Anthropic AI Sparks Global Tech Sell-Off, Hits Indian IT Hard

A Global Wake-Up Call for Tech Investors

In early February 2026, global technology markets received a severe jolt. The release of a new suite of advanced AI tools by the startup Anthropic triggered a widespread panic, leading to a massive sell-off across US software companies, global IT services firms, and even Big Tech leaders. The Nasdaq 100 fell 1.55% in a single session, while software-focused indices dropped even further. The event erased over $180 billion in market capitalization globally, with Indian equities alone losing an estimated ₹2 lakh crore. This was not a routine market correction; it was a reaction to a fundamental fear that AI is evolving from a productivity tool into a direct replacement for core components of the software and services industry.

The Catalyst: Anthropic's Disruptive AI Tools

The market turmoil was ignited by Anthropic's announcement of new features and plugins for its AI models, specifically Claude Code and Claude Cowork. These tools were designed to autonomously execute complex white-collar workflows. For instance, a new feature for Claude Code enabled the scanning of software for security vulnerabilities, a task that has long been a staple for cybersecurity firms. Similarly, new plugins for Claude Cowork automated functions in sales, legal research, contract drafting, and financial analytics. This positioned Anthropic's AI in direct competition with established enterprise software from firms like Salesforce, Intuit, and major IT service providers.

Panic on Wall Street

The reaction on Wall Street was swift and brutal. The announcement on February 20 about Claude Code's security feature sent shockwaves through the cybersecurity sector. IBM became the most prominent casualty, with its stock plummeting 13% in a single day, marking its worst loss in over 26 years. The broader iShares Expanded Tech-Software Sector ETF, a key barometer for the industry, fell 4% on the news, contributing to a year-to-date decline of over 26%. The sell-off was not confined to a single day. In the days following Anthropic's earlier plugin releases, the same ETF had already dropped 11%, signaling deep investor anxiety.

Market Reaction Snapshot

The sell-off was broad, hitting companies across the technology spectrum. The fear was that AI could significantly erode the market for many software-as-a-service (SaaS) companies whose business models rely on recurring license fees for specific workflows.

The Shockwave Reaches Dalal Street

The panic that began on Wall Street quickly spread to global markets, hitting Indian IT stocks particularly hard. As US markets closed, the American Depositary Receipts (ADRs) of Infosys and Wipro fell sharply. By the time Indian markets opened, a wave of selling was already underway. India's Nifty IT index plunged 5.8%, its worst single-session performance in nearly six years. Major IT exporters felt the heat, with Tata Consultancy Services (TCS) falling 7% and Infosys dropping 7.3%. Other giants like HCLTech and Wipro also saw significant declines. The sell-off was especially jarring as it wiped out gains made just a day earlier following positive news about a trade deal with the United States, highlighting how AI disruption fears had overshadowed all other market catalysts.

Why the Reaction Was So Severe

Several factors contributed to the intensity of the market's reaction. Firstly, Indian IT stocks were already trading at high valuations amid concerns over slow deal ramp-ups and weak discretionary spending from clients in the US and Europe. The market was already nervous, making it susceptible to a shock. Secondly, and more fundamentally, this event marked a shift in perception. For the first time, markets treated AI not as a supportive technology but as a zero-sum force capable of displacing incumbents. The narrative quickly became about AI replacing software and service jobs, which triggered index-driven selling that pulled down even stocks with minimal direct exposure. Analysts noted that the sheer pace of AI innovation surprised investors, who believed such disruption was years away, not an immediate reality.

Broader Industry Impact

The impact was felt far beyond traditional IT services. The legal tech sector was hit hard, with Thomson Reuters suffering a record 16% single-day plunge on fears that its core legal division was vulnerable. Legal software providers like LegalZoom and CS Disco plummeted 20% and 12%, respectively. Data analytics businesses were also affected, with the London Stock Exchange Group dropping 13%. This demonstrated that any industry reliant on structured data processing, analysis, and professional services is now seen as potentially vulnerable to advanced AI automation.

What Lies Ahead for the Tech Sector

The market volatility is expected to continue. Every new AI announcement from major players like Anthropic will likely be scrutinized for its disruptive potential, testing investor nerves. The sell-off serves as a critical reminder that sentiment around technology is fragile. For Indian IT companies, the challenge is now to prove that AI is an opportunity to enhance their service offerings and strengthen their global position, rather than an existential threat. The coming months will be crucial as companies articulate their strategies for adapting to a landscape being reshaped by artificial intelligence in real time.
