Cannes 2026: $25B+ in ad-tech deals reshape CTV landscape

The consolidation wave signals that scaled CTV assets are being absorbed faster than new ones can emerge, creating a supply crunch that rewards sellers with premium valuations. Fox-Roku, Walmart-Vibe, and Publicis-LiveRamp each represent a different buyer archetype — media company, retailer, and agency — all converging on the same thesis: owning the measurement and performance layer is now table stakes. Public ad-tech multiples remain depressed while private deals command outsized premiums, widening the valuation gap between public and private market participants. Watch whether Roku's open-platform commitment survives regulatory scrutiny and post-close integration, as that promise underpins the deal's $400M synergy target.

The Cannes dealwave builds on a consolidation cycle that accelerated earlier in 2026. Fox announced its $22 billion Roku acquisition on June 15, per AP News, valuing Roku at $160 per share in cash and stock; the combined entity would become the third-largest U.S. television player by viewing share, with Fox shareholders owning approximately 73% of the merged company. Roku CEO Anthony Wood is set to join Fox's board, and the companies expect roughly $400 million in run-rate cost synergies, per the official Roku newsroom announcement.

Walmart's Vibe.co acquisition, announced June 23, extends the retailer's CTV strategy beyond its $2.3 billion Vizio purchase in 2024. AdExchanger reported the deal price at approximately $1.4 billion, citing The Wall Street Journal, while Digiday's sources placed it north of $1 billion. Vibe.co brings more than 10,000 SMB and mid-market advertisers to Walmart Connect, a cohort the retailer has been targeting since requiring Vizio device owners to log in with Walmart accounts in March 2026.

Publicis's $2.2 billion LiveRamp deal, announced May 17, represents a 29.8% premium to LiveRamp's closing price, per Bloomberg. Publicis framed the acquisition around "agentic" AI capabilities and data co-creation, raising its 2027-2028 growth targets accordingly. Meanwhile, AppsFlyer's $1 billion-plus investment round, reported by Axios on June 22, values the measurement company at $2.7 billion post-money, with Google, Meta, Moloco, and Unity each taking minority, non-controlling stakes. CEO Oren Kaniel told Axios the company intends to go public, though it shelved IPO plans last year due to 10-15% annual growth rates.

The broader pattern, as AdExchanger noted, reflects an industry where buyers increasingly want closed-loop attribution between ad spend and commerce outcomes — a demand that makes performance TV platforms and measurement infrastructure among the most strategic acquisition targets.
