Michele Spagnuolo, a Google security engineer and Italian national living in Switzerland, allegedly pocketed $1.2 million on Polymarket by betting on the most-searched person of the year on Google. The market assigned that outcome near-zero probability. Spagnuolo, according to the indictment filed by the U.S. Attorney’s Office for the Southern District of New York, already knew the result because he had accessed Google’s confidential internal search data. In late May 2026, Manhattan prosecutors arrested him on charges of commodity fraud, wire fraud, and money laundering. The case has reignited a fundamental debate about insider trading on prediction markets.
The Near-Zero Bet That Paid $1.2 Million
Spagnuolo, 36, operated under the account name “AlphaRaccoon.” Prosecutors allege he wagered that singer d4vd would be the most-searched person on Google in 2025, at a moment when the market was pricing that outcome at near-zero probability. Google publicly announced its Year in Search results on December 4, 2025. By that point, the AlphaRaccoon account had already collected $1.2 million. The detail that sealed the case against him is timing: he knew the outcome before the public because he had consulted his employer’s commercially sensitive, confidential data. Several observers had flagged the account as suspicious as early as December 2025.

How a Security Expert Got Caught by a Public Ledger
Functionally, the irony is sharp. Spagnuolo’s job was protecting information. What exposed him was the simplest possible detail: his bets were public, permanently written on a blockchain ledger that anyone can read. The “sure bet” that confidential data made possible was the same transparency that destroyed him. After winning, prosecutors allege he attempted to conceal the origin and ownership of the funds, and that concealment attempt is what triggers the money laundering charge. The line between legal trading and criminal conduct on prediction markets mirrors the wider debate SpazioCrypto has covered on commodity versus security classification.

Polymarket Sides With Prosecutors, Not Victims
Polymarket didn’t play the passive victim. A company spokesperson stated that Polymarket worked closely with the U.S. Attorney’s Office for the Southern District of New York, claiming to be the only prediction market whose cooperation has so far produced an insider trading indictment in the United States. The timing is deliberate. Polymarket is re-entering the American market after years of exile following a CFTC penalty, has received a $2 billion investment from the parent company of the NYSE, and counts Donald Trump Jr. among its advisory board members. Cooperating with federal prosecutors, in that context, is as much a credibility play toward Wall Street and regulators as it is a legal obligation.
What This Changes for Prediction Markets
This is the second case in just over a month. In April 2026, a special forces soldier was charged with using classified information to bet on Polymarket on the fate of Venezuelan President Maduro, collecting more than $400,000, according to DOJ filings. The uncomfortable issue is theoretical, not just judicial. Prediction markets market themselves as truth machines that aggregate dispersed information into accurate probabilities. That promise structurally rewards those who know more than everyone else. And those who know more than everyone else, on regulated markets, frequently commit a crime.
The CFTC maintains that event contracts are regulated swaps. The operational boundary remains undrawn, as we explored in our analysis of the Clarity Act. As Polymarket expands in the United States, every “sure bet” risks becoming a federal case. Spagnuolo has entered a plea before charges that prosecutors intend to use as precedent. The public ledger that makes prediction markets compelling is precisely the evidence that condemns them. The primary source for this case is the U.S. Attorney’s Office for the Southern District of New York; regulatory oversight of event contracts falls under the Commodity Futures Trading Commission.
