SpaceX and Tesla filed notice in Grimes County, Texas for TERAFAB, a joint semiconductor and computing facility projected to cost $119 billion overall with $55 billion required in early phases. The plant would manufacture custom silicon for Tesla's FSD and Optimus programs plus SpaceX orbital datacenters, using Intel's 14A process at a site near Gibbons Creek Reservoir that could scale to terawatt computing output; Musk noted on May 6, 2026 it is one of multiple locations under review as the county considers tax abatements.

The Circuitry is a passion project I've always wanted to build, and I love the work behind it.
Running it costs real money. APIs, hosting, time. To keep improving the site and growing this into something useful for everyone, those costs have to be covered.
Any contribution is appreciated. If not, no pressure. Thanks for reading.
GlobalFoundries signed a multi-year US$2 billion agreement with TSMC on October 8, 2026 to manufacture silicon interposers at its Malta, New York fab. The deal creates the first US-based source of silicon interposers for TSMC's CoWoS advanced packaging ecosystem.
SpaceX has agreed to acquire Grain Management's nationwide 800 MHz spectrum portfolio, which it says will pave the way for Starlink Mobile to become a major US mobile carrier. The deal needs FCC approval, and financial terms were not disclosed.
Anthropic has launched the Anthropic Cyber Mission to support defenders of critical infrastructure and open-source software with models, engineers, and tools. The initiative starts with the Critical Infrastructure Defense Program and free OSS Scanner amid ongoing challenges in verifying and fixing vulnerabilities.
Anthropic released Claude Haiku 5.5, its cheapest and fastest small model, at $0.10 per million input tokens and $0.50 per million output tokens for prompts up to 100,000 tokens. Anthropic says it costs around 75% less to run than Haiku 4.5 on average and scores far higher on its benchmarks.
OpenAI released 722 mathematical manuscripts, grouped into 372 result families, produced by an unreleased internal model. The papers are on GitHub, with Lean formalizations for many but not all of them, and OpenAI warns some unformalized results could have issues.
