prediction markets are growing beyond sports.

non-sports volume across kalshi and polymarket jumped 144% in august, with kalshi driving most of the increase.

but the bigger story is what people are actually trading.

markets around real-world events and outcomes are getting more attention, covering everything from elections and economic data to crypto, weather and major world events.

kalshi has now recorded nine straight monthly volume records, reaching $17.91b in may.

its crypto markets also hit a record $217.98m in daily volume on july 15.

combined, kalshi and polymarket are now doing around $9.6b in weekly volume, with kalshi taking about 81% of the market.

prediction markets are becoming more than a place to bet on sports.

they’re turning real-world expectations into markets that people can actually trade.

and this is only getting started.
