About Star Spinner

One day before a primetime showdown between the University of Mississippi and Louisiana State University, the Tunica-Biloxi Tribe of Louisiana announced the launch of a tribal prediction market app. The new app, powered by Kalshi, will be launched through SaltTrade Derivatives, a newly established subdivision of a tribal-owned enterprise.

Through the collaboration, the tribe will draw upon Kalshi’s established infrastructure and market expertise to develop a distinct tribal-owned trading application, said Tunica-Biloxi Chairman Marshall Pierite in a statement.

“This partnership represents exactly the type of opportunity Indian Country should be pursuing, where Tribes are owners, innovators and leaders, not just participants,” he said. “For generations, the Tunica-Biloxi people have adapted, traded and built relationships that allowed our Nation to prosper. This initiative carries that tradition into the modern economy.”

What is Star Spinner?

For the right audience, likely professional traders and sophisticated retail investors, the CME futures on FutureSports indexes could amount to “Goldilocks” offerings because the derivatives aren’t standard sports bets nor are they carbon copies of the event contracts traded on prediction markets.

The MLB and NHL futures contracts could be deployed by big-money bettors as hedges on various team exposures over the course of those leagues’ seasons.

As for the regulatory outlooks for the ETFs, the SEC hasn’t publicly commented on the NHL funds’ fates and it’s too early to tell what will come of the MLB filings, but there are hundreds of futures-based ETFs on the market today.

Enda Kendrick, chief executive of service provider Veltium, similarly says the largest UK and European sharp-betting groups have moved rapidly into US prediction markets. He believes there are also more than 100 smaller operations, ranging from individual traders to teams of around 10, interested in entering the regulated US market.

Yet the presence of professional counterparties complicates the customer-facing idea that prediction markets merely allow users to trade opinions with one another. As Kendrick puts it, two ordinary customers are not going to place $10 million or $20 million behind the Philadelphia Eagles. Markets at that scale require institutions.

For Marantelli, the exchange format could also cause some customers to lose money faster than they would with a conventional sportsbook. The ability to enter and exit positions creates a perception of flexibility, but that optionality can encourage users to commit more of their bankroll.
