Microsoft Corporation (NASDAQ:MSFT) fell 2.6% on Tuesday as technology names focused on software experienced widespread weakness.
The iShares Expanded Tech-Software Sector ETF slipped about 4% on the day, with two of its largest holdings, Palantir Technologies and Salesforce, falling roughly 5% each. Market participants attributed the sell-off to fresh developments in AI automation that investors fear could alter established software business dynamics.
Anthropic on Tuesday announced an expansion of its Claude AI assistant's capabilities to allow it to control computers to complete tasks. The new feature permits the assistant to open applications, navigate web browsers, and populate spreadsheets. It is accessible in Claude Cowork and Claude Code for macOS users and is designed to let the AI operate directly on a user’s screen in situations where an app connector does not exist.
The functionality also lets users assign tasks from mobile devices and later return to completed work on their desktop computers. Users may schedule recurring jobs such as scanning email each morning or producing weekly reports. Anthropic stated the capability is available to Pro and Max subscribers.
Separately, a report said Amazon Web Services is developing AI agents intended to automate functions across sales, business development, and other teams where the company recently reduced headcount by several hundred employees. According to that reporting, AWS has been creating an AI agent to assist sales personnel in answering technical questions, taking on work that was previously handled by thousands of technical specialists in areas such as cybersecurity and server networking.
An AWS spokesperson confirmed the firm is working on an agent that "aggregates specialist knowledge from across AWS," saying the technology is intended to allow employees to "focus on the most complex, high-value customer challenges."
These announcements underline mounting concerns about the potential for AI automation to reshape revenue and labor models within traditional software and services businesses. Market reaction on Tuesday reflected those concerns, with notable pressure across software equities.
