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 | Tokyo Electron | |
|---|---|---|---|
| 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. | narrow Integrated Report 2026 (issued 2026-09-15) documents strong positions across the line: by Tokyo Electron's own estimate it ranks No. 1 in diffusion furnaces, batch deposition, metal deposition, coater/developers, gas chemical etch and wafer probers, No. 2 in plasma etch and bonders and No. 3 in cleaning, and holds a "100% share" of coater/developers for EUV lithography; its installed base, industry-leading by its own estimate, is approximately 100,000 units, growing by approximately 4,000-6,000 units a year; and its 26,592 patents rank No. 1 in the semiconductor production equipment industry on the LexisNexis PatentSight+ database. Reported returns stayed high through a sales decline: gross profit margin stayed between 44.6% and 47.1% and ROE between 21.8% and 37.2% across fiscal 2022-2026, including fiscal 2024 when net sales fell to ¥1,830.5 billion. The share ranks, the EUV share and the installed-base lead are company estimates, not third-party data. |
| 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. | intangibles ip The report calls its patent portfolio its "fifth strength" and says that "by supporting our other four strengths, it serves a vital role as the foundation" for medium- to long-term corporate value: 26,592 patents as of March 31, 2026, 1,415 inventions created in Japan and 345 overseas in 2025, and Clarivate Top 100 Global Innovators recognition for the fifth consecutive year. The other strengths rest on the same proprietary process know-how — co-created technology roadmaps that evaluate technologies "for the next four generations and beyond" with customers, "numerous development PORs" (process of record) in the frontend business, and the EUV coater/developer position — so proprietary process technology, reinforced by qualification in customers' process flows, is the moat source. |
| 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 The CEO's message describes Tokyo Electron as "one of the world's leading suppliers of semiconductor production equipment" and states a "goal of becoming number one globally" — it does not claim to be the largest supplier overall — while by its own estimate it ranks No. 1 in six charted segments (diffusion furnace, batch deposition, metal deposition, coater/developer, gas chemical etch, wafer prober), No. 2 in plasma etch and bonders, and No. 3 in cleaning. |
| 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'. | moderate Gross profit margin held in a 44.6%-47.1% range over fiscal 2022-2026, including fiscal 2024's sales decline, but in fiscal 2026 it fell 1.8 points to 45.3% "due to factors such as higher raw material prices and increased labor costs" even as net sales reached a record, and the CEO lists "revising prices appropriately with respect to cost increases caused by inflation" among five initiatives needed to improve the operating margin. |
| 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. | Tokyo Electron makes wafer fab equipment for what its Integrated Report 2026 calls the "four key processes necessary for semiconductor scaling: deposition, coater/developer, etch, and cleaning", plus wafer probers and bonders for test and advanced packaging. The report grounds its edge in breadth and incumbency: leading share estimates in most of its segments, an estimated 100% share of EUV coater/developers, an installed base of approximately 100,000 units, industry-leading by its own estimate, feeding a Field Solutions business that sold ¥626.0 billion of parts, services, used equipment and modifications in fiscal 2026, and the industry's largest patent portfolio. Fiscal 2026 net sales were a record ¥2,443,533 million, but gross profit margin fell 1.8 points to 45.3% on higher raw material prices and labor costs, and operating margin fell 3.1 points to 25.6% as R&D expenses rose 11.1% to ¥277,866 million. China accounted for 34.1% of fiscal 2026 net sales, down from 41.7% the year before. |
| 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. | Upstream equipment supplier to chipmakers: fiscal 2026 new-equipment sales of ¥1,775.4 billion went 59% to non-memory (logic, foundry, others), 31% to DRAM and 10% to NAND; by region, China took 34.1%, South Korea 22.3% and Taiwan 20.4% of net sales. |
