Amazon reportedly got Anthropic's Fable 5 banned after $29B investment
Despite $29B in funding, Amazon allegedly tipped off Trump to block Anthropic's latest model.
Amazon has invested heavily in Anthropic — $4 billion in 2023 and an additional $25 billion in April — yet reportedly turned on its portfolio company. According to the Wall Street Journal, Amazon CEO Andy Jassy alerted Treasury Secretary Scott Bessent about security flaws in Anthropic's Fable 5 model, which led to the Trump administration banning the model outside the U.S. Anthropic claims the vulnerabilities were minor and common across frontier models. The real motive appears to be Anthropic's dual partnerships: after taking Amazon's infrastructure money, it committed $200 billion to Google Cloud and struck a deal with SpaceX for its Colossus data center. This infuriated Amazon, which is competing with Google on custom AI chips — Google's TPUs vs. Amazon's Trainium/Inferentia. Amazon sees Anthropic as a pawn in a larger chip war.
- Amazon invested $29 billion total in Anthropic but then reported security concerns to Trump officials, leading to Fable 5's ban.
- Anthropic committed $200 billion to Google Cloud and partnered with SpaceX shortly after receiving Amazon's latest $25B investment.
- The move is likely motivated by Amazon's rivalry with Google over custom AI chips (Trainium/Inferentia vs. TPUs) and Anthropic's choice to work with both.
