About Aztec Spins
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 American Gaming Association estimates that the exchanges have siphoned more than $1.3 billion in would-be tax revenue from states. One of the AGA’s primary spokespeople pin its fight against prediction markets is former New Jersey governor Chris Christie, who championed the PASPA case to the Supreme Court.

Despite a rapid ascension throughout the US, Kalshi has been relatively mum on potential international expansion down the road. There is some sentiment that Kalshi will wait to build abroad until after the completion of an initial public offering. At present, Kalshi has sought a valuation of around $44 billion.
Kalshi has imposed strict protocols for customer sign-up, which includes proof of US residency, along with a US tax identification number. The operator also requires traders to complete a robust know-your-customer check before trading on its site.
Per a nine-page member agreement issued by Kalshi in June, users are required to acknowledge that they are prohibited from trading on event contracts if domiciled in roughly three dozen countries. Australia, by way of the ASIC ban, received inclusion on the list. Under the agreement, Kalshi reserves the right to deny users access to its platform in the restricted jurisdictions.

While such orders have become customary around the nation this year, Connecticut’s missive took it one step further. The department also issued nearly 30 subpoenas to licensed gaming service providers and a bevy of media outlets. Those issued subpoenas include ones served to PayPal, Sportradar Solutions and Plaid, a payment processing app that holds a gaming licence. Although those companies are not under investigation, the subpoenas appear to be the first against service providers that conduct business with prediction markets in some form.
– In the wake of a consequential ruling by the US Court of Appeals for the Ninth Circuit against Kalshi, two operators are taking separate paths in an effort to overturn the decision. On 28 August, the Ninth Circuit ruled in a 3-0 decision that sports event contracts do not qualify as federally regulated swaps under the Commodity Exchange Act. Earlier this week, Kalshi filed for an en banc re-hearing with the Ninth Circuit, this time before an 11-judge review. Robinhood, meanwhile, filed a petition of certiorari with the Supreme Court in a move to effectively bypass the Ninth Circuit. It is widely believed that a circuit split between the Ninth Circuit and a separate decision by the Third Circuit will prompt the Supreme Court to take up the case.
– Real App, a social sports app built around live play-by-play, named FanDuel as its first prediction market partner. The partnership brings FanDuel’s odds and contextual markets directly into the app’s live sports experience. Fanatics Sports & Casino is adding some upgrades to its Fair Play offering. Among the changes, Fanatics has added first-half injury protection for player props. The option proved to be valuable for fans in Wednesday’s opener when Seattle Seahawks quarterback Sam Darnold left the game after the team’s fifth offensive play.
