Federal prosecutors in the United States have charged a Google software engineer with allegedly using confidential corporate information to generate more than $1.2 million in profits through prediction market trading on Polymarket. The case adds a new layer of scrutiny to insider trading risks in event-based crypto markets and raises questions about how companies monitor sensitive information leaks.
The U.S. Attorney’s Office for the Southern District of New York unsealed a complaint on May 27, 2026, against Michele Spagnuolo, a software engineer at Google. Prosecutors allege that he operated under the alias “AlphaRaccoon” while placing trades tied to unreleased internal Google data.
“A Google employee allegedly used confidential information to make more than $1.2 million through insider trading on a prediction market,” said U.S. Attorney Jay Clayton. “Corporate insiders who misuse confidential information to trade for personal gain will be prosecuted.”…

Allegations center on confidential search rankings data
Court filings state that Spagnuolo accessed internal Google systems that contained nonpublic information, including data linked to the company’s “Year in Search 2025” rankings. According to the complaint, he used that information to place at least 25 trades on Polymarket contracts tied to the most searched individuals of the year.
Prosecutors allege that from October to December 2025, Spagnuolo risked approximately $2.7 million across these markets. Once Google publicly released its search rankings, the positions resolved and generated around $1.2 million in profit.
The U.S. Attorney for the Southern District of New York, Jay Clayton, said:
“Today’s charges reinforce a decades-old message: corporate insiders cannot use confidential business information to turn a profit in our markets.”
The statement framed the case as part of a broader enforcement push against misuse of internal corporate data for financial gain.
Account activity and fund movement under investigation
Investigators allege that the “AlphaRaccoon” account became active in May 2024 and later concentrated trading activity on Google-related prediction contracts. The account reportedly placed bets shortly after accessing internal systems, which raised internal and external suspicion over time.
Court documents also reference community discussions on Discord and X that identified unusual trading patterns linked to Google-related outcomes. According to filings, the account name was later changed to a wallet address after those discussions surfaced.
Prosecutors further allege that funds associated with the account moved through decentralized swapping services and a privacy-focused transaction platform. The complaint describes these flows as part of attempts to obscure transaction history.
Parallel civil action expands enforcement pressure
Alongside the criminal complaint, the Commodity Futures Trading Commission filed a separate civil case against Spagnuolo. The agency alleges violations of the Commodity Exchange Act and seeks restitution, disgorgement, monetary penalties, and trading bans.
CFTC Chairman Michael S. Selig said:
“As I have said repeatedly, the Commission will not tolerate fraud, manipulation, or insider trading, regardless of the technology or platform that is used.”
The enforcement division also emphasized its jurisdiction over prediction markets. Director of Enforcement David I. Miller said:
“Employees who are entrusted with confidential business information cannot misappropriate that information for personal financial gain.”
The agency described its role as “a cop on the beat” for misconduct in prediction markets and related financial systems.

Prediction markets face rising regulatory scrutiny
The case arrives amid growing regulatory attention on event-based trading platforms. Lawmakers in the United States have questioned oversight standards in prediction markets, particularly around contracts tied to geopolitical or corporate events.
Earlier legislative inquiries raised concerns about whether insiders could exploit nonpublic information to trade on platforms such as Polymarket. Those discussions focused on whether current enforcement tools adequately address prediction market structures.
The Spagnuolo case now adds a corporate dimension to those concerns. It connects internal data access at a major technology firm with trading outcomes on a decentralized prediction platform.
Broader enforcement context strengthens federal focus
Federal authorities have previously pursued cases involving insider access used for event-based trading. In earlier actions, regulators examined trading tied to political outcomes and classified information. The current case extends that enforcement pattern into corporate search data.
The Department of Justice charged Spagnuolo with commodities fraud, wire fraud, and money laundering. Prosecutors said the combined charges carry a maximum sentence of 50 years in prison.
Officials also highlighted coordination between agencies. The CFTC noted assistance from federal prosecutors in building the parallel civil and criminal actions.
Market integrity questions intensify around prediction platforms
Prediction markets continue to expand as trading venues for event-based contracts, but the structure creates new compliance challenges. Access to nonpublic information, combined with fast settlement mechanisms, can produce sharp profit opportunities when outcomes resolve.
In this case, prosecutors argue that internal Google search data provided a direct informational advantage. That advantage translated into concentrated bets and eventual profits once public disclosures aligned with private knowledge.
The complaint also places attention on how funds moved after trading activity. The use of decentralized services and privacy tools reflects a broader pattern in digital asset flows that regulators continue to track.
Case adds pressure to evolving regulatory framework
The legal action against Spagnuolo intersects with ongoing debates over how prediction markets should be regulated in the United States. Federal and state authorities continue to dispute jurisdiction over event contracts, while platforms face parallel enforcement actions and lawsuits.
The outcome of the case may influence how regulators interpret insider trading rules in prediction markets. It also highlights the compliance challenges faced by firms operating at the intersection of crypto infrastructure, derivatives trading, and information-sensitive corporate environments.
For now, the charges signal continued expansion of enforcement into areas where traditional insider trading rules meet newer digital trading systems.
