AI Just Wiped $1 Trillion from Software Stocks -- And Markets Are Picking Sides

What Happened
Anthropic released a new suite of AI agent tools this week for its Claude Cowork platform -- tools designed to handle complex professional workflows across legal, sales, marketing, and data analysis. The market reaction was immediate and brutal.

The S&P 500 Software & Services Index dropped over 4% on Thursday alone, extending its losing streak to eight straight sessions. The index is now down roughly 20% year-to-date. A software ETF tracking traditional SaaS companies has plunged over 24% in 2026. In a single Tuesday session, $285 billion was wiped from stocks across software, financial services, and asset management sectors.

Who Got Hit Hardest
Thomson Reuters, Salesforce, and LegalZoom were among the biggest casualties in U.S. trading. The selloff spread globally -- India's Tata Consultancy Services and Infosys got dragged down with them. Any company whose core product involves organizing, analyzing, or automating professional workflows is suddenly in the crosshairs.

The Bull/Bear Debate
JPMorgan's Mark Murphy called the panic an "illogical leap" -- the idea that a single LLM plug-in could replace every layer of mission-critical enterprise software. He's got a point. Enterprise software isn't just features -- it's compliance, integrations, data security, and institutional inertia.

But the bears aren't wrong to be worried either. When investors see AI agents handling complex legal research, CRM workflows, and financial analysis in real-time, the existential questions about SaaS valuations become very real. The market is repricing the entire software stack.

What Traders Should Watch

• Software sector (IGV ETF) is technically oversold after an 8-session slide -- watch for a dead cat bounce early next week
• AI infrastructure plays (NVDA, AVGO, MRVL) could catch a bid as money rotates FROM software consumers TO AI enablers
• VIX surged above 20 this week -- elevated vol means wider spreads and faster moves. Size down accordingly
• The Feb 11 NFP and Feb 13 CPI reports could either stabilize or accelerate the selling depending on readings

The real question for traders: is this the beginning of a structural repricing of the entire software industry, or a fear-driven overreaction that creates one of the best buying opportunities of 2026?
