xAI burns $6.4 billion as SpaceX IPO filing reveals why AI spending will accelerate further

xAI Posts $6.4 Billion Operating Loss as SpaceX IPO Filing Exposes Financial Reality

Elon Musk's xAI burned through $6.4 billion in operating losses on just $3.2 billion in revenue during 2025, according to the SpaceX IPO filing released this week1

1

. The disclosure marks the first public glimpse into xAI's financial performance since Elon Musk merged his AI company with SpaceX in February, following xAI's earlier acquisition of social media platform X. The widening gap between revenue and spending stands in stark contrast to competitor Anthropic, which reportedly expects a 130% revenue jump to $10.9 billion in the second quarter, leading to its first operating profit1

1

. The losses represent a dramatic escalation from 2024, when xAI recorded a $1.56 billion loss on $2.62 billion in revenue, signaling that the company's cash burn is accelerating rather than stabilizing.

AI Infrastructure Spending Reaches $30.8 Billion Annualized Run Rate

The SpaceX IPO filing reveals that AI segment capital expenditures climbed from $12.7 billion in 2025 to $7.7 billion in the first quarter of 2026 alone, translating to an annualized capex run rate of approximately $30.8 billion1

1

. This represents more than a doubling year-over-year and underscores the massive investment required to compete in frontier AI development. The company's Colossus and Colossus II data centers, which came online in 122 days and 91 days respectively, collectively provide about 1 gigawatt of AI compute power for Grok's training and inference1

1

. SpaceX claims that owning the compute infrastructure and pursuing vertical integration across the AI stack enables them to train and iterate frontier models at lower cost and higher velocity, though the financial results suggest profitability remains distant.

Grok Chatbot Reaches 117 Million Users But Adoption Remains Limited

Despite the massive investment in AI and Space Infrastructure, user adoption of Grok features remains modest. The filing shows SpaceX recorded 117 million monthly active users for Grok AI features as of March 2026, out of 550 million total MAUs across Grok and X combined1

1

. This means only one-fifth of the combined ecosystem actively uses Grok AI features. Revenue from AI solutions and infrastructure totaled $465 million, including $365 million from X and Grok subscription revenue and $88 million from data licensing, with an additional $116 million coming from advertising1

1

. The company is aggressively pursuing finance sector growth, with Apollo Global Management, Morgan Stanley, and Valor Equity Partners beginning to test the Grok chatbot internally4

4

. However, financiers are rarely using the chatbot for actual work, and xAI's tools are widely viewed as inferior to those from OpenAI and Anthropic for the finance industry4

SpaceX Targets $1.75 Trillion Valuation Despite AI Unit Losses

The SpaceX IPO filing, which names Goldman Sachs, Morgan Stanley, Bank of America, Citi, and JPMorgan among lead underwriters, targets a valuation of $1.75 trillion, potentially making it the largest IPO in history2

2

. For 2025, SpaceX reported $18.67 billion in revenue alongside a $2.59 billion operating loss, with the AI segment posting $6.36 billion in operating losses and Starship research and development consuming roughly $3 billion2

2

. The filing reveals a dual-class share structure preserving Elon Musk's control, with public investors receiving Class A shares carrying one vote each while Musk's Class B shares carry 10 votes apiece2

2

. A 5-for-1 forward split cut the fair value per share to about $105.32 from $526.59, lowering the entry point for retail investors3

. Polymarket's timing market prices a June listing at 94%, with reports targeting a Nasdaq debut on June 12 under ticker SPCX3

Plans for Trillions of Parameters and Orbital Data Centers Signal More Spending

The SpaceX IPO filing states that xAI's next-generation AI is expected to scale Grok to multiple trillions of parameters, described as a step change in reasoning depth and overall intelligence1

1

. This ambitious target will undoubtedly require more investment, with the use of proceeds section mentioning expansion of AI compute infrastructure. Looking further ahead, SpaceX intends to begin deploying orbital data centers as early as 2028, the first concrete timeline for such a launch1

1

. Musk has promised that orbital AI compute satellites will be a much cheaper alternative to terrestrial data centers, though this sci-fi vision won't materialize for several years. The filing declares that the future of AI will be determined by control of the physical stack1

1

. Meanwhile, xAI reportedly burned through almost $1 billion per month in the runup to its merger with SpaceX4

4

, and the company is training Grok for financial modeling work by teaching it to read documents and Excel spreadsheets5

5

. Much of xAI's sales to date have come from deals with Musk's other ventures, including SpaceX and Tesla4

4

. The company has also recruited executives from across Musk's empire, with SpaceX President Gwynne Shotwell overseeing operations, Starlink executive Michael Nicolls serving as xAI president, and SpaceX finance chief Bret Johnsen running xAI's books3

3

. As both OpenAI and Anthropic eye public debuts in 2026, Wall Street will be watching whether xAI can narrow its losses and demonstrate a viable path to competing with established AI leaders.
