Software Rallies, Chips Sink 5.9% as AI Lab CEOs Call for Slowdown Ahead of Fed
ServiceNow, Adobe and Workday rose 4% to 7.4% Monday while the PHLX chip index fell 5.9% — repricing the SaaS stack small teams depend on to win customers.
ServiceNow, Adobe, and Workday rallied between 4% and 7.4% Monday while the PHLX chip index fell 5.9%, a rotation that quietly repriced the software layer most small businesses actually use to run sales and marketing. The trigger: Anthropic’s Dario Amodei, OpenAI’s Sam Altman, and Elon Musk of xAI publicly floated a slower cadence on frontier-model capability gains, and the market treated it as a durability signal for enterprise SaaS.
The tape’s split-screen is the story. Nvidia fell 3.4%, Micron dropped more than 5%, Broadcom and AMD each shed over 4%, and the picks-and-shovels layer got dumped harder: Hewlett Packard Enterprise slid roughly 11%, Dell 6%, Oracle 4%, CoreWeave about 7%, SK Hynix 7% in U.S. trading, Vertiv about 8%. Bernstein flagged CoreWeave as one of the most exposed AI names. Meanwhile Palo Alto Networks and CrowdStrike each jumped more than 13%, with Okta, Zscaler, Qualys, SentinelOne and Netskope posting double-digit gains. The PHLX’s 2026 gain was cut to 57%.
The index-level move was mild. The S&P 500 closed down 0.48% at 7,619.94, the Nasdaq off 0.56% at 26,186.41, with tech the worst sector at –1.68%. Volume ran 15.3 billion shares against a 20-session average of 14.8 billion. Under the hood, capital rotated from compute buildout into recurring software revenue.
That rotation lands 48 hours before a Fed meeting where a 25-basis-point hike is priced at 90%, with the 10-year briefly topping 5% for the first time since 2023 and Brent settling 1% higher at $105.68. Which is the point small teams should register: the CRM, marketing, and security tools they subscribe to just got revalued as durable infrastructure, and durable infrastructure doesn’t discount. Vendors whose stocks rip 7% on a Monday have no reason to extend a trial on Tuesday.
The framing echoes the 2022 SaaS reset in reverse. Then, rising rates crushed software multiples on duration risk. Now, an AI-capability plateau is being read as a moat for incumbents that already own the workflow. For a five-person shop paying seat fees on a business credit line about to reprice, the audit isn’t whether the stack is fashionable. It’s whether each subscription produced pipeline last quarter.
