Robinhood launches prediction market platform amid industry caution

Robinhood enters prediction markets as casino giants stay on the sidelines

At the Global Gaming Expo in Las Vegas this week, the companies that built American gambling did not announce a new product. They announced a withdrawal.

MGM Resorts and Caesars Entertainment both said publicly that they will not enter the prediction market space. Their reason was specific: offering event contracts, the CEOs argued, could put their state gaming licences at risk. That is a significant admission. It means the two largest casino operators in the country have looked at the same regulatory gap that Kalshi and Polymarket are exploiting and decided the downside is too large to touch.

Robinhood has reached a different conclusion. The brokerage launched a prediction market platform — the only major capital markets name to do so — while the casino industry was busy debating the threat in a conference room at The Venetian.

The divergence matters more than either decision in isolation. MGM and Caesars are not retreating because the market is unattractive. They are retreating because they hold licences that state regulators can revoke, and they have calculated that the legal exposure is not worth the revenue. That is rational. It is also a structural advantage handed to every platform that does not hold a state gaming licence, which is every prediction market operator currently in the fight.

Bill Miller, the AGA's chief executive, said at G2E that Kalshi alone has processed over $190 billion in sports bets without paying taxes in the states where that volume was generated. His framing was adversarial — he called them "well-funded bad guys" — but the number underneath the rhetoric is the actual problem for the casino industry. That volume did not exist five years ago. It exists now, and it was captured by platforms that treated state jurisdiction as optional pending federal court resolution.

The CFTC claims exclusive jurisdiction over event contracts as derivatives. State regulators say sports-event contracts are gambling under their laws. Courts have not resolved this. In the meantime, the platforms that moved first are processing billions. The ones waiting for legal clarity are watching from a conference floor.

I have seen this pattern before, in a different context. When a regulatory boundary is genuinely contested, the actors who treat the boundary as settled tend to cede ground to the actors who treat it as a question. MGM and Caesars are treating it as settled. Robinhood is treating it as a question.

The casino executives are probably right that the licence risk is real. Nevada regulators have already warned Kalshi directly. The threat is not hypothetical. But Kalshi does not hold a Nevada gaming licence, so the warning lands differently. For a company like MGM, the same conduct that Kalshi is currently doing in federal court would be an existential licence event. For Kalshi, it is litigation.

That asymmetry is not going away when the CFTC finalises its rules. The two rulemakings now at the White House for review will draw a clearer line between event contracts and casino gambling — but a clearer line is not the same as a closed door. Robinhood entering the space while those rules are still being written suggests the platform has made a bet on where the line lands.
