What is an IPO?

IPO stands for, Initial Public Offering and as the name suggest this is the first time shares in a private company have been offered to the public for investment.

Example: Google (now Alphabet) IPO’d in 2004 for $85 / share

Of course not all IPOs will do as well as Google, but you get the point.

Access to IPOs

The IPO process is typically managed by investment banks and stockbrokers, who prepare the private company to become a listed company on the stock exchange.

The investment banks and stockbrokers leading the IPO would have first dibs at offering the shares to their best clients.

If an IPO was considered highly sort after, such as Google or Facebook, often all the shares would be allocated to existing clients and none for other investors. That was until now.

3. The Bidding Process

If you are interested in making a Bid, you will be taken to a screen showing a link to the Prospectus.

The Prospectus is the formal IPO document and outlines all the information required to help investors make an informed decision about the shares they are buying.

It is strongly recommended that you read the Prospectus in full and be familiar with what you are investing in.

Here are some frequently asked questions about the service:

Q: Will I Get What I Bid For?

A: Not always. The company that is listing has ultimate say over the allocation of their shares.

If a IPO is particularly sort after, then it classes as ”oversubscribed”, which means there were far more bids then there were shares available. In this case you may only be allocated a portion of shares you bid for (if at all).

On the flip side, if there is not enough demand from investors, the IPO is said to be ”undersubscribed” and if the company cannot find more investors they may have to cancel the IPO and refund your money.

Q: When Do I Have to Pay?

A: Using OnMarket you can bid now and pay later.

The prospectus will outline the key dates for the IPO and OnMarket will inform you when you need to transfer funds to ensure your bid is ”live”.

You can easily transfer funds using BPAY.

Q: How Do I Get My IPO Shares?

A: Via your HIN number. If you were successful in your bid for IPO shares, you will be allocated the shares via the ASX CHESS system.

Under the CHESS system, each investor with an active broking account is issued a Holder Identification Number or HIN.

IPO shares will be allocated directly to the broking account associated with your HIN before the shares start trading on the ASX.


Q: Can I Cancel my Bid?

A: Yes. Using OnMarket it is possible to cancel your bid.

Sometimes the IPO process may take longer than expected, or new information becomes available and you decide the IPO is no longer for you.

Simply click the bid history tab and elect to cancel your bid. Your funds will be refunded into your account within a couple of days.
