AI investment now claims a share of GDP nearly a third larger than internet investment did at the dot-com bubble's peak, according to economist Jared Bernstein.1 Tech and AI sectors are lifting aggregate economic growth. The rest of the economy is buckling.
30-year U.S. Treasury yields have crossed 5%. UK gilts have reached their highest levels since the 1990s. Services inflation holds stubbornly above 3% annually.2 The Federal Reserve faces leadership uncertainty as Chair Jerome Powell's term expires.
The Iran conflict has added $857 per year to the average American's gasoline costs in 2026.3 The national debt stands at $39 trillion. Rising debt service costs pressure a federal budget already stretched thin.
Goldman Sachs has flagged equity market fragility as rate-hike expectations reprice higher. Consumer sentiment is collapsing — notably among middle- and upper-income households, the most resilient spending segment through the post-pandemic recovery.4
The K-shape is sharpening fast. Companies with AI capabilities attract capital, talent, and compounding productivity gains. Firms without face a simultaneous squeeze from energy inflation, tighter credit, and wage pressure — with no offsetting productivity dividend.
Low pandemic-era rates had already hurt retirees dependent on fixed-income returns.2 Rising yields now create the mirror problem: homebuyers, small businesses, and leveraged companies face sharply higher borrowing costs. AI-heavy firms, meanwhile, increasingly self-fund from cash flows.
A partial U.S.-China tariff détente offers modest relief on goods prices.3 It doesn't offset multi-front inflation hitting energy, services, and healthcare simultaneously.
The structural gap between AI-enabled and traditional sectors now exceeds the scale of the dot-com divergence, by Bernstein's measure.1 That parallel carries a warning: the dot-com gap also collapsed, abruptly.
AI productivity gains are compounding faster than any prior technology cycle. But macroeconomic pressures on the non-AI half of the K are compounding too. When consumer sentiment breaks among higher-income households — historically the last line of spending resilience — aggregate demand becomes vulnerable regardless of what AI stocks are doing.
The post-pandemic Goldilocks era is over. AI adoption pace now determines which side of the K a company lands on.
