# Anthropic launches two new fellowships

Full title: Anthropic opens applications for STEM Fellows and Conceptual Reasoning Fellows to help Claude reason about the hardest problems in science, philosophy, economics and law

On Oct 15, 2026 Anthropic opened applications for two fellowships: STEM Fellows (science and engineering) and Conceptual Reasoning Fellows (philosophy, cognitive science, economics, policy and law). Fellows spend four months at Anthropic from January 2027 "working to help Claude reason well about some of the hardest problems in those fields"; the deadline is Oct 28. The X announcement passed 1.19 million views in a day.

## Key facts
- Four months at Anthropic starting January 2027; application deadline October 28, 2026
- STEM Fellows: science and engineering. Conceptual Reasoning Fellows: philosophy, cognitive science, economics, policy and law
- The STEM Fellows Program already existed: its first publicised result, Claude Mythos 5 designing more efficient quantum circuits (Andi Gu, with Harvard), was announced the next day
- X post reach: ~1,195,000 views (fxtwitter, Oct 16)

## What happened

Anthropic announced the fellowships on X with links to two job postings. The Conceptual Reasoning track is notable: it recruits
philosophers, economists and lawyers to improve how Claude reasons, alongside the existing science-and-engineering track.

## Why it matters

One of Anthropic's most-viewed posts of the week. It shows the lab paying domain experts to work directly on Claude's reasoning in
fields where answers are hard to check, beyond maths and coding.
