Micron is trading near $1,096 after an 18.2% weekly surge, putting the stock up 284.3% year to date and market cap near $1.24 trillion. The company guided fiscal Q4 to roughly $50 billion in revenue, about $31.00 non-GAAP EPS, and ~86% gross margin; consensus target sits at $1,515 with three firms as high as $2,000. Shares eased about 2.2% Wednesday on profit-taking — the gross-margin guide on Sept. 30 is the number that decides the argument.
KeyBanc's Justin Patterson lifted his target to $900 from $780 and Cantor Fitzgerald's Deepak Mathivanan went to $860 from $680, both Wednesday, both keeping Overweight. Muse, launched Sept. 8, cleared 500,000 users, 250,000 daily actives and 2 million prompts in week one and hit No. 1 free app on the U.S. App Store within ten days. Cantor frames personal agents as AI's "third S-curve," sizing the market above $250 billion narrowly and past $1 trillion broadly; Meta shares are up more than 20% since launch.
The Nasdaq 100 posted a record close Tuesday, then Wednesday brought profit-taking: Nvidia fell 1.5%, Broadcom 2.6%, Micron 2.2%, while credit-sensitive hyperscalers lagged harder with Alphabet down 3.8%, Oracle 3.1% and Amazon 2.2%. The PHLX semiconductor index slipped about 1% but is still up over 14% across five sessions since the Fed cut. Concentration is the caveat — half of Tuesday's SOX gain came from just four names: MU, SNDK, AMD and NVDA.
OpenAI is in early investor-led discussions at roughly a $1.2 trillion valuation, up from $852 billion in March, per WSJ reporting. Anthropic, which closed a $65 billion Series H at a $965 billion valuation in May, is being pitched by investors toward a $2 trillion valuation at an October Nasdaq listing. Neither is public today, but combined with SpaceX these three private names carry more implied value than 45 years of U.S. IPOs — and Anthropic's debut would reprice every listed AI comp.
Palantir closed up 3.68% at $191.79, with an intraday range of $182.94 to $193.79, despite the FAA awarding its $875 million SMART air-traffic contract to Air Space Intelligence. Rosenblatt's John McPeake reiterated Buy and a $225 price target, arguing Palantir keeps a broader FAA foothold through Foundry as the agency cited integration advantages. U.S. government revenue hit $809 million last quarter, up 90% year over year.
IonQ closed at $42.54, up 4.42%, after saying it ran the industry's first real-time end-to-end quantum error decoder and announced a research-center collaboration with Nvidia. Volume hit 69.9 million shares, roughly 233% above the three-month average. Real-time decoding is the gating problem for fault-tolerant quantum, so this one matters more for the roadmap than the revenue line.
Apple touched an all-time high of $345 Tuesday before closing Wednesday at $339.75, up 0.23%, leaving it roughly 25% higher year to date. The run traces to the September event — the foldable iPhone Duo, iPhone 18 Pro, Watch Series 12 and Ultra 4, and AirPods 5. Investors are also weighing a $250 million Siri-related settlement and mixed-but-firm early iPhone 18 demand, with analysts split on whether the record streak extends.
KeyBanc's John Vinh raised Broadcom to $420 from $400, staying Overweight, citing CoWoS advanced-packaging supply revisions to 190,000 wafers next year — over 160% year-over-year growth. Barclays' Simon Coles took TSMC to $355 from $330, also Overweight. CoWoS capacity has been the physical ceiling on AI accelerator shipments, so upward revisions there read through to Nvidia, AMD and the custom-silicon complex.
Goldman Sachs pegs AI-related debt issued in 2026 at roughly $489 billion, with hyperscaler issuance projected near $420 billion next year. Oracle sold $30 billion in February after $18 billion in September 2025 and ended its fiscal year with $149 billion in long-term debt, up from $96 billion. Alphabet's $80 billion equity raise priced a day later at $84.75 billion — the largest such deal for a listed corporate — and even top-rated issuers are paying up on spread.
CoreWeave had the busiest tape among AI-infrastructure names Wednesday, pairing bullish analyst calls and new customer announcements with a large convertible debt deal. The read-through is straightforward: demand for rented AI compute is still outrunning supply. The financing structure is the thing to watch, since converts add dilution risk alongside the leverage story running through story nine.
