Steve Eisman warns the Iran war is running the entire stock market right now
steve eisman says the Iran war is effectively steering stock-market behavior right now, describing it as a “unipolar market. ” The comments came on his podcast, The Real Eisman Playbook, as oil prices stayed above $100 and investors tracked disruptions tied to the Strait of Hormuz. The shift matters because it reframes what traders are watching most closely in the current tape: energy prices, escalation risk, and how long instability persists.
steve eisman calls it a “unipolar market” as $100-plus oil reshapes the focus
On The Real Eisman Playbook, steve eisman, the portfolio manager made famous by “The Big Short, ” said the Iran war is running the entire stock market right now, labeling it a “unipolar market. ” The phrase signals a market dominated by one force, with war-linked energy dynamics pushing other factors to the sidelines.
That framing stands out as a reversal from early March. At that time, steve eisman said on CNBC the conflict would be “very, very positive” and that he would not change a single trade. In the weeks since, the context has changed: four straight weeks of $100-plus oil was described as having altered the calculus behind that earlier confidence.
Oil’s historic surge and sector splits are driving day-to-day market positioning
Brent crude traded near $113 per barrel on Monday (time not specified beyond “Monday” in the available information). The same set of details described Brent as up roughly 55% in March, characterized as the largest monthly surge in the contract’s history, exceeding the 46% gain recorded during the first Gulf War in September 1990.
Inside U. S. equities, the move has shown up in stark sector performance. The Energy Select Sector SPDR Fund was described as the only S& P 500 sector in the green this month, while the United States Oil Fund was described as tracking crude’s historic March run. In practical terms, the market’s internal leadership is narrowing around energy as prices stay elevated.
Steven Cook: Strait dynamics, Gulf pressure, and fears of a prolonged “messy middle”
steve eisman’s guest was Steven Cook, senior fellow for Middle East studies at the Council on Foreign Relations. Cook said Iran is building a new transit regime in the Strait of Hormuz in which friendly vessels pass freely while adversaries are blocked. He said any deal that locks that in would be “a total disaster for the United States. ”
Cook also said Gulf states have communicated a clear message to Washington: they did not want the war, but now that it has started, they want it finished in a way that allows continued domestic transformation and “trillion-dollar bets” on their societies. Cook tied those priorities to projects including Saudi Vision 2030 and Abu Dhabi’s tech and finance pivot—efforts he said depend on stable energy exports and regional security.
Market-implied escalation risk and disruption timelines are front and center
Several market-style probability indicators were cited as part of the current risk picture. On Polymarket, bettors gave 71% odds that U. S. forces enter Iran by April 30, framed as a potential escalation. A separate Polymarket contract on regime change before 2027 was listed at 34%, described as traders pricing a grind rather than a swift collapse.
On Kalshi, odds that Strait of Hormuz tanker traffic normalizes before April 15 were listed below 12%, rising to 47% by June 1—implying at least two more months of disrupted flows through a chokepoint described as normally handling 20% of global crude. Kalshi’s recession market was also described as having jumped above 34%, its highest level this year.
What’s next: the next catalyst the market is watching
Cook predicted a “messy middle” three months out: a weakened but still dangerous Iran, Gulf states hardening defenses, and a larger American military footprint than anyone planned. If that outlook holds, the war premium in crude “isn’t unwinding anytime soon, ” and the next catalyst to watch was identified as how Iran responds to Trump’s latest threats against its oil infrastructure. For traders reading steve eisman’s warning, the near-term question is whether the Iran war continues to be the single dominant driver—or whether a shift in Strait conditions and escalation expectations loosens its grip on the market.
