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

Wide: the CUDA software platform and its developer installed base create high switching costs across the AI-training stack, defended by $76.7B cumulative R&D and reinforced by ~71% FY2026 gross margins and Data Center revenue (~90% of total) up 68% YoY — durable, hard-to-replicate advantages per the FY2026 10-K.

narrow

The 10-K states that "the majority of our facilities operate as “merchant” facilities without long-term power sales agreements" and that Vistra is "not guaranteed any rate of return on our capital investments". Against that, the scarcity is real: six NRC-licensed nuclear units totalling 6,448 MW, licences running 2036-2053, inside a 43,641 MW fleet, plus 20-year PPAs with AWS (1,200 MW) and Meta (2,609 MW). The 2025 gas additions - Lotus (2,600 MW, closed October 2025) and pending Cogentrix (5,500 MW) - extend the merchant gas side, not the nuclear scarcity. Only the 433 MW of uprates extends the moat asset.

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.

intangibles ip

The durable edge rests on proprietary IP and software: the full-stack CUDA development platform running on all NVIDIA GPUs plus hundreds of proprietary domain libraries/SDKs/APIs, and $76.7B cumulative R&D yielding "inventions that are essential to modern computing" (NVIDIA invented the GPU in 1999). This is reinforced by developer-ecosystem network effects and CUDA switching costs, per the FY2026 10-K Business section.

source: sec.gov

intangibles ip

The intangibles are non-replicable regulatory assets rather than patents: six nuclear licences (Comanche Peak 2050/2053, Perry 2046, Davis-Besse 2037, Beaver Valley 2036/2047), fuel "contracted to support all our refueling needs through 2030", section 45U credits "recognizing the value of existing carbon-free nuclear power", and TXU Energy, sold "for over 20 years" and "registered and protected by trademark law". Read 45U as a floor, not moat strength: the 2025 credit was $220m against $545m in 2024, and it "provides increasing levels of support as unit revenues decline". Efficient scale does not apply.

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

FY2026 Data Center revenue was $193.7B (~90% of the $215.9B total), up 68% YoY on the Blackwell ramp, and NVIDIA describes itself as "a data center scale AI infrastructure company reshaping all industries." The 10-K frames named rivals as parties who "provide or intend to provide" GPUs/accelerators — incumbent-leader positioning.

source: sec.gov

co leader

Vistra describes itself as "one of the largest producers of power in deregulated markets in the U.S." with over 230 TWh generated, "one of the largest competitive power generators in the U.S. as measured by MWh of generation capacity", "one of the largest electricity generators in the U.S.", and "one of the largest competitive residential retail electricity providers". That hedged phrasing appears four times and is the strongest claim the filing makes. The 10-K names no competitor and assigns no rank, so co-leader is the ceiling the disclosure supports.

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

strong

FY2026 gross margin was 71.1% (75.0% in FY2025); per the 10-K MD&A the ~3.9pt decline reflects the Hopper HGX→Blackwell full-system mix shift and a one-time $4.5B H20 excess-inventory/purchase-obligation charge, not competitive price erosion. A low-70s% hardware gross margin evidences strong pricing power.

source: sec.gov

weak

Vistra is a merchant price taker. Price formation rests on "the highest variable cost unit that clears the market", prices are "unpredictable and may fluctuate substantially", hedging markets have "limited liquidity after two to three years", and competing retailers "may offer different products, lower electricity prices and other incentives". ERCOT's $2,000/MWh figure is the low system-wide offer cap, applied conditionally when the peaker net margin exceeds three times CONE or under the PUCT Emergency Pricing Program, not a standing cap. PJM has "announced that it would propose" extending its capacity cap to 2028-29 and 2029-30, subject to FERC approval.

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.

NVIDIA pairs market-leading accelerated-computing hardware (the Blackwell data-center platform) with a proprietary full-stack software moat — CUDA plus hundreds of domain libraries — funded by $76.7B of cumulative R&D, and its "large and growing number of developers and installed base... strengthens our ecosystem and increases the value of our platform for our customers" (FY2026 10-K). Competition is intensifying from AMD, Intel and Huawei, and from hyperscalers (Alphabet, Amazon, Microsoft) designing internal AI silicon, but rivals must overcome NVIDIA's entrenched CUDA software ecosystem to displace it.

Vistra's moat is one scarce asset wrapped in a commodity business. Six NRC-licensed nuclear units - 6,448 MW, licences running 2036-2053 - sit inside a 43,641 MW fleet that the 10-K says operates in the majority as "merchant" facilities with no long-term power sales agreements and no guaranteed rate of return. That block cannot be rebuilt by a rival, and is now partly de-risked by 20-year PPAs with AWS (1,200 MW from Comanche Peak) and Meta (2,609 MW from the PJM plants) plus section 45U credits. Everything else - 26,989 MW of gas, 8,743 MW of coal, the 5m-customer retail book - competes on price in markets Vistra does not set, against entrants the filing says keep building "despite relatively low power prices". The 2025 growth was gas M&A (Lotus, pending Cogentrix), which widens the commodity-exposed side. Narrow, for a specific reason: the moat is 15% of the fleet.

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.

Upstream compute-platform supplier: NVIDIA sells full-stack data-center systems (GPU + Arm CPU + DPU + NVLink/InfiniBand networking + CUDA software) to cloud providers and enterprises, and relies on third-party foundry/assembly-test-packaging partners (e.g., SPIL, Amkor, Wistron, Fabrinet). Per the FY2026 10-K, several of its largest customers (hyperscalers such as Amazon, Alphabet, Microsoft) are simultaneously customers and emerging competitors developing internal accelerated-computing silicon.

Merchant IPP: sells energy, capacity and ancillary services into ISO/RTO spot and short-term wholesale markets (ERCOT, PJM, ISO-NE, NYISO, CAISO, MISO) and resells to ~5m retail customers. Emerging role as long-term nuclear offtake supplier to hyperscalers (AWS, Meta). Not a price setter at any link.
