The Takeaway
In the current hype cycle, every company wants to claim they are 'AI-powered' to boost their stock price. This paper proves that this 'AI washing' works in the short term, but the market eventually sniffs out the lie. Companies that exaggerate their AI tech end up suffering from sustained underperformance once the truth comes out. It’s a built-in 'bullshit detector' in the financial system. For investors, it’s a reminder that a fancy 'AI' label on a press release is often a sign of a company that is desperate, not innovative.
From the abstract
As firms increasingly exaggerate artificial intelligence (AI) adoption in disclosures, we analyze market responses to unsubstantiated AI claims. Using BERT-based text classification and AI patent data for U.S. firms (2018-2023), we find that such narratives initially attract investors but ultimately yield negative market reactions and sustained underperformance. Results demonstrate market penalties for AI overclaiming through both short-term investor responses and long-term operational outcomes,
