The Retail Technology Show wrapped its two-day run at London's ExCeL on Wednesday, and if there was a single theme that cut through the 450+ exhibitor booths, 125 speaker sessions, and endless conference floor conversations, it was this: the AI hype cycle is over. The execution cycle has begun.

RTS 2026 — complete with a new disco theme that organizers used to signal the industry should be celebrating innovation, not fearing it — drew more than 15,000 senior retail professionals from across Europe, making it the largest edition of the show to date. And the conversations that dominated the floor were markedly different from a year ago.

From "What Can AI Do?" to "What's It Actually Doing?"

The shift was palpable. Where the 2025 show was heavy on generative AI demos and proof-of-concept pitches, this year's programming focused on AI maturity — helping retailers move from experimentation to production deployment across store operations, workforce management, marketing, and inventory optimization.

Marks & Spencer chairman Archie Norman was among the headline speakers, alongside Sephora UK's Sarah Boyd and TALA founder Grace Beverely. The presence of retail operators — not just technologists — in the keynote lineup signaled a deliberate pivot: the audience wanted to hear from people running stores, not just people building software for them.

The Exhibitor Floor: AI Everywhere, But Specific

The innovation showcase was the show's largest ever, featuring a dedicated zone for 16 scale-up companies alongside the major platform vendors. A few announcements stood out:

Vusion spotlighted its vision for the connected shelf — digital shelf labels that go beyond price display to include real-time inventory data, promotional triggers, and integration with mobile shopping apps. With Walmart already rolling digital shelf labels across 5,200 U.S. stores by 2027, the European market is watching closely.

Invent.ai unveiled multi-agentic capabilities for inventory optimization — AI agents that don't just forecast demand but autonomously coordinate across suppliers, warehouses, and stores to adjust orders in real time.

Logile showcased connected store operations platforms that use AI-powered workforce scheduling alongside task management and real-time store execution data.

The New Addition: Cyber and Loss Prevention

New for 2026, RTS added a Cyber & Loss Prevention Zone featuring companies from the intelligence and digital forensics space, including ESET and First Response Europe. The addition reflects a growing recognition that as retail technology stacks get more complex — and more AI-driven — the attack surface grows with them.

Retail cyber losses have been a recurring theme in 2026, with Hasbro's recent cyberattack-related earnings delay being just the most visible example. The zone's debut at RTS suggests the industry is beginning to treat cybersecurity as a core retail operations concern, not an IT afterthought.

What K-Supermarket Showed About the In-Store Future

One of the more novel exhibits came from Finland, where K-Supermarket has been piloting conversational AI on in-store digital billboards across three cities. Shoppers walk up, speak to the display, and get personalized recipe ideas based on what's in stock. It's a small-scale pilot, but it represents the kind of ambient, voice-first retail experience that many at RTS see as the next frontier beyond chatbots and apps.

The Takeaway

The Retail Technology Show has always been a barometer for where European retail tech is headed. In 2025, the question was whether AI would transform retail. In 2026, the question has shifted to which retailers will be first to operationalize it at scale — and which will still be running proofs-of-concept when the market moves past them.

If the exhibitor floor is any guide, the answer is becoming clearer: the retailers investing in AI as an operating layer — not a feature — are pulling ahead. The rest are running out of runway.
