Silent Samurai

What is Silent Samurai?

MFS operated as a non-bank lender—often termed a “shadow bank”—that borrowed funds from institutional investors to finance property loans for its clients.

The company experienced rapid expansion prior to its collapse, with its loan book reaching approximately £2.4 billion ($3.2 billion) by the end of 2024. Its creditors included major international financial institutions and private equity firms.

In March, courts in London and Dubai imposed a worldwide freezing order on Raja’s assets up to £1.3 billion.

About Silent Samurai

“They lose quicker, dry up quicker, recruitment or re-recruitment,” he says. “If the recruitment of players dries up, then what are you going to do? Definitely there can be components like that.”

The result is an emerging ecosystem that looks less like millions of customers casually trading predictions with one another and more like an outsourced sportsbook trading room. Exchanges own the platform and recruit the customers; specialist firms price the risk and provide the money needed to make those markets function.

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.
