Netflix: From Streaming Pioneer to Advertising Powerhouse

The Streaming Wars Are Over. Netflix Won.

We need to say something that most analysts are still too cautious to state plainly. The streaming wars are over. Netflix won. Not in the dramatic, winner-take-all sense that the phrase implies — Disney+, Amazon Prime Video, and YouTube will continue to exist and command significant viewership — but in the only sense that matters to investors: Netflix is the only pure-play streaming company that has figured out how to generate enormous profits at global scale. Everyone else is either subsidizing their streaming business through other segments (Amazon, Apple) or still clawing toward profitability (Disney, Paramount before its sale to Skydance).

The numbers tell the story. Netflix generated $39 billion in revenue and $10.9 billion in operating income during 2025, producing a 28.1% operating margin that would have seemed delusional to predict three years ago when the stock was trading at $170 and the narrative was “streaming is an unprofitable race to the bottom.” Free cash flow exceeded $8 billion. The content library spans 190+ countries in 30+ languages. And the subscriber base — 302 million paid memberships as of Q4 2025 — gives Netflix a demand density that no competitor can match.

Here is the contrarian part. We think the market still undervalues Netflix. Not because the stock is cheap on traditional metrics (it trades at 35–38x NTM P/E, which is objectively expensive), but because the market is pricing Netflix as a mature subscription business when it is actually in the early innings of becoming an advertising platform. That distinction matters enormously, because advertising revenue carries incremental margins north of 60% and has a longer growth runway than subscription revenue in a market approaching saturation.

From Cash Incinerator to Cash Machine

Rewind to 2019. Netflix burned $3.3 billion in free cash flow that year, funding content through a relentless debt issuance machine that pushed total long-term debt above $14 billion. Wall Street was deeply divided on whether the company could ever generate positive free cash flow without cutting content spend. Fast forward to 2025: Netflix produced $8+ billion in FCF while spending approximately $17 billion on content. The swing from negative $3.3 billion to positive $8 billion represents an $11+ billion improvement in annual cash generation over six years. We struggle to find a comparable financial transformation at this scale in consumer technology.

The mechanics of the improvement are instructive. Revenue doubled from $20 billion in 2019 to $39 billion in 2025, while content spend grew by only 30% ($13 billion to $17 billion). That widening spread between revenue growth and content cost growth is the engine of operating leverage. Netflix is amortizing its fixed content investment over a larger and growing subscriber base, each incremental subscriber adds revenue with near-zero marginal content cost. This is the same dynamic that made cable networks so profitable for decades — except Netflix operates globally and has no affiliate fee negotiations to navigate.

The Advertising Opportunity Nobody Is Modeling Correctly

When Netflix launched its ad-supported tier in November 2022, the skeptics were loud. “Netflix's brand is built on ad-free viewing.” “Consumers will reject ads.” “The CPMs will never justify the cannibalization of higher-priced tiers.” Every single one of those predictions was wrong.

The ad tier reached 40+ million monthly active users by Q4 2025 and now represents more than 50% of all new sign-ups in markets where it is available. Think about that for a moment. Half of every new Netflix subscriber is choosing to watch ads in exchange for a lower price point. This is not cannibalizing the premium tier — it is expanding the total addressable market by bringing in price-sensitive consumers (students, households in emerging markets, casual viewers) who would not subscribe at $15.49 or $22.99 per month.

The revenue math is where it gets interesting. Netflix commands CPMs of $45–60, roughly 2x the industry average for ad-supported streaming. Why? Because Netflix delivers what advertisers want most: massive reach (300M+ subscribers), premium content environments (no user-generated content risk), and demographic targeting across 190+ countries. An ad-tier subscriber watching 2 hours per day with 4–5 minutes of advertising per hour generates roughly $12–18 per month in ad revenue on top of the $6.99 subscription fee. That means an ad-tier subscriber can be more valuable per-user than a standard subscriber paying $15.49 with no ads. This is the math that will drive Netflix's revenue per membership higher over the next three years, even without price increases.

The Path to $9 Billion in Ad Revenue

Our model assumes ad-tier MAU reaches 70–80 million by 2028 (driven by continued password sharing conversions, emerging market growth, and the natural migration of price-sensitive consumers to the cheapest tier), with average annual ad revenue per user of $120–130. That produces $8.4–10.4 billion in advertising revenue, or roughly $9 billion at the midpoint. Consensus estimates for 2028 ad revenue sit closer to $5–7 billion, which we believe is conservative based on the MAU trajectory and Netflix's demonstrated ability to command premium pricing. For perspective on how advertising models transform media company valuations, our coverage of the Alphabet advertising machine provides useful context.

One thing the Street keeps underweighting: Netflix is building its own ad-tech stack. The initial Microsoft partnership handled programmatic buying, but Netflix has been investing heavily in first-party measurement, targeting, and self-serve buying tools. Owning the ad infrastructure means higher take rates (no middleman), better data utilization, and the ability to offer advertisers bespoke sponsorship packages around tentpole content releases. When a new season of Squid Game or Wednesday drops to 100 million households simultaneously, the advertising inventory around that event is extraordinarily valuable.

Live Sports: The Missing Piece Falls Into Place

Netflix's entry into live sports was not an impulse buy. It was the logical completion of an advertising strategy. Live sports are the last bastion of must-watch, non-skippable, appointment television. They are the only content category where advertisers will pay $50+ CPMs without blinking, because the audience is guaranteed to be watching in real time with no fast-forward button.

The NFL Christmas Day games in December 2024 were the proof of concept. An estimated 65 million viewers tuned in across two games — the most-watched live event in streaming history by a wide margin. Advertisers paid a reported $6.5 million per 30-second spot, comparable to Sunday Night Football pricing on NBC. Netflix demonstrated, in a single day, that its platform could handle live event-scale traffic (there were some buffering hiccups, which they have since addressed with CDN investments) and deliver the kind of audience that justifies top-tier ad pricing.

WWE Raw is arguably the more strategic acquisition. The 10-year deal (reportedly worth $5 billion total, or $500 million annually) brings 52 weeks of live programming to Netflix starting January 2025. That is weekly appointment viewing with a passionate, global fanbase — WWE operates in 180+ countries, aligning perfectly with Netflix's geographic footprint. Early ratings data shows WWE Raw on Netflix averaging 2.5–3 million U.S. viewers per episode, above the 1.8 million average on USA Network in 2024, with significant international viewership on top.

Password Sharing Crackdown: The $2 Billion Catalyst Nobody Predicted

When Netflix announced its paid sharing initiative in early 2023, the market panicked. Sell-side analysts modeled mass cancellations. Social media erupted with “I'm canceling Netflix” posts. The stock wobbled. What actually happened was the exact opposite of what the bears predicted.

Netflix added 30 million net subscribers in 2024, its strongest growth year since the pandemic-driven surge of 2020. Of the estimated 100+ million households that were freeloading through shared passwords, only 2–3% canceled outright. The rest either converted to paid subscriptions (35–40%) or migrated to the cheaper ad-supported tier (which still generates meaningful revenue through advertising). The crackdown accomplished something remarkable: it simultaneously grew the subscriber base, increased average revenue per membership (because many converters chose higher-priced plans), and expanded the ad-tier audience — all without materially increasing content costs.

The long-tail effects persist into 2026. International markets where paid sharing enforcement rolled out later (parts of Latin America, Africa, Southeast Asia) are still seeing elevated conversion rates. And importantly, the crackdown reset consumer expectations. Password sharing is no longer normalized. New Netflix subscribers in 2025 and beyond sign up understanding they are paying for household-level access, which means the addressable market is effectively larger than it was when sharing was tolerated.

Streaming Platform Economics: Netflix vs. the Field

This table reveals the uncomfortable truth about streaming economics. Netflix is the only platform generating profits from streaming as a standalone business. Disney's DTC segment barely broke even after years of losses. Amazon treats Prime Video as a loss leader for Prime memberships and e-commerce retention. Apple TV+ exists to sell iPhones and keep users in the ecosystem. When you strip away the cross-subsidies, Netflix stands alone as proof that streaming can work as a business — not just a customer acquisition channel.

Content Spend: Doing More With (Relatively) Less

The Efficiency Flywheel

Netflix's content strategy has matured considerably since the era of “spend whatever it takes.” Total content spend in 2025 was approximately $17 billion, up only modestly from $16.3 billion in 2024 and well below what many analysts projected just two years ago. Yet output — measured in hours of original programming and licensed content — has increased. The company is getting more content per dollar, a function of several factors.

First, international production costs are structurally lower. A Korean drama that becomes a global hit (Squid Game cost roughly $21 million for season one) delivers vastly better ROI than a comparable U.S.-produced show at $150–200 million. Netflix now produces original content in 50+ countries, and roughly 60% of viewing hours on the platform come from non-English titles. This is not charity — it is ruthless capital allocation. Second, Netflix's recommendation algorithm ensures that content finds its audience efficiently. A niche documentary that would fail in a theatrical release can thrive on Netflix because the algorithm surfaces it to the 3–5 million subscribers most likely to watch it. Third, Netflix has gotten better at canceling underperforming shows quickly. The stigma of early cancellation has faded, and the company now evaluates content ROI with far more discipline than the “greenlight everything” era of 2018–2020.

Gaming: The Quiet Optionality

We are not going to pretend Netflix Games is a material revenue driver today. It is not. But the strategic optionality deserves mention. Netflix has acquired six game studios and offers 100+ mobile games to all subscribers at no additional cost. The primary purpose right now is engagement and churn reduction — a subscriber who plays games on Netflix is 15–20% less likely to cancel in a given month, according to internal data shared at the company's 2025 investor day. The secondary purpose is content extension: games based on Squid Game, Wednesday, and other IP franchises deepen franchise engagement. Could Netflix eventually monetize games through in-app purchases, ads within games, or a dedicated gaming subscription tier? Possibly. But we assign zero value to gaming in our base case and treat it as a free option.

International Growth: The Runway Is Longer Than You Think

Netflix operates in 190+ countries, but penetration rates vary enormously. In the U.S. and Canada (UCAN), Netflix has approximately 85 million subscribers out of roughly 130 million TV households — a penetration rate of ~65%. That is mature. Growth here comes from pricing power and ad-tier expansion, not subscriber additions.

But UCAN is only 28% of total subscribers. The other 72% comes from EMEA (95 million), LATAM (50 million), and APAC (52 million), where penetration rates are dramatically lower. India alone has 1.4 billion people and fewer than 15 million Netflix subscribers. Southeast Asia, the Middle East, Sub-Saharan Africa — these are regions with rapidly growing middle classes, improving broadband infrastructure, and smartphone penetration rates climbing past 70%. Netflix's ad-supported tier at local price points (as low as $2–3/month equivalent in some markets) makes the service accessible to hundreds of millions of potential subscribers who cannot afford $15/month.

We model international subscriber growth of 8–12% annually through 2028, driven primarily by APAC and EMEA. ARPU in these regions is significantly lower than UCAN ($6–9/month versus $17/month), but the advertising opportunity helps close the gap. An ad-tier subscriber in Brazil generating $4/month in subscription revenue and $8/month in ad revenue suddenly looks quite attractive on a per-user economics basis.

Operating Margins: 25% Was the Floor, Not the Ceiling

Netflix's 2025 operating margin of 28.1% exceeded the company's own long-term target of 25% that it set in 2022. Management has since guided for continued margin expansion, targeting “low-to-mid 30s” operating margins by 2027–2028. We think that is conservative. If advertising revenue scales to our $9 billion bull case by 2028, and content spend grows at only 3–5% annually (below revenue growth), Netflix could approach 35%+ operating margins.

The margin expansion story has three legs. First, content operating leverage (revenue growing faster than content costs). Second, G&A operating leverage (technology and corporate overhead are largely fixed costs that scale minimally with subscriber growth). Third, and most importantly, the advertising revenue mix shift. Every dollar of ad revenue carries an incremental margin of 60–70% because there are no content costs attributable to it — the content exists whether the subscriber sees ads or not. As ads grow from roughly 5% of total revenue today to 20–25% by 2028, the blended margin profile of the business improves structurally.

The Bear Case: What Could Go Wrong

Content Fatigue Is Real

Netflix produces more content than any single human can consume. That is both a strength and a risk. If hit rates decline — fewer Squid Games, fewer Wednesdays, more expensive flops — subscriber engagement metrics deteriorate and churn accelerates. The entertainment business has always been a hits-driven game, and Netflix is not immune to cold streaks. The company's advantage is data (they know what 300 million subscribers watch, when they pause, and when they drop off), but data does not guarantee hits. Creative risk is inherent to the business.

Valuation Premium Leaves Little Room for Misses

At 35–38x NTM P/E, Netflix trades at a meaningful premium to the S&P 500 (22x) and media sector peers (Disney at 18x, Comcast at 10x). The premium is justified only if Netflix executes flawlessly on ad-tier monetization, continues to grow subscribers internationally, and maintains its current content hit rate. Any stumble — a bad quarter of subscriber adds, ad revenue below expectations, a content slate that misfires — could trigger a 20–30% multiple compression. We saw this in April 2022 when the stock fell from $600 to $170 in six months on two consecutive subscriber misses. The company is in far better shape today, but the valuation leaves less margin for error than we would like.

Competition Never Truly Disappears

Disney, Amazon, and Apple have collectively spent over $100 billion on streaming content since 2019. While all three have pulled back spending, they have not exited the market. Amazon's Thursday Night Football and NBA rights give Prime Video must-watch live sports content. Disney's ESPN integration into Disney+ (planned for 2025–2026) could create the definitive sports streaming bundle. Apple continues to win Emmys and build prestige content. And YouTube — often overlooked in the “streaming wars” narrative — commands more watch time than any single streaming platform and is aggressively growing its living room presence through YouTube TV and NFL Sunday Ticket. For a comprehensive view of how tech giants are allocating capital across entertainment, gaming, and media, our analysis of Apple's broader strategy offers relevant perspective.

Valuation: Paying Up for Quality

The scenario table above uses a 25x forward P/E multiple on 2028 earnings, which is conservative for a business growing revenue at 12–15% with expanding margins and improving capital returns. Our base case implies roughly 25–30% upside from current levels over a three-year holding period, equating to an 8–10% annualized return before dividends or buybacks. Not spectacular, but solid for a large-cap compounder with this quality of business. The bull case — which requires ad revenue scaling to $9B+ and operating margins reaching 35% — offers meaningfully more upside but depends on execution against ambitious targets.

One thing worth noting: Netflix initiated its first-ever share buyback program in 2024 and repurchased approximately $6 billion in stock during the year. With free cash flow trending toward $10–12 billion by 2027, buybacks will become an increasingly meaningful driver of per-share earnings growth. A 3–4% annual share count reduction adds roughly 300–400 basis points to EPS growth on top of operating income growth. This is the compounding machine that the best large-cap growth investors live for.
