Kalshi surpassed $10 billion in weekly notional volume for the first time this week, a milestone that arrived during the FIFA World Cup. The headline masks a more durable story buried in the user data.
A 90-day study of 857,000 Polymarket users by Bitget Wallet found that 60% had no prior onchain trading history. Once they arrived, they stayed. Over the study period, these users averaged 1,194 prediction market interactions compared with just 12 DEX trades. Prediction markets aren't funneling new users into broader crypto trading. They're keeping them.
The World Cup illustrated how fast that audience scales around live events. Kalshi processed $2.9 billion in World Cup trades within eleven days, surpassing its entire March Madness volume. Polymarket's football markets hit $5 billion, a leap from $138,000 in World Cup trading in 2022. The volume differential isn't just growth. It signals a pivot from niche crypto activity to event-driven entertainment.
Kalshi has topped $2 billion in annualized revenue. Polymarket crossed $1 billion annualized revenue six weeks after opening its US exchange, according to CNBC. Citizens Bank projects the sector reaches $10 billion in annual revenue by 2030. These are real financial businesses, not side projects.
But the revenue mix reveals a structural constraint. Toni Gemayel, head of prediction markets at Coinbase, noted that only about 1% of users engage with prediction markets the way they would with any other asset class. The rest treat them "almost as an alternative to traditional media or entertainment." A user base betting on elections, policy decisions, and sporting tournaments isn't tethered to crypto market cycles. When digital assets crater, prediction markets keep humming.
almost as an alternative to traditional media or entertainment.
That decoupling is both strength and liability. Event-driven engagement doesn't depend on blockchain sentiment or altcoin seasonality. A major election or tournament generates volume independent of market conditions. The weakness is stickiness without a catalyst. When the World Cup ends, when the election passes, what does a user with no trading background and no interest in broader crypto do next? The platforms have built a business on real-world events. Proving those users return during quiet periods will determine whether this remains a seasonal phenomenon or a durable market segment.
