SpaceX has designated AI as the primary driver of its future in its S-1 filing preceding an expected IPO, estimating a $26.5 trillion addressable market after absorbing xAI to oversee Grok. The ambitious pitch arrives as Grok substantially trails ChatGPT, Claude, and Gemini in both consumer paid usage and corporate adoption.

The S-1 filing states that SpaceX possesses “the largest actionable total addressable market in human history,” with AI accounting for the majority at an estimated $26.5 trillion.
Musk described xAI prior to the merger as “the smallest of the AI companies” during court hearings related to his OpenAI lawsuit.

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.
SpaceX is seeking $40 billion in debt financing led by Apollo Global Management to buy Nvidia AI chips, with talks still early and a possible 2027 close. The move highlights the scale of capital required for AI infrastructure expansion across Musk's companies.
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.
Meta and Microsoft are cutting employee use of Anthropic’s Claude AI and directing staff toward their own coding tools, The Information reported. The changes reflect tighter internal AI budgets while customer access to Claude through Microsoft platforms continues to expand.
