DeepSeek Raises $15 Billion in Defiant Move Amid US Security Crackdown

Just 48 hours after the United States mandated that federal civilian agencies strip DeepSeek’s artificial intelligence technology from their networks, the Hangzhou-based startup has reportedly closed a funding round of approximately $15 billion. This sum, equivalent to roughly 100 billion yuan, represents one of the largest capital raises in Chinese history and lands with particular weight given the immediate timing relative to the U.S. security directive. The move suggests that the lab views the recent regulatory friction not as a barrier to growth, but as a catalyst to accelerate its infrastructure buildout and market penetration.

According to Bloomberg, the investor lineup for this latest round includes major Chinese corporate entities, most notably CATL, a leading battery manufacturer, and Tencent, the company responsible for the WeChat messaging platform. The presence of such high-profile backers indicates a broad consensus among domestic tech giants that DeepSeek remains a central player in the national AI strategy, regardless of the current diplomatic or technical tensions with Washington.

To understand the scale of this financial surge, it is necessary to look back at the company’s recent trajectory. In June, DeepSeek completed a previous investment round, securing over $7 billion at a valuation of $50 billion. By July, reports indicated the company was already seeking an additional $1.5 billion, pushing its valuation to around $71 billion. These figures laid the groundwork for the current raise and were accompanied by speculation about a potential Initial Public Offering in China as early as next year, a path that would further cement its status as a market leader.

The decision to raise such a substantial amount of capital comes as the company ramps up spending on both AI infrastructure and open-source models. The stated goal is to serve both domestic and international markets, a strategy that appears to be continuing unabated despite the restrictions placed on it in the U.S. This aggressive expansion is likely to intensify competition among other domestic rivals, forcing them to match DeepSeek’s pace of development and deployment to remain competitive in the crowded Chinese AI landscape.

DeepSeek’s funding round is part of a broader global trend where investors are pouring billions into AI firms to maintain an edge in the international race. In May, Moonshot AI, the developer behind the Kimi model, secured $2 billion at a $20 billion valuation. More recently, Manus AI raised over $500 million earlier this month. On the public markets, Chinese AI firms that listed in Hong Kong in January are showing strong performance; Zhipu AI (Z.ai) and MiniMax currently hold market capitalizations of approximately $29 billion and $7.2 billion, respectively, as of this week.

The company’s origins are rooted in the financial sector. DeepSeek was founded in 2023 by Liang Wenfeng, who previously co-founded High-Flyer, a Chinese quantitative hedge fund. High-Flyer played a crucial role in financing DeepSeek’s early development, providing the initial capital needed to establish the lab. This financial background has arguably given the company a unique approach to resource allocation and risk management compared to other tech startups.

DeepSeek first captured global attention in early 2025 when it released a free-to-use, open-weight reasoning model. This release was significant because it challenged the perceived dominance of U.S.-based AI companies, demonstrating that high-quality, accessible AI technology could be developed outside of the American ecosystem. The model’s availability and performance forced a reevaluation of the global AI power dynamics, positioning DeepSeek as a serious contender on the world stage.

Despite the recent funding and global attention, Liang Wenfeng maintains significant control over the company. Following the earlier funding round, corporate ownership data analyzed by WireScreen indicates that Liang retains an estimated 81.6% stake in DeepSeek’s Chinese operating entity. This high level of ownership suggests that the founding team remains firmly in charge of strategic direction, even as the company brings in massive amounts of external capital.

As of now, DeepSeek has not issued an official statement regarding the new funding round or its response to the U.S. restrictions. The company did not immediately respond to a request for comment, leaving the specifics of how the new capital will be deployed and how the firm will navigate the ongoing regulatory environment to be seen in the coming weeks.
