Reach vs Effectiveness: What Marketing Spend Is Worth in 2026

Every downturn and every technology shock forces the same question onto marketing budgets: what is actually worth paying for? In 2026 the answer is consolidating around an unglamorous pairing, provable effectiveness and genuine cultural relevance, and away from the thing brands once bought by default, sheer reach. For founders, operators and the investors who back them, this is more than a media-planning footnote. It changes what a brand is worth, and what kind of spending deserves to be called an investment rather than a cost.

When reach becomes a commodity

The logic is straightforward once reach is cheap. When attention can be bought at scale, simply being seen no longer differentiates a company. Two things still do: evidence that marketing moves the business, and a place in culture that audiences actually choose to engage with. Capital is migrating accordingly, toward effectiveness that can be measured and partnerships that buy credibility rather than mere impressions. Cannes Lions 2026 made the reallocation easy to observe. The clearest signal was structural: AB InBev opened the festival as the first company ever named Creative Marketer of the Year three times, having collected 183 Lions between 2021 and 2025. That is the return on a deliberate, decade-long investment in marketing culture, and the lesson is that brand-building treated as a disciplined capability, rather than a discretionary expense, compounds.

Effectiveness becomes the headline metric

The most telling award of the week sat in the Creative Effectiveness category, which exists to reward business results rather than craft. Its Grand Prix went to AXA's Three Words, recognised for delivering both short and long-term business impact, proof that purpose and performance are not opposing line items when the work is built to do a measurable job. For investors reading a brand's marketing, the implication is to stop accepting awareness as the terminal metric. The question that separates a defensible marketing investment from a vanity one is whether the spend can be traced to a commercial outcome, and increasingly the strongest brands can show their working.

Partnerships as a credibility purchase

The second migration of spend is toward partnerships that buy cultural standing money cannot otherwise manufacture. The Entertainment Grand Prix went to Adidas' Original Forever, built around the reunion of the Gallagher brothers and the brand's long association with Oasis, reactivating decades of loyalty while recruiting new fans. This is a different transaction from a celebrity endorsement. The brand is not renting fame, it is investing in a genuine cultural relationship with its own history, which is far harder for a competitor to copy. The most durable partnerships are rooted in something authentic to the brand, not bolted on for borrowed relevance.

The most valuable brands leaving Cannes this year were not the ones that spent the most. They were the ones that knew the difference.

Sport is the new prime real estate

If one category captured where partnership budgets are flowing, it was sport, described at the festival as the closest thing the culture now has to a shared religion. Two winners showed how the thesis is evolving beyond logo placement. The Entertainment Lions for Sport Grand Prix went to The Thousand Sponsors of Muni for Peru's Club Deportivo Municipal, which redesigned the team jersey into a grid of 1,000 spaces sold to fan-owned businesses through micro-donations, turning sponsorship into a community ownership model. In Creative Commerce, Wisła Kraków's AI-driven Lucky Fan Index tied fan emotion to commercial results, lifting match attendance by 42% to its highest level in the league. The smart money in sport is buying participation and data, not just visibility.

How to value a brand in 2026

Put the pieces together and a clear framework emerges. The brands attracting and rewarding capital are those that can demonstrate effectiveness, own a credible cultural position, and convert audiences from spectators into participants. Each is a moat: a measurable marketing engine is hard to replicate, an authentic cultural relationship cannot be bought overnight, and a participatory community is far stickier than a passive audience. Reach, by contrast, is available to anyone with a budget, which is exactly why it no longer commands a premium.

The takeaway for 2026

For founders and operators, the practical move is to reclassify brand spending on the same terms an investor would. Spending that produces a traceable business result, deepens a genuine cultural relationship, or builds an owned community is an investment that compounds and should be protected even when budgets tighten. Spending that buys nothing but temporary visibility is a cost, and should be treated as one. The most valuable brands are simply the ones that know the difference.
