Jamie Dimon
Chairman and CEO at J.P. Morgan Chase
Last year's rank: 3
In October 2025, J.P. Morgan Chase officially opened its new 2.5 million-square-foot, 60-story global headquarters at 270 Park Avenue. The move by the nation’s largest bank underscored the U.S. office market’s recovery from the depths of the pandemic and the recovery of workaday New York City. The all-electric tower — the city’s largest — has room for more than 10,000 employees and a host of amenities to service them.
Two months later, J.P. Morgan would close out a year wherein it originated $87 billion in commercial real estate loans. That sum spread across asset classes, including a $38 billion construction financing package it led for a pair of hyperscale data centers. (The J.P. Morgan executives running the bank’s CRE lending, Michelle Herrick and Brian Baker, topped Commercial Observer’s 2026 Power Finance rankings.)
Meanwhile, the bank expanded its existing office and retail footprints over the past 12 months. In New York — despite that gargantuan new HQ — the company leased a further 139,332 square feet at Five Manhattan West. In San Francisco, the bank announced it would expand to nearly 280,000 square feet at 560 Mission Street. J.P. Morgan also announced that in 2026 it would open more than 160 new bank branches in more than 30 states and renovate a further 600.
At the center of it all is Jamie Dimon.
The aforementioned moves and figures are impactful enough. (As is the bank’s recent performance — net income and revenue were both up by double digits annually in the first quarter, to $16.5 billion and $50.5 billion, respectively.) But, when Dimon pronounces or prognosticates on the economy or geopolitics, the impact compounds like interest on a loan. He is probably the most listened-to financial figure in the country outside of government. He would say it’s all in a day’s work.
“We’ve always been focused on doing what’s right for clients — putting capital to work, and finding smart, innovative ways to help them succeed,” Dimon said in a statement to Commercial Observer. “We proudly support the entire commercial real estate sector, bringing the full strength and breadth of J.P. Morgan Chase to help them in any market environment.”
