Tom Reeg named daily fantasy sports as the last time casinos watched a gray market build a head start they couldn't close.
He said it at G2E on Tuesday, standing on a panel with the chief executives of MGM and Wynn, and the comparison did more work than he probably intended. Daily fantasy sports operated in legal ambiguity for years, then sports betting was legalised and the companies that had run the gray market — DraftKings foremost among them — had the infrastructure, the customer relationships, and the brand recognition that incumbents had declined to build. The casinos are now watching DraftKings move into prediction markets from a position they chose not to occupy.
The reason MGM chose not to occupy it is specific. Bill Hornbuckle said Nevada regulators told the company directly: enter prediction markets in other states and your licensing suitability is at risk. That is not a legal argument or a philosophical position. That is a regulator telling a licensee what the consequence will be. MGM operates nine properties on the Las Vegas Strip. The calculation was not complicated.
Caesars reached a similar conclusion through slightly different reasoning. Tom Reeg has said the company is prepared to enter prediction markets if it can do so without jeopardising its licences. The conditional matters. It means Caesars is not opposed in principle — it is constrained by the same Nevada licensing pressure that stopped MGM, waiting to see whether the regulatory ground shifts before it commits.
This is where the DFS parallel breaks down, and where Reeg's own analogy works against him. When DraftKings built its DFS business in the gray market, the licensing risk was theoretical. There was no regulator with the specific authority and the specific willingness to act on it. Nevada's Gaming Control Board has already demonstrated both. Kalshi was pushed out of the state in August after the Ninth Circuit found that federal commodities law does not insulate prediction market operators from state enforcement. That is not a theoretical risk — it is a precedent that has already cost a platform its Nevada presence.
The AGA's Bill Miller told G2E attendees that Kalshi has processed more than $190 billion in sports contracts while paying nothing in state gaming taxes. The number is meant to land as an outrage, and in the context of casino economics it functions as one. But the casinos most capable of competing chose not to, and their reason was regulatory, not moral.
The prediction market that survives the current litigation will have built its user base, its liquidity, and its brand during the period when its better-capitalised competitors stood aside. Reeg knows this. He said it himself. The DFS parallel is not a warning about what might happen — it is a description of what is already happening, and the casinos are on the wrong side of it for reasons they freely admit are structural rather than strategic.
Nevada's Gaming Control Board explicitly warns casino licensees that entering prediction markets in other states puts their licensing suitability at risk. Bill Hornbuckle said MGM received direct notice from Nevada regulators that operating prediction markets outside the state could jeopardize the company's nine Las Vegas Strip properties. This regulatory threat—not legal prohibition—has prevented major casinos from competing in the emerging prediction market space.
MGM chose not to enter prediction markets after Nevada regulators warned that doing so would threaten its licensing suitability. Caesars reached a similar conclusion and stated it is prepared to enter prediction markets only if regulatory conditions shift to eliminate the licensing risk. Both companies viewed the regulatory constraint from Nevada's Gaming Control Board as structural, not a matter of competitive strategy or market opportunity.
Kalshi was forced out of Nevada in August after the Ninth Circuit found that federal commodities law does not insulate prediction market operators from state enforcement. This precedent demonstrates that Nevada's Gaming Control Board has both the authority and willingness to act against prediction market platforms. The AGA noted Kalshi processed over $190 billion in sports contracts while paying nothing in Nevada gaming taxes, highlighting the regulatory and economic stakes.
DraftKings operated in legal ambiguity during daily fantasy sports' gray market phase, building infrastructure, customer relationships, and brand recognition before sports betting legalization. When sports betting became legal, DraftKings' head start made it difficult for casinos to compete. Tom Reeg warned that prediction markets are repeating this pattern: while casinos remain absent due to Nevada licensing restrictions, prediction market operators are accumulating users, liquidity, and brand during the regulatory window when better-capitalized competitors stand aside.
