Digital advertising in France: the market soars by 12% in the first half of 2026

Digital advertising in France is not in crisis. In the first half of 2026, market revenues reached 6,689 billion euros, up 12 % year on year, according to the 36th Observatoire de l’e-pub presented in mid-July 2026 by the SRI and UDECAM with Oliver Wyman. Behind this record figure lies a deep reshuffling of usage, which every advertiser and agency should decode before allocating their budgets for the end of the year.

A market of nearly 6,7 billion euros in six months

Growth remains strong, but it is no longer distributed in the same way among the main levers. Search keeps its top spot, while Social is catching up at high speed. Here is the snapshot for the semester :

• Search : 2,74 billion euros, or 41 % of the market and an increase of 12 %.
• Social : 2,22 billion euros (33 %), up 16 %, the most dynamic channel in volume.
• Display : 1,25 billion euros (19 %), +10 %.
• Affiliation, emailing et comparateurs : 481 million euros (7 %), only +4 %.

The message is clear: advertising revenue concentrates where attention is, namely on social platforms and search engines. For older channels like emailing or affiliation, growth is slowing significantly.

Social video, the true engine of growth

If one format pulls the entire market upward, it is short-form video. Video on social networks now weighs 1,42 billion euros, jumping 31 % year on year, and alone represents 64 % of Social revenues. On the Display side, video generates 790 million euros (+15 %), or 63 % of that channel, and connected television (CTV) already captures more than half of video revenues. In other words, the advertising screen of 2026 is mobile, vertical and increasingly viewed on a connected TV.

Retail media, the other quiet accelerator

Less visible to the general public, retail media — advertising sold by merchant sites to their own audiences — reaches a new milestone with 775 million euros in revenues, up 18 %. Its search component (retail search) even jumps 24 %. For players in e-commerce and online shopping, this figure confirms that purchase data has become an advertising asset in its own right, able to compete with traditional ad networks.

What these figures change for advertisers and agencies

This double-digit growth hides a growing dependence on a few giants. European players account for only 17 % of the market (down one point), with growth limited to 4 % while the whole market grows by 12 %. Concretely, the bulk of budgets flows to a very small number of international platforms. For an SME or an agency in communication and marketing, three lessons emerge :

• Test short-form video without delay: this is where performance plays out and costs remain manageable for small budgets.
• Include retail media in the media plan as soon as you sell a product, rather than reserving it for big brands.
• Diversify your channels so as not to depend on a single network, a common-sense reflex for any young company or startup.

Outlook remains promising. “Despite an unfavorable macroeconomic context, we anticipate growth of the French digital advertising market of around 11 % in 2026,” summarizes Maïté Dailleau of Oliver Wyman. Over the full year, the market is expected around 13,9 billion euros. Enough to confirm that digital remains advertisers’ first instinct, provided they follow attention where it migrates.
