Roku vs. Comcast: Which Streaming Stock is the Better Investment?

Roku ROKU and Comcast CMCSA are both active players in the fast-growing streaming market, each with a unique approach. Roku has built its platform around ad-supported streaming and user-friendly content discovery, while Comcast is expanding Peacock through a mix of premium content, live sports and strategic bundling across its broader media and broadband ecosystem.As consumers spend more time streaming and advertisers shift dollars toward digital platforms, the key question is: Which company is better positioned to benefit in 2025? Let’s compare their performance and strategies to find out.The Case for ROKU StockRoku’s streaming platform showed strong growth in the first quarter of 2025, strengthening its position as a top player in the streaming space. Platform revenues rose 17% year over year to $881 million, supported by growth in both video advertising and streaming service distribution. Roku now reaches over half of all U.S. broadband households, with more than 125 million people using its Home Screen every day to start their TV experience.A big part of this success was The Roku Channel, which became the #2 app on the platform in the United States based on engagement. Streaming hours on the channel jumped 84% from last year, aided by personalized recommendations shown directly on the home screen. Over 85% of viewing came through these features rather than the app, showing how well Roku guides users to content.Roku also continues to grow its streaming ecosystem by adding more content and making it easier for users to discover what to watch. Its library includes Roku Originals, live channels and easy access to popular subscription services, all in one place.With more people watching content through streaming, Roku is in a strong position. Its growing user base, smart content discovery tools and focus on improving the streaming experience make it one of the most reliable platforms in today’s digital viewing market.The Case for CMCSA StockComcast’s streaming business, led by Peacock, continued to grow in the first quarter of 2025. Peacock delivered double-digit revenue growth and narrowed its year-over-year losses by more than $400 million. This improvement was supported by better monetization of paid subscribers, a price increase from 2024 and the addition of Charter subscribers, which helped the platform reach 41 million paid users by quarter-end.Peacock’s content strategy centers around a wide mix of programming, including NBCUniversal originals, next-day NBC and Bravo shows, Pay-One movies like Wicked and a strong lineup of live sports. This mix is designed to appeal to a broad audience and drive consistent streaming engagement across different user groups.While digital advertising on Peacock remained relatively stable, the platform is still not profitable. Total advertising revenues for NBCUniversal declined during the quarter due to the timing of sports events and comparisons to a strong political ad year. Even with bundling efforts and expanded ad formats, Peacock’s financial performance remains under pressure.Despite making clear progress, Peacock still requires heavy investment to stay competitive. Its growing sports portfolio, including new rights like the NBA, adds more cost in the short term. As a result, while subscriber numbers are rising, Peacock continues to operate at a loss, and its long-term path to profitability is still taking shape.Price Performance and Stock Valuation of ROKU and CMCSAIn the trailing six months, Roku shares have lost 12.4% compared with Comcast’s decline of 20.2%.

Although ROKU is trading at a premium compared to CMCSA, the premium valuation reflects investor confidence in the company's growth potential for the rest of 2025.

The company is growing steadily, with rising platform revenues, increased engagement on The Roku Channel and strong advertiser demand.

These results have led to improved earnings expectations and steady investor confidence.Comcast’s Peacock, on the other hand, is still in the building phase. While subscriber numbers are growing and losses have narrowed, the platform is not yet profitable and continues to require heavy investment. Compared to Roku’s focused, ad-driven model, Peacock’s growth path is slower and more uncertain.ROKU currently carries a Zacks Rank #2 (Buy), whereas CMCSA has a Zacks Rank #3 (Hold).
