Most of the evidence is market reporting: sharp sell-offs, rising debt and heavy cash burn at AI companies. Official statistics and a few studies tie AI to economic growth. TRV-2026-2399TRV-2026-1509TRV-2026-1056TRV-2026-0139 Whether the recent falls mark a bust or a reset is still unresolved. TRV-2026-1973
UK GDP rose 0.4% in July 2026 against forecasts of zero growth, and the ONS pointed to computer programming and consulting firms in AI and cloud computing. TRV-2026-1056 China's GDP grew 4.5% from July to September, with analysts crediting AI-related electronics exports, though domestic demand and property investment remain weak. TRV-2026-1880 An observational study of G20 economies found more AI patents were associated with faster GDP per capita growth, at a diminishing rate, though the authors say patents are an imperfect measure of AI. TRV-2026-0139 A study of 138 AI investment announcements by FTSE 100 companies found no significant announcement day share-price gain, while a firm-year study of Chinese listed firms found more AI linked to lower crash risk.

A tech-led sell-off wiped more than $3.2tn from US stock values in a day, with the Nasdaq down 5.5% and the S&P 500 down 4.4%, news reports say. TRV-2026-2399 The Bank of England's Financial Policy Committee said large AI players took on $450bn of debt between January and September, and the IMF warned an AI share correction could spread across global markets. TRV-2026-1509TRV-2026-1328 Amazon's free cash flow fell to negative $7.6bn in Q2 2026 as it bought AI racks it cannot yet power, and Figma's gross margins slid from above 90% to the mid 80% range under AI spending. TRV-2026-2023TRV-2026-1449 Projects stalled too: Microsoft pulled out of Nscale's Loughton datacentre after UK Power Networks said it could not supply enough electricity until the early to mid 2030s, and OpenAI put Stargate UK on hold.

Anthropic's stock market filing reports audited revenue of $16.286bn in the first half of 2026 against an $80bn net loss, and much of that loss stemmed from a one-off $72.4bn charge. TRV-2026-2268TRV-2026-2274 Claims that many of the more than 200 neocloud firms will fail come largely from Elon Musk, whose companies operate datacentres. TRV-2026-2272 The midterms' effect on datacentres is mostly expectation: a Guardian column expects ballot measures to strain valuations inflated by AI, while the White House argued they would largely not affect existing projects. TRV-2026-2431TRV-2026-2405 A Guardian callout drew more than 150 self-selected respondents who said they worry their 401(k) savings will be pulled into SpaceX and other AI firms. TRV-2026-0214
