TCS Surpasses Accenture to Become World's Most Valuable IT Services Company

A sharp 19% fall in Accenture's shares, wiping out nearly $18 billion in market value, has allowed Tata Consultancy Services (TCS) to become the world's most valuable IT services company as of June 18, 2026, according to Bloomberg data.  

Despite a challenging year for Indian IT stocks, TCS now holds a market valuation of $84.6 billion. 

TCS Surpasses Accenture in Market Value 

Following a historic selloff in Accenture shares, TCS has achieved a market capitalisation of $84.6 billion, surpassing Accenture's $77.6 billion.  

This shift marks the first time since February 2021 that TCS dethrones Accenture as the leader in global IT services valuation. Accenture's decline is attributed to a weaker-than-expected Q4 revenue guidance and reduced full-year growth expectations. 

Accenture's Market Cap Falls 

Accenture's market cap, which peaked at $263 billion in December 2021, has significantly diminished.  

The company's new bookings declined by 2% for the quarter ending May 31, 2026. Concerns about demand visibility have intensified, impacting the broader technology services sector globally. 

Implications for the IT Sector Stocks 

Share price declines have affected other IT companies such as IBM, Infosys, and Wipro. IBM's market value fell by about 7%, equating to a $16 billion reduction, while US-listed shares of Infosys declined by 6%.  

European firms like Capgemini and Sopra Steria have also experienced downward market trends.
