ByteDance secured a $29.6 billion unsecured loan from nearly 30 banks on September 4, 2026, with the financing driven by the company's bet on AI development. ^[1] Anthropic announced on 2025-09-01 the release of the Fable 5.1 and Mythos 5.1 AI models, with Mythos 5.1 available only to authorized users under its Project Glasswing cybersecurity initiative and including distinct safeguards. ^[2] Anthropic filed for an IPO on 2025-06-01 and is expected to go public in fall 2025. ^[3] Anthropic said Fable 5.1 costs 25% less than Fable 5 for typical workloads because it reduces cache read pricing from $1 to $0.25 per million tokens, while standard input pricing remains $10 per million input tokens and $50 per million output tokens. ^[4] Chinese banks have subscribed to more than 60% of the total $29.6 billion loan amount. ^[5] The funds will mainly support ByteDance's AI-related plans, including projects outside China where the company is the offtaker for many data centers being built in Southeast Asia. ^[6] Three people with direct knowledge of the matter said the loan amount was increased from an initial target of $20 billion after an overwhelming response from lenders. ^[7] Lian Jye Su said Anthropic needs solid recurring revenue to maintain its valuation as it prepares for its IPO. ^[8]
