Snapshot

Streaming video and Connected TV (CTV) is a $45B+ annual revenue business across the four tracked companies (Netflix, Disney, Comcast/Peacock, Roku), built on two revenue streams: monthly subscription fees paid by viewers, and advertising sold against the video they watch. Netflix alone has 325 million paid subscribers globally. CTV ad spend in the US reached $28.6B in 2024 and is growing at roughly 14-16% per year est., roughly double the overall ad market growth rate. The structural shift underneath: linear (cable/satellite) TV now captures only 20% of US TV viewing time per Nielsen, while streaming holds 47.5% as of December 2025. Pay TV penetration has fallen from 88% of US households in 2010 to below 50% in 2026, with only 36% of US adults still subscribing to cable or satellite.

The product being bought and sold: attention time on a screen. Subscribers pay $7-$23/month for content; advertisers pay for impressions against that attention. The secular shift from linear TV to streaming is roughly half-complete by viewing share (47.5%) and accelerating by cord-cutting rate (~5-6M pay TV subscribers leaving per year). Streaming has captured the viewing share but not yet the proportional ad dollars — CTV holds roughly one-third of TV ad spend despite nearly half the viewing time.

The product & how money is made

Two products, sold to two different buyers:

1. Subscription access (sold to viewers)

Viewers pay a monthly fee for on-demand access to a library of video content — movies, series, live sports, and originals. "SVOD" means subscription video on demand. Pricing ranges from roughly $8/month (ad-supported tiers) to $23/month (premium ad-free). Netflix's global average revenue per member (ARPU) was $11.70/month in 2024, with US/Canada at $17.26 and Asia Pacific at $7.34. The main cost is content: Netflix spent approximately $18B on content in 2025 and guided to roughly $20B for 2026.

2. Advertising impressions (sold to brands)

CTV advertising means commercials delivered through internet-connected television — either within streaming apps (Netflix, Hulu, Peacock, Disney+) or on the CTV platform itself (Roku's home screen, screensaver, and FAST channels). Unlike linear TV where ads are sold by daypart and estimated ratings, CTV ads are sold programmatically with household-level targeting. Roku disclosed ad revenue separately for the first time in Q1 2026: $612.7M in the quarter (+27% YoY). Netflix's ad revenue was approximately $1.5B in 2025, with a target of roughly $3B in 2026.

How it converts to cash

• Netflix: $45.2B revenue (FY2025), 29% net margin, $9.5B free cash flow. Content amortization is the dominant cost line. Capex is light (~$688M).
• Disney (DTC segment): $5.49B streaming revenue in Q2 fiscal 2026 (+13% YoY), $582M operating income (10.6% margin, up 88% YoY). Turned profitable in 2024 after years of losses. The DTC segment includes Disney+, Hulu, and ESPN+.
• Roku: $1.25B total revenue Q1 2026 (+22% YoY), of which platform revenue (ads + subscription distribution) is $1.13B (91%). Net-income positive in 2025 ($88M on $4.7B revenue). FCF was $478M in FY2025.
• Peacock (Comcast): $2.1B revenue Q1 2026 (+12% YoY), operating loss of $432M. The loss widened due to NBA rights and Winter Olympics costs. Comcast expects Peacock to reach profitability in Q2 2026.

Demand

Contracted / observable demand

• Netflix: 325 million paid subscribers as of end-2025. Netflix stopped disclosing quarterly subscriber counts starting Q1 2025 but continues to report revenue (Q1 2026: $12.25B, +16% YoY). contracted
• Disney+: 132 million subscribers as of Q4 2025 (last disclosed quarter before Disney stopped reporting the metric). contracted
• Peacock: 46 million paid subscribers as of Q1 2026, up from 41M a year earlier (+12%). contracted
• Roku: 100 million streaming households reached in April 2026 (up from 90M+ in late 2025). 38.7 billion streaming hours in Q1 2026 (+8% YoY). contracted
• Ad demand: Roku's video ad impressions grew 59% YoY in Q1 2026. Netflix's ad-tier monthly active viewers reached 250 million by May 2026, up from 94 million in May 2025 — a 166% increase in 12 months. 45% of Netflix US households now watch on the ad-supported tier. contracted

Forecasted demand

• US CTV ad spend: projected to grow from $28.6B (2024 actual) to ~$38B (2026) to ~$47B (2028), at which point it is forecast to surpass linear TV ad spend for the first time. est.
• Subscriber growth: mature in US/Canada (Netflix US/Canada is ~90M of 325M total). Growth comes from international markets (EMEA 101M, APAC 58M, LATAM 53M for Netflix) and from converting ad-free subscribers to ad-supported tiers, which increases per-member monetization. est.
• Cord-cutting tailwind: US pay TV loses roughly 5-6M subscribers per year est.. 80+ million US households are projected to rely solely on non-pay-TV services by end of 2026 est.. The ad dollars that follow those viewers migrate to CTV.
• Sports rights as demand anchor: live sports are the strongest driver of new streaming subscriptions. Peacock's Q1 was fueled by Super Bowl and Olympics. ESPN's standalone DTC launch (late 2026/2027) would shift more sports demand to streaming.

Supply

What is being supplied

The "supply" in streaming is two-fold: (1) the content libraries that attract and retain subscribers, and (2) the ad inventory (available impressions) that can be sold to brands. More content drives more viewing hours, which generates more ad impressions.

Content supply — capacity and cost

• Netflix: ~$18B content spend in 2025, guided to ~$20B in 2026 (+10%). The largest single content budget in the industry. Netflix produces originals in 50+ countries and holds global rights.
• Disney: content spending across Disney+, Hulu, and ESPN+ is embedded in its Entertainment segment costs. Disney owns Marvel, Star Wars, Pixar, National Geographic, and the ABC/FX/Hulu library. Shifting strategy from growth-at-all-costs to profitable scale — content spend is being disciplined.
• Peacock: $1.95B in programming and production costs in Q1 2026 alone, driven by NBA, Olympics, and Super Bowl rights. NBC's broadcast content (including live sports) feeds into Peacock at incremental cost.
• Roku: does not produce significant original content. Roku supplies the operating system layer and FAST channels (free ad-supported streaming TV). Roku TV OS is built into third-party smart TVs. Content is supplied by the streaming apps running on Roku's platform.

Ad inventory supply

• Netflix's ad inventory is expanding rapidly — 250M monthly ad-tier viewers generating significant unsold inventory. Netflix is building an in-house ad tech platform (replacing Microsoft as its ad-serving partner) to improve fill rates and targeting.
• Roku sold 59% more video ad impressions in Q1 2026 than Q1 2025, reflecting both more streaming households and more ad load per hour.
• CTV ad inventory overall is growing faster than advertiser demand can fill it, which is why CTV CPMs (cost per thousand impressions) remain below linear TV CPMs despite better targeting. est.

The bottleneck

Content cost is the structural bottleneck. Live sports rights — NFL, NBA, Olympics, FIFA — are the scarcest and most expensive content. The NBA's new 11-year media deal (starting 2025-26 season) costs ~$76B across Disney/ESPN, Amazon, and NBCUniversal, roughly triple the prior deal. These costs are locked in and non-cancellable. Outside of sports, scripted content costs are falling as AI tools reduce post-production, dubbing, and VFX costs, and as streamers become more disciplined about greenlighting. est.

The gap

The gap in this sector is not physical capacity (like power in data centers) — it is a monetization gap. Streaming holds 47.5% of viewing share but captures roughly one-third of TV ad dollars est.. The reasons: programmatic CTV ad buying infrastructure is still maturing, measurement standards are fragmented across platforms, and many advertisers still run linear TV buys out of inertia. That gap is narrowing at 14-16% per year est. as ad budgets follow eyeballs. On the subscription side, US/Canada is near saturation (~90M Netflix households in a ~130M household market est.), so incremental revenue comes from price increases, ad-tier monetization, and international expansion.

Subscription prices have risen across major markets over the past two years. CTV ad CPMs are below linear TV CPMs despite better targeting capabilities. Netflix's ad revenue per member is a fraction of its subscription ARPU ($6/year ad revenue per ad-tier viewer vs $140-207/year subscription ARPU by region).

The players

Netflix and Roku are streaming pure-plays. Disney and Comcast are conglomerates where streaming is one segment alongside theme parks, cable networks, broadband, and film studios. For DIS and CMCSA, the streaming segment cannot be cleanly separated from the parent company's balance sheet and cash flows. Roku occupies a different niche — it does not produce content or charge subscribers directly; it sells the operating system and ad platform that sits between viewers and all the other streaming apps.

The price of exposure

Netflix (NFLX) — $81.52 per share

• Market cap: $343B on 4.21B shares (post-10:1 stock split). Enterprise value: ~$348B.
• EV / TTM revenue: 7.4x. EV / TTM EBITDA: 24.3x. P/E (trailing): 26.3x. Forward P/E: 21.2x.
• FCF yield: $9.5B FCF / $343B market cap = 2.8%.
• Implied math: at 25x earnings, the market is pricing ~$13.7B of annual earnings — roughly what Netflix earned in the TTM. At 20x forward earnings, the implied earnings target is ~$17B.

Disney (DIS) — $99.39 per share

• Market cap: $173B on 1.74B shares. Enterprise value: ~$221B.
• EV / TTM revenue: 2.3x. P/E (trailing): 15.9x. Forward P/E: 13.3x.
• Streaming segment: DTC revenue ~$22B annualized, at 10.6% operating margin = ~$2.3B streaming operating income annualized. The whole company earned $11.2B net income TTM. Streaming is ~20% of operating profit.
• Debt load: $44.9B total debt, $5.7B cash = ~$39B net debt. That is 2.0x TTM EBITDA ($19.7B).
• Buybacks: targeting $8B+ in FY2026.

Comcast (CMCSA) — $23.52 per share

• Market cap: $84B on 3.56B shares. Enterprise value: ~$169B.
• EV / TTM revenue: 1.4x. EV / TTM EBITDA: 4.8x. P/E (trailing): 4.6x.
• Peacock is a small, money-losing part: Peacock revenue ~$8.4B annualized, still losing ~$432M/quarter. The rest of Comcast (broadband, cable, NBCUniversal, theme parks) generates the vast majority of the $33.6B operating cash flow. Buying CMCSA is a broadband/media conglomerate where Peacock is an emerging segment.
• Debt load: $98.9B total debt, $9.5B cash = ~$89B net debt. That is 2.5x TTM EBITDA.

Roku (ROKU) — $122.20 per share

• Market cap: $18B on 131M shares. Enterprise value: ~$16B (net cash position).
• EV / TTM revenue: 3.3x. EV / TTM EBITDA: 41.9x. P/E (trailing): 91x.
• Implied math: at $18B market cap and $478M TTM FCF, FCF yield is 2.7%. For the $18B market cap to look like a 20x-earnings business, Roku needs ~$900M of net income — about 4.5x its TTM net income. That requires roughly doubling margins from 4% to 18% at current revenue, or growing into it at 22%/yr revenue growth with margin expansion.
• Balance sheet: $2.4B cash vs $523M debt = $1.9B net cash.

What to deep-dive next

• Netflix ad monetization ramp: 250M ad-tier viewers generating only ~$6/year in ad revenue per viewer vs linear TV's $30-50/viewer equivalent est.. What is the realistic steady-state ad ARPU once the in-house ad tech platform is operational?
• Sports rights economics: the NBA deal ($76B/11yr across ESPN, Amazon, NBCU) and NFL renewals are the largest content commitments. What is the actual ROI per subscriber for each sports package? Does live sports generate positive unit economics at current rights costs?
• Disney streaming margin trajectory: DTC margins went from deeply negative to 10.6% in two years. Netflix operates at ~30%. How much of the gap is structural (Disney's higher content cost per subscriber) vs temporary (scale)?
• Roku platform defensibility: Roku is the OS layer for 100M households. What is the lifetime value of a Roku household? How defensible is the OS position as smart TV manufacturers (Samsung Tizen, LG webOS, Google TV, Amazon Fire TV) compete?
• Peacock path to profitability: Comcast says Q2 2026 is the inflection. What does steady-state profitability look like for a fourth-place streaming service with 46M subs and heavy sports rights costs?
• Churn and bundling economics: Netflix 2.1% monthly churn vs Disney+ 5.5% est.. How much do bundles (Disney+Hulu, Peacock+cable) reduce churn? What does the bundling math look like for customer acquisition cost?
• International ARPU expansion: Netflix ARPU ranges from $17.26 (US/Canada) to $7.34 (APAC). As APAC and LATAM subscriber bases grow, does blended ARPU rise (pricing power) or fall (geographic mix shift)?
