SL Green’s Multi-Pronged Approach
The Real Deal reports that Manhattan office giant SL Green is advancing on multiple fronts in early 2026, despite hurdles faced in 2025. The REIT is executing a dual-track strategy: selling $2.5B in assets and concurrently pursuing about $1B in acquisitions and new development. The newly promoted president, Harrison Sitomer, is tasked with steering these efforts across the portfolio.
Leasing Surge Boosts Confidence
Office leasing momentum has accelerated, with SL Green signing more than 900 KSF in Q1 2026. Major deals include The Carlyle Group taking 150 KSF at 245 Park Avenue, and prominent AI firms like Clay and Harvey AI committing to large blocks of space. AI companies alone accounted for more than 500 KSF of leasing in the first months of 2026, underscoring sector growth. The surge reflects a broader trend in Manhattan, where demand from fast-growing AI firms has been helping drive the city’s office recovery.

Strategic Transactions Underway
Key asset sales and acquisitions highlight the firm’s capital recycling strategy. Notable transactions include entering contract to buy Park Avenue Tower for $730M and finalizing the acquisition of 346 Madison Avenue, a site with potential for a new 800 KSF office tower. SL Green also sold a minority stake in 100 Park Avenue and is marketing other major office properties, including 1350 Sixth Avenue and 750 Third Avenue, with the latter slated for apartment conversion.
What’s Next
SL Green’s business model remains focused on rapid lease-up, capital recycling, and new Midtown office development. With leasing momentum strong and investor interest in prime office assets, the firm is positioning for redevelopment and continued leadership in the Manhattan office sector in 2026.
