The $1M in 24 Hours That Ended in Federal Charges

In December 2025, a Polymarket account trading the 'd4vd' Google most-searched markets cleared more than $1 million in under 24 hours. It was not a modelling edge: in May 2026 the US Department of Justice charged a Google software engineer with using confidential internal data on Google's most-searched list, alleging roughly $1.2M in insider-trading profits. We include it as a cautionary case, not a strategy to copy.
