PANews reported on May 2nd that, according to The Block , the combined historical trading volume of prediction market platforms Polymarket and Kalshi surpassed $ 150 billion in April , ending a seven-month streak of record-high monthly trading volume since September of last year. Polymarket's active traders dropped to approximately 643,000 in April , down from over 733,000 in March . Both USD trading volume and notional trading volume on its global platform declined, but its US subsidiary, currently under development, and Kalshi as a whole continued to grow. Kalshi rapidly expanded in the US after winning its lawsuit against the CFTC in 2024 , gaining permission to offer election contracts. Polymarket returned to the US through the acquisition of a licensed derivatives exchange and is seeking to relocate its entire global market to the US. Under the new administration, the CFTC has adopted a more lenient and experimental approach to prediction markets, while also suing several states to prevent it from using state-level regulations to block such platforms.
