■ TOP STORY
The Trump administration has barred civilian US government agencies from using products or services from Chinese AI startup DeepSeek, whose affordable open-weight models are undercutting Silicon Valley competitors. The move signals escalating AI-sector protectionism amid US-China tensions.
► WHY IT MATTERS: Government procurement bans typically cascade into private sector pressure and set regulatory precedent for how the US will handle foreign AI tools.

AI cloud computing firm Nscale is in negotiations to supply computing power to Anthropic in a deal potentially worth $45 billion, according to sources familiar with the talks. The agreement would secure dedicated infrastructure for Anthropic's model training and inference.
► Multi-decade compute commitments signal AI labs are locking in resources amid fierce competition for GPU and energy capacity.

Chip design startup Tenstorrent closed a $1.5 billion funding round at a $6.2 billion valuation, choosing to remain independent after earlier acquisition interest. The round funds efforts to scale open-weight AI chip manufacturing as a challenger to Nvidia.
► Sustained VC backing for AI chip startups indicates serious investor belief that Nvidia's dominance can be fractured with sufficient capital.

Amazon and American Electric Power are evaluating plans for a 960-megawatt nuclear facility in Indiana using next-generation reactor design. The project would rely on unproven technology but could advance adoption of commercial small modular reactors.
► Tech giants' direct investment in nuclear energy signals that traditional grid capacity is insufficient for AI datacenter buildout timelines.

Chinese AI startup MiniMax released M3.1 Flash, continuing an aggressive pricing and performance race among Chinese AI labs that has driven inference costs toward zero. The move signals deepening competition in the open-weight model market outside US AI companies.
► Sustained Chinese price competition below Western margins could consolidate China's position in commodity inference while Western labs focus on premium reasoning models.
