What It Costs to Buy Into a League: Every Expansion Fee in Major North American Sports
Published on August 10th, 2026Written By: Dave Manuel
In January 1966 a group of Chicago businessmen paid $1.25 million for the right to put a basketball team on the floor. Adjusted for sixty years of inflation, that is roughly $12.5 million today - less than a single season's wages for a fringe NBA starter. This year, the same league is reviewing bids for two new franchises at a projected $7 billion to $10 billion apiece. That is the arc this file measures: what it has cost, decade by decade, to buy a seat at the table in each of the major North American leagues, what those figures look like once inflation is stripped out, which league charges the most, and which one's price has climbed fastest. The short answers are that the largest fee ever actually paid belongs to the Houston Texans at $700 million in 1999, that the NBA is about to obliterate it, and that the fastest riser of all is a league most of this article was not commissioned to cover.

An expansion fee is the strangest transaction in sport. It buys no players, no stadium and no guarantee of success - only the right to exist inside a closed system, and a share of everything that system earns from then on. It is also the one number in sports finance that is almost never adjusted for inflation when it gets quoted, which makes six decades of them look far more dramatic than they sometimes are. So every entry below is written twice: once as the cheque was actually made out, and once in 2026 money. Some of these fees grew enormously in real terms. One of them barely moved. And the largest number in the file has not been paid yet.
01
National Basketball AssociationJANUARY 1966
PAYChicago Bulls expansion fee$1,250,000
One million two hundred and fifty thousand --------MEMO: FRANCHISE NO. 10Dick Klein
In 2026 money: about $12.5 million. The whole team cost less than a modern minimum-salary NBA contract pays across ten seasons.Start at the beginning, because the beginning is genuinely difficult to believe. The Chicago Bulls entered the NBA in 1966 for a fee of $1.25 million, assembled by Dick Klein - a former professional player who spent two years persuading Chicago millionaires to back him, and who remains the only person to have founded an NBA franchise after playing in the league. Adjusted for six decades of inflation that is roughly $12.5 million in today's money - less than the going rate for a decent backup point guard. The following year the NHL doubled in size in a single stroke, charging each of six new owners $2 million, or about $19.5 million today. Los Angeles, Minnesota, Philadelphia, Pittsburgh, St. Louis and Oakland all paid the same price, and it bought a permanent stake in a league that now values its cheapest club above two billion dollars. Every number in this file is measured against these two cheques, and every one of them is larger.
02
National Basketball Association1980
PAYDallas Mavericks expansion fee$12,000,000
Twelve million and no cents --------------MEMO: FRANCHISE NO. 23Donald Carter
Roughly $46 million today. The Mavericks sold in 2023 at a valuation of $3.5 billion.The Mavericks cost $12 million in 1980, which was then a startling figure and is now the sort of money a mid-table club spends on a single player. It is a useful marker because it sits almost exactly halfway between the founding cheques and the modern era, and because the return on it is documented: the franchise changed hands in 2023 at a valuation of $3.5 billion. Even after adjusting the entry fee to something near $46 million in current terms, that is a return most asset classes cannot approach. The people who wrote these cheques were not, at the time, universally regarded as making shrewd investments.
03
Major League Baseball1993
PAYFlorida Marlins expansion fee$95,000,000
Ninety-five million and no cents ----MEMO: COLORADO PAID THE SAMEH. Wayne Huizenga
About $214 million each in 2026 dollars.Colorado and Miami each paid $95 million to join the National League in 1993, worth roughly $214 million apiece today, and in both cases the money was distributed among the existing clubs rather than kept by the league. The Miami cheque was written by Wayne Huizenga, the Blockbuster and Waste Management founder, who in the same year also became founding owner of the NHL's Florida Panthers - two expansion franchises in two leagues in a single year. Colorado's bid was led by a group of local investors including Jerry McMorris. Five years later Arizona and Tampa Bay paid $130 million each, or about $259 million in current money - a rise in nominal terms and a rise in real terms too, though a modest one. What makes baseball the outlier in this file is what happened next, which is nothing. The sport has not added a team since 1998. Commissioner Rob Manfred has floated a figure in the region of $2.2 billion for any future franchise, while repeating that no expansion will be considered until the Athletics and the Rays have permanent ballparks. Baseball has the longest gap of any league here and the least clarity about when it ends.
04
National Football LeagueMAY 1993
PAYJacksonville expansion franchise$140,000,000
One hundred and forty million -------MEMO: PAYABLE WITH INTEREST OVER SIX YEARSWayne Weaver
About $315 million today. New clubs also received only a half share of national television money for three seasons.The NFL set its 1993 entry fee at $140 million and structured it in a way no other league in this file matched: the money was payable with interest across six years, and the incoming Jaguars and Panthers - bought by Wayne Weaver and Jerry Richardson respectively - received only a half share of national television revenue for their first three seasons, moving to a full share in year four. That deferred structure is the reason published figures for the Jacksonville franchise vary - the headline league fee was $140 million, while accounts of Wayne Weaver's total outlay run considerably higher once the financing and associated costs are counted. It is the earliest example in this file of a league recognising that the fee itself is only part of the price of admission.
05
National Football LeagueOCTOBER 1999
PAYHouston expansion franchise$700,000,000
Seven hundred million and no cents --------MEMO: BEGAN PLAY 2002Robert C. McNair
About $1.37 billion in 2026 money. No league has charged more for an expansion team since - because none of them has expanded.This is the answer to the most direct version of the question. The largest expansion fee ever actually paid in North American sport is the $700 million Bob McNair handed over for the Houston Texans in October 1999, a franchise that began play in 2002. In today's money that is about $1.37 billion. Twenty-seven years later it has not been beaten, and the reason is simple: the NFL has not expanded since. Every larger number discussed anywhere in this file is a projection rather than a transaction. The Texans are currently valued at around $7.4 billion, which is roughly five times the inflation-adjusted price of entry.
06
National Basketball Association2004
PAYCharlotte expansion franchise$300,000,000
Three hundred million and no cents --------MEMO: FRANCHISE NO. 30Robert L. Johnson
About $516 million today. The next NBA franchise is projected at fifteen times that, in real terms.Robert Johnson paid $300 million for the Charlotte Bobcats in 2004, becoming the first black majority owner of a major North American sports franchise. In current money that is about $516 million. What follows is the longest drought in this file: the NBA did not add another team for twenty-two years, in part because a bloc of owners resisted diluting their equity from a thirtieth of the league to a thirty-second. The arithmetic that finally changed their minds is straightforward, and it is the subject of the last entry here.
07
Major League Soccer2007
PAYToronto FC expansion fee$10,000,000
Ten million and no cents --------------MEMO: FRANCHISE NO. 13Larry Tanenbaum
About $15.7 million today. Sixteen years later the same league charged fifty times as much.Ten million dollars, in 2007, for a Major League Soccer franchise in Toronto. That is about $15.7 million in current money, and it is the single best-value cheque in this entire file. MLS operates as a single entity, which means expansion fees are distributed among the existing owners rather than retained by a league office - so every new club makes the incumbents money directly, and the incentive to keep expanding is structural rather than sentimental. It is also why the fee has risen the way it has. What Toronto paid in 2007 would not now cover a fortnight of the league's highest salary.
08
National Hockey LeagueJUNE 2016
PAYVegas Golden Knights expansion fee$500,000,000
Five hundred million and no cents --------MEMO: FRANCHISE NO. 31Bill Foley
About $677 million today. Seattle paid $650 million two years later, worth roughly $841 million now.The NHL charged Bill Foley $500 million for Vegas in June 2016, then $650 million for Seattle in December 2018, from a group led by David Bonderman and Jerry Bruckheimer - a thirty per cent rise inside thirty months, and a rise in real terms too. Both franchises have since made the fees look conservative. Vegas won a Stanley Cup in its sixth season, and the average NHL club is now worth about $1.79 billion, up ninety-two per cent since 2021. The league has told its owners that the next expansion fee will start at $2 billion, with a further commitment of at least $500 million toward an arena where a city needs one. Six potential groups have been discussed. No formal process exists, and Gary Bettman's stated position is that if somebody knocks, the league will peek around the door.
09
Major League Soccer2023
PAYSan Diego FC expansion fee$500,000,000
Five hundred million and no cents --------MEMO: FRANCHISE NO. 30Sir Mohamed Mansour
Fifty times the Toronto fee in nominal terms, and about thirty-four times in real terms, across sixteen years.San Diego became the thirtieth MLS club in 2023 at a fee of $500 million. Set that against Toronto's $10 million in 2007 and you have the steepest sustained climb anywhere in this file: fifty times the money in sixteen years, and still around thirty-four times after adjusting for inflation. No other league has moved at that rate over a comparable period. The intermediate steps show how relentless it was - $110 million for Los Angeles FC, reportedly paid with a single cheque, then $325 million for Charlotte in 2019, paid by David Tepper, then half a billion from the British-Egyptian billionaire Sir Mohamed Mansour, in partnership with the Sycuan Band of the Kumeyaay Nation, the first Native American tribe to take an ownership stake in American professional soccer. The total investment behind the club has been reported above $700 million once the academy and related costs are counted. A league that came close to folding in the early 2000s now charges more to join than the NHL did eight years ago.

Women's National Basketball Association2025
PAYCleveland expansion franchise$250,000,000
Two hundred and fifty million -------MEMO: DETROIT AND PHILADELPHIA PAID THE SAMEDan Gilbert
The Golden State Valkyries paid $50 million to enter in 2025. The fee quintupled inside roughly two years.The steepest percentage rise in professional sport right now is not in any of the five leagues this article was commissioned to cover. The Golden State Valkyries agreed a $50 million fee to begin play in 2025. Toronto paid the same, Portland $75 million, and then Cleveland, Detroit and Philadelphia each agreed $250 million - a record for any women's sports league anywhere, comfortably ahead of the $110 million a Denver group paid to join the NWSL. Every one of them was bought by an existing NBA owner: Dan Gilbert of the Cavaliers in Cleveland, Tom Gores of the Pistons in Detroit, and Josh Harris of the 76ers in Philadelphia, with the three clubs arriving in staggered fashion in 2028, 2029 and 2030 respectively. That is a fivefold increase in roughly two years, achieved without the inflation adjustment doing any work at all. Whatever else the numbers in this file show, they show that expansion pricing tracks expectations rather than history, and expectations for women's basketball moved faster than anyone's model.

National Basketball AssociationTARGETED 2028-29
PAYSeattle and Las Vegas expansion franchises$7B - $10B
Seven to ten billion -- per team ------------MEMO: BIDS UNDER REVIEWawaiting signature
Unsigned. The Board of Governors voted 30-0 in March 2026 to explore bids; a formal decision is expected before the end of this year.On March 25, 2026, all thirty NBA owners voted to formally explore expansion into Seattle and Las Vegas, with bids expected between $7 billion and $10 billion per franchise and insiders suggesting the floor is nearer $8 billion. Nothing has been signed. If it lands as projected it will be the most financially consequential expansion in the history of sport - roughly $16 billion, divided thirty ways, producing a one-off payment of around $533 million per existing owner. Crucially, expansion fees sit outside the league's revenue-sharing arrangements, so none of that money is shared with players. That single fact explains the whole file. An expansion fee is not a price a league charges. It is a payment the current owners make to themselves for agreeing to let somebody else in.

The Arithmetic
Nominal rise against real rise, first fee to next
Measured from each league's earliest fee in this file to its next known or projected one. The NFL is absent because it has not expanded since 1999, which is itself the answer to why its fee still holds the record.
What the record actually costs, in 2026 dollars
Converted to a common currency of 2026 dollars, the historic fees compress and the projected one does not. Everything before 2020 fits comfortably inside the first fifth of the chart.
The Record Book
Who Actually Banks ItThe detail that explains why expansion keeps happening: the fee does not go to the league office, it goes to the owners who are already there, divided equally. At the NBA's projected numbers that is a one-time payment of roughly $533 million per club, and because expansion fees sit outside revenue sharing, none of it reaches the players. In MLS the mechanism is even more direct - the league operates as a single entity, so admitting a new club literally adds a shareholder and pays the existing ones. Expansion is not a cost of growth. It is a dividend.
The League That StoppedThe NFL still holds the record for the largest expansion fee ever paid, and it has held it since 1999, for the straightforward reason that it has not sold a franchise since. Thirty-two teams, no additions in twenty-seven years, and no formal process to add any. It is the only league in this file whose fee has not moved at all, and the effect is peculiar: the most valuable sports league in the world charges, on paper, less than the NHL now says it wants. The number is frozen because the door is shut.
Half a Billion for a Sixth SeasonBill Foley's $500 million for Las Vegas in 2016 was widely described as steep for an unproven market. The Golden Knights reached a Stanley Cup Final in their first season and won one in their sixth, and the average NHL franchise has since risen ninety-two per cent in value since 2021. The league now says the next fee starts at $2 billion plus an arena commitment. Foley's cheque, adjusted to today's money, was about $677 million - roughly a third of what the same seat is about to cost.
The Cities That Keep PayingLas Vegas is the clearest illustration of how quickly a market can be revalued. It had no major league team at all until the Golden Knights arrived in 2017. It then added the WNBA's Aces in 2018, the NFL's Raiders in 2020, has the Athletics arriving for 2028, and is now one of two cities bidding at $7 billion or more for an NBA franchise. Seattle, meanwhile, is bidding to buy back a team it already had and lost in 2008 - at something like fifty times what the Sonics were worth when they left.
Sports-King's Note
Now for the fine printInflation adjustments are the author's own, calculated using the US consumer price index and expressed in 2026 dollars, and they are approximations - CPI is a blunt instrument for measuring the value of an asset that appreciates far faster than consumer goods, and a fee that rose ten times in real terms may still have been a poor investment or a spectacular one depending entirely on what the franchise did afterwards. Canadian and American dollar figures are not distinguished, since expansion fees in these leagues are quoted and paid in US dollars. Fees are stated as the headline entry fee announced by each league, which is not always the total cost of entry: the NFL's 1993 fee of $140 million was payable with interest across six years and came with a reduced share of national television revenue for three seasons, and published accounts of what the Jacksonville ownership group ultimately paid run higher than the league figure as a result. The MLS fee for San Diego is reported at $500 million and, like several MLS fees, is understood to be payable over time rather than in a single sum, which reduces its present value relative to a cash payment. Projected figures are exactly that: the NHL's $2 billion floor comes from commissioner Gary Bettman's remarks to his board of governors as relayed publicly by an owner, MLB's $2.2 billion is Rob Manfred's own stated range with the explicit condition that no expansion will occur before the Athletics and Rays have permanent ballparks, and the NBA's $7 billion to $10 billion is a reported bid range following a March 2026 vote to explore expansion, with no franchise awarded and no money paid. Where a league has not expanded recently, its fee is frozen rather than falling. One figure carries a genuine conflict in the sources: the Chicago Bulls fee is commonly recorded as $1.25 million, but Dick Klein told the Chicago Tribune in 1966 that the price for a 1966-67 franchise was likely to be $1.6 million, a rise he said cost him three prospective investors. The lower figure is the one that appears in expansion records and is used here, with the higher one noted.
One Last Word
The most revealing thing about these cheques is who they are written to. Not to a league, not to a sport, and certainly not to the people who play it - but to the thirty or thirty-two men and women who already own a piece, as the price of agreeing to make their own slice slightly smaller. Sixty years ago that price was one and a quarter million dollars and the buyers were regarded as slightly eccentric. This year it is heading for eight billion, and the only real question left is which cities can find someone willing to sign.
The hard numbers, for the road: the largest expansion fee ever actually paid in North American sport is the $700 million Bob McNair paid for the Houston Texans in 1999, about $1.37 billion in today's money, and it has stood for twenty-seven years because the NFL has not expanded since. The NBA charged $1.25 million for the Chicago Bulls in 1966, roughly $12.5 million now, and is reviewing bids of $7 billion to $10 billion for Seattle and Las Vegas after a unanimous vote in March 2026 - a rise of 6,400 times in cash and about 638 times after inflation. The NHL's 1967 expansion six paid $2 million each, worth around $19.5 million today, against a stated next-round floor of $2 billion. Baseball charged $95 million in 1993 and $130 million in 1998 and has not expanded since, with Rob Manfred floating $2.2 billion. MLS has climbed fastest of the five, from $10 million for Toronto in 2007 to $500 million for San Diego in 2023 - thirty-four times in real terms in sixteen years. And the steepest rise of all belongs to the WNBA, from $50 million to a record $250 million in about two years.
