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.

The design is organized around color-coded Crystal Scatters, each tied to a distinct feature path. Every color is paired with a matching skull display and feature path: green for Upgrade, blue for Expand and red for Multiplier, and each feature awards seven spins as standard.

Each path alters a different part of the math model. Upgrade Free Spins turns Bison symbols into Thunder Bison that pay twice the standard value, while Expand Free Spins opens the grid to five reels by six rows and 7,776 payways. The third path introduces multiplier wilds to the middle reels.

The strategic detail is what happens when features overlap. When two feature types activate together, Super Charged Free Spins combines both sets of mechanics, and when all three activate, Mega Stampede Free Spins brings the six-row grid, Thunder Bison and Multiplier Wilds into the same seven spins.

The proposed “integrity and quality” framework aims to establish minimum conditions that operators must meet to maintain or obtain a licence, signalling a strengthening of oversight in the sector. The details of the scoring criteria and an official implementation date remain unpublished.

The timing of regulatory tightening coincides with a vigorous government campaign against scams and illicit financial activities linked to casinos. 

According to Khmer Times, the Cambodian government has announced a landmark decision to suspend all online gambling activities at its casinos starting October 2026.
