- Big-box supply tightened significantly as available inventory fell from a post-pandemic high of about 7.1M SF to 4.9M SF driven by steady backfilling of vacant space
- Leasing demand remained strong from experiential users, fitness operators, grocers, and discount retailers filling former anchor boxes
- Development activity remained robust with over 500,000 SF of new big-box space delivered in 2025 and another 500,000 SF underway
- Market fundamentals shifted toward mid-sized spaces as larger boxes were subdivided or redeveloped
- Continued leasing activity, along with redevelopment and limited high-quality supply, supports a positive and stable market outlook
