title: "AFOS · United Kingdom 2024 Electoral Divergence Dataset"
abstract: >-
Open dataset cross-referencing opinion polls and prediction markets for the United
Kingdom's 2024 general election (House of Commons, 4 July 2024), with explicit
poll-versus-market divergence rather than a blended average. Polls measure party vote
share; the market prices the probability of winning the most seats (first-past-the-post
plurality). On the eve of the vote the market gave Labour about 99% to win the most seats
while polls measured around 39% vote share; Labour won 411 of 650 seats on 33.7% of the
vote. Reform UK was third in votes (14.3%) but took only 5 seats, a gap the market priced
throughout. Poll figures compiled deterministically from public pollster releases (via the
Wikipedia aggregation); market odds from Polymarket.
