TL;DR

  • Federal prosecutors charged a Google engineer with insider trading after he allegedly used confidential search‑trend data to win over $1.2 million on Polymarket.
  • The employee is accused of secretly accessing non‑public Google “Year in Search” data and placing highly accurate bets under the alias “AlphaRaccoon.”
  • Investigators flagged a near‑impossible prediction that indie artist D4vd would become Google’s most‑searched person in 2025.

Background

Federal prosecutors have charged Michele Spagnuolo, a 36‑year‑old Google software engineer and Italian citizen living in Switzerland, with insider trading. The indictment alleges that he used confidential Google search data to make more than $1.2 million on the prediction‑market platform Polymarket.

The criminal complaint, unsealed in New York, states that Spagnuolo accessed non‑public Google information—specifically search‑trend data and rankings for the upcoming “Year in Search”—and used it to place bets under the alias “AlphaRaccoon.”

Details of the Alleged Insider Trading

  • Betting activity: Spagnuolo allegedly wagered about $2.75 million on various outcomes tied to Google’s internal search‑trend data.
  • Profit: The trades reportedly generated roughly $1.2 million in profit.
  • Key red flag: A highly accurate prediction that indie artist D4vd would be the most‑searched person on Google in 2025—information that prosecutors say could not have been reasonably forecast using public data alone.
  • Other predictions: He is also accused of correctly betting on which celebrities and public figures would (or would not) appear in Google’s annual trending‑search rankings.

The complaint alleges that Spagnuolo exploited internal Google systems to gain an unfair advantage before the data became public.

The U.S. Department of Justice charged Spagnuolo with:

  • Commodities fraud
  • Wire fraud
  • Money laundering

If convicted on all counts, he faces decades in prison. He was arrested in New York and reportedly released on a $2.25 million bond.

Google has placed the employee on leave and is cooperating with law enforcement.

Prediction Markets Context

Prediction markets like Polymarket operate in a legal gray area. Users bet on outcomes of politics, world events, sports, or internet trends rather than trading traditional securities.

  • Supporters view them as valuable predictive tools.
  • Critics argue they function as betting sites with weak safeguards against insider activity.

Polymarket has faced scrutiny before. Earlier in the year, lawmakers called for tighter oversight after several suspiciously timed bets tied to geopolitical events raised concerns about insider trading. Some regulators and legal scholars warn that such contracts create new opportunities for individuals with privileged information to profit before the public becomes aware.
