What is Dr Feelgood?
Santos is not the only individual disciplined for trying to game the prediction market system. Ben Midgley, a Republican candidate for the governorship of Maine, admitted purchasing under $1,000 worth of contracts related to his campaign. He accepted a $5,434.30 fine and a three-year suspension.
Meanwhile, Laurie Buckhout, a candidate for a North Carolina congressional seat, was fined $2,589.96 and suspended for three years after buying under $1,000 of contracts linked to her race.
Also, Stephen Cloobeck, a billionaire and 2026 California gubernatorial candidate, purchased approximately $10,000 in contracts tied to his campaign. He was fined $31,770 and suspended for three years.
About Dr Feelgood
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.
Streaming is also becoming part of the product. Monk said prediction market interfaces had moved beyond their earlier trading-led presentation to incorporate streams, player propositions and combinations resembling sportsbook bet builders.
About Dr Feelgood
“Customers seek personalised experiences, extensive player proposition bets and the ability to build highly customised wagers in real time,” Lamb says. “Meeting these modern expectations through manual trading is no longer realistic at scale.”
AI also helped Kambi reduce the delay between a customer selecting an in-play bet and being able to place it. Its dynamic live delay technology enables it to set bespoke live delay on an individual bet level, optimising the UX and alleviating friction. Across the Premier League and World Cup, Kambi reduced live betting delay by more than 40% between August 2025 and July 2026.
The result for customers was more choice, shorter suspension periods and faster bet acceptance. For operators, those improvements can support both customer retention and profitability.
