About Vegas Starstruck

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.

About Vegas Starstruck

In 2025, Brazil collected almost BRL10 billion ($1.97 billion) in tax revenue from the licensed sector. In the first seven months of this year alone, BRL8.7 billion generated by the activity was delivered to public coffers. The Federal Revenue Service itself estimates that the sector should reach BRL16 billion in revenue during 2026.

Besides revenue collection, another concern is legal and economic. Companies have paid over BRL2.5 billion for licences since the sector’s regulation. Certainly, the end of the activity would lead to litigation to recover the amounts paid and compensation for investments made. Furthermore, the revenue from betting is already included in the Annual Budget Law and the Budget Guidelines Law, which define the priorities for federal government spending.

What worries the sector is not just the threat of drastic measures against legalised betting. So far, the government has consistently fallen short in its attempts to curb the illegal market, which still represents almost half of the segment.

GREF is a cooperative network bringing together national gambling regulators across Europe and beyond to facilitate dialogue, exchange information and share best practice on regulatory strategies. 

Tim Miller, who resigned from the UK Gambling Commission earlier this year, has stepped down from the GREF board and has relinquished his role as treasurer. 

Miller served on the forum for several years and was a key UK figure during a period when the Gambling Commission implemented extensive reforms to online gambling regulation and affordability checks. GREF expressed its gratitude for Miller’s contributions during his tenure.
