Ground Zero's last tower: American Express and the price of finishing a 25-year rebuild

On the 25th anniversary, the memorial's first chief executive could claim what few planners once dared: Lower Manhattan is finally rebuilt. Joe Daniels took over the World Trade Center Memorial Foundation in 2004, at 33, charged with building a memorial to the 2,977 people murdered there. The surrounding district has since changed more than any other part of New York. By the state comptroller's count, the population around the site more than doubled between 2001 and 2024, from 32,446 residents to 70,761, as a one-industry business district turned into a 24-hour neighbourhood. Yet the milestone that matters to an investor arrived quietly this year, when American Express agreed to build and own the last unbuilt tower of the original post-9/11 master plan. It is a useful moment to ask who, across a quarter-century, actually carried the cost of that rebuilding — and who carries it now.

A ledger written in insurance and taxes

The price of the rebirth was never paid by a single hand. Larry Silverstein had signed a 99-year lease on the complex only weeks before the attacks, which made the destroyed asset his loss. Then a jury decided the hijacking counted as two insurance events rather than one, roughly doubling his claim; by 2007 he had collected about $4.55bn in insurance money. Most of the rest came from public sources — tens of billions of federal dollars, tax-exempt Liberty Bonds, the Port Authority's own balance sheet. The result is a campus with split ownership: One World Trade Center stands as a quasi-public building, developed by the Port Authority with a minority partner; the other towers belong to a private developer. A catastrophe therefore redistributed a large share of New York's office risk onto insurers and the public purse. That is one reason it was ever built.

The tower that waited

The exception was 2 World Trade Center. For two decades it sat as a hole and a mock-up, not for want of ambition — Foster + Partners, then BIG, then Foster again — but because a tower of that size is only constructed when someone first moves in. The economics are simple: building a 55-storey trophy costs billions before the first rent arrives, so a developer will not break ground until an anchor tenant signs what is, in effect, a blank cheque to fund it. No such tenant appeared, and the last parcel of the master plan remained a painful reminder that the rebirth was unfinished.

Whose balance sheet finishes it

Then American Express volunteered. In February 2026 the card company agreed to build and become the sole owner and occupant of 2 World Trade Center, a 55-storey tower of nearly two million square feet designed for up to 10,000 staff, on Port Authority land under a long-term ground lease, with a target move-in of 2031. The bill was not disclosed, but the company says the project will not have a material effect on its financial results — a claim easier to believe from a firm earning roughly $4.5 a share a quarter on about $19.6bn of quarterly revenue than from almost anyone else. The deal completes the last tower of the 2003 plan and follows a wider shift: corporate America increasingly owns, rather than rents, its headquarters, most visibly JPMorgan Chase, which last year moved into a newly built tower at 270 Park Avenue.

Read commercially, the wager is a bet on the flight to quality in a market that has recovered unevenly. Lower Manhattan leasing roared back in 2025 to its strongest year since 2019, but downtown still carries the widest vacancy: availability stands at 16.8%, and Class A asking rents of about $62 per square foot run a quarter below the Manhattan-wide average nearer $78. American Express is therefore buying a top-flight asset at a discount to the Manhattan-wide average while absorbing the construction and take-up risk that a landlord and its lenders would otherwise bear. To be sure, owning beats renting only if the building appreciates and the capital is cheap; here the shareholders are counterparties to a five-year build with an undisclosed bill in a district whose rents have not fully caught up. AInvest's aggregate signal for the stock is a cautious Hold, its composite reading well below the scores it gives the company's fundamentals and liquidity.

The deepest point is about who carries the risk when the celebrating stops. Twenty-five years ago the question was whether Lower Manhattan could support anything again; the answer — that it now houses more residents than it did before 2001 — carried the rebuild. The final tower will be finished not by a developer, an insurer or a government, but on the balance sheet of a credit-card company. Investors may read that as confidence in the district's recovery, or as a reminder that when a trophy skyline is complete, the office risk that once sat with landlords has simply found a new owner. This time it is American Express, and its shareholders.
