Nasdaq Hits Record High as Chip Rally and AI Spending Boom Continue

Wall Street's AI-driven rally just hit another milestone. The Nasdaq 100 climbed to its first record high since June, powered by a renewed surge in chipmaker stocks, while Asian markets extended a six-day winning streak overnight.

A Chip-Led Rally

The latest leg of the rally has been driven largely by semiconductor stocks, with bellwether names like Samsung Electronics and SK Hynix climbing in Asian trading. Falling oil prices also gave markets a boost, as easing tensions added to a generally positive mood among investors heading into the final stretch of the quarter.

AI Spending Is Now a Major Piece of the US Economy

Behind the market rally is a much bigger story: how much of the US economy is now being driven by AI infrastructure spending.  According to data from Goldman Sachs, investment tied to the AI build-out has accounted for roughly one-fifth of total US economic growth so far in 2026.

The scale of that spending is staggering. The four largest hyperscale cloud companies — Alphabet, Amazon, Meta, and Microsoft — are expected to spend roughly $800 billion combined on capital expenditures this year alone. That's about ten times what these same companies spent just seven years ago, in 2019.

Where the Money Is Coming From

Increasingly, that spending isn't just coming from company cash reserves — it's being financed through debt. Hyperscalers are expected to issue around $250 billion in investment-grade debt globally by the end of 2026 to help fund their AI infrastructure buildout.   Economists are watching this trend closely, since sustaining that level of investment will require major growth in the cash flow these companies generate from their AI businesses.

Private AI Valuations Are Reaching Historic Levels

The AI boom's scale isn't limited to public markets either. Private AI companies are being valued at levels rarely seen in corporate history.     OpenAI is reportedly raising funds at a $1.2 trillion valuation, while other leading AI and space companies are similarly approaching or exceeding the trillion-dollar mark in private valuations. Combined, some of the largest AI-related private companies now carry a combined valuation north of $5 trillion — a figure larger than the total value of every IPO completed between 1980 and 2025, according to data cited by the Financial Times.

Why This Matters

Markets are essentially betting that today's massive AI spending will pay off in future profits — but the sheer size of that bet raises real questions. If hyperscalers can't grow their cash flow quickly enough to match their spending and debt levels, some analysts warn the AI investment boom could become a source of financial strain rather than pure upside. For now, though, record highs on the Nasdaq suggest investor confidence in the AI story remains strong.
