Buying a Sports Team Used to Be Vanity. Now It's a Trade.

In March 2025, a Boston-born private equity executive named Bill Chisholm bought the Boston Celtics for $6.1 billion — the largest price ever paid for an American professional sports franchise. The deal beat the previous record set when Josh Harris's group paid $6.05 billion for the Washington Commanders just two years earlier.

The record lasted three months.

In June 2025, Dodgers owner Mark Walter agreed to buy a controlling stake in the Los Angeles Lakers at a $10 billion valuation. The Lakers — the same franchise the Buss family bought for $67.5 million in 1979 — had appreciated roughly 150x in inflation-adjusted terms. Annualized: about 11%, every year, for 46 years, before a single dollar of operating income.

Pro sports just had its IPO moment. The asset class is no longer trophy property for billionaires. It's a structurally inflating, supply-constrained alternative that has outperformed the S&P 500, private equity, venture capital, and prime real estate over twenty years.

And Wall Street has finally figured out how to own it.

How Sports Quietly Became the Best Alt of the Decade

The headline number is striking: franchises in the big-four North American leagues — NFL, NBA, MLB, NHL — have returned 13.2% annualized over the past twenty years, and 16.9% in the trailing year, according to data underpinning the Ross-Arctos Sports Franchise Index, the academic benchmark built at the University of Michigan with Arctos Partners.

That is better than the S&P 500. Better than most private equity benchmarks. Better than buyout funds, growth funds, real estate, or fine art. The only major asset class that has consistently beaten it is hyperscaler equity itself — Microsoft, Apple, Alphabet, Nvidia, Meta — and those companies were not for sale in 2005.

Sports franchises were. Almost nobody could buy them.

Three structural shifts changed that:

1. The leagues let institutional capital in. Until 2020, the NBA prohibited institutional ownership of any kind. That year — quietly, in the middle of a pandemic-shortened season — the league approved a list of pre-vetted private equity firms allowed to take minority stakes up to 20%. Arctos was first. Sixth Street, Dyal HomeCourt, and Blue Owl followed. MLB had opened the door a year earlier. The NHL widened it in 2021. The NFL — the holdout — finally cracked the door in August 2024, allowing select PE firms to hold up to 10% of a single team, with a maximum of 30% institutional ownership per franchise across all approved funds.

For the first time in modern sports history, you no longer needed to be a single billionaire writing a check. You could buy a piece via a fund.

2. Media rights kept ratcheting up — alone among media properties. The NBA's 11-year, $76 billion media rights deal with Disney, NBC, and Amazon Prime Video — signed in July 2024 and running through the 2035-36 season — nearly tripled the league's previous deal in annualized terms. The NFL's media package, locked in through 2033, runs to roughly $110 billion. The deals matter because they are guaranteed revenue. Once signed, they backstop franchise cash flows for a decade-plus. In a cord-cutting world where every other piece of broadcast inventory is collapsing in value, live sports is the only content advertisers still pay a premium for. That's not a cultural observation. That's an underwriting fact.

3. The buyer pool stopped being domestic. Saudi Arabia's Public Investment Fund owns Newcastle United and is building LIV Golf into a parallel professional tour. Qatar Sports Investments owns PSG. Bahrain owns McLaren and a share of F1 logistics infrastructure. Abu Dhabi owns Manchester City and a global City Football Group portfolio across six continents. The supply of franchises is fixed. The demand pool just went from a few hundred American billionaires to several thousand sovereign wealth pools, multi-strategy funds, and PE platforms with mandates to buy.

When supply is fixed and demand multiplies, you get the Celtics-Lakers print.

The PE Land Grab Already Happened

The shape of who actually owns the alpha-generating layer of this asset class is now clear, and it has very few names on it.

Arctos Partners is the largest dedicated sports PE platform, with $15 billion in assets under management and stakes in franchises across the NBA, MLB, NHL, F1, MLS, the Premier League, and Ligue 1. In late 2025, KKR announced it would acquire Arctos in a roughly $1 billion deal — the first time one of the four big alternatives platforms (Blackstone, KKR, Apollo, Carlyle) has bought a dedicated sports manager outright. KKR's move is the signal. Sports is no longer a niche allocation inside a flagship buyout fund. It is its own category.

Sixth Street holds approved minority positions across the NBA and, via a 3% slice approved in 2025, is now inside the NFL through the New England Patriots — the first PE stake the Kraft family ever sold. Sixth Street is also Chisholm's partner inside the Celtics deal. The firm is positioning itself as the franchise-level capital provider of choice: not flipping stakes, but holding them through the next media rights cycle.

RedBird Capital has gone deeper into Europe — AC Milan outright, Toulouse FC, French rugby, a stake in the YES Network, and Liverpool via the Fenway Sports Group. RedBird is the most aggressive at platform-building: not just buying teams, but buying the broadcasters, stadiums, and infrastructure around them.

Ares, Dynasty Equity, Harbinger Sports Partners, Blue Owl HomeCourt — all raised dedicated sports vehicles in the last 24 months. Most are oversubscribed.

The pattern is unambiguous: the institutional capital that took twenty years to be allowed in is now flooding in all at once, and the underlying franchises are responding the only way scarce assets respond to a wall of capital — repricing upward, fast.

The question for a non-billionaire reading this is the obvious one: how do you actually get a piece?
