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.
| Space Exploration Technologies Corp. (SpaceX) | Advantest | Broadcom | |
|---|---|---|---|
| Moat rating | narrow The moat is narrow rather than wide. The filing names real entry barriers in launch — capital, technological expertise, licences and established government and commercial relationships — and adds spectrum and orbital resources in connectivity, while warning that the company's "leadership position in various markets, especially in orbital launch services" could attract competition-law scrutiny. The AI segment has barriers too: "Our AI businesses likewise compete in markets characterized by significant barriers to entry." Durability is capped by three-to-five-year satellite lives that force perpetual replacement launches, but the moat is not eroding: subscribers are 12.0M against 6.0M. | wide A disclosed share that rose while margin expanded. The FY2025 Annual Securities Report and Business Report (84th term, filed 2026-06-26) lists as FY2025 progress: 'Further expanded our market share in the semiconductor tester (ATE) market (CY2024: 58%; CY2025: 65%)', earned on net sales of ¥1,128,610 million at an operating income to net sales ratio of 44.2%, 'an increase of 14.9 percentage points from the previous fiscal year'. The share is a company metric and the filing says so — 'the ratio of Advantest's semiconductor tester sales to the overall size of the semiconductor tester market', where 'The semiconductor tester market size is estimated independently by Advantest based on certain assumptions and available information'. The same filing names seven principal tester competitors (Teradyne, Inc., CCTech, Accotest, YC Corp., Cohu, Inc., UniTest Co., Ltd. and EXICON Ltd.), so this is a lead held against a named field rather than an empty one. | wide The FY2025 10-K describes category-leading franchises across a broad semiconductor portfolio plus acquired infrastructure software (VMware, CA, Symantec), with top-five end customers at approximately 40% of net revenue — diversified concentration by AI-supply-chain standards — and the Q3 FY2026 release shows non-GAAP operating margin guided at approximately 66% of revenue while revenue grew 86%. |
| Moat type | cost scale The advantage is cost and scale. The stated model is extreme vertical integration plus reusability driving unit cost down: per NASA, the first Falcon 9 cut launch cost to about $2,700/kg, roughly 85% below the $18,500/kg historical average, and Falcon 9 has "demonstrated the ability to refly a first-stage 34 times" (3/31/26). The filing credits rising cadence, cargo capacity and "declining unit costs—driven by rapid reusability—have generated a compounding competitive advantage". SpaceX also launches its own constellation, and Competition notes "some of these service providers are also launch customers of SpaceX". Spectrum and licence intangibles reinforce the cost advantage. | intangibles ip What management itself names as the source of the position is a proprietary platform. The July 29, 2026 Q1 FY2026 results briefing states: 'Our leading SoC Test platform, V93000, has been widely adopted across a broad range of customers in the increasingly complex AI semiconductor markets, where advanced packaging technologies including GPUs, ASICs, and CPUs are being adopted. It serves as a key foundation that underpins our competitive advantage.' The 84th-term report shows the spend behind it: R&D was approximately ¥71.4 billion in FY2024 and ¥78.1 billion in FY2025, 'The number of employees in its research and development division is approximately 30% of the Advantest workforce', and in the Test System Business Segment 'a large and ongoing investment in research and development is necessary in order to maintain market competitiveness'. Its stated IP mitigation is that 'Advantest strategically and proactively files patent applications during product development and prior to product shipment'. | switching costs The 10-K describes custom accelerators (XPUs) co-designed for hyperscalers and AI frontier-model companies — multi-year, customer-specific silicon programs — alongside enterprise infrastructure software; both are positions a customer leaves only at high cost. |
| Leadership | clear leader SpaceX leads clearly in its two established segments but not in its newest. The prospectus calls it "the primary launch provider for the U.S. government" — 11 of 12 NSSL medium and heavy lift missions and all five U.S. crew and cargo ISS missions for NASA in 2025 — and says Starlink is "the sole low-latency network available globally", low-latency self-defined as under 70ms; it flags competition-law scrutiny risk from that leadership. AI is the exception, with OpenAI, Anthropic, Google, Meta and Microsoft named as competitors, some with greater resources, in a segment the filing calls early stage. Cadence slipped: H1 2026 Falcon launches 77 versus 81, mass to orbit 1,041t versus 1,102t. | clear leader The 84th-term report discloses Advantest's tester-market share at 65% in CY2025, up from 58% in CY2024, and carries the same 65% among its disclosed management metrics against a target of '58% or more'; the filing defines it as Advantest's semiconductor tester sales over a market size 'estimated independently by Advantest based on certain assumptions and available information'. The July 29, 2026 briefing names the platform behind that share — V93000, 'widely adopted across a broad range of customers in the increasingly complex AI semiconductor markets'. Teradyne, Inc. heads the filing's list of principal tester competitors. | clear leader The 10-K claims 'category-leading semiconductor and infrastructure software solutions' — the company's own attribution — and the Q3 FY2026 release reports AI semiconductor revenue of $16.7 billion in one quarter, up 221% year over year, a scale no other custom-accelerator design house reports. |
| Pricing power | moderate Pricing power is moderate — a deliberate give-back from a cost position rather than weakness. Management states its strategy is "rather than prioritizing increases in ARPU" and expects Starlink ARPU to keep declining as it adds lower-priced plans and adjusts monthly service fees; the Q2 10-Q shows ARPU of $66 versus $85 while Connectivity operating income rose 79.4%. Launch sells on fixed-price contracts, one to five years for Launch Services and up to fourteen for Launch and Development. Concentration is material: about one-fifth of 2025 revenue came from U.S. federal agencies, with all launch contracts firm fixed-price and terminable at the government's convenience without advance notice. | strong Q1 FY2026 gross profit was ¥255,553 million on net sales of ¥367,473 million, and the July 29, 2026 briefing states the resulting figure itself: 'Gross margin reached 69.5%', with 'an operating margin of 51.7%'. Management attributes that level to 'a favorable sales mix and limited inventory valuation losses amid the robust demand environment', not to price, and guides FY2026 full-year gross margin to 66–67% and operating margin to 49.4% after incorporating 'the impact of higher component costs, particularly for memory-related components'. FY2025 closed at a 44.2% operating margin, up 14.9 points year on year, on sales up 44.7%. | strong Q4 FY2026 non-GAAP operating income is guided at approximately 66% of revenue, flat from a year ago, while consolidated revenue is guided up 93% — margin held through a near-doubling of revenue. |
| Summary | Two real moats and one expensive bet. Launch and Starlink rest on facts the filing states outright: barriers of capital, technology, licences, spectrum and orbital resources; about 9,600 satellites, roughly 75% of all active maneuverable satellites in orbit; the only globally available low-latency network; a NASA-cited cost per kilogram about 85% below the historical average; a first stage reflown 34 times. Connectivity rivals buy launches from it. What caps it: satellites live three to five years and must be perpetually replaced; H1 2026 Falcon launches and mass to orbit both fell and Falcon 9 flights are expected to decline; about 20% of 2025 revenue is U.S. federal, competitively bid and terminable at will; 86% of Q2 capex ($15.8bn of $18.4bn) went to an AI segment whose cloud revenue sits with few customers on 90-day-terminable contracts. Q2 operating loss $143M; H1 loss $2,086M. | Advantest sells the test step that certifies silicon before it ships, and its position there is disclosed rather than inferred: its own tester-market-share metric moved from 58% in CY2024 to 65% in CY2025 (84th-term Annual Securities Report), against a market size the filing says Advantest estimates itself. The lead is concentrated in SoC test — the July 29, 2026 briefing calls V93000 'our leading SoC Test platform' and 'a key foundation that underpins our competitive advantage' — and the customer base runs straight into the AI chain: NVIDIA International, Inc. was ¥228,273 million, or 20.2%, of FY2025 consolidated net sales, having been below the filing's 10% disclosure threshold the prior year, with Taiwan Semiconductor Manufacturing Co., Ltd. at ¥124,922 million, or 11.1%. Economics moved with it: FY2025 operating margin was 44.2%, up 14.9 points, and Q1 FY2026 gross margin reached 69.5%, which management attributes to 'a favorable sales mix and limited inventory valuation losses amid the robust demand environment' rather than to price. The counterweights sit in the same documents. The 84th-term report's customer-trust risk factor warns that if Advantest fails to meet expectations on ramp-up and post-sales service, 'the maintenance or expansion of Advantest's market share may be constrained'; it names separate competitor sets in test handlers (Hon. Precision, CCTech, Cohu, TechWing) and device interfaces (TSE, ISC, BeLINK) where no share is disclosed at all; and the July 29, 2026 briefing guides FY2026 full-year gross margin down to 66–67% having 'incorporated the impact of higher component costs, particularly for memory-related components, mainly in the second half of the fiscal year'. | Broadcom holds two moats under one roof. In AI silicon it is the design partner for custom accelerators and the merchant supplier of the Ethernet switching, NIC, PHY and optical parts that connect them — 'connectivity at scale, within and across AI server racks and across AI data center sites' in the filing's words. In software it owns acquired enterprise franchises. The 10-K's own competition section flags the counterweight: competition is increasing 'as new companies, including some of our customers, enter the markets.' |
| Chain position | — | Back-end capital equipment: Advantest's testers certify devices after fabrication, and the 84th-term report's FY2025 major-customer table puts NVIDIA International, Inc. at 20.2% and Taiwan Semiconductor Manufacturing Co., Ltd. at 11.1% of consolidated net sales, with overseas sales 97.8% of the total. | Layer-4 chip supplier twice over: custom accelerators for hyperscalers and the Ethernet switching/optical silicon between every AI rack. |
