Guggenheim Partners is a global investment and advisory firm based in Chicago and New York. The company manages more than $350 billion in assets as of September 30, 2025. It operates through Guggenheim Investments and Guggenheim Securities with more than 2,200 professionals.
The company was founded in 1999 by Peter Lawson-Johnston II with $30 million of family money. Lawson-Johnston is the great-grandson of Solomon Guggenheim, an American industrialist.
The firm was created to bring the Guggenheim name back to Wall Street after decades away from finance. It started as a boutique financial company modeled after the classic partnerships of the past. The company’s heritage, however, stretches back more than a century.
Guggenheim Partners traces its origins to 1881 when Meyer Guggenheim invested $5,000 in Colorado lead and silver mines. The family business expanded quickly and controlled more than 80 percent of the world’s silver, copper, and lead by World War I.
M. Guggenheim’s Sons was established in 1882 by Meyer and his seven sons. It then became Guggenheim Brothers. The family enterprise introduced mining industry reforms in 1912, including pension plans and employee healthcare.
The Guggenheim business interests expanded into aerospace, media, and art over the following decades. Family member Daniel Guggenheim also funded Robert Goddard’s rocket research in 1929, which eventually led to modern rocketry.
As of 2025, Guggenheim Partners has grown from its boutique roots into a global investment banking and advisory firm with more than $350 billion AUM. The company also offers specialized services in real estate, healthcare, and institutional finance.
Guggenheim Partners delivers investment management and banking services through two main businesses and three additional units:
The firm serves governments, institutions, and individuals with complex financial needs. Guggenheim Partners focuses on long-term results and helping clients reach their financial goals.
The firm states that inclusive and equitable practices align with its guiding principles. Guggenheim Partners aims to deliver results while fostering a diverse, performance-driven culture. According to the company, its culture is built on six core values:
Guggenheim Partners states it focuses on solving complex problems creatively. The firm expects staff to uphold high standards and take personal accountability. It offers the following workplace benefits to support its people:
The company also links its diversity and inclusion strategy directly to business performance. It supports veterans through GIVE, or Guggenheim Invests in Veterans Everyday.
Mark Walter leads as Guggenheim Partners’ CEO and heads TWG Global, an international conglomerate. Walter has made headlines for sports deals, including the $10 billion purchase of the Los Angeles Lakers. He studied business at Creighton University and law at Northwestern University.
Guggenheim Partners’ executive leadership team includes the following:
The leadership team guides the firm’s strategic direction and runs its businesses. They also set the tone for Guggenheim Partners’ company culture.
Guggenheim Partners made headlines when CEO Mark Walter acquired the NBA’s LA Lakers, one of the largest sports deals in history. Although sports didn’t rank among the top three private-market opportunities in 2024–25, it still draws interest from roughly 17 percent of asset managers. This positions Guggenheim to benefit as more advisors and institutions look to sports as part of their alternative investment strategies.
Guggenheim’s Mark Walter also has a stake in the booming annuities market. Walter owns annuity providers Delaware Life and Gainbridge through his insurance holding company Group 1001. With US annuity sales nearly doubling from $219 billion in 2020 to $434 billion in 2024, Guggenheim’s leadership stands to benefit from continued growth in retirement products.
