| 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. | none The FY2026 10-K (filed 2026-08-27) shows IREN holds an input the industry competes on: it names 'access to secured and energized power' first among what it believes are the principal competitive factors in its industry, and reports 'executed grid connection agreements, letters of agreement or equivalents representing approximately 5GW of total power capacity' in the United States, Canada, Spain and Australia as of June 30, 2026. It does not claim an advantage over rivals in that input. It says 'Certain competitors may have access to more competitively priced power, a greater access to power and a better capacity to timely secure grid connections,' and 'Many of our competitors have greater financial, technical or commercial resources, longer cloud operating histories or larger customer bases, compared to us.' Operating AI Cloud Services capacity was approximately 40MW at June 30, 2026, and the stored XBRL fundamentals from this 10-K show an FY2026 operating loss of about $1,046.7M on revenue of about $707.0M, so no durable advantage is yet demonstrated. | narrow The 2025 annual report (published 2026-04-30) shows a real but shallow position: products deployed in "more than 750 hyperscale data centers" and, on the Company's own internally assessed shipment volume, "more than 10% of global server shipments and nearly 30% of global ODM-Direct server shipments" in 2025 — while the same report's own list of negative factors names "Excessive concentration of customers" and a market "getting more and more competitive", discloses three customers at 41.48%, 26.03% and 10.43% of 2025 net sales, and reports 2025 gross profit up 109.77% against revenue up 163.68% for an 8.3% gross margin. Defensible incumbency, not a durable one. |
| 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. | none The FY2026 10-K's asserted advantage is control from owning its data centers, 'including the associated land, grid connections and substations', which it believes allows it 'to benefit from more sustainable cash flows and operational flexibility relative to operators that rely upon third-party colocation services or short-term land leases'. Its only scale language is a belief that its 'procurement scale, deployment experience and direct control over the data center layer' lets it bring new compute into service 'rapidly and at scale', a deployment-speed claim, and it 'generally target[s]' regions with 'low-cost and attractive renewable energy sources', a siting target rather than a demonstrated cost position. It does not claim a cost or scale lead: it says 'Many of our competitors are larger, have longer operating histories and significantly greater resources than we do' and that certain competitors 'may have access to more competitively priced power, a greater access to power and a better capacity to timely secure grid connections.' There is no network effect or lock-in either, since existing contracts have 'terms ranging from month to month up to five years'. No enumerated moat source is grounded. | switching costs The report's "Competitive niche" section locates the advantage in the customer program rather than in IP or unit cost: "highly customized solutions for hyperscale data centers", "end-to-end technical integration capabilities ranging from server design and system integration to large-scale L10/L11 rack-level delivery", and a one-stop service "covering product design, integration, optimization, deployment, and after-sales services" across a base of more than 750 hyperscale data centers. Every advantage the section claims is about integration work and customer proximity, none about patents or proprietary silicon, and an 8.3% gross margin is not the profile of a cost advantage; what is left is the friction in an installed, co-designed rack program. |
| 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. | behind The 10-K lists IREN's competitors as hyperscalers (Amazon Web Services, Google Cloud, Microsoft Azure, Oracle Cloud) and specialized AI Cloud Services providers (CoreWeave, Nebius, Crusoe, Lambda, Nscale, SpaceX and others). It says IREN began providing AI Cloud Services in 2024 and cites its 'shorter operating history in AI Cloud Services relative to some competitors', and states 'Some of our competitors have longer operating histories, larger customer bases, more comprehensive IP portfolios and patent protections, more design wins, and greater financial, sales, marketing and distribution resources than we do.' Operating AI Cloud Services capacity was approximately 40MW at June 30, 2026. The filing describes a smaller, later entrant that trails some competitors on operating history, customer base and resources, with its progress so far resting on two anchor contracts (a ~$9.7B five-year Microsoft agreement and a ~$3.4B five-year NVIDIA contract) rather than any claimed category position. | co leader The report claims "nearly 30% of global ODM-Direct server shipments" for 2025 on internally assessed volume, against an IDC Worldwide Quarterly Server Tracker base of approximately 7.7 million ODM-Direct units within roughly 16.78 million total 2025 server shipments — yet describes the Company only as "one of the major suppliers to international hyperscale data centers". Among the largest in its segment; the report makes no claim to be first. |
| 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 The 10-K's risk factors state 'Our competitors' products, services and technologies may be cheaper or provide better functionality or features than ours, which has resulted and may in the future result in lower-than-expected selling prices or demand for our products.' They also say long-term contract pricing 'is generally fixed or agreed at the time of contracting', so if market pricing for comparable capacity rises during a contract's term 'we will not benefit from those increases with respect to capacity already committed under our existing long-term contracts', and that if customers suffer a downturn or discontinue its services it 'may be compelled to offer more flexible terms, lower our prices or risk losing a significant customer.' The stored XBRL fundamentals from this 10-K show FY2026 revenue of about $707.0M against an operating loss of about $1,046.7M, so there is no margin record yet that evidences pricing power. | weak 2025 gross margin was 8.3% and operating margin 6.7%; gross profit rose 109.77% while revenue rose 163.68%, so the margin narrowed as volume grew. The report discloses three customers at 41.48%, 26.03% and 10.43% of 2025 net sales, lists "Excessive concentration of customers" among its negative factors, and explains its main-supplier table with "The suppliers are designated by customers." |
| 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. | Per its FY2026 10-K, IREN is a vertically integrated AI Cloud Services platform that owns the data center, compute and software layers, underpinned by executed grid connection agreements, letters of agreement or equivalents representing ~5GW and a further multi-GW development pipeline. Its commercial record is concentrated: a five-year Microsoft agreement (~$9.7B total contract value, Horizon 1 delivered and accepted in August 2026, Horizons 2-4 targeted for delivery in phases in calendar Q4 2026) and a five-year ~$3.4B NVIDIA cloud contract together make up a substantial majority of contracted revenue. It holds NVIDIA Preferred Partner and Exemplar Cloud status (HGX B300 and GB300 NVL72) and a strategic partnership intended to support the deployment over time of up to 5GW of NVIDIA DSX-aligned infrastructure, which the filing cites among arrangements that are non-binding or subject to conditions, with no assurance as to the extent of deployments. Against that, the filing names hyperscaler and specialized competitors (AWS, Google Cloud, Azure, Oracle, CoreWeave, Nebius, Crusoe, Lambda, Nscale, SpaceX), many of which it says have greater resources, customers that can use or develop their own solutions, and possible delays to Texas energization from changes to ERCOT's Batch Zero procedures, so the power position is not a demonstrated advantage over rivals and its value depends on execution. | Wiwynn sells ODM-Direct — it designs and builds cloud and AI server systems to hyperscale operators' specifications rather than shipping a branded product — and the 2025 annual report grounds its edge in that relationship: "highly customized solutions", integration "from server design and system integration to large-scale L10/L11 rack-level delivery", Open Compute Project participation described as "a core competitive advantage in marketing to global hyperscale data centers", and products deployed in more than 750 hyperscale data centers as of the end of 2025. The report also says that high integration and testing abilities "increases the threshold of vendors in the assembly industry and creates entry barriers". Against that, the same report lists excessive customer concentration and an increasingly competitive market as its negative factors, discloses customers at 41.48%, 26.03% and 10.43% of 2025 net sales, explains its main-supplier table with "The suppliers are designated by customers", and reports an 8.3% gross margin on 2025 revenue of NT$950.66bn. |
| Chain position | Layer-4 wafer-scale accelerators plus an inference cloud — hardware vendor and specialized cloud in one node. | Downstream AI-cloud operator: owns grid-connected data centers and deploys NVIDIA/AMD GPU systems it rents to hyperscalers, frontier labs, AI developers and enterprises (anchor customers Microsoft and NVIDIA). | The report's cloud/AI-server value-chain diagram places system assembling in the midstream and "Direct sales from original manufacturers" downstream selling to cloud service providers; Wiwynn describes itself as providing "IT equipment and rack system integration service to hyperscale data centers". 82.12% of 2025 revenue came from America. |
