Robinhood Becomes Kalshi Rival

Robinhood owning the exchange and clearing stack means Kalshi is no longer just borrowing an app with a big audience, it is feeding volume to a company that can now keep that flow for itself. In prediction markets, the venue that lists the contract, matches the trade, and clears the position controls the fees, the liquidity, and the customer relationship. Once Robinhood gained its own CFTC licensed market infrastructure through MIAXdx, it moved from reseller to rival.1 2 3 4 5

• The practical difference is where the trade lands. Under the old setup, Robinhood brought users and Kalshi ran the market underneath. With MIAXdx, later renamed Rothera, Robinhood can list contracts on its own venue and clear them itself, so economics that used to flow to Kalshi can stay inside Robinhood and its joint venture.3 4 5
• This matters because Robinhood is not a small affiliate. Internal research on Kalshi shows Robinhood contributes a very large share of volume, and later research describes Robinhood routing some of its highest volume World Cup contracts to its own exchange. That turns partner concentration into infrastructure risk, not just marketing risk.1 2 5
• The broader pattern is that distribution partners across prediction markets increasingly want to own the rails. Research across Kalshi, Polymarket, and the Dome interview shows DraftKings, Coinbase, Kraken, and others either partnering temporarily, buying licenses, or building their own venues. Distribution is becoming a wedge into exchange ownership.1 2 6

The next phase is a fight over who becomes the default liquidity engine. If Robinhood successfully moves its users onto its own regulated venue, Kalshi will need deeper direct demand and more broker partners to avoid dependence on a single distributor. The likely end state is a more fragmented market with several licensed venues competing for the same contracts and traders.1 2 6
