What happens in Vegas, stays in Vegas -- or so the slogan goes. But it seems prediction markets can't stay at all.

An upcoming prediction market conference, Predict 2026, to be held at the Aria on the Las Vegas Strip was called off by the casino due to concerns that its gambling license could be jeopardized for hosting the conference, according to a legal notice reviewed by Barron's.

"The [Aria] is issuing this notice in light of Nevada's current regulatory and enforcement position regarding prediction markets," a lawyer for the Aria wrote in a letter terminating the contract between the hotel and conference organizers.

The Nevada Gaming Control Board, which regulates the local gambling industry and controls state gambling licenses, has taken a strong stance against prediction markets. In guidance issued in October 2025, the regulator warned licensees that should they affiliate with a prediction market platform or launch their own, "the Board will consider these developments as it evaluates the suitability of the entity to maintain a Nevada gaming license."

While Predict 2026 isn't sponsored by a prediction market platform, the notice from the Aria's lawyer shows how licensed casinos are seeking to avoid scrutiny from state regulators. "Recently, the Board has even expressed concern about advertising of prediction markets at non-gaming venues owned by affiliates of the hotel," the notice said.

Aria Resort and Casino was built by MGM Resorts and opened on the strip in 2009. It was sold to Blackstone, the private equity firm, in 2021, but is still operated by MGM. The Aria didn't immediately respond to a Barron's request for comment.

Like other legacy gaming companies, including Caesars Entertainment, MGM hasn't made a foray into the nascent and booming world of prediction markets, while relatively newer entrants to the gaming industry, such as DraftKings, have launched their own prediction market platforms to compete with the likes of Kalshi.

Event contracts sold on prediction markets can be tied to the outcome of a sporting event, closely resembling sports betting. Prediction markets like Kalshi say that event contracts are financial instruments subject to the jurisdiction of the Commodity Futures Trading Commission. That federally-regulated status makes them available nationwide to anyone over the age of 18. Some state regulators say sports event contracts constitute illegal gambling, and the prediction market platforms are dodging state gambling taxes.

Officials in Nevada, where casinos prosper, have emerged as some of the most forceful opponents of prediction markets. The Nevada gaming commission has sued Kalshi for offering sports event contracts in the state; in April the platform was briefly banned from operating there. Rep. Dina Titus, (D., Nev.) -- whose district encompasses the Vegas strip -- has introduced legislation to bar prediction markets from offering sports contracts without permission from states.

Predict Summit, the operator of Predict 2026 signed its contract with the Aria on April 30; it was canceled three days later. The conference has since moved its planned location to New York. A spokesman for Predict Summit said its booking fee was returned.

The Nevada gaming regulator didn't respond to Barron's request for comment. A spokesman told CoinDesk on Wednesday that, "The Nevada Gaming Control Board did not direct, request, or otherwise pressure any licensee or venue to cancel or decline to host any recent or upcoming event or conference, as has been suggested."

"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. "We have no interest in creating unnecessary conflict with either ARIA or the NGCB. We did not contest the termination publicly for that reason, and our focus remains on building a strong event for the prediction market industry in New York this December."
