The Global Owners and Family Office Congress 2026 is the fourth edition of Campden Wealth's flagship global congress and the first of a three-year Abu Dhabi run, held 19–22 October 2026 at the Saadiyat Rotana Resort & Villas on Saadiyat Island, Abu Dhabi. The organiser's own congress page publishes the format plainly: a three-day meeting for Campden member families and global families of significant wealth, “infusing knowledge sharing, best practices, family showcases, future thinking and immersive networking”, under the 2026 theme “The Power of Family Capital to Deliver Change”, with published workshop and briefing tracks on family-business conflict management, women of wealth, co-investments, governance and values, plus participant-chosen roundtables and cultural and social events. Registration is invitation-only via the Campden Congress Connect App and eligibility is limited to qualifying family principals, next-generation members, single-family offices, family businesses and private investors, with the sessions held under Chatham House Rules. The organiser's own press release states that the Abu Dhabi Family Business Council (ADFBC), an affiliate of the Abu Dhabi Chamber of Commerce and Industry, signed an agreement with Campden Wealth to host the Congress in Abu Dhabi for three consecutive years (2026–2028), and that the Congress “will convene leaders representing more than 350 ultra-high net worth individuals (UHNWIs) and their family offices from around the world” (the organiser's own figure, quoted, not asserted here). SCOPE, STATED HONESTLY: the organiser publishes no delegate list, no faculty roster and no attendance count for this edition (Chatham House Rules), so nothing here is an attendance list and no person is attributed to the Congress beyond the two official signatories of the hosting agreement, both named on the organiser's own press release. The venue pin is the organiser's own published venue, geocoded on OpenStreetMap/Nominatim - no fabricated address, no AI/diffusion geography. Public OSINT only; no invented attendees, net-worth or deals.
