His job was to protect Google's data and systems. Instead, prosecutors allege he abused his elevated access for personal profit.

Online communities have reacted with a mix of shock and cynicism. On Reddit and Hacker News, many users argue that prediction markets linked to tech-company data are inherently vulnerable to this kind of abuse. Others wonder why Google's internal monitoring didn't catch the activity sooner.

What Happens Next

Spagnuolo has only been charged at this point. Charges do not indicate guilt. He is an Italian citizen and was arrested while in New York. The case will proceed in the Southern District of New York, which handles many high-profile financial crime prosecutions.

The charges carry serious penalties. Commodities fraud and wire fraud each carry maximum sentences of 10 to 20 years. Combined with money laundering charges, Spagnuolo faces up to 50 years if convicted on all counts.
