Starcloud is a private company and has not filed a registration statement for an IPO; no reporting found as of the latest site review includes any Starcloud executive discussing a public listing. The Redmond, Washington-based orbital-data-center startup, founded in January 2024 as Lumen Orbit before rebranding in February 2025, raised a $170 million Series A in March 2026 at a $1.1 billion valuation, then closed a $250 million extension to that round on August 21, 2026 at a $2.3 billion valuation, with Nvidia joining as an investor, according to Reuters, SpaceNews, and the company's own announcement. In between, the company launched its first satellite, the roughly 60-kilogram Starcloud-1, into orbit aboard a SpaceX rideshare in November 2025, and in December 2025 it said it had trained AI researcher Andrej Karpathy's nanoGPT and run Google's Gemma model from space using an Nvidia H100 GPU, describing it as the first LLM training conducted in orbit, as reported by CNBC.

Key points
A rebrand, then two valuation jumps in under a year and a half
Starcloud started life in January 2024 as Lumen Orbit, founded in El Segundo, California by Philip Johnston, Adi Oltean, and Ezra Feilden through Y Combinator's Summer 2024 batch. The company raised a small $2.4 million round out of stealth in March 2024 and another $10 million in February 2025, the same month it rebranded from Lumen Orbit to Starcloud.
The bigger jumps came in 2026. Reuters reported that Starcloud closed a $170 million Series A on March 30, 2026 at a $1.1 billion valuation. Less than five months later, on August 21, 2026, the company announced a $250 million extension to that same Series A at a $2.3 billion valuation, with Nvidia joining the round alongside existing backers, according to SpaceNews and the company's own release.
What the money is actually funding
Starcloud's pitch is that data centers belong in orbit, where solar power runs continuously and there is no atmosphere or ground-based cooling infrastructure to fight. The company launched its first satellite, Starcloud-1, a roughly 60-kilogram spacecraft about the size of a small refrigerator, aboard a SpaceX rideshare mission in November 2025, according to Observer's interview with CEO Philip Johnston.
In December 2025, Starcloud said that hardware -- built around a single Nvidia H100 GPU -- had trained AI researcher Andrej Karpathy's nanoGPT model and run Google's Gemma model from orbit, a claim it framed as the first instance of LLM training conducted in space, as reported by CNBC.
No IPO conversation, and that's normal at this stage
Nothing in the reporting found as of the latest site review shows any Starcloud executive discussing a future public listing, and none of the funding announcements -- from the original $2.4 million stealth round through the $250 million Series A extension -- describe an IPO as a goal or a possibility. That is unremarkable for a company not yet three years old, still proving out a single-satellite proof of concept.
A public S-1 on SEC EDGAR, or a specific statement from Johnston or another Starcloud executive, would be the first verifiable sign that a listing process has begun. Neither exists as of the latest site review, and any specific 'Starcloud IPO date' circulating online is speculation with nothing behind it yet.

Search intent
Searches like 'When Will Starcloud IPO? Its Valuation Doubled in 5 Months. It Isn't Even 3 Years Old.' are research questions: what a filing or a company statement confirms, what has only been reported, and what is still unknown.
What counts as a listing step
For an IPO, the primary record is a registration statement filed with the securities regulator of the listing market, such as an S-1 or F-1 on SEC EDGAR for a US listing. Funding rounds, valuations and secondary-market prices are context, not listing steps.
Segmara role
Segmara is an independent research site. It does not sell, broker, or arrange share purchases, and nothing on this page is investment advice.
How a company reaches a US listing
The SEC filing trail
DraftThe company can first submit a draft registration statement (DRS) for confidential SEC review.
S-1 or F-1The registration statement goes public on SEC EDGAR: Form S-1, or Form F-1 for many foreign companies. A company that used a draft must file publicly at least 15 days before its roadshow.
AmendmentsS-1/A or F-1/A amendments answer SEC comments, and one of them adds the expected price range.
PricingOnce the SEC declares the registration effective, the company sets the price with its underwriters and files the final prospectus, usually a 424B4.
First tradeThe shares start trading on the exchange named in the prospectus, such as Nasdaq or the NYSE.
Segmara Pro checks SEC EDGAR for Starcloud filings every weekday and posts an alert in the members forum when one of these public filings appears. You can also check yourself with EDGAR full-text search.
No S-1 or F-1 exists for Starcloud on SEC EDGAR as of the latest site review, and no Starcloud executive has publicly discussed a future IPO in any reporting found -- the company is not yet three years old, having been founded as Lumen Orbit in January 2024.
Starcloud's valuation roughly doubled in under five months: a $170 million Series A in March 2026 valued it at $1.1 billion, and a $250 million extension to that same round on August 21, 2026 pushed the valuation to $2.3 billion, with Nvidia joining as a new investor, per Reuters and SpaceNews.
Starcloud launched its first satellite, the 60-kilogram Starcloud-1, into low Earth orbit on a SpaceX rideshare in November 2025, and in December 2025 reported training Andrej Karpathy's nanoGPT and running Google's Gemma model from space on an Nvidia H100 GPU -- what it called the first LLM training conducted in orbit, per CNBC.
Risk notes
Rumor risk: unofficial dates, valuations, or funding details circulating on social media or forums are frequently wrong or outdated and should not be treated as confirmation of anything.
Illiquidity risk: any private-market interest, indicative marks, or pre-IPO share arrangements in a company that has not filed to go public can be difficult to exit and may not reflect a tradable price.
Timing risk: a company can pause, restart, or abandon IPO preparation at any stage, including after a confidential draft filing, so no step before an effective registration statement guarantees a listing will occur.
Segmara Pro: a weekly IPO brief plus SEC filing alerts for 60+ companies, including Starcloud, from automated EDGAR checks every weekday, posted in the members forum; 7-day free trial, then $15 a month (plus any applicable tax). Research only, no share sales.

Yes. The free Starcloud tracker sends indicative marks by email, with no card and no documents. Segmara does not sell, broker, or arrange share purchases.
Why was this market historically hard for retail investors to reach?

What is the easiest next step?
Open the free Starcloud tracker first, email only. The IPO calendar is free, and Segmara Pro adds a weekly IPO brief.
Has Starcloud confirmed an IPO date?
No. As of the latest site review, no S-1 or F-1 has been filed, and no reporting found includes any Starcloud executive discussing a future public listing. The company is still in its early, funding-round-driven growth phase.
What is Starcloud worth?
The most recent verified figure is a $2.3 billion valuation, set by a $250 million extension to its Series A round that closed August 21, 2026, according to SpaceNews and the company's own announcement. That is roughly double the $1.1 billion valuation set by the original $170 million Series A in March 2026.
What has Starcloud actually launched?
One satellite so far: Starcloud-1, a roughly 60-kilogram spacecraft the company launched via a SpaceX rideshare mission in November 2025. In December 2025, Starcloud said it used that hardware, built around an Nvidia H100 GPU, to train Andrej Karpathy's nanoGPT and run Google's Gemma model in orbit, as reported by CNBC.
Can I buy Starcloud shares before an IPO?
Not through a public exchange. Starcloud is a private company, and any private-share offer you encounter should be verified independently before you rely on it. Segmara does not sell, broker, or arrange purchases of Starcloud shares.
