NFLX vs. ROKU: Which Ad-Supported Streaming Stock is the Better Buy?
Read MoreHide Full Article
Key Takeaways
Roku stands out as the better buy, driven by faster platform growth and a lower 2.26x forward P/S valuation.
Roku posted $1.2B Q4 platform revenues, guides 18% growth and targets $1B free cash flow by 2028.
Netflix hit 325M members, sees ads near $3B in 2026, but revenue growth slows to 12-14% amid rising costs.
The ad-supported streaming revolution has put two compelling investment stories in focus: Roku (ROKU - Free Report) and Netflix (NFLX - Free Report) . Roku is a neutral streaming operating system monetizing through advertising and content partnerships, while Netflix — the world's dominant subscription streamer — is aggressively scaling its ad tier. Both are capitalizing on the secular migration of linear TV ad budgets to connected TV.
Their business models, growth trajectories and valuations differ meaningfully. Let's delve deep and closely compare the fundamentals of the two stocks to determine which one is a better investment now.
The Case for ROKU Stock
Roku's investment thesis is anchored in structural advantage: it is the operating system layer of streaming. With nearly half of all U.S. TV streaming occurring on Roku-powered devices, the company controls the home screen, the discovery experience, and increasingly the content itself through The Roku Channel. In fourth-quarter 2025, Roku achieved its largest-ever quarter for premium subscription net additions, with platform revenue exceeding $1.2 billion — up 18% for the full year — while net income reached a record $80 million.
Management's forward guidance signals sustained momentum. Roku projects first-quarter 2026 platform revenue growth of over 21% and full-year growth of 18%, with adjusted EBITDA guidance raised to $635 million — representing more than 50% year-over-year growth — and 267 basis points of margin expansion. The company expects operating income to be positive for full-year 2026 and targets $1 billion in free cash flow by the end of 2028. CEO Anthony Wood confirmed Roku is on track to surpass 100 million streaming households in 2026.
On the content and advertising front, Roku added 15 new free channels to The Roku Channel in March 2026, strengthening its FAST ecosystem. In February 2026, Roku announced exclusive streaming bundles and the expansion of its Howdy subscription service. Its AI-driven personalization strategy and partnerships with Amazon and The Trade Desk are transforming the platform into a precision advertising engine. The Roku Channel captured a record 3% share of total U.S. television viewership in December 2025, underscoring growing platform engagement and FAST leadership.
The Zacks Consensus Estimate for 2026 earnings is pinned at $2.10 per share, indicating a staggering 255.93% increase from the previous year.
Netflix commands undeniable scale in global streaming, having crossed 325 million paid memberships in fourth-quarter 2025. Full-year 2025 revenues reached $45.2 billion, up 16% year over year, and operating margin expanded to 29.5%, reflecting its evolution into a highly profitable media powerhouse. However, as the subscriber base matures, meaningful membership growth is becoming increasingly difficult to sustain, and the company's ability to drive top-line expansion is shifting more heavily toward pricing and advertising rather than net new additions.
For 2026, Netflix projects revenues of $50.7 billion to $51.7 billion, representing 12-14% growth, and expects ad revenues to roughly double to approximately $3 billion. Its March 2026 price hike — raising its ad-supported plan to $8.99, Standard to $19.99 and Premium to $26.99 — signals pricing confidence and is likely to funnel more subscribers toward the ad-eligible tier. That said, the company walked away from its proposed $83 billion acquisition of Warner Bros. Discovery in late February 2026, declining to match a superior rival bid, and is instead channeling capital into a $20 billion content budget — a 10% increase that will pressure near-term margins.
Netflix's 2026 content pipeline is formidable, anchored by Peaky Blinders: The Immortal Man, One Piece Season 2, The Night Agent Season 3 and live sports programming, including MLB and WWE. In March 2026, Netflix also announced expanded ad-tech capabilities, including Amazon DSP and Yahoo DSP integrations, a Conversion API and AI-driven interactive mid-roll ads, strengthening its advertising proposition. Nevertheless, the 2026 operating margin guidance of 31.5% reflects rising content amortization and acquisition-related costs, with revenue growth slowing from 16% in 2025 toward a guided 12-14% in 2026.
The Zacks Consensus Estimate for NFLX’s 2026 earnings is pegged at $3.14 per share, indicating a 24.11% increase from the previous year.
Both Roku and Netflix trade at premium valuations, but the extent of that premium differs significantly. Roku trades at a forward P/S of 2.26x, while Netflix commands a steeper 7.49x multiple. While Netflix's premium reflects its established profitability and global scale, Roku's relatively modest multiple is better justified on a growth-adjusted basis, given its faster platform revenue acceleration and expanding profitability runway.

Conclusion
Roku holds a compelling edge over Netflix for growth-oriented investors. Its superior platform revenue growth trajectory, AI-enhanced advertising capabilities, expanding FAST ecosystem, path to $1 billion in free cash flow by 2028, growing streaming household base, and a far more attractive 2.26x forward P/S multiple make a strong fundamental case. Netflix, while financially formidable with established profitability and a powerful content engine, faces decelerating revenue growth, rising content cost pressures, and a demanding 7.49x valuation that limits near-term upside. Investors should buy Roku stock for its greater upside potential and hold or wait for a better entry point in Netflix. ROKU currently sports a Zacks Rank #1 (Strong Buy), whereas NFLX has a Zacks Rank #3 (Hold). You can see the complete list of today’s Zacks #1 Rank stocks here.
