About Blue Diamond
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.”
About Blue Diamond
The ASA reviewed a clip posted to TikTok in July promoting Midnite, a Gibraltar-based online casino app. The clip displayed a young-looking man using the app, accompanied by the voiceover: “Another massive World Cup upset. Bet £10 on the big match and get £30 in free bets. Level up your World Cup with Midnite, get on it.”
According to the ASA’s Code for gambling advertising, anyone who “was, or seemed to be, under 25 years of age” must not be depicted gambling or playing a significant role in advertisements.
The regulator concluded that the central figure’s youthful facial features, casual styling and excited demeanour gave the impression he was in his late teens or early twenties.
What is Blue Diamond?
Crash games like Aviator have become hugely popular because they are simple to understand and fast to play. A multiplier climbs from 1x and you decide when to cash out.
The key tension in every crash game is greed versus discipline. The multiplier can crash at any moment, so the longer you wait the bigger the reward but also the bigger the risk.
Many players use a fixed cash-out target, such as 1.5x or 2x, and exit automatically every round. This removes emotion from the decision and keeps losses predictable.
