AI Infrastructure:
What changed in the AI trade, and why it mattered.

Amazon and utility AEP will explore up to 960MW of small nuclear reactors in Indiana to power AI.
Hyperscalers are tying their data center growth to dedicated, long-term power supply, which pulls in the power producers and equipment makers behind it. Amazon closed 5.0% higher on the day, so the market took the news well.

Schneider Electric completed a €6.0 billion share sale, and ABB reported Q3 results and agreed to buy a controlling stake in a Mitsubishi Electric unit for $495 million.
The makers of electrical gear that data centers depend on are raising money and buying capacity, which shows how much they expect demand to grow. Schneider's raise brings new shares, while ABB's deal adds to its business. The read on the group is mixed, and the wider data center equipment group weakened over the week.

Data center builders are lining up land and power: an Alcoa smelter sold for $315 million and a temporary gas plant proposed in Cardiff.
Getting power and sites is now a main limit on building AI capacity, so developers are buying industrial sites and turning to on-site generation. Alcoa selling its New York smelter to a data center developer shows industrial land being converted. This points to the power and data center infrastructure parts of the chain.

Money keeps flowing into AI chips: Tenstorrent raised $1.5 billion and Nvidia plans to back four German startups.
Tenstorrent's $6.2 billion valuation shows investors still fund challengers to the leading AI chip suppliers. Nvidia's nearly $10 billion European pledge shows it putting its own money into the ecosystem around its chips. Both bear on the compute part of the chain.
