Big Tech Q1 capex hit $133B (+70% YoY) but depreciation is locked in through 2030. TSMC SoIC yields are disappointing, dragging CPO shipment forecasts lower. Turing Award winner David Patterson calls HBF the next compute bottleneck after HBM.
Big Tech spent $133B in Q1 capex, up 70% y/y. Combined depreciation hit $41.6B in the quarter. Server equipment depreciates over 5-6 years, meaning today's record spend locks in earnings drag through 2030. Consensus pegs annual depreciation for MSFT, AMZN, META, and GOOGL exceeding $430B within five years, against $372B of combined net income last year. Useful lives already extended from ~4 to 5-6 years. That lever is spent. Applied Digital signed a 15-year, 300 MW lease with a second IG hyperscaler — $7.5B in contracted value, bringing total to $23B+. Over 50% of revenue now IG-tenant backed. Initial operations mid-2027.
↳ Goldman's Covello says long hyperscalers, short semis. The thesis: if hyperscalers demonstrate positive ROI, compressed multiples re-rate while chip names have less room since capex is already priced in. Conversely, a capex slowdown crushes semis but frees hyperscaler cash flow. Alphabet's Q1 blowout — record single-day market cap gain, $4.65T total valuation approaching NVIDIA's $4.85T — gives the bull case ammunition.
Low TSMC SoIC yields are forcing the industry to lower near-term 2026 CPO shipment forecasts. Former TSMC packaging VP Douglas Yu has jumped to MediaTek, where insiders expect his arrival to materially de-risk their first EMIB-T adoption. The reporting outlet cited an industry source: "TSMC assumed customers would not leave, but they did." TSMC is now rushing to fill the packaging gap between CoWoS and alternatives. Meanwhile, Apple's Q2 FY26 call confirms SoC and leading-edge node capacity — not memory — is the true unit shipment constraint. Apple can secure enough memory but can't get sufficient TSMC leading-edge supply. Mac mini and Mac lines are allocation-limited.
↳ TSMC's structural edge: fabs break even at 25% utilization (down from 35-40%) as revenue outpaces capex. But packaging bottlenecks are opening doors for competitors. MediaTek is the clear beneficiary — GS sees 90% upside on TP5000, with next-gen AI ASIC ASPs "multiple times higher" as the company moves into compute die design beyond I/O dies. GM-accretive.
Turing Award winner and RISC architect David Patterson flags High Bandwidth Flash (HBF) as the likely next bottleneck after HBM, calling demand surge "highly likely." He is actively collaborating with semiconductor companies on it. Epi wafer supply-demand is tightening faster than expected. Models show leading-edge logic (≤7nm) wafer demand inflecting next year, reaching ~1M wpm by CY28 (~10% of total 300mm equivalent). Wafer makers GlobalWafers, SUMCO, Shin-Etsu, and Siltronics stand to benefit. Korea April semiconductor exports confirm the acceleration: DRAM $9.25B (+83% QoQ), SSD $3.84B (+181% QoQ). But here's the nuance: commodity memory profitability now exceeds HBM, giving the Memory Big 3 stronger incentive to prioritize commodity DRAM/NAND over HBM shipments in the near term.
↳ This sets up a potential HBM allocation squeeze in 2H26 even as AI demand accelerates. The shipment mix shift could catch forecasters offside.
Huawei AI chip revenue projected at ~$12B in 2026, up from $7.5B in 2025 (+60%). Majority of orders are 950PR chips (mass production since March); 950DT upgrade planned for Q4. Beijing directing tech firms to support domestic producers and limit NVIDIA chips to domestic use only. NVIDIA H200 reportedly unable to clear China customs. Morgan Stanley sees China AI chip market at $67B by 2030, with 86% from domestic suppliers (~$21B this year). SMIC has reportedly produced early 3nm test wafers.
Top AMD bare-metal providers (Vultr, DO, TW) are sold out on MI355x. One provider raising prices on 8x bare metal boxes — "zero availability." DO pricing H100s at $3.39 and MI300x at $1.99 (~70% discount to NVIDIA). Most competitors not even offering short-term contracts. Vultr moved a massive number of MI355x units.
MPWR: AI demand broadening beyond GPUs into CPU servers, optical modules, switches, storage, DDR5, and higher-voltage power conversion. Aixtron: Q1 €59M revenue, €171M orders. Optoelectronics TAM sized at 80-100 G10 tools/year (€300-400M annual). Multi-tool orders from customers accelerating. AXT: indium phosphide demand outpacing qualified supply; customers shifting to multi-year allocations; China AI optical ecosystem scaling rapidly. Cohu: Eclipse handler targeting AI accelerator thermal management and HBM inspection — revenue mix shifting meaningfully. Teradyne: beat Q1 ($1.28B revenue, 60.9% GM) but guided Q2 midpoint down 6% QoQ. Entering transition period 2H26.
GPT-5.5 reportedly "completely reversed" the competitive landscape. Opus 4.7 underwhelms vs. 4.6 — longer context success rates dropping. Root cause per sources: Anthropic compute shortage vs. OpenAI compute lead. OpenAI reportedly cracked recursive self-improvement for Codex. UK AISI cyber eval shows GPT-5.5 performing similarly to Mythos on long-horizon agentic tasks. $TEAM +20% after hours — potential software narrative inflection.
