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 | Qualcomm | |
|---|---|---|---|
| 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 Qualcomm's advantage is real but concentrated in one segment. The FY2025 10-K (filed 2025-11-05) describes its portfolio as "the most widely and extensively licensed in the industry" and says the industry "generally recognizes that any company seeking to develop, manufacture and/or sell certain cellular products requires a license or other rights to use our patents". That licensing leg produced $5,582M of FY2025 revenue against $38,367M at QCT, where Apple, Samsung and Xiaomi are all named in the vertical-integration risk factor and Apple already "utilizes its own modem... in certain of its smartphones". The filing frames the QCT loss as expected rather than realised. |
| 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 durable asset is intellectual property accumulated since Qualcomm's founding "in 1985". The patents have "broad coverage in many countries, including Brazil, China, India, Japan, South Korea, Taiwan, the United States and countries in Europe" and are licensed "to hundreds of companies on industry-accepted terms", with royalties set as "a percentage of the wholesale (i.e., licensee's) selling price... subject to per unit minimums and/or per unit caps". R&D of $9,042M equalled 20% of revenues. Manufacturing is fabless "other than for certain of our RFFE modules and RF filter products", for which Qualcomm owns fabs in Germany and Singapore. |
| 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 Leadership is clear in licensing and contested in silicon. The 10-K names no rival licensing programme and asserts the portfolio is "the most widely and extensively licensed in the industry", while calling QCT's industries "intensely competitive" and naming eleven competitors (Broadcom, HiSilicon, MediaTek, Mobileye, Nvidia, NXP, Qorvo, Samsung, Skyworks, TI, UNISOC); "continue to be a leader in mobile" appears in a list of things future success depends on, so it reads as aspiration, not share. The band therefore rests on the licensing leg, roughly 13% of revenue. FY2025 10%-plus customers were 21%, 20% and 13%; in 9M FY2026 only two cleared 10%. |
| 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 QTL margins held at 72% in FY2025 and 73% in 9M FY2026, though Q3 FY2026 alone slipped to 69% from 71%, and the $111M revenue gain there is attributed to revenues per unit "primarily driven by favorable mix" rather than to price. At QCT, the fall to 26% from 30% is explained by "lower gross margin, primarily driven by higher product cost, partially offset by higher average selling prices" plus lower revenues, so the pressure is cost rather than price; FY2025 handsets rose $2,930M, of which $2.5B came from higher revenue per chipset. Against that, "declining average selling prices" is a standing risk-factor title, "particularly pronounced in emerging regions and China". |
| 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. | Qualcomm has two legs pointing in opposite directions. QTL (FY2025 revenue $5,582M, EBT margin 72%) rests on a portfolio the 10-K calls "the most widely and extensively licensed in the industry", with royalties struck on the licensee's wholesale device price under per-unit minimums and caps; its durability is dated in the filing, since "our patent license agreements with key OEMs are generally long-term, with terms expiring at varying dates between fiscal 2027 and 2031", some with binding-arbitration renewal clauses, and Huawei's licence has already expired, removing its royalties from QTL revenue from Q2 FY2025. QCT ($38,367M, 87% of segment revenue) is the leg under pressure: its three 10%-plus customers all build their own silicon, Apple already ships its own modem, and QCT EBT margin fell to 26% in Q3 FY2026 from 30%. |
| 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. | Every figure and quotation is drawn from the FY2025 10-K and the Q3 FY2026 10-Q. Where the filings state no market share, the share band is left unknown rather than inferred, and barrier bands follow the filings' own language, which states a barrier to entry only for automotive. |
