Remember when everyone thought the economy was unstoppable? Yeah, about that. David Rosenberg, the economist who’s been the Cassandra of Wall Street since 2022, is back with another cheerful prediction: buckle up for a “very significant” recession in 2027.
Here’s the thing—the US economy has been running on two energy drinks: massive fiscal stimulus and the AI spending spree that’s made tech CEOs feel like kids in a candy store. But both are about to run dry, and when they do, things could get messy.
Let’s break down the stimulus first. Trump’s “One Big Beautiful Bill” extended those 2017 tax cuts and threw in a bunch of other goodies designed to juice the economy. It was supposed to boost GDP by 1.2 percentage points. Sounds great, right? Except Rosenberg thinks this gravy train derails after the midterm elections in November. If Democrats take control of Congress—which he thinks is likely—we’re looking at gridlock. And gridlock means no more stimulus. By 2027, that support just… vanishes.
Then there’s the AI capex bonanza. Amazon, Google, Meta, and Microsoft are collectively dropping nearly $600 billion on AI infrastructure this year alone. That’s a *lot* of money flowing through the economy. But here’s the problem: Rosenberg estimates that AI spending has been responsible for roughly 90% of all economic growth recently (when you factor in the wealth effect from tech stocks skyrocketing). And that capex boom is peaking *right now*. Once it starts declining, we’re removing what’s basically been the economy’s life support system.
“We’re going to be removing two crutches next year,” Rosenberg said. Enjoy the capex boom while it lasts—because it won’t.
The warning signs are already flashing. Real GDP growth slowed to 1.4% in Q4, down from 4.4% the quarter before. That’s not a gentle deceleration; that’s a red light. Meanwhile, Americans are getting squeezed. Hiring has slowed, layoffs are climbing, and the personal savings rate has tanked to 3.6%—down 150 basis points from the start of 2025. People are running out of cash.
Here’s where it gets really interesting: if the stock market takes a meaningful hit, that could be the domino that triggers everything. When people feel poorer (because their portfolios are shrinking), they spend less. And when consumers stop spending, the economy stops growing. Rosenberg put it bluntly: “No job growth, no income growth. Imagine if people were forced to tighten their belts and spend money in line with their real incomes.”
The good news? There’s a brief window. Americans will get tax refunds this year, which could give the economy a “lifeline” of two to three months. But that’s basically a sugar rush before the crash.
Is Rosenberg right? Maybe. Maybe not. But the fact that recession warnings are trickling back into Wall Street conversations—especially amid the Iran war volatility—suggests the market is starting to take this seriously. And when the smartest people in the room start sounding the alarm, it’s probably worth listening.
