Summary

OpenAI is reportedly planning a confidential IPO filing in the coming weeks, targeting a September 2026 listing with an estimated US\$1 trillion valuation. This follows a recent private fundraising round valuing the company at US\$852 billion and US\$186 billion already raised. The move comes as SpaceXAI also prepares for a June IPO with a US\$1.75 trillion valuation, setting a benchmark for investor interest in AI. Despite ChatGPT commanding 54% of Gen AI traffic and having over 900 million weekly active users and 50 million subscribers, OpenAI faces profitability challenges, burning more cash than it generates. Major investment banks like Goldman Sachs and Morgan Stanley are advising on the offering, which could seek to raise at least \$60 billion. Bank of America Securities warns that a trifecta of mega AI IPOs, including OpenAI, could push tech stock concentration in the S&P 500 to 48%, signaling a potential AI bubble reminiscent of past market peaks.

Key takeaway

For investors considering AI sector exposure, OpenAI's impending US\$1 trillion IPO and the broader AI market's high valuations demand careful scrutiny. You should assess the long-term profitability of AI firms, as many, like OpenAI, still burn significant cash despite user growth. Diversify your portfolio beyond concentrated tech stocks to mitigate risks associated with a potential AI bubble, as warned by BofA Securities.
