What is Magic Crystals?

“The new hub will display probability data from Polymarket for key economic, government, & market outcomes,” said Polymarket in a post on X last November. “Each probability view will be paired with related news, quotes, & analysis from Yahoo Finance + its partners. By combining trusted data with in-depth analysis, the hub will empower investors to make smarter, more strategic prediction market investments.”

Yahoo—which is 90% owned by private equity giant Apollo Global Management, the firm that acquired operating control of The Venetian in Las Vegas—did not elaborate on why the Polymarket integration ended.

Yahoo Finance is one of the most visited financial news websites in the world, implying it’s a blow to Polymarket that its prediction market hub was pulled, but the operator has other prominent financial media deals.

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.

Kelley also cited improvements at Robinhood as a possible factor for the regression at Kalshi. Just before the NFL season, Robinhood took a minority stake in Crypto.com and struck a deal to begin routing NFL contracts to OG.com, the site’s regulated prediction market platform.

A 40% weekly increase at Crypto.com combined with the attrition at Kalshi may reflect the enormity of the Robinhood deal, according to Kelley.

With all activity, beyond just football, Crypto.com recorded trading volume of $350 million for the week, figures from The PM Pulse show. The newsletter, which is in partnership with Aldrin Research for monitoring industry trends, indicated that Crypto saw weekly growth of 41%. While Kalshi and Polymarket accounted for more than $15 billion in weekly volume, four others recorded activity of at least $300 million. Buoyed by a popular Sydney Sweeney ad, Novig increased volume by nearly 34% on the week.
