In the entire history of global financial markets, there has never been a single calendar year like the one we are living through. Three companies — each a category-defining force in technology, space, and artificial intelligence — are preparing to go public within months of each other, carrying a combined valuation of more than $3 trillion. All three could debut above $1 trillion. All three will reshape the composition of the world’s most important stock indexes. And all three are racing toward the public markets in the second half of 2026 with a ferocity that has Wall Street simultaneously salivating and bracing for impact.
The wildcard IPOs have arrived. Here is everything you need to know about the three companies that are about to change the investment landscape forever.
🚀 SpaceX — The Largest IPO in History, Launching June 12
There are companies that are exciting, and then there is SpaceX. Founded in 2002 by Elon Musk with the explicit goal of making humanity multiplanetary, SpaceX has spent two decades building what is now the most dominant space infrastructure company in history — and it is about to become a public stock.
SpaceX filed its S-1 with the SEC, targeting a Nasdaq listing under ticker SPCX on June 12, 2026, with the roadshow starting June 4 and pricing on June 11. The deal aims to raise roughly $75 billion at a $1.75 trillion valuation. If it prices at target, it will be the largest IPO in history — dwarfing Saudi Aramco’s $29.4 billion record by a factor of more than two. Tech Insider
The Business: Three Engines, One Machine
SpaceX operates three core business lines that share infrastructure but serve very different customers. Falcon launch services remain the cash cow on government and commercial contracts. Starlink is the consumer growth engine. Starship is the long-duration bet on heavy-lift reusability. Tech Insider
Starlink is the number that investors cannot stop talking about. SpaceX’s Satellite Internet and Infrastructure Services segment generated $11.4 billion in revenue in 2025, delivering $4.4 billion in operating income — 49.8% and 120.4% year-over-year increases respectively. Starlink subscribers crossed 10 million and the connectivity segment posted a $1.19 billion profit last quarter, still adding 750,000 to 1.5 million new subscribers every month. OpenAITech Insider
After the all-stock acquisition of Elon Musk’s xAI in February 2026, SpaceX is no longer just a rocket and satellite company. SpaceX’s acquisition of xAI and agreement with Anthropic positions it as an AI infrastructure provider — one that now owns rockets, satellites, a global broadband network, and an AI model. There is no comparable company anywhere on Earth. OpenAI
The Numbers
The S-1 discloses $18.67 billion in consolidated 2025 revenue with a $4.94 billion net loss, alongside adjusted EBITDA of $6.58 billion. The loss is almost entirely explained by Starship development costs — a capital-intensive bet on the future. The underlying business, stripped of Starship R&D, is already deeply profitable. SAP
The Risk
Elon Musk retains 85.1% voting control through a super-voting share class, so SPCX shareholders should expect minimal say over governance. You are not buying a vote. You are buying a stake in Musk’s vision. For many investors, that is exactly the point. For others, it is the only reason to hesitate. Tech Insider
If SpaceX is added to the Nasdaq 100 following its IPO, it would trigger mandatory purchases for every index-tracking fund in the world — a structural buying event that could push the stock significantly higher in the weeks following the debut, regardless of valuation debates. OpenAI
The Verdict: The most anticipated IPO of the decade. Prices June 11. Trades June 12. If you plan to participate, the window is two weeks away.
🤖 OpenAI — ChatGPT Goes Public at Nearly $1 Trillion
OpenAI confidentially filed its S-1 IPO prospectus with the SEC on Friday May 22, 2026, targeting a Q4 2026 public listing at a valuation between $852 billion and $1 trillion. Goldman Sachs and Morgan Stanley are leading the deal. A possible September debut is being discussed. The company that created ChatGPT — the fastest-growing consumer application in history — is finally going public. Windows Latest
The Business: The AI Platform That Won the Internet
OpenAI said ChatGPT has more than 900 million weekly active users and over 50 million subscribers, while its API processes more than 15 billion tokens per minute. Enterprise now represents more than 40% of revenue and is on track to reach parity with consumer revenue by the end of 2026. Medium
OpenAI is generating $2 billion in revenue per month. Its internal projections call for $2.5 billion in advertising revenue in 2026, rising to $11 billion in 2027 and $100 billion by 2030, contingent on the user base reaching 2.75 billion weekly users. For context: that user base projection would make ChatGPT the most-used application in human history, surpassing Google Search. Fordel Studios
The funding structure around the IPO is staggering. OpenAI closed a $122 billion funding round at an $852 billion post-money valuation, co-led by SoftBank alongside Andreessen Horowitz, D.E. Shaw Ventures, MGX, TPG, and T. Rowe Price. Amazon, NVIDIA, and Microsoft also participated, with Amazon committing $50 billion, NVIDIA $30 billion, and SoftBank $30 billion. When the world’s most important tech companies are competing to own a piece of you before your IPO, the public market demand will be extraordinary. Medium
The Numbers — And the Catch
OpenAI posted a 33% gross margin, constrained by inference costs that reached $8.4 billion in 2025 and are projected to rise to $14.1 billion in 2026. The company does not turn cash-flow positive until 2030. Fordel Studios
OpenAI is losing $1.22 for every $1 of revenue in Q1 2026. This is not a profitable business — yet. It is a land-grab of historic proportions, spending today to own the AI layer of the internet tomorrow. Amazon did the same thing for a decade. So did Uber. The question is whether OpenAI’s moat — 900 million weekly users, the most recognized AI brand on Earth, and a partnership web that spans every major tech company — is wide enough to justify the valuation before profitability arrives. Windows Latest
A renegotiated Microsoft deal caps OpenAI’s total revenue-share payments to Microsoft at $38 billion through 2030 — a significant structural improvement that removes one of the biggest overhangs on any future public listing. Fordel Studios
The Legal Clear
OpenAI’s IPO path has materially cleared following a May 2026 jury verdict finding Elon Musk’s lawsuit against the company time-barred, removing a significant legal overhang. The road to the public market has never been cleaner. Fordel Studios
The Verdict: The most consequential AI IPO in history. Targeting September–November 2026. The valuation will be debated furiously. The demand will be unlike anything seen since the dot-com era — only this time, the underlying business is real.
🧠 Anthropic — The Dark Horse That Just Became the Frontrunner
Of the three wildcard IPOs, Anthropic is the one that most investors are still underestimating. That is a mistake that is becoming more expensive by the week.
Anthropic’s valuation has grown roughly 15-fold in approximately 14 months. The company was valued at $61.5 billion in March 2025. By September it had reached $183 billion. In February 2026 it closed a $30 billion Series G at $380 billion post-money — the second-largest private financing round in history. Hashtag Legend
And then the revenue arrived.
The Revenue That Stopped People Mid-Sentence
Anthropic’s revenue trajectory is one of the most extraordinary in the history of enterprise software. The company ended 2024 at roughly $1 billion in annualised revenue. By end of 2025, $9 billion. By February 2026, $14 billion. By early April 2026, it crossed $30 billion in annualised revenue — representing approximately 1,400% year-over-year growth. NOL World
Bloomberg reported in May that Anthropic is in talks to raise at least $30 billion at a valuation exceeding $900 billion, which would make it the most valuable AI startup in the world, surpassing OpenAI’s $852 billion mark. NOL World
The company is in early talks with Goldman Sachs, JPMorgan, and Morgan Stanley about a potential IPO that could come as early as October 2026, with an expected raise exceeding $60 billion. Substack
The Strategic Moat
What makes Anthropic different from OpenAI is not just the technology — it is the enterprise trust story. While OpenAI won the consumer internet, Anthropic won the boardroom. Accounts spending more than $1 million annually doubled to more than 1,000 in less than two months. SAP, PwC, Zoom, and a growing roster of Fortune 500 companies have embedded Claude directly into their core workflows — not as a chatbot, but as an autonomous agent running mission-critical processes. The Korea Herald
On May 6, Anthropic said a new SpaceX compute agreement gives it access to more than 300 megawatts of capacity and over 220,000 NVIDIA GPUs within the month — the largest single compute expansion in the company’s history, ensuring it can meet the demand that is currently outrunning its capacity. The Korea Herald
Google owns 14% of Anthropic, a stake acquired through multiple investments totalling roughly $3 billion, and has reported $10.7 billion in net gains on those equity securities. Amazon, which has invested an estimated $8 billion and secured a position as Anthropic’s primary cloud and training partner, reported a $9.5 billion pretax gain tied to Anthropic’s rising valuation. When the two largest cloud platforms are both deeply invested in your success, you have structural support that no competitor can easily replicate. Substack
The IPO Setup
Both Anthropic and OpenAI are now racing toward public markets before the end of the year — the most closely watched rivalry narrative in years: two frontier AI companies, both targeting Q4 2026 public listings, both carrying valuations approaching or exceeding $1 trillion. Hashtag Legend
Anthropic’s shares were already trading on secondary markets at an implied $1 trillion valuation earlier this month — meaning the market has already priced the trillion-dollar debut before a single public share has been sold. Hashtag Legend
The Verdict: The quietest of the three wildcards, and possibly the most dangerous opportunity. Targeting October 2026. The company growing fastest, trusted most deeply in enterprise, and backed most strategically — going public right after the world has watched SpaceX and OpenAI debut. If the AI infrastructure thesis is right, Anthropic’s IPO may be the most important investment event of the decade.
🔮 The Big Picture: What Happens When $3 Trillion Hits the Market
Based on an assumed 5% free float applied to the mid-point of reported valuation estimates, the combined fundraising from SpaceX, OpenAI, and Anthropic would approach $200 billion — exceeding total US IPO proceeds from listings with market capitalisations above $50 million between 2022 and Q1 2026 combined. PwC
That is not a typo. Three companies going public in the space of four months could raise more than the entire US IPO market raised in the previous four years.
Goldman Sachs, JPMorgan, and Morgan Stanley are named advisers across multiple transactions. A full sweep of all three US listings within a single calendar year would represent the largest fee concentration in the history of equity capital markets. PwC
The implications cascade in every direction:
For index funds: SpaceX in the Nasdaq 100 alone would force trillions of dollars in mandatory reallocation. Every index ETF investor in the world becomes a SpaceX shareholder whether they intend to or not.
For existing AI stocks: Microsoft and SoftBank face a more ambiguous outcome — both hold stakes that will be marked-to-market upon listing, and the debut may prompt outflows from investors who have used either stock as an OpenAI proxy. PwC
For the broader market: Three of the most liquid, most discussed, most anticipated stocks in history will arrive simultaneously, absorbing capital from across the equity universe. Expect volatility, rotation, and some of the most dramatic single-day trading volumes ever recorded.
For the $1 trillion club: It will go from 14 members today to potentially 17 before 2026 is over — with all three new members being companies that did not exist as public entities twelve months ago.
The Bottom Line
The second half of 2026 is shaping up to be the most consequential period in stock market history since the dot-com era — and unlike 1999, the underlying businesses are real, the revenues are exploding, and the structural demand for what these companies build is not a speculative fever dream.
It is an AI-driven reorganization of the global economy, unfolding in real time, on a public exchange near you.
SpaceX launches June 12. OpenAI targets September. Anthropic aims for October. The $3 trillion IPO storm is not coming.
It is already here.
