About Mighty Masks

An Australian casino player is taking Royal Caribbean to court, arguing that the company banned him from sailing with its services and from playing at its casinos over his ability to count cards. After previously winning a legal battle against Star Casino, Mark Timothy Grant is now moving to confront the cruise line. 

Grant argues that he has booked five Royal Caribbean cruises that were valued at a total of AUD 22,000. He booked the cruises with money he won playing at the Royal Caribbean’s ships’ casinos. 

However, before he could even board the first cruise, Grant was told that he would not be able to proceed onboard. Grant had his son and partner along with him. The company only then went to inform Grant that he had been placed on a “no sail” list, effectively a ban, because of “breaking the house rules” in the casino.

The difference is all about the risk function. A sportsbook employs traders to price bets and manage its exposure. An exchange provides an API through which firms compete to quote prices and supply liquidity.

“Here’s an API. Bernard and 88 other people can market-make all these request-for-quotes (RFQs),” Marantelli says. “Some people might come in and just do esports because they’re esports experts. Others do everything. Some focus on same-game parlays. But it’s a sportsbook.”

The institutional layer is largely invisible to customers presented with a P2P proposition. Retail users may technically trade against one another, but the depth required by a mass-market product cannot be supplied by occasional customers alone. Professional firms must be prepared to quote continuously and commit substantial capital.

Each settlement involved cooperation with Kalshi’s investigation. 

What distinguishes Santos’ penalty is the exchange’s allegation that he actively issued false or misleading statements to alter prices and profited materially, violating additional rules such as failure to cooperate and manipulative conduct. 

These breaches escalated his sanction to a permanent ban and a significantly larger fine compared to others involved.
