The Session

Friday closed a remarkable month for U.S. markets with a session that felt like a summary of everything 2026 has been about: artificial intelligence driving blowout corporate results, geopolitical diplomacy reshaping commodity prices, and the two forces reinforcing each other in ways that pushed broad indices to fresh record highs.

Dell Technologies (DELL) surged approximately 33% — its best single-day performance since returning to public markets in 2018 — after reporting a 757% year-over-year jump in AI server revenue in its fiscal Q1 2027 results. Management raised full-year revenue and earnings guidance, citing accelerating orders from hyperscalers, the large cloud infrastructure providers building out AI data centers at pace. Snowflake (SNOW) added a 36% gain of its own on a strong earnings beat and a new partnership with Amazon Web Services. The S&P 500, Nasdaq, and Dow all closed at all-time highs.

At the same time, crude oil was completing one of its worst monthly performances in recent memory, on track for a roughly 19% decline in May as traders priced in the prospect of a U.S.-Iran nuclear agreement that could return significant Iranian supply to global markets.

Winners and Losers

Dell's move was the session's single most dramatic story. A 757% revenue surge in AI servers is not a rounding error — it reflects the scale of capital spending flowing through to the companies supplying the physical layer of the AI buildout. Management's guidance raise reinforced the message: order books remain full. Super Micro Computer, a rival server maker, climbed around 16% in sympathy, confirming that the market read Dell's results as a sector-wide signal rather than a company-specific win.

Snowflake's 36% gain was nearly as striking. The cloud data platform had faced skepticism in prior quarters about whether it could credibly monetize AI demand. Friday's results, paired with the AWS partnership announcement, addressed enough of those doubts to trigger a sharp re-rating. Together, Dell and Snowflake illustrated a widening divide within technology: companies able to show AI driving actual reported revenue are being rewarded at a different magnitude than those still telling a forward-looking story.

Adobe (ADBE) sat firmly on the other side of that divide. Management acknowledged during its earnings call that Firefly, the company's own generative AI image tool, is cannibalizing revenue from its stock photo marketplace. The admission is unusual — a major technology company publicly conceding that its own product is eroding an existing revenue stream. Shares fell in response. The episode raises a question that will follow Adobe into the next several quarters: can Firefly's growth offset the stock photo revenue it displaces, and does the timeline work in shareholders' favor?

Pfizer (PFE) added a deal-making dimension to the session with a $10.5 billion co-development agreement with China's Innovent Biologics covering 12 early-stage oncology programs. The $650 million upfront payment reflects Pfizer's confidence in the pipeline; the remainder is contingent on development and commercial milestones. Innovent shares surged on the news. For Pfizer, the deal extends a deliberate pivot toward oncology as the company rebuilds its pipeline following the wind-down of COVID-era revenues.

In private markets, Apollo Global Management and Blackstone arranged a $36 billion debt financing deal to acquire Google tensor processing units — specialized AI chips — which will be leased to AI startup Anthropic. The structure, a sale-leaseback arrangement, allows Anthropic to access computing capacity without carrying the hardware on its own balance sheet. At $36 billion, the deal ranks among the largest single financing arrangements in the private credit market and signals that alternative asset managers now view AI compute infrastructure as a durable, leasable asset class.

Under the Surface

The oil story deserves more attention than it typically receives on a day dominated by earnings headlines. A roughly 19% monthly decline in crude is a macro event with real transmission effects. Lower energy costs reduce input inflation for businesses and ease pressure on household budgets — both dynamics that reduce the urgency for the Federal Reserve to tighten monetary policy further. That chain of logic partly explains why equity valuations held up and extended even as some analysts flagged lingering inflation concerns.

UBS's Chief Investment Office maintained a constructive year-end view on U.S. equities, with a target of 7,900 for the S&P 500, while acknowledging that inflation risks and the possibility of Fed rate action have not fully disappeared. The oil decline gives the Fed more room to hold, but it is not a guarantee — particularly if diplomatic progress on Iran stalls or reverses.

Energy-sector equities and commodity-linked currencies underperformed on the day, the natural counterpart to the crude selloff. For producers and energy-focused funds, a 19% monthly drop is not a rounding error either.

Market internals broadly supported the rally's legitimacy. The breadth of gains — spanning hardware, cloud software, healthcare dealmaking, and macro relief — made this a session where the advance was not narrowly concentrated in a handful of names.

The Setup Heading Into June

The dominant variable carrying into next week is the U.S.-Iran nuclear framework. A formal announcement could push crude lower still, extending the disinflationary tailwind for equities. A breakdown in talks — or any escalation of regional military tensions — could reverse the oil move sharply and complicate the benign macro narrative that supported Friday's record close.

On the earnings front, the AI infrastructure trade has now been validated at multiple points in the supply chain: chips, servers, cloud data platforms. The question heading into summer is whether enterprise software companies beyond Snowflake can show similar AI revenue conversion, or whether the gains remain concentrated in hardware and infrastructure.

Fed speakers and June economic data, including manufacturing and services PMI readings, will be watched for any signal that the rate path is shifting. For now, markets closed May with the wind at their backs — record equities, falling energy costs, and a wave of AI earnings that moved from narrative to numbers.
