It is that time of year again when wildlife enthusiasts, conservation followers, and internet culture aficionados across the globe turn their attention to the pristine wilderness of Katmai National Park in Alaska. As the autumnal chill begins to settle over the landscape, fat bear lovers everywhere are preparing to cast their votes in the annual competition designed to see which bruin will emerge supreme as the plumpest, most successful feeder and the most likely to survive the harsh winter months ahead.
The highly anticipated competition, organized and put on by the National Park Service, shines a spotlight on some of the largest brown bears on Earth. These magnificent animals make their home at the park’s Brooks River during a critical biological period known as hyperphagia. During this intense phase of seasonal feeding, the bears consume massive amounts of calories to build up a heavy, insulating layer of fat that will keep them warm and sustain their bodies through the glacial, dormant months of winter hibernation.
The tournament format, which utilizes a bracket-based single-elimination system, has grown exponentially since its humble beginnings in 2014. When the event first started, roughly 1,000 votes were cast by a small group of dedicated park webcam viewers. In stark contrast, last year’s competition drew an astonishing 1.7 million votes collected from participants all over the world. The bears go head-to-head in figurative matchups, where the individual animal securing the most public votes advances to the next round until a single champion is crowned at the conclusion of the week.
This year, the official Fat Bear Week events are scheduled to kick off on September 22 and will run through September 29. The newly revealed 2026 bracket sets the stage for a dramatic week of online voting, featuring a wide array of bears categorized into specific groups, including family units, sub-adults, single adult females, and massive adult males.
The 2026 Fat Bear Bracket Revealed
The unveiling of the official bracket is always a moment of great excitement for followers who track the daily lives of the Brooks River bears throughout the spring, summer, and autumn months. The participants are carefully selected by park rangers and media teams based on their visibility, unique histories, and remarkable physical transformations throughout the season of hyperphagia.
Within the bracket, bears are sorted into distinct divisions that highlight the diverse demographics of the Katmai brown bear population. The family groups showcase dedicated mothers guiding and nurturing their spring cubs through the challenges of the river. The sub-adult category highlights younger bears who are navigating independence, learning vital fishing techniques, and figuring out their place in the complex social hierarchy of the river. Single adult females represent experienced independent bruins managing their own territories and resources, while the adult males division features some of the largest, most dominant bears on the continent, many of which tip the scales at well over a thousand pounds.
The Notable Bears Featured in the Tournament
To help voters understand the unique traits, histories, and personalities of the animals competing this year, observers have highlighted several standout contenders with distinct backgrounds. These animals not only display the impressive physical changes associated with hyperphagia but also demonstrate the complex behavioral dynamics that make observing Katmai’s brown bears so endlessly fascinating.
Among the prominent personalities in this year’s lineup is 32 Chunk, known widely as The Survivor. A large adult male brown bear, 32 Chunk is easily identifiable by a protruding brow ridge, a distinct scar across his muzzle, and a healed broken jaw that tells the story of a hard-fought life in the wild. He is deeply committed to his own survival and currently weighs in at an impressive 1,200 pounds, making him one of the largest and most formidable bears around the Brooks River and a notoriously difficult competitor to beat. As the defending Fat Bear Week champion, he enters the tournament with a massive target on his back.
Another compelling contender making her first appearance in the tournament is bear 806, recognized as The Fierce Protector. Throughout the summer months, 806 has been observed carefully guiding and caring for her own biological cubs, while also stepping up to take on orphaned cubs in need of a maternal figure. However, her nurturing side is balanced by a fierce, confident, and fearless demeanor when crossed. She knows how to stand her ground against rivals and is more than capable of defending her family unit, bringing a powerful dynamic to this year’s competition.
For those who lean toward charm and adaptability, bear 694 represents The Social Butterfly of the river. As a first-time contender, 694 is still too small to directly compete with the massive adult males for the prime fishing spots, but he more than makes up for it with his exceptional survival and fishing skills. Crucially, 694 thrives in a group setting, frequently making time to socialize and even engage in playful interactions with other bears while waiting for the salmon runs, all while successfully prioritizing the vital task of filling his belly for the winter.
Another fan favorite is 89 Backpack, aptly known as The Chill One. Earning his memorable nickname after being spotted hitching rides on his mother’s back through the river on multiple occasions, Backpack has matured into a remarkably even-tempered bear. Unlike some of his larger and more aggressive adult competitors, Backpack avoids unnecessary conflict. According to his official biography, while he is entirely capable of standing up for himself when the situation demands it, he prefers to use a quiet, calm strength to gain access to preferred fishing areas. He actively seeks out quieter spaces along the river and clearly knows how to put those peaceful environments to productive use, as evidenced by his dramatic physical transformation this year.
Rounding out the highlighted group is 151 Walker, known as The Strategist. During his earlier years as a sub-adult bear, Walker was known for having a laid-back attitude and was frequently observed playing amicably with other young bears. However, as he has grown substantially in size and confidence, his behavior has shifted. Walker is now much more willing to challenge other bears for resources, carefully sizing up his surroundings and making calculated tactical choices. While his substantial size makes him a formidable competitor, his increasing assertiveness has also brought him into more frequent pushback from other territorial bears along the river.
As voting commences on September 22, participants from around the world will weigh these distinct personalities, impressive physical transformations, and survival stories against one another to determine which bear ultimately claims the prestigious title of Fat Bear Week champion.
