3% — the median of 6 frontier models, resolving by 2027-04-19.

Answer

Gemini (Google): 2% — Lagarde has consistently disavowed running, leaving her without the domestic campaign apparatus needed to rival Philippe or Le Pen. Her ECB term runs through October 2027, and she has repeatedly ruled out entering French electoral politics. Macronist and center-right lanes are already crowded by declared figures like Édouard Philippe and Gabriel Attal. An announcement by early 2027 backed by Macron's coalition would dramatically raise these odds, but base rates for non-politicians are tiny.

Answer

Claude (Anthropic): 3% — Lagarde hasn't declared candidacy and would need to resign ECB post, enter a fragmented field, and win against entrenched RN/left rivals. No formal candidacy announced as of Oct 2026; speculation alone rarely converts to candidacy this late before an April 2027 vote. Polls consistently show RN's Le Pen/Bardella and left figures far ahead of any centrist alternative to Macron's bloc. Even if she ran, centrist candidates face a crowded, fractured field and historically underperform against polarized front-runners.

Answer

GPT (OpenAI): 2% — It turns chiefly on Lagarde entering the race soon and displacing established centrist contenders before first-round voting. Lagarde would need to leave the ECB, build a party and secure endorsements by early 2027; no declared candidacy exists as of October 2026. French presidential winners almost always emerge from parties or long-running national campaigns; late technocratic entries rarely win outright. I would raise this sharply if she announced before year-end with a major bloc's backing and polled into the runoff places.

Answer

Grok (xAI): 8% — Lagarde must still declare, unify Macronists, and beat RN in a runoff. No announcement by late Oct 2026 leaves her outside the field; Attal/Philippe already occupy the center. Late non-politicians almost never win (Macron declared 16 months out); RN first-round lead is the base case. A Macron endorsement plus her ECB exit before April would be the only path that moves this above single digits.

Answer

DeepSeek (DeepSeek): 3% — Lagarde has shown no sign of running, and the filing window is nearly closed. Lagarde has never declared a candidacy and the filing deadline for the 2027 race falls in early 2027, leaving little time to build a national campaign. French presidential races are dominated by established party machines; no ECB president has ever resigned mid-term to run, and Lagarde's term runs to 2027. Centrist polling for a Lagarde candidacy has been minimal, while Le Pen, Bardella, and left-wing figures consistently lead; a Macron-backed alternative would likely…

Answer

Qwen (Alibaba): 2% — Lagarde has no party, no elected base, and would need to quit the ECB mid-term to campaign—essentially unprecedented. No unelected technocrat has ever won the French presidency; she'd need to build a party from scratch by early 2027 with no existing apparatus. Her ECB term runs to October 2027; resigning months early to campaign would be institutionally extraordinary and she has shown no signal of doing so. Even Macron, who had ministerial visibility and 18 months to build En Marche, was considered a longshot; Lagarde has neither advantage.
