Philadelphia Big-Box Retail Report H1 2025

The Greater Philadelphia big-box retail market held steady in the first half of 2025, with aggregate fundamentals showing minimal change. The number of available spaces declined marginally, while there was a modest half-over-half increase of less than 50,000 sq. ft. This contrasts with 2024, when a wave of retailer bankruptcies drove a notable increase in availabilities, the first rise since 2021. Despite macroeconomic headwinds and the lingering effects of major retail closures, the market demonstrated resiliency as vacancy rates remained stable, landlords actively backfilled space and new construction and redevelopment fueled growth.
