This market will resolve to "Up" if the official FTSE 100 Index closing price for FTSE 100 (UKX) on Monday, October 12, 2026 is higher than the official FTSE 100 Index closing price for UKX on the most recent prior trading day. This market will resolve to "Down" if the official FTSE 100 Index closing price for FTSE 100 (UKX) on Monday, October 12, 2026 is lower than the official FTSE 100 Index closing price for UKX on the most recent prior trading day. E.g., ordinarily, a market on Monday would refer to the previous Friday for its most recent closing price, unless that Friday were a market holiday, in which case it would refer to Thursday, or the next most recent trading day. If the two specified closing prices are exactly equal, this market will resolve 50-50. Note that all figures will be rounded to the nearest cent using standard rounding. If UKX does not trade at all during the regular session, the market will resolve 50-50. If either of the relevant days are shortened (for example, due to a market holiday schedule), the official closing price published by FTSE 100 Index for that shortened session will still be used for resolution. If either of the relevant days have no official closing price (for example, due to a trading halt into the market close, system issue, delisting, or other disruption), the market will use the last valid on-exchange trade price of the regular session as the effective closing price. The resolution source for this market is the Wall Street Journal, specifically the Close values published by the WSJ under "Historical Prices".

Currently, the odds on Polymarket for this market represent a collective prediction from traders. These predictions can be compared to traditional analyst forecasts, which often rely on economic indicators and company performance. It’s interesting to see if the wisdom of the crowd, as expressed through this market, aligns with or diverges from the expectations of financial experts regarding the FTSE 100’s direction. Do analysts predict the index will be up or down, and how confident are they in their assessments?
On Polymarket, this market is priced through a continuous auction mechanism where traders buy and sell contracts representing their belief about the FTSE 100’s direction. The price of these contracts reflects the probability of the outcome, with higher prices indicating a greater likelihood of the FTSE 100 closing up. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market’s price dynamically adjusts as traders react to new information and changing sentiment, creating a real-time assessment of potential market movement. This pricing is solely determined by supply and demand on Polymarket.
This market resolves around Oct 12, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the resolution will be based on whether the FTSE 100 closes higher or lower on October 12. The final closing price will be sourced from a widely recognized financial data provider. Traders will then be able to claim their winnings based on whether their prediction aligned with the actual direction of the FTSE 100 at the close of trading on that day.
Several signals and events could significantly move this market before Oct 12, 2026. Major economic data releases, such as inflation figures or GDP growth reports, could influence investor sentiment. Unexpected geopolitical events or shifts in global trade policies could also trigger market volatility. Company earnings reports from key FTSE 100 constituents will be closely watched, as will any statements from the Bank of England regarding monetary policy. Any surprise announcements or unforeseen circumstances could all contribute to price fluctuations in this market.
