Cai Jianyong is a Chinese entrepreneur and billionaire, the Chairman of Lygend Resources & Technology, a major nickel trading and production company. His background is rooted in the commodity markets: he spent nearly a decade specializing in the complex business of commodities trading before founding his own company. He graduated from the Shanghai Institute of Building Materials Industry, providing him with a foundational knowledge of industrial materials and manufacturing.

Cai recognized the immense, specialized demand for nickel products, a critical component in the production of stainless steel and, increasingly, in electric vehicle (EV) batteries. This insight into the long-term, structural commodity needs of a modernizing global economy became the basis of his entrepreneurial vision and his ultimate multi-billion dollar fortune.

Cai Jianyong founded Lygend Resources & Technology in 2009, headquartered on the coast of the East China Sea in Ningbo. His strategy was built on mastering the supply chain of nickel products, spanning both trading and production. The company aggressively moved into the industrial side of the business, focusing its operations and investments in Indonesia, which holds much of the world's nickel resources.

Lygend's growth was rapid and strategic, positioning itself as a crucial supplier to the global stainless steel industry and the burgeoning EV battery market. The culmination of this expansion was the company's successful IPO on the Hong Kong Stock Exchange (HKSE) in November 2022, raising hundreds of millions of dollars to fund further Indonesian operations. Cai, who directly controls a massive stake (416.7 million shares directly, and 507 million shares through a holding company), secured his billionaire status as a dominant figure in the global nickel commodity chain.

Cai Jianyong's social impact is structural, stemming from Lygend's role in the global supply of nickel, a critical component for the manufacturing of sustainable technologies like electric vehicle batteries. His company's investment in Indonesia provides significant economic activity and employment in the resource-rich nation.

His career is a testament to the profitability of mastering the complex logistics and industrial challenges of the commodity supply chain. His wealth ensures continuous investment in the exploration and processing of essential industrial metals for the global economy.

Cai Jianyong maintains the traditional, professional style of a Chinese industrialist and commodities leader. His attire is consistently tailored, favoring dark business suits. His aesthetic is one of serious authority and stability, reflecting the capital-intensive and strategic nature of the global metals market.

Residing in Ningbo, China, his luxury is the immense security and financial reward derived from his dominance in the nickel supply chain. His life is defined by his commitment to mastering global trade and industrial production, with his wealth directly tied to the essential components of modern technology.
