Celestial AI Stock: Why There Is No Ticker to Buy
If you don’t want to read the whole guide or have difficulty reading, you can listen to this guide instead.
If you came here to buy celestial ai stock, here is the short answer first. There is no Celestial AI stock on any exchange, there is no ticker symbol, and there never was.
The company stayed private from its founding in 2020 until Marvell Technology acquired it. The deal closed on February 2, 2026, so Celestial AI now sits inside Marvell, which trades on the Nasdaq as MRVL.
At AI Holic we track AI companies and their funding stories. Below is the full picture: what Celestial built, how its value climbed, how the deal was structured, and what happened to the shares private platforms used to list.
The Short Answer: No Public Stock, and No IPO Coming
Celestial AI never listed on a stock exchange. While it was independent, its shares changed hands only in private funding rounds and on pre-IPO platforms that serve accredited investors.
Some of those platforms still show a symbol next to the company name. EquityZen lists it as CEEA, but EquityZen itself notes that it created that symbol for use on its own platform. It is a label, not a market ticker.
With the Marvell deal closed, an IPO is off the table for good. The company no longer exists as an independent business, so there is no listing to wait for.
What Celestial AI Actually Does
Celestial AI builds interconnect technology for AI data centers. Its platform, called Photonic Fabric, moves data with light instead of electric signals over copper wire.
The problem it attacks is simple to state. AI clusters link thousands of processors and memory chips, and the links between them eat power and create heat. A link built on silicon photonics carries data as light, which aims to give more bandwidth for less power.
The company was founded in 2020 by David Lazovsky and Preet Virk and is based in Santa Clara, California. Its backers treated the interconnect problem as one of the core bottlenecks in AI hardware, and the funding rounds below show how quickly that view spread.
The Funding Run: Seed to a $2.5 Billion Valuation
Celestial raised about $590 million in total before the acquisition. Tracker totals differ slightly by how they group each round, with Forge Global at $588.62 million and Notice at $593.87 million.
| Round | Date | Raised | Valuation after the round |
|---|---|---|---|
| Series A | February 2022 | $55.75 million | $172.97 million |
| Series B | June 2023 | $100 million | $368.65 million |
| Series C | March 2024 | $175 million | $1.22 billion |
| Series C-1 | March 2025 | $250 million | $2.5 billion |
The final private round, Series C-1 in March 2025, priced shares at $17.43 and valued the company at $2.5 billion. Its investors included Tiger Global, Fidelity, BlackRock and Temasek, along with strategic backers such as AMD Ventures, Koch Disruptive Technologies, Porsche Automobil and Samsung Catalyst Fund.
That $17.43 figure is the last private price the trackers recorded. It is a historical marker now, not a price you can act on.
The Marvell Deal, Term by Term
Marvell announced a definitive agreement to acquire Celestial AI on December 2, 2025. The upfront value was about $3.25 billion, split between $1.0 billion in cash and about 27.2 million Marvell shares worth about $2.25 billion at signing.
On top of that sits an earnout of up to about $2.25 billion, which would take the total to about $5.5 billion. It pays out against revenue milestones measured by the end of Marvell’s fiscal year 2029: the first third at $500 million in cumulative revenue, and the full amount above $2.0 billion.
The deal closed on February 2, 2026. From that date, Celestial AI’s shares stopped trading on secondary platforms, and the trackers stopped pricing them.
What Happened to the Pre-IPO Shares
Holders of Celestial shares received the deal consideration instead: a mix of cash and Marvell shares under the acquisition terms. The private shares themselves ceased to exist as a separate asset.
This is why some pages you will find are now wrong. A few pre-IPO platforms still carry older copy inviting visitors to invest in Celestial AI, written before the acquisition closed. The company those pages describe no longer exists in that form.
If a site offers to sell you Celestial AI shares today, treat it as out of date at best. There is no private market left for this stock.
The Only Public Route: Marvell (MRVL)
For anyone still searching for celestial ai stock, the only public route runs through the buyer. Celestial AI’s technology now sits inside Marvell, a large data infrastructure chip company, and Marvell shares trade on the Nasdaq as MRVL.
That exposure is diluted by design. Celestial is one part of a much bigger company, so Marvell’s share price moves on Marvell’s overall results, not on Celestial’s progress alone.
This article is information about a company and a deal, not financial advice. Whether MRVL or any other stock fits you is a decision for you and, ideally, a licensed adviser who knows your situation.
