Prediction platform Polymarket has begun live testing of its US exchange.

Prediction platform Polymarket has quietly opened its US market to a select group of users and begun live trading tests in preparation for its planned relaunch in the US. The platform stated that the exchange is fully operational, with some users trading real contracts, and that it is currently working on the final steps required to open the exchange. Founder Shayne Coplan said, "The US exchange is actually live and operational, and users are gradually connecting; it's essentially in the testing phase."
