TLDR: NEW YORKāA Google engineer, Michele Spagnuolo, was charged after allegedly using internal marketing data to place Polymarket bets, winning about $1.2 million. Prosecutors say his search access helped him predict top Google searches before they were public, drawing DOJ and FBI scrutiny.
Key Takeaways:
- Google worker Michele Spagnuolo, living in Switzerland, was arrested in New York after prosecutors tied his bets to Google access.
- Court papers allege he used a tool for all employees to grab confidential marketing information and place winning Polymarket wagers totaling $1.2m.
- If convicted, the case tests how ātransparentā prediction markets handle insider advantage and how access logs can connect accounts.
- FBI linked his Polymarket identities to one opened with an Italian ID, despite bets run through multiple cryptocurrency accounts.
Even in a world that claims to be traceable, the real unfairness is still the shortcut. Prosecutors say a search giantās private staging gave one bettor a head start and a lot of cash.

Q&A
What kind of audit trail can connect a single person to multiple Polymarket accounts?
The case cites account linkage through identity documents and investigative matching across betting and cryptocurrency wallets, turning āseparateā accounts into a single footprint.
Why does access to marketing or internal search rollouts matter more than general market knowledge?
Early rollout intel can move odds before the public sees the data, turning predictions into a timing advantage tied to privileged information.
How might Google change controls after a charge like this?
Expect tighter segmentation of sensitive materials, stronger monitoring of unusual access patterns, and clearer restrictions around employees trading on public facing outcomes.
Does the transparency of blockchain trading prevent insider trading?
Blockchain can show trades clearly, but it does not stop the insider from exploiting information first. It only helps investigators prove who benefited and when.
What happens if the defendant argues the bets were not tied to legally protected material?
Courts will likely focus on whether the allegedly accessed materials were confidential, whether the access was unauthorized, and whether the information was used to steer wagers ahead of disclosure.
