Google Engineer Allegedly Turned Internal Search Data Into a $1.2M Polymarket Payday
Federal prosecutors say a software engineer exploited confidential Google search trend data to place winning bets on a prediction market — and now faces commodities fraud, wire fraud, and money laundering charges.

Federal prosecutors in New York have charged a Google software engineer with insider trading after he allegedly used privileged access to the company's internal search data to generate $1.2 million in profits on Polymarket, the cryptocurrency-based prediction platform. The FBI alleges the engineer — identified as Spagnuolo in court filings — exploited non-public information about which public figures were trending at the top of Google's search rankings before those results became publicly known. The case represents a landmark collision between Big Tech's data monopolies and the rapidly expanding world of decentralized prediction markets.
The Bet: Who Tops Google's Most-Searched List
The specific bets at the center of the case centered on Polymarket prediction contracts tied to which public figures would rank as Google's most-searched names of 2025. These are the kinds of year-end lists that feel trivial on the surface but carry real informational value — and Polymarket has built a liquid market around exactly this type of outcome. The engineer, prosecutors allege, didn't need to guess. As a Google software engineer with access to internal search infrastructure, he could allegedly see real-time or near-real-time query volume data that the public would only learn about months later when Google published its annual Year in Search report. That information asymmetry, the government argues, is precisely what turned his Polymarket positions into a calculated extraction rather than a speculative wager.
Commodities Fraud in the Age of Crypto Markets
The charging framework is notable. Prosecutors filed counts of commodities fraud, wire fraud, and money laundering — not securities fraud, which is the typical vehicle for insider trading cases involving traditional financial instruments. That choice reflects the legal reality of prediction markets like Polymarket, which operate using cryptocurrency and exist in a regulatory gray zone that securities law doesn't cleanly reach. The Commodity Futures Trading Commission has increasingly asserted jurisdiction over crypto-denominated derivatives, and this case appears to test that framework in court. Wire fraud and money laundering charges add further leverage, suggesting prosecutors believe the alleged scheme involved deliberate concealment of both the trading strategy and the proceeds. If convicted on all counts, the engineer faces potentially decades in federal prison.
"$1.2 million in alleged profits — extracted not through market skill, but through privileged visibility into Google's own search infrastructure before the public ever saw the data."
A New Frontier for Insider Trading Law
This case is likely to define how regulators and courts treat data-driven information advantages in the prediction market era. Traditional insider trading law was built around stock tips and corporate boardrooms. But Google's internal search data is arguably one of the most powerful real-time economic signals on the planet — a live feed of collective human attention at planetary scale. Engineers, product managers, and data scientists at companies like Google, Meta, and Amazon sit atop information architectures that have no equivalent in the pre-internet financial world. The question prosecutors are now forcing into a courtroom: does privileged access to that kind of proprietary signal, when used to profit on financial markets, constitute a federal crime? The indictment says yes. The defense will almost certainly argue otherwise, and the outcome could reshape how tech companies govern internal data access for employees who touch financial markets.
The Spagnuolo case arrives as prediction markets are maturing from curiosity to a genuine financial instrument class, drawing institutional attention and regulatory scrutiny in equal measure. Polymarket processed billions in volume during the 2024 U.S. election cycle alone, and platforms like Kalshi have won hard-fought CFTC approvals to operate in the open. As real money flows through these systems, the incentive to exploit informational edges — whether from insider access, algorithmic advantages, or proprietary data — will only intensify. Google, for its part, will face pointed questions about internal data governance and the controls it places on employee access to search infrastructure. This case won't be the last of its kind.
Editorial Note
Ars Technica is a reputable technology news outlet with strong editorial standards. FBI statements regarding criminal investigations are typically verifiable through official channels and DOJ filings. The specific nature of the allegation (insider trading using non-public data) aligns with established federal crime categories and is plausible given Google's access to search trends.
