MetaX Weekly AI Trend Report Week 31 2025 -- Astronomical Investment and Full-Scale War by Big Tech Companies to Seize AI Technology Hegemony, Fundamental Innovation in Technology Models and Hardware Infrastructure Along with Rapid AI Productization: The competition among companies to seize AI technology leadership is becoming more intense. OpenAI achieved annual revenue of 12 billion USD proving high financial growth, while simultaneously negotiating new conditions with Microsoft to continue using technology even after artificial general intelligence declaration. Competitor Anthropic is also negotiating large-scale fundraising nearly tripling its corporate value in 4 months, while expanding influence into healthcare. Meanwhile big technology companies are also busy. Meta recruited former ChatGPT co-founder as chief scientist and is accelerating superintelligence research, and this success in AI technology led to advertising revenue and stock price increases. Apple CEO Tim Cook also announced significantly expanding AI technology investment and being open to related company acquisitions, but stated that key AI features will be developed internally. The hardware infrastructure transformation: AI training and inference are driving fundamental changes in data center architecture -- custom ASICs are replacing general-purpose GPUs for specific workloads; liquid cooling is becoming standard as power density increases; the power and water consumption of large AI deployments is creating new infrastructure constraints and environmental considerations.
