The company only began sales towards the end of 2025, but Yashin says it has subsequently signed around 30 to 40 contracts. Partners include BGaming, SoftSwiss, 1xBet, 01.tech, and Broadway.
Despite his experience launching businesses, Yashin has been surprised by the enthusiastic reception from the wider industry. Perhaps even more revealing is the feedback from the people tasked with selling the product. According to Yashin, one Swipe Games business development manager with more than 20 years’ industry experience told him he had never found a new product easier to pitch.
The response extends to potential customers. Yashin says that of around 50 leads generated through events and the company’s network, only one decided against integration, leaving Swipe Games prioritising a queue of prospective partners.

“If we just sold the data to Kalshi in order to list the markets but no one was coming in and placing liquidity, there’s no point in them listing the markets,” Monk said. “We also need to supply the data to the market makers to inform their models.”
Catalist initially received a list of fewer than 10 potential market makers from Kalshi. It has since completed agreements with close to 20 and is engaging with approximately another 20.
That growth reflects the expanding number and variety of sports contracts. ITF tennis is particularly dependent on official data because its more than 60,000 annual matches are not generally televised. Unofficially monitoring a tour moving between locations such as Bogotá and Bali would be difficult, Monk noted.

Prediction markets have proven effective at attracting sharp bettors and high-rollers who are often limited or banned by traditional sportsbooks. However, consumer surveys indicate that when given the choice between a sportsbook and a yes/no exchange, most recreational bettors still prefer the traditional sportsbook interface. That dynamic helps explain why prediction markets remain in second place.
“Prediction markets represent a meaningful second channel for NFL wagering but still small on a relative scale, reflecting a new sector with less of an installed base,” observes EKG.
It’s widely believed that all-or-nothing exchanges are carving out significant niches in states, such as California and Texas, where sports betting is prohibited, but there’s also emerging consensus that the prediction market threat to sportsbooks is easing.
