Today: the five AI headlines of the day → and the AI Wiki

What a claim record is How to read this page

One statement, bounded on purpose

The headline is a single claim that a named source supports. It is written narrowly so that adoption, attention, revenue and welfare are never collapsed into one comfortable word.

The three sections below the fold

What this does not establish is the boundary of the evidence. Counterevidence & uncertainty is what argues the other way. What would change the reading is the observation that would move it. A record missing any of the three is incomplete, not merely brief.

Primary routes are checkable

Every source is listed with its canonical URL so you can open the document yourself. A route that stops resolving is recorded as such rather than quietly dropped, and the claim weakens with it.

MWITA-AISO-2026-002 · Evidence A · P1

Google AI Overviews reduced daily traffic to exposed English Wikipedia articles by about 15% relative to matched articles in language versions not yet exposed.

D01 · Marketing, Brand & Revenue Systems D17 · Distribution, Discovery & Audience D19 · Measurement, Experimentation & Economics

What this does not establish

Wikipedia traffic is not general publisher CTR, conversion or revenue; language versions differ structurally.

Counterevidence & uncertainty

The result weighs against pure complementarity between AI summaries and source traffic; smaller-publisher and revenue effects remain open.

What would change the reading

Track replication, revised versions, denominators, confidence intervals, platform changes and deployed commercial outcomes.
