The memory correction met its match on Thursday: overwhelming evidence that the demand was never in question.
US stocks rallied across the board despite another round of US strikes on Iran, with the Nasdaq Composite jumping 1.30% to 26,206.89, the S&P 500 gaining 0.81% to 7,543.64, and the Dow adding 139 points to 52,487.41. The Russell 2000 climbed more than 1%, and the Philadelphia Semiconductor Index surged nearly 5% — bouncing almost exactly off its 50-day moving average, the technical level that has contained every pullback of this cycle.
The catalysts came in rapid succession. Micron announced it will expand its US investment to more than $250 billion through 2035. SK Hynix’s Nasdaq offering drew subscriptions exceeding seven times the shares on offer. Meta launched a new AI model, confirmed plans to double its compute capacity, and directly rebutted the excess-capacity narrative that had hammered the sector a week earlier. By the close, the two-week semiconductor correction looked less like the end of a cycle and more like what it always was underneath: positioning.

Micron: A Quarter-Trillion Dollars of Conviction
Micron rose 4.38% to $990.93 — knocking once again on the $1,000 door — after announcing it will invest more than $250 billion in US manufacturing through 2035, an upward revision from its previous $200 billion commitment. The announcement came with concrete symbolism: the company poured the first concrete at its Clay, New York fab on Thursday, a facility that will become the largest semiconductor manufacturing site in US history. Two additional fabs are under construction in Boise, and Micron layered on a $3 billion strategic investment in the broader US supply-chain ecosystem.
The timing was not accidental. A week after skeptics argued that Korea’s $880 billion investment plan signaled a cycle peak, Micron answered with a quarter-trillion-dollar bet of its own — and the market read it correctly: producers do not commit decade-scale capital to a demand story they expect to fade. The stock is up nearly 250% in 2026 and has held a $1 trillion market capitalization since May.
The buying spread across the entire complex: AMD jumped 5.7%, ARM soared 9.2%, SanDisk gained 7.6%, Lam Research rose 6%, and Broadcom added 3.2%. Nvidia, unusually, sat out the rally with a 0.7% dip.
SK Hynix: Seven Times Oversubscribed
The strongest demand signal of the day came from the order book. SK Hynix’s US ADR offering — pricing at $149 per ADR to raise roughly $24.5–26.5 billion, one of the largest foreign listings in history — attracted subscriptions exceeding seven times the available shares, according to Bloomberg. The pricing came at a 3.1% premium to the Seoul close, with Bank of America, Citigroup, Goldman Sachs, and JPMorgan leading a thirteen-bank syndicate.
The oversubscription resolves the question that had haunted the memory trade for two weeks. SK Hynix’s Korean shares had fallen 30% from their late-June peak, and the bears read the decline as the smart money exiting a topping cycle. Thursday’s book told a different story: much of that selling was funds raising cash to redeploy into the ADR — a rotation within the trade, not an exit from it. With the structural seller now satisfied, the pressure that had weighed on Micron, Samsung, and SK Hynix simultaneously appears largely spent.
The ADRs begin when-issued trading Friday under the ticker SKHYV, transitioning to SKHY on July 13. Each ADR represents one-tenth of a Seoul-listed common share, and at roughly 6 times forward earnings versus Micron’s 7, the discount-repair thesis gives US investors a reason to show up.
Meta Answers Its Critics — With Products
Meta surged 4.7% in a session that functioned as a comprehensive rebuttal of the narrative that had cost it 14% the previous week.
The company launched Muse Spark 1.1, a low-cost agentic and coding model released with developer API access and public pricing for the first time — undercutting Anthropic’s top model by roughly 75% and putting Meta in direct competition with OpenAI and Anthropic in the model-serving market. Reuters separately reported that Meta will begin mass production of its in-house AI chip, code-named Iris, in September, and plans to double its compute capacity from 7 gigawatts in 2026 to 14 gigawatts in 2027, backed by long-term supply agreements for memory, flash storage, and fiber optics.
Most pointedly, Meta pushed back on the excess-capacity story directly, stating that it is not sitting on surplus compute — internal demand remains larger than supply — and that virtually no one in the industry views AI computing investment as excessive. Taken together with the $145 billion infrastructure budget, the message was unambiguous: last week’s cloud-business report described monetization strategy, not overcapacity confession.
The model-release cadence across the industry underscored the point. OpenAI rolled out its GPT-5.6 family — Sol, Terra, and Luna — across ChatGPT, Codex, and the API, alongside a new ChatGPT Work tier and desktop app. SpaceX’s xAI shipped Grok 4.5, co-developed with Cursor. Compute demand follows model releases, and the releases are accelerating.
Geopolitics: The 70–90 Oscillation
The US launched a second consecutive day of strikes on Iran, and yet oil fell — Brent dropped 2.2% to $76.30 and WTI slid 2% to $72.08. The reversal came after President Trump posted that Iran had called seeking a deal, with Qatar and Pakistan reportedly working to bring both sides back to the table.
The market’s composure has a logic to it. Iran’s Revolutionary Guard has directed its retaliation at US military bases rather than Gulf oil infrastructure — a calibrated escalation that signals Tehran wants leverage, not a supply war. The oscillation pattern is becoming familiar: crude gets bid from the low $70s as the conflict escalates, and de-escalation rhetoric tends to arrive before prices threaten $90. BCA Research’s Matt Gertken has argued that midterm politics drive the cycle — the administration needs cheap oil heading into November, making it quick to compromise when prices spike and quick to escalate when they’re low. The firm’s sobering bottom line: it still assigns a roughly 60% probability of renewed fighting after the election, and expects oil to settle in a $90–100 range rather than returning to pre-conflict levels, since nothing on the ground has fundamentally changed.
New York Fed President John Williams added a wrinkle to the macro picture, flagging AI-driven demand as his primary inflation concern and warning that a sustained demand impulse could force the Fed to raise rates. Fed funds futures now price roughly 34 basis points of hikes by year-end.
Rates: A Blowout 30-Year Auction
The bond market delivered its own vote of confidence. The Treasury’s $22 billion 30-year auction stopped through at 5.058% — 0.3 basis points below the 5.061% when-issued yield — with a bid-to-cover ratio of 2.44 versus the recent six-auction average of 2.39. Indirect bidders, the proxy for foreign demand, took down 77.7% of the offering, the second-highest share on record.
Following an equally strong 10-year auction the previous day, the message from the long end is notable: at yields above 5%, global capital is a willing buyer of US duration. Two consecutive blowout auctions suggest the rate market may be finding a ceiling — and equity investors took the hint, with rate-sensitive sectors participating fully in Thursday’s rally.
Earnings Season’s Warning Shots
Beneath the AI celebration, the consumer tape flashed caution. PepsiCo fell 3.3% despite a slight revenue beat, weighed down by declining North American food sales. Costco dropped 4.2% to a six-month low after June comparable sales decelerated. Levi’s slipped 2.3% even after beating Q2 estimates and raising both guidance and its dividend — the market fixated on Q3 revenue growth guidance of 4–5%, down from Q2’s 8%.
The pattern across all three: good results, punished stocks. It is the same dynamic Samsung encountered on Monday, now visible in consumer staples — a market priced for perfection treats deceleration as failure, even profitable deceleration.
Elsewhere, IBM lost 2.2% after reports that Starbucks plans to replace IBM software solutions with in-house AI tools — a story that hit Salesforce and ServiceNow in sympathy and crystallized the “build versus buy” anxiety hanging over enterprise software. Netflix dipped as Citi outlined four pressure points: soft viewership, M&A uncertainty, a lack of fresh growth drivers, and simple neglect as capital crowds into semiconductors. And Oracle rose despite S&P cutting its credit rating to the edge of junk territory — the AI-debt paradox in a single headline.
Bottom Line
Thursday assembled the strongest single-day case yet that the memory correction is over. The forced selling ahead of SK Hynix’s listing is complete, and the offering it fed was seven times oversubscribed. Micron answered the cycle-peak thesis with a $250 billion, decade-long commitment. Meta dismantled the excess-capacity narrative with products, production timelines, and a doubled capacity roadmap. The SOX bounced off its 50-day moving average on 5% breadth. This is what it looks like when a positioning washout ends and fundamentals reassert themselves.
The risks have not disappeared — they have relocated. Williams put AI-driven inflation on the Fed’s radar. The consumer tape is softening beneath the surface. And the same expectations problem that sank Samsung’s record quarter now awaits the hyperscalers at month-end. But for the memory trade specifically, the question that opened July — is this the top? — received its clearest answer yet: not while the order books look like this.
