Summary of J.P. Morgan's Cloud Capex Outlook Industry Overview - The report focuses on the **Cloud Capital Expenditures (Capex)** outlook for the **datacenter** sector, particularly among the **Top 4 U.S. Cloud Service Providers (CSPs)**, which include Meta, Google, Amazon, and Microsoft [1][3][8]. Key Points and Arguments 1. **Capex Growth for 2025**: - Datacenter capex growth is now projected to be nearly **+60% year-over-year (y/y)** in 2025, up from a previous forecast of **+40%** [1][3][8]. - This growth translates to an increase of over **$100 billion** in 2025, marking the largest annual increase to date, surpassing the previous record set in 2024 [1][3][8]. 2. **Capex Growth for 2026**: - For 2026, growth expectations have been revised to **+30% y/y**, representing an increase of more than **$80 billion** [1][3][8]. 3. **Investment Drivers**: - The surge in capex is primarily driven by investments in **AI** and related infrastructure, with robust double-digit growth across all U.S. hyperscalers [1][3][8]. - Additionally, investments from **Tier 2 CSPs** and **neoclouds** are expected to grow significantly, with estimates suggesting a rise to nearly **$80 billion** in 2026, up from less than **$60 billion** in 2025 [1][3][8]. 4. **Equipment Categories**: - While high-cost **servers** with advanced **XPUs** will dominate the expansion, there is also a notable increase in spending on **networking equipment** such as datacenter switches, optical transceivers, and DCI solutions [1][3][8]. 5. **Company Coverage**: - J.P. Morgan remains optimistic about companies that support AI infrastructure demands, particularly in networking. Companies highlighted include **Arista (ANET)**, **Celestica (CLS)**, **Ciena (CIEN)**, **Coherent (COHR)**, **Lumentum (LITE)**, and **Fabrinet (FN)**, all rated as **Overweight (OW)** [1][3][8]. Additional Important Insights - The report indicates that the **datacenter capex** from a sample of public Tier 2 U.S. CSPs and emerging neoclouds is expected to grow over **+100% y/y** in 2025, surpassing the average spend from the Top 4 CSPs prior to 2023 [4][34]. - The anticipated growth for Tier 2 and neoclouds in 2026 is projected at **+35% y/y**, again outpacing the Top 4 CSPs [4][34]. - The report emphasizes that the sample excludes many private companies, which are also expected to show robust spending intentions for 2025 and beyond [4][34]. This summary encapsulates the critical insights from the J.P. Morgan report on the cloud capex outlook, highlighting significant growth trends and investment opportunities within the datacenter sector.
