This event tracks whether the UK Prime Minister will mention any of several major geopolitical, domestic policy, or political topics during the next Prime Minister's Questions session in the House of Commons. The topics monitored include international issues like NATO, Iran, Ukraine, and Israel, as well as domestic concerns such as NHS, immigration, and affordability.
Markets resolve based on whether Keir Starmer uses exact phrases or their plural/possessive forms during his official remarks at the next Prime Minister's Questions session occurring after June 10, 2026 at 11:00 AM ET. Grammatical and tense inflections beyond pluralization and possessives are not counted as variations. Plural nouns within proper nouns and noun phrases are included. Video of the session is the primary resolution source; official transcripts are used if video consensus cannot be reached. Promotional content aired during the event counts, but advertisements do not. Previously aired content, archival footage, and recordings from separate times or events are excluded. Resolution is based on Starmer speaking in an official capacity; inaudible private conversations or unofficial statements do not qualify. The event must be opened to the press for a live televised or streamed event to qualify.
Prediction market odds on Kalshi reflect aggregated trader beliefs and often diverge from traditional political analyst forecasts. While analysts may rely on prepared speeches, party strategy, and recent polling, prediction markets incorporate real-time information and financial incentives for accuracy. Comparing Kalshi odds to analyst commentary and political media coverage can reveal where the market sees higher or lower probability than expert consensus. This divergence often highlights overlooked risks or overconfident conventional wisdom about Starmer's likely statements.
On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, each potential statement or topic Keir Starmer may mention is priced as a separate binary contract, with odds reflecting the probability traders assign to that outcome occurring. Prices range from near zero to near 100, with tighter spreads on high-volume outcomes. Traders buy contracts they believe are underpriced and sell those they view as overpriced. The market price at any moment represents the marginal trader's assessment, updated continuously as new information arrives and positions shift.
The market resolves on Jun 25, 2026, following the conclusion of Prime Minister's Questions. Resolution is determined by whether Keir Starmer's actual statements during that session match the specified outcome criteria. Official parliamentary records, broadcast transcripts, and verified media reports serve as the authoritative source. Each contract settles to 100 if the statement or topic was mentioned and 0 if it was not, based on the exact wording and scope defined for that outcome at market creation.
Major political developments—such as breaking news, economic data, international crises, or parliamentary scandals—can shift expectations about Starmer's priorities during Questions. Opposition party announcements or leaked government agendas may signal which topics he will address. Recent Commons debates, media pressure campaigns, and public opinion shifts also influence trader forecasts. Starmer's own recent statements and party messaging provide clues about likely themes. As the session date approaches, final parliamentary schedules and pre-Questions briefings typically drive final odds adjustments.
