Two Mystery Clients Account for 39% of Nvidia’s Revenue in Q2 2025: A Deep Dive into Concentration Risks
Nvidia, the global leader in graphics processing units (GPUs) for artificial intelligence (AI) and data centers, reported that two undisclosed direct customers, referred to as “Customer A” and “Customer B,” accounted for 39% of its fiscal Q2 2025 revenue (ended July 28, 2025). This significant concentration, with Customer A contributing 23% and Customer B 16% of the $46.7 billion total revenue, has sparked concerns about the company’s reliance on a narrow client base. As Nvidia’s growth is fueled by the AI boom, this development underscores potential vulnerabilities and opportunities in its business model, particularly within the data center segment, which drives 88% of its revenue.
Latest Updates
In its Q2 2025 financial filing with the Securities and Exchange Commission, Nvidia disclosed that these two mystery clients significantly increased their share of revenue compared to the previous year, when the top two customers contributed 14% and 11%. The company’s data center segment, powered by high-demand GPUs like the H200 and upcoming Blackwell architecture, generated $41.1 billion, though it slightly missed analyst estimates. Nvidia’s CEO, Jensen Huang, emphasized robust demand from cloud providers, enterprises, and emerging “neoclouds” tailored for AI services. However, the lack of transparency regarding the identities of Customer A and Customer B has fueled speculation, with analysts pointing to tech giants like Microsoft, Amazon, Alphabet, Meta, or Tesla as likely candidates due to their massive AI infrastructure investments. Additionally, an unnamed AI research and development company was noted as a significant contributor through both direct and indirect channels, adding to the intrigue.
Key highlights:
- Total Q2 revenue reached $46.7 billion, up 56% year-over-year, driven by AI data center demand.
- Customer concentration rose from 25% (two clients) in Q2 2024 to 39% in Q2 2025.
- Cloud providers account for roughly 50% of Nvidia’s data center revenue, with indirect customers (via direct clients) also exceeding 10% of total revenue each.

| Customer B Contribution | 16% of total revenue (~$7.47 billion) |
| Combined Top Client Share | 39% of total revenue (~$18.22 billion) |
| Other Key Contributors | Two indirect customers (via A and B) each >10%; one AI R&D company |
| Customer Type | Direct customers (e.g., OEMs, system integrators like Dell, Foxconn) |
| Primary Revenue Driver | AI data center GPUs (H200, upcoming Blackwell GB200) |
*Note: Exact identities of Customer A and B remain undisclosed; figures are approximate based on reported percentages.
Past History of Nvidia’s Client Concentration
Nvidia’s revenue concentration has been a recurring theme as the AI boom accelerated since 2023. In fiscal 2024, one customer (believed to be Microsoft) accounted for 19% of revenue, with other tech giants like Meta (13%) and Amazon (6%) also significant, according to supply chain estimates. In Q1 2025, two direct customers represented 24% of revenue (13% and 11%), showing a gradual increase in dependency. Historically, Nvidia’s growth was more diversified, with gaming and automotive segments balancing data center reliance. The generative AI surge, starting in mid-2023, shifted focus to data centers, with four customers accounting for 46% of Q2 2024 revenue. This trend reflects the massive capital expenditures (capex) by tech giants—Microsoft ($55.7 billion in fiscal 2024), Amazon ($60 billion in 2024), and Meta ($40 billion in 2024)—for AI infrastructure, often centered on Nvidia’s GPUs.
Future Scopes and Outlook
Nvidia projects a $3-4 trillion AI infrastructure market by 2030, with its Blackwell GPUs (like GB200, costing over $80,000 each) expected to drive billions in Q4 2025 revenue. However, the 39% concentration raises risks: if either Customer A or B reduces spending, revenue could take a hit. Analysts highlight that competitors like AMD (launching new AI chips in H2 2025) and in-house chips from Microsoft, Amazon, and Alphabet could erode Nvidia’s dominance long-term. Still, short-term demand remains strong, with Morgan Stanley estimating $300 billion in 2025 AI capex from major tech firms. Diversifying its client base, including enterprises and foreign governments, could mitigate risks. Posts on X suggest sentiment is mixed, with some viewing concentration as a supply-side strength (Nvidia prioritizing large buyers) and others as a vulnerability if demand softens.
Nvidia’s Revenue Dynamics and AI Market Opportunities
The revelation that two mystery clients account for 39% of Nvidia’s Q2 2025 revenue highlights both its dominance in AI infrastructure and the risks of customer concentration. Investors and businesses should monitor capex trends among tech giants and Nvidia’s efforts to diversify, staying attuned to themes like Nvidia revenue, mystery clients, AI infrastructure, and customer concentration for strategic decision-making in the evolving AI market.
