ChatGPT's parent company—OpenAI—is expected to go public soon, joining other AI heavy-hitters that are also believed to be targeting 2026 IPOs, including Anthropic and SpaceX. Here's what we know about the OpenAI IPO and how to buy in from Canada.
OpenAI is planning an IPO, although it has not yet filed a viewable Form S-1 prospectus with the US Securities and Exchange Commission (SEC).
Rumours of an IPO began circulating in 2025 when unidentified sources familiar with the matter said the company is making plans to go public in the second half of 2026 in the hope of raising $60 billion or more.
Outside analysts expect OpenAI to be valued as high as $1 trillion after the IPO, making it one of the largest public offerings in history. In the first quarter of 2026, it was valued at $852 billion after raising $122 billion from private investors.
Details like the stock exchange, ticker symbol, volume of shares and expected share price are unknown. We'll update this page with more information as it becomes available.
Note: All dollar amounts on this page are in US dollars unless otherwise stated.
Once OpenAI goes public, you'll need a brokerage account to invest. Consider opening a brokerage account today so you're ready as soon as the stock hits the market.
You won't be able to buy OpenAI stocks on a Canadian stock exchange like the TSX. Instead, you need a Canadian broker that provides access to international stock exchanges.
You can access US exchanges like the NYSE and the NASDAQ using Canadian trading platforms like Qtrade, Wealthsimple, Scotia iTRADE and CIBC Investor's Edge.
Interactive Brokers provides access to many stock exchanges outside North America like the Hong Kong Stock Exchange (SEHK), Korea Stock Exchange (KSE), National Stock Exchange of India (NSE), Frankfurt Stock Exchange (FWB) and London Stock Exchange (LSE).
It's impossible to predict how any stock will perform — and IPOs can be particularly volatile. Looking at the performance of similar companies can help you decide if now is a good time to buy OpenAI stock.

Canadians who earn dividends from US stock investments must pay the US Internal Revenue Service (IRS) a 15% withholding tax on their earnings. The rate goes down to 10% for bonds and other interest-yielding US investments.
An exception is made for stock investments held in trusts designed to provide retirement income. This includes RRIFs, LIRAs, LIFs, LRIFs and Prescribed RRIFs. RRSPs that hold US stocks, bonds or ETFs are also exempt from US withholding tax. RESPs, TFSAs and RDSPs are not exempt.
Canadian and international investment income must be declared on your Canadian tax return. Unless your US earnings are exempt from withholding tax, this means you'll be taxed by both the IRS and the CRA. The CRA may allow you to claim foreign tax credits for any taxes you've already paid to the IRS.
