Wall Street Stunned as SpaceX Backs xAI in Record-Breaking $5B Equity Round!

Wall Street was left reeling this week as SpaceX committed a staggering $2 billion to Elon Musk’s artificial intelligence venture, xAI, in a record-smashing $5 billion equity round. The move signals a new era of crossover between Musk’s most ambitious companies.

The $5 billion equity raise, finalized in July 2025, is part of a broader $10 billion fundraising effort that includes a matching debt package. Top investors from Silicon Valley and beyond rushed to participate, drawn by xAI’s meteoric rise and Musk’s relentless vision.

SpaceX and xAI join forces in a historic funding round

SpaceX’s $2 billion stake is the largest single commitment in the round, cementing a deeper alliance between Musk’s space and AI empires. Other major backers include Andreessen Horowitz, Sequoia, VY Capital, BlackRock, Fidelity, NVIDIA, AMD, and Saudi conglomerate Kingdom Holdings.

Expected to play a significant role, the Saudi sovereign wealth fund PIF reflects global confidence in xAI's trajectory. The funding values xAI and its newly merged partner X (formerly Twitter) at a combined $113 billion, up dramatically from just $80 billion earlier this year.

Wall Street reacts to Musk’s bold AI ambitions

The sheer scale of the funding round has shocked analysts and investors, who see it as a direct challenge to established AI giants like OpenAI and Google. xAI’s flagship chatbot, Grok, is now positioned to leverage X’s 600 million active users for real-time data and rapid learning.

Musk aims to establish a vertically integrated tech powerhouse that consolidates social media, AI, and space technology under a single corporate umbrella. The merger of xAI and X, completed in March 2025, streamlined data sharing and gave investors exposure to both platforms’ explosive growth.
