Big Four firms including PwC and EY retract flawed AI-generated research reports
Several of Europe's Big Four consulting firms, including PwC, EY, and KPMG, have come under scrutiny after AI-generated errors were found in their published research. PwC's Middle East reports were found to contain hallucinated content and fabricated footnotes, with broken web links flagged by researchers.

The incidents expose a growing tension between firms marketing AI services and their own unreliable use of the same technology. The affected firms are now conducting reviews of their published research to check for inaccuracies.
