Nifty IT slides 4% as AI fears hit TCS, Infosys

What drove the sudden selling in IT

Indian IT stocks fell sharply as investors moved to book profits after a two-day rally that had been supported by AI optimism and expectations of better software spending. The reversal was also linked to weak cues from US-listed American Depository Receipts (ADRs) of Indian IT companies and a decline in global tech sentiment. At the centre of the selloff was renewed debate over how quickly AI could compress pricing, reduce headcount-led billing, and weaken traditional outsourcing economics. The market reaction was not limited to one stock, but the pressure intensified after Tata Consultancy Services (TCS) earnings and broader global developments.

Profit booking after a two-day IT rally

The immediate trigger cited for the Wednesday decline was profit booking after what was described as a strong rally. After leading the market recovery over the previous two sessions, IT stocks saw investors lock in gains. The move was characterised as a reversal from an “overextended relief rally”, with selling led by TCS.

One market view in the provided text flagged TCS as the “weakest link”, citing margin pressure and weak growth visibility. It also noted that TCS was down nearly 23% in 2026, underscoring how quickly sentiment has shifted from AI optimism to concerns about growth durability.

TCS Q4 reaction spills across the sector

The rout was also tied to investor reaction to TCS Q4 earnings and revenue commentary. In a separate session described in the text, the Nifty IT index was reported down 2.68% as investors liquidated tech positions following disappointing revenue data from TCS.

TCS fell 3.28% to trade at Rs 2,503 in heavy volume in that move. Even though the company reported a 29% jump in quarterly net profit, investors focused on the statement that TCS recorded its first-ever full-year revenue decline in dollar terms since its stock market listing. The company also pointed to record mega-deals worth USD 12 billion, but the market response suggested investors were more concerned about near-term discretionary spending conditions, including weakness referenced in North American financial services.

Multi-session pressure: new lows and market-cap threshold breach

The selling pressure was described as persisting into a second straight session, with TCS hitting a five-and-a-half-year low of Rs 2,585 in one of the moves referenced. Elsewhere in the text, TCS was also said to have breached the psychologically important Rs 10 lakh crore market capitalisation level, while hitting a fresh 52-week low of Rs 2,776 on the BSE as the share price fell 4.5%.

The broader sectoral move was described as broad-based, with the Nifty IT index plunging nearly 4% at one point. Heavyweights such as Infosys, HCLTech, Mphasis and Wipro were reported down 4-5% each, dragging the sector lower.

Global tech cues: Nasdaq fall and weak IT ADRs

Global risk-off cues added to the pressure. The text cited a 2.03% drop in the Nasdaq Composite overnight and persistent weakness in ADRs of Indian IT majors Infosys and Wipro. It also pointed to a sharp fall in global tech stocks such as Adobe, Salesforce, Cognizant and Accenture.

The combination of global tech weakness and sector-specific fear around AI adoption created a challenging set-up for Indian IT stocks, which are sensitive to changes in US enterprise spending and global technology valuations.

The AI trigger: Anthropic’s legal automation push

A key narrative driver was a product announcement from US-based AI startup Anthropic, the maker of the Claude chatbot. The company unveiled a tool tailored for corporate legal teams that can automate tasks including contract reviews, non-disclosure agreement triage, compliance workflows, legal brief preparation and standardised responses. The text also referenced “Claude Cowork”, described as a “digital coworker” with 11 enterprise automation plug-ins designed for corporate legal teams.

This announcement fed into investor concerns that AI could reshape parts of the software and IT services value chain. Functions previously viewed as relatively insulated such as legal services, data analytics and customer support were cited as becoming more vulnerable to automation. The fear highlighted was that large-scale automation could pressure profitability and alter competitive positioning for IT services firms.

Macro backdrop: US jobs data and rate-cut expectations

The selloff was compounded by stronger-than-expected US jobs data, which weakened expectations of near-term rate cuts by the Federal Reserve. The text cited the addition of 1,30,000 jobs and unemployment falling to 4.3%. Growth-sensitive technology stocks typically react to changes in rate expectations because discount rates influence valuations, particularly for longer-duration earnings.

Market impact: index fall and market value erosion

The sector’s decline was linked to broader benchmark weakness as technology is described as the second-largest profit pool of India Inc. The text cited a combined market value fall of Rs 1.3 lakh crore for IT companies in one instance, with the combined market cap reported at Rs 27.6 lakh crore after the drop. Separately, it also stated that about Rs 1.9 lakh crore in market capitalisation was wiped out in one of the steep one-day declines referenced.

Key datapoints mentioned

Why the selloff matters for Indian IT investors

The key question raised by the move is whether AI adoption becomes a headwind for deal wins and topline growth if automation reduces demand for traditional entry-level services work. The text also pointed to pressure on the headcount-based outsourcing model as advanced AI tools cut delivery timelines through automated tasks.

International brokerage Jefferies was cited describing the shift in sentiment as a “SaaSpocalypse”, reflecting a reversal from “AI helps these companies” to “AI replaces these companies”. In this context, the decline was framed not as a routine dip, but as a structural re-rating risk driven by global AI developments, macro signals, and concerns about revenue deflation in IT services.

Conclusion

Indian IT stocks fell as profit booking collided with weak global tech cues, a negative market reaction to TCS revenue commentary, and intensified concerns about AI-led disruption following Anthropic’s enterprise automation announcement. With US jobs data also reducing rate-cut expectations, investors shifted to a more cautious view on growth-sensitive technology names. The next market focus remains on how IT companies communicate demand trends, deal conversions, and delivery model changes as AI capabilities expand.
