Elon Musk’s artificial intelligence startup xAI is looking to raise $4.3 billion from equity investors, after raising $5 billion in bonds. Meanwhile, the company is facing accusations of causing serious air pollution in Memphis.

xAI, the artificial intelligence company founded by Elon Musk in 2023, is in the process of raising another $4.3 billion from equity investors. This is the next step after the company sought $5 billion from bond investors, according to Bloomberg.

As of the end of March 2025, xAI had raised a total of $14 billion from previous funding rounds, but currently has only about $4 billion on hand. The large spending in a short period of time has left the company in need of capital to maintain operations, especially in the context of accelerating the development of the Grok chatbot – a product that directly competes with ChatGPT.

xAI’s $5 billion bond offering includes a term loan, a fixed-rate loan, and a secured bond. The company is also selling $300 million in stock so employees can sell shares to investors.

xAI is targeting a $113 billion valuation, with a larger funding round expected to follow.

xAI Accused of Air Pollution in Memphis

While focusing on fundraising, xAI has been hit with serious allegations from the NAACP (National Association for the Advancement of Colored People). The organization, through the Southern Environmental Law Center (SELC), has just sent a warning letter to prepare to sue xAI for air pollution at a data center in Memphis, Tennessee.

Specifically, xAI is accused of installing dozens of methane turbines at its South Memphis facility without a permit and without an emission control system required by the federal Clean Air Act. This is said to have exacerbated the already severe pollution in the area.

The data center is located near predominantly black neighborhoods that have been plagued by industrial pollution for decades. The Boxtown area alone has a cancer risk rate four times higher than the national average.

The SELC letter is a 60-day legal notice – a mandatory step before filing a formal lawsuit under US law.

Since 2024, when xAI began operating its Memphis data center, local residents have repeatedly protested, claiming that the company’s operations are harmful to the environment. Hundreds of residents have filed complaints with the Shelby County Health Department about the use of unregulated gas turbines.

In addition to its South Memphis facility, xAI is also building a second data center in the Whitehaven area. However, the company has not disclosed the energy source for this new project, raising concerns that a similar pollution scenario will occur again.

The public backlash in Memphis has been growing, putting pressure on xAI as the company expands and faces legal challenges.

Elon Musk is the richest person in the world, but xAI is still struggling financially?

As of June 17, Elon Musk is still the richest person in the world with an estimated total fortune of $406.6 billion, according to Forbes. However, his fortune has decreased by $6.4 billion compared to the previous session, reflecting market fluctuations and the value of the companies Musk owns.

Despite his huge fortune, Musk is still raising billions of dollars for xAI. This shows that the cost of developing AI technology is extremely large and it is difficult to rely on personal capital – even for the world’s top billionaires.

xAI’s continuous fundraising also raises questions about the sustainability of its business model, when most resources are being poured into a few products, especially the Grok chatbot – a competitor to popular AI tools such as ChatGPT, Claude or Gemini.

Elon Musk founded xAI with the ambition to compete in the global artificial intelligence race. The current flagship product is the Grok chatbot – a tool integrated into the social network X (formerly Twitter) – to serve users in a way that both provides information and entertainment, and has a more “rebellious” style than ChatGPT.

However, to achieve this goal, xAI must mobilize tens of billions of dollars to invest in supercomputers, data centers, hire experts and develop software – all of which are areas that require extremely large costs.

Rapid development without a stable source of revenue means xAI needs to continuously raise capital to maintain operations. At the same time, legal risks and social reactions – like in Memphis – can become major obstacles to the company’s development journey.
