SpaceX June 12 · Anthropic October · OpenAI Q4 — The Real Weight of 2026's IPO Pipeline
SpaceX targets a $1.75T June listing, Anthropic eyes October at $900B, OpenAI Q4 remains uncertain. Cerebras's 68% first-day surge was just the warm-up. 2026 IPO proceeds stand at $28.4B — and counting.
- SpaceX (June 12, $1.75T), Anthropic (October, $900B), and OpenAI (Q4, uncertain) are queued behind Cerebras's 68% debut — and could push 2026 U.S
- IPO proceeds far beyond the current $28.4B
- Renaissance Capital notes the software sector still hasn't cleared market validation, with AI infrastructure, energy, and space driving this year's IPO successes
Cerebras (CBRS) debuted this week with a 68% first-day surge, claiming the title of 2026's largest IPO. But this was just the warm-up.
Renaissance Capital chief strategist Matthew Kennedy framed it this way: "This year's IPO class is characterized by early-stage companies making big bets on large markets." Total U.S. IPO proceeds for 2026 stand at $28.4 billion. If SpaceX, Anthropic, and OpenAI all list this year, that number moves into an entirely different dimension.
SpaceX — June 12, Target Valuation $1.75 Trillion
According to the WSJ, SpaceX is planning to list on June 12. The target valuation is $1.75 trillion, with a fundraising target of $75 billion. A definitive offering price and valuation have not yet been disclosed.
$1.75 trillion is roughly half of Nvidia's current market cap (~$3.6T) but more than a third of Alphabet's (~$4.8T). SpaceX is one of the rare space companies already generating profit through rocket launches, Starlink, and military contracts. Analysts argue that Starlink alone could support a multi-trillion-dollar valuation thesis. SpaceX's listing could produce a dual effect: compressing the proxy premium attached to Rocket Lab (RKLB) while drawing more institutional capital into the space sector overall.
Anthropic — October Target, $900B Valuation
According to the Financial Times, Claude maker Anthropic is targeting an IPO as early as October, with a $30 billion fundraising target at a $900 billion valuation. No formal SEC filing has been submitted yet.
$900 billion exceeds OpenAI's most recent funding valuation of $852 billion. Google and Amazon have each invested billions in Anthropic. As the foundation model powering countless AI services, Anthropic's listing is expected to attract significant market attention.
OpenAI — Q4 Possibility, Highest Uncertainty
OpenAI could compete with Anthropic in the Q4 IPO window, but carries the most uncertainty. According to the WSJ, the company has fallen short of its own revenue targets. CFO Sarah Friar has cautioned that OpenAI is not yet ready to go public. Litigation with Elon Musk is ongoing. While a recent round raised $122 billion — confirming an $852 billion valuation — the IPO timeline remains open.
Two More Companies Debuted the Same Week
Cerebras wasn't the only newcomer this week. On the same day, Blackstone launched Blackstone Digital Infrastructure Trust (BXDC), aimed at acquiring AI data center assets. It raised $1.75 billion but its stock fell — it currently holds no assets. Earlier, Texas-based geothermal energy company Fervo Energy (FRVO) raised $1.89 billion, claiming the title of the largest renewable energy IPO in history.
Software Is Still Struggling
Kennedy's diagnosis is sharp: "If you're not at the heart of the AI boom, you need to show you're resistant to the AI bust. The software sector hasn't cleared that bar yet." This year's IPO successes are being driven by three real-asset themes — AI infrastructure, energy, and space. Pure-play software companies are still waiting for market validation.
Frequently Asked Questions
How does SpaceX's IPO affect Rocket Lab (RKLB)?
It cuts both ways. If SpaceX's listing draws more institutional capital into the space sector, Rocket Lab benefits. But once investors can buy SpaceX directly, the proxy premium attached to RKLB may compress.
Is Anthropic's $900B valuation reasonable?
With annualized revenue exceeding $30 billion, that implies a price-to-sales ratio of around 30x — far lower than Cerebras's 200x+ PSR. Google and Amazon's strategic investments provide structural support for the valuation.
Will OpenAI actually IPO in 2026?
The CFO explicitly flagged the company isn't ready, a revenue shortfall was reported, and Musk litigation is ongoing. Market consensus is that OpenAI is less likely to list in 2026 than Anthropic.
How can Korean investors access these pre-IPO names?
Until SpaceX, Anthropic, and OpenAI list, the only option is indirect exposure through vehicles like DXYZ (Destiny Tech100), which holds stakes in pre-IPO companies. After listing, each can be purchased directly by ticker.
