Elon Musk's xAI reports $1.46 billion loss as startup rapidly expands operations what we know
Heavy losses amid aggressive growth
Elon Musk’s artificial intelligence venture xAI is burning cash at a rapid pace as it scales operations. According to internal documents cited by Bloomberg, the startup reported a net loss of $1.46 billion in the September quarter, up from a $1 billion loss in the previous quarter. The losses reflect heavy investments in building data centers, recruiting top AI talent, and developing advanced software intended to power future humanoid robots.
Spending surges to $7.8 billion in nine months
In the first nine months of the year, xAI spent approximately $7.8 billion in cash. Like many fast-growing AI startups, the company is rapidly deploying funds raised in recent financing rounds. Executives told investors that the spending is intentional and aligned with xAI’s long-term ambition to build self-sufficient AI systems that can operate autonomously at scale.
Building AI for humanoid robots
A key long-term objective is to develop AI that can eventually power humanoid robots such as Optimus, created by Tesla Inc.. xAI leadership has emphasized that current efforts are focused on rapidly developing AI agents and core software. These technologies are expected to feed into an internal concept referred to as “Macrohard,” which Musk has described as an AI-only software ecosystem designed to rival traditional software platforms and ultimately support robotics like Optimus.
Revenue growth shows early traction
Despite mounting losses, xAI’s revenue is rising quickly. Financial documents shared with investors show that revenue nearly doubled quarter-over-quarter to $107 million for the three months ended September 30, 2025. Through September, the company reported more than $200 million in sales, though this still falls short of its earlier full-year target of $500 million.
Improving gross profit, but negative EBITDA
xAI’s gross profit has increased significantly, reaching $63 million in the third quarter compared to $14 million in the previous quarter. However, overall profitability remains distant. EBITDA losses reached $2.4 billion through September, exceeding the company’s earlier projection of a $2.2 billion loss for the full year. Executives maintain that such losses are typical for capital-intensive startups in hyper-growth phases.
Intertwined with Musk’s broader ecosystem
Musk’s businesses often share resources and strategic direction, and xAI is no exception. Grok, xAI’s chatbot, is fully integrated into X, the social platform formerly known as Twitter, and is also available in Tesla vehicles. SpaceX has invested in xAI, while xAI has spent hundreds of millions of dollars on Tesla Megapack batteries. Although Musk has supported closer ties between Tesla and xAI, Tesla shareholders recently voted against a non-binding proposal for the automaker to invest in xAI.
Leadership changes and investor outlook
The investor call also marked the first major update from newly appointed leadership. Anthony Armstrong, a former Morgan Stanley banker, joined as Chief Financial Officer, while Jon Shulkin took on the role of Chief Revenue Officer. Executives expressed optimism about revenue growth and signaled confidence that xAI has sufficient resources to continue spending aggressively as it races toward what they describe as “escape velocity” in AI development.
Funding strength and talent costs
To date, xAI has raised at least $40 billion in equity, including a $20 billion round announced earlier this month. The company has also paid nearly $160 million in stock-based compensation through September, underscoring the intense competition for elite AI talent. While losses are higher than initially expected, investors appear focused on xAI’s rapid scaling, improving gross margins, and its central role in Musk’s broader vision for AI-driven automation and robotics.
