What is Gem Elevator?
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.
Enda Kendrick, chief executive of service provider Veltium, similarly says the largest UK and European sharp-betting groups have moved rapidly into US prediction markets. He believes there are also more than 100 smaller operations, ranging from individual traders to teams of around 10, interested in entering the regulated US market.
Yet the presence of professional counterparties complicates the customer-facing idea that prediction markets merely allow users to trade opinions with one another. As Kendrick puts it, two ordinary customers are not going to place $10 million or $20 million behind the Philadelphia Eagles. Markets at that scale require institutions.

Clubs fear the measure will jeopardise revenue from betting company sponsorships. Corinthians (Esportes da Sorte), Palmeiras (Sportingbet), and São Paulo (Superbet) alone hold contracts worth BRL350 million annually with betting firms.
One concern is the measure might force clubs to host matches outside the city to maintain their advertising agreements.
Stakeholders have yet to determine their response to the bills, with educational campaigns and collective actions on the agenda. Coordination with political leaders in the city of São Paulo is also under way.

The lesson is simple: gambling still attracts capital when the money is visible. It is less attractive when the payoff lies far in the distance.
The biggest new uncertainty in US sports betting is prediction markets. The American Gaming Association estimates that Americans will legally wager $29.5 billion in betting handle through US regulated commercial sportsbooks during the 2026 NFL season, broadly unchanged from the $29.4 billion handle recorded in 2025. These figures refer to the amount wagered, not sportsbook revenue.
Robinson calls prediction markets “the main event”. His argument is not simply that US customers are moving from sportsbooks to prediction markets. The more important point is that sportsbooks no longer have the relatively protected market that was once assumed.
