Prediction markets broke their weekly volume record for the fourth consecutive week, with turnover reaching $23.9B last week. The sector's expansion shows no sign of cooling as traders pile into event contracts.
Why it matters
Kalshi remains the main driver of the growth, and its $4B all-time-high daily volume on October 11 underlines how much of the recent expansion is concentrated on a single venue. That concentration is the story within the story: prediction markets are graduating from niche crypto curiosity to a mainstream derivatives category, but the volume base is narrower than the headline numbers suggest.
Market impact
Four straight record weeks is a pace that typically signals structural adoption rather than a one-off event spike, and the sector is now pulling volume that rivals established derivatives verticals. What to watch next is whether growth broadens beyond Kalshi to competing venues, or whether the record streak stays a one-venue story. A single-venue concentration makes the sector's momentum more sensitive to any operational or regulatory disruption at the top platform.
