Will the 2026 United Left primary for the 2027 French presidential election be canceled?

Analysis

The ensemble mean of 27% is an artifact of averaging: three agents (Grok, Kimi, GLM) output 1%, but their own evidence sections are internally contradictory — Grok lists strong evidence UP (primary 'near KO', PS withdrawing, ~55-70% historical abandonment rate) yet outputs 1%, which strongly suggests a probability-direction error or misreading of the resolution polarity. Kimi and GLM at least anchor their 1% on the strict resolution criteria (4 committed parties just reaffirmed on July 2, so 3-of-4 withdrawal is a high bar), but 1% is indefensibly low given the acknowledged 'official cancellation' path and severe crisis reporting. The five substantive agents (GPT-5.5 at 41%, Opus at 40%, Qwen at 44%, Gemini at 48%, Fable at 40%) converge tightly around the market's 43.5% and share the same factual picture: (1) primary scheduled Oct 11 with 5 declared candidates; (2) media consensus post-municipals that it's 'mal engagée'/'near technical KO'; (3) decisive PS militant vote July 9; (4) Écologistes internally split with autonomous-Tondelier faction; (5) but strict resolution criteria and recent public recommitment by the 4 core parties cut against cancellation, and postponement doesn't resolve as canceled. The median (40%) is the better ensemble statistic here. Asking what I'd need to believe for the market to be wrong: I'd need either strong evidence the 4 committed parties will imminently formally withdraw (they just did the opposite) or evidence they'll certainly proceed regardless (contradicted by the crisis reporting). Neither exists, so the market price looks approximately efficient. My estimate of ~42% sits between the median and market, giving essentially no edge (<2%). With marginal edge, a binary event hinging on a party vote in days, and an ambiguous 'silent death vs official cancellation' failure mode, this fails the trade criteria. SKIP.

Key Evidence

The primary is officially scheduled for Oct 11 with declared candidates and a June 30/July 2 public recommitment by the 4 core parties, but the PS militant vote on July 9 and Les Écologistes' drift toward an autonomous Tondelier candidacy create genuine near-term collapse risk. Resolution requires an official cancellation OR 3-of-4 named parties withdrawing — postponement does NOT count.

Risks

The most likely failure mode may be a slow, silent death (postponement, reformatting, or a rump primary among smaller parties) that never triggers the strict resolution criteria — this asymmetry could make the true probability lower than the crisis headlines suggest.
