Key takeaways
- European e-commerce nears €961bn in 2026, but growth is uneven across markets and categories.
- New parcel taxes and customs friction squeeze thin-margin and cross-border models first, accelerating consolidation.
- 30% of French shoppers — 64% of under-25s — say AI already influences their purchases.
- Fashion is in free-fall: down 17.6% in-store and 15.9% online in September 2026, with no digital cushion.
- Winners treat parcel economics, AI-driven discovery and category discipline as one connected system.
European commerce is in a strange place in 2026. On paper, the numbers look healthy: B2C online sales climbed from €842bn in 2024 to €911bn in 2025, and the market is on track to brush €961bn this year. Yet beneath the growth curve, the ground is shifting. Parcel economics are being rewritten, AI is quietly rerouting purchase decisions, and entire categories like fashion are falling off a cliff. Growth is no longer evenly distributed — and that is the real story for anyone running an online business.
The headline growth hides a redrawn map
A +8.5% uplift in France and roughly +7% across Europe (around +4% once inflation is stripped out) sounds reassuring. But aggregate figures flatten the reality on the ground. The map of opportunity is being redrawn market by market and category by category. Some regions and verticals are absorbing most of the gains, while others are contracting hard.
The clearest warning sign is fashion. In September 2026, French apparel retailers tracked for the Alliance du Commerce saw in-store revenue drop 17.6% year on year — and crucially, digital failed to cushion the blow, falling 15.9%. For years, the comfortable assumption was that e-commerce would offset weak physical retail. That safety net is gone. When online declines alongside the store, the problem is demand, not channel.
Why parcel costs are the new battleground
The quieter but more structural shift is in logistics. As cross-border selling expands and regulators look harder at the flood of low-value imports, parcel-level taxes and tighter customs handling are moving from rumour to roadmap. Every small package now carries administrative and fiscal weight that didn't exist a few years ago.
For merchants, this has three immediate consequences:
- Thin-margin models get squeezed first. Ultra-low-price cross-border arbitrage depends on near-zero parcel friction. Add a per-parcel levy and the maths collapses.
- Returns become a strategic cost centre. With returns management tooling maturing, the winners will treat reverse logistics as a profit lever, not an afterthought.
- Consolidation accelerates. Scale buys better carrier rates, smarter fulfilment placement and the ability to absorb new fees. Smaller independents increasingly plug into larger platforms or specialist 3PLs rather than going it alone.
AI is already influencing the checkout
Logistics isn't the only force reshaping commerce. AI has crossed from back-office novelty into the purchase decision itself. An Ipsos study for Joko found that 30% of French consumers say AI already influences their buying — rising to 64% among 18–24 year-olds. That is not a future trend; it is current behaviour.
Meanwhile the tooling ecosystem is racing ahead, with the first wave of agentic commerce services — software agents that research, compare and increasingly transact on a shopper's behalf. The implication is profound: if an AI assistant is shortlisting products, your merchandising, structured data and review signals matter more than your banner creative. Optimising for machines that buy is becoming a discipline in its own right.
What this means for your 2026 strategy
Put the threads together and a clear operating picture emerges. Growth exists, but it rewards operators who defend margin and earn visibility in AI-mediated discovery.
- Model your true landed cost per parcel. Build new taxes, returns and customs handling into your unit economics now — not after they bite.
- Audit your AI readiness. Clean product feeds, rich structured data and credible reviews are what agentic tools consume. Invisible data means invisible products.
- Rethink category bets. If you're exposed to fashion or other contracting verticals, diversify assortment and double down on retention over discount-led acquisition.
- Decide on consolidation deliberately. Choose whether to scale, partner or specialise — passivity is the one option that loses.
The merchants who thrive through 2026 won't be the ones chasing the €961bn headline. They'll be the ones who treat parcel economics, AI-driven discovery and category discipline as a single, connected system — and act before the rules finish changing.
