Report Summary
Cross-provider service equivalence with category leadership indicators. Compute, storage, database, and AI/model API services are shown with each provider's equivalent offering. The ★ marker indicates the category leader based on adoption signal, analyst consensus, and revenue disclosure. After H1 2026 earnings, AWS Bedrock has crystallized as the model-agnostic distribution layer — Anthropic exclusive ($100B/5GW), OpenAI Frontier exclusive third-party ($100B/8yr, Jul 31, 2026), plus Llama, Cohere, Mistral. Foundation model API is now firmly AWS-led on enterprise adoption despite a still-strong developer preference for OpenAI direct.

2. Category Leadership · Detailed
Where each provider leads and why. Based on adoption data, revenue disclosure, and analyst consensus. Not per-service revenue (which providers don't publish).
Foundation model API
AWS · BedrockNow the model-agnostic distribution layer. As of Jul 31, 2026: Anthropic exclusive ($100B/5GW), OpenAI exclusive third-party distribution for Frontier ($100B/8yr, $50B Amazon investment complete), plus Llama, Cohere, Mistral. Used by ~80% of Fortune 100. Combined AWS-locked model contracts now exceed $200B. Caveat: only 4.3% of YC '24 cohort uses Bedrock vs 88% for OpenAI direct — enterprise vs. developer split remains sharp.
Enterprise agent platform
Azure · Agent 365GA May 1, 2026. Bundled into M365 E7 ($15/user/mo standalone). Copilot base of 30M paid seats (up from 20M in Q3 FY26) is the distribution wedge — Microsoft can push agents into every M365 tenant. Registry Sync connects AWS Bedrock + Google Cloud agents under Microsoft's governance plane (preview).
Data warehouse
GCP · BigQueryServerless-native from day one. Cross-Cloud Lakehouse extension (Iceberg-native BigLake) lets Gemini agents read AWS S3 + Azure Blob + GCS without data copies — announced Cloud Next 2026. BigQuery ML adoption drives Vertex AI stickiness.
Autonomous / self-managed database
OCI · Autonomous DatabaseMulticloud AI Database grew +404% YoY in Q4 FY26 — Oracle's fastest-growing business ever. Oracle Database@AWS / @Azure / @GCP means enterprises can stay on their primary hyperscaler and add OCI DB. Wedge strategy is working.
Object storage
AWS · S3Default reference. Cross-cloud data lakes are still S3-anchored 60%+ of the time per Datadog telemetry. S3 Vectors GA'd in Q1 2026 for RAG workloads.
Custom AI silicon
AWS · TrainiumAnthropic locked to 5GW. OpenAI committed to 2GW as of Jul 31. $25B+ Trainium run rate. Google's TPUs (Ironwood/Trillium) remain the closest competitor and dominate Google-internal workloads (Search, Gemini).
Identity / IAM
Azure · Entra IDRebrand of Azure AD. Deeply embedded in M365 tenants — the identity pane most enterprise apps federate through. Cross-cloud SSO into AWS/GCP is typically anchored on Entra even for AWS-primary shops.
Container orchestration
GCP · GKEGKE Autopilot is the reference cloud-managed K8s experience. Google invented Kubernetes; GKE compatibility is the gold standard other providers benchmark against. Anthos extends GKE to on-prem and other clouds.
Contact center
AWS · ConnectConnect split into 4 agentic products at re:Invent 2026: Customer, Talent, Decisions, Health. Existing Connect base of ~100K contact centers with millions of agents provides distribution moat.
3. Adoption Signals from H1 2026 Earnings
Quantitative signals about specific services or product lines disclosed on earnings calls.
| Provider | Service / Product | Signal & Context | Metric |
|---|---|---|---|
| AWS | Trainium | Model contracts locked: Anthropic $100B/5GW + OpenAI $100B/2GW + others. Q2 CY26 was fastest AWS growth in 18 quarters (+37%). | $200B+ locked |
| AWS | AI + Chips business | Both AI and Chips businesses cleared $25B+ annualized run rates in Q2 CY26 with triple-digit growth. Disclosed on call. | $25B+ each |
| Azure | Copilot (M365) | 30M paid seats reported on FY26 Q4 call (from 20M in Q3). +50% QoQ growth. Distribution wedge for Agent 365. | 30M seats |
| Azure | Azure AI run rate | Crossed $45B in Q4 FY26 (from $37B in Q3). AI drove ~10-11 pp of Azure's 43% growth. | $45B run rate |
| GCP | Gemini App | 950M MAU as of Q2 CY26. Daily active users tripled YoY. Consumer AI at scale. | 950M MAU |
| GCP | Model APIs (Gemini) | 22B tokens/minute across Google models (up from 16B/min in Q1). 9M+ developers building with Google models monthly. | 22B tok/min |
| OCI | Multicloud AI Database | Oracle DB on AWS/Azure/GCP. Grew +404% YoY in Q4 FY26 — called "fastest growing business ever" on the call. | +404% YoY |
| OCI | GPU infrastructure | 97.5% global GPU utilization — supply is the constraint. $67B AI infrastructure contracts signed in Q4 FY26 alone. | 97.5% util |

Important: ★ markers denote category leadership by adoption signal and analyst consensus, NOT by per-service revenue (which providers don't disclose). Treat as directional, not definitive. Refresh cadence: Quarterly post-earnings, plus Cloud Next ('26 in April), AWS re:Invent (Dec), Microsoft Ignite (Nov), and Oracle CloudWorld (Sep).
