  Wide spread — 14.0¢

  Bid-ask spread is wide enough that intraday moves overstate any tradeable advantage. Most of the headline pp move would be eaten by spread on a market order.

Each factor is grounded in a single named metric you can verify on this page — probability, volume, liquidity, signal, resolution state. No predictions, no prose hallucinations.

Keir Starmer is scheduled to participate in the Prime Minister's Questions (PMQs) in the Commons Chamber in the Palace of Westminster on every Wednesday. (https://www.parliament.uk/visiting/visiting-and-tours/watch-committees-and-debates/prime-ministers-questions/). This market will resolve to "Yes" if Keir Starmer says the listed term during the next Prime Minister's Question Time event he participates in. Otherwise, the market will resolve to "No". Any usage of the term regardless of context will count toward the resolution of this market. Pluralization/possessive of the term will count toward the resolution of this market, however other forms will NOT count. Instances where the term is used in a compound word will count regardless of context (e.g. joyful is not a compound word for "joy," however "killjoy" is a compounding of the words "kill" and "joy"). If this market requires a specified number of mentions of a person’s first or last name, a full-name mention will count as one mention (e.g., if a market is about “Joe / Biden 5+ times,” a mention of “Joe Biden” will count once). AI-generated audio or video will not count toward this market's resolution. If no such Prime Minister's Question Time event happens by May 31, 2026, 11:59 PM ET, this market will resolve to "No". If Starmer ceases to be Prime Minister for any length of time by May 31, 2026, 11:59 PM ET, this market will resolve to "No". This market is explicitly about scheduled events featuring Keir Starmer titled "Prime Minister's Question Time" (https://www.parallelparliament.co.uk/mp/keir-starmer/dept/cabinet-office/calendar). Speeches, events, or comments that occur outside of named, scheduled events will not qualify toward this market's resolution. If the event contains a Q&A, it will count toward the resolution of this market. The resolution source will be video of the events. Only remarks which are broadcast or streamed live will count toward this market's resolution.
