How much is Mark Walter worth in 2026?

Our estimate is $10 billion, and it is a rough one. His sports stakes are the visible part: team values are published and the Lakers have a sale price. His stakes in Guggenheim Partners and TWG Global, which are private, and the debt behind his team purchases are not disclosed, so those rows are our assumptions. A wide range is the honest answer here.

Adding up the teams and the firms

Source	Our estimate	What it rests on
Lakers sale proceeds	$8.75 billion	Our assumption: 70% of the team at the $12.5 billion sale valuation. He and Todd Boehly hold about 85% together, with Walter the majority owner; the split is not public. We also assume half of the 27% bought in 2021 was his, so 56.5 points came in 2025.
Debt behind the Lakers purchase	minus $1.9 billion	Our assumption: about a third of the roughly $5.65 billion his assumed extra 56.5 points cost at the 2025 price was borrowed. One third of $5.65 billion is $1.88 billion.
Tax on the Lakers gain	minus $350 million	Our assumption: a $1.41 billion gain on the 2025 shares (56.5% of the $2.5 billion rise), taxed at about 25%. We leave out tax on his 2021 shares because their price was not disclosed, so this row may run low.
Los Angeles Dodgers, 27%	$2.16 billion	27% of the $8 billion team value published in March 2026.
Guggenheim Partners and TWG Global	$1 billion	Our assumption for his stake in Guggenheim, which he co-founded in 1999, and his 21% of TWG Global. Neither publishes a valuation we could open.
Chelsea exit	$400 million	Our assumption for his 12.7% of the club’s parent, sold to Clearlake Capital in September 2026. No price was disclosed.
Other teams, homes and cash	$200 million	Our assumption for the Los Angeles Sparks, the PWHL teams, his part of the Billie Jean King Cup and personal property.
Total	$10 billion	$10.26 billion before rounding.

The $2.5 billion flip

He first bought into the Lakers in 2021, when he and Todd Boehly took a 27% stake. On June 18, 2025 he agreed to buy majority control at a $10 billion valuation, per his biography. When the NBA approved the deal that October, he and Boehly owned about 85% between them and Jeanie Buss kept roughly 15%, the minimum to stay governor, Front Office Sports reported.

On August 12, 2026 came the reversal: an agreement to sell to Josh Kushner and Bob Iger at a record $12.5 billion, still subject to the NBA board of governors, Al Jazeera reported, citing Reuters. The Buss family keeps its 15%, NBC Sports reported.

By our calculation the team gained $2.5 billion, or 25%, in about 14 months, roughly $180 million a month. On the 56.5 percentage points we assume he bought in 2025, that is a $1.41 billion paper gain before tax and before any financing costs.

A $100 million check for the Dodgers

In 2012 Walter led the $2.15 billion purchase of the Dodgers. His own contribution was reportedly $100 million, with $1.213 billion coming from Guggenheim-related businesses, according to his biography. He owns 27% today. The team was valued at $8 billion in March 2026, up from $5.8 billion a year earlier, NBC reported, citing CNBC, which puts his slice at $2.16 billion.

The firms behind the teams

He co-founded Guggenheim Partners in 1999 with the help of Guggenheim heir Peter Lawson-Johnson II and runs it as CEO; the firm manages more than $345 billion. In May 2024 he co-founded TWG Global, where he is CEO and co-chairman and owns 21%. Assets under management are client money, not his, which is why the Guggenheim row is small next to the firm’s size. Born in Cedar Rapids, Iowa, he also controls the Professional Women’s Hockey League’s six founding teams and has led the Los Angeles Sparks since 2014.

Why other estimates disagree

Public estimates for Walter sit billions apart because almost everything outside the teams is private. Some credit him with a large share of Guggenheim’s value; others count the Lakers at full sale value with no debt behind them. Several were also set before the Lakers sale and the Chelsea exit.

What would move the figure

NBA approval and closing of the Lakers sale, which turns a stake into cash. Any sale of a Dodgers stake at the new team value. A disclosed valuation of TWG Global would move our biggest guess more than anything else.
