About Emerald Brewer

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.

What is Emerald Brewer?

The government blocked 548,420 illegal betting and gambling websites between 2006 and 2025, including 84,000 in 2025 alone. 

These comments echo a similar sentiment emphasised at the country’s Directorate of Communications panel event on illegal betting and addiction on 10 September. Deputy Minister of Interior Ali Çelik suggested that curbing addiction would lead to a decrease in illegal betting activity. 

Çelik said: “If we can eliminate this sector, we will also minimise the funds flowing into the hands of the next criminal organisation.”

The blurring line between financial investing and gambling has been accelerated by the rise of prediction markets—exchanges offering event contracts that are federally regulated as financial derivatives. U.S. News found that over 40% of active sports bettors now also participate in sports prediction markets.

Financial advisors continue to urge consumers to view sports wagering strictly as entertainment and to only risk funds they can afford to lose.

Research from Stanford University published in April concluded that sports bettors remain “overoptimistic,” generally expecting to break even despite losing an average of 7.5 cents on every dollar wagered.
