Nobody has ever added up what Hudson Yards cost New York

That absence is the story. Hudson Yards is the largest private development in American history and one of the most written-about, and the question of what it cost the public has no official answer — only an academic estimate, a set of press figures that are larger and unexplained, and two numbers the city publishes about itself that do not match the city’s own audited books.

It matters now rather than historically, because Related is asking for roughly $2 billion more, on the same mechanism, to build the western half.⁸

The promise was that it would pay for itself

The mechanism was tax increment financing, and the pitch was elegant. The city would issue bonds through a corporation created for the purpose, spend the proceeds on a subway extension and a park, and repay the bonds out of the new property taxes that the subway and park would call into existence. No general-fund money. The district would fund itself.¹

The subway opened in September 2015, against a plan that had budgeted $2.1 billion for it.¹ The overruns did not stay inside the structure: the city absorbed $218 million of them, plus $182 million of spillovers it had not planned for at all — a new public school and the Culture Shed — out of its own capital budget.⁶

What the pitch did not survive was the timing. The bonds were sold in 2006 and 2011; the towers that would pay for them did not open until 2016 and later. In the gap, the interest still came due, and the city paid it out of the general fund — the thing the structure was designed to avoid. Those payments are called interest support, and they are where the arithmetic starts coming apart.

The number the city cannot agree with itself about

Start with how far off the estimate was. The 2007 bond statement told investors that interest support would cost the city $7.4 million through 2015. The actual figure was $359 million — over forty times more than expected, in the study’s own words.⁶ That is not a project running slightly behind. It is a forecast that was wrong by an order of magnitude on the one number the structure’s whole promise depended on.

And $359 million is the figure every source that matters uses: the Independent Budget Office, the Comptroller’s own newsletter restating it six years later, the press, and the New School study that folds it into its total.⁶

Add up the interest-support line items in the corporation’s own audited financial statements, year by year, and you get about $188 million.⁴ Not a rounding difference — a gap of roughly $171 million between a figure the city repeats and a figure the city audits. No document anyone has found bridges the two.

The same shape appears on the way back. The Comptroller’s office has stated that HYIC transferred $863 million to the city across fiscal 2017 to 2023. Summing the payments in that office’s own published audited statements for the identical period gives about $750 million.^3,4 The gap is roughly $113 million, and it is the same size in an earlier restatement of the same figure, which suggests a real reconciling item somewhere rather than an error — but nobody has published what it is.

Neither gap means anyone is lying. Cash and accrual accounting differ; a refunding can route money through a separate entity; capitalised interest drawn from bond proceeds before a line item existed would not appear where a later reader looks for it. Any of those could explain it. The point is that none of them has been published, and that a project whose defining promise was fiscal self-sufficiency has never had its fiscal record reconciled in public.

What the borrowing bought

The public money went in first, and it went in before there was anything to tax.

What one tally actually contains

The number that has five versions

Because there is no official figure, the press supplied several, and they do not agree with each other or with the study they all cite.

The record has a stain

Four people have died by suicide at the Vessel since it opened in March 2019. The structure closed after the third death in January 2021, reopened that May with a rule against solo visitors, closed again after a fourth death in July 2021, and reopened permanently in October 2024 with floor-to-ceiling steel mesh and roughly half its stairways accessible. The chair of the local community board, after the fourth: “This was totally foreseeable and totally preventable.”

The private capital has its own record. More than a billion dollars of the equity came from the federal EB-5 programme, which offers foreign investors a visa route at a discounted threshold when they invest in areas of high unemployment. Hudson Yards qualified because New York State drew a targeted employment area that reached up through Central Park and into public-housing tracts in Harlem — stringing together non-contiguous census tracts until the average unemployment cleared the bar. Senator Chuck Grassley named the project on the Senate floor in October 2015 as “one of the most notorious examples” of that practice.¹⁰ A federal audit the following year found the pattern was national rather than unique: almost all sampled petitioners used the discounted route, and ninety per cent of those combined multiple tracts.¹¹ Related’s answer has been that it used a federal programme and followed the applicable rules, which is true and is not a defence of the rules.

And the affordable housing negotiated in 2005 as the price of Council approval has substantially not arrived. The commitment was 3,347 new affordable units district-wide, including named public sites; the largest of them was still unbuilt fourteen years later.

The same ask, on the empty half

The eastern half is finished and the western half is still a rail yard. Related wants to deck it too, and the ask is the part most coverage gets wrong: the roughly $2 billion is not a cheque. It is the same PILOT structure — a city entity issues debt to build the platform, Related pays discounted property taxes, and those discounted taxes service the debt.⁸ The City Council approved that structure in June 2025. As of the most recent reporting the final tax exemption and bond issuance were still pending, and the current administration has said it is not actively engaged in moving the project forward.⁹

The case for it is that platforms earn nothing. A tower can be financed privately because it produces rent; a deck over live tracks produces nothing at all and no private lender will fund one alone. If the city wants four thousand homes, a school and a park on that site, it has to pay for the thing underneath them first. That is a real argument and the eastern half is evidence for it.

The case against it is the one the Comptroller’s office made: that the structure is “open-ended” — “it could be anything as far as we know”.⁹ Which brings the argument back to where this study began. The east side is the precedent being cited, and the east side has never been added up.

What transfers

Tax increment financing is a real tool and it is not a scam. The bonds here are investment grade, twice upgraded, and the district’s revenue is now running ahead of the budget set for it — the Comptroller who had been its most prominent critic said in 2023 that he had got it wrong.⁷ Judged as a bond, Hudson Yards is working.

But a bond is not the question. The question is what a city gives up and what it gets, and that requires a total. Tax increment financing is unusually good at hiding one, because almost none of its cost is an appropriation. A discounted assessment is not a cheque anyone signs. An abatement does not appear in a budget. Interest support does, but only in a line most people will never read. The costs are real, they are large, and they are structurally invisible.

So the transferable lesson is not that Hudson Yards was a giveaway or that it was a triumph. It is that twenty years and roughly $5 billion of public exposure later, the honest answer to “what did it cost” is that two academics made an estimate, the press made larger ones nobody can reconstruct, and the government made none. Before backing the second half, the arithmetic on the first half is the cheapest thing anyone could ask for.

And when you are handed a number for a project like this, ask which of these it is: money spent, money foregone, or money borrowed and being repaid. Those three do not add together, and almost every published figure about Hudson Yards is what happens when they are added anyway.
