Q3 volume hit a record $188B — and retail is getting crushed

Record activity in Q3

Prediction-market trading volume climbed to a record $188B in Q3 2026, according to zubiqo.com. That represented an increase of nearly 70% quarter-over-quarter.

Volume was also 21x the level recorded in Q3 2025, putting the latest quarter far above the year-earlier period.

Sports drives the surge

According to zubiqo.com, Kalshi’s sports contracts drove the increase. The supplied summary also gives a 40% figure for sports, but cuts off before identifying precisely what that share measures.

The supplied headline characterizes retail participants as suffering, but the available material contains no loss figures or supporting detail. With the source page unavailable, the scale and nature of any retail losses cannot be established from the summary.

What it means for prediction markets

• Activity is expanding sharply: The $188B quarterly total and both growth comparisons establish a substantial increase in trading volume, not whether participants were profitable.
• Sports is a key driver: Kalshi’s sports contracts are identified as leading the surge, but the incomplete 40% reference limits conclusions about their exact market share.
• Retail outcomes remain unverified: The headline’s claim about retail participants is not supported by performance data in the supplied material.
