Everything funnels toward Wednesday’s rate decision. But before the Fed even speaks, an AI-safety scare is already tearing through the chips that carried this market. Here’s the map for the week ahead.
There are Fed weeks, and then there are weeks like this one. Wednesday afternoon the Federal Open Market Committee is expected to raise interest rates for the first time since 2023 — a move that would have sounded absurd six months ago, when the only question was the pace of cuts. That alone would define the week. Instead, the market didn’t even wait for the opening bell to find its second story: AI stocks are selling off worldwide after the industry’s own leaders spent the weekend calling for a slowdown.
So this is the map. One scheduled event we can circle on the calendar, one unscheduled shock already in motion, and a bond market sitting on a knife’s edge with the 10-year Treasury yield touching 5.00% this morning for the first time in three years. Let’s walk through what actually matters.
The FOMC meets Monday and Tuesday and announces Wednesday. Coming out of Jackson Hole, futures swung hard toward a quarter-point hike, and nothing in Friday’s in-line CPI argued against it. A 25bp increase would lift the target range to 3.75%–4.00%. But the decision itself is almost the easy part — what the market will trade is everything around it: the updated Summary of Economic Projections, the dot plot, and Chair Warsh’s press conference. The question is not really “do they hike” but “how many more do the dots pencil in, and how hawkish does Warsh sound defending it.”
| Wednesday's decision tree | Market read |
|---|---|
| Hike + hawkish dots + firm Warsh | Risk-off, yields up |
| Hike + one-and-done framing | Relief rally |
| Hold (very unlikely) | Sharp bounce, credibility risk |
While everyone watches the Fed, the tape is being written by semiconductors. Over the weekend Anthropic’s Dario Amodei called for a deliberate, global slowdown in AI development; Sam Altman and Elon Musk backed the idea, and Altman said OpenAI would not go public this year. The read-through to demand for chips and data centers was instant and brutal. Nvidia — the most valuable public company on earth — is down more than 3% and is the single heaviest weight on the market, shedding well over $150 billion in value. The Philadelphia Semiconductor Index is having its worst day since July.
Notice that last row. This is not an indiscriminate tech wipeout — it is a rotation. Money leaving chips is finding a home in cybersecurity and software, the corners of tech that stand to benefit from a world more worried about AI risk. That rotation is why the Nasdaq is holding up far better than the semis alone would suggest, and it’s the single most important tell for how this week trades: as long as the selling stays a rotation and not a liquidation, the broad market has a floor.
Don’t lose the bond market in the noise. The 10-year yield touching 5.00% this morning — driven by oil’s latest climb toward $110 before it settled back near $105.68 — is the mechanism that connects both stories. Five percent is the benchmark for mortgages and corporate borrowing, and it is the discount rate that decides what a dollar of future AI earnings is worth today. Higher yields punish exactly the long-duration growth names already under pressure from the safety scare. If the 10-year breaks and holds above 5%, it does more damage to this market than any single Fed sentence.
Monday and Tuesday: position ahead of the Fed and watch whether the chip selling stays contained to a rotation. Wednesday 2 p.m.: the decision, the dots, and Warsh. Thursday and Friday: the reaction — and note that Friday is triple witching, the quarterly expiration of options and futures that reliably amplifies volume and can exaggerate moves into the close. Trade the reaction, not the headline.
This is a two-catalyst week stacked on a fragile bond market. Base case: a 25bp hike Wednesday to 3.75%–4.00%, with the dot plot and Warsh’s tone doing the real market-moving. The live wildcard is the AI-safety selloff — watch whether it stays a rotation into cyber and software (a floor) or curdles into broad de-risking (no floor). And keep one eye on the 10-year: above 5% and holding, everything else gets harder.
