ASCO Annual Meeting: common questions

Who attends ASCO Annual Meeting?
Oncology clinicians, researchers and healthcare professionals, together with industry exhibitors and sponsors. The organizer reports more than 44,000 total ASCO25 attendees from 166 countries.
Is there an exhibitor list for ASCO Annual Meeting?
Yes. The organizer publishes the exhibitor list. The official 2027 Exhibit at ASCO page says over 450 organizations will exhibit. This is an organizer forecast, not a final result. The homepage separately labels 7,400 as Exhibitors in its ASCO25 section without clarifying whether this means staff. The official 2027 floor plan labels 553 exhibitors on 22 October 2026, but its table repeats companies across booth and meeting-room entries; that figure is not treated as a verified unique-company count.
Can I get the attendee list for ASCO Annual Meeting?
Organizers rarely publish one. EarlyHall builds it from public sources: exhibitor and speaker pages and social posts, plus the event app when you give us access. Each person is tagged with their role at the event and the source we found them in, and a listing is never presented as confirmed attendance. Lists start at $349 per event.
