August 4 · Tuesday’s strongest signals. Three minutes.

⚡ Absolute Top Alerts

Five developments changed the stakes for power, trade secrets, household security, AI policy, and memory supply.

Lead · Aug 3 · Funding
Valar raises $1B for nuclear reactors as AI’s power crunch deepens

Valar Atomics confirmed $1 billion in equity plus a $200 million credit line. The startup wants to manufacture compact reactors repeatedly rather than build each plant as a bespoke megaproject.

The stakes: Its Nvidia-linked plan includes a waterless 30MW AI data center. Compute capital is now reaching beyond chips and buildings into the power plants meant to keep them running.

The firm expects much of the debt to mature in three to five years, matching chip lifespans, and to exceed 5% of the US high-grade index. Caveat: this is one desk’s forecast, not committed issuance.

Aug 3 · Coding-agent benchmark
Coding agents lose 7.7 points when the user edits too

SWE-Touch injects plausible user changes into SWE-bench Verified tasks. Across nine models, average resolution fell 7.7 points—evidence that workspace coordination is a capability of its own.
