Will Israel launch a ground operation in Iran by May 31, 2026?

Israeli decision-makers (Netanyahu, IDF leadership) have explicitly rejected large-scale ground incursions into Iran and focused operations on Lebanon/airstrikes; no incentive or logistical capability exists to reverse this in the final 8 days. Recent behavior (ongoing air campaign + ceasefire talks) and base rates (zero prior Israeli ground ops inside Iran) align with No resolving. Consensus-priced No (95.9%) has no plausible flipper before deadline.

Rules require official IDF confirmation or overwhelming credible consensus of Israeli military ground troops operating inside Iranian territory on/after 2026-02-28; enrichment explicitly states ongoing ops are airstrikes only, ground activity limited to Lebanon, and Israeli/U.S. leaders have rejected ground incursions into Iran, with only unconfirmed special-forces rumors. No qualifying evidence exists or is structurally possible by the 2026-05-31 deadline, satisfying the consensus-No case with no plausible rule-based flip. Analyst's recommended side (No) aligns directly with the literal criteria.

Consensus No at 95.9% with $547k total volume (substantial weekly flow implied), tight effective spread, and 1w/1m Yes price drift lower (-2.9pp/-8.5pp) on no counter-flow. Smart-money whales (4 on No vs 2 on Yes, $14k+ stake, 0.82 confidence) aligned with No; no opposing high-confidence insiders. Recent news confirms only airstrikes/prep for strikes + Lebanon ground ops, zero verified Israeli ground presence in Iran through May 23. Microstructure fully consistent with near-certain No resolution by May 31.
