About Master Joker

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.

In a statement released in August, ASIC Commissioner Alan Kirkland wrote that users who opt to engage with overseas operators may miss out on “protections” afforded to them on Australian soil. Another regulator, the Australian Communications and Media Authority, banned Polymarket from operating nationwide in 2025. According to the agency, Polymarket violated the Interactive Gaming Act of 2001 by accepting in-play betting on sports events.

Former US congressman George Santos has been permanently prohibited from trading on the prediction market Kalshi, the company announced late last week. 

Friday’s announcement followed an investigation that found he manipulated contract prices linked to his anticipated attendance at the 2026 State of the Union address.

He was also fined $71,356.

About Master Joker

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.
