How to play Number King

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.

What is Number King?

Remote sports betting generated £2.4 billion ($3.2 billion), led by football at £1.2 billion ($1.6 billion) and horseracing at £769.3 million ($1.03 billion).

Despite the increase in remote GGY, new account registrations fell 3% to 32.4 million. There were 25.7 million active accounts at the end of the final reporting quarter.

Funds held in customer accounts also declined sharply. Operators held £886.6 million ($1.19 billion), down 13.9% from the same point a year earlier.
