Who's in the Room at ASCO26: Oncologists, Researchers, and the Full Care Continuum

The ASCO26 audience is unusually broad for a single-discipline conference, which is part of what makes it so valuable. Here's who you'll find on the floor and in the sessions:

• Medical oncologists and clinical researchers are the core constituency, attending to review trial data and update their practice protocols based on what gets presented.
• Oncology pharmacists and nurses who manage treatment delivery and patient education, increasingly involved in formulary and protocol decisions at institutional level.
• Healthcare administrators and hospital procurement leads evaluating new diagnostics, therapeutics, and IT platforms for adoption across their systems.
• Medical students and early-career researchers building their professional network and tracking where the science is heading.

The international composition is significant. Professionals from 166 countries attend, meaning exhibitors can expect substantive conversations with buyers and researchers operating under completely different healthcare systems and treatment guidelines.

What's on the Show Floor at ASCO Annual Meeting 2026: 7,400 Exhibitors Across the Oncology Stack

With over 7,400 exhibitors, the ASCO26 exhibit hall at McCormick Place is one of the densest concentrations of oncology-focused companies you'll find anywhere. The floor covers the full spectrum of cancer care innovation.

Pharmaceutical and biotechnology companies dominate in terms of space and foot traffic, presenting new therapeutics, combination regimens, and pipeline data that often mirrors or previews what's being discussed in the scientific sessions. Medical device and diagnostics firms bring imaging technologies, liquid biopsy platforms, and pathology tools that are central to how oncologists stage and monitor disease.

Healthcare IT and artificial intelligence companies have become an increasingly prominent presence, with platforms covering clinical decision support, real-world evidence generation, and oncology-specific EHR workflows. Clinical research organizations (CROs) and trial management platforms are also well-represented, targeting research teams looking to accelerate study recruitment and data capture.

If you're attending to evaluate solutions across more than one category, plan your floor time carefully. Seven thousand-plus exhibitors across McCormick Place is a serious logistical challenge.

Exhibitor Strategy at ASCO26: Standing Out in a Pharma and Biotech-Heavy Hall

The oncologists and researchers walking your booth have just come from a session presenting Phase III data. They are scientifically literate, pressed for time, and highly skeptical of marketing language. Lead with clinical evidence, not product positioning. If you're launching a diagnostic tool or AI-assisted platform, have published or peer-reviewed data visible and ready to discuss. A claim without supporting evidence will end the conversation before it starts.

Another common mistake: assuming that every oncologist at the booth is the right buyer. At ASCO26, the person who finds your technology compelling in a scientific conversation may not be the one controlling the budget. Identify procurement roles early in each interaction. Ask about institutional decision-making structure, and tailor your follow-up accordingly.

For teams managing high volumes of booth conversations across a five-day conference, capturing contact context in real time is worth planning for. Tools like Habsy let your reps record a quick voice note after each conversation, logging what the clinician was interested in, their institution, and their buying timeline. After three days of back-to-back conversations, that structured context is the difference between a useful follow-up and a generic email.

Visitor Tips for ASCO Annual Meeting 2026: Getting More Than CME Credits

If your primary reason for attending is the scientific program, build your session schedule around the late-breaking abstract presentations first. These are where the most practice-changing data gets unveiled, and the rooms fill fast. Prioritize your session list before you arrive.

For researchers evaluating partnerships or technology, the exhibit hall is most productive in the first two days when exhibitor teams are fully staffed and energized. By day four, the conversations get shorter. Target diagnostic and AI companies early if you're assessing tools for your institution, since these exhibitors often have hands-on demo stations that require uninterrupted time.

Keeping track of everyone you meet across a 44,000-person event is harder than it sounds. If an exhibitor hands you a card that's in a language other than English, or if you're collecting contacts from researchers across multiple countries, Habsy App scans cards in multiple languages and immediately pulls the person's LinkedIn profile and company context, so you leave the show with organized, searchable contacts rather than a stack of cards you'll sort on the flight home.

Why ASCO26 Belongs on Your 2026 Calendar

ASCO Annual Meeting 2026 is where clinical science, commercial oncology, and global research infrastructure overlap in one place for five days. For oncologists, it's the most efficient way to absorb a year's worth of pivotal trial data. For companies in pharma, biotech, diagnostics, and healthcare IT, it's direct access to the professionals making treatment and procurement decisions at institutions worldwide. The combination of scientific rigor and commercial scale makes it unlike any other event in the sector.

Before you arrive in Chicago, set up your lead capture and contact workflow so you're not losing conversations to poor notes or missed follow-ups. The Habsy Platform lets exhibitor team leads track every contact captured across the floor in real time, see which high-value prospects haven't been followed up, and compare lead quality across your show appearances. Get it configured before May 29.
