AI Market Leaders: How Equity Performance Is Evolving among AI Innovators

Key Takeaways

  • Semiconductor leaders like Nvidia, Micron and Taiwan Semiconductor have been the cornerstone of Artificial Intelligence's (AI) rapid development, fueled by high-demand chips enabling advanced AI applications.
  • As hyperscalers ramp up AI infrastructure investments, networking companies such as Credo Technology and Broadcom have delivered standout earnings, driven by essential high-speed connectivity solutions.
  • With AI’s scope expanding, firms across diverse sectors—including quantum computing, AI-driven drug discovery and enterprise software—are capturing investor attention, signaling an evolving market landscape.

Semiconductors as AI’s Backbone

The AI market has evolved significantly in the past two years, shifting from a heavy reliance on mega-cap and semiconductor dominance to a more diverse set of beneficiaries. The launch of ChatGPT was a landmark moment for AI and a wake-up call for the market. Semiconductors,1 particularly Nvidia, took center stage with its graphics processing units (GPUs), driving a 53% gain in the space over the following 18 months—outperforming the S&P 500 Index by more than 20% for the period. Key players like Micron and SK Hynix played important roles with high-bandwidth memory (HBM) chips, while Taiwan Semiconductor booked its advanced chip manufacturing pipeline well into the future. This semiconductor hardware enabled AI’s early growth, solidifying semiconductors as the foundation of the AI revolution.

Other firms offering AI solutions—spanning software, robotics, autonomous vehicles and other AI applications—failed to catch the initial wave that benefited semiconductor stocks. Hyperscalers such as Amazon, Microsoft, Alphabet and Meta are leading the AI data center buildout, buying Nvidia’s chips and other semiconductor equipment to create what Nvidia CEO Jensen Huang calls “AI factories.” This infrastructure development is ongoing, with hyperscalers investing more than $200 billion in capex in 2024 and planning an additional $300 billion in 2025. As these AI factories come online, the foundation for AI will be set, and value creation could extend further across the entire AI ecosystem.
