TL;DR

US equity markets climbed toward all-time highs on May 8, 2026, even as US and Iranian forces exchanged fire in the Strait of Hormuz. The Nasdaq Composite rose 0.66%, the S&P 500 gained 0.41%, and the Dow Jones added 0.37%. The resilience came from two sources: a blowout April jobs report (115,000 added vs. 65,000 expected) and market belief that the US-Iran peace deal is still alive. Understanding why stocks are staying risk-on matters because it shapes the weekend gap risk and the setup heading into next week.

Stocks Surge Despite US-Iran Hormuz Exchange

US and Iranian forces traded fire in the Strait of Hormuz on May 8 - Day 70 of the conflict that began February 28. US Central Command said it conducted defensive strikes after Iranian forces attacked three US Navy destroyers moving through the waterway. Iran accused Washington of violating the April ceasefire. Brent crude briefly spiked almost 3% to roughly 03 before settling near 00-01 as President Trump insisted the ceasefire remained in effect.

By any historical standard, a military exchange in the world's most important oil chokepoint should have sent equities lower. Instead, the S&P 500 and Nasdaq held near record territory set earlier this week. That divergence is the story for equity traders today.

Why Equity Markets Are Staying Risk-On

Three distinct forces are keeping stocks elevated despite the Hormuz flare:

1. A Blowout Jobs Report

The Bureau of Labor Statistics reported Friday morning that the US economy added 115,000 jobs in April - nearly double the 65,000 economists had forecast. That is a significant beat in a war economy where most models expected the Iran conflict's supply-side disruptions and energy cost pass-through to weigh on hiring. The number signals the US labor market is more resilient than feared, supporting consumer spending expectations and reducing the probability of a near-term recession.

2. Peace Deal Still Alive

Trump's statement that "we're negotiating with the Iranians" - delivered even after the exchange of fire - told markets that the diplomatic channel is intact. Iran's state media separately reported the situation was "back to normal now" within hours of the incident. As long as peace talks remain viable, the market is pricing in an eventual reopening of the Strait of Hormuz and a normalization of energy supply. That forward expectation provides a floor under equities.

3. AI and Tech Earnings Momentum

Earlier this week, Advanced Micro Devices (AMD) reported strong results that sparked a broader AI-related rally, pushing the S&P 500 and Nasdaq to fresh closing records on Wednesday. That momentum has not unwound. Tech and AI-linked names continue to trade on earnings and forward guidance rather than on geopolitical risk. When the growth engine of the market is firing on its own fuel, it takes more than a contained military exchange to redirect sentiment.

Implications for Equity and Futures Traders

Stock Traders

The current setup rewards traders who can separate signal from noise. The Hormuz exchange is real and important, but the market is telling you it is a negotiation-phase incident, not a conflict-expansion event. The sectors worth watching are energy (XLE, oil majors) which benefit from 00+ oil, and defensives which attract rotation if the geopolitical situation deteriorates further. Technology and growth names are likely to remain the primary drivers of index direction as long as earnings hold up and the peace deal stays technically alive.

Equity Index Futures Traders

Weekend gap risk is elevated. If Iran rejects the US peace proposal or another military exchange occurs before Monday's open, equity futures could open lower Sunday evening. Conversely, a constructive diplomatic signal from Tehran over the weekend would likely produce a gap higher, particularly in energy-sensitive names. Traders holding over the weekend should have a clear view of which scenario they are positioned for.

Macro Context: The Fed and Rate Expectations

The jobs beat complicates the Federal Reserve's position. Strong labor data reduces urgency to cut rates, while oil above 00 sustains inflation. Markets are now navigating a tighter-for-longer Fed in a war economy - a combination that historically favors value and energy over long-duration growth, yet the current rally is led by growth. That tension bears watching as the earnings season winds down.

Potential Positives vs Negatives

Potential Positives

  • Jobs resilience reduces recession risk: A 115K beat in a conflict-impacted economy signals that the labor market is absorbing the war's economic shocks better than models predicted. That reduces one of the key tail risks that could derail the equity rally.
  • Diplomatic channel intact: As long as Trump insists negotiations are continuing, the market can maintain its base case that oil eventually normalizes and the supply shock ends. A peace deal announcement - even a preliminary one - would be a significant positive catalyst for equities and a headwind for energy.
  • AI investment cycle independent of geopolitics: The technology sector's earnings-driven momentum is not directly tied to Hormuz outcomes. Semiconductor and software capex cycles are driven by enterprise AI adoption, not oil prices, giving the Nasdaq a durable tailwind regardless of short-term geopolitical noise.

Potential Negatives

  • Weekend gap risk is real: Equities are priced for a peace-deal base case. Any deterioration over the weekend when markets are closed creates asymmetric downside risk. A failed negotiation or renewed escalation would likely produce a sharp gap lower on Monday.
  • Inflation stickiness limits Fed flexibility: Oil above 00 keeps inflation elevated and constrains the Fed's ability to cut rates even if growth slows. This stagflationary backdrop is not reflected in current equity multiples, which are priced for a soft-landing scenario.
  • Breadth concentration is a vulnerability: If the AI-led rally remains narrowly concentrated in a handful of large-cap tech names, any negative earnings revision or valuation reset in that group could pull the index lower even if macro conditions are stable.

What Could Happen From Here

Base Case: Stocks Hold Near Highs Into Next Week (50-55% probability)

Peace talks continue over the weekend, no new military incidents occur, and equities open Monday near current levels. The Nasdaq consolidates below recent records while the next catalyst - likely a Fed speaker or further Iran diplomatic news - sets the next directional move.

Confirms: No new Hormuz incidents by Sunday; Trump or State Department comments reinforce the diplomatic track.
Invalidates: Another exchange of fire or Iran formally rejecting the US peace proposal.

Upside Case: Peace Deal Progress Triggers Rally (20-25% probability)

Iran engages constructively with the US framework over the weekend. Brent crude falls toward 5-90 on peace expectations. Energy-sector profits compress, but rate-cut expectations revive and growth/consumer names rally hard. A full reopening timeline would be the most significant bullish catalyst for equities since the conflict began.

Confirms: Iranian foreign ministry signals acceptance of core deal terms or Trump announces high-level direct talks.
Invalidates: Iran attaches non-starter conditions or hardline factions publicly oppose any settlement.

Downside Case: Weekend Escalation and Monday Gap Lower (25-30% probability)

A second exchange of fire over the weekend, or Iran formally announcing the ceasefire is void, breaks the market's base case. Equity futures open Sunday evening sharply lower. Oil spikes, volatility (VIX) jumps, and defensives outperform. The week's record-high prints become a near-term resistance zone.

Confirms: CENTCOM announces additional defensive strikes; Iran makes a public statement declaring the ceasefire over.
Invalidates: Weekend silence with constructive diplomatic statements from both sides.

FAQ

Why are stocks going up when there is literally a war near the world's biggest oil chokepoint?
Markets are forward-looking. Investors are pricing in the probability that the current conflict ends with a peace deal, which would normalize oil prices and remove the supply shock. As long as that expectation holds - supported by Trump's comments that talks are ongoing - stocks can continue to trade on earnings and growth fundamentals rather than the day-to-day military situation.

What would change this picture?
The key scenario that would flip market sentiment is a formal breakdown in peace talks or an escalation that directly threatens Gulf oil infrastructure beyond the Strait. As of Friday afternoon, neither has occurred. The jobs beat also provides a buffer - a strong labor market reduces the recession risk that would otherwise compound the geopolitical stress.

What to Watch Next (24-48 Hours)

  • Iran's response to the US peace proposal - Any signal from Tehran - acceptance, rejection, or counter-proposal - before Monday's open will directly set the equity market tone for the week.
  • Trump statements over the weekend - Watch for any tone shift from "We're negotiating" toward more aggressive language, which would increase the probability of fresh military action.
  • Brent crude at the Sunday open - Whether oil holds near 00 or moves sharply in either direction will be the first signal before equity markets open.
  • AMD and tech follow-through - If semiconductor stocks and AI names hold their gains into Monday, the earnings-driven rally has legs independent of the geopolitical situation.
  • Fed speakers - Any commentary on the jobs beat or inflation outlook could shift rate-cut expectations and provide an additional catalyst for equities early next week.
