Friday was one of those days where the AI business stopped pretending it was just about models and started showing you the money. Three things landed at once, and they all point the same direction.
SpaceX went public. More businesses are now paying for Claude than for ChatGPT. And Anthropic got caught surprising its own partners. Let me walk you through it.
SpaceX Went Public and the AI IPO Door Swung Open
SpaceX closed its first day on the Nasdaq up about 25 percent. Shares priced at $135, opened at $150, and finished at $168.70. That puts the company around a $1.77 trillion market cap, which makes it the biggest IPO anybody has ever done.
The xAI deal from February folded Grok, the X network, and the Colossus data centers into the same public company. So this is not just rockets. It is an AI infrastructure bet wearing a SpaceX jersey.
Here is why it matters. Anthropic and OpenAI are both lining up their own listings, and they have been waiting to see if Wall Street would actually pay premium prices for a money-losing AI infrastructure name. A 25 percent pop is the answer. Not a moonshot, not a faceplant. Just a clean, orderly debut.
My take: this was the green light everybody was watching for. A calm 25 percent is way better news for Anthropic and OpenAI than a 90 percent fireworks show, because the fireworks version is the one that screams bubble. The door is open now. Expect the rest of them to walk through it before the year is out.
More Businesses Are Paying for Claude Than ChatGPT
The Ramp AI Index tracks what companies actually put on their corporate cards. In April, Anthropic climbed to 34.4 percent of tracked businesses while OpenAI slipped to 32.3 percent. That is the first time Claude has ever been ahead on business adoption.
Look at the run. Anthropic went from basically zero in 2023 to under 8 percent in early 2025 to over 34 percent now. The engine behind a lot of that is Claude Code, which Ramp says is the fastest growing product the company has ever shipped. One estimate had Claude Code writing 4 percent of all public GitHub commits, double what it was a month earlier.
Now, before anybody spikes the ball, a separate IDC survey says only 19 percent of organizations report heavy Claude use, still behind OpenAI and Google. The two reports measure different things. Ramp counts who is paying. IDC counts how deep people are going. Both can be true at the same time.
My take: paying for a tool and living in a tool are not the same thing, and the gap between those two numbers is the whole ballgame. Anthropic is winning the new signups. Whether folks stick around depends on what happens to pricing, which brings me to the part that worries me.
Anthropic Keeps Surprising Its Own Partners
The Information ran a piece this week on how Anthropic has been launching products that compete with its own partners without much of a heads up. The example that stings: weeks before rolling out Claude Design back in April, the company asked Figma and Canva to be launch partners. Claude Design competes straight at what those two sell.
This lines up with the billing change from earlier in the spring, when Anthropic moved enterprise customers off flat per-seat pricing onto usage-based billing with little warning. One compliance shop figured that could double or triple the bill for heavy users.
Why it matters: Anthropic is trying to win big multi-year enterprise contracts right before an IPO. The thing that kills those deals is a buyer worrying the vendor will turn around and compete with them or change the price on a Tuesday. Trust is not a soft issue here. It is a revenue durability issue, and the people reading the S-1 will notice.
My take: moving fast is fine. Moving fast on the people who agreed to stand on stage with you is how you end up with a reputation that costs more than any single product launch earns back. Anthropic is the adoption leader right now. Staying there is going to take treating partners like partners, not like a runway. Ship great stuff, sure, but quit blindsiding the folks who bet on you.
That is the week. Big money got real, Claude took the lead, and the fine print got interesting. See y'all tomorrow.
