Jack Ma-backed OceanBase, a Chinese database company, is raising up to $443 million（約710億円） to fund its expansion into AI database services and operate more independently. Originally built to manage Ant Group's transactions, OceanBase now serves thousands of Chinese clients and reported more than $200 million（約320億円） in annualized revenue in 2026, up 70% year-over-year. The funding will support its push into AI analytics and international expansion as database systems become a critical layer connecting enterprise data with AI models.

Beijing OceanBase Technology Co. is in discussions to raise about 2 billion to 3 billion yuan ($295 million（約470億円） to $443 million（約710億円）) in Series A funding to operate more independently and expand into AI database services.
Why it matters
OceanBase, originally built to support Ant Group's internal database needs, now handles half a million transactions per second during major Chinese sales events and has become a critical infrastructure layer connecting enterprise data with AI models. The company had more than $200 million（約320億円） in annualized revenue in 2026, up 70% from the previous year, and holds the largest market share in China for distributed databases as of 2025.
What to watch
OceanBase is benchmarking itself against Databricks, which reported it was on track to generate $5.4 billion（約8600億円） in annual revenue in February; the startup is expanding beyond its predominantly Chinese client base (Industrial & Commercial Bank of China, China Mobile) into Southeast Asia, Japan, India, and Latin America.
OceanBase, a Beijing-based database company backed by Jack Ma, is seeking to raise about 2 billion to 3 billion yuan ($295 million（約470億円） to $443 million（約710億円）) in Series A funding. The capital will enable the company to operate more independently from Ant Group and fund its expansion into AI database services, according to people familiar with the matter.
The company's roots trace back to 2010, when it was built to support Ant Group's internal database management needs. OceanBase has since become the backbone of Ant's transaction processing, handling half a million transactions per second during major shopping events such as Singles' Day in China. Today, the company serves thousands of clients, predominantly based in China, including Industrial & Commercial Bank of China Ltd. and China Mobile Ltd., as well as clients in Southeast Asia, Japan, India, and Latin America.
OceanBase's financial performance has been strong. In 2026, the company generated more than $200 million（約320億円） in annualized revenue, representing 70% growth from the previous year. The company is now focusing on bolstering its AI analytics capabilities, moving beyond structured data to handle semi-structured and unstructured data such as videos. This shift reflects a broader industry trend: database managers are becoming a critical infrastructure layer that connects enterprise data with AI models and agents.
OceanBase views Databricks, the San Francisco-based data analytics company, as a key benchmark. In February, Databricks said it was on track to generate $5.4 billion（約8600億円） in annual revenue, with $1.4 billion（約2200億円） coming from AI products. Databricks is also raising new capital from investors led by Coatue Management at an $188 billion（約30兆円） valuation, according to people familiar with the matter. In the competitive landscape, OceanBase competes against Huawei Technologies Co. and Tencent Holdings Ltd., and held the largest market share in China for distributed databases in 2025, according to IDC. Globally, other tech firms including IBM, Snowflake Inc., and Amazon Web Services Inc. are also building out database management systems.
OceanBase's funding push reflects the growing importance of database systems as infrastructure for enterprise AI. Born in 2010 as an internal solution for Ant Group's transaction processing—the company has demonstrated its ability to scale to half a million transactions per second during peak demand events like Singles' Day—OceanBase has evolved from a specialized backend into a platform serving thousands of clients across China's largest financial and telecommunications institutions. The company's 70% year-over-year revenue growth signals strong market traction, and its expansion into semi-structured and unstructured data (video, for example) positions it at the intersection of traditional database management and modern AI workloads.
OceanBase's benchmarking against Databricks is telling: Databricks, a San Francisco-based data analytics firm, reported being on track to generate $5.4 billion（約8600億円） in annual revenue in February, with $1.4 billion（約2200億円） from AI products alone. By seeking comparable capital at a much earlier stage of its international expansion, OceanBase is signaling confidence in a global market for AI-native database infrastructure. The company holds the largest market share in distributed databases in China as of 2025, but its move into Southeast Asia, Japan, India, and Latin America suggests ambitions to replicate that dominance in regions where Chinese tech firms are increasingly competing with US incumbents like Amazon Web Services, IBM, and Snowflake.
