NEW YORK, Feb 3, 2026, 16:31 (ET) — Trading in after-hours
Microsoft shares fell 2.9% to $411.21 in after-hours trading Tuesday, following a drop during the main session. The stock started the day at $422.00 and fluctuated between $426.50 and $408.62, with roughly 59.9 million shares traded.
The decline followed a broader selloff in software and data-analytics stocks, sparked by new automation tools from Anthropic that reignited the “AI disruption” debate. “Sometimes the market just shoots first and asks questions later,” Mike Archibald of AGF Investments remarked. Jonathan McMullan at Schroders added that investors are “aggressively repricing” as the long-held valuation premium for predictability begins to erode. Reuters
This is crucial now as traders bet on one straightforward thesis: AI investment will boost the largest platforms—and quickly. Once new tools emerge that seem to handle tasks once billed by software, the narrative falters, and the stock ticker reacts accordingly.
Microsoft has faced increased scrutiny since its recent earnings report, which highlighted record AI investments alongside a slowdown in cloud-computing growth. This combination unsettled investors wary of short-term returns.
Piper Sandler stuck with its Overweight rating on Microsoft, signaling expectations that the stock will outperform. The firm held firm on a $600 price target, naming Microsoft a top pick despite cautioning that “seat-compression” might limit valuation multiples in the software sector. TipRanks
Seat compression refers to the risk that customers purchase fewer software “seats”—paid user licenses—as AI tools increase worker productivity. This presents a new challenge for a market accustomed to consistent subscription growth.
The danger is Tuesday’s selloff could linger: investors continue viewing AI as a margin risk for segments of the software stack, even as large firms pour cash into data centers to keep pace. In this environment, any relief rallies may prove fleeting.
The next big test comes with a packed earnings slate from megacap tech, as investors hunt for signs on cloud demand, AI spending, and competitive pressures. “We’re seeing a lot of software companies across the spectrum get hit,” noted Art Hogan of B. Riley Wealth. John Campbell at Allspring Global Investments added that expectations for AI “are really high.” All eyes will be on Alphabet on Wednesday and Amazon on Thursday for insights. Reuters
