Highlights

Federal Reserve data show U.S. household wealth rising 16.5% or $26 trillion through mid-2026, with less than $0.5 trillion reaching the least-wealthy half.
AI-driven stock market gains disproportionately benefit the top 1%, while most households rely on wages and see limited direct impact from the surge.
Real consumer spending is expanding at a pre-pandemic pace despite price pressures from tariffs, energy, and the AI boom, keeping public sentiment weak.

Wealth gains concentrate as AI spending accelerates

As reported by Reuters, the artificial intelligence buildout is driving a historic level of capital investment in the U.S., while much of the financial upside is flowing disproportionately to wealthier households.

Federal Reserve data cited in the report show household wealth rises 16.5% from the end of Joe Biden's administration through mid-2026, an increase of about $26 trillion. Less than half a trillion dollars of that goes to the least-wealthy half of households, though that still amounts to a gain of about 10%. Between the end of Biden's term and the second quarter of 2026, only the top 1% secures a larger share of national wealth.

The stock market rally helps support consumer activity across the economy, but it also sharpens questions about how far AI-linked gains reach beyond asset owners. For most households, wages rather than investments remain the main source of income, limiting the direct benefit from the market surge.

Affordability strains cloud consumer outlook

Consumer spending continues to rise in dollar terms and is growing faster than before the pandemic, suggesting households are still managing higher costs. Research from major banks, the Richmond Federal Reserve and the New York Fed points to mixed evidence on whether lower-income Americans are materially falling behind, with little sign so far of a broader credit crisis among less well-off borrowers.

On an inflation-adjusted basis, however, real spending is expanding at roughly the same pace as before the pandemic. The widening gap between nominal and real spending underscores how inflation erodes purchasing power, a dynamic economists say is a major reason public sentiment remains weak despite continued spending.

Price pressures have persisted over the past 20 months as import tariffs, energy costs linked to the Iran war and the AI boom move through the economy. While households can adapt to rising prices for routine purchases, larger expenses such as home ownership carry broader consequences for family formation, long-term wealth building and perceptions of economic progress.

Our earlier coverage of the S&P 500’s narrow, AI-led rally highlighted how index gains in 2026 were concentrated in a small group of chipmakers and mega-cap tech names while many constituents lagged or fell. We noted that this kind of top-heavy advance can amplify the wealth effect for asset holders, raising the risk that any reversal in AI-linked leaders could spill over into consumer spending and the wider economy.
