OpenAI dominated enterprise AI for several months. Then in April, something changed. According to data published by Ramp’s AI Index, Anthropic’s Claude surpassed ChatGPT in business adoption for the first time, reaching 34.4% market penetration compared to 32.3% for OpenAI.
The reversal was so dramatic that it surprised observers who thought OpenAI’s corporate dominance was inevitable.
Anthropic is currently capitalizing on this strength through an agreement with consulting giant PwC, which will see Anthropic become Claude’s sales force across corporate America.
Thursday’s new announcement highlights one major goal: training 30,000 PwC employees on Claude Code, Anthropic’s recently released agent AI system that will be rolled out globally to train 364,000 PwC employees.
Anthropic and PwC will establish a new center of excellence dedicated to integrating AI into clients’ operating models. Specifically, efforts will be made in three different areas: developing agent AI systems, streamlining the deal-making process, and overhauling the way companies organize their operations.
The company leveraged Claude with real customers to reduce their underwriting process from 10 weeks to just 10 days.
Security tasks that used to take hours now take minutes. This is not a slogan, but a real-life example that Anthropic CEO Dario Amodei mentioned when announcing the partnership.
Within a month, in May, Anthropic secured a $1.5 billion investment in an AI services joint venture with Blackstone, Hellman & Friedman, and Goldman Sachs Asset Management. This allows Anthropic to fund not only the biggest names on Wall Street, but also the hundreds of portfolio companies owned by these companies that are under pressure to prove productivity improvements using AI technology.
Meanwhile, OpenAI has decided to directly partner with BCG, Accenture, Capgemini, and PwC. Google recently pledged $750 million to help McKinsey, Accenture, and Deloitte launch their own agent AI.
