Compare moats
Up to three covered companies, band by band. Every call is a curated editorial judgment, never a disclosed figure — and every band carries its cited basis.
| Digital Realty Trust | C3.ai | |
|---|---|---|
| Moat rating | narrow The FY2025 10-K's own competitive record cuts both ways. Item 1 says a "high-quality, highly interconnected global portfolio such as ours could not be easily replicated today on a cost-competitive basis," yet Item 1A concedes that competitors have "significantly greater financial, marketing and other resources and more ready access to capital" and that as rivals keep developing space, "rental rates may be reduced or we may face delays in leasing." A durable advantage that its own filing says new supply can price against is bounded, not unassailable. | eroding The FY2026 10-K's own financial statements show revenue down ~36% year over year to $250.3M with GAAP gross profit collapsing from $235.9M to $77.4M, while its Competition section concedes the primary competition is do-it-yourself platforms assembled from hyperscaler and open-source components and that strategic partners may offer substantially similar solutions — differentiation that is visibly failing to defend share or price in a growing enterprise-AI market. |
| Moat type | network effects Item 1 attributes the hard-to-replicate part of the portfolio to connectivity rather than to real estate: "the network density, interconnection infrastructure and connectivity-centric customers in certain of our data centers have led to the organic formation of densely connected data communities that are difficult for competitors to replicate." That community sits on over 232,000 cross connects in over 55 metros, so each network and cloud that lands makes the same building worth more to the next tenant. | intangibles ip The 10-K's 'Strategic Competitive IP Advantage' section grounds the remaining moat in patents — 33 issued U.S. patents including a foundational agentic-AI orchestration patent (US 12,111,859) — and the patented model-driven architecture the filing presents as its sustainable competitive advantage. |
| Leadership | co leader Item 1 claims the title of "the largest global provider of cloud- and carrier-neutral data center, colocation and interconnection solutions," but the Competition section names Equinix and NTT as operators of properties "similar to ours in some of the same metropolitan areas," plus Global Switch and regional operators abroad — a shared top tier on the company's own telling, not a solitary one. | behind Despite tracker recognitions the filing cites (a Leader in the 2024 Forrester Wave for AI/ML Platforms; 2024-2025 Constellation ShortLists), FY2026 revenue contracted ~36% while the filing describes the AI software market as expanding past $450B — a franchise losing ground to the DIY and hyperscaler alternatives its own Competition section names. |
| Pricing power | strong FY2025 renewals signed re-priced upward in every bucket — +27.0% on greater-than-1 MW space ($146 to $186 per square foot), +4.6% on 0-1 MW ($268 to $280) and +43.0% on other ($49 to $71) — and MD&A expects average aggregate rental rates on 2026 renewals to be positive against the rates currently paid for the same space "on a GAAP basis and on a cash basis." On costs, the filing says utilities expense "is our largest expense category" and that "the vast majority of the expense is passed directly through to our customers," which it credits with significantly mitigating exposure to power-cost increases rather than removing it. The cap: Item 1A warns competitor development could still force rates down. | weak GAAP gross margin fell from ~61% in FY2025 to ~31% in FY2026 per the 10-K income statement, and the filing describes its consumption-based pricing model as adopted to make products 'easier and less costly' to adopt — the opposite of pricing leverage. |
| Summary | Digital Realty rents space, power and connectivity rather than compute: at 2025 year-end its portfolio held 310 data centers and roughly 57.6 million rentable square feet across more than 55 metros in over 30 countries, about 84.7% leased, serving more than 5,000 customers. Two different businesses sit inside that footprint. The greater-than-1 MW wholesale side is a capital-and-power race — 769 MW of projects underway with 64% pre-leased, and land that "could accommodate over 3,500 megawatts of additional data center capacity" — where the 10-K names Equinix, NTT, Global Switch and "various private operators" as rivals and warns that added supply can push rents down. The colocation and interconnection side is the defended half: over 232,000 cross connects and the "densely connected data communities" Item 1 says competitors cannot easily replicate, reinforced by contracts the filing describes as generally running 5-10+ years on large deployments and by improvements "installed at our customers' expense." FY2025 leasing supports that read — renewals signed re-priced +27.0% on greater-than-1 MW space and +4.6% on 0-1 MW — while customer concentration is the offsetting exposure, with the largest customer at roughly 11.7% of annualized recurring revenue. | C3.ai's residual moat is intellectual property: a patented model-driven architecture the FY2026 10-K credits with ~26x faster application development, a 33-patent U.S. portfolio including the first foundational agentic-AI orchestration patent, and prebuilt applications encoding 15 years of industry domain knowledge. The same filing concedes its primary competition is do-it-yourself platforms built from hyperscaler and open-source components, and FY2026 results — revenue down ~36% to $250M with GAAP gross margin roughly halved to ~31% — show that IP has not defended pricing or share. |
| Chain position | Landlord to the AI stack — sells the space, power and interconnection that cloud, network and enterprise tenants run compute in (Oracle, IBM, Meta Platforms, AT&T, Comcast and Lumen are among the customers named in Item 1), with roughly 2.9 GW of total in-place IT capacity. | Application-layer pure play: sells prebuilt enterprise-AI applications and an agentic platform to industrial and government end users, downstream of the hyperscaler clouds and LLM providers it deploys on. |
