MGX Joins Anthropic’s $30 Billion Raise, Holding Stakes in OpenAI and xAI

U.S.-based AI company Anthropic has raised $30 billion in a Series G round at a reported $380 billion post-money valuation. Among the named co-leads in the round is MGX, the Abu Dhabi-backed investment vehicle that has rapidly emerged as one of the most assertive capital allocators in frontier AI.

While the headline centers on Anthropic’s valuation, the deeper story may lie thousands of miles away in the Gulf. With this latest investment, MGX now holds positions across the trio of leading U.S. frontier AI labs, Anthropic, OpenAI and xAI. In a May 2025 board update, MGX publicly referenced investments spanning OpenAI, Anthropic, and xAI, signaling a deliberate strategy to back the foundational model developers shaping the next era of machine intelligence.

This is not opportunistic investing. It is portfolio construction at the level of infrastructure.

Anthropic, best known for its Claude family of large language models, said the Series G funding will support scaling advanced AI systems, expanding research, and strengthening safety-focused development. The company emphasized its continued focus on building reliable, interpretable, and steerable AI systems, language consistent with its long-standing positioning around alignment and responsible deployment.

The funding round reflects more than investor appetite for generative AI. It marks the continued concentration of capital into a small cluster of labs that design and train the world’s most advanced foundation models. Those models increasingly serve as the backbone for enterprise software, developer tools, and consumer AI products worldwide.

MGX’s involvement signals that Abu Dhabi does not intend to merely import these technologies, it intends to influence their trajectory.

The strategy mirrors sovereign investment playbooks seen in energy, aviation, and semiconductor infrastructure: secure early exposure to core enabling technologies, then build domestic ecosystems around them. In AI, that means anchoring relationships with the companies that control model architectures, training pipelines, and next-generation compute partnerships.

Beyond Anthropic, MGX also appeared among investors in xAI’s $20 billion Series E round.

AI capabilities are increasingly viewed not just as commercial tools but as national assets. Foundation models influence productivity, defense research, financial systems, healthcare diagnostics, and even information flows. Ownership stakes in the companies developing these systems offer insight into technical roadmaps, governance structures, and ecosystem partnerships.

This is a different posture from passive financial participation. It reflects a shift toward technological alignment.

Anthropic’s valuation itself underscores how quickly the economics of frontier AI have evolved. With a $380 billion post-money figure, the company joins a rarefied class of private technology firms whose valuations rival major publicly listed enterprises. The funding scale also highlights the capital intensity of training next-generation models, which require vast computing infrastructure and long research cycles.

MGX’s involvement suggests confidence not only in Anthropic’s commercial prospects but in the structural role foundation models will play in the global economy.

In recent years, Gulf sovereign capital has moved from minority stakes in mature Western companies toward earlier-stage participation in high-growth technology platforms. AI appears to be the clearest expression of that pivot.

Rather than focusing on downstream applications, chatbots, productivity layers or vertical SaaS integrations, MGX has concentrated on the core model builders. The approach resembles investing in semiconductor fabs rather than consumer electronics brands. Control and influence reside at the base layer.

As AI power consolidates among a limited number of labs capable of training frontier-scale systems, capital allocation becomes intertwined with geopolitics. Access to compute, chips, and research talent increasingly shapes national competitiveness.

By securing positions in Anthropic, OpenAI, and xAI, MGX is placing Abu Dhabi within the financial architecture of the AI race.

Anthropic’s Series G announcement frames the raise as a step toward building more capable and trustworthy AI. For MGX, the step appears equally calculated: anchor the emirate in the ownership structures of the technologies likely to define the next industrial cycle.

The story, in that sense, is less about valuation headlines and more about positioning. Abu Dhabi is not simply funding AI’s future. It is buying a seat at the table where that future is designed.
