2026 is shaping up to be the year AI goes public. Three of the most valuable private companies in history are racing toward IPOs, and the scale of capital involved has no precedent.
Here is where each one stands and what it means for investors.
OpenAI: $852 billion valuation, leadership tensions, and a Q4 target
OpenAI just closed a $122 billion funding round at a post-money valuation of $852 billion. SoftBank co-led alongside Andreessen Horowitz and D.E. Shaw Ventures. Amazon, Nvidia, and Microsoft all participated. About $3 billion came from individual investors through bank channels for the first time.
The numbers behind the company: $25 billion in annualized revenue as of February 2026. ChatGPT now has over 900 million weekly active users. 50 million paying subscribers, including 9 million business customers. The company generates $2 billion in revenue per month.
CEO Sam Altman wants the IPO to happen as early as Q4 2026.
But there's a problem. According to The Information, CFO Sarah Friar has told colleagues she doesn't think OpenAI will be ready to go public this year. She's raised concerns about the company's financial exposure from steep spending on computing infrastructure. OpenAI has committed over $600 billion in cloud server capacity over the next five years.
The tension appears to go deeper. Reports indicate Altman has been excluding Friar from some conversations with investors and from meetings involving important financial decisions. Friar stopped reporting directly to Altman last year and now reports to Fidji Simo, the former Instacart CEO who runs OpenAI's applications business.
Both executives released a joint statement saying they are "fully aligned" on compute strategy. Whether the market believes that alignment is genuine will matter when the S-1 drops.
One critical detail investors should watch: OpenAI doesn't expect to be cash flow positive until 2029. The company will spend upwards of $200 billion before it begins generating cash. That's a long runway of losses for public market investors to stomach.
Anthropic: $380 billion valuation, $19 billion revenue, and an October target
Anthropic is the quieter but arguably more compelling IPO story.
The company closed a $30 billion funding round in February at a $380 billion valuation. It's now in early discussions with Goldman Sachs, JPMorgan, and Morgan Stanley about a potential October 2026 listing that could raise over $60 billion.
The revenue growth is staggering. Anthropic's annualized revenue hit $19 billion by March 2026. That's up from $9 billion at year-end 2025 and roughly $1 billion in December 2024. Revenue has grown more than 10x annually for three consecutive years.
What makes Anthropic different from OpenAI: roughly 80 percent of its revenue comes from enterprise customers, not consumers. It has over 300,000 business customers. Eight of the Fortune 10 use Claude. Claude Code, the company's coding tool, alone generates over $2.5 billion in annualized revenue.
Anthropic was founded in 2021 by former OpenAI researchers, including CEO Dario Amodei and his sister Daniela Amodei, who left over disagreements about safety and commercialization. That origin story now has market implications. Investors and AI users have drawn contrasts between the two companies' approaches to government partnerships and safety, which could influence how capital is allocated if both IPOs launch in a similar window.
The key risk with Anthropic is cost. The company plans to spend $19 billion on training and inference in 2026, roughly matching its total revenue. Gross margins fell to 40 percent after inference costs surged beyond projections.
SpaceX: Already filed, targeting June
We covered this in detail earlier this week. SpaceX filed confidentially with the SEC on April 1st and is targeting a June listing at approximately $1.75 trillion. It would be the largest IPO in American history by a wide margin.
The SpaceX IPO is relevant to the AI story because its merger with xAI means a significant portion of the raise will fund AI infrastructure. Musk wants to compete directly with OpenAI and Anthropic, and SpaceX's Starlink profits are now subsidizing that ambition.
How to think about exposure right now
None of these companies are public yet. But several public companies have meaningful stakes that give investors indirect exposure today.
Amazon holds an approximately $8 billion stake in Anthropic and is a lead investor in OpenAI's latest round. Alphabet invested $900 million in SpaceX in 2015 and holds roughly $3 billion in Anthropic. Nvidia supplies chips to all three companies and benefits from every dollar they raise and spend on compute. Microsoft remains OpenAI's largest strategic partner.
ARK Invest recently acquired a $240 million stake in OpenAI through its ARKK, ARKF, and ARKW funds. Retail investors looking for pre-IPO exposure are also using funds like Destiny Tech100 and the KraneShares AI and Technology ETF.
The VonTrend bottom line
The AI IPO wave could put well over $100 billion in new capital into the market before year-end. SpaceX targeting June. OpenAI potentially in Q4. Anthropic potentially in October. Nothing like this has ever happened in a single year.
The question for investors is not whether AI is real. It is whether these valuations are sustainable for companies that are either unprofitable or spending every dollar they earn on infrastructure. OpenAI won't be cash flow positive until 2029. Anthropic is spending as fast as it's earning. SpaceX is subsidizing an AI arms race with satellite internet profits.
When the S-1 filings become public, the real numbers will speak for themselves. Until then, the smartest approach is to understand the landscape, watch for the filings, and resist the urge to chase hype or run from fear.
We will be tracking all three IPOs closely as details emerge.
