A Google engineer has been arrested and charged in New York over an alleged insider trading scheme that turned confidential Google search data into more than $1.2 million in Polymarket profits.
Michele Spagnuolo, also known as AlphaRaccoon, faces commodities fraud, wire fraud and money laundering charges. The case centers on Google’s 2025 Year in Search results, a high-profile annual release that ranks the year’s top trending searches before those results become public.
Federal charges accuse Spagnuolo of using access to Google’s internal systems to view confidential search-trend data, then placing bets on Polymarket markets tied to which people would appear in Google’s 2025 search rankings. The AlphaRaccoon account risked about $2.75 million between October 15 and December 4, 2025, across roughly 25 Google-related outcomes before the markets resolved.
The most explosive part of the case is the timing. The charges say Spagnuolo accessed confidential 2025 Year in Search data on October 15, then began trading related markets the next day. He allegedly accessed the data again on November 27, when internal results showed that d4vd had moved into the top position. Hours later, the AlphaRaccoon account placed bets tied to d4vd ranking among the top searched people and becoming the No. 1 searched person.
The 2025 Google Year in Search results were made public on December 4. The relevant Polymarket markets then resolved, and the AlphaRaccoon account allegedly generated about $1.2 million in profits.
Insider Risk Hits Event Markets Directly
The case lands at a critical moment for prediction markets. Polymarket has grown into one of crypto’s most visible event-trading platforms, but markets tied to private data, corporate announcements and official releases create an obvious information-risk problem. If one trader knows the outcome before the public does, the market stops functioning as a fair probability venue and becomes a payout machine for insiders.
The charges also describe attempted concealment after the markets resolved. The AlphaRaccoon account allegedly sent millions in USDC.e to a linked wallet, moved funds through crypto swaps, and used a service marketed around privacy protection. The account’s public AlphaRaccoon username was later removed after online communities began speculating about a Google insider.
Spagnuolo has not been convicted. The charges carry maximum penalties of 10 years for the commodities fraud count, 20 years for wire fraud and 20 years for money laundering, with any sentence decided by a judge if the case reaches that stage.
The timing is difficult for the broader prediction-market industry. Polymarket is already fighting questions around mandatory KYC claims and its Perps beta, while Robinhood is moving toward AI agent trading for crypto and prediction markets. The case also lands while Alphabet remains under heavy market attention, with GOOGL price analysis watching the $402 target if $383 support holds. State and federal regulators are also battling over event-contract authority as prediction markets move further into politics, sports, economics and corporate outcomes.
For Polymarket and its rivals, the message is clear: liquidity growth alone will not be enough. Event markets need stronger surveillance, better insider-risk controls and clearer rules for markets linked to confidential corporate data. Without that, every high-profile trading win tied to private information becomes another argument for tighter oversight.
