Alibaba shares hit 16-month low on Anthropic accusations as DeepSeek raises $7.4B

Alibaba's Hong Kong-listed shares dropped to their lowest level in 16 months after Anthropic publicly accused the company of running the largest-yet campaign to extract Claude's capabilities. The reputational hit compounds investor unease about the regulatory and geopolitical risks facing Chinese AI players seeking to compete with US frontier labs.

The same news cycle, however, showed the strength of China's low-cost AI ecosystem. DeepSeek closed its first official external round at $7.4 billion (50 billion yuan) and a $50+ billion valuation, with backers including Tencent, CATL, and China's National AI Industry Investment Fund. Founder Liang Wenfeng invested roughly $3 billion personally and retains nearly 90% of voting control, an unusually concentrated structure for a round this size.

DeepSeek made its 75% V4-Pro price cut permanent and announced plans to double its workforce across 27 technical roles spanning data and development engineering. The combination — fresh capital, permanently slashed prices, aggressive hiring — reads as deliberate disruption of US model economics, and the community flagged an unusual investor 'no-poaching' pledge as a sign of how strategic the round is.

The contrast is the week's quiet subtext: while one Chinese giant is on the defensive over alleged IP theft, another is being richly funded to compete on cost. Watch whether DeepSeek's V4 line (its V4 Flash already a Reddit favorite among budget users) continues pressuring API pricing across the industry, and whether Alibaba's stock stabilizes once the Anthropic story fades.
