BJJ Competition Roundup: What to Watch in September 2026

September 2026 is one of the busiest stretches on the jiu-jitsu calendar, with major events spread across three continents. Here's what's on deck this month and why each one matters.

IBJJF World Master Championship & Jiu-Jitsu Con — September 3–5

The 2026 World Master IBJJF Jiu-Jitsu Championship runs September 3–5 at the Las Vegas Convention Center, bringing Master 1 through Master 7 age divisions together for blue, purple, brown, and black belt world titles. The tournament overlaps with IBJJF's Jiu-Jitsu Con, combining vendor booths, seminars, and fan meetups with the Masters brackets — one of the busiest single weekends on the calendar outside of the adult Worlds.

ADCC World Championship 2026 — September 12–13, Krakow

The ADCC World Championship lands in Krakow, Poland on September 12–13, closing out a qualification cycle that ran through trials in Rio, Belgrade, and Pomona. Defending -65kg champion Ana Carolina "Baby" Vieira headlines a field that also includes a wave of first-time competitors chasing breakout runs. Expect streaming coverage on FloGrappling, with earlier portions likely free on YouTube.

BJJ Summer Week — September 16–20, Sardinia

BJJ Summer Week returns for its 11th edition, bringing over a thousand grapplers to Sardinia, Italy for a week of open-mat training, seminars, and coastal downtime between tournament cycles — a fixture for athletes and hobbyists looking to train abroad outside the competition circuit.

AJP Tour — Events Across Nine Countries

The Abu Dhabi Jiu-Jitsu Pro Tour keeps its regional championships running throughout September, with stops scheduled in Serbia, Brazil, Finland, Jordan, Angola, Portugal, Russia, Spain, and Paraguay — part of the tour's broader push to grow ranked competition access outside the traditional IBJJF and ADCC circuits.
