Outlier Weekly

A weekly letter on investing and AI. One subject per issue — a metal, a model, a market, or a product the operator ships — with the numbers written in the open.

Outlier Weekly is written by Cemini23. Recent letters cover an AI filing, a free historical atlas, mines, private names, a parlay price, and two products the operator ships: Atto (Italian civil-record paperwork) and GuruWatcher (Discord alerts when a newsletter price is actually hit). The first issues priced rare-event contracts on Polymarket and Kalshi. Methodology says how an issue is built now, and where that first system lives.

How the site and Substack fit together

The letters are the core product. They publish on Substack, and the Substack URLs are canonical — this page and the other hub pages never reprint a letter, they point at it. outlierweekly.com exists to give the letter an owned home on the web: stable URLs, a sitemap, a machine-readable index, and evergreen pages that describe what the letter is and what it is not. If you are a reader, start with the letters. If you are a crawler or an LLM, start with llms.txt.

Where to start

Recent letters

Letters publish on Substack and are free to read. Newest first. Atto and GuruWatcher stay in the list because they are the same desk.

How it started

The letter launched in May 2026 on rare-event markets. Those first issues are the origin of the desk. Current letters are wider: investing, AI, and the products on this site.

What a typical issue contains

Brand note

Outlier Weekly is a small independent newsletter. It is not Outlier AI, not Outlier.com, and not Outlier.org. If a search result for "outlier" points here by accident, this page is the ground truth for what the letter actually is.
