The Session

Wednesday closed as one of the more decisive geopolitical trading days in recent memory. The Dow Jones Industrial Average shed 800 points. The S&P 500 and Nasdaq each fell roughly 1%. Crude oil surged. The catalyst was blunt: President Trump declared the U.S.-Iran ceasefire 'over' and signaled imminent military action, and markets repriced risk within minutes.

The session's defining feature was not the size of the equity decline — a 1% S&P 500 drop is painful but not catastrophic — but the sharpness of the divergence it created. Energy stocks moved in the opposite direction from almost everything else. The geopolitical shock that punished growth-sensitive assets simultaneously handed commodity producers a windfall.

Winners and Losers

ExxonMobil (XOM) was the session's most prominent beneficiary. The company disclosed that its second-quarter profit outlook has improved by nearly $4 billion compared to prior expectations, driven directly by the oil price rally that followed the ceasefire breakdown. Exxon did acknowledge some production losses in the Middle East — conflict zones carry operational risk even for companies that gain from higher prices — but the price tailwind clearly outweighed the disruption. The update is a preview of what could be a broadly stronger quarter for the energy sector if crude remains elevated.

Semiconductors bore the brunt on the other side. Nvidia (NVDA), Micron (MU), and AMD (AMD) all fell sharply, continuing a pattern of chip stocks absorbing outsized losses whenever macro sentiment deteriorates quickly. The sector has no direct Iran exposure; the selling reflected a broader retreat from high-multiple, growth-sensitive names when geopolitical uncertainty spikes.

Nvidia's decline was particularly notable in context. The stock has now shed roughly $1 trillion in market capitalization from its peak, and its valuation relative to earnings has fallen to its lowest level since the AI investment boom began. That said, a separate development offered a partial offset: Beijing is reportedly planning to allow leading Chinese AI firms — including Alibaba and ByteDance — to purchase Nvidia's H200 chips, high-performance AI accelerators that had previously been subject to U.S. export restrictions. If confirmed, the policy shift would open a significant new revenue channel for Nvidia at a moment when its domestic competitive position is under pressure.

Broadcom (AVGO) was the chip sector's notable exception on the day. The company rose after Apple (AAPL) formalized a multi-year chip supply agreement valued at over $30 billion, running through 2031. The deal — the largest under Apple's American Manufacturing Program — includes an Apple investment to modernize one of Broadcom's manufacturing facilities. For Broadcom, the contract provides long-term revenue visibility that insulates it from near-term macro turbulence. For Apple, it deepens a vertical integration strategy built on custom silicon and domestic supply-chain anchoring. On a day when the chip sector was broadly selling off, Broadcom's gain stood out.

Under the Surface

The cross-asset picture told a coherent story. Crude oil's rally on supply-disruption fears was the clearest signal: the Middle East accounts for a substantial share of global oil output, and any escalation raises the risk of reduced flows through key shipping lanes. Energy stocks followed oil higher while the rest of the market fell — a textbook geopolitical rotation.

The VIX — the market's implied volatility gauge — was not specifically quantified in available reports, but the character of Wednesday's session was consistent with a fear-driven, low-liquidity selloff rather than orderly repositioning. Chip stocks and high-multiple technology names moved more than the headline index numbers suggested, reflecting concentrated selling in the sectors most exposed to risk-appetite swings.

In credit markets, Bank of America extended a $520 million credit facility to OpenAI, marking the bank's first direct lending relationship with the AI company. The timing — on a day of broad risk-off sentiment — underscores how separately the private AI financing market has been moving from public equity sentiment. Pre-IPO credit lines of this scale are standard positioning moves for banks seeking a role in what could be one of the most closely watched technology listings in the coming years.

Thursday's Setup

The single most important variable heading into Thursday is the trajectory of U.S.-Iran relations overnight. Any formal military escalation or, conversely, a signal of de-escalation would move oil prices and risk assets sharply at the open. Energy stocks and crude futures are the most direct expressions of that trade.

For chip investors, the Nvidia H200-China development warrants close attention. An official confirmation from Beijing would represent a meaningful positive catalyst for NVDA at a time when the stock is testing multi-month valuation lows. Absent that confirmation, the sector remains exposed to further geopolitical-driven selling.

The Apple-Broadcom deal is largely priced in, but it sets a constructive tone for AVGO heading into earnings season. ExxonMobil's updated profit guidance similarly positions XOM well for its formal second-quarter results, which have not yet been reported.

The broader question for Thursday is whether Wednesday's selloff was a one-session repricing or the start of a sustained geopolitical risk premium in equities. Oil's direction at the Asian open will be the first answer.
