As Netflix reports its Q4 2024 earnings today, January 21, 2025, the company’s ad-supported business continues to evolve as a central pillar of its growth strategy. With projections to double its ad revenue in 2025, Netflix is poised to expand its footprint in the competitive streaming ad market. However, ambiguity surrounding baseline revenue figures has left us all piecing together estimates to gauge the true scale of its advertising success.
Projections vs. Clarity
Netflix has not disclosed specific figures for its ad revenue, but Statista estimates it generated $2.12 billion from advertising in 2024. If Netflix’s statement about doubling revenue in 2025 is taken literally, this would imply $4.24 billion in ad revenue this year. Yet, New Street Research projects a more modest $3.2 billion for 2025, raising questions about the assumptions underpinning these forecasts.
This gap between projections may reflect differing levels of optimism. New Street’s estimate could account for potential declines in CPMsor more conservative adoption rates for Netflix’s ad-supported plans. Conversely, Netflix’s statement about doubling ad revenue may represent a broad ambition rather than precise guidance. Regardless, the growth trajectory of Netflix’s ad business signals strong potential, even if the exact scale remains uncertain.
Growth in Ad-Supported Plans
Netflix’s ad-supported plans are gaining significant traction, with memberships growing 35% quarter-over-quarter as of Q3 2024 and accounting for 50% of new sign-ups in regions where the tier is available. These figures demonstrate that the lower-priced ad-supported plans are resonating with consumers, but without clarity on the baseline for this 35% growth, it is difficult to contextualize the absolute scale of these gains.
Encouragingly, engagement metrics for ad-supported plans remain robust, with subscribers averaging two hours of daily viewing—on par with non-ad plans. These numbers suggest that Netflix is effectively delivering value to both advertisers and consumers, even as it builds out its advertising infrastructure.
Challenges in Monetization
Netflix’s leadership has acknowledged the challenges inherent in scaling its ad business. CEO Greg Peters noted that while inventory is growing quickly, the company’s ability to monetize it has lagged. This has created a temporary drag on ARM (average revenue per membership) but sets the foundation for longer-term growth. The rollout of Netflix’s in-house ad platform, which began testing in Canada in late 2024 and is set to launch globally by the end of 2025, is central to addressing these challenges and unlocking additional revenue opportunities.
Competitive Context: YouTube’s Benchmark
For perspective, YouTube generated $8.92 billion in ad revenue in Q3 2024 alone—a figure that underscores the immense scale of mature ad-supported platforms. While Netflix’s projected 2025 revenue, even at $4.24 billion, remains far smaller, its rapid adoption rates and strong engagement suggest a growing foothold in the CTV ad market.
Strategic Moves: Expanding the Ad Ecosystem
Netflix’s decision to phase out its $11.99 Basic plan in favor of the $6.99 ad-supported tier reflects its commitment to driving consumer adoption of ad plans. This move aligns with its long-term strategy to lower barriers to entry and scale its ad inventory while maintaining a high-quality user experience.
Looking Ahead
The divergence between New Street Research’s $3.2 billion projection and a doubling of Statista’s $2.12 billion estimate highlights the complexity of predicting Netflix’s ad revenue trajectory. Regardless of where the final numbers land, Netflix’s ad business is positioned for significant growth as it refines its offerings, monetizes its expanding inventory, and continues to capture consumer interest. With plans to broaden its ad tech capabilities and enhance advertiser value, Netflix is steadily carving out its space in the evolving streaming advertising market.
