How to play London Tube
Friday’s opening was deliberately capped at 6,000 spectators while construction continues. Only the first two levels of the new five-story grandstand are currently open, with the remaining sections scheduled for completion ahead of next year’s meet.
The redevelopment was financed by a $455 million loan from New York State, approved in 2023. State officials have projected the project will generate $155 million in annual economic activity once fully operational, along with around $10 million annually in state and local tax revenue.
The redesigned complex features four distinct racing surfaces: a 1½-mile dirt track, two turf courses, and a one-mile Tapeta synthetic track.
What is London Tube?
The two companies began collaborating in November 2025. As part of the deal, Polymarket provided data for a dedicated prediction market section on Yahoo Finance. The feature provided market-based probabilities of economic, political, and financial developments alongside Yahoo Finance content.
The Yahoo Finance prediction market section was taken out in April. The companies have now confirmed that the larger deal is also off, as reported by Bloomberg.
Yahoo said Polymarket is still an advertising partner and suggested the two could collaborate on other projects in the future. Polymarket has not provided any public explanation for the end of the data partnership.
About London Tube
“In simple terms, what we have undertaken is a shift from machine-assisted human trading to human-assisted machine trading,” Lamb explains.
The shift means that rather than spending their time pricing and managing established markets, traders can now apply their expertise where human judgement has the greatest value, including developing and testing new products. AI removes many of the practical limits on what can be offered and priced, and manages the resulting scale and complexity. The result is greater efficiency for Kambi and a better service for its partners and their customers.
“To this point, sportsbook product creation has largely been guided by a trading department’s ability to profitably price and risk-manage certain bet offers,” Lamb says. “AI trading lifts those limitations, while also enabling that existing human expertise to be leveraged more effectively.”
