Three Western MLSs launch Orion data exchange; Stellar MLS expands in Florida

# What happened Three Western multiple listing services — MetroList, Northern Nevada Regional MLS (NNRMLS) and Oregon Data Share — announced the Orion Real Estate Data Exchange on Sept. 23, 2026. The initiative creates a multi-state data-sharing arrangement that covers portions of California, Nevada and Oregon.

At the same time, Stellar MLS announced it will be the exclusive MLS provider for the West Pasco Hernando Realtors (WPHR) in Florida after the merger of two local associations, discontinuing Hernando County's single-association MLS.

# Why Orion was launched The three MLSs say the region sees meaningful consumer mobility: they cite U.S. Census Bureau estimates that about 129,000 people moved between California, Nevada and Oregon in 2024. Orion is intended to make listing information more accessible to practitioners working across those markets and to strengthen referral connections when clients relocate.

Orion's first phase emphasizes "practical access" to listing information in a professional user environment, delivered through Rapattoni-powered MLS tools. A later phase will bring data directly into each organization's primary MLS system in a structured way, which the partners say will create a more seamless experience for members.

NNRMLS CEO George Pickard framed the rollout as a staged approach: starting with usable access today while building the infrastructure for deeper data sharing down the line.

# How Orion will work (initial and next phases)

• Initial phase: Members of each participating MLS can view listing information across the Orion footprint through Rapattoni-powered interfaces. The emphasis is on making cross-market listing data available in a professional environment.

The announcement signals an open posture: other MLSs could opt in to the exchange later, expanding the geographic scope and the potential value of shared inventory.

# Stellar MLS expansion in Florida

WPHR CEO Brenda Rabbitt said the partnership responds to members' requests for advanced resources and broader market reach. Stellar MLS CEO Shayne Fairley stated the move will give both WPHR members and existing Stellar customers greater access to inventory and technology across a more connected network.

# What this means for members and brokerages

• The staged rollout reduces immediate integration complexity while signaling a roadmap toward tighter system-level data exchange.
• If other MLSs join, regional coverage and referral workflows could improve further.

• West Pasco and Hernando members will use Stellar's platform and technology, and the local single-association MLS in Hernando County will end.
• Brokerages and agents in the merged association gain the larger market access and tools that Stellar offers.

# Bottom line Orion formalizes a multi-state data-share option in the Western U.S. with a practical first phase and a planned move to structured, system-level integration. Stellar's exclusive agreement with the new WPHR represents continued MLS consolidation and platform consolidation in Florida.
