# ChatGPT

**ChatGPT** is an AI assistant cited as an **incumbent holding predominant market share** — **64.5% of web traffic to LLMs as of January 2026**.

**Relevance to this source:** The authors argue ChatGPT rationally uses **auto-renewal** (e.g., on ChatGPT Plus) to defend its dominant position in a [[concept-variety-seeking-market|variety-seeking market]]. Like [[entity-netflix-d8|Netflix]], it exemplifies the incumbent × variety-seeking cell of the [[framework-renewal-strategy-matrix]] where auto-renew is correct — and a policy that challengers should not reflexively imitate ([[claim-competitive-position-dictates-default]]).
