Rising yields threaten to derail tech and AI stock rally

There’s a tug-of-war happening in financial markets right now. On one side: surging Treasury yields fueled by stubborn inflation data. On the other: an AI stock rally that refuses to quit despite macro headwinds.

The US 10-year Treasury yield has climbed to roughly 4.45-4.5%, its highest level since mid-2025, following hotter-than-expected inflation data and a broader global bond market selloff. That kind of move tends to be kryptonite for high-growth tech stocks, whose valuations depend heavily on discounting future earnings.

The AI trade is drowning out everything else

Here’s a number that should make you pause: nine of the top ten returning US stocks since the end of 2024 are AI-related. That’s not a diversified rally. That’s a one-theme market wearing different jerseys.

Semiconductors, the picks-and-shovels play of the AI boom, sit at the center of the trade. Companies building chips, running data centers, and supplying the infrastructure for large language models have attracted enormous inflows. NVIDIA’s upcoming earnings report is being treated as something close to an economic indicator unto itself, with expectations that strong results could provide another leg up for the entire AI complex.

The bull case is grounded in real fundamentals. These companies are posting genuine revenue growth. Capital expenditure commitments for AI and data center infrastructure are running at historic levels. The earnings are actually showing up. But they are showing up for a very small number of stocks.

Market breadth tells a different story

Less than 50% of S&P 500 constituents are currently trading above their key moving averages. Fewer than half the stocks in America’s benchmark index are in healthy technical shape, even as the index itself has been pushing toward record highs.

Rising bond yields are the key risk to this setup. When the 10-year yield pushes higher, it raises the cost of capital across the economy, compresses equity multiples, and gives risk-averse investors a reason to park money in bonds instead of stocks. The yield spike this time around was triggered by hotter-than-expected inflation data, compounded by a broader global bond market selloff. Persistent inflation makes it harder for the Federal Reserve to cut rates, which in turn keeps yields elevated for longer.

The disconnect investors are betting through

Strategists have pointed to an important nuance. The opportunity isn’t just in the obvious AI winners. It may increasingly be in the structural bottlenecks of the AI supply chain: power infrastructure, cooling systems, specialized networking equipment. These are areas where demand is running ahead of supply and where pricing power could prove more durable than in the attention-grabbing chip names.

Concentration risk is real. When nine of the top ten performing stocks share the same thesis, a single narrative shift — whether it’s a disappointing earnings report, a regulatory surprise, or a spike in yields — can unwind months of gains in days.

What this means for investors

The weak breadth beneath the surface of the S&P 500 is perhaps the most important signal to watch. Historically, narrow markets tend to resolve themselves with a pullback in the leaders rather than a catch-up from the laggards.

NVIDIA’s earnings report will be a near-term catalyst one way or the other. Strong numbers and forward guidance could give AI bulls enough ammunition to push through the yield headwinds. A miss, or even guidance that merely meets expectations, could be the trigger that reprices risk across the entire sector.

Higher yields typically strengthen the dollar and reduce appetite for risk assets. Bitcoin and digital assets have increasingly correlated with tech-sector risk sentiment, meaning a yield-driven selloff in AI stocks could create ripple effects well beyond equities.
