hi. does anyone know how i can go about buying shares in an ipo before the launch date?
There are companies like PrimaryBid which you can look into but currently Freetrade is not integrated into them.
There is a thread on this forum for PrimaryBid integration discussion also.
do you by any chance know if coupang will list on freetrade?
No, however they do add new stocks every week usually and they post those here to the community when they happens.
As for IPOs, I am unsure.
