A selloff in chip stocks erased roughly $500 billion in value while government bonds rallied and oil spiked.
What happened
US equity futures were mixed pre-market as traders dumped semiconductor stocks on AI overspending fears. The chip pullback moved roughly $500 billion in market value. At the same time, government bond prices rose sharply, pushing yields down 1.3% over the past week, and oil prices surged 5%.
Why it matters
The chip rout shows investors repricing how much the AI buildout is actually worth, directly hitting the sector that led markets higher. The simultaneous bond rally and oil spike pull in opposite directions: falling yields support growth stocks by making future profits worth more today, but rising crude squeezes margins and keeps inflation alive, raising the odds the Fed lifts rates instead of cutting.
The case against
The pullback is still within an uptrend for chips. High-yield bonds are only underperforming investment-grade by 1.3%, a stress signal that is building but not yet at panic levels. This could be profit-taking in an overbought sector, not the start of a sustained unwind.
What settles it
Whether the chip pullback breaks below its uptrend and corporate bond stress spills from 1.3% into a wider spread.
