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.
| Cloudflare | Constellation Energy | ChipMOS Technologies | |
|---|---|---|---|
| Moat rating | wide The band is earned by a measured share gap on a hard-to-rebuild asset, not asserted. W3Techs' 17 September 2026 survey (w3techs.com/technologies/overview/proxy) puts Cloudflare in front of 25.8% of all websites, an 85.0% share of the reverse-proxy market, against Amazon CloudFront at 5.5%, Fastly at 3.0% and Akamai at 2.1% - roughly fifteen times the nearest rival. The FY2025 10-K filed 2026-02-26 describes what a challenger would have to reproduce to contest that: a network that 'spans more than 330 cities in over 125 countries worldwide and interconnects with over 13,000 networks globally', architected to 'run every service on every server in every city' - capacity and peering accumulated city by city over a decade, not bought in a quarter. The position has been monetised without margin decay: SEC XBRL fundamentals on this site show GAAP gross margin inside a 74.5-78.7% band in every fiscal year from FY2017 to FY2025 while revenue grew from $134.9M to $2,167.9M, and Cloudflare's Q4/FY2025 results release of 2026-02-10 (cloudflare.com/press/press-releases/2026/cloudflare-announces-fourth-quarter-and-fiscal-year-2025-financial-results/) reports remaining performance obligations up 48% and new annual contract value up nearly 50% year over year. What stops this being a certainty rather than a judgement: the dominant share sits in application services, while SASE and developer compute are contested by vendors the 10-K itself concedes hold 'substantially greater financial, technical, and other resources.' | wide The FY2025 10-K describes the nation's largest nuclear fleet — approximately 22 GW across 14 stations producing 68% of 2025 electric supply — running at a 94.7% capacity factor that 'has been approximately four percentage points better than the industry average annually since 2013', with NRC licences extending to 2054 and an IRA nuclear production tax credit floor from 2024. | none ChipMOS earns thin returns in businesses its own 20-F describes as price-driven. The FY2025 20-F reports gross margin of 10.8% in 2025, against 13.0% in 2024. Profit attributable to equity holders was NT$551 million, against NT$1,440 million in 2024 and NT$1,968 million in 2023. The display driver business, 24.5% of 2025 revenue, saw its gross margin fall to 7.5% from 22.5%, which the filing attributes to 'the decline of average selling price'. Its revenue fell 20% on customer inventory adjustments and 'the price competition among DDIC suppliers in Mainland China'. Assembly services ran at a -1.6% gross margin. The filing says prices for its services 'tend to decline over the course of its product and technology life cycle'. Results improved in the 2026 memory upturn: the 2Q26 press release reports an 18% gross margin and the 2Q26 call reports a 14.4% return on equity. One strong quarter in a memory upturn does not offset profits that fell in both 2024 and 2025, so the rating is none. |
| Moat type | cost scale The FY2025 10-K states the mechanism outright, and it is a unit-cost curve rather than a user-to-user network: 'We have chosen to utilize this idle capacity to create a free tier of service which has generated substantial global scale for us. In turn, this scale makes us attractive partners for Internet Service Providers (ISPs) globally, which reduces our co-location and bandwidth costs. As our network grows, these dynamics become even more powerful.' The same section explains why the curve applies to every line rather than one: the architecture lets Cloudflare 'deploy standard, commodity hardware' and run 'every service on every server in every city', so a new product reaches 330+ cities at near-zero incremental capital. That is what lets the filing claim Workers is offered 'at prices that are highly competitive with public cloud vendors' while FY2025 GAAP gross margin still printed 74.5%. Switching costs (traffic routed through Cloudflare, DNS delegated to it) and threat-intelligence feedback from aggregate traffic sit on top, but the filing-stated primary source is cost falling as the network grows. | cost scale The cited edge is operating cost at scale: average refuelling outages of 22 days in 2025 against industry averages of 33 and 38 days in 2024 and 2023, a capacity factor about four points above the industry every year since 2013, and 'significant economies of scale' in what the filing calls the largest US customer-facing energy platform. | none None of the moat sources is supported. Switching costs are low: the 20-F says customer qualification 'typically takes up to eight weeks', that test correlation 'typically takes up to two weeks', and that most customers buy through purchase orders with 'three-month non-binding rolling forecasts'. Scale sits elsewhere: TrendForce's 2024 ranking (2025-05-13) places ChipMOS tenth among OSATs at $710M, against $2.28B for Powertech, which TrendForce (2026-01-12) calls the world's leading DRAM and NAND test and packaging provider. IP is not decisive: the 20-F lists the measures of competitiveness in testing as software engineering, quality of service, flexibility, capacity, production cycle time and price. It names ASE, Amkor, Chipbond, KYEC, Powertech, JCET and UTAC as competitors, alongside IDMs with in-house capacity. |
| Leadership | clear leader Leadership is measured, not inferred. W3Techs on 2026-09-17 records an 85.0% reverse-proxy market share against 5.5% for Amazon CloudFront and 2.1% for Akamai, and makes Cloudflare the largest authoritative-DNS provider at 18.5% of all websites versus 9.9% for the next-placed GoDaddy Group. The FY2025 10-K reports the enterprise side moving the same way - 4,298 large customers at 2025 year-end against 3,497 a year earlier and 2,756 in 2023 - and the Q4/FY2025 results release (cloudflare.com/press/press-releases/2026/cloudflare-announces-fourth-quarter-and-fiscal-year-2025-financial-results/) cites the largest annual contract value deal in company history at about $42.5M per year. The band is for the application-services core the share data covers; in SASE and in serverless compute Cloudflare is a challenger to larger incumbents, and no independent placement naming Cloudflare in those markets was obtained for this profile. | clear leader The 10-K states Constellation is 'the largest nuclear energy company in the U.S.', is 'the nation's largest energy supplier for C&I and residential power volumes' based on EEI data, and has 'over 32% of the C&I market share of direct customer business'. | at parity TrendForce's 2024 ranking (2025-05-13) places ChipMOS tenth among global OSATs with $710M in revenue, and credits its driver IC business with 'steady demand in the automotive and OLED sectors'. Powertech's 2025 annual report, compiled from Taiwan's Market Observation Post System, shows ChipMOS revenue of NT$23,933 million in 2025, against NT$21,454 million for Chipbond, a competitor the 20-F names, and NT$74,929 million for Powertech. The 20-F calls ChipMOS 'one of the leading independent providers' of display driver and memory testing and assembly in Taiwan, which is its own description. No source shows a lead over peers, so the band is at_parity. |
| Pricing power | moderate Evidence cuts both ways, which is why this is not the top band. For it: GAAP gross margin has never left a 74.5-78.7% band across FY2017-FY2025 (SEC XBRL fundamentals on this site) even as revenue compounded 16x, and the Q4/FY2025 results release (cloudflare.com/press/press-releases/2026/cloudflare-announces-fourth-quarter-and-fiscal-year-2025-financial-results/) shows customers committing more rather than less - RPO +48% year over year and new ACV up nearly 50%. Against it: FY2025's 74.5% is the lowest reading in that nine-year series, a large permanent free tier anchors the entry price, the 10-K positions Workers 'at prices that are highly competitive with public cloud vendors', and the competition risk factor warns that larger rivals can 'sell products and services with which we compete at zero or negative margins, offer fee waivers and reductions or other economic and non-economic concessions', with competitive pressure that 'may result in price reductions, fewer subscriptions, reduced revenue and gross margin'. | moderate The 10-K states 'While providing customers with a competitive price is a key focus' in retail, on roughly two-year average C&I contract terms with 77% power and 84% gas renewal rates in 2025, and the nuclear fleet's downside is set by the IRA nuclear PTC 'as unit revenues decline below levels established in the IRA'; SEC-reported operating income was 13.6% of revenue in 2025. | weak The 20-F says its service fees 'tend to decline in tandem with the declining average selling prices of the products we test and assemble'. It says memory fees 'were sharply reduced in tandem with' falling DRAM and flash prices in the past. Display driver gross margin fell to 7.5% from 22.5% in 2025 on falling selling prices. In the 2026 upturn the company is passing costs through: on the 2Q26 call the chairman said rising costs for substrates, lead frames and gold will be passed on to customers, and gross margin reached 18.0%. That is cost recovery in a tight market, not durable pricing power. |
| Summary | Cloudflare sells security, performance and connectivity as services delivered from one global anycast network rather than from boxes at a customer's edge. The FY2025 10-K frames the market as a consolidation away from enterprises that 'string together a diverse set of on-premises hardware boxes from different vendors' and away from 'stringing together multiple point-cloud solutions that only address specific network needs', toward one integrated provider it calls the Connectivity Cloud, and places Cloudflare as 'a leader in this Connectivity Cloud category'. The economics are unusual: idle capacity funds a free tier, the free tier buys global traffic scale, that scale makes Cloudflare a peering partner ISPs want, and peering cuts colocation and bandwidth cost - a loop the filing says 'become[s] even more powerful' as the network grows. Independent measurement confirms where that loop has already settled the market: W3Techs on 2026-09-17 shows an 85.0% reverse-proxy share and the largest authoritative-DNS footprint at 18.5% of all websites. Commercially the company ended 2025 with roughly 332,000 paying customers in more than 190 countries and 4,298 large customers, up from 2,756 two years earlier, with no customer above 10% of revenue. The contested half of the story is the growth half: the SASE platform competes with established cloud-security, email-security and SD-WAN vendors, and the developer platform competes for storage and compute against hyperscalers, markets where the 10-K's own risk factors concede rivals have greater name recognition, larger customer bases and 'more mature products and services developed for large customers'. The core is defended; the adjacencies are being fought for, and FY2025 gross margin at a nine-year low of 74.5% is the first visible cost of building GPU capacity for that fight. | Constellation pairs the largest US nuclear fleet with the largest competitive retail book, which lets it sell around-the-clock carbon-free power under long-term contracts such as the 20-year Microsoft PPA restarting Three Mile Island Unit 1 as the 835 MW Crane Clean Energy Center. | ChipMOS is a Taiwanese outsourced assembly and test house (OSAT) with plants in Hsinchu and Tainan. In 2025, memory and logic/mixed-signal testing was 23.7% of revenue, assembly 28.6%, display driver assembly and test 24.5% and bumping 23.2%. Its top five customers took 61% of revenue, and its top fifteen include Micron, Novatek, Himax, Nanya, Winbond, Macronix and MediaTek. The memory upturn has shifted the mix. On the 2Q26 call, memory was 51% of revenue and display drivers 18.1%, overall utilization was 72%, and management said it 'selectively raised the memory OSAT price' to reflect material costs. 2Q26 revenue of NT$7,383.1 million was the highest since 2014. TrendForce (2026-01-12) cites analysts saying that DRAM, 'led by DDR4, which makes up roughly 70–80% of memory sales', remains the company's 'core earnings driver'. Management is reallocating capacity. It signed a three-year memory wafer test take-or-pay contract in early 2026, it is 'monetizing the low-end and lower UT level DDIC assets', and it plans to add testing capacity for AI ASICs and silicon photonics. The verdict is no moat: a capable mid-sized OSAT whose margins follow memory prices and Chinese display-driver competition. |
| Chain position | Cloudflare sits between end users and whatever hosts the application - origin data centre, public cloud or SaaS - so it is a control layer in front of infrastructure rather than infrastructure a workload runs on, which the 10-K argues is the point: customers 'concerned about being locked in to any one public cloud provider' want policy enforced by 'an independent and integrated services provider'. Two AI-era roles follow from that position. As a supplier, the filing describes 'ongoing deployment of graphics processing units (GPUs) across our global network of servers' behind Workers AI, Vectorize and AI Gateway, putting inference next to the user instead of in a region. As a gatekeeper, the application-services suite now exists in part to 'easily identify, block and control access from AI crawlers and AI agents and operators' and underpins announced efforts to let content creators monetise how those crawlers reach their work - which makes Cloudflare a toll point between AI model builders and the open web. | Generator and retailer in one — the fleet is the physical supply behind the long-term carbon-free contracts it sells to large corporate buyers. | Back-end assembly and test supplier to memory makers and display-driver designers. Customers headquartered in Taiwan were 87% of 2025 revenue, per the 20-F. |
