Synopsis US stock market crash today: The Nasdaq just delivered a sharp reality check to Wall Street. On June 9, 2026, the tech-heavy Nasdaq Composite plunged 2.17%, losing more than 560 points as AI and semiconductor stocks extended their recent sell-off. The S&P 500 fell 1.22%, shedding over 90 points, while the Dow Jones Industrial Average slipped 0.43%, down about 216 points. The Nasdaq 100 suffered the deepest damage, tumbling more than 750 points from its intraday high as investors rushed to lock in profits from the market's biggest AI winners. US stock market crash: The Nasdaq just handed investors a brutal reality check. On June 9, 2026, the tech-heavy index shed more than 560 points — a 2.17% decline — as chip stocks collapsed for the second week running, dragging the S&P 500 down 1.22% alongside it. The Nasdaq 100, which had opened strong near 29,679, finished the day closer to 28,662 after an intraday slide of over 750 points. This wasn't random noise. It was a sector-wide reckoning for stocks that had climbed so high, so fast, that any stumble turned into a freefall. The AI chip trade — the dominant market narrative of 2025 and early 2026 — is now confronting a question it has never had to answer: what happens when the euphoria meets the math? This Nasdaq chip stock selloff in June 2026 isn't just a number on a screen. It is a signal about how markets price technological revolutions — and how violently they reprice them. US stock market crash today: Marvell, Nvidia, and the Chip Stocks Leading the Nasdaq Decline Marvell Technology (MRVL) was the most visible casualty. After jumping nearly 10% on Monday on the back of AI infrastructure optimism, Marvell reversed hard Tuesday, sinking more than 12% to lead Nasdaq decliners. For context, approximately $1.4 trillion in market value was erased across the AI semiconductor sector during this week's selloff, with Nvidia alone losing $279 billion in market capitalization and Marvell plunging 17% in the initial Friday session alone. Tuesday's session compounded those losses. Nvidia (NVDA) opened nearly 1% higher before reversing to trade down 3.3%. Tesla, the Magnificent Seven's other gainer on Monday, fell 5.4%. Apple dropped more than 4%, still digesting a weak reception to its annual Worldwide Developers Conference. Every single member of the Magnificent Seven finished in the red. The iShares Semiconductor ETF (SOXX) was down 6% on the day — its third major leg lower in less than a week. The pattern is telling: the semiconductor sector tumbled 10% in a single session Friday, with Broadcom falling 12.6%, Marvell plunging 17%, Intel and AMD each falling around 11%, and Micron dropping 13% after losing 8% the session before. Live Events These aren't marginal moves in marginal stocks. These are the companies the market had crowned as the infrastructure of the future — and they are being repriced at speed. US stock market crash: What Actually Triggered This AI Chip Stock Collapse? The proximate cause traces back to Broadcom's earnings earlier in the week. A cautious AI chip outlook from Broadcom, coupled with a deepening memory chip crisis and a projected collapse in global smartphone demand, triggered the broader semiconductor sector decline. Despite the pullbacks, both AMD and Intel had delivered substantial year-to-date gains driven by the AI infrastructure boom, but now face heightened scrutiny over valuations and shifting market dynamics. That last phrase matters: valuations and shifting dynamics. Broadcom didn't announce disaster. It announced something more unsettling for an overheated market — uncertainty. In a sector where stocks had been priced for perfection, uncertainty functions like a trapdoor. There's a deeper structural issue at work too. Marvell, for instance, had traded as high as 83 times forward earnings at its January peak — a valuation that desperately needed a reset. The stock has now lost roughly 50% from those highs. The same dynamic played out across the semiconductor space. Investors had been paying tomorrow's prices for today's earnings, and now tomorrow keeps changing. The chip selloff also spread well beyond U.S. borders. South Korea's Kospi ended Friday's session 5.54% lower, with Samsung Electronics and SK Hynix dropping 6.40% and 9.92% respectively. ASML fell 3.8% and German chipmaker Infineon slumped more than 6%. This is a global repricing of the AI semiconductor trade, not a localized correction. The Iran War, Oil Prices, and What's Pressuring Markets Beyond Tech The chip selloff doesn't exist in a vacuum. Broader macroeconomic stress is amplifying every negative signal. Oil prices tumbled 3.4% Tuesday to around $88 a barrel after President Trump suggested a U.S.-Iran deal could come within days — only for markets to partially reverse those gains after he posted that Iran had shot down a U.S. Apache helicopter in the Strait of Hormuz. The contradiction captured the mood perfectly: every hopeful signal came with an asterisk. Meanwhile, Bitcoin fell below $61,000, off from overnight highs near $63,800, and touched below $60,000 for the first time since October 2024 on Friday. Risk appetite — across every asset class — is draining fast. The 10-year Treasury yield held near 4.53%, down slightly from Monday's close near 4.57%. Gold futures fell 1.8% to $4,285 an ounce. These are not the moves of a market confidently pricing in growth. They are the moves of a market hedging against a scenario it hasn't fully named yet. And that unnamed scenario has a date: Wednesday. The May Consumer Price Index is due from the Bureau of Labor Statistics, with forecasters expecting a 4.2% year-over-year increase — the highest annual inflation reading since April 2023. Core CPI is expected at 2.9%, up from 2.8% in April. The driver, unlike 2021, isn't supply chain chaos from COVID. This time it's the Iran war restricting oil supply and pushing energy prices — and those costs — into everything else. Is the AI Trade Over, or Just Repricing? The honest answer is: nobody knows yet. What the market is doing right now is not passing judgment on AI. It is passing judgment on what AI was priced to deliver. There is a significant difference. Despite the severity of the initial decline, semiconductor stocks showed remarkable resilience — by Monday, June 8, the Nasdaq had recovered nearly 0.9% as AI-related semiconductor firms reclaimed ground. This rapid stabilization suggested the selloff represented a technical correction rather than a fundamental reassessment of AI growth prospects. That recovery was then partially unwound on Tuesday. The pattern suggests neither a bubble pop nor a smooth correction — it suggests genuine disagreement among large investors about where fair value actually sits. What's undeniable: Marvell's data center end market revenue soared 78% in Q4 as the AI spending boom continued, and the company is projected to grow revenue 44% this year. Those numbers haven't changed. What's changed is what investors are willing to pay for them. What Investors Should Watch Before the Market Opens Thursday Three things matter most in the next 48 hours. First, Wednesday's CPI print. A 4.2% reading would rattle rate expectations and add pressure to already stretched tech valuations. Second, Oracle earnings after Wednesday's close — options markets are pricing an 11% swing in either direction, and any signal on AI infrastructure spending could move the entire chip sector. Third, the VIX. It closed Tuesday at 21.51, up nearly 40% on the day. That's not panic territory, but it's approaching the threshold where institutional investors begin forced rebalancing — which amplifies moves in both directions.
