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.
| Tencent Holdings | Amkor Technology | TSMC | |
|---|---|---|---|
| Moat rating | wide The 2025 Annual Report reports combined MAU of Weixin and WeChat of 1,418 million at 31 December 2025, still growing 2% year-on-year and 0.3% quarter-on-quarter off a 1.4-billion-account base, while group gross margin rose to 56% from 53% and Marketing Services revenue grew 19% to RMB145.0 billion 'primarily driven by growth in pricing and ad impressions'. Rising price on a still-growing user base of that size is the signature of a wide moat, not a contested one. | narrow The FY2025 10-K describes a real but bounded edge. On the plus side, Amkor says "Our scale and geographic diversity allow us to qualify production at multiple sites, optimize asset utilization and absorb large orders that require quick turnaround." It also says "Amkor has built long-standing relationships with most of the world's leading semiconductor companies over the last five decades." And it says that "in line with industry practice, customers usually require us to pass a lengthy and rigorous qualification process that may take several months". It falls short of wide because the same filing calls the market "highly competitive", names ASE Technology, JCET Group and Powertech Technology as rivals, and says Amkor faces Asian providers "including companies with significantly greater processing capacity, financial resources". It also says foundries "substantially larger than us" have expanded into packaging and test, and that IDMs and foundries "may decide to shift some or all of their outsourced packaging and test services to internally sourced capacity". Returns are thin: MD&A gross margin was 14.0% in 2025, 14.8% in 2024 and 14.5% in 2023, with a 7.0% operating margin in 2025. | wide TSMC's 2025 Form 20-F reports a 59.9% gross margin (up from 56.1% in 2024) and describes the company as "the technology leader among the dedicated foundries" in advanced (7-nanometer-and-below) node revenue — a durable, hard-to-replicate process-and-scale advantage that rivals with "greater financial and other resources" have not matched. |
| Moat type | network effects The report attributes Marketing Services pricing growth to 'an increasing proportion of closed-loop ads (where the user clicks through to native transactional experiences, such as Mini Programs, Mini Shops, or Mini Games)' and describes growing engagement with Mini Shops, Mini Games and content Mini Programs 'by strengthening Weixin's commerce experience and content ecosystem' - merchants and developers building inside the user graph rather than beside it, which is a network effect rather than a switching cost or a scale cost advantage. | cost scale Part of the 10-K's cost/scale case applies to the whole industry, not to Amkor alone. It says packaging and test service providers "can typically use their assets to support a broad range of customers and multiple end markets, potentially generating more efficient use of their production assets and a more cost-effective solution", in contrast to IDMs running their own lines. The Amkor-specific support is its footprint, which it calls "a key differentiator", and its purchasing scale: "By leveraging our purchasing power and operational expertise, we look to secure favorable pricing and supply agreements for materials and equipment, further enhancing our competitive position." It adds: "We also negotiate worldwide pricing agreements with our major suppliers to take advantage of the scale of our operations." Against other OSATs the scale edge is limited, because Item 1A concedes Asian rivals "including companies with significantly greater processing capacity, financial resources". Multi-month customer qualification and long customer relationships add a secondary switching-cost element. IP is not the source: "Although our patents are an important element of our intellectual property strategy, we are not materially dependent on any one patent or any one technology." | intangibles ip Per its 2025 Form 20-F, TSMC "compete[s] primarily on process technologies, manufacturing excellence, customer trust and service quality" and has "been issued a substantial number of patents," with 2-nanometer in volume production in 2025 and 16-angstrom risk production targeted for 2026 — proprietary process-technology know-how and IP, not merely capital (the filing explicitly notes some competitors may have greater financial resources yet still trail), are the core barrier. |
| Leadership | clear leader The only explicit leadership claims in the report are the Company's own: Tencent Video 'maintained its leading position in China's long-form video market' and Tencent Music 'extended its leading position in China's music streaming market'. Against a 1,418 million combined Weixin/WeChat MAU base, the report asserts leadership in the adjacent content markets and no competitor is named anywhere in it. | co leader The FY2025 10-K opens: "Amkor is the world's largest U.S. headquartered outsourced semiconductor assembly and test service provider (“OSAT”) and is a global leader in outsourced semiconductor packaging and test services." It claims to be a global leader, not the leader, and its one superlative is limited to U.S.-headquartered providers. It names ASE Technology, JCET Group and Powertech Technology as rivals. It concedes Asian competitors "including companies with significantly greater processing capacity, financial resources". About the key competitive factors it lists, it says only "We believe we are competitive in these areas." | clear leader Self-described in its 2025 20-F as "the technology leader among the dedicated foundries" in net revenue of advanced semiconductors at 7-nanometer and below; reached 2nm volume production in 2025, and Epoch AI estimates ~90% share of global advanced-node fabrication. |
| Pricing power | strong Group gross margin was 56% for 2025, up from 53%, with segment gross margins of 60% for VAS (from 57%), 58% for Marketing Services (from 55%) and 51% for FinTech and Business Services (from 47%); Marketing Services revenue growth is attributed 'primarily' to pricing, and the Chairman's Statement notes ad load 'remained at a much lower level than peers'' - price is rising with monetisation headroom still unused. | weak Item 1A of the FY2025 10-K says "Prices for packaging and test services have generally declined over time, and sometimes prices can change significantly in relatively short periods of time." It also says "We expect downward pressure on average selling prices for our packaging and test services to continue in the future, and this pressure may intensify during downturns in business." MD&A gross margin was 14.0% in 2025 against 14.8% in 2024 and 14.5% in 2023. The notes say the longer test-equipment depreciation life "reduced depreciation expense by approximately $59 million in 2024". Materials alone were 55.2% of 2025 net sales. The customer base is concentrated: the ten largest customers were 72% of 2025 net sales, with Apple at 29.8% and Qualcomm at 11.1%, and the filing flags "a reduction in orders or decrease in price from a significant customer" as a risk. | strong 2025 gross margin of 59.9% (up from 56.1% in 2024), attributed in the 20-F to higher capacity utilization and cost improvement, reflects strong pricing power at the leading edge despite the heavy capital intensity of new-node ramps. |
| Summary | The textbook answer holds, but not for the textbook reason. Weixin's value is that third parties transact inside it: the report ties Marketing Services growth to closed-loop ads landing in Mini Programs, Mini Shops and Mini Games, ties Business Services growth to 'higher eCommerce technology service fees, underpinned by growth in Mini Shops GMV', and reports that ad load 'remained at a much lower level than peers', so the graph is being monetised deliberately below capacity. On gaming regulation the record is thinner than the received narrative implies: a Hong Kong annual report carries no Risk Factors and no Competition section, and the only place game licensing appears is the Structure Contracts disclosure, where Circular 13 (2009) is discussed as a foreign-ownership question - PRC legal advisers say the arrangement does not violate existing law, while warning of 'substantial uncertainties regarding the interpretation and application' of it. So the disclosed regulatory exposure is structural (VIE legality) rather than an operating constraint on game approvals; the filing simply does not speak to approval throughput at all, and any moat claim resting on it would be unsourced. | Amkor is a back-end contractor; the 10-K says "We provide turnkey packaging and test services including wafer bump, wafer probe, wafer back-grind, package design, packaging, burn-in, system level and final test and drop shipment services." It also says "Our customers include most of the world's largest semiconductor companies." Advanced Products (flip chip, memory and wafer-level packages) were 82.8% of its $6,708M in 2025 net sales. The durable part of its position is scale and a multi-country footprint, which the filing calls "a key differentiator", backed by multi-month customer qualification and customer relationships it dates back "over the last five decades". On Arizona, the filing says: "Construction began in the second half of 2025, and we believe that this investment will strengthen our ability to serve customers seeking to regionalize their supply chains and will enhance our participation in U.S. semiconductor initiatives." Price caps the moat. The 10-K says "We expect downward pressure on average selling prices for our packaging and test services to continue in the future, and this pressure may intensify during downturns in business." It also says foundries "substantially larger than us" have expanded their operations to include packaging and test services. | TSMC is the world's largest dedicated semiconductor foundry and, per its 2025 Form 20-F, the self-described technology leader among dedicated foundries in advanced (7nm-and-below) node revenue, having reached 2-nanometer volume production in 2025 with 16-angstrom risk production on track for 2026. Independent research (Epoch AI) estimates it controls roughly 90% of global advanced-node fabrication; sustained by US$7.9 billion of 2025 R&D, a large patent portfolio and 59.9% gross margins, this process-technology and scale advantage has proven durable even against rivals with greater financial resources. |
| Chain position | Both a downstream AI deployer and an upstream supplier: the report says Tencent Cloud 'achieved profit at scale due to increased enterprise demand for AI workloads' while AI is also credited with improving its own ad targeting and game content production. | Back-end packaging and test step between wafer fabs and chip vendors. The 10-K says "the wafers that we receive from our customers are generally consigned to us", and Amkor serves IDMs, fabless companies, OEMs and contract foundries that outsource packaging and test. | The critical leading-edge fabrication and advanced-packaging (CoWoS) layer of the AI supply chain — high-performance computing was 58% of TSMC's 2025 revenue, and it supplies leading-edge N2/N3/N4 logic to the fabless IC-design and system companies that design AI accelerators. |
