How to play Gemstone

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.”

SmartSoft maintains an established and growing presence in Africa, having also co-hosted the iGB L!VE Africa Summit in July.

Through its membership with AiA, SmartSoft will participate in events such as regulatory discussions, strategic roundtables and research initiatives, alongside other operators and suppliers in the market.

Post-World Cup, Kambi is now working to offer more shots-on-target options before matches and additional automated intervals in-play, creating further betting opportunities as games unfold.

“Giving bettors more ways to personalise their wagers around the players and moments they care about was a big takeaway from the tournament and one which continues to inform Kambi’s development of cutting-edge sports betting products,” Lamb says.

Kambi is now rolling out AI trading across other sports, including basketball, ice hockey and American football. Its longer-term ambition extends beyond automating established processes to using the technology to create products that could not previously be delivered at scale.
