How to play The Great Stick Up

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.

DraftKings is a different proposition. Its share price went from $43.30 on 18 September 2025, to $21.75 upon market closure last week. Beynon says it “arguably offers the greatest operational upside if it can continue converting strong customer growth into sustained profitability”. Its prediction market strategy could also become an advantage if the new market proves complementary to sportsbook betting.

MGM Resorts International’s investment case is supported by Las Vegas, regional casinos, property assets and its 50% interest in BetMGM. Its own share price has been on a different journey to its online pureplay peers, having increased by 5% in a year, to $37.81 on 18 September.

Marantelli identifies White Swan and Susquehanna as two firms operating at industrial scale in parlays, with Jump Trading, Mojo and DL Trading among the possible leading group. Below them are numerous smaller syndicates, some managing between $5 million and $10 million, alongside sports-specific specialists.

James Monk, founder of sports data and streaming provider Catalist Sports, has witnessed that dependence directly. Catalist supplies ITF tennis data to Kalshi and Polymarket and has an exclusive US sports-streaming agreement with Kalshi.

The company must also provide data to the firms making markets on those events.

“If we just sold the data to Kalshi in order to list the markets but no one was coming in and placing liquidity, there’s no point in them listing the markets,” Monk said. “We also need to supply the data to the market makers to inform their models.”
