How to buy US IPO using a Singapore account?

Hello Fu Chun!

You should check with your online brokerage whether they are the ones who will be allowed to distribute the IPO stock.

For example TD Ameritrade:

"On occasion, TD Ameritrade will act as a member of the selling group for IPOs. When we do, we can offer qualified accounts the opportunity to participate. When we aren't, we can still offer you the opportunity to pursue investing in a company entering the market once it goes public. Once you open and fund an account, you can purchase a recently listed stock on the secondary market, as long as you decide it fits with your strategy."

Buying the next wave:

If you use any online brokerages which allow you to trade in the US stock market, you should be able to trade the stock once it is listed.​​​
