What changed in the AI trade, and why it mattered.
UBS flags a $35 billion problem for CoreWeave.
CoreWeave is a bellwether neocloud that has leaned heavily on debt-financed GPU buildouts to chase hyperscaler demand; a bank calling out a problem of this scale raises questions about the financing model that underpins the broader neocloud capacity race.
Beijing reportedly weighs letting Nvidia sales resume, and Chinese chipmakers sold off on the news.
A policy shift that reopens China to Nvidia would ease one of the biggest overhangs on Nvidia's addressable market, but it also threatens the domestic chip suppliers that had been filling the gap, explaining why those stocks fell even as the news reads bullish for Nvidia.
China and the US struck a $30 billion tariff cut and opened an AI dialogue.
Lower tariffs and a formal AI dialogue between the two largest players in the AI supply chain reduce a source of policy risk that has weighed on cross-border chip and hardware flows.

Nebius is raising AI compute prices starting October 1.
A neocloud raising prices rather than discounting signals that GPU capacity remains scarce relative to demand, supporting the read that compute shortages, not oversupply, are still the binding constraint across the trade.
TSMC's 2nm wafer capacity is reported to be tracking above earlier estimates.
More leading-edge capacity from the sole advanced-node foundry for Nvidia, AMD and Apple silicon eases a key bottleneck for next-generation AI chip supply.
Meta is building a 4,300-mile submarine cable.
Hyperscaler-owned subsea infrastructure points to continued heavy capital commitment to network capacity supporting AI workloads, a data point on the durability of hyperscaler infrastructure spend.
Texas Instruments raised its dividend 7%, extending a 23-year growth streak.
A steady dividend raise from an analog and embedded chip supplier is a minor data point on underlying cash generation but is not itself an AI infrastructure catalyst.
Networking and data center infrastructure names strengthened sharply over the week, while compute stayed strong but saw Broadcom slip and power stayed the weakest group.
The broad AI infrastructure group firmed up over the week, but the gains were led by networking and data center infrastructure catching up rather than uniform strength, with power lagging behind and neocloud names split, showing the advance is not yet even across every sector.
