A Zurich‑based Google engineer allegedly accessed confidential Year‑in‑Search data and placed a series of high‑stakes bets on the Polymarket prediction market, netting more than $1.2 million in profits. U.S. authorities have charged him with commodities fraud, wire fraud and money‑laundering, highlighting the commercial value of Google’s pre‑release trend data.
Google Engineer Accused of Insider Trading Using Year‑in‑Search Data

The alleged scheme
Italian national Michele Spagnuolo, a long‑time Google engineer stationed in Zurich, is accused of exploiting his privileged access to the unreleased Year‑in‑Search dataset. Between October 2025 and December 2025 he allegedly logged into internal tools that displayed a red‑banner warning reading “Confidential” and extracted trend forecasts for the upcoming public release.
Armed with that information, Spagnuolo opened an account on the decentralized prediction‑market platform Polymarket under the alias AlphaRaccoon. He placed a cascade of bets on whether specific individuals would appear in the top‑searched list once Google published the official results on 4 December 2025.
Sample bets (as listed in the criminal complaint)
| Bet | Amount (US $) | Implied probability |
|---|---|---|
| Kendrick Lamar most‑searched | 403 | 3 % |
| Pope Leo XIV not most‑searched | 10,807 | – |
| D4vd in top‑5 most‑searched | 381.12 | 18 % |
| D4vd most‑searched | 5 | ≈0 % |
| Bianca Censori not most‑searched | 937,688 | 85 % |
| Donald Trump not most‑searched | 509,149 | 90 % |
| Donald Trump not in top‑5 | 171,612 | 66 % |
The total exposure across all wagers topped $2.75 million. After Google released the official Year‑in‑Search rankings, the AlphaRaccoon wallet showed a profit of roughly $1.2 million.
Blockchain trail and money‑laundering allegations
Forensics on the Polymarket wallet (identified as 5.045 million USDC.e) revealed a rapid outflow of funds to a series of crypto‑exchange addresses. The FBI’s Special Agent Brandon Racz described the pattern as classic “layering” – an attempt to obscure the source of illicit gains.
Key observations:
- The wallet was funded with a single large deposit shortly before the bets were placed.
- Within hours of the Year‑in‑Search release, the balance was split into multiple smaller transfers to exchanges supporting USDC withdrawals.
- Subsequent on‑chain activity showed conversion to Bitcoin and Ethereum, followed by mixing services before finally moving to fiat‑linked accounts.
Why the Year‑in‑Search data matters to traders
Google’s Year‑in‑Search report is a cultural barometer that aggregates global search interest for the preceding year. The surprise factor of the final rankings creates a short‑window where market participants can bet on outcomes that will be publicly confirmed only after the release. In prediction markets, even a few percentage‑point odds can translate into outsized payouts because the market’s liquidity is limited.
From a commercial perspective, the report is a high‑value asset for Google:
- It drives media coverage and reinforces the company’s dominance in search analytics.
- Advertisers use the insights to calibrate campaigns for the upcoming year.
- Competitors monitor the data to gauge shifting consumer interests.
Accessing this data before it is public therefore provides a non‑public informational advantage, analogous to a corporate earnings leak in traditional finance.
Legal ramifications
Spagnuolo faces three federal counts:
- Commodities fraud (under the Commodity Futures Trading Commission’s jurisdiction, as Polymarket contracts are deemed commodity derivatives).
- Wire fraud (using electronic communications to further the scheme).
- Money‑laundering (converting illicit crypto proceeds into legitimate fiat).
If convicted, the statutory maximum across the counts is 50 years imprisonment.
U.S. Attorney Jay Clayton emphasized the precedent: “Corporate insiders cannot use confidential business information to turn a profit in our markets.” FBI Assistant Director James C. Barnacle Jr. added that the agency will continue to pursue “fraudsters who betray their employer for personal financial gains.”
Implications for the tech and crypto communities
- Insider‑access controls – Companies handling pre‑release data must audit who can view it and enforce strict logging. Google’s internal screenshot showing a red “Confidential” banner suggests a visual cue, but the breach shows that visual warnings alone are insufficient.
- Crypto‑exchange vigilance – The rapid conversion of USDC to other assets highlights the need for exchanges to implement robust AML monitoring for large, sudden inflows linked to prediction‑market wallets.
- Regulatory focus on DeFi – This case may prompt the CFTC and the SEC to tighten oversight of decentralized prediction markets, especially those offering contracts that mirror traditional commodity derivatives.
- Corporate policy updates – Firms may now require employees to sign explicit non‑disclosure agreements covering any data that could influence market outcomes, not just financial statements.
What to watch next
- Court proceedings – The next hearing is scheduled for July 2026; the prosecution will likely present blockchain analytics as core evidence.
- Polymarket response – The platform has pledged to cooperate with law‑enforcement and is reviewing its KYC/AML procedures.
- Google’s internal review – Expect a post‑incident report detailing how the breach occurred and what remediation steps will be taken.
