Chip Stocks Surge on Strong Earnings as Palantir and Other Software Names Slide Pre-Market
Nashnova编辑部
Strong chip and fiber-optic earnings on August 13, 2026 triggered a pre-market rotation out of software — Palantir fell 1.3%, Microsoft 0.7% — as investors repriced who wins and who gets disrupted across the AI stack.
Chip earnings beat — why did software stocks drop?
Chip and fiber-optic networking companies posted strong results, signaling that AI demand remains robust. Their shares rose pre-market.
Capital is finite: money rushing into chips drained out of software. Palantir fell 1.3%, Microsoft 0.7%; Salesforce, ServiceNow, and Workday all slid, ranking among the S&P 500's worst performers.
This means → every chip earnings beat reactivates a "compute beneficiary vs. compute-disrupted" funding seesaw.
Is the software sell-off just a fund rotation?
Not entirely. The deeper driver is the market's fear that AI will disrupt the software industry itself.
Vibe-coding — tools that turn natural-language prompts directly into working code — is advancing fast. The concern is that some existing software products could face obsolescence.
In plain terms = if AI can write the code, the long-term value of companies that sell coding tools comes into question. What's being compressed is not near-term earnings but the ceiling on long-run valuation.
Are software stocks stuck on the losing side?
Not at all. Over the past three months, Palantir rose 35% and Microsoft gained 24% — precisely during a stretch when investors worried chip valuations had run too high.
This reflects a two-way seesaw: when money flows out of chips, software becomes the shelter.
This means → the current sector rotation is not "chips always win, software always loses." Investors are repricing back and forth between the two asset classes — and every earnings season can flip the direction.
