Moat rating narrow

Wide is ruled out by the company's own Item 1A, which concedes "low switching costs" and that "Low barriers to entry allow start-up companies with lower costs and less pressure for profitability to compete with us." It sits well above none because Q4 DAUs grew 30% to 52.7M, DAU/MAU rose to 39.6% from 34.7%, and marketing took only 12% of FY2025 revenue, though that ratio was flat versus FY2024 and gross margin fell to 72.2% from 72.8%. It stays narrow rather than eroding because Q1 FY2026 DAUs and paid subscribers each grew 21%.

narrow

The FY2025 10-K's own competitive record cuts both ways. Item 1 says a "high-quality, highly interconnected global portfolio such as ours could not be easily replicated today on a cost-competitive basis," yet Item 1A concedes that competitors have "significantly greater financial, marketing and other resources and more ready access to capital" and that as rivals keep developing space, "rental rates may be reduced or we may face delays in leasing." A durable advantage that its own filing says new supply can price against is bounded, not unassailable.

narrow

The FY2025 10-K's own Competition section says the markets for Adobe's solutions are characterized by 'limited barriers to entry, short product lifecycles, customer price sensitivity ... and the frequent entry of new solutions or competitors', and Item 1A adds that Adobe 'face[s] increasing competition from companies offering generative and agentic AI solutions, including but not limited to prompt-based and multi-modal creation and editing, document productivity and understanding' - the two categories that carry the Digital Media segment. That disclosed contestability caps the moat below wide, while the same filing's industry-standard app designations and 89% consolidated gross margin keep it well above none.

Moat type intangibles ip

The intangible is the consumer brand, not patents: Item 1 says "For many, Duolingo has become synonymous with language learning" and that growth is "organic, primarily driven by word-of-mouth and brand buzz," while the IP section discloses only "two patent applications." Switching costs are ruled out by the filing's own "low switching costs" caption. The data-scale support is the filing's own characterisation, and the brand is admittedly damageable: an April 2025 AI memo "may have contributed to unfavorable publicity, adverse impacts on the Company's brand and social media presence, and a deceleration in user growth."

network effects

Item 1 attributes the hard-to-replicate part of the portfolio to connectivity rather than to real estate: "the network density, interconnection infrastructure and connectivity-centric customers in certain of our data centers have led to the organic formation of densely connected data communities that are difficult for competitors to replicate." That community sits on over 232,000 cross connects in over 55 metros, so each network and cloud that lands makes the same building worth more to the next tenant.

switching costs

The 10-K frames Adobe's differentiation as an integrated ecosystem the customer's work lives inside: Creative Cloud Pro subscribers get 'cloud storage to easily sync, access, collaborate and share their work, files and assets', the AI platform offers a choice of models 'without the friction of switching between workflows and platforms', and on the enterprise side 'Our competitive differentiation comes from the increased value we provide customers by integrating the Adobe Experience Platform with our comprehensive set of solutions'. 96% of FY2025 revenue is subscription, with $22.52B of remaining performance obligations, up 13% year over year.

Leadership clear leader

Leadership holds within consumer app-based language learning, anchored on one externally checkable claim in Item 1: the app "is also the top-grossing app globally in the Education category on both Google Play and the Apple App Store," with "over 250 total language courses to more than 130 million monthly active users" as of 2025-12-31. The broader "leading market position" claim is the filing's own characterisation, and no third-party share statistic appears anywhere in the 10-K, so a band is recorded and no percentage transcribed. The band does not extend to assessment, literacy, math, music, chess or offline learning, where the filing claims no position.

co leader

Item 1 claims the title of "the largest global provider of cloud- and carrier-neutral data center, colocation and interconnection solutions," but the Competition section names Equinix and NTT as operators of properties "similar to ours in some of the same metropolitan areas," plus Global Switch and regional operators abroad — a shared top tier on the company's own telling, not a solitary one.

clear leader

In the segment that is 74% of FY2025 revenue ($17.65B of $23.77B) the 10-K asserts leadership outright: Illustrator 'our industry-standard vector graphics app', After Effects 'our industry-standard motion graphics and visual effects app', Acrobat 'a leading document productivity app', and 'category and brand leadership' in the Competition section. The claim does not extend to the whole company - the same section says the marketing solutions 'face broad competition from large, established enterprise software and cloud companies'.

Pricing power weak

Every mechanism is cost, mix or volume, never price. FY2025 gross margin fell to 72.2% from 72.8% on "increased AI costs used in features like Video Call" and an advertising mix shift; the Q1 FY2026 gain to 73.0% came from "continued reductions in per-unit AI costs," with margin guided to about 71.0% in Q2 and "approximately 69.0% by Q4." The filing concedes it "may not be able to fully offset such higher costs through price increases." Subscription revenue rose 44% to $873.4 million "primarily due to an increase in the average number of paid subscribers," and the cap is self-imposed: "We intentionally do not put our learning content behind a paywall."

strong

FY2025 renewals signed re-priced upward in every bucket — +27.0% on greater-than-1 MW space ($146 to $186 per square foot), +4.6% on 0-1 MW ($268 to $280) and +43.0% on other ($49 to $71) — and MD&A expects average aggregate rental rates on 2026 renewals to be positive against the rates currently paid for the same space "on a GAAP basis and on a cash basis." On costs, the filing says utilities expense "is our largest expense category" and that "the vast majority of the expense is passed directly through to our customers," which it credits with significantly mitigating exposure to power-cost increases rather than removing it. The cap: Item 1A warns competitor development could still force rates down.

strong

Per the same 10-K's segment table, Digital Media earned a 95% gross profit margin in FY2025 (96% FY2024, 95% FY2023) and consolidated gross margin held at 88%/89%/89% across FY2023-FY2025 while revenue grew 11% to $23.77B. 96% of revenue is subscription and remaining performance obligations reached $22.52B, up 13%. Item 1A's warning of 'downward pressure on pricing and gross margins' has not shown up in realized margin.

Summary

Duolingo's moat is essentially one asset — a consumer brand strong enough that the filing claims people "search for the term 'Duolingo' much more often than 'learn Spanish'" — sitting on real but not defensive scale. It converts into economics through organic acquisition: sales and marketing took 12% of FY2025 revenue while Q4 DAUs grew 30% to 52.7 million and DAU/MAU rose to 39.6% from 34.7%. It is not wide, because the company supplies both disqualifiers itself: "low switching costs" and "Low barriers to entry allow start-up companies with lower costs and less pressure for profitability to compete with us." Width and pricing power diverge: Duolingo will not price against its own free product, grows subscription revenue by adding subscribers ($873.4 million, up 44%), and guides gross margin down to roughly 69% by Q4 FY2026 "as AI feature use expands in our products."

Digital Realty rents space, power and connectivity rather than compute: at 2025 year-end its portfolio held 310 data centers and roughly 57.6 million rentable square feet across more than 55 metros in over 30 countries, about 84.7% leased, serving more than 5,000 customers. Two different businesses sit inside that footprint. The greater-than-1 MW wholesale side is a capital-and-power race — 769 MW of projects underway with 64% pre-leased, and land that "could accommodate over 3,500 megawatts of additional data center capacity" — where the 10-K names Equinix, NTT, Global Switch and "various private operators" as rivals and warns that added supply can push rents down. The colocation and interconnection side is the defended half: over 232,000 cross connects and the "densely connected data communities" Item 1 says competitors cannot easily replicate, reinforced by contracts the filing describes as generally running 5-10+ years on large deployments and by improvements "installed at our customers' expense." FY2025 leasing supports that read — renewals signed re-priced +27.0% on greater-than-1 MW space and +4.6% on 0-1 MW — while customer concentration is the offsetting exposure, with the largest customer at roughly 11.7% of annualized recurring revenue.

Adobe's durable advantage is the cost of leaving rather than any disclosed market share. Its FY2025 10-K calls Illustrator 'our industry-standard vector graphics app' and After Effects 'our industry-standard motion graphics and visual effects app', describes Acrobat as 'a leading document productivity app', and sells them as one subscription ecosystem where assets, workflows and collaboration are cloud-resident. The economics follow: Digital Media earned a 95% gross profit margin on $17.65B of FY2025 revenue, 74% of the company. The same filing is unusually candid about the limits, calling its markets characterized by 'limited barriers to entry' and warning that competition will 'continue to intensify' with named generative and agentic AI entrants in both creation and document productivity - so the moat reads narrow rather than wide, held today by realized pricing and switching costs rather than by structural protection.

Chain position

A consumer AI application and net buyer of model inference. The filing ties its margin line directly to inference cost, attributing the FY2025 subscription gross-margin decline to "increased AI costs used in features like Video Call" and guiding margin to approximately 69.0% by Q4 FY2026 "as AI feature use expands," while the Q1 FY2026 beat came from "reductions in per-unit AI costs."

Landlord to the AI stack — sells the space, power and interconnection that cloud, network and enterprise tenants run compute in (Oracle, IBM, Meta Platforms, AT&T, Comcast and Lumen are among the customers named in Item 1), with roughly 2.9 GW of total in-place IT capacity.

An AI-application layer company that both builds its own commercially safe Firefly foundation models and licenses 'an extensive ecosystem of third-party models', distributing generative AI into creative, document and marketing workflows.
