EY, KPMG, and Deloitte Dominate India's Audit Landscape in FY26

The Indian corporate audit sector remains highly consolidated, with global giants maintaining a firm grip on the nation's listed entities. Recent data highlights a market where a handful of institutional players manage the vast majority of listed company audits, both by volume and by total market valuation.

EY, KPMG, and Deloitte Lead by Audit Volume

According to data compiled by Prime Infobase, the "Big Four" continue to dictate the scale of the audit market in FY26. EY Group maintained its leadership position, auditing 187 companies, a 3% increase from its FY25 count of 182. KPMG Group showed significant momentum with an 11% growth in volume, rising to 157 companies. Deloitte Group held the third spot with 131 companies, despite a slight dip from 137 in the previous fiscal year.

Other notable players in the top 10 list include GT Group (125 companies), BDO Group (97), and PWC Group (82). While the global giants dominate the top tier, CNK & Associates LLP emerged as a standout performer, recording the fastest growth among the top 10 with a 41% jump to audit 24 companies.

Financial Scale: Market Capitalisation Dominance

While volume measures reach, market capitalisation reveals the true financial influence of these firms. KPMG Group emerged as the leader in terms of the sheer value of the companies it oversees, auditing entities that constitute 15.67% (Rs 71,14,060 crore) of the total market capitalisation in the report. EY Group followed closely at 15.35% (Rs 69,73,130 crore), and Deloitte Group captured 13.94% (Rs 63,31,111 crore).

Combined, these three firms command nearly 45% of the total market capitalisation of the listed entities covered. The broader "Big Six" institutional groups hold a 61% collective share, while the global Big Four firms account for 51% of the entire market capitalisation, underscoring a massive concentration of financial oversight.

Market Fragmentation and Auditor Turnover

The data reveals a stark contrast between the top tier and the rest of the industry. While only 25 audit firms manage portfolios of 10 or more listed companies, a staggering 649 audit firms audited just a single listed company during FY26.

The report also highlights increasing volatility in auditor relationships. Mid-term cessations—including resignations and terminations—rose to 71 instances across 68 companies in FY26, up from 58 instances in FY25. Furthermore, year-on-year auditor changes were recorded across 323 companies. Looking ahead to FY27, the industry faces significant transition cycles, with 1,030 auditors across 997 companies scheduled to see their tenures expire, including 385 auditors completing a full 10-year term.

Key Takeaways

  • Concentrated Power: The Big Four firms command 51% of the total market capitalisation of audited listed entities, showing their massive influence over India's largest corporations.
  • Growth Trends: While EY leads in volume (187 companies), KPMG showed the strongest growth (11%), and CNK & Associates emerged as the fastest-growing firm in the top 10 (41%).
  • Industry Volatility: Auditor turnover is on the rise, with mid-term cessations increasing from 58 to 71 instances year-on-year.
