The Shark Week 2026 host question has a twist this year: Discovery is skipping a single master of ceremonies altogether. Instead, the network’s 38th annual event, running Sunday, July 26 through Saturday, August 1, 2026, spreads hosting duties across a rotating cast of celebrities, scientists and conservationists.
That’s a real departure from recent years, when one big name carried the entire week. Here’s exactly who’s involved, what happened to the tradition of a single host, and what each key figure brings to the 2026 lineup.
Why Shark Week 2026 Doesn’t Have One Host
For several years running, Discovery leaned on a single celebrity face to anchor the entire event. John Cena hosted in 2024, Jason Momoa took the reins in 2023, and Dwayne “The Rock” Johnson fronted the franchise in 2022. That format, often called the “master of ceremonies” approach, began in 2022.
Shark Week 2026 breaks from that pattern. There is no overarching presenter stitching the week together this time. Instead, Discovery has built each night around the specific experts, athletes and celebrities featured in that night’s specials, letting the subject matter drive who appears on screen.
Ken Jeong and REI AMI Open Shark Week 2026
The closest thing to a marquee hosting moment this year belongs to opening night. Actor and comedian Ken Jeong teams up with Grammy-nominated singer REI AMI for “K-Pop Shark Heroes,” which premiered Sunday, July 26, at 8 p.m. ET/PT.
The special leans into the “KPop Demon Hunters” phenomenon, with Jeong and REI AMI investigating a recent string of shark encounters off the Korean Peninsula. Their goal is to reshape global perceptions of sharks using K-pop’s massive cultural reach, giving the season opener a distinctly different energy than past Shark Week premieres.
The Scientists and Experts Leading Individual Specials
Beyond the celebrity-driven opener, Shark Week 2026 features a deep bench of recurring shark experts guiding viewers through the science-heavy specials:
- Josh Gates – The “Expedition Unknown” host returns to dive into the history behind some of the most infamous shark encounters ever recorded.
- Paul de Gelder – A shark-attack survivor and advocate, de Gelder teams up with apex predator specialist Rosie Moore to investigate what triggers aggressive bull shark behavior in Jupiter, Florida.
- Molly Carlson – The high diver attempts a record-setting plunge into shark-infested waters in “Ultimate Shark Dive.”
- Forrest Galante – The wildlife biologist continues his recurring role across multiple Shark Week investigations.
- Dr. Tristan Guttridge – A marine biologist who, alongside cinematographer Kina Scollay, documents competing groups of great whites off New Zealand.
- Dr. Craig O’Connell – A conservation biologist featured in specials examining shark tail-strike behavior and feeding patterns.
How This Compares to Past Shark Week Hosts
Shark Week has used a range of hosting formats since debuting in 1988. Recent single-host years included:
| Year | Host |
|---|---|
| 2022 | Dwayne “The Rock” Johnson |
| 2023 | Jason Momoa |
| 2024 | John Cena |
| 2025 | No single host announced ahead of premiere |
| 2026 | Rotating lineup, no single host |
This marks the second consecutive year Discovery has moved away from a lone celebrity host, suggesting the network may be settling into a format built around subject-specific experts and guest stars rather than one recurring face for the whole week.
