Organized by Tap Cancer Out
October 10, 2026 brings Tap Cancer Out's Chicago BJJ Open, a no-gi submission grappling tournament raising funds for cancer research. The event continues Tap Cancer Out's tradition of combining competition with charitable giving.
Tap Cancer Out's Chicago stop keeps the same charity-driven format the nonprofit has run since 2011: gi-only competition under IBJJF rules with a couple of athlete-friendly tweaks, including optional rashguards and no requirement for spats under gi pants. The organization has funneled more than $7.75 million since 2012 to cancer research and support charities, including the Leukemia & Lymphoma Society, St. Baldrick's Foundation, and PanCAN. The Chicago BJJ Open runs Saturday, October 10, 2026, with double-elimination gi brackets for every belt and age division. Brown and black belts compete free, as do competitors who raise $250 or more for the cause; everyone else registers through the event's Smoothcomp listing.
Tap Cancer Out is a jiu-jitsu-community 501(c)(3) nonprofit that has run BJJ tournaments since 2012, channeling the sport's competitive energy into cancer fundraising — competitors fundraise for free tournament entry at gi and no-gi events for all ages and belts. Since 2012 it has supported 25 beneficiary organizations and raised over $9 million for cancer research and patient support.
Tap Cancer Out is a 501(c)(3) nonprofit that runs BJJ tournaments to raise money for cancer-fighting organizations — competitors fundraise as part of registration, and event proceeds are donated. Events offer gi and no-gi divisions for kids and adults across belt levels.
On the mat, matches run under a points-based ruleset that follows familiar IBJJF-style scoring conventions, so competitors coming from IBJJF or similar events will recognize the point values and structure. Review Tap Cancer Out's published rulebook for the specific modifications in effect for your division.
Always confirm the official rulebook before you compete — organizations update rules between seasons. See the official event page for current rules.
