About The Knight King

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.

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.

What is The Knight King?

It coincided with the beginning of the NFL season in the US, viewed as a peak commercial period for sports data monetisation. Genius also maintains partnerships with DraftKings and FanDuel, both of which signed extensions to remain as NFL partners ahead of this season.

Citizens gaming analyst Jordan Bender wrote in a 16 Sept. note that with the NFL season now under way: “Genius should benefit from increased spending across both traditional sports betting and the emerging prediction market industry.”

Added Bender: Genius’ recent deals with Kalshi and Polymarket “have provided an incremental positive catalyst for [Legend founder] Mr Kisberg and team”.

What is The Knight King?

The Yahoo Finance prediction market section was taken out in April. The companies have now confirmed that the larger deal is also off, as reported by Bloomberg

Yahoo said Polymarket is still an advertising partner and suggested the two could collaborate on other projects in the future. Polymarket has not provided any public explanation for the end of the data partnership. 

The news comes as prediction market operators continue to form alliances with major media outlets. These deals allow news outlets to embed event contract data into their reporting and offer prediction platforms more visibility to investors and news audiences.
