DraftKings co-founder Matt Kalish spent part of Sunday (May 17) attacking prediction-market operator Kalshi, arguing that sports exchanges still fall far short of the experience most bettors expect from traditional sportsbooks.

In a lengthy series of social media posts, Kalish pushed back against growing excitement around exchange-style betting products. He said the technology and usability behind prediction markets remain years behind regulated sportsbook apps that already dominate the US market.

“There’s not a single exchange product experience for normal people that is remotely close to the delivering the caliber of experience that regulated sportsbooks do,” Kalish wrote. “They are 2-3 years of development away.”

Kalish said the current audience for sports prediction markets is made up mostly of highly experienced traders, professional bettors, and financial-market participants rather than ordinary fans placing recreational wagers.

“It’s currently an extremely niche product where only the 1% know what the hell is going on,” Kalish posted, adding that the conversation is dominated by “professional gamblers,” “professional market makers,” and employees or investors tied to exchanges and derivatives products.

He directed much of his criticism toward Kalshi, which has expanded aggressively into sports-focused prediction products while increasing its public marketing push.

“Yet there is one company that is intent to scream from the mountaintops like they have some hot s*** in sports today and that is Kalshi,” he wrote. “Driven by ego and pressure from raising billions, now push crazy comms while booking 1/500th the risk of DK/FD.”

Kalish also argued that inexperienced users entering prediction markets are often at a disadvantage against sophisticated trading firms.

“Normal ppl on Kalshi have no clue the ‘micro mechanics of prediction markets’ … getting orders snap dumped to pro market makers from Wall Street at 40% the value then condescended by the exchange for being noob.”

The comments arrive during a wider industry debate over whether prediction markets could eventually compete with sportsbooks. We reported that DraftKings’ own interest in launching market-making operations tied to prediction markets, even as state regulators intensify scrutiny. Nevada regulators recently moved against prediction-market activity involving major gambling operators, while Bank of America analysts downgraded both DraftKings and Flutter amid concerns that prediction markets could disrupt traditional betting businesses.

Kalish insisted most everyday sports bettors still find exchange products difficult to understand.

“I haven’t heard the 99% of normal mass market sports gamblers who play for fun say they think exchanges are fun or say much other than express confusion,” he posted. “Because the product isn’t there yet.”

He added that heavy promotion is masking weak mainstream demand.

“When Kalshi stops feeding them all what will be left without a real product is the 1% of professional gamblers, professional Wall Street market makers, and those trying to pump their bags.”

Despite the criticism, Kalish acknowledged the argument may sound self-interested coming from a sportsbook executive.

“Please god everyone put your megaphones the f*** away and build a real mainstream appeal product,” he wrote.
