Consulting firms are emerging as significant beneficiaries of the AI boom, with companies like BCG, McKinsey, KPMG, IBM, and Accenture experiencing substantial revenue growth from AI-related services. BCG now derives 20% of its revenue from AI work, a notable increase from 0% two years ago. McKinsey expects roughly 40% of its business to be AI-related this year. IBM reported $1 billion in AI consulting revenue last year, while Accenture and KPMG earned $300 million and $650 million, respectively, from AI services in recent periods, with KPMG's earnings noted over the past 6 months. This trend highlights the increasing reliance of companies on external expertise to navigate and implement AI technologies.
