About Queen Treasure
Strip away the language of contracts, order books and event trading and Bernard Marantelli has a blunt description of what is happening inside US sports prediction markets. “Kalshi is a sportsbook that’s just not allowed to have an in-house risk team,” says the founder of White Swan Data, one of the specialist firms now making markets on prediction exchanges.
The difference is all about the risk function. A sportsbook employs traders to price bets and manage its exposure. An exchange provides an API through which firms compete to quote prices and supply liquidity.
“Here’s an API. Bernard and 88 other people can market-make all these request-for-quotes (RFQs),” Marantelli says. “Some people might come in and just do esports because they’re esports experts. Others do everything. Some focus on same-game parlays. But it’s a sportsbook.”

Yahoo Finance has soured on prediction market Polymarket, closing a deal between the financial news platform and the event contract operator in less than a year after it began.
The two companies began collaborating in November 2025. As part of the deal, Polymarket provided data for a dedicated prediction market section on Yahoo Finance. The feature provided market-based probabilities of economic, political, and financial developments alongside Yahoo Finance content.
The Yahoo Finance prediction market section was taken out in April. The companies have now confirmed that the larger deal is also off, as reported by Bloomberg.
