The global fashion e-commerce market is experiencing a period of policy-driven volatility and structural transformation. U.S. tariff reform and the rapid adoption of GenAI are polarising valuations across business models, while M&A activity rebounds, driven by strategic consolidation, PE re-engagement, and a cautiously positive outlook into 2026.

Executive Summary

1. Fashion eCommerce has entered a structural reset.

The 2025 U.S. tariff reform – including the removal of the De Minimis rule – has fundamentally rewritten cross-border economics, forcing a rapid repricing of business models across the sector.

At the same time, GenAI is transforming how consumers discover and buy fashion, shifting demand away from traditional search into AI-driven interfaces.

Together, these forces are creating a clear divide:

• Asset-light platforms are outperforming
• Inventory-heavy models are under pressure
• Luxury remains structurally resilient

Public markets and M&A activity are already reflecting this divergence – and the gap is widening.The 2025 U.S. tariff reform – including the removal of the De Minimis rule – has fundamentally rewritten cross-border economics, forcing a rapid repricing of business models across the sector.

2. A Structural Reset in Economics

Tariffs have moved from background noise to a defining force. The removal of the De Minimis exemption means all imports into the U.S. are now subject to duties – dismantling a core advantage for cross-border eCommerce models.

The impact is immediate:

• Margin pressure for inventory-led retailers
• Pricing pass-through across premium and luxury
• Accelerated supply chain reconfiguration

Business model resilience is now the key differentiator.

3. GenAI Is Rewiring Demand

GenAI is fundamentally changing how fashion is discovered and purchased.

• Up to 80% of users rely on AI-generated search outcomes
• Product discovery is rapidly shifting into AI interfaces
• AI-driven journeys deliver materially higher conversion rates

This reshapes the competitive landscape:

• Fewer brands capture visibility
• Customer journeys compress into “zero-click” decisions
• Platforms increasingly control the transaction layer

This is a winner-takes-most dynamic – driven by algorithmic visibility.

4. M&A: From Pause to Precision

After a slowdown in 2025, deal activity has begun to recover, with Q4 marking a clear inflection point.

M&A is becoming more targeted, focused on:

• Technology acquisition (AI, data, CX capabilities)
• Supply chain control (tariff mitigation, sourcing flexibility)
• Platform scale (consolidating fragmented markets)

Private equity is re-engaging selectively, targeting scalable platforms and dislocation-driven opportunities.

The market is shifting toward precision consolidation.

5. Valuation: A Market Dividing

Valuations are diverging sharply by business model:

• Marketplaces & aggregators: re-rating on scalability and efficiency
• Luxury brands: resilient, supported by pricing power
• Inventory-led eCommerce: de-rating on margin pressure and risk

Investor focus has shifted decisively toward profitable, scalable growth.

Resilience is now being priced – not just growth.

Key Takeaways for Investors and Owners

• Tariffs are structurally reshaping the sector
• GenAI is redefining demand capture and customer journeys
• Clear winners and losers are emerging by business model
• M&A is accelerating with a more targeted, strategic focus
• Valuations are polarising around quality and resilience
