Revenue Segment Concentration Analyzer: How Dependent Are Big Tech Companies on a Single Business?
Analyze revenue concentration risk across Alphabet, Apple, Microsoft, Meta, Nvidia, and Palantir. See segment breakdowns, HHI concentration scores, and stress-test the impact of a top-segment revenue decline.
Primary Query
How dependent is Nvidia on data center revenue? What percentage of Apple revenue comes from iPhone? Which large-cap tech company has the most diversified revenue mix? This tool quantifies revenue concentration risk across Alphabet, Apple, Microsoft, Meta, Nvidia, and Palantir using segment-level data from SEC filings.
Tool Purpose
Revenue concentration risk — the degree to which a company depends on a single product, customer, or segment — is one of the most underanalyzed dimensions of business quality. A company generating 88% of revenue from one segment is structurally different from a company with five roughly equal revenue streams, even if their total revenues are similar.
This tool uses two lenses to measure concentration:
1. Segment share breakdown — The percentage of total revenue contributed by each reported product or geographic segment (as defined by the company in its SEC 10-K filings under ASC 280 segment reporting).
2. Herfindahl-Hirschman Index (HHI) — A standard economic measure of market concentration, applied here to revenue segments. HHI equals the sum of squared market share percentages. A single-segment company scores 10,000. An evenly split 4-segment company scores 2,500. Lower is more diversified.
$$HHI = \sum_{i=1}^{n} s_i^2$$
where $s_i$ is each segment’s share of total revenue expressed as a percentage (0–100).
A high HHI is not inherently bad — Nvidia’s Data Center concentration reflects genuine monopolistic pricing power, not business fragility. But it does mean that a demand shock in one market has an outsized impact on total revenue. The stress test built into this tool makes that quantification concrete.

Inputs
Company selector — choose from Alphabet, Apple, Microsoft, Meta, Nvidia, or Palantir.
Stress test input — enter a % revenue decline for the largest segment (default: 20%) to compute the implied total revenue impact and the resulting margin on a revised revenue base.
All segment data is pre-loaded from most recent full fiscal year SEC 10-K filings (FY2024 for all companies except Nvidia, which uses FY2025 ending January 2025).
Output
- Donut chart — segment share of total revenue with color-coded slices
- Ranked segment table — segment name, revenue ($B), share %, and growth rate YoY where available
- HHI concentration score with interpretation (diversified / moderate / concentrated / highly concentrated)
- Stress test — if top segment revenue falls by X%, total company revenue falls by Y% (computed dynamically from the segment share)
- Cross-company HHI ranking table — all 6 companies sorted from most to least concentrated
How To Use
- Select a company — the donut chart and table populate with that company’s segment breakdown
- Read the HHI score — the color-coded badge shows whether concentration is low, moderate, or high
- Adjust the stress test input — enter any % drop for the top segment to see the implied revenue impact
- Check the insight panel — it explains what the concentration level means for that specific business
- Compare across companies in the cross-company table — sort by HHI to see the full concentration spectrum
Revenue segment concentration connects directly to revenue recognition — understanding when and how each segment recognizes revenue affects both reported growth rates and the quality of earnings.

Cross-Company Concentration Ranking (HHI Score)
Ranked from most concentrated (highest HHI) to most diversified. HHI = sum of squared segment share percentages. Single-segment company = 10,000. Equally split 5-segment company = 2,000.
| Company | Top Segment | Top Seg % | Segments | HHI Score | Concentration |

Frequently Asked Questions
What is the Herfindahl-Hirschman Index (HHI) and how does it apply to revenue segments? The HHI is a standard measure of market concentration in economics, typically applied to competitor market shares in antitrust analysis. Applied to revenue segments, it measures how evenly revenue is distributed across a company’s reported business units. HHI equals the sum of squared percentage shares. A company with all revenue in one segment scores 10,000 (100² = 10,000). A company with four equal segments of 25% each scores 2,500 (4 × 25² = 2,500). Scores below 1,500 indicate meaningful diversification; scores above 5,000 indicate high dependence on a single segment.
Is revenue concentration inherently bad? No. High revenue concentration can reflect genuine competitive advantage rather than structural fragility. Nvidia’s 88% Data Center concentration is driven by near-monopoly pricing power in AI training accelerators — a demand-driven, not supply-forced, dynamic. Visa’s payments concentration reflects network effects that are nearly impossible to compete away. The risk question is: what happens if the concentrated segment faces a sudden demand shock? The stress test in this tool answers that question quantitatively for any percentage decline you choose.
Why is Meta more concentrated than Alphabet despite both being advertising businesses? Alphabet sells advertising across multiple distinct products — Search (57%), YouTube (10%), and Network (9%) — which respond differently to market conditions. Search is a pull-medium (advertisers buy intent-driven query traffic); YouTube is a push-medium (advertisers buy reach); Network reaches users on third-party websites. Meta sells advertising almost exclusively across a single ecosystem of apps (Facebook, Instagram, WhatsApp), all of which share the same underlying social graph. A single privacy regulation change (like App Tracking Transparency) hits all of Meta’s properties simultaneously in a way it would not hit Alphabet’s diverse ad inventory.
How does Apple’s iPhone concentration compare to its historical levels? iPhone was closer to 60-65% of total Apple revenue as recently as 2018. The Services segment has grown from roughly 13% in 2018 to 25% today, meaningfully reducing iPhone concentration over a six-year period. This is a deliberate strategic transition — Apple has consistently guided investors to track Services revenue growth as the indicator of its ecosystem monetization health. The trend is toward lower concentration, not higher, even as iPhone revenue has grown in absolute terms.
What does the “top segment stress test” tell an investor? The stress test answers: “If my top-risk scenario materializes — a 20% (or 30%, or 50%) decline in the dominant segment — how much does total company revenue fall?” This is a simplified first-order estimate (it assumes other segments are unchanged, which is rarely fully true) but gives a useful floor estimate for a demand shock scenario. It translates segment concentration from an abstract percentage into a concrete revenue impact, which is more useful for financial modeling.
