The software sector experienced a significant downturn on Tuesday, with multiple negative factors converging to reignite market concerns about artificial intelligence disrupting traditional software business models.
On March 24, a report by The Information indicated that Amazon Web Services (AWS), the cloud computing division of Amazon.com, is developing AI agents designed to automate functions in roles such as sales and business development. These are precisely the areas affected by recent large-scale layoffs at Amazon.
Simultaneously, AI startup Anthropic released an upgraded version of its Claude model on Monday evening. The new version can take control of a user's computer to perform office tasks such as browsing the web and filling out spreadsheets, further intensifying market fears about AI replacing human labor.
Software stocks collectively plummeted on Tuesday. The iShares Tech-Software Sector ETF fell over 4% for the day, marking its largest single-day decline in nearly a month. Its year-to-date losses widened to 23%, potentially setting it up for its worst quarterly performance since 2008. In contrast, the Philadelphia Semiconductor Index rose 1.2%.
The forward price-to-earnings ratio for the tech-software sector has now fallen below that of the overall S&P 500. Some market participants stated bluntly that the software sector is experiencing massive capital destruction.
For investors, the window for a valuation recovery in the sector remains difficult to predict until the impact of AI on enterprise software subscription models evolves from narrative to actual financial performance.
The development of AI agents by AWS and the release of a desktop agent by Anthropic are directly targeting the automation of white-collar jobs.
According to The Information, citing people familiar with the matter, the AI agents being developed by AWS are capable of handling part of the workload of thousands of technical experts in areas like cybersecurity and server networks.
The report noted that these agents aim to automate functions previously performed by sales and business development personnel, roles that have already been impacted by recent waves of layoffs at Amazon.
This report has intensified market worries about the logic of "internal replacement" by AI. Tech giants are not only cutting human jobs but are also filling the corresponding functional gaps with their own AI tools. This trend poses a direct threat to traditional software subscription models, which are often priced based on the number of enterprise users.
In a separate development, Anthropic announced two significant updates to Claude on Monday evening.
The first is a new version of the Claude Cowork desktop agent, which features enhanced capabilities for controlling Mac systems and can be operated remotely via the Claude mobile app.
The second is a research report from the Anthropic Economic Index, indicating that the use cases for Claude tools are rapidly expanding from programming and development to office administration, finance, and management tasks.
The report also noted that experienced users with "AI fluency" consistently achieve better results compared to novices, leading to productivity and income disparities within the same job roles. This conclusion has been interpreted by the market as an early signal of AI replacing routine white-collar jobs.
It is important to note that the report highlighted that desktop agents are still in the early research stages and come with significant risks, including data leaks, accidental deletions, and new types of security vulnerabilities.
The sector's pressure stems from a combination of multiple factors, not a single cause.
Daniel O'Regan, an Equity Trading Executive at Mizuho, stated that Tuesday's weakness in software stocks resulted from the convergence of several smaller factors. Beyond the AWS agent development and the new Claude release, he listed the following points:
First, the 10-year U.S. Treasury yield rose to an 8-month high this week, putting pressure on high-valuation sectors.
Second, David George, a General Partner at Andreessen Horowitz, published an article stating that software companies have only two paths forward. They must either develop AI-native products to increase annual revenue growth by more than 10 percentage points within the next 12 to 18 months, or rebuild their operating margins (including stock-based compensation) to 40% or even above 50%.
Third, a research firm issued a negative report on global team collaboration software developer Atlassian, indicating that its partners' performance this quarter was slightly below plan and that growth is expected to slow in 2026. Atlassian's stock closed down over 8%.
Fourth, within the tech-software sector ETF, the stock price of Circle plunged sharply due to concerns surrounding stablecoin legislation, plummeting approximately 20% in a single day. Although its weight in the ETF is only 0.28%, Daniel O'Regan expressed the view that Circle, as a fintech company issuing stablecoins, fundamentally should not be included in the ETF.
