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 | Microsoft | Tower Semiconductor | |
|---|---|---|---|
| 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 FY2026 10-K (filed 2026-07-29) restates both structural mechanisms verbatim. On cost: the cloud business 'benefits from three economies of scale' — datacenters with 'significantly lower cost per unit than smaller ones', demand aggregation, and multi-tenancy that lowers maintenance labor. On ecosystem: 'A well-established ecosystem creates beneficial network effects among users, application developers, and the platform provider that can accelerate growth.' Both are load-bearing at the new scale — 'Microsoft Cloud revenue increased 27% to $214.4 billion' and 'Commercial remaining performance obligation increased 84% to $678 billion.' Rated wide but held below full confidence because the same filing still cautions that 'Barriers to entry in many of our businesses are low.' | narrow Customers are paying in advance for Tower's silicon photonics capacity. On 2026-05-13 Tower announced SiPho contracts 'for $1.3 billion for 2027 revenue with its largest customers' and 'the receipt of $290 million in customers' prepayments for capacity reservation', backed by 'an even larger contractual wafer commitment for 2028'. The Q2 2026 balance sheet shows long-term customers' advances of $145,368 thousand at June 30, 2026, against $1,932 thousand at December 31, 2025. TrendForce's 2Q26 ranking (2026-09-09) attributes Tower's 11.2% QoQ growth to 'ICs used in AI optical transceiver modules, including TIAs/drivers, and photonic ICs'. Profits are rising: Q2 2026 gross profit was $138 million on $460 million of revenue, against $80 million on $372 million a year earlier. The moat is narrow, not wide. It covers one fast-growing platform. Tower's overall foundry share was 0.8% in 1Q26 (TrendForce, 2026-06-12), and TrendForce (2026-07-30) reports that TSMC, UMC and GlobalFoundries are all investing to compete in silicon photonics. |
| 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. | network effects The FY2026 10-K keeps the ecosystem passage scoped to the firm: 'An important element of our business model has been to create platform-based ecosystems on which many participants can build diverse solutions. A well-established ecosystem creates beneficial network effects among users, application developers, and the platform provider that can accelerate growth.' That remains the one moat mechanism the filing asserts about Microsoft as a whole; the cost-of-scale passage stays scoped to 'our cloud business'. | intangibles ip The moat comes from process technology: the SiPho and SiGe platforms that customers prepay to secure. In the May 2026 release, the CEO says the commitments reflect customers' confidence in Tower's 'differentiated, multi-generational silicon photonics technology roadmap'. Those are the company's own words. An outside view comes from a Chinese trade outlet. Its article, republished by 36Kr on 2026-03-02, says 'Tower is not only the absolute supplier of 1.6T PICs but also the main producer of core components such as drivers, TIAs, and PDs'. It adds that in the 1.6T era success depends on 'repeatable manufacturing, predictable yield, and large-scale supply capacity', which it calls Tower's core value. The same article quotes Tower's CEO claiming 'a leading position in the industry' in SiGe and SiPho, so the outlet partly echoes the company. The know-how is contestable. TrendForce (2026-07-30) reports that TSMC's COUPE platform 'has entered mass production'. UMC has delivered its first mass-produced silicon photonics wafers and plans its own 12-inch platform in 2027. GlobalFoundries bought the SiPho foundry AMF in 2025. Tower's Q2 2026 release also lists patent infringement claims brought against it by GlobalFoundries. |
| 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. | co leader The FY2026 10-K asserts leadership nowhere. Its AI offerings 'compete with AI products from hyperscalers, as well as products from other emerging competitors and other open-source offerings, many of which are also current or potential partners' — one of a small set at hyperscale in cloud and AI, an incumbent in productivity and PC operating systems. | co leader Tower leads in silicon photonics but not in foundry overall. TrendForce ranks it seventh in both 1Q26, with a 0.8% share, and 2Q26, with $460 million of revenue. That is well behind GlobalFoundries at about $1.79 billion, which TrendForce says also grew on 'power ICs and TIAs/drivers'. In silicon photonics, the 36Kr article (2026-03-02) calls Tower 'the absolute supplier of 1.6T PICs', but the same article calls GlobalFoundries, after its AMF acquisition, 'the world's largest pure-play silicon photonic chip foundry in terms of revenue'. TrendForce (2026-07-30) names it alongside TSMC, UMC and GlobalFoundries as foundries 'making deep investments in the sector'. Tower calls itself 'the leading foundry of high-value analog semiconductor solutions'. No tracker share confirms that, so the band is co-leader, not clear leader. |
| 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'. | strong The FY2026 10-K reports 'Gross margin increased $31.6 billion or 16% with growth across each of our segments', with 'Microsoft 365 Commercial revenue ... mainly affected by a combination of continued installed base growth and average revenue per user expansion'. The honest caveat: gross margin percentage 'decreased slightly driven by continued investments in AI infrastructure and growing AI product usage', with Microsoft Cloud gross margin down to 66%. | moderate Margins are improving, and SiPho customers are paying for capacity in advance. Q2 2026 gross profit was $138 million on $460 million of revenue, against $80 million on $372 million in Q2 2025. In MarketBeat's transcript of the Q2 2026 call, management put the gross margin at 30%. Q1 2026 operating cash flow of $510 million included a $285 million net increase in customers' advances, per the Q2 2026 release. The rest of the business is less tight. On the same call, management said the 200mm fabs ran at 80% to 85% utilization, while Fab 7 in Japan was fully utilized. No disclosed wafer price increase was found. |
| 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. | One repeated model across segments — build a platform, attract developers and partners, monetize the ecosystem that forms — now compounding through the AI wave: FY2026 revenue rose 18 percent 'driven by growth in Microsoft Cloud', Azure and other cloud services grew 41 percent, and the commercial remaining performance obligation reached $678 billion, while the filing still concedes low barriers to entry in many businesses. | Tower Semiconductor is a specialty analog foundry. It owns one 200mm fab in Israel and two 200mm fabs in the U.S. It holds two Japanese fabs (200mm and 300mm) through its 51% stake in TPSCo, and shares a 300mm facility in Agrate, Italy with STMicroelectronics. Its platforms include SiPho, SiGe, BiCMOS, RF CMOS, CMOS image sensors, power management (BCD and 700V) and MEMS. Q2 2026 revenue was a record $460 million, up 24% YoY, with net profit of $91 million, and Q3 guidance is $520 million. Silicon photonics drives the growth. The Q2 2026 release puts SiPho at a $680 million annual run rate, up from $180 million a year earlier, and the company plans to cross a $1 billion run rate in Q4 2026. Tower raised its 2028 target to $3.6 billion of revenue with $1.2 billion of net profit, which it says is 'fully spoken for by our customers'; that is a company target, not a result. TrendForce (2026-02-13) relays Tower's statement that its SiPho technology will underpin 1.6T optical modules built to support NVIDIA's networking standards. Capacity is the constraint. TrendForce (2026-07-30) says Tower plans to convert its Arai facility in Japan into a 12-inch silicon photonics and advanced packaging platform, expand Fab 7 in Uozu, and prepare a new 12-inch fab. Tower disclosed that Intel intends to withdraw from a 2023 agreement to make 300mm wafers for Tower's clients in New Mexico; the companies entered mediation, and those volumes were rerouted to Fab 7 (TrendForce, 2026-02-13). The verdict is a narrow technology moat in silicon photonics, proven by customer prepayments. It is narrow because it covers one platform in a mostly mature analog business, and larger foundries are entering that platform. |
| 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. | Hyperscale AI-infrastructure buyer and platform distributor: monetizes upstream compute through Azure, Microsoft 365 Copilot, and the developer ecosystem. | Upstream specialty foundry for optical-transceiver, RF, power-management and image-sensor chip companies. Its SiPho photonic ICs and SiGe TIAs and drivers go into AI datacenter optical modules. |
