About Jack Hammer 3

In 2025, Brazil collected almost BRL10 billion ($1.97 billion) in tax revenue from the licensed sector. In the first seven months of this year alone, BRL8.7 billion generated by the activity was delivered to public coffers. The Federal Revenue Service itself estimates that the sector should reach BRL16 billion in revenue during 2026.

Besides revenue collection, another concern is legal and economic. Companies have paid over BRL2.5 billion for licences since the sector’s regulation. Certainly, the end of the activity would lead to litigation to recover the amounts paid and compensation for investments made. Furthermore, the revenue from betting is already included in the Annual Budget Law and the Budget Guidelines Law, which define the priorities for federal government spending.

What worries the sector is not just the threat of drastic measures against legalised betting. So far, the government has consistently fallen short in its attempts to curb the illegal market, which still represents almost half of the segment.

“It was still very much a trading kind of UX,” he said of Kalshi at the beginning of the year. “The actual product offering has come a long way.”

Andrew Gonzalez, founder of prediction market infrastructure startup ParlayX, believes the ability of small teams to provide liquidity is one of the sector’s defining features. “Anyone can be a market maker,” he said. “You have these two- or three-man shops.”

Jefferies described market makers as the ecosystem’s “liquidity backbone”. They post executable bids and offers, manage inventory and provide prices when customer activity is heavily weighted to one side.

About Jack Hammer 3

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.
