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.
| Nebius Group | Amazon | GE Vernova | |
|---|---|---|---|
| Moat rating | narrow The FY2025 20-F positions Nebius as 'one of the few global, at scale, multi-tenant clouds purpose built for AI,' but the same filing names its central dependency plainly: 'We currently rely on Nvidia for the GPU chips we use' — a purpose-built neocloud renting a supply the hyperscalers it competes with also control, which is a real but narrow position. | wide Amazon's FY2025 10-K describes leading positions across e-commerce, AWS cloud computing, advertising, and devices; paired with AWS's #1 ~29% cloud-infrastructure share (Synergy, Q3 2025) and ~40% US e-commerce share (eMarketer), its fulfillment and data-center scale advantages are durable and hard for any single-segment rival to replicate. | wide FY2025 10-K (filed 2026-01-29): the installed base generates approximately 25% of the world's electricity; the Power segment carries ~$94.4B of remaining performance obligations with ~1,800 of ~7,000 installed gas turbines under long-term service agreements averaging ~10 years of remaining contract life; and the filing states demand is 'exceeding available capacity' for its products — a contracted, decade-scale service annuity on proprietary installed equipment. |
| Moat type | cost scale The moat the filing describes is engineering: designs that 'optimize power and cooling efficiency, lower latency' plus 'a consistent track record of being one of the first-to-deploy the latest generation of NVIDIA GPU chips' — density and time-to-deploy at scale, not a switching lock. | cost scale Amazon's through-line advantage is scale economics — a fulfillment/logistics network and AWS data-center infrastructure whose fixed costs are spread over volumes competitors cannot match; the FY2025 10-K lists "fast and reliable fulfillment" and scale among principal competitive factors, and AWS's ~35% operating margin ($45.6B operating income on $128.7B revenue, FY2025) reflects that scale edge (marketplace network effects and AWS/Prime switching costs reinforce it). | switching costs 10-K: ~1,800 gas turbines under long-term service agreements with ~10-year average remaining life, plus services agreements on ~24,000 of ~59,000 installed onshore wind turbines — service revenue is contractually tied to GE Vernova's own installed fleet; the filing adds it derives 'a sustained competitive advantage both from our IP portfolio as well as technical know-how embedded in our products and manufacturing techniques developed over decades'. |
| Leadership | fast follower The 20-F's own claim is 'one of the FEW global, at scale' AI clouds — a differentiated challenger to the hyperscalers it names as the competitive field, not a claimed leader of it; the first-to-deploy record is a follower's speed advantage, not category leadership. | clear leader Leader in cloud infrastructure (AWS #1 at ~29% in Q3 2025 vs Microsoft 20% and Google 13%, per Synergy Research) and in US e-commerce (~40% share, far ahead of #2 Walmart, per eMarketer); #3 in global digital advertising. | co leader 10-K opens with 'GE Vernova is a global leader in the electric power industry' and its installed base generates ~25% of world electricity, but the filing names peer-scale competitors in every segment — Siemens Energy in both Power and Electrification, Mitsubishi Power, Vestas, Hitachi Energy, Schneider Electric, ABB — so co-leader across the portfolio rather than clear leader. |
| Pricing power | weak The filing frames a 'highly competitive' market with 'frequent introduction of new or improved solutions' and a GPU cost base set by a single supplier (NVIDIA) — a renter of compute competing on efficiency has little list-price control. | moderate Mixed by segment: retail is explicitly price-competitive — the FY2025 10-K lists "price" among principal competitive factors and notes AWS pricing is shaped by long-term customer contracts — but AWS's ~35% operating margin and recurring Prime price increases evidence real pricing power in cloud and membership. | strong 10-K: 'increasing demand exceeding available capacity', Electrification customer lead-times 'increased as a result of demand outstripping supply', and both Power and Electrification state they adjust pricing 'in line with market demand, inflation, and industry dynamics'; trade press (Power Engineering, 2026-04-23) reported new gas-turbine order pricing in H1 2026 tracking 10-20 points higher on a dollar-per-kilowatt basis than Q4 2025 orders. |
| Summary | Nebius sells a 'unified full-stack AI cloud that spans the complete AI journey – from compute capacity to software and services,' with hardware and software built in-house — the neocloud pitch of hyperscaler reliability at purpose-built efficiency, and a first-to-deploy record on new NVIDIA silicon. Two things bound the moat, both from the filing: it 'currently rel[ies] on Nvidia for the GPU chips,' the same constraint every neocloud shares, and it is a Nasdaq 'Controlled Company' whose founding shareholder holds concentrated voting power. The three non-core segments (Toloka, Avride, TripleTen) are separate businesses, not the cloud moat. | Amazon compounds a two-sided marketplace, a Prime membership flywheel, and the world's #1 cloud platform (AWS) into mutually reinforcing scale: per its FY2025 10-K, AWS generated $45.6B of operating income on $128.7B of revenue (~35% margin) and funds retail's low-price strategy, while an unmatched fulfillment network and ~40% US e-commerce share (eMarketer) raise the barrier for any single-segment challenger. | GE Vernova's moat rests on its installed base: the FY2025 10-K states its equipment generates approximately 25% of the world's electricity, with ~7,000 installed gas turbines (~1,800 under long-term service agreements averaging ~10 years of remaining life) and ~$94.4B of Power-segment remaining performance obligations. The filing reports demand 'exceeding available capacity', lengthening Electrification lead-times 'as a result of demand outstripping supply', and pricing adjusted with demand — scarcity trade press later quantified as new gas-turbine order pricing tracking 10-20 points higher per kW in H1 2026 than Q4 2025, with only ~10 GW of production slots left across 2029-2030 (Power Engineering, 2026-04-23). The moat is not uniform: the 10-K risk section flags intensifying competition as manufacturers from China 'improve quality and reliability and pursue markets outside their home countries', and Offshore Wind is delivering its backlog under project-cost and execution pressure, compounded by the U.S. Interior Department's December 22, 2025 pause of leases for all large-scale U.S. offshore projects under construction, which directly impacted the Vineyard Wind timeline. Nuclear adds optionality: the 10-K cites an SMR deployment agreement it calls 'the first commercial contract of its kind in North America' via its joint ventures with Hitachi. |
| Chain position | Layer-8 neocloud — a purpose-built AI compute provider reselling NVIDIA silicon at scale. | Via AWS — the #1 cloud infrastructure platform — Amazon is a core supplier of compute, storage, and AI/ML services to the broader AI industry (FY2025 10-K; Synergy Q3 2025). | Power supplier to the AI buildout: the 10-K states gas power serves 'rising electricity demand from hyperscalers and data centers' and Electrification benefits from orders to electrify data centers 'playing a key role in the development of artificial intelligence (AI)'; trade press (Power Engineering, 2026-04-23) put roughly 20% of the ~100 GW of gas capacity under contract as explicitly tied to data-center load. |
