Born out of conversations that started in Paris and evolved through Milan and Toronto, GDX is not just another initiative—it’s a practical response to a long-standing challenge: how to enable seamless, trusted, cross-border data sharing in real estate.

What is GDX?
GDX is a federated data exchange network, not a centralized database. Each participating MLS remains fully in control of its data—deciding who can access it, how it’s used, and under what agreements.
Think of it as a network of connected marketplaces, where each node (MLS) maintains authority while gaining the ability to collaborate globally.
Why the Industry Needs It
For years, the real estate industry has faced fragmentation:
- Data locked in local systems
- Limited international exposure for listings
- Missed opportunities for cross-border transactions
Meanwhile, billions of dollars in international real estate activity continue to flow—often without benefiting MLS participants directly.
GDX changes that by:
- Enabling global visibility of listings
- Supporting referral and transaction opportunities
- Ensuring listing agent attribution and data integrity
- Creating new value for brokers, agents, and MLS subscribers
How It Works
Built on RESO standards, GDX ensures that data can be shared efficiently across markets, languages, and systems.
Key principles include:
- Standardization: A common data language for global interoperability
- Control: Each MLS governs its own data relationships
- Scalability: A growing network effect as more participants join
- Trust: Verified MLS frameworks and compliance-driven participation
Who’s Involved
Early adopters include leading organizations like Stellar MLS and Miami REALTORS®, alongside emerging MLS markets across Europe, the Middle East, and beyond.
With new countries joining continuously, GDX is quickly evolving into a living global network.
What It Means for Agents and Brokers
For professionals on the ground, GDX is about opportunity:
- More exposure for listings—locally and internationally
- Access to inbound and outbound buyers
- Stronger referral networks
- New revenue streams in a shifting market
As transaction volumes fluctuate, expanding the “marketplace” becomes not just beneficial—but essential.
Looking Ahead
In the next few years, GDX is poised to become the global infrastructure for real estate data exchange—a foundation for collaboration, transparency, and growth.
It’s not just about sharing data.
It’s about unlocking the global real estate ecosystem.
And for the first time, the industry has a standard—and a system—to make it happen.
