About The Ruby

While sports event contracts are currently the tentpole category for the prediction market industry, data indicate bettors and traders are embracing other categories.

Fullstory points out that while 62% of consumers have dabbled in sports event contracts, 42% traded economic or financial derivatives on a prediction market while a comparable percentage transacted in an election or political event contract. More than a quarter traded at least one entertainment or pop culture derivative.

That widening breadth is vital for the industry at a time when some analysts estimate volume could jump to $10 trillion by 2035 – a projection that is largely rooted in other categories surpassing sports for the top spot.  

About The Ruby

I want to thank Derek Tonin, my editor who I would speak with every day I worked at Calvinayre.com. I’m grateful for the opportunity I have had to work with Derek. He’s an editor who doesn’t shy away from the blunt criticism and its inspiring being on the other end of the call. He’s a guy you would want in the foxhole right next to you, someone who isn’t afraid to give the blunt truth and also celebrate the wins with you.

There’s a huge team of writers, video editors and IT developers who have made Calvinayre.com this huge success. Raise a glass to them, they have helped turn this site into the success that it is.

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.

About The Ruby

If it strikes a more reasonable balance that encourages economic development, “you will see the world’s best casino operators submit proposals”, he says. The government, he adds, must show it is prepared to give developers enough room to manage the risks of committing billions of dollars in capital.

Klebanow remains cautious about the commercial prospects of Japan’s emerging IR market, particularly given the tight limits on gaming capacity. With only five casinos ultimately envisaged, he argues that the number of gaming machines and tables will be modest relative to Japan’s population, making it “very safe to assume” that gambling will be socially and physically contained.

The bigger question, therefore, is whether such constraints will leave operators enough capacity to generate the returns needed to justify their investment.
