Global artificial intelligence advancements in the first half of 2026 outpaced the ability to measure their effects, creating a significant gap in trust and attribution for brands and publishers.

This rapid, unquantifiable impact challenged traditional economic metrics, influenced consumer behavior in AI search, and led to a wave of legal disputes over content usage.

Consumer trust emerged as a crucial ranking factor in AI search, with 3 out of 4 consumers selecting top results unless a trusted brand appeared elsewhere, according to industry analyst Kevin Indig.

Software company valuations experienced a nearly 30 percent decline in the first six months of 2026, primarily driven by market perceptions of AI disruption rather than underlying company performance.

AI was cited in more than 87,000 job cuts through May 2026, though analysis suggested these layoffs often served as an explanation for pandemic-era over-hiring and efforts to enforce capital expenditure discipline, Challenger, Gray & Christmas reported.

Publishers initiated legal action against AI developers, including OpenAI and Microsoft, and search giant Google, alleging unauthorized use of their content and demanding greater control and transparency regarding AI training data.

The market share for AI agents saw shifts, with ChatGPT‘s dominance decreasing from 78 percent in July 2025 to 56 percent by July 2026.

Competitors Gemini and Claude gained market share during the same period, indicating a diversifying market for AI agent platforms.

The latter half of 2026 is expected to distinguish between AI model capabilities, referred to as ‘intelligence,’ and the permission for these models to act, known as ‘agency.’

Platforms and governments, including the U.K.’s Competition and Markets Authority, are anticipated to impose stricter controls over AI agents and their operational scope.
