Robinhood Dominates Kalshi Distribution
Polymarket
Robinhood is doing for Kalshi what app stores did for mobile games, turning a regulated exchange into a distribution backend. Kalshi built the licenses, compliance stack, and matching engine, but Robinhood brings the retail audience at massive scale inside a familiar brokerage app. That makes Kalshi look less like a standalone consumer destination and more like infrastructure that other consumer brands can plug into, which is exactly why Robinhood is now moving to own more of the stack itself.

Kalshi monetizes by taking fees on trades, not by acting like a sportsbook. Robinhood can place event contracts in front of millions of brokerage users without building the exchange from scratch, while Kalshi gets flow and liquidity that would be expensive to win user by user.

This volume mix also shows how concentrated the category has become around distribution. In prediction markets, the winning app is often the one that already has funded accounts, daily engagement, and low friction onboarding, which is why Robinhood, Coinbase, DraftKings, and FanDuel are all pushing into the product.

For Polymarket, the implication is that competition is no longer just exchange versus exchange. It is now liquidity venue versus distribution channel. Polymarket has global crypto liquidity and lower fees, but Kalshi has the clearest path into mainstream U.S. retail through partners like Robinhood and PrizePicks.
The next phase is a land grab for who controls the customer relationship and who becomes the invisible execution layer underneath. Robinhood building its own regulated venue suggests large consumer platforms want Kalshi first as a partner, then as a temporary bridge, and eventually as a benchmark they may try to displace with in house infrastructure.
