IBM's FY2025 10-K describes "a highly competitive environment" with "hundreds of competitors" and says IBM is "regularly exposed to new competitors" as it executes its hybrid-cloud/AI strategy, while differentiating through "incumbency with enterprises" and "client relationships and trust" — a real but narrow moat, not a wide one.

Ciena's FY2025 10-K describes a technology position that has held but does not lock customers in. On the durable side, the strategy is to "build on and expand our global leadership in optical networking", resting on "our proprietary WaveLogic™ coherent modem technology" and approximately 2,400 issued patents with 800 more pending as of December 2, 2025. On the limiting side, the same filing says competition "remains intense" and features "aggressive selling efforts, including using significant pricing pressure to displace incumbent vendors", that "our customer contracts generally do not include minimum or guaranteed purchases", and that "there is no assurance that we will maintain our incumbency". Concentration cuts the same way: the five largest customers contributed approximately 50% of fiscal 2025 revenue, one cloud provider approximately 18%. Its income statement reports gross profit of $1,878.9M on $4,386.5M of revenue in FY2023, $1,719.6M on $4,015.0M in FY2024 and $2,004.9M on $4,769.5M in FY2025. Self-described leadership in its segments, with customers that are re-won deal by deal, is a narrow moat.

FY2025 10-K (Item 1, Competition; filed 2026-01-23) calls the entertainment-video market 'intensely competitive and subject to rapid change,' with rivals holding exclusive content rights, 'large content libraries, and significant financial, marketing and other resources' and low member switching friction (members 'can change their plans at any time'). The offsetting durable advantage is monetized scale: the Q2 2026 shareholder letter (2026-07-16) guides 2026 revenue to $51.0-$51.4B at a 31.5% operating margin for an audience 'approaching 1B people' — a content budget and margin structure no pure-play streaming rival matches.

Moat type switching costs

The 10-K roots IBM's differentiation in "incumbency with enterprises" and "client relationships and trust" — installed-base lock-in across its hybrid-cloud platform (Red Hat) and enterprise software and infrastructure raises switching costs.

intangibles ip

The FY2025 10-K locates the advantage in owned technology rather than in customer lock-in: "The success of our business and technology leadership depends significantly on our proprietary and internally developed technology." That technology is centred on WaveLogic, which Ciena's fiscal Q3 2026 earnings presentation (the source of the first two product rows below) defines as "Ciena's proprietary family of coherent optical chips — the core technology inside most of our networking products", and it reaches beyond Ciena's own systems: the 10-K's coherent pluggable transceivers use WaveLogic "for use within our systems and third-party equipment". Switching costs are the weaker candidate, because the same filing describes operators disaggregating line systems from modems and competitors using price to displace incumbents.

cost scale

Content and technology spend is amortized across the industry's largest paid streaming membership base: the Q2 2026 shareholder letter (2026-07-16) reports members watched 97B+ hours in H1 2026 for an audience approaching 1B people, with Q2 operating margin of 33% — scale that lets Netflix outspend rivals on programming per subscriber dollar. A secondary intangibles layer sits on top: the FY2025 10-K (Item 1) says Netflix regards its copyrights, trademarks and the original content it produces as 'important to our success.'

Leadership fast follower

An enterprise incumbent that differentiates via "incumbency with enterprises" but is "regularly exposed to new competitors" in its hybrid-cloud/AI push (FY2025 10-K) — a follower in the current AI cycle rather than its leader.

Slide 6 of Ciena's fiscal Q3 2026 earnings presentation of 2026-09-03 (https://s25.q4cdn.com/550667411/files/content_files/Ex-99-2-2026-Q3-Earnings-Presentation_FINAL-1.pdf) lists "#1 in Data Center Interconnect Globally" (Dell'Oro Group), "#1 in Total Optical Networking in N. America" (Cignal AI, Dell'Oro Group, Omdia) and "#1 in Submarine Networks Globally" (Omdia), with market share measured as of Q2 2026 excluding China, and a caveat that Ciena "has not independently verified" the analyst data. On the company's own presentation of that data, that is the front rank in its core segments, but the presentation does not claim the global lead in total optical networking, and the FY2025 10-K says competition is "dominated by a small number of very large, multi-national companies" - Nokia, Huawei, Cisco, Hewlett Packard Enterprise and ZTE - many of which have "substantially greater financial, operational and marketing resources, and broader product offerings". A shared front rank, led by Ciena where the company-reported rankings measure it, rather than an uncontested one.

Nielsen's Media Distributor Gauge for May 2026 (published 2026-07-28): Netflix held 8.0% of total US TV watch-time, the largest of any subscription streamer (Amazon Prime Video 4.5%, Roku Channel 3.1%, Paramount 2.3%); YouTube — an ad-supported, largely user-generated platform — led all distributors at 13.8%.

Pricing power moderate

Gross margin is high and rising (54.9% FY2021 to 58.2% FY2025) on a software-mix shift, but "price" is a principal method of competition per the 10-K and consulting/infrastructure remain price-competitive.

Moderate, and improving. The FY2025 10-K's income statement reports gross profit of $1,878.9M on $4,386.5M, $1,719.6M on $4,015.0M and $2,004.9M on $4,769.5M of revenue for FY2023-FY2025, in a market where, the filing says, rivals use "significant pricing pressure to displace incumbent vendors" and "price and total cost of ownership" heads the list of competitive factors. Since then the AI build-out has lifted gross margin: Ciena's fiscal Q3 2026 earnings presentation (https://s25.q4cdn.com/550667411/files/content_files/Ex-99-2-2026-Q3-Earnings-Presentation_FINAL-1.pdf) reports GAAP gross margin of 45.4% against 41.3% a year earlier, on revenue up 37% year over year, and guides fiscal 2027 adjusted gross margin to 45% to 46%. The presentation does not say how much of that is price rather than mix or volume, and the 10-K warns that AI-related demand has led to "a constrained supply environment" that can raise component costs.

Summary

IBM's moat rests on deep enterprise incumbency — sticky installed-base relationships across hybrid cloud (Red Hat), enterprise software, and mission-critical infrastructure, plus brand and a large patent base. But its own FY2025 10-K frames "a highly competitive environment" with "hundreds of competitors" and says IBM is "regularly exposed to new competitors" as it pursues hybrid cloud and AI, so the moat is durable but narrow and contested in the AI/cloud growth arena.

Ciena is the optical-transport specialist among networking vendors - its fiscal Q3 2026 earnings presentation calls it "the only pure-play optical systems provider operating at scale today" - and its FY2025 10-K builds the business on one proprietary technology, the WaveLogic coherent modem, carried into the 6500 Packet-Optical Platform, Waveserver data center interconnect systems, the 6500 RLS photonic line system and coherent pluggable transceivers sold for Ciena's own systems and third-party equipment. Analyst rankings the company cites in that presentation, which it says it "has not independently verified", put Ciena first in data center interconnect globally, in total optical networking in North America and in submarine networks globally (Q2 2026, excluding China). The AI build-out has turned it into more of a cloud supplier than a telecom one: cloud providers were 53% of fiscal Q3 2026 revenue, revenue rose 37% year over year, and GAAP gross margin reached 45.4%. The 10-K is equally clear about why the position is narrow rather than wide. Competition is "dominated by a small number of very large, multi-national companies", many with greater resources; rivals use pricing to displace incumbents; contracts carry no minimum or guaranteed purchases; the five largest customers were about half of fiscal 2025 revenue; and disaggregation lets an operator buy the line system from one vendor and the modem from another, while the push into data-center interconnects brings Ciena up against Marvell, Credo and Broadcom.

Netflix's advantage is a self-reinforcing scale loop rather than lock-in: the largest paid streaming audience funds the largest content slate, which in turn wins what the 10-K calls 'moments of truth' against every other use of leisure time. The FY2025 10-K is candid that switching costs are low (members can change plans at any time) and that competition spans linear TV, rival streamers, user-generated platforms, gaming and piracy — so the moat is narrow, not wide. What sustains it now is monetization breadth on top of scale: per the Q2 2026 letter, repeated price increases keep landing 'consistent with prior changes and our expectations,' the ads business is on track to roughly double to ~$3B in 2026, live events drove six of the top 10 member sign-up days of the last five years on just over 5% of content spend, and GenAI workflows (used in roughly 300 titles in 2026) are lowering production cost. Nielsen's May 2026 Gauge places Netflix at 8.0% of total US TV time — the largest subscription streamer, though YouTube leads all distributors at 13.8% — which frames the real long-run contest: attention against free, user-generated video, not just against other paid streamers.

Chain position

A hybrid-cloud platform, enterprise-AI (watsonx), and consulting provider to large enterprises — a software/cloud layer of the AI stack.

Ciena sits between optical-component suppliers and the operators building AI-era networks. Upstream, its FY2025 10-K says its products include "optical and electronic components for which reliable, high-volume supply is often available only from sole or limited sources", built by contract manufacturers with facilities in Canada, Mexico, Thailand, Vietnam and the United States; at November 1, 2025 it carried $826.2 million of inventory and $2.1 billion of purchase commitments. Downstream, the fiscal Q3 2026 earnings presentation puts direct cloud providers at 53% of the quarter's revenue against 37% for service providers, and describes its products as the links between data centers (data center interconnect) and between distributed AI training clusters ("scale-across").

Consumer-facing distributor at the end of the entertainment supply chain: the FY2025 10-K (Item 1) says revenues are 'primarily derived from monthly membership fees,' and Netflix competes two ways — downstream for viewers' leisure time and upstream 'against entertainment video providers and content producers in obtaining content,' both licensed and original; the ads tier adds a second monetization rail on the same distribution asset.
