### Nvidia: GPU Computing Dominance
Nvidia remains the primary supplier of AI computing hardware. Its next-generation Blackwell systems are now entering production ramps, while the CUDA software platform continues to lock in developers across the industry. Nvidia has expanded beyond just selling chips to offering complete AI systems.
Additionally, Nvidia’s Ethernet products for AI networking extend the company’s reach beyond GPUs. As AI training workloads shift toward massive multi-node clusters and inference scales at edge locations, Nvidia’s technology remains at the core. Analysts currently assign Nvidia 43 buy ratings, 2 holds, and 1 sell. Despite some supply chain volatility potentially influencing pricing, GPUs power the majority of AI model development roadmaps in production today.

### Microsoft: Cloud and Software Integration
Microsoft captures revenue from multiple AI deployment points. The Azure cloud platform provides essential infrastructure hosting for AI workloads, while Microsoft’s strategic partnership with OpenAI delivers enterprise customers direct access to powerful models.
Microsoft’s Copilot products are integrated across Microsoft 365, GitHub, and security tools, converting user interest into steady per-seat subscription revenue. Hyperscaler AI workloads continue driving strong growth in Azure, supported by elevated capital expenditures for data center expansion. The company benefits from a self-reinforcing cycle of usage leading to increased spending across its product suite.
Analysts currently rate Microsoft with 37 buy recommendations, 1 hold, and no sells.

### Broadcom: Networking Silicon and Custom Accelerators
Broadcom supplies the switch silicon that connects AI cluster nodes, with its Tomahawk and Jericho products managing crucial data fabric requirements. The company also designs custom accelerators for hyperscale cloud providers, augmenting its AI-focused portfolio.
Broadcom’s acquisition of VMware provides robust cash flow to fund ongoing research and development. Though customer concentration presents some risk, revenue from AI-related products continues to grow, with production deployments expanding beyond initial pilot projects.
Broadcom is rated with 30 buys, 1 hold, and no sells by analysts.
