Something is happening over the next few months that has never happened before in the history of public markets, and I want to make sure you understand it before everyone on financial TV starts shouting about it.
Three of the most valuable private companies on Earth are all heading for the public market at the same time. Yesterday, June 1, Anthropic confidentially filed its IPO paperwork at a $965 billion valuation. SpaceX kicks off its roadshow as early as June 4 and prices around June 11, targeting somewhere near $1.8 trillion. OpenAI is lining up for September at what could be a trillion-dollar debut. Add it up and you're looking at more than $3 trillion of value hitting public markets in a matter of months — the most concentrated wave of mega-IPOs the world has ever seen.
This is a huge deal for your money whether you plan to buy a single share or not. So let me walk you through what's actually going on, who's really winning, and — this is the part most coverage skips — exactly where the traps are hiding.
The three giants, side by side
Let me lay these out next to each other, because seeing them together tells you more than any one of them alone.
| Company | Target valuation | Timing | What it really sells | The catch |
|---|---|---|---|---|
| SpaceX | ~$1.75-2T | Roadshow June 4, price ~June 11 | Starlink (61% of revenue) | AI division lost $6.35B last year |
| Anthropic | ~$965B | Filed June 1, listing this fall | Claude, Claude Code, enterprise | Only just turned its first profit |
| OpenAI | ~$1T (est.) | Targeting September | ChatGPT, enterprise, ads | Still burning billions |
Notice something? The headline you'll hear is "AI IPO wave." But the biggest of the three, SpaceX, isn't really an AI story at all — its profit engine is Starlink, the satellite internet business, which brought in $11.39 billion last year and was the only division actually making money. The rocket unit lost $657 million and the AI division lost a staggering $6.35 billion. So when someone tells you SpaceX is a $2 trillion "AI play," gently correct them: it's a satellite internet company with a rocket business attached and an AI moonshot burning cash on the side.
That distinction matters, because it tells you the market is so hungry for these names that it's bundling very different businesses under one exciting label. And that's exactly the environment where you can get hurt if you're not paying attention.
Why all three are rushing the door at once
You might wonder why these companies, which spent years happily private, are suddenly sprinting to go public in the same quarter. The honest answer is a mix of opportunity and pressure.
The opportunity: public-market appetite for AI is at a peak, and these companies can raise enormous sums at valuations that simply weren't available a year ago. Anthropic's number is the clearest example — it closed a $65 billion round at $965 billion just days before filing, after its revenue run rate exploded from $10 billion to $47 billion in roughly a year. When the market will hand you that kind of valuation, you take it.
The pressure: early investors and employees have been waiting a long time for a payday, and going public is how they finally cash out. I covered the Anthropic raise and its leap past OpenAI when it was still a private story, and the broader trillion-dollar AI race that set this all up. The IPOs are the next logical chapter: the private rounds got so large that the only buyers left big enough to absorb more are the public markets — meaning you and your retirement fund.
That's not a knock on the companies. It's just important you understand the mechanics, because they shape who wins and who loses.
Here's where you could get burned
I promised you the part most coverage skips, so here it is — read this section twice if you're tempted to buy any of these.
The retail allocation is unusually large, and that should make you curious, not just excited. SpaceX is reportedly reserving up to 30% of its offering for retail investors — roughly three times the normal 5-10%. OpenAI's CFO called retail participation "good hygiene." That sounds generous and democratic. But ask yourself: why are these the most retail-friendly mega-IPOs in history? One read is genuine access. Another, more cynical read is that there's so much insider stock to offload that they need a bigger pool of buyers. Both can be true at once. Just go in with eyes open.
The insiders are already selling. This is the signal I'd weight most heavily. More than 600 current and former OpenAI employees have reportedly sold around $6.6 billion in stock on the secondary market ahead of the IPO. When the people who know the company best are taking money off the table before you can even buy in, that's worth pausing on. It doesn't mean the company is bad — it means the people closest to it are managing their risk, and you should manage yours.
Lockups and small floats can whipsaw the price. Here's the mechanic that catches new investors every time. Companies often release only a small slice of shares at IPO (a "small float"), which can make the price pop on day one. Then, months later, the lockup expires and insiders are suddenly free to sell — and the price can drop hard. Figma's IPO was a textbook case: retail piled in on the opening pop while insiders prepared to sell at the first lockup trigger. If you don't know when the lockups expire, you're trading blind against people who do.
I'm not telling you to avoid these — I'm telling you to understand the machine before you put your money in it. That single habit separates people who do well in IPOs from people who become the exit liquidity.
The smarter way most people miss
Here's something I genuinely want you to consider, because it's the move the pros use and almost nobody talks about: you can often get exposure to these companies without touching the IPO at all.
Every one of these giants has public "proxies" you can already buy. Anthropic's biggest backers and partners are Amazon, Microsoft, and Nvidia — all public, all benefiting directly as Claude grows. OpenAI's success flows straight to Microsoft, its cloud and equity partner. SpaceX has public adjacents like Rocket Lab and AST SpaceMobile in the orbital economy. When you buy the proxy, you skip the IPO-day frenzy, the small-float pop, and the lockup cliff entirely.
And if picking individual proxies feels like too much, this is exactly what AI-focused funds are built for. I walked through that approach in the guide to AI ETFs — you get a basket of the whole theme, so no single overpriced IPO can wreck you. For the bigger picture of how these companies are valued in the first place, my breakdown of AI startup valuations will help you judge whether a trillion-dollar price tag is visionary or delusional, and the wider IPO pipeline guide maps who else is lining up behind these three.
What I'd actually do
So if you're sitting there wondering whether to get involved, here's the honest playbook I'd follow.
First, decide what you're actually buying. SpaceX is a satellite-internet-plus-rockets bet with an AI option attached — not a pure AI play. Anthropic and OpenAI are pure frontier-AI bets, and OpenAI's growth has been historic, but both are still proving they can turn that growth into durable profit. Know which story you're buying before you buy it.
Second, don't chase the day-one pop. The single most common way regular investors lose on hot IPOs is buying into the opening excitement and holding through the lockup cliff. If you want in, waiting weeks or months for the hype and the insider selling to settle is usually the smarter entry.
Third, size it like the risk it is. These are exciting, volatile, richly-priced names. Whatever you'd put in, that's money you should be genuinely okay losing a chunk of. Exciting and safe are not the same word.
The honest take
What's happening this summer is genuinely historic — over $3 trillion of the most talked-about companies on the planet opening up to ordinary investors for the first time, with retail access bigger than any IPOs before them. That's real, and the opportunity is real. I'm not here to rain on it.
But I'd be doing you a disservice if I let you walk in thinking this is free money. The same features that make these IPOs exciting — the scale, the hype, the unusually large retail allocation — are exactly the features that can leave latecomers holding the bag when the lockups expire and the insiders, who've already started selling, finish the job. The companies are extraordinary. Whether the price you pay on IPO day is a good deal is an entirely separate question, and only you can answer it.
So before you put a dollar into any of these, ask yourself the one question this whole frenzy comes down to: are you buying because you understand the business and the price — or because everyone else is, and you're afraid of missing out? Get that answer right, and you'll do fine no matter which of these giants you back.
