However, the dominance of incumbent platforms is being challenged by a wave of corporate consolidation. As major media conglomerates seek to achieve economies of scale and combat the fragmentation that has plagued the streaming industry since its inception, the landscape is shifting from a multitude of disparate apps toward a "mega-bundle" model reminiscent of traditional cable television. This evolution presents both significant opportunities for streamlined audience targeting and lingering challenges regarding measurement transparency and cost efficiency.
A Year of Strategic Consolidation
The streaming industry is currently defined by a "bigger is better" philosophy. For years, the rapid proliferation of niche streaming services created a fragmented environment that made it difficult for advertisers to achieve reach without overspending on redundant platforms.
The timeline for 2026 is marked by high-stakes mergers intended to rectify this fragmentation:
- Late 2026: The Walt Disney Company is scheduled to complete the full integration of Hulu into the Disney+ interface, effectively creating a single, comprehensive streaming destination for its subscribers.
- Mid-2026: Pending regulatory approval regarding the Paramount-Skydance acquisition of Warner Bros. Discovery, the industry expects the merger of Paramount+ and Max into a singular, powerhouse streaming service.
These maneuvers are largely viewed as defensive and offensive tactics to compete with the likes of YouTube and Amazon Prime Video. By consolidating inventories, these legacy media companies hope to simplify the buying process for marketers, who have long complained about the administrative burden of managing campaigns across dozens of fragmented platforms.
The Budgetary Landscape and Market Dominance
Data from the Glossy survey underscores the entrenched position of tech-first platforms. In 2025, YouTube maintained its lead, with 75% of respondents placing ads on the platform. Amazon’s Prime Video (with ads) captured 47% of respondents, while Hulu and Paramount+ followed closely at 43% each.
When analyzing budgetary priority, the correlation remains strong. Half of all surveyed marketers (50%) identified YouTube as the recipient of the largest portion of their 2025 ad spend. Prime Video (18%) and Hulu (8%) rounded out the top three. This concentration of capital suggests that while advertisers are experimenting with a wide array of platforms, they are increasingly funneling their primary resources into environments that offer proven reach and robust technological infrastructure.
The Measurement Paradox: Walled Gardens vs. Data Collaboration
Despite the increased spending, measurement remains the most significant friction point for brand managers. As streaming services have scaled, many have adopted "walled garden" strategies, utilizing proprietary encryption and restricting the flow of granular audience data to protect their competitive advantage. This opacity makes it notoriously difficult for marketers to track the customer journey from ad exposure to final purchase.
Industry leaders are now looking toward data collaboration to bridge these gaps. Kristina Shepard, executive vice president of streaming performance sales and partnerships at NBCUniversal, notes that the industry is trending toward "smaller, higher-quality, more actionable datasets." Partnerships with retail media networks—such as the integration of streaming benefits into Walmart+ memberships—are enabling more effective closed-loop attribution. By linking media exposure directly to transaction data, advertisers can finally move beyond vanity metrics like impressions and clicks to measure tangible business lift.
Harry Browne, vice president of TV, audio and display innovation at the performance marketing agency Tinuiti, highlights that the last 12 months have seen a meaningful improvement in measurement capabilities. "We have seen a lot of focus on ways to bring deterministic results to environments that didn’t used to have them," Browne noted. By leveraging clean room solutions and conversion API (CAPI) tools, agencies are now able to track user behavior with greater accuracy, effectively pulling back the curtain on previously "black box" environments.
The Economic Outlook: CPM Stabilization
The rapid rise of ad-supported streaming tiers created a temporary surplus of ad inventory, which exerted downward pressure on Cost Per Mille (CPM) rates. While this was a boon for advertisers in the short term, it created a volatile marketplace.
As the industry consolidates, experts anticipate a shift in pricing dynamics. Browne suggests that the upcoming mergers will likely act as a stabilizing force for CPMs. As the number of major ad-supported platforms contracts, the "fire sale" pricing often seen in fragmented markets is expected to bottom out.
YouTube’s managing director of U.S. video deals and creative works, Brian Albert, argues that the conversation is already shifting. "Looking ahead, the efficiency of the spend will become more important than the raw cost of the impression," Albert said. He posits that marketers are moving away from chasing the lowest possible rate and are instead prioritizing quality and business outcomes—a trend that favors platforms with the most advanced targeting capabilities.
Brand Safety and the Transparency Dilemma
While the industry moves toward consolidation, unique challenges persist for specific platforms. Brand safety remains a critical consideration for YouTube, with 17% of survey respondents citing it as their primary concern. Because of the vast volume of user-generated content, advertisers often fear their brand appearing alongside controversial or unsuitable material.
Conversely, for platforms like Disney+, Hulu, and The Roku Channel, the primary concern is not safety, but transparency. Advertisers are increasingly demanding clearer visibility into the specific content environments where their ads appear.
This demand for transparency is rooted in a shift toward "brand acceleration." Lauren Sherman-Kaoud, chief marketing and creative officer at the home goods brand Ruggable, emphasizes that CTV functions as a trust-building mechanism. "When you’re watching a show, and a brand pops up, it is still meaningful to the consumer that the brand is showing up in that larger format," she explained. Advertisers are no longer just looking for eyeballs; they are looking for the prestige and contextual alignment that premium streaming content provides.
Implications for the Future
The streaming landscape is reaching a point of maturity where the novelty of ad-supported tiers is being replaced by the hard reality of operational efficiency. For the remainder of 2026, the industry will likely be defined by three key themes:
- Platform Integration: The success of the Disney/Hulu and Paramount/Max mergers will serve as a bellwether for the rest of the industry. If these consolidations result in improved ad performance and easier measurement, other players will likely follow suit.
- Data Maturity: The reliance on retail media networks and clean room solutions will continue to grow as advertisers demand more "deterministic" proof of ROI. The era of blind faith in reach-based metrics is rapidly closing.
- The Return of the "Bundle": While the digital age promised an à la carte revolution, the market has circled back to a bundled model. The challenge for marketers will be navigating these new, larger ecosystems without losing the agility that digital advertising once promised.
Ultimately, the CTV landscape of 2026 is one where the "fragmentation era" is giving way to a "consolidation era." Advertisers who can successfully navigate these shifts—by leveraging new measurement tools and prioritizing strategic content alignment over raw CPM volume—will be the best positioned to capture the value of the next generation of television. The transition will not be without its hurdles, but the move toward more stable, transparent, and outcome-oriented environments represents a net positive for the long-term health of the digital advertising economy.
