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

Jabil's FY2025 10-K (fiscal year ended August 31, 2025) says it plainly: "Our business is highly competitive, and our manufacturing processes are generally not subject to significant proprietary protection." It adds that "The significant purchasing power and market power of these competitors, many of which are large companies, has and could increase pricing and competitive pressures for us", that some "have substantially greater manufacturing, research and development (R&D) and marketing resources", and that customers "are continually evaluating the merits of manufacturing products internally against the advantages of outsourcing". Stored fundamentals from the 10-Ks show gross profit of $2,867 million on $34,702 million of revenue in fiscal 2023, $2,676 million on $28,883 million in fiscal 2024 and $2,646 million on $29,802 million in fiscal 2025. AI demand has since accelerated growth (fiscal 2026 net revenue of $36.0 billion, per the 2026-09-30 release), but growth is not protection, and the filing's own description is of an unprotected, competitive service. No moat is claimable.

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

The 10-K says "We currently have a relatively modest number of patents for various innovations" and that Jabil relies "largely upon a combination of intellectual property laws, non-disclosure agreements with our customers, employees, and suppliers and our internal security systems, policies, and procedures", with other proprietary-rights factors being "the knowledge and experience of our management and workforce". Its stated advantages are operating methods (customer-dedicated business units, "highly automated, continuous flow manufacturing", global production and centralized procurement), not lock-in: "In the past, some of our customers moved a portion of their manufacturing from us in order to more fully utilize their excess internal manufacturing capacity." On the Q4 FY2026 call (https://earningswhispers.com/transcript/JBL/Q42026) management described a build-to-customer-design model rather than proprietary platforms: "We help customers build the system they've designed with their silicon, their architecture, and whichever suppliers they choose."

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'.

source: sec.gov

at parity

The 10-K calls Jabil "one of the leading providers of engineering, manufacturing, and supply chain solutions" and claims no rank. Independently, EMSNOW/in4ma's "EMS&ODM Global 100" (2026-03-06, https://www.emsnow.com/?p=53535) groups Jabil with Flex, Celestica and Sanmina as the US "big four", "representing about 85% of the revenue base among ~20 US headquartered EMS/ODM", while Wistron, Quanta and Wiwynn "plus Foxconn together account for nearly 57% of global EMS/ODM production". The 10-K concedes some competitors have "substantially greater manufacturing, research and development (R&D) and marketing resources". Among the largest Western contract manufacturers but behind the Taiwanese leaders in scale: at parity, not a 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'.

source: sec.gov

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

Stored fundamentals show gross profit of $2,867 million on $34,702 million of revenue in fiscal 2023, $2,676 million on $28,883 million in fiscal 2024 and $2,646 million on $29,802 million in fiscal 2025. The 10-K says "Most of our significant long-term customer contracts permit quarterly or other periodic prospective adjustments to pricing based on decreases and increases in component prices and other factors", so component costs largely pass through, while competitors may "be better positioned to compete on price for their services". Management's fiscal 2027 outlook is a core operating margin (non-GAAP) of 6.1% (release, https://www.sec.gov/Archives/edgar/data/898293/000162828026063890/jbl-20260930ex991.htm).

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.

Jabil provides engineering, manufacturing and supply chain services through three segments. Per its FY2025 10-K, Intelligent Infrastructure serves "capital equipment, cloud and data center infrastructure, and networking and communications" customers; Regulated Industries serves automotive and transportation, healthcare and packaging, and renewables and energy infrastructure; and Connected Living and Digital Commerce is focused on "digitalization and automation, including warehouse automation and robotics". AI demand now drives growth: the fiscal 2026 release (2026-09-30) reports net revenue of $36.0 billion, with the CEO saying Jabil "grew revenue 21%, expanded core operating margin 40 basis points", and on the Q4 FY2026 call management said "AI-related revenue was up 60% year-over-year", that Jabil "ended the year with four customers with AI related revenue above a billion dollars annually", and that it expects cloud and data center infrastructure revenue of "approximately $17.5 billion" in fiscal 2027. The 10-K shows the limits: the five largest customers were approximately 36% of fiscal 2025 revenue and one customer, reported primarily in Intelligent Infrastructure, 16%; manufacturing processes are "generally not subject to significant proprietary protection"; and competitors may "be willing or able to make sales or provide services at lower margins than we do". An independent tally (EMSNOW/in4ma, 2026-03-06) counts Jabil among the US "big four" EMS providers while putting Foxconn, Wistron, Quanta and Wiwynn at "nearly 57% of global EMS/ODM production". A large, fast-growing contractor without a protected position.

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.

Contract manufacturer for cloud, networking, semiconductor-equipment, automotive, healthcare and consumer customers. On the Q4 FY2026 call management said "Others in the industry are building product companies around their own power and cooling platforms and asking customers to standardize on them. That's a legitimate model. Ours is different."
