Anthropic Finalizes Hudson Square Lease as it Grows in NYC

Anthropic is fully invested in Manhattan’s artificial intelligence office boom, sealing the deal for a full building in Hudson Square.

The AI firm is leasing the 16-story building at 330 Hudson Street from AEW Capital Management, the New York Times reported. Details about the lease, including asking rent and broker involvement, were not disclosed.

It was reported back in April that the company behind Claude was closing in on a deal to lease the 466,000-square-foot building. Anthropic’s existing space in New York City is limited to 15,000 square feet at 155 Sixth Avenue; signed two years ago, that lease is slated to expire this year.

There are other tenants in place at 330 Hudson Street, including Deloitte, the Financial Times and marketing agency Anomaly, all of whom will need to vacate before Anthropic moves in, according to Crain’s. That could slow the relocation process down.

The move is expected to begin over the summer. In addition to the lease, Anthropic announced plans to double its New York City workforce to 1,000 people by the end of the year; the office space is big enough to accommodate 1,700 workers.

Artificial intelligence has been one of the biggest drivers of New York City’s office market as AI companies are taking space at roughly twice last year’s pace, according to JLL data released earlier in the year.

AI tenants accounted for more than a third of the tech sector’s demand in the first quarter of 2026 with 670,000 square feet leased, according to Colliers, a sharp jump from its 12 percent share in 2025.

San Francisco remains the center of gravity for AI ascendance by number of firms and capital invested — Anthropic leases approximately 1 million square feet in the city’s downtown neighborhood — but New York City has emerged in second place among central markets for the industry.
