PropMarket launches prop trading firm for prediction markets
PropMarket, a New York startup, launched as a proprietary trading firm built for prediction markets, the company announced Thursday, June 5. The firm applies the classic prop-trading model — backing traders with firm capital — to the prediction-market sector, introducing a funding model for traders on Polymarket. PropMarket enters a market experiencing growing institutional and retail interest in event contracts. The New York-based firm is positioning itself as the first proprietary trading firm designed specifically for prediction markets rather than traditional equities, crypto, or forex. The launch offers Polymarket traders access to structured capital allocation reminiscent of institutional prop shops.
Polymarket gains a dedicated capital pipeline for retail traders seeking leverage without personal margin, differentiating its ecosystem from Kalshi and Robinhood's Rothera where such infrastructure remains absent. The move concentrates more trading flow through Polymarket's venue just as Sportradar signs a multi-year data deal for Kalshi sports event contracts.
Joins the accelerating institutional buildout around prediction-market infrastructure alongside Kalshi's Sportradar data deal, Robinhood's Rothera exchange launch, and Crypto.com's FanDuel Predicts partnership, as platforms race to capture both retail and institutional event-contract flow.
