Sidus Space’s Sudden Liftoff: How A Tiny Defense Win Sparked A Massive Rally

Pentagon backing for more AI-powered data solutions and a part of the Golden Dome contract has helped Sidus Space see a surge.

• Last week, Sidus Space said it was one of the contract awardees for a broader Golden Dome missile defense strategy.
• On Monday, Sidus Space shares jumped 33% following the announcement of the closing of its previously announced offering of nearly 11 million shares of its Class A common stock.
• In early December, Sidus Space announced that it would be a subcontractor supporting MobLobSpace under a NASA Small Business Innovation Research award.

A month ago, Sidus Space was barely a blip in the broader space-stock rally. Today, it’s one of the market’s most eye-catching movers. The company’s shares have more than tripled in just four weeks, a surge driven less by speculative hype than by steady expansion of its core capabilities.

Sidus has been quietly broadening its footprint beyond satellites, leaning into end-to-end space manufacturing, AI-driven data solutions, and space and defense hardware, a strategy that’s now beginning to resonate with investors.

That move comes against a favorable backdrop for the sector. Space stocks have enjoyed a strong year, lifted by SpaceX IPO chatter, an uptick in launch activity, and President Donald Trump’s executive order calling for a U.S. return to the Moon by 2028.

But Sidus’ recent run stands apart. Despite still being down about 48% year-to-date, the stock has staged a sharp reversal after being named one of the contract awardees under the U.S. government’s “Golden Dome” missile defense initiative, which aims to build a layered, resilient defense system spanning air, missile, space, cyber, and hybrid threats.

The Golden Opportunity

Last week, the company said that it was awarded the contract under the Missile Defense Agency (MDA) Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) indefinite-delivery/indefinite-quantity (IDIQ) contract with a total IDIQ ceiling of $151 billion.

The SHIELD contract vehicle provides a mechanism for the rapid delivery of innovative capabilities to the warfighter, increasing speed and agility. It leverages artificial intelligence and machine learning enabled applications where applicable and maximizes the use of digital engineering and open systems architectures.

Closing Of Public Offering

On Monday, Sidus Space shares jumped 33% following the announcement of the closing of its previously announced offering of nearly 11 million shares of its Class A common stock. Each share of Class A common stock was sold at an offering price of $1.50 per share for gross proceeds of approximately $16.2 million.

The company said that the capital raise is intended to be used for sales and marketing, operational costs, product development, manufacturing expansion, working capital, and general corporate purposes.

Sidus’ 2025 In A Nutshell

In early December, Sidus Space announced that it would be a subcontractor supporting MobLobSpace under a NASA Small Business Innovation Research award. The six-month design study will focus on planning and designing a mission to host an advanced space-based 4D radar system on Sidus’ LizzieSat satellite platform, delivering critical Space Domain Awareness data services to track centimeter-scale orbital debris.

This year, Sidus Space completed the on-orbit operation of its advanced onboard edge computer, FeatherEdge GEN-2, integrated into the ongoing commissioning of LizzieSat-3.

FeatherEdge GEN-2 is flight-proven and commercially available, offering 100 trillion operations per second of AI processing power in a space-hardened, compact format. The computer leverages NVIDIA’s Jetson Orin NX module and is built to perform in harsh radiation environments, making it ideal for sustained low Earth orbit missions.

In September, the company was also awarded a five-year Indefinite Delivery/Indefinite Quantity contract under the Tobyhanna Army Depot Industrial Multiple Award Task Order Contract program.
