US space stocks rise after SpaceX merges with xAI at $1.25 trillion valuation

U.S. space-related stocks climbed after SpaceX announced a merger with xAI, valuing the combined entity at $1.25 trillion. The deal, unveiled by Elon Musk, signals a major push to expand artificial intelligence infrastructure beyond Earth and into orbit, a vision that has energized investors across the emerging space sector.

Shares of listed space companies rallied following the announcement. Rocket Lab, Planet Labs, AST SpaceMobile, Intuitive Machines and Redwire all posted gains, reflecting growing optimism that space-based infrastructure could play a central role in the next phase of AI development. Musk has said that within two to three years, generating AI computing power in space could become more cost-effective than on Earth, thanks to near-constant solar energy and reduced cooling constraints.

The merger brings together rocket launches, satellite networks, AI software and communications platforms under one umbrella, forming what Musk described as a vertically integrated innovation powerhouse. Analysts said the move strengthens SpaceX’s positioning ahead of a potential public offering later this year, which could value the company above $1.5 trillion. The announcement has also fueled expectations of increased investment in space technology, driven by both government defense spending and private-sector demand for AI-related infrastructure.

SpaceX acquires xAI in record-setting deal as Musk unifies AI and space ambitions

SpaceX has acquired xAI in a record-setting transaction, consolidating Elon Musk’s artificial intelligence and space businesses into a single platform. The deal, first reported by Reuters, values SpaceX at about $1 trillion and xAI at roughly $250 billion, according to people familiar with the matter, making it the largest merger and acquisition transaction on record.

Under the terms, xAI investors will receive 0.1433 SpaceX shares for each xAI share, with some executives able to opt for cash at $75.46 per share. The combined entity is expected to price shares near $527. The tie-up brings together SpaceX’s launch and satellite capabilities, including Starlink, with xAI’s Grok chatbot and AI development, potentially strengthening plans for data centers and AI services delivered from orbit.

The move further integrates Musk’s businesses as he competes with rivals such as Alphabet, Meta, Amazon, and OpenAI. Analysts say the deal could enhance SpaceX’s narrative ahead of a potential public offering later this year, while also raising governance and regulatory questions given SpaceX’s extensive U.S. government contracts.

Apple warns rising memory costs as AI chip demand tightens supply

Apple warned that increasing memory chip prices are beginning to weigh on profitability, as major suppliers shift production toward higher-margin chips used in artificial intelligence systems. Chief executive Tim Cook said market pricing for memory has risen sharply and is expected to have a greater impact in the current quarter, following only limited effects during the key holiday period.

The comments echo recent warnings from South Korean chipmakers Samsung Electronics and SK Hynix, which together dominate the global DRAM market. Both companies have been prioritising high-bandwidth memory used in AI servers, tightening supply of conventional DRAM chips used in smartphones, personal computers, and consumer electronics.

Apple is likely to require more memory components as demand for its latest iPhone models remains strong, particularly in China and India. However, the company declined to say whether higher component costs could translate into increased product prices. Analysts warn that sustained memory shortages could pressure margins across the consumer electronics sector and disrupt supply chains.

Chipmakers have also become more cautious about expanding capacity after years of aggressive investment, limiting the pace at which supply can respond. As AI infrastructure spending accelerates, memory availability for traditional devices is expected to remain constrained, contributing to weaker outlooks for global smartphone and PC shipments in the coming years.
