After a volatile start to 2026, AI stocks are rallying again, but not in the way many expected. While companies such as Nvidia rebound on renewed investor optimism, other players may have been larger beneficiaries of the AI boom with sustained growth over the past four years, namely those focused on infrastructure, cooling, power and data. In this context,  BestBrokers is sharing its latest report on the fastest-growing companies by AI revenue and the supply chain segments driving the next phase of AI expansion.

The AI build-out has translated into rapid revenue acceleration across semiconductor designers, memory producers, hyperscale cloud platforms, and emerging infrastructure providers. To analyze these trends, the team at BestBrokers compiled and standardized AI-related revenue or the closest disclosed segment data from StockAnalysis across 20 publicly listed companies operating within the global AI supply chain. The data shows how monetisation is distributed across the ecosystem and which segments have captured the strongest growth between 2022 and 2025.

Data shows that among publicly listed companies in the AI supply chain, few have delivered gains on the scale of U.S. AI and analytics company Palantir Technologies, which has seen its stock surge 876% in just four years. Shares rose from $18.21 on 31 December 2021 to $177.75 by the end of 2025. Another standout is Vertiv Holdings, which provides high-end cooling and power systems for AI data centres. Its stock climbed 549% over the same period, rising from $24.97 to $162.01, outpacing every major player in the AI supply chain, including Nvidia (+534%), Broadcom (+420%), and Alphabet (+116%).

10 stocks gaining the most from the AI boom

Here are the 10 public companies whose stock climbed the fastest as a result of the AI boom between 2021 and 2025:

  1. Palantir Technologies: +876% from $18.21 to $177.75
  2. Vertiv Holdings: +549% from $24.97 to $162.01
  3. NVIDIA: +534% from $29.41 to $186.5
  4. Broadcom: +420% from $66.54 to $346.1
  5. SK Hynix: +397% from $86.85 to $431.6
  6. Arista Networks: +265% from $35.94 to $131.03
  7. Micron Technology: +247% from $82.27 to $285.41
  8. CrowdStrike: +129% from $204.75 to $468.76
  9. Dell Technologies: +124% from $56.17 to $125.88
  10. Alphabet: +116% from $144.85 to $313

Other highlights from the report

  • Palantir Technologies delivered the largest stock gain in the dataset, rising from $18.21 to $177.75, an 876% increase between 2022 and 2025. Once seen primarily as a niche government analytics provider, the market has re-priced it as mission-critical AI infrastructure for both government and enterprise customers.
  • The most counterintuitive result in the data belongs to Vertiv Holdings, a company that builds cooling and power management systems for data centres. Its stock rose 549% over the same period, marginally outperforming NVIDIA’s 534% gain. When every layer of the AI stack is capacity-constrained, pricing power goes to whoever controls the tightest bottleneck, and in this cycle, that bottleneck is keeping machines from overheating.
  • CoreWeave, the Nvidia-backed GPU cloud operator, has also enjoyed strong momentum following its IPO. The company’s share price rose by 93% between March and December 2025, climbing from $37.08 to $71.61 in under a year. Even more striking is the pace of its revenue growth: sales surged from just $15 million in 2022 to over $5 billion in 2025. This sharp rise reflects the rapid emergence of GPU-as-a-service infrastructure, as hyperscalers and AI labs increasingly look to outsource compute capacity amid tightening supply.
  • Not every company in the AI supply chain benefited equally. Intel’s stock fell 28%from $51.53 to $36.90 over the four years, while data centre operators Equinix and Digital Realty lost 9% (from $845.84 to $766.16) and 13% (from $176.87 to $154.71) respectively, despite the surge in AI-driven demand for compute capacity. The market is drawing a sharp line between companies directly enabling AI workloads and those serving the broader data centre market, and punishing those on the wrong side of it.
  • Memory suppliers showed strong but uneven performance. South Korea’s SK Hynix rose 397% from $86.85 to $431.60 as surging demand for high-bandwidth memory made it one of the tightest constraints in scaling large AI models, while Micron gained 247% from $82.27 to $285.41. Samsung, the world’s largest memory producer, saw its stock rise 53% from $51.90 to $79.48, a slower growth rate that reflects its sheer scale rather than any lack of positioning in the AI supply chain.
