Markets Retreat as Iran War Fears Push Oil Above $100; AI Agent Disruption Hammers Software Stocks

• S&P 500: -0.37%, NASDAQ 100: -0.77%, Dow Jones: -0.18%
• Oil surged above $100/barrel amid Iran war escalation and QatarEnergy declaring force majeure on LNG contracts
• Anthropic's new AI agent capabilities sparked a broad software sector selloff
• Trump's talk of Iran negotiations briefly lifted sentiment before markets reversed
• $580 million in suspicious oil trades before Trump's policy reversal drew Nobel laureate condemnation and market scrutiny

U.S. equities gave back gains from a prior rally on Tuesday, March 24, 2026, as the ongoing Iran conflict continued to weigh on investor sentiment and oil prices surged above $100 per barrel. The S&P 500 fell 0.37%, the NASDAQ 100 dropped 0.77%, and the Dow Jones declined 0.18% in volatile trading. Markets initially found support from President Trump's talk of negotiations with Iran, but that optimism faded as the session progressed.

Adding to the negative tone, Anthropic's announcement of new AI agent capabilities triggered a sharp selloff in software stocks, raising fears that autonomous AI agents could displace significant portions of the enterprise software market. The tech-heavy NASDAQ bore the brunt of the damage, with Palantir (PLTR) falling despite securing new government contract wins. Meanwhile, a Nobel laureate publicly labeled as 'treason' the suspicious $580 million in oil trades executed minutes before a Trump policy reversal, intensifying scrutiny of potential insider trading.

• Energy (XLE) +4.11% weekly — top performer by a wide margin, driven by oil above $100 and supply disruptions
• Financials (XLF) +0.64% weekly — outperforming amid rising rate expectations
• Real Estate (XLRE) -4.09% weekly — worst performer as higher energy costs and rates pressure the sector
• Utilities (XLU) -3.48% weekly — suffering from rising input costs and rate sensitivity
• Tech (XLK) -1.29% weekly — underperforming on AI disruption fears and software selloff
• Goldman Sachs highlighted top energy picks with significant upside and solid dividends

The weekly sector performance picture tells a clear story of a market rotating aggressively into war-beneficiary and inflation-hedge sectors. Energy (XLE) surged 4.11% over the past week, massively outperforming the S&P 500's -1.03% decline, as oil prices climbed on Middle East supply disruptions. Chevron (CVX) CEO warned that it will take time to recover from the Middle East production hit, underscoring the structural nature of the supply shock. Gas-related stocks also rose as supplies tightened following QatarEnergy's force majeure declaration on LNG contracts.

Financials (XLF) gained 0.64% and Materials (XLB) held near flat at -0.04%, both outperforming the broader market. Industrials (XLI) at -0.71% and Consumer Discretionary (XLY) at -0.80% also showed relative resilience. On the losing side, Real Estate (XLRE) plunged 4.09% and Utilities (XLU) fell 3.48%, reflecting the pressure from rising rates and energy costs. Communication Services (XLC) dropped 2.23%, caught in the broader tech downdraft.

General Motors (GM) jumped 5% following successful self-driving tests and an analyst upgrade, bucking the broader market weakness. Super Micro Computer (SMCI) rose despite regulatory scrutiny and analyst downgrades, with bullish analysts maintaining strong buy ratings on the AI infrastructure play. Broadcom (AVGO) received attention on multiple fronts — a $970 million contract from DISA and analyst coverage highlighting its $100 billion AI breakout potential — though the stock faced headwinds from the broader tech selloff.

On the downside, SoFi (SOFI) continued its slide, now down 35% with analysts acknowledging the bear case has merit. Freshpet (FRPT) shares were rocked by The Farmer's Dog launching at Walmart, introducing significant competitive pressure. FICO saw its stock decline amid pricing pressures, with J.P. Morgan trimming its price target. In the crypto space, Bitcoin hovered around $70,000 as crypto stocks plunged, though Bernstein maintained a $150,000 price target citing institutional adoption. A potential stablecoin yield ban under the Clarity Act deal sent Circle and the broader crypto market lower.

• QatarEnergy declared force majeure on LNG contracts, tightening global gas supplies
• CVX CEO warned Middle East production recovery will take significant time
• Private credit fears added a new dimension of risk alongside geopolitical concerns
• Analysts favor U.S. energy stocks and gold as beneficiaries of current macro environment
• Barron's cautioned that the market's downside trajectory may already be locked in

The Iran conflict remains the dominant macro risk, with oil prices breaching $100 and QatarEnergy declaring force majeure on LNG contracts — a significant escalation in energy supply disruption. The Chevron (CVX) CEO's warning that recovery from Middle East production losses will take time suggests the energy supply shock could persist well beyond any ceasefire. Analysts noted that U.S. energy stocks and gold could be major beneficiaries of the current environment.

Beyond geopolitics, private credit fears emerged as an additional market headwind, with multiple outlets flagging concerns about stress in the private lending market. The combination of oil-driven inflation, war uncertainty, and credit market stress creates a challenging backdrop for risk assets. Barron's warned that the stock market's fate may already be sealed, suggesting the current pullback could deepen before conditions improve.
