# What Is Castelion’s Valuation in 2026? $13B After $1B

> Castelion closed a $1B Series C on August 19, 2026: $800M equity plus a $250M revolver, at $13B. JPM, a16z, and Carlyle co-led. Google still ranks the $350M Series B. Revenue was not disclosed.

**Castelion is worth $13 billion** after a **$1 billion Series C** on **August 19, 2026**. That package is **$800 million of equity** plus a **$250 million** committed revolver. **JPMorganChase’s Strategic Investment Group**, **[Andreessen Horowitz](/fund/andreessen-horowitz)**, and **Carlyle** co-led.

**Unexpected truth:** Google still ranks the **December 2025 $350 million Series B** and The Information’s **~$12 billion** target. The live company mark is **$13 billion**. **Revenue was not disclosed.**

This page is for people deciding whether Castelion (or this hypersonic-manufacturing lane) is worth another hour. Last verified **August 20, 2026**. Fact vs our read is labeled below.

## Five-minute decision

| If you need… | Verdict |
| --- | --- |
| What happened | **Funded.** $800M equity + $250M revolver @ **$13B**, Aug 19, 2026. JPM / a16z / Carlyle co-leads. |
| What Castelion is | Hypersonic **missile manufacturer**. Blackbeard first; longer-range strike and defense systems next. |
| Whether it is “shipping” | **Program of record**; company targets **2027 fielding**. Named contract dollars are a **>$500M** 18-month total, not a unit cadence. |
| Whether to diligence | **Yes**, if you underwrite production + procurement. **No**, if you need a revenue multiple before a first call. |

**Investigate further when:** you believe the scarce asset is **magazine depth at commercial unit cost**, and $13B is a factory print, not a software mark.

**Wait or pass when:** your bar is disclosed units/year, or you think [Anduril](/startup/anduril) already occupies the defense-tech allocation that would fund a hypersonic specialist.

## What happened

| Field | Detail |
| --- | --- |
| Company | Castelion ([castelion.com](https://www.castelion.com/)); CEO Bryon Hargis; HQ Torrance, CA |
| Round | **$1B Series C** = **$800M equity** + **$250M** committed revolver · **$13B** valuation |
| Date | August 19, 2026 (company + PR Newswire) |
| Equity co-leads | JPM Strategic Investment Group (Security and Resiliency Initiative); [a16z](/fund/andreessen-horowitz); Carlyle (no `/fund/` page) |
| Directory funds returning | [Lightspeed](/fund/lightspeed-venture-partners-nyc), [Altimeter](/fund/altimeter-capital), [General Catalyst](/fund/general-catalyst) |
| Other names in the PR | Lavrock Ventures, Interlagos, T. Rowe Price Associates (new; advised account) |
| Use of proceeds | Blackbeard production (Project Ranger + beyond); longer-range strike; defensive systems |
| Traction disclosed | **>$500M** U.S. military contracts in 18 months; program of record in under four years; fielding targeted **2027** |
| Prior close | **$350M Series B**, December 5, 2025, Altimeter + Lightspeed |

Do **not** treat **$1 billion** as all equity. The company splits **$800 million** stock and **$250 million** credit.

## What Castelion actually does

**Product (company):** **Blackbeard**, described as the first American hypersonic missile engineered from the start for industrial-rate output and commercial unit cost. Manufacturing includes mixing its own propellant in New Mexico (Lightspeed quote).

**Job:** give the U.S. and allies **hypersonic strike in quantity**, not a handful of exquisite rounds.

**Three spend lines in the PR:**

1. **More Blackbeard** at and beyond the 1,000-acre **Project Ranger** campus (Sandoval County, NM). Company: largest dedicated hypersonic missile plant in the U.S.; **>$250 million** already spent privately; “hundreds of millions more” now.
2. **Longer-range precision strike** that reuses Blackbeard tech — a cheaper complement to large exquisite systems.
3. **Air and missile defense** products using the same manufacturing model (magazine depth).

**Saronic overlap (June 11, 2026 company note):** [Saronic](/startup/saronic) and Castelion said they will demonstrate maritime hypersonic launch from Saronic autonomous surface vessels, targeting **2027**. That is a **demo plan**, not a disclosed offtake.

## How big is Castelion actually?

| Question | Disclosed? | What we have |
| --- | --- | --- |
| Valuation | **Yes** | **$13B** (company, Aug 19) |
| Equity | **Yes** | **$800M** |
| Credit | **Yes** | **$250M** committed revolver |
| Headline “$1B” | **Package** | Equity + revolver. Not $1B of primary stock. |
| Military contracts | **Company total** | **>$500M** over 18 months. One named piece: June 16 Navy **$23.4M** FFP for **50** Blackbeard EOC prototypes ([company](https://www.castelion.com/news/u-s-navy-awards-castelion-first-delivery-order-for-blackbeard-hypersonic-weapon/)) |
| Revenue / units / year | **No** | Interlagos *quote* talks about “thousands a year.” That is an investor, not a company 10-K. |
| Fielding | **Target** | **2027** (company) |
| Prior mark | **Close date** | Series B **Dec 5, 2025** ($350M). July 2025 TechCrunch was raise-in-progress. |
| Older SERP | **Stale** | The Information **~$12B target**; Forge/secondary pages. Live mark is **$13B**. |

**Contracts in aggregate, not a P&L.** That is the most useful number on this page besides $13 billion.

## Worked numbers (indicative)

1. **Setup:** Dec 5, 2025 — **$350M Series B** to mass-produce Blackbeard.
2. **Move:** Aug 19, 2026 — **$800M equity at $13B**, plus **$250M** credit for a production company.
3. **Punch:** If $800M is new primary at $13B post, implied dilution is about **6.2%** ($800M / $13B). That is **headline arithmetic**, not a disclosed option pool or preference stack. The revolver does **not** dilute.

Same-month defense tape (not Castelion’s P&L): [Neros](/startup/neros-technologies) printed **$2.5B** on **August 11**. [Heaviside](/startup/heaviside-industries) printed **$600M** on **August 12**. [Anduril](/startup/anduril) is **$61B** after May’s **$5B** Series H. Castelion sits between Neros and Anduril on **price**, and next to Heaviside on **Southern California munitions**.

## Castelion vs Anduril — what differs

| | Castelion | Anduril |
| --- | --- | --- |
| Latest mark | **$13B**, Aug 19, 2026 | **$61B**, May 2026 |
| Last raise | **$800M equity** + $250M revolver | **$5B** Series H |
| Product | Hypersonic **missiles** (Blackbeard) | Software-defined **defense platform** (drones, C2, c-UAS) |
| What “scale” means | Factory + magazine depth | Lattice + many vehicle classes |
| Directory leads this print | [a16z](/fund/andreessen-horowitz) co-lead; JPM + Carlyle | [Thrive](/fund/thrive-capital) + [a16z](/fund/andreessen-horowitz) |
| Main risk | Procurement + explosives manufacturing | Breadth vs primes |

Choose Castelion when you are underwriting **hypersonic production**. Choose Anduril when you are underwriting a **software-defined defense conglomerate**. Do not mash the two $B marks.

Castelion vs [Neros](/startup/neros-technologies): both Torrance-area manufacturers raising in August 2026. Neros is **attritable drones** at **$2.5B**. Castelion is **hypersonic missiles** at **$13B**. Same week, different payloads.

## Why investors likely wrote $800M

### Known evidence (company + named quotes)

- **>$500M** in U.S. military contracts over 18 months (company).
- Program of record in under four years; **2027** fielding target.
- Project Ranger already took **>$250M** of private infrastructure spend.
- Katherine Boyle ([a16z](/fund/andreessen-horowitz)): factory in New Mexico and a production agreement with the department named in her quote.
- Ravi Mhatre ([Lightspeed](/fund/lightspeed-venture-partners-nyc)): led Series A before a complete system had flown; now “shipping hardware to the services.”
- Bank + PE + venture in one syndicate (JPM, Carlyle, a16z) — credit sits next to equity because this is a **plant**.

### Our interpretation (not an IC memo)

| Bet | Why it could justify $13B |
| --- | --- |
| Production, not a slide | Campus + propellant + program of record |
| Credit attached | $250M revolver is how you fund working capital once contracts exist |
| Category FOMO | Defense mega-rounds (Anduril $61B, Saronic $9.25B) already cleared the path |
| Cost-per-round | Company thesis is commercial unit cost vs exquisite hypersonics |

**What we cannot claim:** a revenue multiple, units/year, or that Interlagos’s “thousands a year” is current run-rate.

## What has to be true for Castelion to win

1. **2027 fielding** happens with enough rounds to matter, not a ceremony.
2. Project Ranger’s extra “hundreds of millions” actually **raise output**.
3. The longer-range and defensive products do not **dilute** Blackbeard execution.
4. The **>$500M** contract total converts on schedule.
5. JPM/Carlyle credit stays available if working capital spikes.

## What could break the thesis

- Hypersonic **test or production** slips past the 2027 language.
- Primes match cost at a volume Castelion cannot finance.
- The $13B mark was a **scarcity print** that later public comps will not pay.
- Mixing **$800M equity** and **$250M debt** in Slack as “$1B of dilution.”

## When not to use this page

- Do not treat **$13B** as the December 2025 figure. December was the **$350M B**.
- Do not treat The Information’s **~$12B target** as the live mark.
- Do not invent a `/fund/` page for Carlyle, JPM, Lavrock, Interlagos, or T. Rowe.
- Do not use Interlagos’s “thousands a year” as a company unit disclosure.
- Do not confuse this ALSO-week **physical AI** tape with [ALSO](/startup/also-mobility) the Rivian spinout.
