Why It’s Moving

Housing Market Data Highlights Inventory Pressure and Price Resilience for CoStar Group
- The national median sale price reached $395,000 in August 2026, marking a 2.1% increase compared to the same period in 2025.
- Home sales volume declined by 4.3% year-over-year, indicating reduced transactional activity across the residential sector.
- The number of homes listed for sale increased by 5.4% year-over-year, suggesting that rising inventory is meeting more cautious buyer demand.

- Vodafone’s 50% OXG partner, Patrick Drahi, sold his stake to Société Générale, but the buyer reportedly will not assume deferred payment commitments; that could deprive Vodafone of as much as €1.1 billion in potential future earnings.
- The ADR opened sharply lower on September 18, extending pressure that began after the OXG disclosure and showing investors are treating the lost earnout opportunity as a material setback to Vodafone’s German broadband ambitions.
- VodafoneThree activated a new Ericsson cloud-native 5G core in the UK, a long-term capacity and reliability upgrade that supports network slicing and faster 5G services but does not immediately offset the OXG-related earnings concern.
