JD Sports Leans on 'Sharper Marketing' and AI as H1 Sales Dip
JD Sports posted a half-year sales dip to £5.89bn but framed 'sharper marketing' and faster AI-driven measurement as its growth lever — and promoted Mike Grimes to group CMO.
Marketing as the Growth Lever in a Downturn
JD Sports' half-year results (26 weeks to 1 August 2026), reported on 23 September 2026, showed group sales down 0.7% to £5.89bn, like-for-like sales off 2.8%, and gross margin at 46.8%. Despite the slide, the retailer credited "sharper marketing activations" for lifting brand awareness, notably in North America.
The company said it is accelerating AI use to measure marketing effectiveness while doubling down on its core 16-24 audience. Separately, 18-year veteran Mike Grimes was promoted to group CMO on 16 September 2026.
Why This Is a Notable Signal
It is increasingly common for retailers to cut marketing when sales soften. JD Sports is publicly doing the opposite — naming marketing and AI measurement as the route back to growth. That is a confidence signal, and one CFOs elsewhere will notice.
The AI angle matters most. "Accelerating AI to measure marketing effectiveness" is code for closing the accountability gap that has long made marketing budgets vulnerable. If JD can prove ROI faster, it can defend and grow spend.
What Marketers Should Take From It
The playbook here is defensible investment: protect brand spend during a dip, but pair it with hard measurement so the board can see it working. Marketing that cannot prove its effect is the first thing cut; marketing that can becomes untouchable.
Our read: watch Mike Grimes. A newly-installed CMO inheriting a "marketing-led growth" mandate during a downturn is under real pressure to convert that narrative into numbers.

Cutting marketing in a downturn is the easy call and usually the wrong one. What impresses me about JD is pairing brand investment with faster AI measurement — that's how you make a budget board-proof. Prove the effect, and marketing stops being the first thing cut. — Daniel Nikolla, Founder of Merx Marketing
Protecting brand spend in a downturn only works if you can prove its effect — measurement is what makes marketing budgets defensible.
If sales dipped tomorrow, could you prove your marketing is worth protecting?
