What is Ruff Heist?

“He steps into the interim role supported by an experienced finance organisation and I am confident that our reporting, controls and capital markets work will continue without disruption.”

Bally’s shares plunged 26% on 17 August despite a solid Q2 in which group revenue rose by 20% year-on-year to €792.2 million.

The share price came under pressure following debt disclosures in Bally’s Q2 10-Q filing, which was submitted to the Securities and Exchange Commission on 14 August.

How to play Ruff Heist

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.”
