How to play Book Of Kings

Financial advisors continue to urge consumers to view sports wagering strictly as entertainment and to only risk funds they can afford to lose.

Research from Stanford University published in April concluded that sports bettors remain “overoptimistic,” generally expecting to break even despite losing an average of 7.5 cents on every dollar wagered.

“Overoptimism is largest among bettors who partake in a complex type of bet known as a parlay,” the Stanford researchers wrote. “Compared to other forms of betting, parlays are more likely to be driven by bias.”

What is Book Of Kings?

When I joined CalvinAyre.com in August of 2009, there was an enormous gap in the industry for an honest, transparent news site with regular, fresh video content. Over time, we grew from a tiny team of a handful of people to dozens, providing the industry with the juiciest breaking news and cutting-edge video coverage. 

Today we pass on the torch to our event organizing and media production friends who have more recently developed outstanding news coverage and video teams dedicated to the gaming space, hopefully who I’ll be seeing at CoinGeek Conferences in the future.

Reflecting on my fateful words at EiG back in 2013, it was the entrepreneurial energy, the innovation and the excitement surrounding Bitcoin that originally drew me to it. Back then, the obsession about Bitcoin was not related to price, it was about the disruptive technology and this is what meant something to me. While a great deal has changed in Bitcoin between 2013 and now, the energy, innovation and excitement are all still there and I am looking forward to the next chapter of my career with Calvin Ayre and the Ayre Media team.

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.
