Kamakura

What is Kamakura?

The existence of a new competitor does not automatically mean sportsbook revenue will collapse. But valuations do not require proof of collapse to fall. A loss of confidence in future growth can be enough.

And now sportsbooks are joining the prediction market race themselves. DraftKings has moved into the market, while Flutter is also developing its presence. That could make prediction markets an additional source of revenue rather than a straightforward threat.

But it also requires investment at exactly the time shareholders are demanding better returns. Flutter’s recent results illustrate the tension. US adjusted EBITDA fell sharply in the first half of 2026, while the company continues to invest in FanDuel Predicts and other initiatives aimed at future growth.

How to play Kamakura

Unlike regulated sportsbooks, prediction markets allow customers between the ages of 18 and 21 to trade on sports-event contracts. Craig Carton, a sports talk host with WFAN 660 AM in New York, criticised the athletes for their endorsement of Polymarket. Carton, a recovering compulsive gambler, opined that the “unregulated” gambling markets are driving Americans into bankruptcy and kids out of school. Regulated books prohibit those under 21 from betting on their platform, leading Carton to question the celebrities for promoting the company.

“At what point does someone come along where you say no to the offer?” Carton asked.

A Bank of America study released on 1 September found that the median deposit account balance of households that participated in online betting was 59% higher than households that avoided the activity. As prediction markets rapidly expand alongside traditional sports betting, the findings have prompted “some to blur the lines between entertainment and investment”, according to a proprietary study undertaken by BofA.
