OceanBase seeks up to $443M for AI database expansion

Ant Group's OceanBase is seeking up to $443 million in Series A funding to operate more independently and expand into AI database services, as Chinese enterprise tech companies race to build the infrastructure layer connecting corporate data with artificial intelligence models.

Beijing OceanBase Technology is in discussions with investors to raise about 2 billion to 3 billion yuan ($295 million to $443 million), according to people familiar with the matter. The company, which holds the largest market share in China's distributed database market, had annualized revenue exceeding $200 million in 2026, up 70% from the prior year.

"Database managers are becoming a critical layer of infrastructure that connects enterprise data with AI models and agents," one person familiar with the company's strategy said. OceanBase is looking at San Francisco-based Databricks as a benchmark — the US firm said in February it was on track to generate $5.4 billion in annual revenue, including $1.4 billion from its AI products.

Originally built in 2010 to support Ant Group's internal database management, OceanBase underpins the fintech giant's ability to process half a million transactions per second during Singles' Day sales events. Its core product is an open-source distributed relational database used by Alipay. The company is now bolstering its AI analytics capabilities through Lakebase, a platform that supports vector search alongside unstructured data such as documents, images and video — a critical capability for enterprises building retrieval-augmented generation applications.

The Competitive Landscape

OceanBase competes directly with Huawei Technologies and Tencent Holdings in China's distributed database market, where it held the top position by market share in 2025, according to an IDC report. Globally, the company faces International Business Machines, Snowflake and Amazon Web Services, all of which have been building out database management systems with AI capabilities.

The company's thousands of clients are predominantly Chinese, including Industrial & Commercial Bank of China and China Mobile, according to its website. OceanBase has also started expanding into Southeast Asia, Japan, India and Latin America, seeking to replicate its domestic success in markets where cloud adoption is accelerating.

The Ant Group Separation

OceanBase set up an independent board and employee share-based rewards program in 2024 to pave the way for an eventual spinoff from Ant Group. The shareholder restructuring left the database company no longer wholly owned by Ant, with its own governance structure and incentive plan. Alibaba Group Holding, founded by billionaire Jack Ma, owns about a third of Ant Group.

Ant Digital Technologies, the enterprise solutions arm of Ant, is also exploring a separate fund-raising effort, though details have yet to be determined, one person familiar with the matter said.

Investor Implications

The Series A round values OceanBase against a backdrop of surging demand for AI infrastructure. Databricks is seeking capital from investors led by Coatue Management at a valuation of $188 billion, people familiar said in July. While OceanBase operates at a fraction of that scale, its 70% revenue growth rate and dominant position in China's distributed database market suggest significant upside if it can capture a share of the AI database opportunity. The company did not disclose its valuation target for the Series A round.
