AI research company Thinking Machines Lab has signed a 21,500-square-foot lease at 79 Fifth Avenue near Union Square, establishing its first New York City office and adding another AI tenant to Manhattan’s growing technology leasing market.
According to Commercial Observer, the company will occupy the entire fourth floor of the 18-story office building, located between East 15th and East 16th streets, one block west of Union Square.
The financial terms of the lease were not disclosed. Asking rents at 79 Fifth Avenue are slightly above $100 per square foot, according to a source cited by Commercial Observer, although asking rent should not be treated as the actual rent agreed to by Thinking Machines Lab. JLL represented the tenant, while Newmark represented landlord Kalimian Properties.
What makes this transaction particularly relevant for New York real estate is that it represents new office demand rather than a relocation from another Manhattan property. Thinking Machines Lab was founded in San Francisco in early 2025, and 79 Fifth Avenue will be its first New York office.
The lease also fits a much broader trend.
According to Colliers’ 2026 Midyear Manhattan Tech Sector Report, technology companies leased approximately 4.15 million square feet in Manhattan during the first half of 2026, up 59.5% year over year and the highest midyear total on record.
AI companies alone accounted for approximately 1.50 million square feet across 63 transactions, nearly double their leasing volume for all of 2025. Midtown South, which includes the broader Union Square and Flatiron technology ecosystem, captured 75.1% of Manhattan technology leasing activity during the period.
Thinking Machines Lab’s New York entry therefore provides a property-level example of a trend already visible in the broader market: AI-sector growth is increasingly translating into actual physical space requirements.
Why the Thinking Machines Lab NYC Office Matters for New York Real Estate
For real estate investors, the important question is not simply whether AI companies are growing. It is whether that growth creates sustainable demand for physical space.
A company establishing its first New York office creates incremental demand rather than simply shifting an existing tenant from one Manhattan building to another.
That matters because healthy office markets ultimately depend on businesses that need more space, new companies entering the market and industries capable of supporting future employment and leasing activity.
At the same time, AI-sector growth should not be treated as a guarantee for every office asset. Landlords and lenders still need to evaluate location, tenant quality, lease terms, building competitiveness and the concentration of demand within specific submarkets.
EB-5 Investor Insight
1. Market demand should have an identifiable source.
When evaluating real estate, investors should ask who will actually use the property and why. Industry growth, employment and business formation can provide a stronger foundation for demand than relying solely on projected appreciation.
2. New demand and tenant relocation are not the same.
A company entering a market for the first time adds to the overall pool of occupied space. That can provide a more meaningful demand signal than a tenant simply moving from one building to another within the same market.

ARCFE View
For ARCFE, this transaction is more meaningful than another 21,500-square-foot office lease.
It provides a concrete example of how industry growth can move from an economic trend into actual real estate demand.
New York continues to attract companies operating in AI, technology, finance, healthcare and other high-value industries. When businesses establish or expand physical operations in the city, that activity can support demand not only for offices, but also for housing, retail, restaurants and other urban services.
ARCFE was founded by iCross Capital, a New York City real estate financing institution with nearly 20 years of lending experience. That lender-side perspective shapes how ARCFE evaluates real estate-backed EB-5 projects: rather than looking at a building in isolation, we consider where demand comes from, whether the surrounding market is attracting businesses and people, and whether those fundamentals can support the underlying asset over time.
For EB-5 investors, this is an important part of location analysis. A strong real estate market is ultimately supported by cities and neighborhoods where companies, talent and capital continue to choose to locate.
