CTV's Consolidation Wave Bought Pipes, Data, and Measurement. The Missing Piece Is the Ad Itself.

Six deals. Tens of billions of dollars. And the most critical layer in connected TV advertising still doesn't have an owner.

Connected TV is the fastest-growing segment in advertising. U.S. advertisers are expected to spend nearly $38 billion on CTV this year, with double-digit growth projected through the end of the decade. That kind of trajectory attracts capital. And in CTV, capital has been moving through M&A at a pace the industry hasn't seen before.

In December 2024, Walmart closed its $2.3 billion acquisition of Vizio, absorbing the smart TV maker's operating system and ad platform into Walmart Connect. In September 2025, Magnite acquired streamr.ai, an AI-powered platform that helps small and mid-sized businesses create and launch CTV campaigns. Three months later, Pinterest announced a $450 million deal for tvScientific, a performance TV measurement platform, and closed it by February 2026. In May, Viant picked up TVision for $40 million to add real-time attention signals to its CTV stack. And in June, two more: Fox announced a $22 billion acquisition of Roku, combining its live content portfolio with the largest CTV platform in the U.S., and Walmart came back for Vibe.co, the self-serve CTV ad platform it's folding into Walmart Connect.

That's six acquisitions in roughly 18 months. The combined price tag exceeds $25 billion.

What they're all buying

Read the press releases and the pattern becomes clear. Every deal is buying some combination of the same three assets: distribution pipes, self-serve buying interfaces, and measurement infrastructure.

Walmart bought Vizio for its TV operating system and first-party shopper data. Pinterest bought tvScientific for outcome-based attribution. Fox bought Roku for its 100 million-plus streaming households and ad platform. Magnite bought streamr.ai for self-serve campaign tools. The specifics differ, but the thesis is the same: build a closed-loop stack that can take an advertiser from targeting to transaction inside a single platform.

The common thread running through all of it is what the industry has started calling "performance TV." The term describes a CTV buying model that looks more like paid search and social than traditional television: self-serve interfaces, measurable outcomes, and access for advertisers who couldn't previously afford to be on TV. The measurement infrastructure has improved so fast that some advertisers have already overcorrected toward lower-funnel metrics and stopped funding the demand generation that makes CTV work as a full-funnel channel.

"CTV is one of, if not the biggest growth engines in advertising," says Alex Persky-Stern, CEO of Waymark, an AI-powered video creation platform that partners with major media companies including Comcast, Fox TV Stations, and Spectrum Reach. "In a land grab like this, M&A is a natural strategy."

The acquisitions are chasing two things at once. The first is access to advertisers and the sales engines that serve them. The second, and more strategically interesting one, is the mid-market and SMB segment that has historically lived on Meta and Google. Performance TV is code for that segment: brands spending against measurable outcomes, looking for channels beyond social and search, with budgets that don't support traditional TV buying processes.

"CTV has created a market for a type of advertiser that never existed on television before," Persky-Stern says. "Someone who's paying attention to real attribution, real sales data, the way they would on any digital channel. That's an entirely new demand pool, and every platform wants to be the one that captures it."

The layer nobody acquired

Look at the six deals again. Pipes, platforms, measurement. Self-serve interfaces, data, attribution. All of it matters. None of it solves the problem that actually keeps mid-market advertisers off television.

Creative.

A performance advertiser on Meta can upload a product photo and have an ad running in minutes. A CTV campaign, on the other hand, requires broadcast-quality video. For an advertiser spending $5,000 or $10,000 a month, the production cost of a single TV-grade spot has historically exceeded the entire media budget. That bottleneck hasn't gone away because someone built a better self-serve buying interface. "What you've seen in the acquisitions so far is more focused on the platforms themselves. Do you have a self-serve platform? Do you have the pipes set up? Do you have the measurement? But the really obvious missing piece for all of those is creative," says Persky-Stern.

The platforms know it. Every major CTV player is thinking about creative infrastructure, and the first moves along the buy-build-partner spectrum are already visible. MNTN built QuickFrame AI, an in-platform creative tool that generates TV spots for brands without production resources. Vibe.co built Vibe Studio, an AI video editor that now produces more than 10% of the ads running on its platform. Comcast added an AI-powered video generator to Universal Ads, the cross-publisher self-serve platform it launched in early 2025.

Magnite's acquisition of streamr.ai is the closest any deal has come to buying a creative-first capability. But across the board, creative remains the layer that every consolidating stack needs and none of them fully controls.

Why creative matters twice for performance CTV

Creative isn't just a production problem. On performance channels, it's an optimization problem.

On Meta and Google, the winning brands aren't running a single ad. They're running dozens of variations, testing copy, imagery, hooks, and calls to action against live performance data. The creative itself becomes the primary lever for improving cost-per-acquisition and return on ad spend.

CTV is moving toward the same model. But the economics only work if producing a new variation doesn't cost $50,000 and take three weeks. "Creative testing and iteration and optimization is a huge part of the game on existing performance channels," Persky-Stern says. For the mid-market and SMB advertisers that every CTV platform is now chasing, that means creative has to be fast, affordable, and built for volume.

That creates a structural opportunity for creative infrastructure that operates independently of any single platform. A walled-garden approach to creative, where each CTV stack builds its own in-house tools, fragments the market and limits advertisers to one ecosystem's capabilities. A platform-agnostic creative layer that connects across multiple stacks lets advertisers produce, test, and optimize video wherever they're buying.

As State of Brand previously reported, Walmart's acquisition of Vibe.co raised questions about what happens when a self-serve CTV platform built for open access gets pulled inside a retail media wall. The creative layer faces the same tension. Build it inside the stack and it only works in one place. Build it independently and it works everywhere.

The next round isn't about pipes

The first wave of CTV consolidation has been about assembling the infrastructure for performance TV: the platforms, the data, the measurement. That wave isn't over. The Fox-Roku deal alone signals that the land grab for streaming households will continue well into 2027.

But the next critical piece is different. The platforms, the pipes, and the self-serve interfaces are prerequisites. They get advertisers to the door. Creative is what gets them through it.

Every consolidating CTV stack will need to answer the creative question. Some will build, some will buy, some will partner. The deals that close over the next 12 months will tell us which path wins.
