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.
| Alphabet | KLA Corporation | SK Hynix | |
|---|---|---|---|
| Moat rating | wide Google Search commands ~91% of worldwide search (StatCounter, Jun 2026) and Alphabet sustained a 32% consolidated operating margin on $402.8B of FY2025 revenue (FY2025 10-K), evidence of a durable, dominant advantage. | wide The fiscal 2026 10-K states 'The strength of our competitive positions in many of our existing markets is primarily due to our leading technology', and frames process control as 'an essential enabler' of the yield ramp in fabs the filing says now cost 'well above $10 billion'. | narrow SK hynix held ~62% of the AI-critical HBM market in Q2 2025 (Counterpoint, via TweakTown) and was first to mass-produce HBM4, but memory remains a cyclical three-player business where Samsung and Micron are closing the HBM gap — a real but contestable edge. |
| Moat type | network effects The 10-K states competing in advertising depends on simultaneously attracting and retaining users, advertisers, and content providers — a three-sided marketplace whose value compounds with scale, the classic network-effect flywheel behind ~85% of Alphabet's revenue. | intangibles ip The 10-K reports over 9,100 active patents and over 3,600 pending applications with terms running through 2045, alongside proprietary process-control software (Klarity, I-PAT, aiSIGHT) that turns inspection and metrology data into yield learning. | intangibles ip The advantage is process-and-packaging technology leadership: SK hynix achieved industry-first HBM4 mass production in September 2025 and has positioned itself as NVIDIA's key HBM partner, per its record FY2025 results. |
| Leadership | clear leader Clear leader in its core markets — ~91% of worldwide search and ~69% of mobile OS (StatCounter, Jun 2026) — though only the #3 hyperscaler in cloud infrastructure at ~13%, behind AWS and Azure (Synergy Research, Q2 2025). | clear leader The 10-K opens by describing KLA as a supplier of 'industry-leading equipment and services' and attributes its competitive positions 'in many of our existing markets' primarily to leading technology; named competitors are Applied Materials, ASML, Hitachi High-Tech, Lasertec and Onto Innovation. | clear leader Clear leader in HBM (#1 at ~62% share, Q2 2025) and became the world's top overall memory supplier in Q2 2025; caveat: it sits #2 to Samsung in commodity DRAM by volume and Micron/Samsung are narrowing the HBM gap heading into HBM4. |
| Pricing power | strong A 32% consolidated operating margin held flat 2024→2025 on $402.8B revenue (FY2025 10-K), reflecting strong pricing power in a near-monopoly search-ad auction. | strong Services were approximately 23% of fiscal 2026 total revenues on an installed base that recurs, backlog nearly doubled to $12.57 billion, and SEC-reported net income was 35.6% of revenue in fiscal 2026 with operating income at 41.2% of revenue in fiscal 2025. | strong FY2025 operating margin hit a record 49% (operating profit +101% YoY) as HBM revenue more than doubled — unusually strong pricing power for a memory maker, per SK hynix's FY25 release. |
| Summary | Alphabet's core engine is a three-sided advertising marketplace — the FY2025 10-K says competing depends on simultaneously attracting users, advertisers, and content providers — anchored by Google Search's ~91% worldwide share and Android's ~69% mobile-OS share (StatCounter, Jun 2026), which give it unmatched reach and first-party data. That scale converts to profit: a 32% consolidated operating margin on $402.8B of FY2025 revenue. | KLA sells the inspection, metrology and yield-management layer a fab must run to reach volume production: the 10-K says accelerating the yield ramp ahead of competitors is critical to chipmakers' profitability, and backlog nearly doubled from $7.86 billion to $12.57 billion in the year to June 30, 2026 'due to strong demand driven by the AI infrastructure buildout'. | SK hynix's durable advantage rests on an HBM process-and-packaging lead: it held roughly 62% of the HBM market in Q2 2025 (Counterpoint) as NVIDIA's key HBM partner, and delivered industry-first HBM4 mass production. That lead drove record FY2025 results with a 49% operating margin, though rivals are qualifying competing HBM parts. |
| Chain position | Full-stack AI player: designs its own TPU accelerators, operates Google Cloud (the #3 hyperscaler), and develops the Gemini frontier models — both a supplier of AI compute and a developer of AI products. | Sits beside the process steps rather than in them — it measures and inspects what deposition, etch and lithography produce, and TSMC alone exceeded 10% of revenue in each of the last three fiscal years. | Primary supplier of HBM (high-bandwidth memory) stacked onto NVIDIA's AI accelerators; HBM represented roughly 77% of Q2 2025 revenue. |
