Kalshi's Exchange-Scale Moat
Kalshi
Kalshi’s moat comes from turning a heavily regulated trading venue into a volume machine, where the hard part is building the exchange and the cheap part is handling one more trade. It spent years securing CFTC approval, runs both an exchange and clearing stack, pays market makers to keep books tight, and monetizes retail flow at roughly a 1% take rate. That is the same basic economic shape as mature exchanges, high fixed costs up front, very low marginal cost once liquidity is in place.

Scale compounds through liquidity. More traders and market makers tighten spreads, which attracts more order flow, which gives Kalshi more fee revenue without needing a matching increase in compliance or core infrastructure spend. Kalshi formalized both market maker programs and fee rebates with CFTC filings, showing it is actively subsidizing depth to grow the flywheel.

The closest comparison is not FanDuel, it is CME or Nasdaq. Sportsbooks make money by taking the other side with a house edge, while Kalshi runs a neutral order book and clearing venue. That means economics improve with throughput and reuse of the same surveillance, matching, and clearing systems across more contracts.

This structure also explains why distribution partners matter so much. Robinhood launched its prediction markets hub on Kalshi’s regulated exchange, and interview evidence suggests third party surfaces can send meaningful volume back into the venue. If Kalshi becomes the underlying pipe for brokers, apps, and market makers, it can scale like exchange infrastructure rather than like a consumer app alone.
The next phase is a race to turn prediction markets into a standard asset class with exchange style plumbing underneath. If Kalshi keeps winning sports and partner distribution while preserving tight spreads and regulatory credibility, its fixed cost base should be spread across far more volume, making the business look more like exchange infrastructure and less like a niche betting product.
