🔥 Bitget US Stock Hotspot Sniper｜2026.08.18 Main Theme: AI Infrastructure Surges Against the Trend｜Memory · Optical Comms · Data Center Guarantees

1.Memory Chips Rally Broadly 

U.S. Commerce Secretary Lutnick stated the Trump administration does not support Apple sourcing memory from China’s CXMT and YMTC, pushing demand toward U.S. and allied suppliers. Combined with ongoing AI HBM and NAND shortages, SanDisk’s investor day guided mid-to-high teens growth and ~80% gross margins for FY28-30, driving a full-sector surge. 

🎯 Beneficiaries: SNDK, MU, WDC; Key Catalyst: Policy support plus confirmed AI demand, highest short-term elasticity.

2. Nvidia’s Multi-Billion Data Center Guarantee Lands

Nvidia confirmed a residual value guarantee of up to $105 billion for SoftBank’s SB Energy, plus a $1.5 billion equity investment, exclusively supplying Nvidia GPUs/CPUs/networking for OpenAI’s PORTS-Pike campus in Ohio (initial 4.25 GW, expandable to 8 GW), phased from 2028.

🎯 Beneficiaries: NVDA, VRT, ETN; Key Catalyst: Mega-deal locks in long-term compute demand and validates the AI factory model.

3. Optical Communications & High-Speed Interconnect Rally

Mizuho supply-chain checks show accelerating VR200 and Spectrum-X ramps, with AI rack optical modules and CPO demand exceeding expectations. Credo, Coherent, Marvell, and Lumentum all surged; the Philadelphia Semiconductor Index rose 1.64% against the broader market into a technical bull market.

🎯 Beneficiaries: CRDO, COHR, MRVL, LITE; Key Catalyst: Data-center interconnect orders materializing, capital rotating back into optical modules.

4. Anthropic Revenue Explosion Validates Demand

Bloomberg reported Anthropic’s Q2 revenue exceeded $11.5 billion (up more than 14x YoY), with annualized run-rate surpassing $65 billion and positive adjusted operating income. Rapid enterprise adoption of Claude is directly boosting upstream compute and memory demand.

 🎯 Beneficiaries: NVDA, MU, AMAT; Key Catalyst: Application-layer monetization strengthens the sustainability of infrastructure capex.

5.Applied Materials & Equipment Stocks Strengthen

Renewed AI capex expectations lifted Applied Materials more than 5%, benefiting semiconductor equipment and advanced packaging chains. The chip sector showed clear structural strength while the broader market faced pressure.

 🎯 Beneficiaries: AMAT, LRCX, KLAC; Key Catalyst: Equipment order and capacity expansion expectations heating up.

Trading Note: Broader indices remain under pressure from higher oil prices and long-end Treasury yields, but capital is clearly rotating into AI hardware (memory → optical → data centers). Structural opportunities dominate; manage position size with volume and VIX in view. U.S. equities have seen elevated volatility recently.
