What is Mahjong for Seniors?
Personally, the journey at Calvinayre.com has been about the great people I’ve been lucky enough to work with. It’s a rare thing in the world to be able to find great people to work with. I want to thank two former bosses who encouraged me to chase my passions in this industry. AD, a former Calvinayre.com editor and T2 who took a chance on me as well.
I don’t know what I’m going to be doing next, but I know I want to stay in the casino industry. It’s an industry I always come back to and love.
Reach out anytime for a laugh, talk shop or share ideas. I can be found on Linkedin, Twitter, Facebook and Muckrack.

Three others, Polymarket, Crypto.com and Novig, saw gains of at least 30%, led by Polymarket with a weekly increase of 46%.
One interesting nugget surrounds weekend figures at Kalshi, where volume on Sunday only surpassed prior daily activity by $34 million, BofA data shows. Typically, Sunday volume for the quarter dwarfs that of College Football Saturdays due to the voracious demand for NFL offerings. BofA analyst Shaun Kelley attributes the irregularity to the possibility that Kalshi is “over indexing” on college sports.

Based on its projections, EKG sees the overall sports wagering industry growing 8% year-over-year, outpacing the current baseline growth rate of 5% (a figure that strips out temporary boosts from the 2026 World Cup).
Assuming that 8% spurt is realized, it’d be impressive because since the end of the 2025 football season, only Missouri and Alberta, Canada joined the live and legal sports betting party with Arkansas opening to DraftKings and FanDuel earlier this year.
Prediction markets have proven effective at attracting sharp bettors and high-rollers who are often limited or banned by traditional sportsbooks. However, consumer surveys indicate that when given the choice between a sportsbook and a yes/no exchange, most recreational bettors still prefer the traditional sportsbook interface. That dynamic helps explain why prediction markets remain in second place.
