Ken Griffin and Kathy Warden at Semafor World Economy: What They Said and Why It Matters

Two names keep turning up in coverage of Semafor’s Washington, D.C. CEO gathering. Ken Griffin, the founder and CEO of Citadel, helps lead it. Kathy Warden, the chair, CEO and president of Northrop Grumman, has been a headline speaker. Ken Griffin and Kathy Warden Together they show what the event is for: getting finance, defense, technology and government into the same rooms while policy is still being shaped.
Below is who each of them is, what they said in 2025, how the event has changed since, and what you can and can’t verify about Warden’s personal life.
What is the Semafor World Economy Summit?
It is an invitation-based convening of global CEOs, investors and government officials, held each spring in Washington, D.C. by the media company Semafor.
The 2025 edition ran April 23–25, 2025, over three days in Washington, D.C. Its stated aim was to advance conversations that support growth and resilience in an uncertain global economy. Semafor’s own reporters run the conversations, and the event is built around a live journalism format, with a public mainstage program alongside private convenings for executives. semafor
The 2025 summit was billed as bringing together more than 200 of the world’s top chief executives. That is why it was widely described as the largest CEO gathering in America. third-news
What is Ken Griffin’s role?
Ken Griffin is a co-chair of the summit and of its advisory board.
Semafor’s site lists Ken Griffin, Founder & CEO of Citadel, as a co-chair of the 2025 summit. For 2026 the leadership group grew. The co-chairs are Kenneth C. Griffin, Henry R. Kravis of KKR, former Commerce Secretary Penny S. Pritzker and David M. Rubenstein of The Carlyle Group. semaforsemafor
Griffin’s position matters for two reasons. He runs one of the most influential firms in global markets, and he has a record of speaking bluntly about economic policy. That makes the co-chair role more than ceremonial. It signals what kind of conversations the summit wants to host.
What did Griffin say in 2025?
Griffin’s headline moment came during the tariff debate. Semafor reported that he warned that recent U.S. economic policymaking risked eroding what he considers the best national brand in the world. He also suggested the damage could take a very long time to repair. semafor
The remark drew attention because Griffin is a well-known Republican donor and was not an obvious critic of the administration. Semafor’s newsletter noted that his concerns were echoed by many people it spoke with, though executives were voicing them cautiously. That contrast, a supporter speaking candidly in public, is the kind of moment a private-sector forum with reporters in the room can produce. semafor

Who is Kathy Warden?
Kathy Warden is the chair, CEO and president of Northrop Grumman, one of the largest U.S. defense and aerospace companies.
According to the company’s profile, she was elected chairman in 2019 and has served as CEO and president since January 1, 2019. She joined Northrop Grumman in 2008 after leadership roles at General Dynamics, Veridian and General Electric. She holds a bachelor’s degree from James Madison University and an MBA from George Washington University. nasa
She has deep operational experience. Before becoming CEO she served as president and COO, and led the integration of the Orbital ATK acquisition. Her board and industry roles have included Merck & Co., Catalyst and the Aerospace Industries Association. gwu
What did Warden say at the 2025 summit?
Warden appeared on day two, in a lineup Semafor framed around fostering global innovation. Two points from Semafor’s coverage stand out:
- Defense spending: She said the U.S. needs to spend more because the national security environment is becoming more challenging. She pointed to China narrowing the gap with American superiority and noted bipartisan support in Congress for higher spending.
- Tariffs: She said Northrop Grumman, like other companies, was assessing how tariffs affect its operating costs.
Note the contrast. Griffin spoke about the broad economic and reputational risk of trade policy. Warden spoke as the head of a company whose main customer is the government, where budgets and supply chains drive decisions.
Why do these two speakers matter together?
Because they represent different halves of the same argument.
Finance and defense are both exposed to trade policy, geopolitics and government spending, but they feel it differently. One useful way to read the pairing:
| Ken Griffin | Kathy Warden | |
|---|---|---|
| Organization | Citadel | Northrop Grumman |
| Sector | Investing and market-making | Aerospace and defense |
| Summit role | Co-chair | Featured speaker (2025) |
| 2025 focus | Tariffs and the U.S. “brand” | Defense spending, innovation, tariff costs |
| Core exposure | Market confidence | Government budgets and supply chains |
This is my own analysis, not an official framing. Hearing both in one event gives attendees a fuller picture of how policy choices ripple through markets and industry at the same time.
How has the event grown since 2025?
The 2026 edition is roughly double the size and now runs five days.
Semafor announced that the flagship event, the largest CEO gathering in North America, would double in size to 400 CEOs. The 2026 dates were April 13–17 in Washington, D.C. A later announcement raised the figure, saying more than 450 top global CEOs would take part. The speakers named in that announcement included White House NEC Director Kevin Hassett, Deutsche Bank CEO Christian Sewing and Honeywell CEO Vimal Kapur. semaforbenningtonbanner
Both leaders were on the early 2026 speaker slate. Semafor’s February 2026 announcement listed Ken Griffin of Citadel and Kathy Warden of Northrop Grumman among its first confirmed names. I could confirm the announcement, but I did not find detailed coverage of what either said in 2026, so I have not summarized remarks I cannot verify. semafor
Semafor also now positions the event as a year-round platform, with an advisory board and a companion emerging-markets convening called The Next Three Billion, held around the UN General Assembly.
What topics does the summit cover?
The programming is built around a few recurring themes:
- Global economic trends and policy innovation
- The future of trade and tariffs
- The technology revolution, including AI
- Global energy
- Defense and national security
- Conversations with U.S. Cabinet officials, finance ministers and central bankers
Beyond the stage, the value for many attendees is access: bilateral meetings, on-the-record briefings and networking with public- and private-sector leaders who rarely share a room.

Kathy Warden’s age
