Polymarket US app launches 5-minute crypto up/down prediction markets

The significance here is less the product than the posture: Polymarket is pushing a fast-cycle retail format into the US while its compliance history with the CFTC is still an open matter. Ultra-short up/down contracts concentrate activity into minutes and invite scrutiny over whether they function more like gambling than event markets. The audience most affected is US retail users and the regulated venues competing for the same flow. Whether the CFTC inquiry shapes the app's US rollout, and how quickly 5-minute markets draw volume, is the open question.
