Polymarket Introduces 4% Yield Incentive as Kalshi Dominates Prediction Market Volumes
Polymarket is courting long-term bettors with a 4% annualized yield on select geopolitical prediction markets, including the 2028 U.S. presidential election and leadership outcomes in Russia, China, and Ukraine. The daily-paid incentive, funded by its treasury, aims to maintain pricing accuracy through hourly randomized account sampling.
Meanwhile, Kalshi has surged ahead with $500 million in weekly trading volume—62% of on-chain prediction market activity—while Polymarket trails at $430 million. The rivalry highlights a divergence in strategies: Polymarket's yield play for sustained engagement versus Kalshi's volume-driven momentum.
