Covering the Business of Prediction Markets

[Polytutor @polytutor]

For traders, the fee split matters more than the total. If parlays earn that much, the exchange has every reason to push combos, where the fee hides inside the price. Before buying a parlay, compare its price with the product of the single-leg prices.

Prediction-market exchanges charged ~$1.40B in trading fees in Q3.

Kalshi alone took $1.01B, or 72% of it. Its parlay fees by themselves out-earned Polymarket US.

Political prediction markets get written off based on their volume.

Politics was 0.4% of all US PM trading in Q3, as per the @byPredicted Q3 report.

But open interest, the money people leave in a market, tells a different story.

Politics went from 17% to 23% of it in one quarter, adding $197M. Only parlays grew more.

These are long-dated markets, and they build slowly. Volume alone doesn't show it.

Prediction markets recorded a 75% QoQ increase in notional volume in Q3 2026.

Proud that @americanspend data is behind some of the great insights in the newly published report on prediction markets from @byPredicted.

It's a fascinating look at an emerging industry using our model of the American economy.

I assume "most comprehensive PM report ever" was just hype, but no, this actually is the best *public* snapshot of what's happening in the space right now.
