Roku seen hitting 25% platform revenue growth as political ads and World Cup bolster outlook

Roku Inc (NASDAQ:ROKU) has a credible path to outperforming its own full-year guidance, driven by political advertising, World Cup viewership, and ongoing improvements to ad fill rates, according to Jefferies.

In a mid-year review of its thesis, the investment bank outlined an upside case of roughly 25% year-over-year growth in platform revenue for fiscal 2026, compared to Roku’s current guidance implying approximately 21% growth.

That revenue outperformance could flow through to EBITDA of around $775 million, well above the Street consensus of $679 million, analysts believe.

Jefferies flagged the Q2 platform revenue guide as looking conservative, noting an implied 5 to 6 percentage point deceleration in subscription revenue growth despite an easier comparable period and new premium subscription offerings from Peacock and Apple TV+ coming online.

For the second half, political advertising and World Cup-related spend represent incremental drivers the firm does not believe are fully reflected in Roku’s current full-year guidance.

On margins, platform gross margins at the high end of the 51 to 52% guided range, combined with mid-single-digit operating expense growth, support the $775 million EBITDA upside case. Device margins appear largely de-risked for fiscal 2026, with second-half memory pricing mostly contracted.

Beyond 2026, Roku’s new home screen represents a key monetization lever, according to Jefferies, with biddable ad tiles potentially adding 4 to 7% in platform revenues over time. A small and medium-sized business ads manager and owned-and-operated content offerings, including its Howdy product, were also cited as emerging growth vectors, while international expansion and lower-funnel performance advertising on connected TV offer additional optionality.

Jefferies said its longer-term bull case rests on a multi-year runway to improve fill rates, expand ad inventory, and drive higher subscription conversion, rather than one-time events such as elections or sporting tournaments.

Despite its upside scenario, the firm is maintaining its base-case fiscal 2026 estimates at approximately 21% platform revenue growth and $676 million EBITDA. Analysts have a Buy rating and $150 price target on the streaming platform.
