About Diamond Vortex

My motivation for working at Calvinayre.com was having the privilege to work with some of the best creative minds in the gambling industry.

I want to thank Calvin for creating a platform that speaks to the gambling industry in a unique voice. He’s a guy who is not afraid to back his creative team, even in the face of a tough industry story. While Calivinayre.com is evolving, I will be following how he brings the same passion for business to the world of Bitcoin SV.

Calvinayre.com Editor-in-Chief, Bill Beatty – the Michael Kinsley of the gambling world. Bill just possesses that same rare gift of creating great writers. You won’t meet a more genuine guy that Bill, and I’m incredibly grateful for the opportunities to learn so much about the casino business, writing and how I see the world.

What is Diamond Vortex?

For all the hoopla surrounding prediction markets and expectations that the industry will eat away at sportsbooks’ NFL handle this season, the old guard industry is expected to control nearly 80% of pro football wagers this year.

Eilers & Krejcik Gaming (EKG) estimates that bettors will plunk down $40.5 billion on the NFL this season through regulated channels. Traditional sportsbooks are projected to capture $31.7 billion of that total, compared to a handle analog of $8.4 billion for prediction markets—a 79% to 21% split in favor of legacy operators.

Handle analog is a metric used as a cleaner comparison between sportsbooks and prediction markets because the latter’s volume doesn’t compare evenly with sportsbook handle.

About Diamond Vortex

In fact, behind those brands, a whole new sector is taking shape. Data and streaming suppliers, specialist market makers and technology companies are quickly invading the space.

The investment banking and capital markets firm Jefferies said in a September report that sports had become prediction markets’ “most important liquidity driver”, with combo and parlay-style contracts accounting for an increasing share of activity. But the analysts cautioned that prediction markets are scale businesses with relatively low revenue yields, leaving their economics dependent on sustained liquidity, engagement and trading activity.

James Monk, founder of sports data and streaming provider Catalist Sports, has witnessed that dependence directly. Catalist supplies ITF tennis data to Kalshi and Polymarket and has an exclusive US sports-streaming agreement with Kalshi.
