Summary
Citadel founder and CEO Ken Griffin is positioning Miami as a major business capital and, by extension, his own influence on national politics. According to Fortune, Citadel's crown-jewel headquarters on Biscayne Bay, a 54-story design by Norman Foster, is slated for completion in 2030 at a cost recently estimated at $2.5 billion. Griffin credits Miami-Dade County, which designated the site as part of a rapid transit zone that expedites zoning approval, with approving the project in around 18 months, a timeline he says would have taken years in most other major metros.

Griffin's political profile is central to the article. With a net worth estimated at roughly $50 billion, he has donated almost $250 million over the past decade to candidates including Florida Gov. Ron DeSantis and Senators Tim Sheehy (R-Mont.) and Dave McCormick (R-Pa.). Fortune notes that Griffin has become one of the more critical business voices toward the second Trump administration, arguing that the tariff regime "encourages crony capitalism" and that CEOs are forced to "stomach going to D.C. and sucking up to one administration after another." He nonetheless supports some of the president's policies. His stated agenda blends conservative positions on lower taxes, free trade, fewer regulations, school choice, and pro-growth urban policy with immigration reform and an end to cronyism.

The article places Citadel's relocation in the context of Miami's broader shift. Historically an economy built on tourism, wealth management, and residential construction, Miami has attracted companies including ServiceNow, Palantir, Thoma Bravo, and Peter Thiel's Thiel Capital, as well as a growing McKinsey office and a 41-story Santander tower under construction in Brickell. Citadel's hedge fund manages $69 billion, and Citadel Securities, its market-making arm, handles roughly one in four U.S. equity transactions and generates well over $10 billion in annual net revenues, according to the article.

Citadel's Florida move began in March 2020, when Griffin rented the 207-room Four Seasons Palm Beach and relocated the firm's trading floor in five days, supporting a year of operations with 60 traders on site. Griffin was born in Daytona Beach and attended Boca Raton Community High School, where Fortune reports he was a standout in a tech-oriented community shaped by IBM engineers. Fortune's account portrays Griffin's Miami move as both a business bet and a personal homecoming.
