Early Years (2013–2016)

Founded and hosted by the Orange Kettlebell Club (OKC) in California, the California Open quickly became a magnet for athletes across the U.S. and abroad. It helped establish kettlebell sport in North America by combining professional-level judging with a welcoming atmosphere for newcomers.

WAKSC Era (2017–2018)

In 2017 and 2018 the California Open partnered with the World Association of Kettlebell Sport Clubs (WAKSC) and served as the official WAKSC World Championship. This partnership elevated the event to true world-stage status, bringing record-setting performances and strong international participation.

IKO / World League Era (2019–2025)

Starting in 2019, the California Open entered a new phase through collaboration with the International Kettlebell Organization (IKO) and its Kettlebell Sport World League. From then on, the event also doubled as the IKO World Championship for Clubs & Individuals, becoming a fixture on the global competition calendar.

Even during the pandemic years, IKO innovated with hybrid formats (in-person + online submissions), ensuring athletes worldwide could still participate. Annual results confirm robust international participation across weight classes and ranks, from grassroots athletes to Master of Sport International Class (MSIC).

Transition After 2025

Following the California Open x IKO World Championship 2025, the Orange Kettlebell Club closed operations. To preserve the legacy and continuity of the event, the rights to run the California Open were formally transferred to IKO. From 2026 forward, the California Open continues under IKO’s direct leadership — ensuring the event’s place as both an elite World Championship and a community-building event of kettlebell sport in North America.
