SpaceX just did something no company has ever done: raised $75 billion in a single IPO, pricing 555.6 million shares at $135 each, landing a market cap of $1.77 trillion. That's not a typo. It's the biggest initial public offering in history — by a margin that makes most tech IPOs look like seed rounds.

The numbers are almost absurd. BlackRock put in an order for at least $5 billion worth of shares. A single family office requested over $1 billion. Retail investors collectively placed over $100 billion in orders, and they're expected to get at least 20% of the allocation. Founders Fund's ~3% stake is now worth $50 billion-plus — they invested $600 million over the years. Andreessen Horowitz is looking at the biggest return in its history, with a $10 billion-plus stake.

But here's where it gets interesting for AI. Some investors are pushing back on the valuation. SpaceX lost $4.3 billion on $4.7 billion in revenue in Q1 alone. Questions are being raised about space data centers — the idea that orbital computing could power AI workloads. It's an intriguing concept, but the financials don't yet back up the hype.

Meanwhile, the same day this IPO was pricing, Jeff Bezos' Prometheus — which is building AI models for physical tasks — raised a $12 billion Series B at a $41 billion valuation, following a $6.2 billion Series A. That's $18 billion raised in a month for AI that interacts with the physical world. Not bad for a "side project" from the Amazon founder.

The pattern is clear: capital is flowing aggressively toward AI infrastructure, whether it's orbital computing or robotics that can work in real environments. SpaceX's IPO gives Elon Musk the war chest to fund exactly that kind of expansion. The question isn't whether AI will need more compute — it's whether the companies raising these valuations can deliver returns.

For now, SpaceX has the momentum. The biggest IPO ever is also the most oversubscribed. But at $1.77 trillion, the market is pricing in a lot of future that hasn't arrived yet.
