London's 2026 borough council elections will see all 32 councils hold simultaneous elections—a significant moment for local governance across the city. These three prediction markets focus on the primary outcome: which party will control the most London councils? Labour, the Liberal Democrats, and the Green Party represent the main contenders being tracked here. Unlike general elections, local council elections often turn on community-specific issues rather than national politics. Voter priorities around housing, transport, social services, and environmental policies shape local results in ways that can diverge notably from national polling. The markets below show real-time probability estimates for each party outcome, reflecting the aggregated views of prediction market participants who have financial incentive to forecast accurately. When examining these prices, consider how local election results historically vary from national sentiment—strong local campaigns, well-regarded candidates, and borough-specific concerns can shift outcomes substantially. Turnout patterns also matter; local election participation typically differs from general election turnout, often favoring certain constituencies. By observing all three markets simultaneously, you can track how competitive pressure flows between outcomes: as one party's probability rises, which others fall, and by how much? These markets offer a forward-looking lens on council control, distinct from polling snapshots.
