US Department of Justice ends investigation into crypto prediction platform Polymarket.

The claim that the US Department of Justice (DOJ) ended its investigation into Polymarket is accurate. Polymarket, a crypto-based prediction market platform, had been under scrutiny by US regulators and law enforcement for allegedly allowing US users to place bets on its platform, which raised legal concerns about unregistered derivatives trading. The investigation intensified during the Biden administration, including FBI actions such as raids on the CEO's home.

However, according to a Bloomberg report dated July 15, 2025, the DOJ formally closed its probe into Polymarket as the Trump administration sought to support the crypto betting industry. This closure marks a significant regulatory development for Polymarket and similar platforms. The Wikipedia entry also notes Polymarket's prior settlement with the Commodity Futures Trading Commission (CFTC) and its blocking of US customers since 2022, providing context for regulatory challenges faced by the platform.

The sources consistently indicate that while investigations were active and serious, they have now been concluded by the DOJ, confirming the claim's core factual assertion. There is no evidence contradicting this closure or suggesting ongoing DOJ investigations post-July 2025.
