Fat Bear Week 2026 Semifinals Set After Wild Round 2
Fat Bear Week 2026 is roaring toward its conclusion. After a weekend pause, voting resumes Monday, September 28, with the semifinals of the 12th annual tournament at Alaska's Katmai National Park & Preserve. The champion will be crowned on Fat Bear Tuesday, September 29, capping a competition that has already drawn massive global attention and, at times, overwhelmed the official website with traffic.
The semifinal matchups feature four formidable contenders: Bear 164 (Bucky Dent) versus Bear 89 (Backpack), and Bear 132 and her cubs against Bear 910. These bears emerged victorious from Round 2, which concluded on September 25 with a series of decisive outcomes. Bucky Dent, an ace fisherbear known for snatching leaping salmon mid-air, defeated Bear 151 (Walker) in what Popular Science called the biggest battle of the round. Backpack crushed Bear 620 with more than 95 percent of the vote—the most lopsided result of the day. In a family face-off, Bear 132 and her cubs triumphed over Bear 806 and her cubs, while Bear 910 overcame her sister, Bear 909, in a head-to-head matchup.
The single-elimination bracket, styled after March Madness, pits individual bears and bear families against each other in daily votes. Fans worldwide can cast ballots at explore.org during designated voting windows—12 p.m. to 9 p.m. EDT (9 a.m. to 6 p.m. PDT, 8 a.m. to 5 p.m. AKDT). The bear or family with the most votes advances; the loser is eliminated. This year's competition began September 22 with 16 bears and bear families, each with a unique story of survival and fattening success.
Key Contenders and Their Stories
Bear 164, nicknamed Bucky Dent, has captured imaginations this summer with his acrobatic fishing skills, plucking salmon out of the air. His Round 1 victory over Bear 32 (Chunk)—the 2025 champion—was a major upset, signaling a changing of the guard. Chunk had been recovering from a broken jaw and was seeking to defend his title, but Bucky's impressive weight gain and agility proved too much.
Bear 89, known as Backpack, enters the semifinals after a dominant performance. A regular at Brooks River, Backpack has packed on serious mass ahead of winter hibernation. His matchup against Bucky Dent promises to be a clash of titans.
Bear 132, a first-time Fat Bear Week participant, has one of the most compelling narratives. This summer, one of her three spring cubs became separated from the family and wandered alone for several days near Brooks River. The cub attempted to approach other bear families but was chased away. Cubs without a mother's protection face starvation and attacks from other bears. Miraculously, the cub survived and reunited with Bear 132 and its siblings. Her resilience and successful raising of three cubs have endeared her to voters.
Bear 910 advanced after defeating her sister, Bear 909, in an emotional matchup. Bear 909 had lost both of her cubs this season, including one killed and eaten by Bear 806 on July 28—a rare and shocking event captured on live webcams. Bear 806, who also adopted an abandoned cub named Biggie, was eliminated by Bear 132 in Round 2. The complex family dynamics have added drama to this year's competition.
The Stakes: Why Fat Bear Week Matters
At its core, Fat Bear Week is a celebration of survival. Brown bears in Katmai must consume tens of thousands of calories daily during the summer and fall to build fat reserves for winter hibernation. The fattest bears are often the healthiest, best prepared to endure months without food. The contest highlights the importance of salmon-rich rivers and abundant natural resources in the park, which spans 4.1 million acres of volcanoes, forests, and waterways.
"For each match-up, vote for the bear you believe best exemplifies fatness and success in brown bears," the competition's website states. Success, in this context, means surviving and thriving in a harsh wilderness. The public's enthusiasm has grown exponentially since the event's humble beginnings.
From One-Day Experiment to Global Phenomenon
Fat Bear Week began in 2014 when former Katmai ranger Mike Fitz noticed a fan's side-by-side photos of the same bear in June and September on the park's live bearcam feed. The dramatic weight gain inspired "Fat Bear Tuesday," a one-day Facebook event where votes were counted via likes. The response was overwhelming, prompting the National Park Service and Explore.org to expand it into a weeklong tournament in 2015.
In 2025, more than 1.7 million votes were cast from over 100 countries. This year, individual matchups are already pulling six-figure totals, and the official site has occasionally buckled under the traffic. The event has become one of the most successful public wildlife engagement initiatives in the world, drawing attention to Katmai's bears and the broader challenges facing wildlife in a changing climate.
2026 Competition Highlights
This year's bracket features 16 entrants, including 2025 champion Chunk, who was eliminated in Round 1 by Bucky Dent. Other notable bears included Bear 151 (Walker), known for his mighty rear end; Bear 806, whose controversial predation on a cub sparked widespread discussion about natural bear behavior; and Bear 909, who persevered despite losing both cubs. The presence of multiple mother-cub teams—Bear 132, Bear 806, and others—has added a generational dimension, with park superintendent Mark Sturm noting, "There are more cubs at Brooks Camp this year than have been seen in a long time. A new generation of fat bears is taking shape, and they're off to a strong start."
Perspective: More Than a Popularity Contest
While Fat Bear Week may appear to be a lighthearted internet meme, it serves a deeper purpose. The event educates millions about brown bear biology, hibernation, and the importance of preserving wild spaces. Katmai National Park is roadless, accessible only by boat or plane, making the live webcams a vital window into this remote ecosystem. The tournament fosters a connection between people and nature, encouraging conservation awareness.
The competition also highlights the raw realities of the wild. Bear 806's killing of a cub, witnessed on live cam, reminded viewers that nature is neither sentimental nor scripted. Such events, while difficult to watch, are part of the natural order and underscore the challenges bears face. The adoption of Biggie by Bear 806 further illustrates the complex social dynamics of brown bears.
As the semifinals begin, fans are eagerly casting votes and debating the merits of each bear. Will Bucky Dent's fishing prowess and momentum carry him to victory? Can Backpack's sheer bulk prevail? Will Bear 132's inspiring family story win hearts? Or will Bear 910 cap a season of tragedy with a triumphant title? The answers will unfold by September 29.
For those who haven't yet voted, there's still time to participate in this global celebration of fatness, survival, and the wild beauty of Alaska. Whether you're a longtime fan or a newcomer, Fat Bear Week offers a delightful escape and a reminder of the incredible creatures with whom we share the planet.
In a world often dominated by grim headlines, Fat Bear Week is a rare feel-good story that also informs and inspires. As the tournament reaches its climax, one thing is certain: the bears of Katmai have already won by being fat, healthy, and ready for winter.
