Local elections in London, UK are currently scheduled for May 7, 2026. This market will resolve according to the party that controls the most London borough councils as a result of this election. Control is defined as having more than half of the voting councillors of a London borough council. Any executive positions, like Mayor, will not count. A candidate will be considered an official candidate of a party if they are officially nominated by that party and are registered for the relevant election in affiliation with that party. Independent candidates will not count for any party.

A prediction market is a real-money contract that pays $1 per YES share if the stated outcome occurs, and $0 if it does not. The current price is therefore the crowd's probability estimate — set by thousands of traders competing in a live order book, not a bookmaker. PolyGram routes your order into the same Polymarket venue, adds an email-first login and USDC deposits, and settles on Polygon within minutes of the result.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
