Prediction market punters heavily back Wes Streeting as the next Chancellor

The article says betting markets on Polymarket are heavily favoring Wes Streeting to become Britain’s next chancellor, with a 70% implied chance by the end of 2026. The move follows Keir Starmer’s planned resignation, which is expected to trigger a Labour leadership contest and likely a cabinet reshuffle. Investors are watching closely because the next chancellor will signal whether fiscal policy stays disciplined or shifts toward looser spending. Brokers cited in the piece describe Streeting as relatively market-friendly, while noting concerns that a Miliband-led Treasury could raise borrowing risks. The market relevance is mainly to UK bonds and broader UK risk assets, as any perception of weaker fiscal restraint could pressure government debt and sterling sentiment.
