What is Opal Fruits?
“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.
That growth reflects the expanding number and variety of sports contracts. ITF tennis is particularly dependent on official data because its more than 60,000 annual matches are not generally televised. Unofficially monitoring a tour moving between locations such as Bogotá and Bali would be difficult, Monk noted.
About Opal Fruits
Greg Abel took over as CEO of the $1 trillion organization in early 2026. While Buffett continued to visit the office daily, he indicated he is now ready for a slower pace.
“Recently, I celebrated my 96th birthday with family and friends, including one of my great-grandchildren, who had just turned one. He’s moving a bit faster than I am these days,” Buffett wrote in a letter to shareholders. The billionaire credited Abel with exceeding his “sky-high” expectations, giving him complete confidence in completing the transition.
“The timing is right. I will become chairman emeritus and remain a director. My son, Howard, will succeed me as chairman,” Buffett told investors. “The company is in excellent hands, and I look forward to remaining a shareholder alongside you.”

One of the main concerns is Bill 560/2025, which is currently making its way through the council. The proposal prohibits advertising by betting companies at events in the city of São Paulo. This applies to events organised by public or private entities, whether for-profit or non-profit.
The bill prohibits signs, banners, or display panels in arenas, gymnasiums, stadiums and other sports event venues. It also bans advertising on public transport, such as the side panel, exterior or the rear window of buses. The bill imposes a fine of BRL50,000 ($10,000) and a ban on hosting events for up to two years.
The proposal does not explicitly prohibit the display of betting brands on team jerseys, but some city councillors want to include this in the bill.
