A Google engineer who allegedly made over $1,000,000 after predicting 2025’s most-searched person has now been arrested for insider trading
A Google engineer has been arrested for insider trading after allegedly using confidential company information to place bets on Polymarket, a cryptocurrency-based prediction market platform. Michele Spagnuolo, who worked at Google since 2014, reportedly profited over $1 million from trades placed on the platform, including successfully predicting what would become 2025’s most-searched person.
The case highlights growing regulatory concerns about prediction markets and cryptocurrency platforms, which occupy a gray area in financial regulation. Spagnuolo’s alleged use of non-public information from his position at Google to gain an unfair advantage in betting represents a clear violation of insider trading laws—principles that may increasingly apply to cryptocurrency-based platforms that operate outside traditional financial infrastructure.
The arrest underscores the importance of information security and employee conduct policies at major technology companies. As prediction markets gain mainstream adoption through platforms like Polymarket, regulators face mounting challenges in enforcing existing securities laws across decentralized and cryptocurrency-based financial instruments. The case also raises questions about how traditional legal frameworks adapt to emerging financial technologies.
