Key Bullet Points:
- Marvell Technology (MRVL) crashed 8.7% to $189 on Thursday — losing nearly a third of its value in 30 days despite a 125% year-to-date run — as hyperscaler capex revision fears triggered a sector-wide AI chip selloff that has now erased over $1 trillion in semiconductor market capitalization
- The Philadelphia Semiconductor Index (SOX) dropped 3.5% as AMD fell 4.2%, Broadcom and Intel slid, and even TSMC fell 2.1% after posting record Q2 earnings and pledging an additional $100 billion in Arizona investment — the first time a blowout chip earnings report has been immediately sold into during this entire AI cycle
- SpaceX (SPCX) plunged to approximately $131 on Thursday — now well below its $135 IPO debut price and down over 42% from its post-listing high of $225.64 — with the first wave of lockup expirations arriving in early August, threatening to flood the market with insider shares
- The Dow rose 0.28% to 52,806 while the Nasdaq sank 1% to 26,054 and the S&P 500 fell 0.39% to 7,544 — the widest daily divergence of the year — as old-economy stocks (UnitedHealth +7%, Abbott +12%) soared and AI darlings cratered
- Netflix reports Q2 after Thursday's close with the stock down 18.7% in 2026, options traders pricing an 8% post-earnings swing, and the market desperate for proof that Big Tech can grow through a chip-sector reckoning
The AI Trade Is Cracking — and Nobody Is Safe
For two years, the trade was simple: buy anything connected to artificial intelligence chips. Nvidia. AMD. Broadcom. Marvell. The semiconductor index tripled. Fortunes were made. Questions about profitability, returns on investment, and whether any of this spending would ever generate real revenue were luxuries for later.
Later just arrived.
Marvell Technology fell 8.7% on Thursday to $189, extending a rout that has erased nearly a third of the stock's value in 30 days. To put that in perspective: Marvell was still up 125% on the year heading into this selloff. It was considered one of the safest AI chip plays — a custom silicon designer with deep hyperscaler relationships and a product roadmap that read like a Wall Street wish list.
None of that mattered this week.
The trigger was hyperscaler capex revision fears — rumors and reporting that the biggest cloud providers, the companies spending tens of billions on AI infrastructure, are beginning to revise their capital expenditure forecasts. Not cut them. Revise them. In the current environment, that distinction is irrelevant. Any hint that the spending bonanza might slow — even by a quarter, even from one customer — sends the entire semiconductor supply chain into a repricing event.
And that is exactly what happened.
The Semiconductor Massacre, by the Numbers
The Philadelphia Semiconductor Index dropped 3.5% on Thursday alone. AMD fell 4.2%. Broadcom slid. Intel dropped. Micron had already crashed 8% on Wednesday on China competition fears, dragging AMD and Intel down 6% each in a sympathy selloff that looked more like panic.
But the most alarming signal came from TSMC.
Taiwan Semiconductor reported blowout Q2 earnings Thursday morning — record revenue of $40.2 billion, EPS of $4.31 per ADR unit beating consensus, revenue up 36% year-over-year. The company pledged an additional $100 billion in Arizona chip factory investment, on top of $165 billion already committed, bringing its total U.S. investment to $265 billion.
The stock fell 2.1%.
That has never happened during this AI cycle. Every previous TSMC beat — and there have been many — was met with buying. This time, investors focused on the company's raised capex budget of $60–$64 billion and asked a question that has been quietly building for months: if building AI infrastructure costs this much, when does anyone get paid back?
TSMC's CEO C.C. Wei tried to reassure analysts. "Our customers continue to provide us with very strong signals and a positive outlook," he said on the earnings call. The market heard it. It just didn't care.
SpaceX Keeps Falling
The IPO that was supposed to define a generation hit another ugly milestone Thursday.
SpaceX shares plunged to approximately $131, falling further below the $135 IPO debut price for a second consecutive session. From its post-listing high of $225.64 to Thursday's lows, the stock has now declined more than 42%, wiping out over $700 billion in market capitalization.
The damage is structural, not just sentimental. The first wave of insider lockup expirations arrives in early August, when shares tied to early investors and employees become tradeable. At $135, those locked shares represented the IPO price. At $131, they represent a loss. The incentive to sell — to capture what value remains before more supply hits the market — creates a gravity well that the stock cannot easily escape.
Everything lifting through December 8 takes the potentially tradeable float to 40% of the company. Elon Musk's holding and the rest of the 60% stay locked until mid-2027. For a stock with a $1.8 trillion valuation, that overhang is enormous.
Raymond James maintains a buy rating with a $242 target, implying 79% upside. Wall Street consensus agrees. But Wall Street consensus also said the IPO was a sure thing at $135.
The Great Split
Step back from any single stock and the pattern becomes unmistakable.
The Dow Jones Industrial Average rose 0.28% on Thursday to 52,806. UnitedHealth jumped 7% after crushing Q2 earnings and raising guidance. Abbott surged 12.1% on a strong beat. ManpowerGroup — an employment agency — exploded 33% higher. These are healthcare companies, industrials, staffing firms. The old economy.
The Nasdaq fell 1% to 26,054. The SOX dropped 3.5%. Marvell lost nearly a tenth of its value. The new economy.
The divergence was the widest of the year. And it wasn't random — it was rotational. Institutional money is leaving the AI hardware trade and moving into sectors that generate earnings the market can understand and verify. Hospitals that treat patients. Insurance companies that collect premiums. Staffing firms that place workers.
This is not the death of AI. It is the death of paying any price for AI exposure without demanding proof of return. The difference matters — but for anyone holding Marvell, AMD, or SpaceX, the difference also doesn't pay the bills.
The Week Ahead
Netflix reports Q2 after Thursday's close with the stock already down 18.7% in 2026. Options traders are pricing an 8% post-earnings move in either direction. Wall Street expects EPS of $0.79 on revenue of $12.59 billion. Netflix has missed earnings estimates in three of its last four quarters — and the stock has been punished every time.
The result matters beyond Netflix. In a market that is actively rotating out of growth and into value, a strong Netflix quarter could halt the bleeding. A miss would accelerate it.
Eli Lilly's $2.8 billion acquisition of psychedelic drugmaker AtaiBeckley — the largest pharma bet on psychedelics in history — signaled where the growth money is going next. And in the Strait of Hormuz, Iran released detained U.S. citizen Dena Karari after two years, even as U.S. daylight strikes intensified and Trump discussed a "massive offensive" from the Situation Room.
Brent crude held near $85. The ceasefire is dead. And the market that was supposed to only go up just split into two separate economies — one that is working, and one that is still trying to prove it will.
