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.”

Again highlighting his view that this was a low-risk merger, Angelozzi described Spain and Italy as “among the best globally” in terms of markets.
Angelozzi observed particular opportunity in Spain, where he estimated Cirsa holds 6% of the online market, suggesting it’s more fragmented and less developed than in Italy.
“These two markets have been growing and will continue to grow very nicely [for] online, Spain even more than Italy,” he commented.
