Which G7 leader will leave next?

**Stage 1 — Blind analysis (ignore market prices):**

- Situation overview: With no fresh news provided, we must rely on institutional rhythms (scheduled elections), historical turnover patterns, leader ages/health exposure, and typical domestic instability drivers. The question is which sitting G7 leader currently in office will be the *first* to leave office from the current moment onward. Leaving can occur via scheduled electoral defeat, resignation (political or personal), removal (confidence vote/impeachment), or death/serious incapacity.

- Institutional calendar and implications: - *France (Emmanuel Macron)*: France has a fixed presidential cycle; the next scheduled presidential election is in 2027. That timing makes Macron a near-term candidate to be the first to leave if he loses re-election or withdraws — the election is sooner than typical UK national elections. Historically French presidencies change in their election years fairly often. This gives Macron a material near-term exit risk. - *United Kingdom (Keir Starmer)*: If Starmer became PM in the most recent UK election (post-2024), the next legally latest general election is not immediate (UK maximum parliamentary term is five years but early elections are possible). Historically UK prime ministers can leave mid-term due to scandal or party revolt, but a comfortable majority and early-term honeymoon reduce short-term exit probability compared with leaders facing an imminent scheduled election. - *Germany (Friedrich Merz)*: Germany’s federal election cycle and coalition dynamics are important. If Merz is incumbent following a recent election, his risk depends on coalition stability — German chancellors can be removed via coalition collapse but scheduled elections define the predictable windows. Without a near-term federal election, risk is moderate. - *United States (Donald Trump)*: The next U.S. presidential election is 2028; barring extraordinary events (impeachment, resignation, death), a sitting president is more likely to remain in office until the next scheduled contest. Historically, presidents are rarely the first in a multi-country comparison to leave unexpectedly (assassinations aside). - *Mark Carney*: He is not a head of government of a G7 country (former central banker / public official). If included as a 'leader' on the market, his institutional position and contract length matter — central bank governors frequently change, but whether his office counts as a G7 'leader' for this event is ambiguous and lowers the informational clarity.

- Comparative likelihoods (qualitative): - Macron has the highest predictable near-term institutional trigger (2027 election). That alone makes him a strong candidate to be the first to leave among G7 leaders with a scheduled turnover close to the present. - Starmer’s risk is driven primarily by political scandal, a sudden loss of party confidence, or an early election; absent those, the default path is longer tenure. - Trump and Merz look less likely to exit first on purely calendar grounds (US in 2028, Germany not necessarily due soon) unless exceptional events intervene. - Carney’s inclusion injects event-definition risk: if markets treat his role as a likely early exit (contract end/appointment elsewhere), that could shift probabilities.

- Quantitative intuition (independent probability): balancing election schedules, institutional stability and historical frequency of mid-term exits, I estimate ~35% that the UK Prime Minister (Keir Starmer) will be the first to leave among the listed G7 leaders. This reflects moderate risk (UK PMs are vulnerable to domestic politics) but is tempered by the shorter, clear electoral horizon for France and relative insulation of the U.S. presidency.

**Stage 2 — Market calibration (look at market prices):**

- The market price (Yes ~98%) implies near certainty that the UK PM will be the first to leave. That valuation is extremely implausible absent a major, specific, contemporaneous story (e.g., resignation announcement, terminal scandal, health crisis) about Starmer. Given the provided context expressly notes *no current data*, the market is almost certainly mispricing this contract.

- Possible reasons the market is skewed so heavily toward 'Yes': - *Misunderstanding of event definition.* Traders may be treating a different definition of 'leave office' (e.g., leave any office at all, including non-head-of-state posts such as a central bank governor) or misread the
