How to play Blade And Fangs
Flutter has arguably the strongest online franchise of the four. Its share price fell from $282.33 on 18 September 2025, to $89.56 on 18 September this year, with a market valuation of $15.54 billion.
FanDuel remains the leading US sportsbook, while Flutter’s international businesses provide additional sources of growth. But that quality comes with high expectations.
Beynon describes Flutter as “the highest-quality online betting franchise globally”, with FanDuel’s leadership position providing “significant long-term value”. The problem is that the market is increasingly questioning how much future earnings growth can be generated from that position as the industry matures.

“Just better margins,” he says of that decision. “I think it’s more defendable. It’s the area that fewer people can do well. So I think it’s more defendable margin, more ability to get long-term contracts and beneficial positions.”

What is Blade And Fangs?
Given the rise of prediction markets, this week arguably represents the most frenzied campaign since the historic PASPA decision in 2018. Buttressed by massive capital injection from substantial funding rounds, operators have spent handsomely on celebrity endorsements. Over the last week, ads featuring LeBron James, Sydney Sweeney, Marshawn Lynch and Jeremy Piven have showered the airwaves. Even Pete Sampras, who disappeared from the public spotlight for the better part of two decades, resurfaced in a US Open spot for Kalshi.
While Polymarket pulled off a coup with the signings of James, Eli Manning and Derek Jeter, a Novig ad featuring Sweeney arguably received as much fanfare. Sweeney, an Emmy Award-nominated actress known for her role in HBO’s Euphoria series, stars in the spot titled “Just Sports.” As of Friday afternoon, the Novig post on social media platform X received at least nine million views.
Throughout the ad, Novig throws shade on its rivals for offering niche markets on events such as the timeframe for when traders believe that Venezuelan President Nicolás Maduro will be removed from office. Unlike operators such as Kalshi and Polymarket, Novig has opted to limit its offerings to purely sports. “No betting on wars, or deaths…or politics,” Sweeney mused.
