Michele Spagnuolo allegedly used confidential data to profit on Polymarket bets
Category: Business
In a shocking case of insider trading, federal prosecutors have charged Michele Spagnuolo, a 36-year-old information security engineer at Google, with fraud after he allegedly made $1.2 million by betting on Polymarket using confidential information. The complaint, unsealed on May 27, 2026, in the Southern District of New York, accuses Spagnuolo of utilizing his access to internal Google data to predict that singer d4vd would be the most searched person on Google in 2025.
Spagnuolo was arrested on the morning of May 27, 2026, in New York and has been charged with money laundering, commodities fraud, and wire fraud. Following his arrest, he appeared before a federal magistrate judge, did not enter a plea, and was released on a $2.25 million bond, which included $1 million in cash. According to the complaint, Spagnuolo misappropriated confidential and valuable nonpublic information from Google to place a series of bets on Polymarket, a popular prediction market platform.
Spagnuolo reportedly used a specific internal Google software tool that allowed him access to confidential Year in Search data. This information enabled him to place bets under the account name AlphaRaccoon, which profited significantly after Google publicly announced its Year in Search 2025 results on December 4, 2025. At the time he made his wager, Polymarket assigned a near-zero probability to d4vd being the #1 searched person on Google, making Spagnuolo’s successful bet particularly suspicious.
This case is notable for the substantial amount of money involved and for its implications for corporate ethics and the integrity of prediction markets. Google has publicly stated that it is cooperating with law enforcement in the investigation. A spokesperson for the company emphasized, "Using such confidential information to place bets is a serious breach of our policies. We've placed the employee on leave and will take the appropriate action." This incident raises questions about the safeguards in place to prevent insider trading in digital platforms like Polymarket.
Spagnuolo is also facing a civil case from the Commodity Futures Trading Commission (CFTC), which adds another layer of scrutiny to the situation. This case marks the second high-profile insider trading incident involving Polymarket this year. In April, U.S. Army Special Forces master sergeant Gannon Ken Van Dyke was arrested for allegedly using classified information to make over $400,000 from bets related to U.S. military operations against Venezuelan President Nicolás Maduro. The Southern District of New York’s increasing focus on insider trading in prediction markets suggests that regulatory bodies may be tightening their oversight of these platforms.
In a statement, a Polymarket spokesperson noted, "Polymarket worked closely with the U.S. Attorney's Office for the Southern District of New York and the CFTC, and is the only prediction platform to date whose cooperation has led to insider trading charges in the United States. We are committed to maintaining accurate, fair, and transparent markets as well as enforcing our rules and working with our regulators and law enforcement." This commitment is underlined by the growing concerns about insider trading practices within the prediction market sector.
The Spagnuolo case, alongside the Van Dyke incident, highlights a broader trend of suspiciously timed trades on prediction markets, particularly in relation to geopolitical events and corporate actions. As lawmakers and regulators continue to examine these platforms, the future of prediction markets like Polymarket may hinge on their ability to enforce regulations and maintain market integrity.
With the rise of digital prediction markets and the potential for insider trading, this case serves as a stark reminder of the ethical obligations that come with access to confidential information. As investigations proceed, stakeholders in the tech industry and regulatory bodies will follow closely closely to see how these incidents affect future operations and regulations surrounding prediction markets.
The implications of Spagnuolo’s actions extend beyond just his personal fortune; they raise questions about the ethical responsibilities of employees in tech companies and the necessary steps to safeguard sensitive information. As the legal proceedings move forward, the outcomes could lead to more stringent regulations governing insider trading in the digital age.
As this story develops, the tech community and prediction market enthusiasts alike will be eager to see how these events shape the future of betting platforms and the measures taken to prevent insider trading in the rapidly changing digital economy.
For now, attention turns to the federal court as Spagnuolo prepares for the next steps in his legal battle, with the potential for far-reaching consequences for both him and the prediction market industry.
