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

Iron Mountain's physical-records franchise shows a real switching-cost advantage, but the FY2025 Form 10-K also describes a slowly shrinking need for it, and the growth businesses compete in open markets. On the advantage side, an independent record: the Department of Justice complaint published in the Federal Register on 2016-04-11 (https://www.federalregister.gov/documents/2016/04/11/2016-08210/united-states-v-iron-mountain-inc-and-recall-holdings-ltd-proposed-final-judgment-and-competitive) stated that "Iron Mountain is the largest RMS company in the United States" and that "Taken together, permanent withdrawal fees and other withdrawal restrictions make it difficult for a new RMS entrant to win customers away from existing RMS vendors." The 2025 10-K reports more than 740 million cubic feet stored, says "we have consistently experienced strong customer retention levels", and shows the Global RIM segment's Adjusted EBITDA margin at 44.7% in 2025 against 44.6% in 2024. On the limiting side, Item 1A says "Our Records Management and Data Management service revenue growth is being negatively impacted by declining activity rates as stored records and tapes are becoming less active and more archival" and "A significant shift by our customers to storage of data through non-paper or non-tape-based technologies, whether now existing or developed in the future, could adversely affect our businesses." In data centres the 10-K says it competes with "numerous data center developers, owners and operators, many of whom own properties comparable to ours". A strong, regulator-documented lock-in on a physical market the company itself expects only to hold steady, plus growth arms without that lock-in, is a narrow moat rather than a wide one.

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'.

source: sec.gov

switching costs

The advantage is the cost and friction of moving stored records. The 10-K's Item 1A says that "if we are successful in winning record storage customers from competitors, the process of moving their stored records into our facilities is often costly and time consuming", and its notes record payments made "to a customer in order to terminate the customer's storage of records with its current records management vendor" as customer inducements. The DOJ complaint (https://www.federalregister.gov/documents/2016/04/11/2016-08210/united-states-v-iron-mountain-inc-and-recall-holdings-ltd-proposed-final-judgment-and-competitive) describes the mechanism: "Customer contracts also often impose a cap on the number of boxes per month that a customer may permanently remove from a RMS vendor's facility, such that a switch to a new RMS vendor may take several months to complete", and a new vendor "will have to offer to pay the fees to induce the customer to switch". Scale helps, since the 10-K says "the majority of our competitors operate in only one market or region", but the filing's own account of what keeps customers is retention and the cost of leaving, which makes switching costs the primary source.

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.

source: sec.gov

clear leader

The band applies to records management, the Global RIM segment that produced $5,291,481 thousand of 2025's $6,901,737 thousand revenue. Independent evidence: the DOJ complaint published in the Federal Register on 2016-04-11 (https://www.federalregister.gov/documents/2016/04/11/2016-08210/united-states-v-iron-mountain-inc-and-recall-holdings-ltd-proposed-final-judgment-and-competitive) stated "Iron Mountain is the largest RMS company in the United States", with fiscal 2014 worldwide revenues of "approximately $3.1 billion", and called Recall, with 2014 revenues of "approximately $836.1 million", "the second-largest RMS company in the United States"; the FY2025 10-K lists property "acquired in connection with our acquisition of Recall Holdings Limited". The 2025 10-K adds, in the company's own words, that "the majority of our competitors operate in only one market or region". The independent source is from 2016 and covers the United States only. Iron Mountain did go on to acquire Recall, but the proposed final judgment in the same notice required it to divest "Recall RMS assets in all fifteen geographic markets identified in the Complaint", thirteen of them to Access CIG, which the notice called "currently the third-largest RMS provider in the United States", so Recall's business was not absorbed whole. This leadership does not extend to data centres, where the Global Data Center segment's $803,429 thousand of 2025 revenue compares with total revenue of $9,217,000,000 at Equinix (https://www.sec.gov/Archives/edgar/data/1101239/000110123926000032/0001101239-26-000032-index.htm) and $6,112,692,000 at Digital Realty (https://www.sec.gov/Archives/edgar/data/1297996/000110465926015365/0001104659-26-015365-index.htm) in stored fundamentals from their FY2025 10-Ks.

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%.

source: sec.gov

strong

In records, growth comes from price on steady volume. MD&A attributes Global RIM "organic storage rental revenue growth driven by revenue management" (organic storage rental growth of 5.4% in 2025), while Item 1A says volumes "were relatively steady in 2025" and "Our organic revenue growth has been positively impacted by our ability to effectively introduce, expand and monitor revenue management. If we are not able to continue and effectively manage pricing, our results of operations could be adversely affected". The segment's Adjusted EBITDA margin was 44.7% in 2025 against 44.6% in 2024. In data centres MD&A cites "improved pricing" and "a 620 basis point increase in Adjusted EBITDA Margin reflecting recent lease commencements, improved pricing and cost containment", to 51.8% from 45.6%. The limits: Item 1A says that on power costs "we may be limited in our ability to, or may not always choose to, pass these increased costs on to our customers", and the 2016 DOJ complaint (https://www.federalregister.gov/documents/2016/04/11/2016-08210/united-states-v-iron-mountain-inc-and-recall-holdings-ltd-proposed-final-judgment-and-competitive) found that where Iron Mountain and Recall met, they "competed aggressively against one another for customers, resulting in lower prices for RMS". Adjusted EBITDA margin is a non-GAAP measure, and the Q2 2026 release (https://s204.q4cdn.com/148941814/files/doc_financials/2026/q2/FINAL-Q2-2026-Earnings-Press-Release.pdf) shows it at 35.8% for the company against 36.7% a year earlier.

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.

Iron Mountain stores and manages physical records for, per its FY2025 10-K, more than 240,000 customers in 61 countries, "including approximately 95% of the Fortune 1000", with "no single customer accounting for more than approximately 3% of revenue". Revenue was $6,901,737 thousand in 2025, of which the Global RIM segment contributed $5,291,481 thousand and the Global Data Center segment $803,429 thousand. The records business is the moat. Storage rental agreements "generally range from one to five years in length", the company says it has "consistently experienced strong customer retention levels", and a 2016 Department of Justice complaint described Iron Mountain as "the largest RMS company in the United States" and permanent withdrawal fees as a barrier to rivals winning customers. That lock-in shows up as pricing: MD&A attributes Global RIM storage growth to "revenue management" while Item 1A says volumes "were relatively steady in 2025". The threat is substitution: activity is declining as records become "less active and more archival", and a shift to non-paper storage "could adversely affect our businesses". The growth arms sit outside that moat. The company operated 31 data centers across 21 markets with 488 MW of capacity approximately 97% leased and a weighted average lease expiration of 10.3 years, counts "five of the largest global hyperscalers among our customers", and on 2026-08-05 reported data center leasing of 110 megawatts year to date and second-quarter revenue of $2.0 billion, up 18.5%. But in data centres it competes with operators owning "properties comparable to ours", and in asset lifecycle management with hyperscalers' own programmes. A durable switching-cost franchise in a market expected only to hold steady, funding growth businesses that compete on power, location and price, is a narrow moat.

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.

In the AI build-out Iron Mountain is a landlord and a recycler. It leases data center capacity to hyperscale customers, with "five of the largest global hyperscalers among our customers", and its ALM business "provides hyperscale and corporate IT infrastructure managers with services and solutions that enable the decommissioning, data erasure, processing and disposition, and recycling or sale of IT hardware and component assets". Upstream, Item 1A says "We rely on third parties to provide power to our data centers" and that construction depends on "one or more design firms, general contractors, and associated subcontractors".
