# PwC reports found to contain AI-fabricated sources, joining Big Four pattern

*2026-07-29 · Source: [The Decoder](https://the-decoder.com/pwc-has-allegedly-published-ai-generated-reports-containing-false-or-fabricated-sources/)*

GPTZero found fabricated sources and false claims in four PwC Middle East reports, with one governance report scoring 84% AI-generated. That report also promoted a PwC product using unverified customer references. KPMG, Deloitte, and EY have faced similar findings, meaning all Big Four consultancies are now implicated.

**Why it matters:** Professional-services firms are high-stakes users of AI because their reports underpin corporate and government decisions, so unchecked hallucinations there carry outsized real-world consequences. The pattern spanning all Big Four suggests inadequate AI verification processes industry-wide rather than an isolated lapse, and will likely accelerate calls for mandatory AI-disclosure and fact-checking standards in consulting.

**Topics:** policy, research
