Liang Wenfeng, the hedge fund billionaire who spent years refusing outside money for his AI company DeepSeek, has finally opened the door—and it was the Chinese government that walked through first.
The China Integrated Circuit Industry Investment Fund, known as the Big Fund, is leading what has become a $7.35 billion investment at a valuation that skyrocketed from $10 billion in mid-April to as much as $50 billion by early May, according to Reuters and Fortune reporting. The same government vehicle that bankrolls China's biggest chipmakers is now the controlling investor in one of the country's most prominent AI companies.
This isn't an isolated transaction. According to a PitchBook analyst note, government-linked investors in China went from fewer than 10 AI deals per year before 2018 to more than 140 deals in 2025—roughly a 15-fold increase in participation. In semiconductors, which both DeepSeek and the Big Fund prioritize, the state's footprint is even more pronounced, with median deal sizes climbing to over $30 million in 2026.
"The state recognizes they can't really match what Nvidia or the rest of the world's AI giants are doing," Kaidi Gao, senior VC analyst at PitchBook, told Fortune. "But there is a different game that they can play. They can deploy capital into what are the most readily addressable sectors"—semiconductors, compute infrastructure, and hardware.
In China, as across Asia, long-term strategic thinking guides policy—what appears reactive is often planned. The emphasis on state capital in AI reflects lessons learned from U.S. semiconductor export controls and represents Beijing's determination to build technological self-sufficiency in critical sectors. The Big Fund's involvement ensures alignment with national industrial policy while providing the massive capital injections private markets alone cannot sustain under Western investment restrictions.
The funding surge follows a clear pattern. Other Chinese AI companies have raised enormous rounds in recent months: Moore Threads secured $720 million at a $4.1 billion valuation in February 2025, Moonshot AI raised $700 million at $10 billion in January 2026, and StepFun attracted $717 million the same month. In each case, state-linked entities featured prominently among investors.
The structural shift became more explicit in late April 2026, when China's top economic planning body instructed Moonshot AI, StepFun, and ByteDance to obtain government clearance before accepting U.S. capital. This regulatory tightening mirrors—and responds to—the U.S. ban on American investors backing Chinese AI and chip companies that took effect in January 2025.
The DeepSeek investment marks a watershed in China's approach to AI development. Where private entrepreneurship and market-driven innovation characterized the sector's early growth, the government is now actively structuring capital flows to ensure strategic priorities align with national security imperatives. For foreign companies and governments watching China's AI trajectory, the message is clear: the era of private-sector-led Chinese AI development has given way to state direction, with implications for everything from global supply chains to technological competition.
DeepSeek's capitulation to state investment—after years of independence—signals that even the most successful private AI firms in China ultimately operate within frameworks defined by Beijing. As U.S.-China technological competition intensifies, the Big Fund's entry into AI finance represents not just a funding round but a strategic repositioning of China's innovation ecosystem under centralized control.
