Market volatility has intensified in the Indian IT sector as the Nifty IT index fell nearly 5% in a single session on February 13, 2026. This decline marks the worst weekly performance for the technology basket since March 2020. Total weekly losses for the index have reached 10.8%, dragging the year-to-date return to a negative 17.5%. Investors have wiped out over 4 lakh crore in market capitalization during this period. The sell-off is largely attributed to the "Anthropic Shock," following the launch of highly advanced AI automation tools that threaten the traditional labor-intensive outsourcing model. Large-cap heavyweights are bearing the brunt of the pressure. Infosys saw its share price tumble 6.3%, reaching its lowest point since April 2025. Tata Consultancy Services (TCS) dropped 4.9% to hit a fresh 52-week low. Other major players including HCL Tech and Wipro recorded declines between 3.5% and 4.7%. Despite the immediate panic, industry experts maintain a contrarian outlook. Analysts suggest that while AI may cause revenue deflation due to reduced manpower requirements, it will significantly boost profit margins. The sector is currently shifting from a manpower-based delivery system to an "asset-led" model. AI-centric engagements now account for approximately 74% of all new contracts signed by major firms over the last six quarters. Strategic pivots are visible across the Big Six. TCS has launched physical AI initiatives and sovereign cloud ecosystems, while Wipro is prioritizing agentic and embodied AI. Mid-cap and specialized firms like Persistent Systems and L&T Technology Services are increasingly viewed as high-growth AI infrastructure plays. India’s broader AI market is projected to reach 17 billion by 2027, supported by 70 billion in ongoing data center investments. Valuations for the Nifty IT index have moderated to a price-to-earnings ratio of 22.4, down roughly 25% from recent peaks. Institutional data shows that mutual funds have maintained strong positions, adding over 1 crore shares to several IT stocks in early 2026. The current correction is being framed by long-term investors as a transition phase rather than a sector collapse, as companies move from billable hours to high-impact, outcome-based revenue streams.
