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

Prediction markets put the probability at 14%: Will Israel launch a ground operation in Iran by May 31, 2026. Currently, markets see this as unlikely (14% YES). Israel prepared to renew Iran war, awaiting 'green light' from Trump, Katz says.

What’s Happening

Recent statements from Israeli Defense Minister Israel Katz have escalated rhetoric regarding potential military action, with Katz declaring on April 23, 2026 that Israel is "prepared to renew the war against Iran" and is awaiting a "green light" from the United States to "complete the elimination of the Khamenei dynasty." This announcement follows a period of intense conflict, including a ceasefire with Hezbollah and ongoing missile exchanges, and comes as the Israel Defense Forces charged two Air Force soldiers with spying for Iranian intelligence on the same day. The probability that Israel will launch a ground operation in Iran by May 31, 2026 currently stands at 14%, reflecting market skepticism despite the hawkish posture from Jerusalem.

Contrasting with Israeli belligerence, retired U.S. Army Gen. David Petraeus, a former CENTCOM commander, warned on April 21, 2026 against a "risky" U.S. ground operation to seize Iran’s enriched uranium stockpile at the Isfahan nuclear complex, arguing that assassinating more Iranian leadership will not resolve underlying tensions. War Secretary Pete Hegseth declined to confirm whether U.S. forces would secure the site, citing operational security, while former President Donald Trump claimed Iran’s nuclear sites are "obliterated" and extended a U.S.-Iran ceasefire. These mixed signals from Washington create uncertainty about whether the U.S. would support or veto an Israeli ground incursion, a key variable in whether Israel will launch a ground operation in Iran by May 31, 2026.

The structural factor that will determine the outcome of this market is the degree of U.S. authorization, as Israeli officials have explicitly conditioned a renewed ground campaign on American approval. Meanwhile, Iran’s Islamic Revolutionary Guard Corps (IRGC) claimed the capture of two ships, and Lebanon’s Prime Minister accused Israel of war crimes, indicating a volatile regional environment that complicates any ground operation. Military planners are also set to discuss reopening the Strait of Hormuz in London, suggesting diplomatic channels remain active despite the saber-rattling. With the May 31, 2026 deadline approaching, the probability that Israel will launch a ground operation in Iran by May 31, 2026 hinges on whether the Trump administration provides the green light Katz demands, a decision that remains opaque.
