Software companies watched their valuations collapse as the very technology they championed turned against them. A senior financial analyst at Nexymus examines how Anthropic’s automation tools triggered the worst sector selloff since 2008.
The S&P 500 software and services index fell 4% on Tuesday. This marked the sixth straight session of losses. The total market value wiped out reached $830 billion since January 28.
ServiceNow crashed 7% in single-day trading. The company’s year-to-date losses now stand at 28%. Salesforce dropped 7%, bringing 2026 declines to 26%.
Intuit plummeted 11% during Tuesday’s session. The TurboTax parent now trades down 34% for the year. European markets mirrored the carnage with equal intensity.
The Anthropic Catalyst
Anthropic released new Claude Cowork plugins on Friday. The automation tools target legal work, sales processes, and data analysis. This demonstrated AI’s aggressive push into enterprise software territory.
Thomson Reuters suffered a 16% collapse due to disruption fears. The legal data provider faced existential questions about future relevance. LegalZoom, Experian, and London Stock Exchange Group all absorbed heavy losses.
The panic spread beyond legal services quickly. Advertising agencies tumbled as AI threatened creative work. France’s Publicis fell 4.1% while Britain’s WPP lost 3.3%.

Europe Joins The Selloff
The Stoxx Europe Software index shed over 5% Tuesday. British analytics firm RELX plunged more than 14%. French IT giant Capgemini dropped 9.2% by market close.
Wednesday brought no relief for European software names. The sector index declined another 1.9% in morning trading. TomTom led losses with a 12.5% drop.
SAP, Europe’s largest software company, fell nearly 4%. Trustpilot declined more than 7% during the session. German management software developer Atoss dropped 6.4%.
Private Credit Gets Hit
Alternative asset managers with software exposure tumbled dramatically. Blue Owl Capital crashed 9.8% on Tuesday. Ares Management dropped 10.2% while KKR fell 9.7%.
These firms maintain heavy software company exposure in lending portfolios. Apollo cut its software allocation almost in half during 2025. The position started around 20% at the beginning.
Private equity firms hired consultants to assess portfolio vulnerability. Arcmont Asset Management and Hayfin Capital Management both brought in outside advisors. The moves signal deep concerns about software sector stability.
Why Investors Panicked
JPMorgan analyst Toby Ogg described the situation bluntly. Software companies face “sentencing before trial” right now. Investors worry about growth assumptions extending beyond standard three-year forecasts.
AI startups need enterprise revenue to justify steep valuations. Their strategy mirrors Amazon’s historical approach of winning niches first. OpenAI and Anthropic push aggressively into lucrative enterprise markets.
The iShares Expanded Tech-Software ETF dropped over 14% in six sessions. January delivered a 15% decline already. Bloomberg Intelligence called sector sentiment “radioactive” and the worst ever.
The Bull Case Emerges
Some investment professionals view the carnage as an opportunity. Sycomore Sustainable Tech fund bought Microsoft shares during the downturn. The European fund beat 99% of peers over three years.
Microsoft trades below 23 times estimated earnings currently. This represents the cheapest valuation in roughly three years. The stock’s 14-day relative strength index hit oversold territory.
Just 67% of S&P 500 software companies beat revenue expectations this quarter. However, 100% exceeded earnings estimates according to Bloomberg data. This suggests margins remain resilient despite growth concerns.

Earnings Season Becomes Judgment Day
Just 67% of S&P 500 software companies beat revenue expectations this quarter. This compares with 83% for the overall tech sector. The miss rate signals genuine business deterioration across software categories.
However, 100% of software firms exceeded earnings estimates during the period. Profitability remained intact despite topline pressures from competition. Margin resilience provides some comfort to long-term holders.
Microsoft reported solid earnings last week despite the sector turmoil. The stock tumbled 10% on Thursday after the results anyway. Investors focused on slowing cloud sales growth rather than absolute numbers.
Historical Precedent Offers Hope
Software disruption fears have materialized many times before. Mobile technology once threatened Microsoft’s desktop dominance completely. Everyone assumed smartphones would replace personal computers entirely.
Microsoft’s stock appreciated 789% over the following decade. The company adapted successfully and expanded into cloud services. Software skepticism “happens a lot,” according to Bloomberg Intelligence analysts.
Ben Barringer from Quilter Cheviot offered a measured perspective. “We are not yet at the point where AI agents will destroy software companies,” he stated. Security concerns, data ownership issues, and implementation challenges provide defensive moats.
What The Future Holds
Near-term volatility will persist as markets digest AI implications. Companies must demonstrate they’re adapting rather than dying. Concrete examples of successful integration become essential for restoring confidence.
Software earnings over the coming quarters will prove decisive. Management teams need to show AI represents opportunity, not extinction. Generic promises won’t satisfy investors demanding proof of relevance.
The $830 billion destruction represents either massive overreaction or prescient repositioning. Barringer noted that during volatility, “people often shoot first and ask questions later.” Further turbulence seems inevitable before resolution emerges.
