A private funding round, which is when a company raises money by selling ownership stakes to select investors before its shares trade publicly, could value OpenAI at $1.2 trillion. Sam Altman's artificial intelligence start-up is weighing the raise ahead of a stock market listing, looking to capitalize on demand for its technology following recent model launches.

The $1.2 trillion figure is a valuation, not a revenue or profit number. In plain terms, it represents what investors would collectively agree the company is worth today in exchange for their capital. Whether OpenAI's actual business performance justifies that number is the open question any deal would need to answer.

The funding round would come before an IPO. An initial public offering is when a private company first sells shares to ordinary investors on a stock exchange, opening ownership to the general public for the first time. Raising capital privately ahead of that moment is a way to establish a price benchmark before the wider market gets a vote.

What was signed versus what is only projected matters here. The round is described as something OpenAI is weighing, not something it has closed. Sam Altman's company sees demand for its technology, driven by recent model launches, as the rationale for moving now.
