How to play Biggest Vault
The decision follows a long-running battle over the multimillion-dollar solar project, which the Upper Sioux Community began developing in 2024 to curb electricity costs and advance its clean-energy goals.
In November 2024, Minnesota Valley issued the tribe a cease-and-desist order and threatened to disconnect Prairie’s Edge if the system was activated. The tribe countered that the utility’s generation restrictions did not apply because the system was designed solely to power its own property and would not feed electricity back onto the grid.
The array, which includes an 800-kilowatt battery storage system, is expected to cover about 30% of the casino’s electricity needs. Prairie’s Edge is the Upper Sioux Community’s principal economic engine, helping fund housing, healthcare, education, and public safety.

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.
A customer might buy a team at 55 or 56 cents expecting the price to rise to 58 or 59 cents, he explains. If it falls to 45 cents instead, the trader may refuse to accept the loss and continue holding the position.
“People will lose money faster on exchanges for lots of reasons,” Marantelli says. “It inherently increases spend, volatility, lots of things. And you’re playing against a sharper audience than you’re playing against at the DraftKings sportsbook.”
