The EU has denied that foreign affairs chief Kaja Kallas will attend Dialog, the secretive society event hosted by German-American billionaire and Palantir co-founder Peter Thiel, after a leak revealed her name on the list of attendees.

EUobserver has learned that she is not a member of the organisation and is not planning to attend the event, which is expected to take place from 12–16 August near Dublin, Ireland.

Whether she was invited to take part in this retreat or not remains unclear.

The attendees list, leaked on Tuesday (16 June) and featuring more than 200 world leaders and tech tycoons, includes other big names such as trillionaire Elon Musk, former US army general Stanley McChrystal, US treasury secretary Scott Bessent, co-founder of KKR Henry Kravis, the Saudi ambassador to the US Reema Al-Saud, and US senators Cory Booker and Ted Cruz.

Among the European names, there are also Germany’s MP Jens Spahn, British MP Tom Tugendhat, and Russia’s chess grandmaster and political dissident Garry Kasparov.

Surveillance and software moguls like OpenAI president Greg Brockman and Palantir cofounder Joe Lonsdale were included in the leaked list of 222 members.

EUobserver was unable to verify whether they will take part in the event.

The invitation-only society, simply known as Dialog, was co-founded in 2006 by Silicon Valley investor and CEO of PayPal Thiel, who was mentioned in the Epstein files.

The documents, from Department of Justice filings and congressional committees, reveal that Thiel and financier and sex trafficker Jeffrey Epstein maintained a relationship that began as early as 2014 and continued into early 2019, the year Epstein was found dead in his New York prison cell, in a death ruled suicide.

In 2014, the Dialog’s annual retreat extended an invitation to Epstein. 

The group’s “off-the-record” sessions during the event in August include “Bring Back Nuclear,” “How’s Your Sex Life?” and “Build-a-Cult,” as well as providing match-making services to its members, according to the report by Wired.

Dialog’s directory was first revealed by Swiss hacktivist Maia Arson Crimew. Crimew was not available for comments in time for publication.

Dialog’s members also included popular names from the creative sphere, such as Hollywood staple Joseph Gordon-Levitt, Oscar-winning songwriter Benj Pasek, among other writers, journalists, and academics.
