As we close out 2025, it’s clear this wasn’t just another year of incremental growth – it was a year of structural re-architecture. The marketplace model has moved from being a “digital shelf” to an integrated, AI-driven, and internationally fluid ecosystem. For sellers, the “Bigger Picture” of 2025 is the transition from managing listings to managing complex, cross-border value chains.
1. Agentic Commerce: The War for User Choice (Perplexity vs. Amazon)
In 2025, AI agents became transactional. While OpenAI’s deep integrations with Shopify and Stripe created a seamless “Headless Commerce” backend, the year ended in a legal showdown. In November 2025, Amazon sued Perplexity, alleging that its “Comet” shopping bots were covertly accessing accounts and bypassing security to automate purchases. Perplexity countered, framing the lawsuit as a threat to “user choice” and the right to have an AI assistant.
- The Bigger Picture: We are seeing the first major conflict between “Closed Gardens” (Amazon) and “Open Agents” (Perplexity). The battle is over who owns the customer relationship: the platform or the AI agent.
- 2026 Impact: Success in 2026 will depend on your “Product Knowledge Graph.” Brands must decide whether to optimize for platform-specific AI (like Amazon’s Rufus) or universal agents that may soon be legally restricted.
2. The Regulatory Wall: The End of “Tax-Free” Imports
The dominance of Temu and Shein met its match in EU regulation. In December 2025, the EU finalized a €3 flat-rate custom duty on all small parcels from non-EU countries, effective July 1st, 2026. This complements the French Anti-Fast Fashion Law (passed June 2025), which introduces a €5 eco-tax per item and a total ban on fast-fashion influencer marketing starting January 1st, 2026.
- The Bigger Picture: The “Wild West” of tax-free, direct-from-China shipping is officially ending. The EU is re-asserting sovereignty to protect local, compliant competition.
- 2026 Impact: Domestic sellers will see a “fairness dividend.” As the €3 fee and €5 eco-tax narrow the price gap, delivery speed and local compliance will replace “absolute lowest price” as the key conversion drivers for 2026.
3. The TikTok Shop Invasion: Polarized Realities & Hard Data
The 2025 rollout of TikTok Shop in Central Europe (DE, FR, IT) moved past the hype and into hard data. In France alone, the platform generated €53 million in October 2025 with over 35,000 active shops. However, the experience was highly polarized. While brands like Blissim saw record engagement, About You pulled its integration just four weeks after the June launch, citing a mismatch between the platform’s high operational intensity and their existing fulfillment structures.
- The Bigger Picture: TikTok is successfully attacking Amazon’s convenience moat with “Fulfilled by TikTok,” but it requires a fundamental shift in seller DNA – from static listings to high-frequency content creation.
- 2026 Impact: “Discovery-led Commerce” is now a primary consumer habit. In 2026, the gap will widen between “content-ready” brands and traditional retailers who fail to entertain.
4. The Internationalization Paradox: Expansion vs. Retreat
2025 saw a massive wave of cross-border growth. OnBuy expanded into 12 European countries in September, and B&Q (Kingfisher) made a surprise move in November 2025 by opening its UK marketplace to German sellers, offering a specialized “Cross-Border Turbo” for DIY brands. The consolidation of the European fashion market was finalized on November 6th, 2025, with the legal squeeze-out of About You by Zalando. Conversely, the year proved that scale isn’t everything: Wayfair completed its exit from the German market in January 2025 to focus on profitability in its core strongholds.
- The Bigger Picture: Internationalization is no longer about geographic “land grabs” but about “unified scale.” Platforms are either going all-in on a pan-European model or retreating to core markets.
- 2026 Impact: For sellers, the “barrier to entry” for cross-border trade has dropped, but the competition is now truly global and focused on localized excellence.
5. Platform Consolidation: Quality over Quantity
The consolidation wasn’t just corporate, but also internal. Amazon’s “Project Bend the Curve” led to the removal of billions of low-quality or inactive listings to save on massive AWS infrastructure costs. Simultaneously, platforms like Otto increased seller fees to prioritize high-volume, professional partners over low-margin churn.
- The Bigger Picture: 2025 was the year marketplaces stopped chasing “infinite shelf space” and started prioritizing “curated quality.” They are cleaning up their databases to reduce the “noise” for both customers and AI crawlers.
- 2026 Impact: Marketplace SEO is shifting. It’s no longer about keyword volume but about performance health, returns ratios, and delivery reliability.
6. Circular Economy 2.0: Re-Commerce as a Standard
Sustainability has moved from a marketing claim to a business pillar. Vinted became a dominant force in the broader retail conversation, while Kaufland and Back Market launched integrated “Second Life” programs, allowing customers to trade in electronics and appliances directly on the platform.
- The Bigger Picture: “Circular as a Service” is becoming a standard marketplace feature. Consumers now expect a “sell back” button next to the “buy” button.
- 2026 Impact: Brands must develop a “Second Life” strategy. In 2026, marketplaces will likely reward (or require) products that are certified as repairable or part of a formal buy-back program.
