What is Rainbow Mania?

The company must also provide data to the firms making markets on those events.

“If we just sold the data to Kalshi in order to list the markets but no one was coming in and placing liquidity, there’s no point in them listing the markets,” Monk said. “We also need to supply the data to the market makers to inform their models.”

Catalist initially received a list of fewer than 10 potential market makers from Kalshi. It has since completed agreements with close to 20 and is engaging with approximately another 20.

The UK government increased Remote Gaming Duty (RGD) from 21% to 40% from 1 April. Then from April 2027, a new 25% General Betting Duty rate for remote betting will apply, although remote bets on UK horse racing are excluded from the new rate.

Entain said the higher RGD had a £56 million negative impact on first-half EBITDA. In Britain, operators are dealing with government policy and higher taxes. In America, the main threat is competition. The problems are different, but they hit the same group of stocks.

Entain is trying to respond by simplifying itself. It has agreed to sell an initial 20% stake in Entain CEE for €425 million, implying an enterprise value of about €2.1 billion. The company says proceeds from the transaction and any future exit will be used to reduce debt and, subject to leverage objectives, return excess capital to shareholders.

Kenneth Brincat, CEO of the MDIA, said companies needed “practical ways” to better understand where AI fits within their businesses.

“Trust is fundamental to the responsible adoption of AI. As its use becomes increasingly embedded across the gaming sector, organisations need practical ways to understand where AI is being used, manage the associated risks and ensure that accountability and human oversight remain firmly in place,” he said.

“The AI gaming charter translates these principles into practical, sector-specific guidance,” he added.
