About Los Cuatro Esqueletos
The NFL referenced a comparable incarnation of the platform in a letter this summer to the US Commodity Futures Trading Commission on prediction markets. The league was one of several that submitted public comments to the CFTC in regards to the agency’s proposed rules on event contracts.
The comment period opened shortly after several members of a Senate subcommittee alluded to the rise of prediction markets and the subsequent risk of a spike in harassment cases at a May federal sports betting hearing. The hearing, commenced by a US Senate Committee on Commerce, Science and Transportation subcommittee, was held at the Russell Senate Building during the heart of the NBA and NHL Playoffs.
Cruz, who chairs the Senate Commerce Committee, also co-authored the aforementioned Protect College Sports Act with Washington Senator Maria Cantwell. As cloture motion for floor debate of the act began this week, Cruz has expressed optimism that the bill will be signed into law.
What is Los Cuatro Esqueletos?
A hearing before the Supreme Court would be the culmination of what has been the biggest sports betting-related development since PASPA. Perhaps no other issue has united gaming stakeholders from various companies, tribes, states and regulators.
Beginning with the US presidential elections in November 2024, when prediction markets catapulted into mainstream culture, their rise has been undeniable. Kalshi and Polymarket have seen their valuations balloon to $40 billion and $21 billion, respectively, and the majority of the top US bookmakers have scrambled to expand into the prediction space in various forms, either by building their own exchanges, acquiring existing ones or engaging in market-making.
Commercial sports betting generated just under $17 billion in nationwide revenue in 2025, which is why Davenport asserts that the “stakes of this case are exceptionally high”. Kalshi and Polymarket alone posted more than $45 billion in trading volume, which is similar but not identical to betting revenue, in August. That was a 15% decline from July, although that drop is attributed to the conclusion of the Fifa World Cup tournament that month per Yahoo! Finance.
