America’s AI Boom Is Squeezing Main Street | Weekly Roundup

AI is supporting nominal GDP growth and keeping technology and AI-linked assets resilient, but the expansion is unusually dependent on hyperscaler infrastructure spending. Hyperscaler AI capex grew more than 90% year over year in 2026 but is forecast to slow to roughly 30%–35%, while electricity, oil, and commodity constraints could limit further growth.

The episode argues that rising AI spending may overstate real economic expansion because part of the increase reflects higher input prices: Amazon said memory costs would absorb 30% of its 2026 AI data-center spending, versus 8% in 2023–24, and roughly $25 billion of Microsoft’s $190 billion guidance was attributed to higher prices. Google’s earnings-per-share growth was also described as partly reflecting higher valuations for AI-lab investments rather than solely operating gains.

Treasury repricing was attributed primarily to markets pricing a higher Federal Reserve terminal rate rather than a major increase in inflation expectations or fiscal concerns. With nominal GDP at 6.6%, credit growth at 3%, and the 30-year Treasury yield rising from 4.6% to 5.6% in six months, the discussion describes long-term financing costs as moving materially higher.

The speakers describe a difficult policy tradeoff: softer PCE data and core inflation measures moving toward 2% could give the Fed short-term breathing room, but jobs and inflation could remain hot for one to three months, limiting its ability to ease. They also argue that renewed quantitative easing or yield-curve control could push liquidity into commodities, lift yields, and undermine the financial conditions those policies were intended to improve.

Housing is exposed to the long-end sell-off because higher mortgage costs reduce the purchasing power of households that rely on financing, with the discussion estimating that they can afford approximately 11% less house. The speakers warn that a further bond sell-off could push mortgage rates to 7%–7.5%, while simply cutting rates could increase bond and mortgage-backed-securities volatility.
