Podcast Guest Statistics 2026: How Often Shows Book Guests, and Who Gets Booked Most

In a random sample of 30,049 English-language episodes published in 2026 and transcribed by CastFox, 40.5% include at least one guest, meaning a person other than the show's hosts. Across all languages the figure is 39.2%.

So the interview format is common but not the majority. Most episodes are host-only: solo shows, co-host conversations, narrative episodes, sermons and news rundowns.

Interview-driven genres sit at the top. Science, Business, Arts shows bring in an outside voice in more than half of their episodes: researchers, founders, authors and artists explaining their work. News sits near the average at 40.3%, but there "guest" includes interview segments and clips, not only booked conversations. At the bottom, Fiction, Religion & Spirituality, Comedy shows are mostly built around the host's own content: stories, sermons or banter between regular co-hosts.

When an episode has a guest, it usually has exactly one. The average is 1.28 guests per guest episode, and 17% feature two or more, typically panels, roundtables and comedy shows with several comics.

We counted how many different shows each person appeared on as a guest between January and September 2026. To keep the list honest, we only counted appearances where the guest's name is in the episode title, and we left out News and Government shows, where politicians mostly appear in clips and coverage rather than booked interviews.

The list is dominated by people with something new to talk about. Episode titles show several of the leaders on book tours: Eric Ries discussing Incorruptible, Nir Eyal on Beyond Belief and David Epstein on Inside the Box. By the genre of the shows they appeared on, Health & Fitness (7), Business (6), Comedy (5) are the largest groups in the top 25: health and longevity experts, business and self-improvement authors, and stand-up comedians.

• Pitch the genres that book guests. In Science, Business, Arts, more than half of episodes have a guest. In Fiction or Religion & Spirituality, most shows rarely book anyone, whatever your pitch.
• Have a hook. The most-booked guests are promoting a book, a special or a new idea. Hosts book a reason to talk, not just a résumé.
• Check the show first. A show's recent guest history tells you more than its genre. If it hasn't had a guest in months, it probably isn't looking.

CastFox's Guest Finder scores how open each show is to guests from its recent episodes, and finds shows that have booked guests like you. See also podcast guesting with CastFox.
