In some ways, last week was like a mirror image of the week that preceded it. Whereas stocks began the earlier week strongly before giving up most (but not all) of their gains on Friday, last week began with a minor selloff before strengthening into Friday’s close. With this strengthening, the S&P 500 continued its weekly win streak, which now stands at eight – the longest since December 2023.
It’s a week that saw some key earnings reports, most notably from Nvidia. By any usual measure, Nvidia’s results would be viewed superlatively: the chip giant reported revenues rising 85% YoY to hit a record $81.6 billion, with earnings beating and gross margins at 74.9%. But this is Nvidia, a company from which investors habitually see big numbers. As Fundstrat Head of Research Tom Lee observed, “the stock barely reacted to the report. This arguably reflects markets expecting good results,” he suggested, but he viewed them as nevertheless “astounding” and “impressive.”
On Friday, Kevin Warsh formally took the helm of the Federal Reserve. Lee sees a fundamental policy decision awaiting him and the central bank: which matters more to structural inflation, oil prices or AI? Oil prices slid last week but remain elevated, with WTI crude at around $97 as of Friday afternoon. This could push up inflation – and if the effect persists, it could thus increase the Fed’s inclination to hike rates in the future. This possibility was already foreshadowed in the minutes from the April 29 Federal Open Market Committee (FOMC) meeting.
On the other hand, though AI might have a short-term inflationary effect due to its consumption of energy and its effect on chip prices, its likely downward impact on employment and worker wages will arguably have a deflationary effect, thus giving the Fed a dovish inclination.
The developing interplay between these two factors will be important to monitor. “Timing is key and which of these forces becomes the primary narrative in 2026 is key,” in Lee’s view.

Chart of the Week

SpaceX formally announced its IPO plans last week, and it is slated to be the largest U.S. IPO ever, with the company’s pre-money valuation representing 2.7% or more of the total U.S. equity market. Investors also have high expectations for the IPOs of OpenAI and Anthropic, expected for later this year. These large public debuts raise questions about how they will affect the broader market overall. As Fundstrat Head of Tom Lee explained, “an IPO represents a sizable increase in equity supply,” with the impact generally coming about six to 12 months later after lockup expirations for shares held by early investors take place and the shares become tradeable. Our Chart of the Week shows how this manifested after the 10 largest U.S. IPOs. to date, and it is worth keeping in mind further down the road.
