During the 2025-26 NBA season, Kalshi made waves by granting an equity stake to two-time league MVP Giannis Antetokounmpo. According to the Wall Street Journal, Sweeney’s representatives approached Novig to express interest as a potential investor. Eventually, the company granted her an undisclosed amount in equity.

During the second half of 2026, prediction markets have endured the wrath of a plethora of state governors, most notably Kathy Hochul of New York.

As the NFL season begins, a state in close proximity to the New England Patriots became the latest to attempt to curb the influence of the trading platforms.

About Mystery Museum

The Coin also does more than open features. Six Coins open Hold & Spin with three Re-Spins, where Coins are the only symbols that can land. In that mode they lock into place, reset the respin counter with each new landing, and pay out their collected values when the respins run out. It’s a familiar Hold & Win framework kept intact rather than reinvented.

Players give up the standard mode to access a higher-variance version with steeper multiplier growth

The optional GO Ultra layer is where the release differentiates itself from a routine Hold & Spin title. GO Ultra is the step up. Activating it removes standard Bonus Spins from the feature pool and introduces Super Duper Bonus Spins, with Coins concentrated on fewer reels and multipliers that grow in larger increments.
