Weekly Market Pulse: June 15

Week in Review

It was a storybook week on Wall Street — one defined by a hawkish FOMC Wednesday that briefly rattled markets, a stunning Apple–Intel foundry deal that reshaped the semiconductor landscape, and a broad tech recovery by Thursday’s close. U.S. markets closed Friday for Juneteenth, but the four-day trading week packed enough drama to fill a month.

The FOMC held the federal funds rate at 3.50–3.75% on Wednesday — Kevin Warsh’s first meeting as Chair — with a hawkish tone that initially triggered a broad tech selloff. The S&P 500 dropped 1.21% to 7,420.10 on June 17, and the semiconductor sector lost additional ground. But the selling proved short-lived. By Thursday June 18, the S&P 500 surged 1.08% to 7,500.58 while the Nasdaq Composite jumped 1.91% to 26,517.93. For the abbreviated week, the Nasdaq gained 2.4%, while the Dow and S&P 500 each rose roughly 1% [WSJ, CNBC].

The semiconductor sector — which has now shed approximately $1.4 trillion in market value since June 1 — found a floor on Thursday led by Intel’s 11% surge on the Apple foundry deal and a broad equipment stock rally.

AI Semiconductors

NVIDIA (NVDA)

Priced a landmark $25B bond offering on June 15 — its first corporate debt sale since 2021 — across seven tranches, upsized from the initial $20B target after attracting $85B in investor orders [Reuters]. Proceeds will fund AI infrastructure investment, including data center GPU production and CoWoS capacity prepayments
Shares recovered 2.3% on Thursday as the broader tech rally lifted the entire sector, closing the week near $212
The Vera CPU narrative continues to build: reports suggest Nvidia is pitching the architecture to Chinese hyperscaler clients as a credible x86 alternative for AI inference

Broadcom (AVGO)

Concluded $2.5B in debt tender offers for six senior note series, with initial settlement on June 18 [Broadcom IR]. Stock gained 4.7% on Thursday
The FY2027 $100B AI chip revenue target remains intact, with Google/Meta TPU/IPU demand providing multi-year visibility
Shares are finding a bottom after the post-Q2 guidance selloff — the thesis shifts back to structural networking/ASIC demand

Marvell (MRVL)

Outgoing CFO Willem Meintjes filed to sell $65M in stock (211,329 shares) [The Motley Fool]. New CFO Dan Durn (ex-Adobe) will take over
Marvell recently joined the S&P 500 and remains positioned for the 800G/1.6T optical interconnect ramp — AI cluster scale-out is driving DSP and retimer demand
Shares were relatively stable for the week, closing around $310

AMD (AMD)

Fell 7.3% on Wednesday as the FOMC-driven semiconductor selloff hit hardest on names with weaker near-term guidance [MyFindEX]
The MI400 launch in 2H 2026 remains the dominant catalyst. AMD claims 320B transistors and 432GB HBM4 on the next-gen GPU
Open-source ROCm ecosystem is steadily gaining developer traction, but the Nvidia CUDA moat remains formidable

Qualcomm (QCOM)

In advanced talks to acquire AI chip startup Tenstorrent for $8-10B — a transformative deal that would give QCOM instant data center AI inference credibility [Reuters]
Stock rallied 6.17% on Thursday ahead of the June 24 Investor Day, where CEO Cristiano Amon is expected to detail the “Dragonfly” data center AI inference pivot
The Tenstorrent acquisition would bring Jim Keller’s chip architecture expertise in-house — a direct shot at Nvidia’s data center dominance

ARM Holdings (ARM)

Caught in the broad sector selloff with no ticker-specific catalyst this week
The architecture licensing super-cycle narrative — mobile → PC → data center — remains intact. Mizuho’s $500 PT (from $250) still supports the elevated valuation
Nvidia’s RTX Spark (Arm-based PC chip) and the Apple-Intel deal both validate Arm architecture’s expanding TAM

Memory & Storage

Micron (MU)

Fell 6.2% on Wednesday in the sector-wide selloff, but options implied volatility implies an 11% move for the June 24 earnings report [Trefis]
Consensus estimates: Q3 FY2026 EPS ~$19.96, driven by strong HBM3e pricing. Micron has sold out its entire 2026 HBM allocation
The SK Hynix capacity tripling announcement (June 10) continues to frame the bullish memory supercycle backdrop. The key question for MU earnings: 2027 pricing visibility

Western Digital (WDC)

Morgan Stanley raised its price target to $650 from $488 (an implied 30%+ upside), citing a global HDD shortage driven by AI data center storage demand [Invezz]
Stock surged 14–17% on Monday in the strongest single-day move among the ticker pool. JPMorgan also lifted targets
WDC has crossed 50% gross margins with 45% YoY revenue growth — the HDD business is undergoing a structural re-rating as AI training clusters require massive near-line storage

Foundry & Equipment

TSMC (TSM)

Signed a 10-year advanced packaging partnership with Amkor Technologies at its Arizona campus [Amkor IR]. The deal completes a fully domestic US chip supply chain from fabrication through packaging and testing
CoWoS capacity remains fully booked through 2027. TSMC is considering a 15% price hike for 3nm wafers in 2027 — its structural pricing power as the sole high-volume advanced node manufacturer continues to expand

Super Micro (SMCI)

Finalized its $7B equity and equity-linked financing to fund AI server orders [Yahoo Finance]. The raise includes $5B in underwritten offerings plus $2B in at-the-market equity
The company’s disclosed $39B in AI server orders continues to be the anchor narrative — but dilution concerns have pressured shares, now trading around $30.66
Stock jumped 10.37% on Thursday — the cleanest green session since the June selloff began — as investors rotated back into AI infrastructure names [TIKR]

Intel (INTC)

The week’s biggest story: Intel disclosed at the VLSI Symposium on June 16 that its next-generation 18A-P node has entered risk production, and by June 18 it was confirmed that Apple has agreed to work with Intel to design and manufacture chips in the United States [WSJ, TheStreet]
Intel surged roughly 11% on Thursday, the best single-day performance among the ticker pool
The Apple deal is a landmark foundry win — it validates Intel’s 18A process technology and positions the company as a credible TSMC alternative. Combined with Google’s “Icefish” chip talks reported earlier this month, Intel’s foundry narrative is gaining real customer momentum

ASML (ASML)

The US Commerce Secretary raised concerns that China may have obtained an ASML EUV tool despite the 2019 export ban. ASML denied shipping any EUV machine or components to China [Reuters]. Shares slipped slightly on the uncertainty
Longer-term, ASML’s raised 2026 guidance (€36-40B revenue) remains intact — high-NA EUV adoption for sub-2nm nodes is the structural demand driver

Applied Materials (AMAT), Lam Research (LRCX), KLA (KLAC)

Citi raised price targets across all three names on NAND equipment demand strength [Seeking Alpha]: AMAT target to $710 (from $550), modeling 30%/22% revenue growth YoY in CY27/28
All three equipment makers hit new all-time highs intraweek — a remarkable divergence from the broader semiconductor selloff, signaling that upstream WFE demand is secular, not cyclical
The wafer fab equipment (WFE) spending forecast of $145B+ in CY2026 continues to provide a structural floor for these names

Cloud & Hyperscaler

Google / Alphabet (GOOG)

Hyperscalers are on track for $5.3T+ in combined AI capex over the next several years [AOL]. Google separately is paying SpaceX ~$920M/month for compute capacity — a stunning figure that underscores the scale of the AI infrastructure build-out
The $80B stock sale (announced June 1) funds this trajectory, with Berkshire Hathaway contributing $10B

Microsoft (MSFT)

Microsoft has guided approximately $190B in calendar 2026 AI capex, including $25B from lease accounting [24/7 Wall St]
The aggregate hyperscaler free cash flow picture is concerning: some analysts project it could go negative by Q3 2026 as AI capex grows 70% annually vs 23% cash flow growth
Despite the capex overhang, Copilot adoption continues to mature as the enterprise AI revenue stream

Amazon (AMZN)

Cited alongside MSFT and GOOG in the “capex sustainability” debate — AWS remains the revenue anchor, but the gap between AI infrastructure spending and cash flow generation is widening
No major ticker-specific news this week, but AWS AI workload migration provides the incremental growth story

Oracle (ORCL)

The company signed $67B in AI infrastructure contracts in Q4 FY2026 (reported June 10), including $75B in total prepaid/bring-your-own-hardware AI contracts [Oracle IR]
The enormous RPO backlog ($638B) provides a multi-year revenue visibility that few other companies can match. The market’s concern remains dilution from the ~$40B FY2027 capital raise

Platform & Silicon

Meta (META)

The Muse Spark AI model API delay continues to weigh on sentiment — the company has repeatedly pushed back the release as it works through safety evaluation pipelines [Reuters]
Meta’s ad revenue engine remains robust, but the capital raise rumors that surfaced two weeks ago haven’t fully dissipated. The company is among the 4 hyperscalers in the $5.3T combined AI capex cohort

Apple (AAPL)

Two massive developments this week: (1) The Apple–Intel chip manufacturing deal, confirming Apple’s move to diversify supply away from TSMC for some chip production; (2) Apple will allow third-party AI chatbots to integrate with Siri in iOS 27 [Apple World]
The iOS 27 AI chat integration follows the WWDC 2026 Siri AI reveal — collectively, these represent Apple’s most aggressive AI platform push ever
Shares were stable for the week as the market digested the Intel foundry news and the broader AI platform strategy

The Week Ahead

Date	Event
June 22	Existing home sales (May)
June 24	Micron (MU) Q3 FY2026 earnings — the most important memory sector readout of the quarter
June 24	Qualcomm (QCOM) Investor Day — Tenstorrent acquisition details? Dragonfly AI inference roadmap?
June 25	GDP (Q1 2026 final revision)
June 26	PCE inflation data (May) — the Fed’s preferred inflation gauge

Key themes to watch: MU earnings on June 24 is the linchpin — HBM3e pricing, 2027 visibility, and memory cycle health will determine whether the memory supercycle thesis holds. QCOM’s Investor Day could be transformative if the Tenstorrent deal is formalized — it would signal Qualcomm’s ambition to become a credible data center AI player. On the macro front, May PCE data on Friday will either validate or challenge the FOMC’s hawkish posture. The Apple–Intel deal and TSMC-Amkor partnership both point to a structural re-ordering of the global semiconductor supply chain — watch for follow-on announcements at the end of the month.
