How I Turned Amazon Trends into Vinted Gold (and Vice Versa)

The biggest mistake most sellers make? Treating each marketplace as an isolated ecosystem. The reality is that trends flow between platforms like water—and if you know how to read the currents, you can surf the wave from one market to another.

This isn't about copying products; it's about understanding how consumer behavior shifts across different platforms and timing your moves accordingly.

The Cross-Market Intelligence Framework

After analyzing over 500 cross-market opportunities, I've identified a systematic approach that consistently identifies profitable arbitrage opportunities.

The 72-Hour Rule

Trends don't appear simultaneously across all platforms. There's typically a 24-72 hour lag between when a trend hits one marketplace and when it appears on others. This window is your competitive advantage.

The Correlation Matrix

Not all trends transfer equally. I've mapped the success rates:
