The ad industry's annual Cannes Lions festival once again turned the French Riviera into a week of panels, yacht parties and deal-making. This year, two subjects dominated the conversation from the Croisette to the Carlton terrace: artificial intelligence and sports.

According to Business Insider's reporting from the festival, AI and sports were the hot topics among advertisers, agencies and platforms in attendance. The industry's biggest annual gathering has a track record of chasing whatever theme Wall Street and the tech press have spent the prior twelve months amplifying, and 2025 fit the pattern.

AI has now moved from experimental pitch to standing agenda item. Advertisers want to know what it costs, what it actually produces, and whether the output can be measured. Sports, meanwhile, continues to command premium pricing as one of the few environments where large live audiences still gather on a predictable schedule. Marketers keep paying up for that certainty, and the festival reflected it.

But Business Insider's report carries a sharper observation in its headline, and it is the detail that stands out from the usual Riviera coverage: attendees were notably reluctant to discuss "brand safety." The phrase, once a fixture of every ad-tech panel and platform pitch, has apparently become something participants would rather not raise at all.

That reticence says something about where the industry currently stands. Brand safety grew into a large commercial category after the 2017 YouTube ad boycott, when major advertisers pulled spend over placement next to extremist content. Since then, verification vendors, measurement firms and platforms have built entire product lines around the promise of keeping ads away from harmful material.

At a festival now organized around AI hype and sports rights inflation, the silence on brand safety suggests the topic no longer sells — or that the questions it raises have become inconvenient. AI-generated content, platform content moderation failures and the spread of synthetic media all raise brand safety questions that grow harder, not easier, to answer. The absence of those questions from the Cannes agenda is itself the story.

Business Insider did not detail which specific deals, product launches or panel discussions drove the AI and sports focus, and no pricing figures or attendance numbers appeared in the report. The substance of the coverage is directional rather than granular: two topics up, one topic down.

For operators tracking where ad budgets and vendor roadmaps are heading, the signal is still useful. Festival chatter tends to foreshadow the next cycle of procurement priorities. If AI and sports took the speaking slots, expect those categories to take a growing share of ad spend conversations through the rest of the year.

And if "brand safety" has become the phrase nobody says out loud at Cannes, watch for it to reappear under a different name — rebranded, repackaged, and priced accordingly — once the current cycle turns.
