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.

Here, advertising for online betting sites is positioned differently. Presented as news, the content talks about the highest odds on the market, features offered by operators, regulatory changes and various cases of bettors, ranging from those who made huge financial gains to those who lost everything.
It is very common among the different profiles identified to refer to regulatory bodies, such as the National Advertising Self-Regulation Council and SIGAP (Brazil’s betting management system). They also speak of responsible gaming in a generic way. In many cases, this is associated with illegal operators and potentially irregular advertising practices.
In this context, the regulations developed to protect players begin to function as a means of legitimisation, with illegal operators even using the term “authorised” in their communication and the “.bet” extension in their domain, which is intended only for licensed operators.

The ASA reviewed whether the ads were directed at under-18s through their placement or content. Its rules prohibit advertising through media where more than 25% of the audience is likely to be under 18.
While the audience data did not conclusively define the website’s age demographics, the regulator noted small percentages of under-18s in HLTV’s social channels but found the website’s content and presentation clearly targeted adults.
Ultimately, the ASA ruled that the ads did not breach CAP Code rules 16.1 or 16.3.13 and took no further action.
