Vegas Casino Cancels Predict 2026 Conference as States Revolt

(P1) The burgeoning multi-billion dollar prediction market industry faced a significant setback after the Aria casino in Las Vegas canceled the Predict 2026 conference just three days after a contract was signed, citing pressure from Nevada’s powerful gaming regulator. The move highlights a deepening jurisdictional clash between federally-regulated platforms and states that view the new form of trading as illegal gambling.

(P2) "We have never claimed that the Nevada Gaming Control Board directly ordered ARIA to terminate our event," an organizer for Predict 2026 told Barron's, adding that the conference would move to New York. "We have no interest in creating unnecessary conflict with either ARIA or the NGCB. We did not contest the termination publicly for that reason."

(P3) Predict Summit, the conference operator, signed its contract with the MGM-operated Aria on April 30, only to have it terminated three days later. The cancellation follows guidance issued in October 2025 by the Nevada Gaming Control Board (NGCB), which warned licensees that any affiliation with prediction markets could jeopardize their state gaming license. The board has also sued Kalshi, a leading platform, for operating in the state.

(P4) At stake is the future of a market that saw platforms like Polymarket handle over $3.7 billion in volume on the 2024 presidential election alone. While the industry operates nationwide under the authority of the Commodity Futures Trading Commission (CFTC), a growing number of states are mounting legal challenges, creating a complex and uncertain regulatory patchwork that threatens to stall mainstream adoption.

What Are Prediction Markets?

Prediction markets allow traders to buy and sell shares in the outcome of real-world events, with prices between $0 and $1 reflecting the crowd's perceived probability. Winning shares settle at $1, while losing shares go to zero. Proponents argue these "event contracts" are powerful information-aggregation tools, a concept backed by decades of research.

The modern industry is dominated by two main players. Kalshi is the leading U.S.-regulated exchange, holding a CFTC Designated Contract Market license and processing over $13 billion in volume in April 2026. It offers a wide range of markets from politics to weather and powers the backend for Robinhood Predictions. Polymarket, which recently re-entered the U.S. market after acquiring a CFTC-licensed exchange, boasts deeper global liquidity, having handled over $8 billion in volume in April 2026 across its platforms.

A Widening Regulatory Divide

The core of the conflict lies in jurisdiction. The CFTC classifies event contracts as financial derivatives, giving platforms federal authority to operate nationwide, superseding state gambling laws. This allows them to accept traders as young as 18, compared to the 21-plus requirement for state-regulated sports betting.

However, states with entrenched gaming interests are pushing back. Nevada has been the most aggressive, with the NGCB suing Kalshi and Rep. Dina Titus introducing federal legislation to give states veto power over sports-related contracts. The Aria's cancellation of Predict 2026 shows how effective this pressure campaign has been, even without a direct order. Other states, including Washington, Massachusetts, and Arizona, have also filed lawsuits or injunctions. An Ohio federal judge ruled in March that Kalshi's products amounted to gambling under state law.

The industry has seen some legal victories, with a federal appeals court siding with Kalshi in New Jersey in May 2026. The CFTC and the Department of Justice have also sued multiple states to block them from enforcing local gambling laws against federally-registered platforms. For now, the legal landscape remains fragmented, with platforms like Polymarket and OG.com available in most states, while Kalshi's availability is more restricted due to ongoing legal battles. The outcome of these fights will determine whether prediction markets can become a mainstream financial asset class in the U.S.
