From Grok:

The first-ever White House Crypto Summit, scheduled for Friday, March 7, 2025, hosted by President Donald Trump, will bring together key figures from the cryptocurrency industry and government officials. As of the latest available information, the following attendees have been confirmed for the event:

Donald Trump – President of the United States, who will host and deliver remarks at the summit.

David Sacks – White House AI and Crypto Czar, chairing the summit.

Bo Hines – Executive Director of the President’s Working Group on Digital Assets, administering the event.

Brad Garlinghouse – CEO of Ripple (XRP), confirmed via hints in his own statements and reports.

Michael Saylor – Executive Chairman of MicroStrategy (BTC), a prominent Bitcoin advocate.

Matt Huang – Co-founder of Paradigm, a crypto investment firm, confirmed via his own announcement on X.

JP Richardson – CEO of Exodus, a self-custodial crypto wallet provider.

Sergey Nazarov – Co-founder of Chainlink, confirmed through reporting by Cointelegraph.

Kyle Samani – Managing Partner of Multicoin Capital, confirmed via his own tweet.

David Bailey – CEO of BTC Inc., suggested through his retweet of Michael Saylor’s attendance confirmation.

Additionally, the summit will include members of the President’s Working Group on Digital Assets, though specific attendees beyond Bo Hines and David Sacks are not fully detailed. Reports indicate the working group comprises key government figures such as Treasury Secretary Scott Bessent, Commerce Secretary Howard Lutnick, Attorney General Pam Bondi, the SEC Chair, and the CFTC Chair, among others. However, it’s unclear which of these individuals will attend beyond Hines and Sacks.
The event is expected to have more than 25 participants, including a mix of crypto executives and government representatives, according to Fox Business reporter Eleanor Terrett. Confirmed attendees from the crypto industry are limited to the 10 listed above as of March 5, 2025. Other speculated attendees, such as Brian Armstrong (CEO of Coinbase), Vlad Tenev (CEO of Robinhood), Arjun Sethi (CEO of Kraken), Paolo Ardoino (CEO of Tether), or additional figures like Cathie Wood (ARK Invest), Vitalik Buterin (Ethereum), or Charles Hoskinson (Cardano), have not been officially confirmed based on available data. Some X posts and articles suggest broader attendance, but these lack consistent verification across reliable sources.
The White House has not released an official, comprehensive guest list, and plans remain subject to change as the event approaches. More details may emerge closer to or during the summit itself. For the most current and complete list, checking official White House announcements or updates from attendees on platforms like X after March 7 would be necessary, as my information reflects the state of knowledge as of March 5, 2025.
