October prediction-market turnover reaches $118.2 billion as sports dominate spending

Prediction markets recorded $118.2 billion in trading in October 2026, a 59 percent increase from September, according to DeFi Rate.

The total uses a like-for-like comparison: it includes venues DeFi Rate covers for both full months. That makes the reported increase a comparison across the same covered platforms, rather than a measure expanded by adding venues.

Sports account for most paid dollars

Sports represented 68 percent of the dollars actually paid on single markets over the last 30 days, according to DeFi Rate. The summary was published on Nov 1, 2026, at 1:15 AM ET.

That spending share and the October trading total describe different measures and time windows. The supplied summary does not establish that sports accounted for 68 percent of the $118.2 billion monthly total, or identify how much sports contributed to the increase.

What it means for prediction markets

• Activity increased across comparable coverage: The 59 percent rise measures growth across venues covered for both September and October, not necessarily the entire prediction-market industry.
• Sports led the specified spending measure: Its 68 percent share shows a concentration of dollars actually paid on single markets during the last 30 days.
• The growth drivers remain unspecified: The summary provides no venue-level breakdown or category-level contribution to October’s increase.
