Google Engineer Charged After $1.2M Polymarket Bet on d4vd

A Google software engineer who used a marketing dashboard available to every Googler bet more than $2.7 million on Polymarket between October and December last year, walked away with roughly $1.2 million in profit, and was charged Tuesday in Manhattan federal court with commodities fraud, wire fraud, and money laundering. Michele Spagnuolo, 36, a staff information security engineer who has spent more than 12 years at Google, allegedly knew before the rest of the platform that the singer d4vd would top the company’s 2025 Year in Search list.

The case is the second federal insider-trading indictment tied to Polymarket in 35 days. Both bets cleared the platform during the same six-month stretch in which combined US prediction-market volume scaled from under $5 billion a month to roughly $24 billion.

The Marketing Tool That Cost a Twelve-Year Veteran His Job

Spagnuolo had access to a Google internal tool, available to all employees, that surfaced confidential, nonpublic Year in Search data, the company confirmed in an emailed statement. The Justice Department says he opened the AlphaRaccoon account on Polymarket in May 2024 and began wagering on the Year in Search 2025 markets in October last year. Across the next two months, he risked the $2.7 million figure across at least 25 contracts tied to Google’s annual list, including the “#1 Searched Person on Google this year” and “Top 5 Most Searched People on Google 2025” markets, per the parallel CFTC complaint.

Court papers describe near-perfect accuracy. The account bought “Yes” shares on the eventual winner of the top-searched-person market at a moment when Polymarket had assigned that outcome a near-zero probability. Google publicly announced its Year in Search list on December 4, with d4vd at the top. AlphaRaccoon then moved its winnings in 16 separate transfers between October and at least December, the complaint says.

US Attorney Jay Clayton’s statement on the Spagnuolo indictment, the SDNY release, framed the conduct in classic securities-fraud language: Spagnuolo “violated the duties he owed to his employer and used Google’s confidential business information to make more than $1.2 million in trading profits on Polymarket.” Google called the conduct “a serious breach of our policies” and placed Spagnuolo on leave. He was presented before US Magistrate Judge Sarah Netburn on Tuesday and released on a $2.25 million bond. If convicted on all counts, he faces up to 50 years in prison.

Polymarket’s First US Year Has Already Produced Two Federal Cases

Polymarket only re-opened to US traders in January, after the Commodity Futures Trading Commission (CFTC, the federal regulator for derivatives and event contracts) granted the platform an Amended Order of Designation in November 2025. The venue spent nearly three years offshore. Five months back in the United States have produced two federal insider-trading prosecutions tied to its order book.

The first arrived April 23, when the Justice Department charged then-active US Army Special Forces Master Sergeant Gannon Ken Van Dyke with using classified intelligence on Operation Absolute Resolve, the military mission to capture Venezuelan President Nicolás Maduro, to place 13 bets on Maduro- and Venezuela-related contracts between December 27 and January 2. Van Dyke risked $33,934 and sold his positions for roughly $409,881 hours after President Trump publicly announced the operation on January 3.

Spagnuolo’s case landed 35 days later, on May 27. Two indictments inside six weeks, both tied to material non-public information held by employees of the entity setting the underlying event.

The market backdrop explains why the cases now matter to federal prosecutors. Combined monthly trading volume across Polymarket and Kalshi, the two largest US-facing prediction markets, climbed from under $5 billion in September 2025 to about $24 billion in April, according to Pew Research analysis of Kalshi and Polymarket volume data. Polymarket’s US book alone cleared $1.3 billion in April; its international book ran at $9 billion. CFTC Chairman Michael S. Selig used the Spagnuolo announcement to put down the agency’s marker on event-contract enforcement: “The Commission will not tolerate fraud, manipulation, or insider trading, regardless of the technology or platform used.”

How the d4vd Bet Cleared Near-Zero Odds

The mechanics of an event contract sit closer to a binary bet than a stock trade. A user buys “Yes” or “No” shares in an outcome at a price between zero and one dollar. If the outcome happens, every “Yes” share pays out a full dollar. A share priced at three cents that resolves Yes returns a 33x multiple before fees.

That spread is what Spagnuolo allegedly worked. Polymarket’s order book had the eventual winner at near-zero implied odds for most of the autumn, multiple traders posting on the platform’s public charts in mid-December observed. AlphaRaccoon’s pattern across the Year in Search markets, as the CFTC civil complaint on Year in Search event contracts lays out:

1. Open exposure across multiple contracts. The account traded at least 25 separate Year in Search 2025 markets, not only the top-searched-person book but also Top 5 contracts and 23 additional category markets.
2. Concentrate capital on the d4vd outcome. AlphaRaccoon bought “Yes” shares as the singer’s contract traded at single-digit cents, where Polymarket’s other traders had priced the outcome as improbable.
3. Sit on the position until resolution. Google’s December 4 announcement closed every Year in Search contract at the same moment, paying out the winning “Yes” shares at face value.
4. Sweep the winnings off-platform. AlphaRaccoon executed 16 transfers from its Polymarket account between October and at least December, the complaint says, moving funds out as positions resolved.

A Polymarket spokesperson said the platform was “the only prediction platform to date whose cooperation has led to insider trading charges in the United States” and pointed to blockchain settlement as the structural reason: “Blockchain trading is transparent, traceable, and bad actors leave footprints.” The chronology described in the affidavit reads like a securities-fraud filing, only the underlying asset is a marketing list.

Three Statutes, Untested Together Until Now

Federal prosecutors built the Spagnuolo case on three statutes that have never before been pressed against bets on a corporate marketing dataset: commodities fraud under the Commodity Exchange Act, wire fraud under Section 1343 of Title 18, and money laundering under Section 1956. The same theory of liability the SEC has used on stock-tipping cases for half a century, the misappropriation theory, is doing the work here.

The Misappropriation Theory Travels

Under misappropriation, an employee who trades on confidential information owed to an employer commits fraud against the employer, even if the employer is not in the securities business. The Supreme Court endorsed that framework in United States v. O’Hagan in 1997. The Spagnuolo complaint maps the same logic onto event contracts: the Year in Search data is not securities information, but Google still has a confidentiality interest in it, and an employee who monetizes it on a CFTC-regulated venue has defrauded the employer.

A Congressional Research Note Spelled This Out in Advance

A Congressional Research Service legal sidebar on prediction markets and insider trading law, published before Spagnuolo’s arrest, flagged exactly this fact pattern. Insider trading on prediction markets, the analysis argued, is reachable under the Commodity Exchange Act’s anti-fraud provisions even when the information would not qualify as material non-public information under federal securities law. Prosecutors have now tested the theory in court for the first time:

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.

That statement, from a Polymarket spokesperson Tuesday, captures the platform’s regulatory posture. Polymarket cooperated. Kalshi, the other CFTC-designated venue, has not yet been named in a parallel case, though its volumes track Polymarket’s closely.

The Edge Case Sitting Underneath

The harder question is what counts as protectable confidential information at a company that publishes the same dataset 30 days later. Google’s Year in Search list is non-public until December 4, then a marketing release. A defense argument is already visible in that gap: the data is not a trade secret, not protected by securities law, and freely disclosed weeks after Spagnuolo’s last trade. Federal prosecutors counter that the duty owed runs to Google as an employer, not to any market in the data itself. The first published opinion in the case will set precedent for every similar dataset that trades.

Who Has Insider Access in a Prediction-Market Economy

Sports, politics, and crypto account for about 90% of Polymarket’s global volume since July 2024, per the Pew analysis. Most public commentary has treated the platform as a hedging venue for political and macro outcomes. The Spagnuolo bets sit outside that core: a corporate marketing release, priced as an event contract because Polymarket lists thousands of low-volume markets across pop culture, awards, search trends, and brand announcements.

That long tail is what creates the inventory of potential cases. Every list, ranking, or scheduled corporate disclosure that Polymarket prices is a potential information-asymmetry trade for someone inside the issuing entity. The two federal cases now in court hint at the categories already exposed:

• Government employees with operational intelligence. Van Dyke, Special Forces, military operations. The Defense Department’s insider-threat units already screen for unusual financial activity, but classified-information leaks to event contracts are new territory.
• Tech-platform staff with pre-release product or content data. Spagnuolo, Google, marketing dashboards. Streaming-service launch dates, executive departures, product cancellations, and award-show categories all trade on Polymarket and Kalshi.
• Sports-league insiders and team employees. Referees, equipment staff, medical personnel. Polymarket lists thousands of game-by-game contracts; the integrity exposure runs through every employee who knows a starting lineup before tip-off.
• Award-show and entertainment-industry staff. Oscars, Emmys, Grammys vote-count personnel. Final tallies are confidential until broadcast, and contracts on award outcomes routinely trade six- and seven-figure books.

Polymarket’s spokesperson Tuesday pointed to blockchain settlement as the platform’s structural defense: trades are traceable, accounts can be linked, and cooperation with US authorities is now part of the operating model. That works once a regulator opens a file. Prediction-market firms are still building the surveillance-style trade-monitoring stack that securities exchanges have run for four decades.

Where the Spagnuolo Case Lands Next

Criminal exposure is steep on paper: a 50-year statutory maximum across commodities fraud, wire fraud, and money laundering, though federal sentencing guidelines for first-time non-violent defendants in this loss range typically land far below that ceiling. The CFTC’s parallel civil action seeks restitution, disgorgement, civil monetary penalties, trading and registration bans, and a permanent injunction. Spagnuolo lives in Switzerland; extradition was not required because he was presented before the magistrate judge in person Tuesday.

Google’s response, that the access was through a tool open to all employees but used in violation of confidentiality policies, leaves the company’s exposure narrow. The question for Mountain View is whether the case prompts a tightening of access controls on what was previously treated as soft marketing data. Inside other large platforms, similar dashboards probably get a permissions audit before the end of the quarter.

For Polymarket, the harder test is what the next 12 months of US listings look like. The platform holds CFTC designation, cooperation credit on two federal cases, and roughly $1.3 billion in monthly US volume to defend. If a third indictment surfaces before year-end, particularly one tied to a contract the platform itself approved for listing, the surveillance question moves from cooperation to gatekeeping. If no third case lands by then, the regulatory framework Spagnuolo’s prosecution rests on holds, and prediction markets enter 2027 with their first piece of judicially tested insider-trading precedent.
