Prediction betting platform Polymarket looks set to re-enter the US market and further shake up the wagering landscape after acquiring a company called QCX.

The deal allows Polymarket to return as a regulated player, just weeks after two federal investigations into whether it had unlawfully offered odds to American customers were dropped.

The crypto-based platform, which has been formally banned in the US, France, Singapore and Taiwan, has taken US$6 billion in trades via its predictions market in the first half of 2025.

Its $112m acquisition of QCX allows it to secure licences to operate in the United States and offer real-money trading on real-world event outcomes.

“Now, with the acquisition of QCEX, we are laying the foundation to bring Polymarket home – re-entering the US as a fully regulated and compliant platform that will allow Americans to trade their opinions.” Shayne Coplan, Polymarket CEO, said.

Polymarket has become a global marketplace for betting on opinions, including elections, around the work. There is $36 million matched on the New York Mayoral election alone.
