Google engineer accused of Polymarket insider trading seeks dismissal, arguing trades were gambling

Michele Spagnuolo's defense claims federal authorities lack jurisdiction over wagers made from Switzerland on an offshore platform.

The short version

  • Michele Spagnuolo, a Google engineer arrested for alleged insider trading on Polymarket, filed a motion to dismiss charges of commodities fraud, wire fraud, and money laundering.
  • His defense argues his wagers were international gambling rather than financial swaps governed by the Commodities Exchange Act, and that U.S. authorities lack jurisdiction over a non-U.S. citizen operating abroad.
  • The case reflects broader legal battles between U.S. regulators and states over whether prediction market event contracts constitute regulated financial instruments or state-level gambling.
  • The court must now decide whether to dismiss the federal charges or allow the prosecution to proceed.
