2026 DDP Children’s Economy Market Dates, Hours, Parking – What to Know Before Visiting the Kids’ Seller Flea Market

On the Hangul Day holiday Saturday,
a flea market where kids sell their own goods
will open at DDP 🧸

DDP Win-Win Market: Children’s Economy Market
will be held for 3 hours
on October 10 (Sat) from 13:00 to 16:00
in the outdoor space of Dongdaemun Design Plaza (DDP).

Here’s a summary of the September 28 event notice
and seller recruitment announcement
from the Seoul Design Foundation DDP website.

🎪 What Kind of Event Is This?

Children become sellers themselves
and buy, sell, and share items like
toys and books at this market.

Through this experience, they naturally learn
about economic concepts and resource circulation
in a hands-on event.

Sellers were recruited on a first-come, first-served basis
for 1,000 teams consisting of families with children
aged 5 to 12.
Recruitment has ended, and
final participants were notified by text on September 29.

The notice states
’Buyers can visit freely.‘
Admission is also free.

In Seoul’s October event plan,
it’s listed as part of the ‘DDP Design Play’ program.

🛍️ What Items Will Be Sold?

Here’s a table of what can and cannot be sold.

Children set the prices themselves.
They are encouraged to price items appropriately for the event,
and each item should have a price tag.

Each seller’s spot is 1.5m by 1.5m per application.
With paper and crayons provided on site,
kids name their market stall and
make signs, menus, and price tags.

Children do the selling,
while guardians only assist.
The recruitment notice encourages
voluntary donation of proceeds.

⏰ What Happens When?

Here’s a table of the schedule, from seller check-in to sales and the parade on the same day.

The parade starts at the 1st floor plaza of Hyundai Outlet Dongdaemun
and continues around the DDP area.

Seoul’s October event plan and
the September recruitment notice listed
the time as 11:00~17:00,
and the location as ‘from Oullim Square to Palgeori Slope.‘
The final notice on September 28
set sales from 13:00~16:00 in the ‘DDP outdoor space,‘
so this follows the latest update.
