The Denver Broncos introduced in early September 2025 their plan to construct a privately financed soccer stadium. The proposal gained a large number of consideration and reward.
Around the 5 main sports activities leagues within the U.S. – the NBA, NHL, NFL, MLB and MLS – best 20% of amenities are privately owned.
I’ve studied the intersection of state and native public finance and professional sports activities for 20 years. This revel in has led me to method claims of personal financing with suspicion.
Personal bucks are regularly masked as public bucks in those preparations.

Personal vs public bucks
In concept, what counts as non-public or public bucks is uncontroversial. Bucks are public when govt has a prison declare over them – another way, they’re non-public.
The general public as opposed to non-public buck difference issues when accounting for who’s contributing how a lot to a sports activities facility. When public bucks are allowed to rely as non-public bucks, a mission proposal appears extra engaging than it’s, in truth.
For example, lawmakers ceaselessly permit workforce house owners to rely public bucks as non-public bucks. The Sacramento Town Council agreed to let the NBA’s Sacramento Kings rely their assets tax bills for the city-owned area as non-public contributions to the entire price of financing the sector. However assets taxes are public bucks that during different cases cross towards public services and products like colleges and highway upkeep.

Staff house owners development non-public amenities additionally usually obtain public bucks via tax breaks, which is govt spending in cover. Assets tax exemptions, gross sales and use tax exemptions on fabrics and equipment, and source of revenue tax credit are commonplace sorts of govt givebacks to sports activities workforce house owners.
I’ve estimated that assets tax exemptions by myself, amongst amenities within the 5 main leagues, have price state and native governments US$20 billion cumulatively over the lifetime of groups’ rentals, 42% of which might have long past to Okay-12 schooling.
Condominium bills spent on amenities don’t seem to be non-public bucks
Many amenities and their infrastructure are funded via public debt secured partially by way of workforce condominium bills. Lawmakers, media and experts regularly view tasks secured by way of rents as privately financed, partially or complete.
Then again, condominium source of revenue in change to be used or operation of public assets will have to no longer be counted as non-public bucks.
Right here’s a idea experiment. Think state lawmakers allotted the hire paid to be used of campground websites in a state park to pay for brand new campground toilets. Are the toilets privately funded?
The flaw in concluding “yes” arises from a failure to comprehend that lawmakers, via coverage, create prison claims over positive bucks. All bucks get started as non-public bucks, however throughout the tax machine, lawmakers switch possession of a few bucks to the general public.
It’s the govt landlord’s selection, a coverage determination, to spend the condominium source of revenue at the rented assets, a decision to be had to them provided that they personal the condominium source of revenue within the first position.
But lawmakers ceaselessly permit groups, each skilled and minor league, to rely condominium bills as non-public contributions. This accounting makes sports activities subsidies glance much less beneficiant than they in fact are.
Taking a look past building
Amenities no longer best wish to be built but additionally operated, maintained and ultimately upgraded. Roads, sewer strains, overpasses, game-day safety and emergency reaction and public insurance policies to mitigate gentrification brought about by way of a facility are all commonplace taxpayer-funded touchpoints. As well as, amenities have preconstruction prices equivalent to land acquisition, soil remediation and web site preparation, in addition to later prices equivalent to demolition and remediation for the land’s subsequent use.
That specialize in privately financed building and ignoring all different sides of a mission’s building and operation is deceptive, doubtlessly contributing to lawmakers making inefficient and costly coverage choices.

By the use of instance, the Council of the District of Columbia licensed a subsidy settlement remaining 12 months with the NFL’s Commanders. The stadium could be financed, built and operated by way of the workforce proprietor, who would pay $1 in hire in step with 12 months and remit no assets taxes. In change for financing the stadium privately, the landlord receives unique building rights to twenty acres of land adjoining to the stadium for the following 90 years.
The stadium is anticipated to price the landlord $2.5 billion, with town contributing $1.3 billion for infrastructure.
However the metropolis additionally offers up marketplace condominium source of revenue between $6 billion and $25 billion,relying on long term land appreciation charges, that it would make at the 20 acres.
In different phrases, the hire cut price by myself approach town offers up income equivalent to more than one stadiums in change for the Commanders offering one. It’s as though the council has a Lamborghini, traded it immediately up for a Honda Civic, after which praised themselves for his or her negotiation acumen that led to a “free” Civic.
The Broncos’ proposed stadium
As of January 2026, Denver taxpayers know best that the Broncos stadium building shall be privately financed and that public bucks shall be spent on some infrastructure.
Being enamored with any such proposal is very similar to being presented a $1 billion yacht at a 75% cut price. In my revel in, there are two kinds of public officers: one will need to spend $250 million to avoid wasting $750 million, whilst the opposite will ask whether or not $250 million for a yacht is a suitable use of taxpayer assets given current wishes somewhere else.
My hope is that lawmakers higher respect the numerous tactics govt participation in sports activities facility building, together with privately financed ones, imposes critical dangers and prices for present and long term taxpayers. What’s the anticipated overall price of the stadium mission over its existence? How a lot of the existence price would public assets duvet? May just public assets generate better advantages in another use? How a lot will it price to mitigate or compensate the ones suffering from a mission’s anticipated damaging negative effects, equivalent to gentrification, congestion, air pollution and crime?
