**UK GDP growth for 2026 has shown resilience in the first half of the year, with quarterly expansions of 0.6% in Q1 and 0.5% in Q2, supported by strong services output and a pickup in business investment concentrated in AI-related areas such as software, data centers, and professional services.** This momentum has prompted upgrades in institutional forecasts, including the IMF’s recent revision to 1.3% for the full year—up from 1.0% in July—while the OECD projects 1.1% and the average of independent forecasters sits near 1.2%. These figures cluster firmly within the 1-2% range that commands the overwhelming majority of trader positioning on Polymarket. Elevated energy prices stemming from the Middle East conflict have begun to feed into higher inflation (CPI at 3.1% in August), prompting the Bank of England to hold its policy rate at 3.75% with hawkish signals for potential tightening. This dynamic, alongside the approaching October 28 Budget and OBR update, introduces downside risks that could moderate growth later in the year but have not yet derailed the central tendency around 1.2%. Market-implied odds reflect this consensus view of modest expansion amid contained but rising headwinds.
