The semis cohort took a broadside into today's Fed decision. AMD closed -8.2%, Micron -8.9%, Corning -12.1%, Bloom Energy -11.3% – every AI-adjacent industrial name that isn't NVDA itself. Yet the S&P inched green (+0.21%) and the Dow ripped +1.0% as money rotated into Coca-Cola, Boeing and Berkshire. This is the AI trade fracturing without the index flinching. And in roughly six hours, new Fed Chair Kevin Warsh walks up to the podium for the first time – the last time markets heard from him with this much on the line, he was one of the most hawkish voices in the room.

What moved overnight

The tape read like two markets stitched together. Under the hood, the AI industrial complex bled: AMD -8.2%, Micron -8.9%, the SOXX ETF -4.8%, the SMH -3.5%. Reuters' morning bid framed it bluntly: chips are jolted, and the momentum in AI is shifting. Corning – the specialty-glass supplier stitched into every AI datacenter buildout – dropped 12% on a soft print. Bloom Energy, the fuel-cell play riding the datacenter-power narrative, lost 11%.

Above them, the index-level story was different. The Dow closed +1.0% led by defensives; Coca-Cola +5.0%, Boeing +4.8%, Berkshire +3.1%. Rates cooperated – the 10-year drifted a handful of basis points lower to 4.60% and the VIX sagged to 18.2, a level that says nobody is panicking, they are just repositioning. Crude took the sharpest cross-asset move at -4.3% on the day as a growth-scare bid met OPEC supply chatter. Bitcoin was flat at $63.9k. Apple briefly kissed a $5 trillion market cap in the session – the second company ever to touch it – a headline that would have led every tape three years ago but landed as an afterthought under the chip carnage.

Trending in markets right now

Social conversations are circling one question: has the AI trade finally cracked, or is this a Fed-day squaring? The dominant chatter online is threading two data points that broke within twenty-four hours of each other. First, the Reuters framing shift – "momentum shifts in AI" is a very different sentence than the one being written a month ago. Second, Business Insider reported that Amazon is quietly winding down most of its flagship AI models in a strategy overhaul. Retail is asking whether the hyperscaler capex arms race is entering its digestion phase; the more skeptical crowd is asking whether the whole cohort was priced for a run-rate it can't hold.

Google search interest is surging in phrases like "AI capex peak" and "Micron guidance" – both leading indicators that the crowd has caught the story rather than being surprised by it. Yesterday's Yahoo trending tickers reflected the split cleanly: Corning and Bloom Energy dominated the losers, while Lucid (+21% on unrelated EV news) and Ionic Digital (+22%) were the retail-flow standouts on the up side.

Three things to watch today

Fed decision, 2pm ET. Consensus is hold – the CME FedWatch curve has priced no move. What matters isn't the decision, it's Chair Warsh's first press conference in the role. Investor's Business Daily flagged that a surprise hike can't be entirely ruled out; more likely, markets read the tone of his inflation language for hawkish drift. A hawkish tilt sends chips lower and yields higher.

Meta earnings, after the close. With Meta already -8% on the week and the AI capex question live, the earnings release is the referendum. The tell isn't EPS – it's the 2026 capex guide relative to the prior annualised pace. Any moderation is jet fuel for the AI-digestion thesis; a re-up cools it.

Micron and AMD tape-check. Two of yesterday's biggest chip losers open with no fresh catalyst. If they bounce hard, this was Fed-day de-risking rather than a regime break. If they leak lower on no news, the momentum shift is structural and the SMH/SPX ratio will have something to say about the second half of the year.

Bottom line

The market isn't down, but the market's leadership just changed hands mid-session. Chips lost the baton; defensives picked it up. Whether that's a one-day rotation or the start of a regime shift depends on two things landing in the next twelve hours – Warsh's tone at 2:30pm ET and Meta's capex line after the close. Watch the SMH/SPX ratio rather than the SPX headline. If chips fail to bounce after Warsh speaks and Meta trims capex, the trade that carried this market for eighteen months has to prove it can do it again from a lower base.
