Overview
The consumer AI assistant market is concentrated at the general-purpose default: ChatGPT and Gemini account for 83.6% of reported primary choice in a June 2026 survey of 1,999 US adults who were aware of and had used at least one assistant during the previous month. This series then tests task routing, multihoming, audiences, payment, trust, privacy, and upstream production. The evidence shows live competitive margins, but not durable closure; BIS firm geography and investment do not establish consumer control.
Learning outcomes
- ChatGPT and Gemini account for 83.6% of reported primary choice among surveyed US AI users, establishing a concentrated default layer.
- About 43% intentionally route different task categories across platforms, so primary choice does not establish exclusive use or durable closure.
- Task fit, user composition, and personal or institutional payment can give smaller platforms valuable positions without proving a takeover.
- Trust and privacy can support challenger growth, but experience, policy knowledge, credibility, task sensitivity, and price condition their effect.
- Upstream AI production is concentrated and specialized, yet its link to consumer-assistant control remains unestablished.

PlansFAQ
Is the consumer AI assistant market closed?
It is concentrated at the general-purpose default, but durable closure across tasks, users, trust, privacy, payment, and production is not established.
Where can smaller AI assistants compete with ChatGPT and Gemini?
Smaller assistants can win recurring task niches, intentional multihoming, distinct payment channels, or trust- and privacy-sensitive occasions, but the evidence does not establish durable market-wide pressure.
How do trust and privacy affect consumer AI-assistant choice?
They can support trial, repeated routing, or payment when experience, policy knowledge, credible guarantees, task sensitivity, and price align; the evidence does not show mass switching.
Does upstream AI concentration prove consumer-assistant control?
No. The BIS study maps selected large AI-producing firms across 32 economies and five layers, but does not link producer geography or investment to a particular assistant’s consumer share or control.
