Both teams play in SoFi Stadium, which Rams owner Stanley Kroenke financed to the tune of more than $5 billion. Kroenke owns and operates the stadium. The Chargers, owned by the Spanos family, are just tenants.

The Rams get about 85% of the stadium’s revenue from luxury suites and sponsorships, as well as all the revenue from non-NFL events, according to a person familiar with the matter. That leaves about 15% of suite and sponsorship revenue for the Chargers — and no money from non-NFL events.

That means, for example, when pop star Taylor Swift sold out six nights at SoFi Stadium in August 2023 during her Eras Tour, the Chargers got no piece of the pie.

Of course, building your own stadium does not come without risk. SoFi Stadium cost more than $5 billion — the most of any stadium in the world — and the Rams have $3.5 billion of debt, by far the most in the NFL.

But the risk appears to have paid off.

When Kroenke bought the Rams for $750 million in 2010, the team was in St. Louis. He moved the franchise to Los Angeles for the 2016 season at a huge expense: Kroenke had to pay the league a relocation fee of $550 million and an additional $571 million settlement fee related to a lawsuit the city of St. Louis filed over the decision to bolt to California.

Still, including that combined $1.12 billion in fees, Kroenke’s investment in the Rams is up more than four-fold since he took control of the franchise. Since moving to Los Angeles, the Rams have made the playoffs five times and have been to the Super Bowl twice, capturing the Lombardi Trophy in 2021.

The Spanos family hasn’t done too badly, though. The late Alex Spanos purchased the then-San Diego Chargers in 1984 for $72 million. Similar to the Rams, the Chargers had to pay a $550 million relocation fee. Including the fee, the value of the team has increased 81-fold since August 1984. Over the same span, the S&P 500 is up 53-fold.
