In the cacophonous world of Chinese finance, where high-profile retail traders and loud-mouthed fund managers often fight for the spotlight, Liang Wenfeng has long remained a quiet enigma. Yet, the founder of the quantitative powerhouse High-Flyer Quant and the artificial intelligence lab DeepSeek is currently executing what may be the most significant self-funded tech expansion in mainland history.
DeepSeek has reportedly closed its inaugural external funding round, securing 50 billion RMB ($6.9 billion USD) at a staggering $50 billion USD valuation. The transaction is unconventional by every metric: Liang himself personally subscribed to 20 billion RMB of the commitment, demonstrating a level of conviction—and personal liquidity—that dwarfs the most famous retail titans of the Shanghai and Shenzhen exchanges.
Liang’s ability to anchor such a massive round stems from the extraordinary profitability of High-Flyer Quant. In 2025, the firm reportedly achieved a 56.55% return, generating nearly 40 billion RMB in gains for clients. This performance translated into approximately 8.6 billion RMB in management and performance fees, the lion’s share of which belongs to Liang as the 85% majority owner. Over a decade of such dominance has effectively turned his quant operation into a private treasury for his AI ambitions.
The structure of this new capital injection is a masterclass in strategic control. Most investors, including corporate giants like Tencent, NetEase, and CATL, have entered through limited partnerships that grant no voting rights and impose a strict five-year lock-in period. This arrangement effectively filters out speculative capital seeking a quick exit, ensuring that DeepSeek’s management remains insulated from the commercial volatility that has plagued Western counterparts like OpenAI.
Significantly, the only external entity granted voting power and a lack of restrictive lock-ups is the state-backed National Integrated Circuit Industry Investment Fund, commonly known as the 'Big Fund.' This involvement signals DeepSeek’s transition from a private research laboratory into a pillar of China’s national AI infrastructure. By aligning with state interests, Liang is positioning DeepSeek as a protected national champion for industrial intelligence.
The timing of the fundraise is also a defensive maneuver against a fierce domestic talent war. Following the departure of key researchers to rivals like ByteDance and Xiaomi, the $50 billion valuation provides a 'tranquilizer' for DeepSeek’s remaining engineers. It gives tangible, high-market value to employee stock options, ensuring that the lab’s top minds see a clear financial path that justifies staying the course as the company scales its compute-heavy operations.
