Revenue Growth Decouples for Top Indian IT Firms Amid GenAI and GCC Shifts

India’s five largest IT services firms—

, , , , and —have seen revenue growth slow to 1–2% since 2023, trailing their global clients’ 3–5% growth. This decoupling signals a structural shift in tech spending, driven by automation, AI adoption, and rising in-house tech capabilities among Fortune 500 and Global 2000 firms. - Revenue Growth Divergence from Global Clients Historically, Indian IT firms’ growth mirrored that of S&P 500 and Stoxx 600 companies. Since CY23, this correlation has weakened. While global tech revenue rose 15%, India’s top IT firms grew just ~1%, reflecting a shift in client priorities and delivery models. GenAI adoption has enabled clients to optimize costs and reduce reliance on external IT services. Projects now require fewer billed personnel, and pricing is increasingly outcome-based. This deflationary impact is hurting net revenue growth for Indian IT firms. Clients are investing in Global Capacity Centres (GCCs) and product-centric tech firms, diverting spend away from traditional outsourcing. This trend is especially pronounced among tech-heavy clients like Microsoft and Apple, which contribute 8–16% of revenue for India’s Big Five. The post-Covid surge in digital transformation has faded. Discretionary IT spending is delayed amid macro uncertainty, and cost reduction remains a key client focus. Nomura notes that tier-1 IT firms are growing slower than G2000 peers, with sub-5% quarterly growth. The Big Five account for 28% of India’s tech sector. Their slowdown could cascade to mid-tier firms. Analysts remain cautious, citing an “unconvincing revenue trajectory” and structural headwinds. Recovery may hinge on GenAI monetization, GCC partnerships, and diversified service models.
