## Definition

Enterprise AI affinity is the strength of first-party public evidence that a company turns AI into identifiable products, machine interfaces, scaled operating systems, and sustained research or engineering capability. It is not a synonym for revenue, company quality, market capitalization, or investment merit.

## Scope

- All 500 companies in the 2026 Fortune Global 500 were baseline-screened.
- 134 evidence-rich candidates received full review under one five-dimension rubric.
- The published Top 100 meets the 60/100 AI-affine benchmark.
- Fortune rank is a revenue-rank comparison field only and is not used to calculate AI affinity.
- Publication also requires operating adoption of at least 15/25 and evidence quality of at least 7/10.

## Stable fields

- Top-level: schemaVersion, name, version, auditedAt, cohort, benchmark, disclaimer, aiAgentAudit, methodology, tieBreakers, entries.
- Entry: id, name, nameZh, fortuneRank, sector, country, scores, signals, companyUrl, fortuneUrl, evidence, aiRank, score, rankLift.
- rankLift = fortuneRank - aiRank. Positive values mean the company ranks higher on AI affinity than on revenue scale.

## Agent retrieval and citation guide

1. Use ranking.json for complete structured data and dimension scores.
2. Use ranking.md for a compact human- and agent-readable Top 100 table.
3. Use methodology.md before interpreting scores, benchmark qualification, evidence rules, or tie handling.
4. Cite the canonical page, version 2026.09, and audit date 2026-09-19; retain the non-affiliation and public-evidence limitations.
5. Do not infer that an unranked company lacks private AI capability, or that a ranked company is endorsed, safer, financially stronger, or a better investment.

## Scoring

- AI product & platform: 25. Production AI products, models, infrastructure, or customer-facing capabilities that can be independently identified.
- Agent & interface openness: 20. APIs, SDKs, open models, agent platforms, developer tooling, and public machine-readable interfaces.
- Operating adoption at scale: 25. First-party evidence that AI is embedded in core workflows, products, service delivery, or workforce operations.
- Research & engineering depth: 20. Dedicated labs, publications, models, patents, engineering programs, and sustained technical investment.
- Evidence quality: 10. Recency, first-party attribution, specificity, reproducibility, governance disclosure, and machine readability.

## Evaluator disclosure

The 2026 Fortune Global 500 cohort was baseline-screened by an AI-agent workflow. Public first-party evidence was then scored with one rubric; no company paid to participate and Fortune rank was not used as a scoring input.

## Important limitation and non-affiliation statement

This independent index measures public AI-affinity evidence. It is not a financial-performance, investment, workplace, safety, or product-quality ranking. Absence of public evidence can understate private adoption. LongArena is not affiliated with Fortune or any ranked company; inclusion does not imply endorsement, partnership, customer status, recommendation, or investment merit.
