Kalshi annual trading volume surpasses $148 billion
Kalshi's annual trading volume has surpassed $148 billion this year, according to a post on X by KalshiData. The regulated prediction market's cumulative historical trading volume has exceeded $173 billion. The figures were reported by Odaily and shared on August 9. They come roughly one week after Kalshi, Polymarket, and Polymarket US combined to post a record $50.6 billion in July volume alone. KalshiData did not break out the platform's monthly contribution.
The $148 billion figure makes Kalshi a harder target for prohibition. Congress is weighing a bipartisan Senate bill to ban sports event contracts on CFTC-registered platforms, and record volume gives lawmakers a concrete market to cite. Kalshi is already fighting state enforcement in New York, Wisconsin, Utah, and Washington after judges rejected its federal preemption defense.
High trading totals raise the economic stakes of any ban and complicate the argument that these markets are niche experiments. The platform must now decide whether to deploy its growth story in lobbying or keep metrics private. Either choice shapes how regulators and rivals size its threat. A platform that proves it can self-police insider trading may deflect federal action; one that only publishes volume risks becoming the symbol lawmakers need.
