SiliconFlow raises 2B+ yuan Series B for its AI 'token factory'

The company calls itself a "token factory" — infrastructure that supplies the AI tokens every application needs to run. It now serves over 10 million users and 10,000 enterprise customers, processing trillions of tokens daily.
Why now? SiliconFlow's revenue has grown more than 10x year-on-year, and its overseas monthly revenue has reached millions of dollars. Third-party data backs its momentum: Gartner named it a representative vendor in its Global AI Cloud Market Guide, while IDC ranked it among the top four in China's public cloud MaaS market share — the only startup in that group.
On OpenRouter, a global token distribution platform, SiliconFlow's daily token consumption has ranked first among more than 70 suppliers for several consecutive weeks. Its plugins on the Dify Marketplace have surpassed 550,000 installations, placing it in the top five worldwide.
What could go wrong? The MaaS market in China is fiercely competitive. SiliconFlow is up against cloud giants like Alibaba Cloud and Baidu, which have deep pockets and captive customer bases. Margin pressure is a constant risk in a sector where providers routinely slash token prices to win share.
Geopolitics adds another layer of uncertainty. US export controls on advanced chips could constrain the computing power SiliconFlow needs to scale, especially as it tries to grow internationally.
The signal: This deal reflects a broader bet that AI infrastructure — not just the models or apps built on top — will be among the most durable businesses of the era. SiliconFlow's investor list spans energy, chips, cloud, and applications, signalling that players across the entire AI value chain see token delivery as a critical bottleneck worth funding.
It also highlights how quickly Chinese AI startups are scaling. With $2B in fresh capital and enterprise traction across state-owned enterprises, telecoms, and internet giants, SiliconFlow is positioning itself as the picks-and-shovels play for China's AI boom.
