Frequently asked questions

Who runs investment decisions at 400 Capital Management?

David Portnoy is the Founder and Chief Investment Officer, overseeing all investment decisions. He previously co-headed Goldman Sachs' proprietary trading desk and credit business. John Dorfman, a co-founder and partner, also plays a key role in the firm's investment process (per public record).

What investment strategies does 400 Capital Management focus on?

The firm focuses on credit-oriented strategies, including structured credit, distressed debt, and special situations. It invests across public and private credit markets, often targeting mispriced assets during periods of market dislocation (per public record).

Is 400 Capital Management a single family office or a hedge fund?

The firm operates as a hedge fund, not a family office. It manages capital from institutional and accredited investors, not a single family's wealth. Its multi-office structure—Menlo Park, Abu Dhabi, Chicago, Boston—supports a global credit investment platform.

Does 400 Capital Management invest in fund commitments or direct deals?

The firm primarily makes direct investments in credit securities and instruments, rather than committing capital to external funds. It sources opportunities through proprietary relationships with banks, broker-dealers, and restructuring advisors (per public record).

Where does the underlying wealth for 400 Capital Management come from?

The source of the firm's capital base is not publicly disclosed. It manages external investor capital and does not appear to be a family office managing a single fortune. The Abu Dhabi office suggests a connection to Middle Eastern institutional capital.

What is 400 Capital Management's total assets under management?

400 Capital Management does not publicly disclose its AUM. Media references and industry estimates place the firm in the multi-billion dollar range, with Altss estimating $1B–$5B (Altss estimate).

How does 400 Capital Management differentiate from other credit hedge funds?

The firm's founder, David Portnoy, was an early architect of Goldman Sachs' proprietary credit trading desk, giving the firm deep structural expertise in credit markets. This background allows 400 Capital to operate across multiple credit sub-asset classes and capitalize on dislocations that more narrowly focused firms may miss (per public record).
