株用語のIPOは Initial Public Offering の略で、日本語では『新規株式公開』と言われています。
ネットで見た英語での説明では
An Initial Public Offering (IPO) is when a private company offers shares to the public for the first time, allowing it to raise money from investors and become publicly traded. IPOs can give investors early access to growing companies, but they can also come with added risk and price volatility.
