TCS Regains Global Leadership as Market Turmoil Reshapes IT Services Valuations

Tata Consultancy Services ($TCS) has once again become the world's most valuable IT services company, surpassing Accenture for the first time since February 2021 following a sharp selloff in global technology stocks. Despite a nearly 19% decline in its own share price this year, which erased around $18 billion in market value, TCS ended with a market capitalisation of $84.6 billion, about $7 billion ahead of Accenture's $77.6 billion. Accenture, whose valuation once peaked at $263 billion in December 2021, faced pressure after issuing weaker-than-expected fourth-quarter revenue guidance, lowering the upper end of its FY26 organic constant-currency revenue growth forecast by 100 basis points to 3%-4%, and reporting a 2% decline in new bookings for the quarter ended May 31. As a result, Accenture's market value has fallen by more than 50% since the start of the year, while TCS has seen a comparatively smaller decline of around 30%. Among other major players, IBM remains the largest IT services company with a market value of approximately $231 billion, although its shares fell about 7%, wiping out nearly $16 billion in a single session. Infosys ranks fourth globally with a market capitalisation of $48.5 billion, followed by Fujitsu at $36.3 billion. The weakness in Accenture's outlook also triggered a broader sector-wide selloff, with IBM and Cognizant declining nearly 7% each, Infosys ADRs falling 6%, Wipro ADRs dropping 7.3%, Capgemini losing 11%, Sopra Steria falling 6.8%, Globant declining 13%, EPAM Systems dropping 11%, and CGI losing over 9%. The recent developments indicate that investors are closely reassessing the impact of artificial intelligence, discretionary spending trends and demand visibility, which could continue to influence valuations and sentiment across the global IT services industry.
