Citrini Research's viral "scenario" imagines AI agents dismantling the US economy piece by piece, from wiping out white-collar jobs to triggering a mortgage crisis and a 57% stock market crash by 2028. Speculative as it is, markets are already reacting — and that may be the most unsettling part of all.

A speculative blog post from an obscure research firm has sent shockwaves through US markets — and Wall Street is paying attention.

Citrini Research, a small firm focused on economic "megatrends," published a Substack scenario imagining how AI could unravel the US economy by June 2028. The firm was careful to call it a "scenario, not a prediction," but that disclaimer did little to calm investors. The S&P dropped over 1% on Monday, and companies like Uber, DoorDash, Mastercard, and American Express each shed between 4–6% after being named in the report.

The scenario unfolds in stages. First, increasingly capable AI agents eliminate the "friction" that middlemen businesses depend on — think travel agencies, food delivery apps, and payment processors. Consumers and developers, empowered by AI, simply build their own tools or route around legacy platforms entirely.

Next comes mass white-collar unemployment. Unlike past technological disruptions, AI improves at the very jobs displaced workers might pivot to — including managing AI itself. Laid-off professionals flood the gig economy, wages fall, and consumer spending collapses. Companies respond by investing in more AI rather than more people, creating what Citrini calls "a feedback loop with no natural brake."

The crisis then bleeds into financial markets. Software companies buckle under AI disruption, triggering defaults in private credit markets. Meanwhile, unemployed white-collar workers can no longer service their mortgages. By late 2027, a market crash wipes out 57% of the S&P 500.

The scenario ends with "Occupy Silicon Valley" protests outside OpenAI and Anthropic's offices — and a concept Citrini dubs ghost GDP: economic output that enriches tech giants but never reaches ordinary people.

Many experts say AI isn't yet capable of triggering this chain of events. But as one analyst put it: markets that shrugged off wars and banking crises were rattled by a Substack post. That alone says something.
