He co-founded LibreMax Capital with Fred Brettschneider in 2010, where he continues to serve as Managing Founding Partner and Chief Investment Officer.
His career became part of popular culture when Michael Lewis profiled him in The Big Short: Inside the Doomsday Machine, published in 2010.
Actor Ryan Gosling portrayed a character based on Lippmann in the 2015 film adaptation of the book.

His roots in the New York metropolitan area have shaped both his personal and professional life.

He maintains a professional presence consistent with his high-profile role as a fund manager and frequent speaker at financial conferences.
Greg Lippmann Education
Lippmann earned his bachelor’s degree from the University of Pennsylvania in 1991, graduating magna cum laude. He majored in Economics and minored in English.
That academic record set him apart as he entered the finance world fresh out of college.
His undergraduate years at Penn in the late 1980s coincided with a formative era in financial markets, giving him a strong foundation in economic theory.
Greg Lippmann Career
Greg Lippmann began building his Wall Street career directly after graduating from the University of Pennsylvania in 1991. His path took him through two of the biggest names in global finance before he launched his own firm.
Career Start at Credit Suisse
Lippmann joined Credit Suisse in 1991 immediately after graduation. He worked his way up to Director and Head of ABS/MBS Subordinate and CDO trading during his nearly decade-long tenure there.
By the time he left Credit Suisse in 2000, he had developed deep expertise in structured financial products. That experience made him an attractive hire for Deutsche Bank.
Rise at Deutsche Bank
Lippmann joined Deutsche Bank in 2000 as a trader of non-investment grade ABS and RMBS securities. In 2003, he became Global Head of ABS and CDO Trading, leading a team of 30 senior professionals across New York and London.
Deutsche Bank made nearly $2 billion from Lippmann’s subprime short trade in 2007 alone.
Starting as early as 2006, Lippmann began building short positions against subprime mortgage-backed securities. He identified weaknesses in loan underwriting and housing market fundamentals that most of Wall Street ignored at the time.
He actively distributed a detailed research presentation to hedge funds, convincing at least 50 of them to take similar positions using credit default swaps.
Among those he persuaded were investors later featured in The Big Short, including FrontPoint Partners and Cornwall Capital. When the housing market collapsed in 2007 and 2008, those positions paid off enormously.
The Big Short and Public Recognition
Michael Lewis described Lippmann as a central figure in The Big Short: Inside the Doomsday Machine, published in March 2010. The book spent 28 weeks on the New York Times bestseller list.
Lippmann departed Deutsche Bank in April 2010 and his role there was succeeded by Pius Sprenger.
In the 2015 film adaptation, director Adam McKay cast Ryan Gosling to portray the Lippmann-inspired character, Jared Vennett. The film grossed over $133 million worldwide.
Co-Founding LibreMax Capital
In February 2010, Lippmann announced he would join a hedge fund alongside Fred Brettschneider, formerly Deutsche Bank’s head of global markets.
They co-founded LibreMax Partners, with Lippmann taking the role of Chief Investment Officer and Portfolio Manager.
LibreMax launched with approximately $400 million in assets under management and reached $2.3 billion in just two years.
The firm focuses on structured products, particularly residential and commercial mortgage-backed securities, and asset-backed finance.
Recent Work
LibreMax reported a 6.59% year-to-date return through the third quarter of 2025, with an annualized return of 6.67% since inception. Assets under management reached approximately $12.4 billion by late 2025.
In May 2016, Lippmann also partnered with Promise Financial on a wedding loans business.
On May 1, 2026, LibreMax launched the LibreMax Asset-Backed Income Fund (LMIFX), its first publicly registered interval fund. The fund launched with $285 million in committed capital from three institutional investors, including a large Midwest public pension, a U.S. sovereign wealth fund, and a global multi-family office.
