Up to now, there are many rumors in the market that the CSRC is preparing to restart the ipo in May, which means that it has begun to accept the listing application of new companies. This means restarting.
But the fact is that on April 23, someone from the CSRC came out to clarify that there was no such plan. So when exactly, it is not clear. (See Securities News on the 23rd)
To correct you, when you say ipo, you should mean to start issuing new shares. This statement is half right.
There are two kinds of ipo, one is that unlisted companies want to go public, and the first IPO is IPO.
One is that listed companies issue new shares, which is called additional issuance.
Full name of ipo: initial public offering and listing.
