AI companies played a significant role in New York City’s office leasing activity in October, with two firms making the list of the largest leases for the month. However, neither secured the top position.
BlackRock expanded its presence at Hudson Yards through a new sublease agreement with Meta. Both parties were represented by a JLL team that included Peter Riguardi and Matthew Astrachan.
Stripe increased its footprint in a Financial District building by signing a new direct lease, supplementing an existing sublease. This move brings Stripe’s total space in the building to 286,000 square feet. The tenant was represented by Jeff Fischer and Sacha Zarba of CBRE, while landlord Fosun International was represented by Peter Riguardi and John Wheeler of JLL.
Swiss luxury retailer Richemont expanded within its Plaza District location, where it has maintained offices since 2001.
One AI company signed a new lease in the Flatiron District and continues to hold another lease at 315 Park Avenue South. Joseph Messina and Todd Stracci of JLL represented this tenant; Paul Glickman, Alexander Chudnoff, and Ben Bass of JLL acted for landlord SL Green Realty.
Another AI firm entered into a new sublease in the Financial District. Eddie Sisca and David Opper of CBRE represented the tenant; Scott Bogetti and Will Joumas of Savills, along with David Hollander of CBRE, represented landlord Wunderkind.
