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.

The two companies began collaborating in November 2025. As part of the deal, Polymarket provided data for a dedicated prediction market section on Yahoo Finance. The feature provided market-based probabilities of economic, political, and financial developments alongside Yahoo Finance content.

Yahoo said Polymarket is still an advertising partner and suggested the two could collaborate on other projects in the future. Polymarket has not provided any public explanation for the end of the data partnership.
