Elon Musk announced on Monday that SpaceX and his artificial intelligence company xAI will merge in a deal valuing the combined entity at US$1.25-trillion. The move, pitched as an effort to build AI compute infrastructure in orbit, pushed several U.S. publicly traded space companies higher on Tuesday.
Musk said moving AI compute into space could be the most cost-effective approach within two to three years as companies chase artificial general intelligence, a theoretical point at which machines would match or exceed human cognitive abilities.
Market reaction
Stocks of firms tied to launch services, satellite data and space hardware rose in premarket trading as investors adjusted expectations for demand. Rocket Lab and Planet Labs both climbed about 3 per cent. AST SpaceMobile gained roughly 2.4 per cent and Globalstar added about 1.3 per cent. Intuitive Machines rose 2.1 per cent and Redwire advanced 4.9 per cent.
The gains reflected both near-term speculation over new contracts and longer-term bets that a Musk-led, vertically integrated space business would increase demand for launch capacity, satellite manufacturing and in-orbit services.
What Musk announced
Musk described the merger as an attempt to build a single organisation combining AI, rocket technology, space-based internet services, direct-to-mobile communications and a platform for real-time information and free speech. He has also signalled plans for a major SpaceX public offering later this year, which people familiar with the matter have said could value the company at more than US$1.5-trillion.
xAI was last valued at about US$230-billion in November, according to the Wall Street Journal. The merger brings together two of the largest privately held companies in the world under Musk’s broader technology and space strategy.
Why investors and analysts are paying attention
Analysts and investment managers framed the deal as validation that space can play a central role in the next phase of computing. AJ Bell investment director Russ Mould said the combination could heighten interest ahead of what might be an exceptionally large IPO.
Others may buy into Musk’s grand vision of data centres in the cosmos, and this may only whet the appetite ahead of what could be the largest IPO of all time.

Investment firm Seraphim Space has pointed to rising global investment in space technology, supported by government spending on defence-linked satellite systems and private sector bets on launch capacity and in-orbit services. Seraphim Space CEO Mark Boggett called the merger a strong validation for space’s role in AI.
This is the strongest validation yet that space will be the backbone of the next wave of AI.

Technical and regulatory implications
SpaceX has requested permission to launch a constellation of up to 1 million satellites, which Musk’s team says could provide solar-powered compute and communications platforms in orbit. The proposal underscores growing interest among tech firms in reducing reliance on terrestrial data centres, which consume large amounts of electricity and water for cooling.
Regulators will evaluate orbital congestion, frequency coordination and space sustainability as proposals move forward. Any plan to host large-scale computing in space would also require new supply chains for launch, satellite manufacturing and in-orbit servicing.
What investors will watch next
- Details and timing for a potential SpaceX initial public offering and its estimated valuation
- Regulatory approvals for large satellite constellations and frequency licences
- Commercial partnerships or contracts that tie traditional data-centre workloads to in-orbit services
- Capital spending by launch providers and satellite manufacturers to meet projected demand
Short-term stock moves are likely to reflect optimism about future contracts and revenue streams, while longer-term valuations will depend on tangible milestones: regulatory approvals, successful launches, and evidence that in-orbit compute can be delivered at scale and cost-effectively.
The broader picture
The merger ties into a broader trend: increased government spending on defence and strategic satellite capability, combined with private investment in launch infrastructure and satellite services. That confluence has pushed more capital into space startups and public companies servicing the sector.
For Toronto-based and Canadian investors, the development reinforces interest in companies that provide launch hardware, satellite components, and ground systems that support expanded orbital activity.
The SpaceX-xAI merger marks a significant step in the debate over where the next generation of computing will run. Investors and regulators will spend the months ahead testing whether the technical and commercial case for orbital AI can be made at scale.
