Dune, a company that provides tools to track prediction market betting activity, removed two Kalshi datasets from public view on May 15—less than 48 hours after Sportico used them to analyze how much retail bettors were losing on parlays. Dune did not publicly acknowledge taking the information offline until the matter was flagged by a Sportico reporter on social media.
Dune said it restored the once-free datasets last week—but only for its highest-paying customers.
The Norwegian firm announced on its website it would limit the datasets to its top-tier paid plan, called Enterprise. Prospective customers must fill out a form to get a pricing quote for the product. Dune data specialist Alessandro Losi told Sportico in a video call that the plan costs about $40,000 annually for most users. There are two separate Kalshi datasets that remain free, but those ones do not reveal user losses.
While Dune is associated with Kalshi—the companies announced a business partnership in November—they have both denied that Kalshi pressured Dune to remove or reduce dataset access in the wake of Sportico’s reporting, which showed that Kalshi’s retail users shed more than $100 million on parlays over the first four months of this year.
