“Recent launches, including customizable same-game parlays (SGPs), further support our view that Prediction Markets (PM) are increasingly converging with traditional sportsbooks,” observes Macquarie analyst Chad Beynon. “As a result, we now estimate total US PM taker volume to reach $190 billion in 2026E (vs $169 billion prior).”
If the research firm’s $190 billion taker volume estimate proves accurate, it’d represent a more than eightfold increase from the $22 billion taker turnover seen last year.
Potentially boding well for the Macquarie forecast are at least two factors. First, there are signs of turnover increases across a variety of yes/no exchanges. Second, volume surged to start September with those spikes arriving even before the NFL season kicked off.

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.
The Yahoo Finance prediction market section was taken out in April. The companies have now confirmed that the larger deal is also off, as reported by Bloomberg.
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.
