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.
| Cerebras Systems | SanDisk | GE Vernova | |
|---|---|---|---|
| Moat rating | narrow One-of-a-kind silicon sold to very few buyers: the IPO prospectus discloses G42 at 24.0% of 2025 revenue (85.0% in 2024), MBZUAI at 62.0% of 2025 revenue, and a December 2025 MRA with OpenAI representing 'a substantial portion of our projected revenues over the next several years' — against a competitive field the same document names as NVIDIA, AMD, Intel, hyperscaler accelerators and the major clouds. | narrow Narrow rather than wide: the FY2025 10-K Competition section opens 'Our industry is highly competitive' and names five vertically integrated flash rivals (Kioxia, Micron, Samsung, SK Hynix, Yangtze Memory), while Item 1A concedes SanDisk's products 'are designed to be largely interchangeable with competitors' products' in a market 'often subject to declining average selling prices'. It is not 'none', because the same filing discloses a genuinely durable consumer franchise and roughly 7,900 granted patents. | 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 | intangibles ip Wafer-scale integration is the moat's substance: the prospectus contrasts the WSE-3's 4 trillion transistors on 46,225 mm² of silicon with NVIDIA's B200 at 208 billion on roughly 1,600 mm² — a commercial chip category with one occupant. | intangibles ip The only hard-to-replicate assets the filing actually claims are intangible: it reports 'a strong position in the Consumer end market' with 'significant consumer brands and franchises globally, with valuable patent portfolios containing approximately 7,900 granted patents and approximately 3,200 pending patent applications worldwide', and adds that non-patented IP, 'particularly some of our process technology, is an important factor in our success'. Cost-scale is the wrong label because the manufacturing scale sits in Flash Ventures, a 49.9%-owned JV co-owned with Kioxia, not in a proprietary fab base. | 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 | clear leader Scoped to the category the record supports: wafer-scale integration has no other commercial occupant per the prospectus's own comparison, and the Q2 release claims — attributed, via AMD and AWS partnerships — leadership in disaggregated inference, a technique the prospectus defines. | at parity At parity, not ahead: the 10-K Competition section positions SanDisk against vertically integrated suppliers Kioxia, Micron, Samsung, SK Hynix and Yangtze Memory, and Item 1A concedes its products are 'designed to be largely interchangeable with competitors' products'. Its explicit leadership claims are brand- and consumer-scoped ('industry leading consumer brand awareness and global retail distribution presence'), not technology- or share-scoped. | 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 | moderate The CFO states Q2 'significantly improved core gross and operating margins compared to a year ago' — improving, from a base where three named customers hold most of the revenue and the leverage that comes with it. | weak A price taker. The 10-K describes an industry 'often subject to declining average selling prices' and warns that competitors 'may utilize pricing strategies, including offering products at prices at or below cost, that we may be unable to competitively match'. Gross margin swung from 7.1% (FY2023) to 16.1% (FY2024) to 30.1% (FY2025) on the cycle rather than on sustained pricing, and FY2025 Consumer ASP per gigabyte still fell 7% 'due to pricing pressure'. | 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 | Cerebras bet that AI compute should be one enormous chip rather than many small ones — 'quantities of compute and memory never before assembled on a single commercial chip,' avoiding 'the latency and the power-draw induced by the traditional approach,' in the prospectus's words — and is converting that bet into an inference cloud: Q2 2026 cloud revenue grew 281% with 600 MW of data center capacity under contract and $25.4 billion of remaining performance obligations. The concentration that funded the bet is the risk that remains: two related-party Gulf customers were 86% of 2025 revenue between them, with the OpenAI MRA now layered on top. | SanDisk sells largely interchangeable NAND product into a five-rival commodity market, so its defensible edge is narrow and concentrated in intangibles: the SanDisk consumer brand and retail distribution (Consumer was $2,268M of $7,355M FY2025 revenue) plus roughly 7,900 granted patents. It owns no flash fab of its own; the 10-K says substantially all of its flash memory wafers come from Flash Ventures, its 49.9% JV with Kioxia, whose fixed costs it must fund at about half regardless of the output it takes. That structure caps both the moat and the downside cushion: gross margin ran 7.1% in FY2023, 16.1% in FY2024 and 30.1% in FY2025 as the flash cycle turned. | 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-4 wafer-scale accelerators plus an inference cloud — hardware vendor and specialized cloud in one node. | Merchant NAND/SSD supplier with no wholly owned fab: substantially all flash wafers come from Flash Ventures, its 49.9% JV with Kioxia across seven Japanese fabs, with an eighth due to start in calendar 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. |
