The AI Boom Has Widened The Split Between Office Winners, Losers

Why It Matters

The split creates a winner‑takes‑all dynamic that reshapes capital allocation, driving premium asset premiums while forcing weaker properties toward conversion or discount sales. Understanding this shift is critical for investors, developers, and corporate occupiers navigating a market reshaped by AI and post‑pandemic work patterns.

Key Takeaways

• AI tenants signed over 1.2 M SF in NY and SF Q1
• Overall U.S. office leasing dropped 20% YoY in Q1
• Office vacancy sits at 22.2% nationally, pressuring landlords
• Heitman seeks top‑tier office towers despite market weakness
• Conversions to residential rose 28% in 2025, now 47% of projects

Pulse Analysis

The surge of generative AI is redefining office demand, concentrating leasing activity in a few elite towers while the broader market contracts. In the first quarter, AI powerhouses such as Anthropic and OpenAI added more than 780,000 square feet in San Francisco, and New York recorded 415,000 square feet of AI‑related leases—representing a sizable share of total office transactions. Yet overall leasing slipped 20% YoY, and vacancy climbed to 22.2%, underscoring a stark divide between high‑grade assets that attract tech tenants and the mass of older, less‑modern spaces left idle.

Investors are responding with a two‑pronged strategy. Global firms like Heitman, managing $47 billion, are doubling down on premium properties, betting that top‑tier locations will retain demand despite AI‑driven efficiency gains. Simultaneously, a wave of value‑add and opportunistic buyers is capitalizing on depressed prices, with office sales volume rising to $6.3 billion in Q1 and cap rates compressing to 7.26%. This activity reflects confidence that even a fragmented market can yield solid returns when buyers focus on assets with strong tenant pipelines or conversion potential.

Adaptive reuse is becoming a critical lever for stabilizing supply. Office‑to‑residential conversions jumped 28% in 2025, now accounting for 47% of all adaptive‑reuse projects, as developers strip under‑performing floors for housing units. The reduction of office inventory—down more than 2% quarter‑over‑quarter—helps keep vacancy from spiraling higher, while providing a hedge against the ongoing AI‑induced office downsizing. Together, these trends suggest a market in transition: premium AI‑centric office space will command premium rents, whereas the rest of the sector will increasingly pivot toward mixed‑use or residential uses to sustain value.
