Robinhood Powered Kalshi Volume
Kurush Dubash, CEO of Dome, on unified API for prediction markets
Robinhood mattered because it turned Kalshi from a niche destination into backend market infrastructure for a mass retail broker. The important point is not just that Robinhood added volume, but that Kalshi could tap Robinhood's customer base without owning the customer relationship itself. Internal research notes Robinhood was contributing more than half of Kalshi volume, which fits the broader pattern of Kalshi using broker and app integrations to scale faster than a standalone consumer app could.

This setup works like exchange plumbing. A Robinhood user taps into prediction markets inside the Robinhood app, while the contracts are offered through Robinhood Derivatives using venues including KalshiEX. Robinhood owns distribution and user experience, Kalshi supplies regulated market access and liquidity.
-
That makes Robinhood unusually valuable to Kalshi versus a normal affiliate or media partner. Robinhood already has funded brokerage accounts, trading habits, and a low friction interface, so even a small product launch can push a large burst of order flow into Kalshi.

It also explains why prediction markets are fragmenting. Brokerages, sportsbooks, and crypto exchanges increasingly want the economics and engagement of event trading inside their own apps. Once Robinhood proves distribution can move this much volume, every large consumer platform has an incentive to launch or acquire its own venue.
The next phase is a shift from partnership led growth to control of the full stack. Kalshi will keep winning if it remains the deepest regulated liquidity pool behind many front ends. Robinhood and others will keep pushing to internalize more of that flow. Prediction markets are heading toward an exchange layer battle underneath a distribution layer battle.
