AI can miss the evidence while markets finance the promise
Two new records describe the same structural problem at very different scales: AI is becoming consequential faster than its blind spots are becoming visible. In a peer-reviewed study, researchers evaluated Consensus, Ai2 Paper Finder, ChatGPT, Gemini, and Claude against a prospectively assembled, non-public gold-standard corpus. Across fifteen query formulations, median recall per query ranged from 7.2% to 42.2%. Even after pooling every query, platform recall ranged from 45.8% to 72.3%. Twelve percent of all relevant evidence was never retrieved by any platform, and conference proceedings were far more likely to disappear than journal articles: 38.9% versus 4.6%. The lesson is not that these tools are useless. It is that a fluent synthesis can hide an uneven evidence universe. On the same day, the Bank of England said rapid AI-related debt issuance is broadening capital-market exposure to AI capability, adoption, cyber incidents, and operational failures. Its record cites analyst estimates of roughly $450 billion in global AI-related debt issuance by early September, more than double all of 2025, and $4.1 trillion of debt-financed AI capital expenditure from 2026 through 2030. The Bank also says markets remained orderly after a July selloff and UK banks remain resilient. This is not a crash forecast. It is a visibility warning: healthcare tools can hide missing studies while financial structures hide leverage and circular exposure. Both systems need evidence maps before confidence becomes allocation.
