Google security engineer Rahul Singh got arrested on Wednesday, May 27, 2026, for allegedly running a $1.2 million insider trading scheme. He used private corporate data to manipulate bets on Polymarket crypto.
This incident is a significant move in how federal agencies monitor digital asset fraud. Singh reportedly used confidential information about upcoming Google product announcements to get an unfair edge in decentralized prediction markets.
Google Security: The Anatomy of the Insider Trading Scheme
Singh’s $1.2 million profit came from a sophisticated misuse of internal systems. Investigators say he tapped into restricted databases that held pre-release software features and acquisition schedules, directly affecting specific outcomes on prediction platforms.
By placing bets before official announcements, he managed to dodge the usual market volatility.

Using Polymarket’s decentralized prediction structure, Singh hid his actions behind pseudonymous crypto wallets. This tactic was meant to obscure transaction trails, making it tough for traditional financial monitoring to link the bets back to him.
Even with these precautions, blockchain analysis and internal Google security logs eventually revealed the connection between his data access patterns and the timing of his high-stakes crypto bets.
Regulatory and Corporate Implications
Following an automated audit that flagged unusual access to proprietary development roadmaps, Google’s internal security and compliance teams acted quickly. The company has since fired Singh and is collaborating with the Department of Justice (DOJ) to find out if other employees were involved.
This case sends a strong warning to the tech industry about the risks of internal data leaks.
The SEC and DOJ have shifted their focus on enforcement for crypto-based insider trading to include decentralized platforms like Polymarket. Regulators now contend that these markets are subject to the same legal oversight as traditional stock exchanges.
The message for decentralized betting platforms is clear: anonymity doesn’t offer protection from federal prosecution when proprietary corporate information is manipulated to sway market results.
Google Security, Polymarket might need to adopt stricter identity verification protocols to meet regulatory requirements in the near future.
