Clear Street first took space at the 72-story, Class A+ tower in Lower Manhattan via a sublease in 2021. It followed that up in 2023 with a direct lease with Silverstein for the entire 45th floor.

With this extension, Clear Street will keep its headquarters at 4 WTC and expand onto the entire 46th floor.

The deal brings 4 WTC to 97 percent leased. Other noteworthy tenants at the 2.3 million-square-foot tower include Spotify, Zurich American Insurance Co., Duolingo, SNY and Rippling.

Clear Street COO Jon Daplyn cited the building’s “innovative design, spectacular views and proximity to transit” as among its attractions.

Silverstein Properties was represented in-house by Keith Cody and Gordon Hough. Clear Street was represented by Josh Berger of Norman Bobrow & Co.

Retail tenants at 4 WTC include Eataly, Banana Republic and H&M.

Transit access at the tower includes an underground pedestrian concourse that leads directly to 12 subway lines and the PATH train.

4 WTC was designed by Pritzker Prize–winning architect Fumihiko Maki and is rated as LEED Gold.

Manhattan’s office leasing surges

Manhattan’s office leasing hit a nearly six-year record in the second quarter, with 8.4 million square feet, including six leases of more than 100,000 square feet each, according to a report from Cushman & Wakefield. Of those, New York University’s 1.1 million-square-foot commitment at 770 Broadway was the largest new lease since the fourth quarter of 2019.

Further, Cushman & Wakefield reported, renewal activity also has grown, with 4.7 million square feet year to date, nearly 50 percent higher than 12 months prior.

The World Trade submarket has an overall vacancy of 18.0 percent on an inventory of 24.1 million square feet. Net absorption year-to-date has been 592,000 square feet.

It was not quite a year ago that StubHub signed a sublease for about 100,000 square feet at 4 WTC. In an agreement negotiated by Savills, StubHub immediately took possession of one floor in the building and was to take over two more floors from the sublessor at a future date.
