Dune Analytics: Polymarket's global trading volumes have fallen behind Kalshi in recent months; sources: product delays are contributing to Polymarket's decline
Context & Ripple Effects
The two platforms had already moved from a shared volume surge in late 2025 to a clearer competitive split: Kalshi reported higher November volume and added distribution through the Phantom wallet integration.
This report attributes Polymarket’s weaker recent position to product delays, making execution speed—not just category demand—the immediate differentiator between the two rivals.
First-order effects
- Kalshi takes the recent trading-volume lead, strengthening its position with traders and market participants choosing where to place event contracts.
- Polymarket faces a near-term usage setback while product delays constrain its ability to match its rival’s pace.
Second-order effects
- A volume lead can reinforce itself: deeper activity may make Kalshi more attractive to additional traders, while Polymarket is pressured to prioritize delayed product releases.
- Distribution and product features become more consequential competitive levers, as shown by Kalshi’s Phantom integration and Polymarket’s pursuit of approval for US margin trading.
Third-order effects
- If volume leadership continues to turn on product delivery and access, prediction markets may consolidate around platforms that combine liquidity, distribution partnerships, and faster contract innovation.
- The category’s growth will increasingly test whether platforms can expand features while maintaining credible market integrity, particularly as new contract types and suspicious-wager concerns draw attention.
The trend: Prediction markets are shifting from a demand-led boom into an execution-and-distribution contest for durable liquidity leadership.
