〔Overnight Brief〕Broadcom Lifts FY26 AI Guide to $58B (+186%) and Targets $115B in 2027 on Meta 3GW and Anthropic XPU Wins — Q4 Gross Margin Drops to 73% from 78% as $1.4B Capex Bites

0. Weekly Arc

The AI capex story hardened overnight: Broadcom's CEO lifted FY2026 AI revenue guidance to $58B (+186% YoY) and said 2027 AI revenue could double to ~$115B with supply secured, while Nvidia CEO Jensen Huang used the G20 to pledge "nearly $1T" of US infrastructure spending this year and South Korea laid out a $919B sovereign AI plan ^[1][2][3][4]. Yet the same tape shows margin compression at the silicon layer — Broadcom's CFO pegged Q4 gross margin at ~73%, down from 78% YoY, with capex of $1.4B to fund the build ^[5][6]. Net: capex is broadening, custom silicon is winning the workloads, software demand is intact — but the bill lands in margin, not in orders.

1. Custom Silicon Wins — the Mechanism

• **[NEW] Broadcom CEO:** three generations of MTIA accelerators to ship to Meta through end-2027, with 3GW of Meta deployment targeted by 2028 ^[7][8]. Q4 will see mass production of Meta's custom MTIA and accelerated Ironwood deliveries to Anthropic ^[9].
• **[NEW] Broadcom CEO:** Anthropic is expected to be Broadcom's largest XPU customer in 2027, holding that position into 2028 ^[10]. (Vendor-disclosed ranking; single-source.)
• **[NEW] Broadcom CEO:** next-gen TPU 8I now in mass production for Google this quarter, with performance "on par with or better than" Nvidia's Vera Rubin ^[11]. (Vendor claim; treat as a single-source read.)
• **[ESCALATED] Nvidia CEO Jensen Huang at the G20:** "nearly $1T" of US infrastructure investment in 2026 alone, framing AI as "the great equalizer" alongside water and electricity ^[3]. The accompanying "Carolina Principles" light-regulation framework is a Trump-administration frame, not a binding commitment ^[3].
• **[NEW] Equinix + Nvidia + Together AI:** distributed inference platform "Equinix Inference Exchange" to launch Q1 2027, built on Nvidia's enterprise reference architecture and 200+ open-source models ^[12].

2. Numbers — Broadcom's Trade

• **[NEW] FY2026 AI revenue guide:** raised to $58B from $56B, +186% YoY ^[1].
• **[NEW] 2027 AI revenue target:** ~$115B, "doubling" path, supply per the CEO secured ^[2].
• **[NEW] Q4 capex:** $1.4B for semiconductor capacity ^[6][13].
• **[NEW] Q4 blended gross margin:** ~73% vs 78% YoY ^[5]. The CEO said the company still expects to hold operating margin despite the product-mix shift ^[14].
• Source check: the $1.4B capex and 73% margin figures are relayed by multiple Chinese-language wires, with the underlying earnings call as the single source ^{[14][6][13][5]}.

3. Sovereign Tailwinds and the SaaS Rebound

• **[NEW] Korea sovereign AI plan:** $919B, 8.4GW of compute by 2029, 18.4GW by 2035; SK Group committed 2GW of Nvidia Rubin systems, Naver signed 200MW ^[4]. Nvidia may already have a long-term SOCAMM deal and 2027 HBM pricing locked with SK Hynix ^[4]. (Single-source via SemiAnalysis; flag.)
• **[NEW] Berkshire's Greg Abel on Alphabet:** the ~$10B Alphabet stake, initiated ~15 months ago at a 6.5% discount, was topped up by ~$17B in Q2 to ~106M shares (~$36.6B), now the third-largest holding; Delta stake lifted 44% (+$1.6B) ^[15]. Abel called Google a "pivotal participant" in AI and framed AI data centers as an opportunity for Berkshire's energy business ^[15].
• **[NEW] Snowflake Q2 FY2027:** revenue +35% YoY to $1.55B vs ~$1.49B consensus; non-GAAP EPS $0.62 vs $0.45 consensus; non-GAAP operating margin 15.3% ^[16]. FY2027 product revenue guide raised to $6.07B (+36%), op margin guide to 14.5%; Q3 product revenue guide $1.588-1.593B vs ~$1.51B consensus ^[16].
• **[ESCALATED] "SaaS apocalypse" reversal:** Salesforce +23% in a session (largest single-day gain in six years per the source), +46% off the Feb low; Okta +29% in a day, +86% YTD; CrowdStrike +20.5% ^[17]. State Street SaaS ETF +45% from the Feb 23 trough, new all-time high, +9% YTD ^[17]. Jefferies analyst Brent Thill called it "revenge of the software nerds" ^[17].
• **[NEW] CrowdStrike-OpenAI:** expansion brings CrowdStrike enterprise security to Codex agents and OpenAI's GPT-5.6 Cyber to the Falcon platform ^[18].

4. Contrarian and Tail Risks

• The same mechanism that lifts Broadcom's revenue is compressing its gross margin: 73% Q4 vs 78% YoY ^[5]. If Q1 FY27 capex stays at or above $1.4B without an operating-margin bridge, the "we'll hold operating margin" line becomes the falsifiable claim ^[14].
• OpenAI confirmed "critical" risks for its upcoming Astra model even as it plans release — the most explicit safety caveat from the lab in the packet ^[19]. Anthropic's own IPO prospects are being framed as "huge and risky" ^[20].
• The loudest bullish datapoints are also the thinnest-sourced: Korea's $919B plan and Anthropic's largest-XPU status both lean on single sources (SemiAnalysis for HBM/SOCAMM terms, vendor commentary for customer rankings) ^[10][4]. The G20 "Carolina Principles" pitch is a US frame, not a binding commitment ^[3].
• The SaaS survivors trade is a narrow leadership list — Salesforce, Okta, CrowdStrike, Atlassian — and breadth across the wider SaaS cohort is not confirmed ^[17].
