How much is Howard Marks Worth? Howard Marks Net Worth in 2026
Howard Marks’s net worth is estimated at $1.0 billion as of November 2026. He never had to sell Oaktree in a hurry: the firm he co-founded was bought in two stages, and the second stage was announced in October 2025. Marks is an American credit investor, the author of a widely read series of investor memos, and still co-chairman of Oaktree.

This one is a rough estimate: his personal ownership of Oaktree is not public. We know what Brookfield agreed to pay for the company, so the firm’s value is documented, but his share of it is our assumption. We settle on $1.0 billion with a range of $0.6 billion to $1.6 billion.
How we got to $1.0 billion
| Source | Our estimate | What it rests on |
|---|---|---|
| Oaktree interest | About $1,150 million | A trade report said in October 2025 that Brookfield would buy the remaining 26 percent of Oaktree for about $3 billion, which prices the whole firm near $11.5 billion. We assume Marks held about 10 percent of the firm over time. |
| Other investments and property | About $100 million | Our placeholder; none of it is itemised publicly. |
| Tax on cash already received | Minus $250 million | Roughly 22 percent of the Oaktree row, an assumption covering the 2019 sale and later distributions. |
| Total | About $1.0 billion | $1,150 + $100 – $250 million. |
The same firm, priced twice
In 2019 Brookfield agreed to buy 62 percent of Oaktree for roughly $4.7 billion, a price that put the whole firm at about $7.6 billion. Six years later the last 26 percent was priced at $3 billion, which implies about $11.5 billion.
Our calculation: $11.54 billion divided by $7.58 billion is 1.52, so the firm is worth about 52 percent more than at the first deal. A 10 percent holder’s stake rose from about $758 million to about $1.15 billion, a gain of roughly $396 million. Each percentage point of Oaktree is worth about $115 million.
Why the estimates disagree
Public estimates differ because the share of Oaktree he owns is not disclosed, because some count only the first sale, and because books and memos pay little next to the firm. The latest documented event is the October 2025 announcement, with closing expected in early 2026. Marks stays at Oaktree and on the Brookfield Corporation board, so any new equity or pay terms there would change our number.
