The rise of platforms like Polymarket and CFTC-regulated Kalshi has brought election betting into the mainstream, with monthly trading volume across the sector hitting $24 billion in March 2026, up from roughly $5 billion in November 2024. While prediction markets remain controversial, they’re increasingly watched by Wall Street and political analysts for signals beyond traditional polling. Supporters argue the markets “aggregate information from a wider audience at a faster pace than polls”, though they aren’t infallible and can misprice events.
The trend isn’t limited to the UK. Prediction markets have drawn millions in bets on other elections globally, including more than $26 million tied to recent Indian assembly results. For the UK, the Labour lead mirrors broader polling and betting-exchange trends from the last general election cycle, when Labour was the firm favourite for a majority and Conservative seat losses were heavily backed. Resolution for the 2026 local elections market will be based on official council results once published, with a cutoff of April 30, 2027 if full results aren’t known by then.
Critics caution that turning elections into tradable contracts raises questions about market manipulation and election integrity, but regulators in the US have recently allowed such contracts to proceed after court rulings. For now, the markets are signaling strong confidence in Labour’s performance next May, and traders are positioning accordingly.
