SpaceX started trading on the Nasdaq today under the ticker SPCX, and for an AI newsletter this is bigger than a rocket story. When SpaceX absorbed xAI in February in an all-stock merger, Elon Musk's AI lab, the Grok chatbot, the X platform, and the Colossus supercomputer all became part of SpaceX. So when the opening bell rang this morning, the largest IPO in history was also, by default, the largest AI company ever to go public. The stock priced at $135, opened at $150 for an 11% pop, and closed at $161, up 19% on the day. That values the combined company at roughly $1.77 trillion, surpassing Saudi Aramco's 2019 listing as the biggest market debut ever recorded. Gwynne Shotwell rang the opening bell at the Nasdaq in Times Square while a second ceremony ran simultaneously at Starbase in Texas. For the first time, public investors can buy a frontier AI lab directly. Not exposure through Nvidia's chips or Microsoft's stake in OpenAI. The actual lab, the actual model, the actual supercomputer, trading as a stock. That has never happened before, and it just became the climax of the AI IPO wave we have tracked all year.

When you buy SPCX, you are buying three businesses fused into one instrument, and the AI piece is the part that makes this newsletter-worthy.

Grok and xAI. The February merger folded xAI directly into SpaceX at a $250 billion valuation. That means the Grok large language model, which competes with Claude, Gemini, and ChatGPT, is now a publicly traded asset. Anyone with a brokerage account owns a slice of a frontier model. This is genuinely new. Until today, every pure-play frontier lab, OpenAI, Anthropic, xAI, was private, and the only way to bet on them was indirectly.

Colossus, the supercomputer. xAI built Colossus in Memphis, described in filings as the largest coherent AI training cluster on earth, a roughly 2-gigawatt computing complex. SpaceX now owns it, and here is the twist that ties directly to stories we have covered: SpaceX is renting Colossus out to its own competitors. Anthropic pays $1.25 billion a month for Colossus 1 capacity through 2029. Google signed a separate deal at $920 million a month. Combined, those two contracts are worth roughly $26 billion a year in compute revenue, from two of the best-funded AI companies in the world. So a chunk of what you are buying in SPCX is the picks-and-shovels business underneath Anthropic and Google's AI.

The X platform and Starlink. You also get the X social network and, the actual profit engine, Starlink satellite internet, which did $11.4 billion in 2025 revenue at a 39% operating margin. Starlink is what makes the whole thing financially work.

So the AI lab rides public on the back of a profitable satellite business. That structure is the entire story.

Step back and look at what 2026 has actually been. We have tracked this arc all year, and today is the summit.

Cerebras went public in May, the AI chipmaker, and nearly doubled on debut. Anthropic filed its confidential S-1 on June 1 at a $965 billion valuation. OpenAI filed its own on June 8 at $852 billion. And today SpaceX, carrying xAI inside it, became the first of the group to actually trade, at $1.77 trillion, the largest IPO ever. The private AI boom has officially started converting into public-market reality, and it is happening in a matter of weeks.

The detail that matters for the labs still waiting in line: bankers told both Anthropic and OpenAI there is an early-mover advantage to being the first AI lab to list, because the first one sets the template for how investors value the entire category. SpaceX just beat them to it. Every analyst pricing Anthropic and OpenAI now has a public comparable to point to. The way SPCX trades over the next weeks will quietly shape what Anthropic and OpenAI can command when they list this fall.

For anyone who reads financial news, here is the part the hype skips, because the AI piece cuts both ways.

The AI segment is losing enormous money. xAI posted a $2.47 billion operating loss in Q1 2026 alone. Across 2025, the AI segment generated $3.2 billion in revenue against a $6.4 billion operating loss. Without the xAI merger, SpaceX would have posted a profit in 2024. With it, the combined company posted a $4.9 billion net loss in 2025. Grok is burning cash and facing sharper competition from Claude, Gemini, and ChatGPT, exactly the models whose makers are now renting xAI's own supercomputer.

The bull case is that the compute deals change the math. Those Anthropic and Google contracts turn Colossus from a cost center into roughly $26 billion of annualized revenue, and SpaceX plans to push further into commercial orbital data centers by 2028. The bear case is straightforward: at $1.77 trillion the combined company trades at a punishing multiple of sales, Grok has not won its market, and Wall Street price targets range wildly, from $190 on the high end to $63 on the low end. That spread tells you nobody actually agrees what this is worth.

This is information, not advice. We do not tell you whether to buy. But if you are going to own a piece of a frontier AI lab for the first time in history, you should know you are buying a cash-burning AI business wrapped around a profitable satellite company, at the most expensive valuation a tech IPO has ever carried.

SpaceX began trading on the Nasdaq today as SPCX, pricing at $135, opening at $150, and closing at $161, up 19%, at a roughly $1.77 trillion valuation, the largest IPO in history. Because SpaceX absorbed xAI in February, this is also the largest AI company ever to go public: buying SPCX means owning the Grok model, the Colossus supercomputer, and the X platform alongside Starlink. Colossus is already generating about $26 billion a year renting compute to Anthropic and Google, the very rivals Grok competes with. It is the peak of the 2026 AI IPO wave, after Cerebras went public in May and Anthropic and OpenAI filed their S-1s this month, and SpaceX listing first gives both of them a public benchmark before their own fall debuts. The honest caveat: the AI segment is losing billions, Grok has not won its market, and the valuation is the richest a tech IPO has ever carried, with analyst targets ranging from $63 to $190. For the first time, a frontier AI lab trades as a stock. Whether that is a milestone or a bubble marker is the trillion-dollar question, and today the whole market just placed its bet.
