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.

Dutch MPs have raised similar concerns before. In December 2025, CDA MP Straatman asked the state secretary whether websites advertising as “Beste casino’s zonder Cruks” should be taken offline immediately.
In a written response published in January 2026, Arno Rutte, the state secretary at the time acknowledged that enforcement against such sites remained limited, particularly for domains not registered under the .nl extension.
