Shares in Uber, Mastercard and American Express fall on back of apocalypse scenario posted on Substack
U
S stock markets have been hit by a further wave of AI jitters, this time from yet another viral – and completely speculative – warning about the impact of the technology on the world’s largest economy.
The latest foreboding is from Citrini Research, a little-known US firm that provides insights on “transformative ‘megatrends’”. Its post on Substack, which it called a “scenario, not a prediction”, rattled investors by portraying a near future in which autonomous AI systems – or agents – upend the entire US economy, from jobs to markets and mortgages.
Citrini’s scenario begins now and ends in June 2028, with US unemployment cresting over 10% and an Occupy Silicon Valley movement setting up camp outside OpenAI and Anthropic’s offices. In the interim, a series of events triggered by the widespread use of AI agents guts software companies and ripples outwards, hitting private credit and mortgages, and leading to an unchecked downward spiral.
