AWS's custom chips, including Trainium for AI training and Inferentia for inference, offer superior price-performance compared to many alternatives. Trainium2, a multibillion-dollar business with 150% quarter-over-quarter revenue growth in Q3, is fully subscribed. Amazon's Project Rainier has built a large AI compute cluster with approximately 500,000 Trainium2 chips, expected to expand to 1 million by year-end, supporting AI models like Anthropic's Claude. The upcoming Trainium3 chip preview is slated for late 2025, with volume availability in early 2026, promising 40% better price-performance than Trainium2. AWS also offers customers chip options from Nvidia, AMD, and Intel, reducing vendor lock-in risks. Beyond hardware, AWS provides AI platform services such as SageMaker for custom foundational model development and Bedrock for access to various foundational models. AWS's model-agnostic approach and focus on price-performance aim to broaden its enterprise customer base. Additionally, AWS is advancing agentic AI with open-source tools like Strands and infrastructure components like AgentCore, enabling secure and scalable deployment of AI agents. Demonstrations include Kiro, an agentic coding IDE, and the Transform agent, showcasing real-time enterprise utility. While Microsoft and Alphabet are growing faster in AI cloud revenue, AWS's rapid capacity expansion, custom silicon innovation, and comprehensive AI stack position it as a significant contender in the 2025 AI cloud race.

Nvidia's Dominance and Strategic Partnerships in AI Hardware

Nvidia continues to solidify its leadership in AI computing hardware, driven by strong demand for its advanced graphics processing units (GPUs). At its 2025 GTC conference, CEO Jensen Huang announced $500 billion in orders for 20 million Blackwell and Rubin GPUs through 2026, with six million units already shipped. This backlog translates to approximately $70 billion in revenue per quarter over the next five quarters from these GPUs alone. Nvidia's second-quarter fiscal 2026 revenue was $47 billion, underscoring the scale of its business. Despite U.S. export restrictions preventing Nvidia from selling to the Chinese data center market, which previously accounted for 20% to 25% of its data center revenue, the company continues to thrive. There remains potential for future deals to allow some GPU sales in China. Nvidia is partnering with the U.S. Department of Energy and Oracle to build seven AI supercomputers, including the Solstice system with 100,000 Blackwell GPUs and the Equinox system with 10,000 GPUs. These supercomputers will support thousands of researchers in developing AI reasoning models and agentic AI workflows, reinforcing Nvidia's dominant position in AI infrastructure. Nvidia's GPUs remain the industry standard for AI workloads, favored for their power and flexibility. The company has maintained over 50% year-over-year revenue growth for nine consecutive quarters, with nearly 90% of revenue derived from data centers. While Nvidia faces competition from companies like AMD and Broadcom, its ecosystem and product performance continue to attract hyperscalers and AI developers. Nvidia's valuation, trading at approximately 55 times trailing sales, reflects high growth expectations, supported by its substantial order backlog and strategic partnerships.

CoreWeave's Rapid Growth and Challenges in AI Cloud Infrastructure

CoreWeave, a cloud computing company specializing in AI infrastructure, has experienced exceptional revenue growth, with a 134% year-over-year increase in Q3 2025 to $1.36 billion and a 205% growth in the first nine months of 2025 to $3.6 billion. The company focuses on providing AI-first data centers powered primarily by Nvidia GPUs, catering to the growing demand for AI compute capacity. CoreWeave has secured major clients, including Meta Platforms, with a $14 billion deal, and Microsoft, which uses CoreWeave's specialized infrastructure despite being a cloud provider itself. The company's revenue backlog surged 271% year-over-year to $55.6 billion in Q3, with 40% expected to be recognized within two years and an additional 39% within 25 to 48 months, indicating strong future revenue visibility. CoreWeave's active data center power capacity increased to 590 megawatts across 41 data centers in Q3, up from 470 megawatts in 33 data centers in Q2. Contracted data center power capacity rose to 2.9 gigawatts from 2.2 gigawatts in the prior quarter, with management estimating the ability to bring over 1 gigawatt online within 12 to 24 months. Despite this growth, CoreWeave faces challenges related to profitability and capital expenditures. The company incurred net losses of $771 million in the first nine months of 2025, with total debt exceeding $14 billion, significantly higher than the prior year. The short lifespan of GPUs used for AI workloads, estimated at one to three years, necessitates continuous capital investment to maintain cutting-edge infrastructure. CoreWeave's recent revenue guidance was lowered due to delays from a third-party data center developer, though the affected customer has agreed to adjust delivery schedules without impacting contract value. The company is witnessing relentless demand for AI compute capacity amid stretched supply chains. While CoreWeave's growth prospects are strong, its path to sustained profitability remains uncertain, with significant capital spending required to support expansion. Investors view CoreWeave as a potential multibagger if it can achieve profitability while maintaining its rapid growth trajectory.
