A practicing semiconductor engineer's daily read on global silicon news:
AI infra capex is visibly spilling beyond GPU and HBM into networking, silicon photonics, and custom ASICs — May 12–13 data confirms it in one shot.
Chase's Take — The AI capex wave Nvidia kicked off is now flowing into the 'second ring' — networking switches, silicon photonics, custom ASICs, EDA, memory back-end. Cisco doubling its AI order guide from $5B to $9B isn't a one-company beat; it means NIC, switch, and DPU attach rates per GB200/MI400 rack are all rising together. Citi re-drawing Broadcom AI revenue from FY27 $115B to FY28 $180B says the same thing — hyperscalers are locking in ASIC+Ethernet stacks, not just GPUs. From a back-end engineer's seat, Tower Semi's $1.3B SiPho 2027 backlog matters more — first revenue proof that co-packaged optics flips from 'option' to 'required' on the next NV/AVGO ToR generation. But PHLX weakness and Qualcomm -11% say the first leg of multiple expansion is done — watch AMAT 5/14 4:30 ET print, TSMC May revenue (~5/16), NVDA/AVGO datacenter color in early June, and how long the ₩1.7T foreign sell in SK hynix runs. Korean memory consensus is finally catching up to EPS, but above ₩2M sits on yield assumptions — accept the volatility regime.
1. Cisco Reports Q3 FY26 — AI Infra Order Guide Raised $5B → $9B

TL;DR — Cisco's Q3 FY26: revenue $15.8B (+12% YoY), GAAP EPS $0.85, non-GAAP EPS $1.06. AI infrastructure orders hit $5.3B over nine months; FY26 guide raised from $5B to $9B.
