TLDR: A Google information security engineer, Michele Spagnuolo, was arrested for Polymarket betting on Google’s 2025 Year in Search results, profiting $1.2 million. Prosecutors say he used nonpublic marketing data about the top searched person to place bets, then tried to hide the proceeds.
Key Takeaways:
- Google’s Year in Search ranks the most searched people, and Polymarket lets users bet on the outcomes.
- Michele Spagnuolo allegedly used confidential Google marketing material to bet on the top searched person, winning about $1.2 million.
- Charges include wire fraud, money laundering, and commodities fraud, raising the risk that insider knowledge becomes the next big enforcement target.
Prediction markets were supposed to be clever, not confidential. This case shows how fast inside access turns “data” into a crime story, even inside the search giant.

Q&A
If Polymarket bans or limits access to certain categories, what would investigators look for next in cases like this?
They would likely focus on trading trails and device level access logs showing how nonpublic information reached specific accounts.
Why does a bet that sounds like fandom gossip become wire fraud and commodities fraud in practice?
Prosecutors treat the profit motive plus concealment and use of nonpublic information as fraudulent conduct tied to regulated commodities and interstate communications.
What changes for Google teams when marketing data can become betting advantage?
Expect tighter controls around who can view drafts and recap assets, plus more monitoring for unusual browsing tied to employee accounts.
How do prediction market odds factor into proving intent?
Very low implied probabilities paired with unusually accurate outcomes can help show that someone had more than ordinary public information.
If insiders fear arrest, will prediction markets shift toward slower, public data only?
Many traders already prefer public signals, but enforcement risk can push others further toward transparent sources and away from anything resembling internal leaks.
