TAIEX fell 76 points to 43,149 on NT$1.26T turnover after a 1,450-point intraday swing, driven by hot US May CPI (4.2% YoY) and renewed US-Iran tensions; foreigners net sold NT$35.8B while domestic investment trusts bought NT$12.8B for a 10th straight session. Listed-co May revenue hit a record (+34% YoY) and Q2 profit could reach NT$1.6T; TSMC (2330) closed flat at NT$2,250 with 2026 EPS seen at NT$125, Hon Hai (2317) -1.71% on Vera Rubin NVL72/liquid-cooling showcase, and MediaTek (2454) -1.68% as a potential 2nm supplier for Google TPU v9.

Why it matters: Daily market wrap with sector commentary and named AI supply-chain updates (TSMC May revenue record, Hon Hai Vera Rubin NVL72, MediaTek TPU v9 2nm prospect), but no single stock-moving catalyst — fits a sector/supply-chain story rather than a discrete event.

SEMI's WWSEMS report shows Q1 2026 global semiconductor equipment sales reached a record $36.55B, up 14% YoY and 1% QoQ, driven by AI-related capex in advanced logic, DRAM, and advanced packaging. The sustained equipment cycle supports order books at major front-end and back-end tool suppliers and signals continued fab capex strength benefiting foundry and memory leaders.

Why it matters: Sector-level market data point confirming strong equipment cycle, supportive backdrop for foundry/memory/equipment names but not a single-stock catalyst.

Taiwan's May machinery exports jumped to a record $3.50B, breaking the July 2022 high of $3.38B, with electronics equipment exports topping $719M (+44.7% YTD) on AI server and semiconductor capex demand. Machinery imports also surged 25% YoY to $6.85B in May as domestic fab buildouts accelerate, though the trade group flagged FX disadvantage vs. JPY (-55.5%) and KRW (-43.5%) since 2021 as a competitive headwind.

Why it matters: Sector-level trade data confirming Taiwan semi/AI equipment supply-chain momentum, but no named company catalyst or specific contract — informational rather than directly stock-moving.

Gigabyte's (2376-TW) server arm Giga Computing said it will integrate Broadcom's (AVGO) advanced storage interface cards across its full server line-up to accelerate AI inference workloads from data center to edge. Management is targeting double-digit annual growth in global cloud infrastructure demand and a 10-15% lift in product gross margin from the expanded partnership.

Why it matters: Supply-chain/product roadmap story with a margin target but no booked contract value or capex; positive read-through for Gigabyte server mix but not a discrete stock-moving event.

Counterpoint reports global smartphone AP-SoC shipments declined 8% YoY in Q1 2026, with MediaTek (32%), Qualcomm (23%), Apple (19%), UNISOC (14%), Samsung LSI (7%) and HiSilicon (4%) rounding out the leaderboard. MediaTek and Qualcomm both saw YoY shipment declines tied to persistent memory shortages and Galaxy S26 launch delays plus Exynos 2600 in-sourcing by Samsung, while Apple gained share on iPhone 17/17e strength.

Why it matters: Sector market-share data point with read-throughs to MediaTek share leadership and Samsung System LSI Exynos 2600 in-sourcing, but no single stock-moving catalyst.

SK Hynix will start mass production of 375-layer 3D NAND at its Cheongju M15 fab by end-2026, replacing tungsten with molybdenum in word lines to overcome resistance limits in ultra-high stacks. TEL won the deposition tool order over Lam Research, with Air Liquide, Entegris and Merck as key material suppliers; Samsung is pursuing a 400-layer+ Gen10 NAND in H2 and ramping Mo usage from 4 to 10 tons this year, potentially 80 tons by 2030.

Why it matters: Confirmed mass-production timeline and named supplier selections (TEL win, Lam loss, Air Liquide/Entegris/Merck) plus Samsung's parallel roadmap make this directly stock-moving for Korean memory and global equipment names.

SK Group Chairman Chey Tae-won told Nikkei that SK Hynix will double wafer capacity within five years and triple it by 2034 to meet AI memory demand, pulling the Yongin mega-fab cluster timeline forward by roughly 10 years from 2045. Chey flagged Japan as a leading candidate for the next overseas fab once Korean buildout is complete, citing its mature semi ecosystem; he also called the recent surge past $1T market cap (third after TSMC and Samsung) an overreaction in a volatile market.

Why it matters: Chairman-level capex guidance — tripling wafer capacity by 2034 and pulling Yongin completion forward ~10 years — is a material long-dated capex signal for SK Hynix, Samsung, and the entire KR/TW semi equipment & materials supply chain.

ITE Tech (3014-TW) said its Embedded Controller and HDMI 2.1 Retimer have secured the majority of design wins on a US Agentic AI compute platform — widely speculated to be Nvidia's RTX Spark, co-developed with MediaTek (2454-TW) and Microsoft — with mass production targeted as early as 2H. ITE already holds >45% global share in notebook EC chips, and the win reinforces its position as AI PCs ramp across X86 and ARM designs.

Why it matters: Design-win supply-chain story with mass production still pending and the Nvidia platform link based on market speculation rather than confirmation; MediaTek exposure is incidental.

Republican members of Congress sent a letter to ITC Chair Amy Karpel urging strict enforcement of US patent law against TSMC, arguing its strategic role in US semiconductors shouldn't shield it from an import ban if infringement is found. The ITC probe stems from a complaint by Longitude Licensing and Marlin Semiconductor (which acquired patents from UMC in 2021) targeting TSMC's advanced nodes used for AI accelerators and HPC chips; Apple and Broadcom were also named, but TSMC remains the focal point.

Why it matters: A US ITC patent probe with a potential import ban is a real overhang for TSMC and downstream AI/HPC customers, but it's still at the political-letter stage with no ruling or quantified impact yet.
