Walmart buys Vibe.co for $1.4B, signaling CTV self-serve vs Meta, Google, Amazon

Ad industry insiders at Cannes Lions are buzzing because Walmart is reportedly paying $1.4 billion to acquire French adtech firm Vibe.co, according to the WSJ. Walmart declined to comment on the terms. The size of the price tag is turning heads, especially because Vibe said its valuation was $410 million this past September, when it last raised capital.

So what does that mean in plain English? Walmart wants to become a major force in connected TV (CTV) and streaming TV advertising, and it’s doing it by buying technology that can make buying streaming TV ads as simple as using Google or Meta. Walmart’s acquisition is framed by industry chatter as intent to rival ad giants like Meta, Google, and Amazon, and it fits with a broader strategy: capture more of the streaming TV ad market by tying exposure to commerce and sales outcomes.

This is not happening in a vacuum. Walmart already has adjacent building blocks in place. In 2024, it acquired TV company Vizio, a move that helped it tap into TV ad budgets and demonstrate that its expanding ad ecosystem could drive sales. Now, Vibe is positioned as another step in the same direction, aimed at improving how ads are bought and managed, especially for streaming TV.

There’s also a budget reality behind the hype. BI sister company EMARKETER estimates that Walmart’s ad business will generate $8.23 billion in worldwide ad revenue this year. Compare that with EMARKETER’s forecasts for Meta at $243.46 billion, Google at $239.54 billion, and Amazon at $82.07 billion. Walmart is smaller by orders of magnitude, but the acquisition suggests it is trying to scale fast by targeting a segment that big-platform ad ecosystems sometimes struggle to serve with the right level of simplicity: small- to medium-sized businesses (SMBs).

Matt Barash, chief commercial officer of Nova, told BI that Vibe’s core promise matters because the next wave of CTV growth will not come only from Fortune 500 budgets. Barash argues that SMBs want TV-scale reach with digital-style accountability, and Walmart is assembling the pieces to connect exposure, commerce, and sales outcomes in a way traditional television never could. In other words, Walmart is betting that “CTV but easier” will bring in advertisers who want reach, but do not want to deal with complex, labor-heavy buying.

And there is a second order effect embedded in how the deal is structured, even though Walmart declined to comment on terms. Andreas Roell, CEO of M&A advisory firm Evros Group, told BI the key with this transaction is Walmart committing to self-service. The logic is straightforward: self-service ad buying can unlock more revenue because it requires less hands-on support. Roell also framed Walmart’s approach as using hindsight, pointing to Amazon’s evolution. Amazon spent years frustrating advertisers with a powerful but often clunky adtech stack before overhauling it around 2022, and that cleanup helped cement Amazon’s ad dominance.

That matters for anyone evaluating competitive strategy in adtech. When one buyer figures out how to reduce friction for advertisers, rivals do not just lose deals. They can lose entire categories of spend, because advertisers standardize around the easiest workflow. Roell added that Amazon’s efforts, including potentially aggressive moves to undercut competitors on fees, made life harder for rivals like The Trade Desk. If Walmart is moving in a more intentional, structured way, it’s not just acquiring Vibe for its tech. It is signaling it wants a cleaner path to scaling CTV adoption.

There’s one more detail Cannes attendees can’t stop talking about: Vibe was known for provocative marketing. CEO Arthur Querou previously dressed up as Sydney Sweeney to emulate an American Eagle ad with the tagline “Streaming TV has great leads.” (The promotional concept included Sydney Sweeney lookalike elements and the “great jeans” framing.) Whether that style survives Walmart’s brand compliance culture is an open question, but the bigger point is that Walmart appears to be buying into a company that already understood how to make streaming TV advertising feel direct, not abstract.

For executives, board members, and investors, the strategic stake is simple: Walmart is using a mega-deal to accelerate its move from retail-ad adjacency into a more scalable CTV advertising machine. The question now is whether self-service CTV buying, powered by Vibe’s “digital-style” simplicity, can pull in enough SMB budget to meaningfully change the competitive map. If it works, peers will feel it quickly, not years from now, because advertisers do not need a better pitch. They need a better process.
