EY global revenue reaches $57bn on strong AI demand

EY has reported that its global revenue reached $57bn, equivalent to £43bn, representing a near five per cent increase over the previous financial year. The firm attributed this growth primarily to a significant surge in demand for artificial intelligence services, which saw sales rise by nearly 50 per cent during the period. This performance positions the accounting giant as a key beneficiary of the current technological shift within the professional services sector.

The strategy division, EY-Parthenon, led the growth across all service lines with a seven per cent increase. Tax services followed with a six per cent rise, while consulting grew by over four per cent and assurance by three per cent. To support these developments, the firm invested $448m in training and development during 2026, with a specific focus on AI capabilities. Janet Truncale, EY global chair and chief executive, stated that the results demonstrate the strength of combining EY teams with alliance partners to accelerate value creation and turn disruption into sustained growth.

The announcement comes amid broader industry changes, including a recent incident where EY withdrew a study on loyalty rewards programmes after it was found to contain AI hallucinations and fake footnotes. Competitor Deloitte recently reported global revenue of $74.5bn, despite a decline in its technology division. In the UK, PwC saw revenue grow to £4.365bn, while Deloitte UK reported a two per cent increase to £5.81bn for the year ended 31 May 2026.
