About Happy Halloween
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.
How to play Happy Halloween
Two operators alone – Kalshi and Polymarket – topped the combined $1 billion mark in NFL trading activity over the first six days of Week 1, according to numerous measures this week. During the period, Kalshi recorded NFL volume of $983.4 million, according to DeFi Rate, earning the pole position by a large margin. Mahomes and the Kansas City Chiefs thrashed the Denver Broncos 31-10 on Monday Night Football, capping the largest week for prediction markets ever.
Even before the primetime matchup in Kansas City, it became abundantly clear that the industry would shatter previous marks for weekly activity. The AFC West showdown bolstered the already robust totals. Overall, volume for the week hit a record $15.9 billion, according to Bank of America, up 16% from a week earlier.
The pure-play prediction market-operators, Polymarket and Kalshi, emerged from Week 1 as the clear winners. On one hand, Kalshi’s market share lead narrowed over its competitors, falling to 82% for the week ended 13 September, down from 86% a week earlier.

“If we just sold the data to Kalshi in order to list the markets but no one was coming in and placing liquidity, there’s no point in them listing the markets,” Monk said. “We also need to supply the data to the market makers to inform their models.”
Catalist initially received a list of fewer than 10 potential market makers from Kalshi. It has since completed agreements with close to 20 and is engaging with approximately another 20.
That growth reflects the expanding number and variety of sports contracts. ITF tennis is particularly dependent on official data because its more than 60,000 annual matches are not generally televised. Unofficially monitoring a tour moving between locations such as Bogotá and Bali would be difficult, Monk noted.
