SEDEX 2026 will open on October 14 with 300 companies participating, according to THE ELEC, Korea's electronics industry media outlet.

The confirmed exhibitor count positions the Seoul-based show, organized by the Korea Semiconductor Industry Association, as one of the country's largest annual gatherings for the chip supply chain. The event brings together equipment makers, materials suppliers, fabless companies and foundry-adjacent service providers under one roof.

For international semiconductor suppliers, the 300-company figure signals how much exhibition demand in Korea has recovered and grown since the industry's 2023 downturn. Korea hosts two of the world's largest memory makers — Samsung Electronics and SK hynix — and their capex cycles drive a substantial domestic ecosystem of subcontractors, fab-equipment vendors and materials firms that exhibits at SEDEX target directly.

The show's timing also matters. It arrives as Korean chipmakers ramp spending on advanced DRAM and HBM capacity to serve AI accelerator demand, pulling their supplier base — much of it represented at SEDEX — into parallel expansion.

Details on floor space, venue specifics and the full exhibitor breakdown were not disclosed in the announcement. Organizers typically publish the participation list and conference program in stages ahead of the opening.

SEDEX 2026 runs from October 14; additional exhibitor and program confirmations are expected in the run-up to the event.
