Anthropic Series H: $965B Valuation, Past OpenAI's $852B

[Alex]: Hey everyone, welcome back to the Nerd Level Tech AI Cast—the show where GPUs are hot, valuations are hotter, and we’re all just trying to keep our RAM from overheating. I’m Alex.

[Jamie]: And I’m Jamie! Alex, today’s episode is basically the Super Bowl for AI startup nerds—Anthropic just dropped a 65 billion dollar Series H round, landing them a wild 965 billion valuation. That’s right, folks, they’ve leapfrogged OpenAI! I feel like I should be tossing confetti or something.

[Alex]: Hold onto that confetti—if we keep seeing numbers like this, we’ll need ticker tape parades every week. But yeah, this is huge: for the first time, Anthropic’s valued *higher* than OpenAI, at least in a primary funding round. That’s a $113 billion edge over OpenAI’s last round back in March.

[Jamie]: Okay, so, quick question for the “wait, what just happened?” crowd: Anthropic just raised $65 billion—who’s writing these checks? Is this just Jeff Bezos emptying his piggy bank?

[Alex]: [laughs] Not quite, though Amazon did toss in $5 billion of previously committed “hyperscaler” capital. The main leads were Altimeter Capital, Dragoneer, Greenoaks, Sequoia—you know, the usual suspects when tech FOMO strikes. Then there’s a shopping list of big co-leads: Capital Group, Coatue, D1, GIC, ICONIQ, XN… honestly, it reads like a who’s-who of institutional investors.

[Jamie]: [PAUSE] And that $15 billion in “hyperscaler” capital—what’s that about? Is that just a fancy way of saying “cloud money”?

[Alex]: Pretty much. Hyperscalers are your cloud giants—think Amazon, Google, Microsoft. Anthropic’s round bundled in earlier commitments from these players, so the headline number is a bit of new cash, a bit of previously pledged cloud credit. It’s like when you finally redeem all those Starbucks points you’ve been hoarding—except, you know, for supercomputers.

[Jamie]: I’d take a venti GPU, please. [laughs] So what justifies this sky-high valuation? Is Anthropic suddenly printing money?

[Alex]: Well, actually… kinda, yeah. Their disclosed run-rate revenue hit $47 billion just this month. That’s up from $14 billion only three months ago at their Series G. For context, OpenAI’s last public run rate was about $24 billion annualized. So Anthropic’s basically pulled a “hold my beer” and doubled it.

[Jamie]: [PAUSE, whistling] Wait, so Anthropic’s revenue almost tripled in, like, a quarter? What are they selling, gold-plated AIs?

[Alex]: [smirks] Close—Claude Opus 4.8 just launched, which is their flagship model. And on the same day as the funding announcement, no less. It’s like Apple launching a new iPhone and announcing they just bought Google, all in one keynote.

[Jamie]: I did see the “Opus 4.8” headlines. What’s so special about it?

[Alex]: Bunch of things—88.6 on SWE-bench Verified, 69.2 on SWE-bench Pro, and a 3x cheaper fast mode. But honestly, the real magic’s in the infrastructure deals. Anthropic signed massive compute contracts: 5 gigawatts with AWS, another 5 with GoogleBroadcom for next-gen TPUs, and—get this—full access to SpaceX’s Colossus 1 supercomputer.

[Jamie]: [PAUSE] Wait, SpaceX? As in, rockets and Mars? They’re in the AI game now too?

[Alex]: Oh yeah. Colossus 1 in Memphis—over 220,000 NVIDIA GPUs, just sitting there like the world’s fanciest gaming rig. It was built for xAI, but now Anthropic’s got dibs. There’s even a clause: if Anthropic’s models go rogue, SpaceX can yank access. The world’s first “Skynet Clause,” I guess.

[Jamie]: [laughs] “I’m sorry, Dave, I can’t let you train that model.” So, is Anthropic just hoarding all the GPUs? What’s the play here?

[Alex]: It’s an arms race for compute. The more access you have, the bigger and better models you can train. Anthropic’s now the only AI lab publicly running on AWS, Google Cloud, Microsoft Azure, *and* SpaceX’s GPU farm. It’s like being the only kid on the block with every console—and a few that haven’t even launched yet.

[Jamie]: [PAUSE] So, with all this heat, are they going public soon? Should I be buying Anthropic socks in anticipation of an IPO?

[Alex]: [chuckles] No Anthropic ticker or S-1 filing yet as of May 28th. But they’ve lawyering up with Wilson Sonsini, and the investor list is loaded with IPO-friendly institutions—Fidelity, T. Rowe Price, Baillie Gifford, GIC, Temasek… you get the idea. Rumor mill says October 2026 is the target window, with Goldman, JPMorgan, and Morgan Stanley circling.

[Jamie]: So, basically, it’s “IPO soon-ish, but don’t camp out for the roadshow just yet.”

[Alex]: Exactly. Think of this Series H as a pre-IPO warmup—recapitalizing, locking in supply chain partners like Micron and Samsung. Gotta make sure nobody runs out of memory chips when you’re printing $47 billion a year.

[Jamie]: [PAUSE] This is all wild. But what’s the bottom line for the AI arms race? Is Anthropic going to stay on top, or is OpenAI just biding their time?

[Alex]: Great question. The lead is slim—about 13%. Both are raising at historic levels and scaling like crazy. OpenAI’s got a confidential S-1 in, so when they go public, the rankings could flip again. But for now, Anthropic holds the crown as the world’s most valuable AI startup, at least in the primary market.

[Jamie]: So, today’s lesson: in 2026, AI startups raise money so fast, even their models can’t keep up. And if you want to rule the world, better start collecting GPUs and strategic chip partners like Pokémon cards.

[Alex]: [laughs] Gotta catch ‘em all, indeed. That’s all for today’s episode of Nerd Level Tech AI Cast! If you enjoyed the show, hit that subscribe button, leave us a review, and don’t forget to power-cycle your brain before next week.
