Cryptocurrency traders have turned five- and 15-minute bitcoin prediction markets on Polymarket into a high-volume venue, Bloomberg reported March 15, with up to $60 million traded per day according to Dune Analytics. The surge has drawn regulatory attention — the CFTC is seeking public comment on event-contract rules — and prompted Polymarket to build a sports-integrity platform with Palantir and TWG AI to detect suspicious activity.
