A speculative scenario outlining the potential economic fallout from rapid advances in artificial intelligence triggered a sharp sell-off in US stock markets this week, underscoring investor anxieties about the disruptive potential of the technology. The catalyst was a 7,000-word essay, “The 2028 Global Intelligence Crisis,” published on Substack by James van Geelen, founder of Citrini Research.
The Dow Jones Industrial Average fell 822 points on , and the S&P 500 finished down more than 1%, with financial stocks experiencing their steepest decline since . A leading software exchange-traded fund dropped over 4%. The market reaction, while seemingly disproportionate to a hypothetical exercise, highlights a growing unease about the speed and breadth of AI’s development.
A Deflationary Cascade
Van Geelen’s essay, framed as a retrospective from , posits a future where increasingly autonomous AI agents dramatically reshape the US economy. The core thesis centers on a “deflationary cascade” – a scenario where AI doesn’t simply augment human labor, but replaces it so efficiently that it destabilizes the broader economic system. The report stresses It’s a “thought exercise, not a prediction.”
Key Triggers for Market Anxiety
The scenario identifies several key triggers that resonated with investors. First, the anticipated “death of the middleman” as AI-powered tools automate tasks currently performed by human intermediaries. The report specifically cites advancements in systems like Anthropic’s Claude Code and OpenAI’s Codex as evidence of this trend. This disruption, according to Citrini, would extend beyond the software sector to industries reliant on transaction “friction,” such as travel booking, insurance, and real estate.
The essay suggests that AI agents could allow companies to manage workflows internally at lower cost, reducing demand for platforms like Monday.com, Zapier, and Asana, and forcing vendors like Oracle into sharper price competition. Direct consumer-to-provider transactions facilitated by AI could bypass companies like Uber and DoorDash, while pressure on payment networks like Visa and Mastercard could arise from a shift towards lower-cost cryptocurrency rails.
Mass White-Collar Unemployment
A central concern outlined in the report is the potential for widespread white-collar job losses. Citrini argues that, unlike previous technological revolutions, AI may not create as many jobs as it destroys. The report states that “AI is now a general intelligence that improves at the very tasks humans would redeploy to. Displaced coders cannot simply move to ‘AI management’ because AI is already capable of that.”
This wave of layoffs, the scenario suggests, would lead to weaker consumer spending as displaced workers struggle to find comparable employment. Companies, in turn, would respond by doubling down on automation to cut costs, creating a self-reinforcing cycle with “no natural brake.”
Financial System Strain
The report extends the potential shockwaves into the private credit and housing sectors. Many software firms have been financed by private credit lenders based on assumptions of steady, long-term revenue growth. If AI undermines those assumptions, defaults could surge, putting pressure on asset managers like Hellman & Friedman and Permira, which have significant exposure to software-backed loans.
Simultaneously, widespread layoffs would strain household finances, leading to mortgage defaults and further tightening credit conditions. This combination of factors, according to Citrini, could ultimately trigger a significant economic downturn, with the S&P 500 potentially falling 57% by late .
“Ghost GDP” and Social Tensions
Citrini also flags a potential imbalance between headline economic indicators and the lived experience of many households. The report highlights the possibility of “ghost GDP” – economic output driven by AI-powered productivity gains that doesn’t translate into increased income or spending for the broader population.
The firm warns that this disconnect between corporate profits and household finances could exacerbate social and political tensions, with anger directed less at Wall Street and more at Silicon Valley.
Market Reaction and Reassurance
The report’s impact was immediate. Shares of companies specifically mentioned in the essay experienced significant declines. DoorDash fell approximately 7%, while Visa and Mastercard dropped 4.6% and 5.8% respectively. IBM suffered its worst one-day drop in decades.
Following the sell-off, van Geelen emphasized that the report was a scenario, not a forecast, and intended to spark a conversation about the potential consequences of increasingly powerful AI. Ed Yardeni of Yardeni Research offered a more optimistic perspective, stating that he believes AI is “augmenting workers’ productivity rather than making them extinct.”
The episode serves as a stark reminder of the growing sensitivity surrounding AI’s potential impact on the economy and the financial markets. While the long-term effects remain uncertain, the recent market reaction underscores the need for continued vigilance and a nuanced understanding of the risks and opportunities presented by this rapidly evolving technology.
