Messari's fourth and last Mainnet, themed 'Then They Join You', ran 30 September - 2 October 2024 at Pier 36 in Manhattan, with Katie Haun, Multicoin's Tushar Jain, 1kx's Diana Biggs and Mysten Labs' Evan Cheng on the programme. No 2025 edition was held.
Messari did not stage a Mainnet in 2025: the organiser's mainnet.events domain still redirects to the 2024 page and no 2025 edition was announced. The entry is kept as the record of the final edition. Source: events.messari.io (2024 site via Wayback), checked 4 Sep 2026.
