Story 1 · Corporate developments

AI-linked chip stocks sell off worldwide on funding and China concerns

Published: 2026-07-28
  • The global sell-off in semiconductor shares deepened on 28 July 2026.
  • South Korea's KOSPI fell far enough to trigger a temporary trading halt.
  • Samsung Electronics and SK hynix each dropped by more than 9 percent.
  • Drivers cited: doubts over the returns on AI infrastructure investment, and the rise of Chinese semiconductors and memory.
Why it matters

Markets are starting to question whether very large AI infrastructure investments are sustainable. Companies that use AI should re-examine cost structure and procurement risk.

Story 2 · Corporate developments

SK Group and NVIDIA strike a broad AI factory and memory partnership

Published: 2026-07-25
  • SK Group and NVIDIA announced agreement on a large-scale comprehensive partnership.
  • Its scope runs from AI factory construction to the joint development and supply of next-generation AI memory (HBM).
  • SK Telecom plans a two-gigawatt-class DSX AI factory built on NVIDIA Vera Rubin.
Why it matters

A long-term tie-up with a memory leader at the core of the AI semiconductor supply chain further strengthens NVIDIA's AI platform supply network.

Story 3 · Model releases

OpenAI begins rolling out Health in ChatGPT to US users

Published: 2026-07-23
  • OpenAI announced the start of the US rollout of Health in ChatGPT.
  • The feature connects securely with Apple Health and supported medical records.
  • It enables context drawn from medication details and test results, and OpenAI states the data is not used for model training or advertising.
Why it matters

Direct links between generative AI and personal medical data are spreading. Making healthcare utility and data governance work together becomes the central question.

Story 4 · Model releases

Anthropic announces its new flagship, Claude Opus 5

Published: 2026-07-24
  • Anthropic announced Claude Opus 5 and made it available the same day across all platforms.
  • Pricing is held at the same level as the previous model, and the model becomes the new default for Claude Max.
  • A control lets users switch the amount of processing between low, medium and high.
Why it matters

Delivering performance approaching that of higher-tier models at lower cost widens the range of cost-effectiveness options for enterprises adopting AI.

Overview

Three trends running through the period

TREND 01

Markets are repricing the AI build-out

Concern over the profitability of AI infrastructure investment is driving a broad global sell-off in semiconductor and AI-related shares.

TREND 02

The EU is easing burden, not obligations

The EU is lightening the operational load of its AI regulation while keeping key requirements, such as transparency obligations, on the original schedule.

TREND 03

Frontier models advance on two fronts

Lower prices with higher efficiency and expanded practical features, such as healthcare integration, are progressing in parallel.

Wrap-up

Three things to remember, and what to watch

Remember

  1. The AI hardware trade was marked down hard on 28 July, with a KOSPI trading halt and 9 percent-plus falls at Samsung Electronics and SK hynix.
  2. The supply side kept committing anyway: SK Group and NVIDIA agreed a partnership from AI factories to next-generation HBM.
  3. Frontier releases moved in two directions at once, deeper into regulated data at OpenAI and cheaper per unit of work at Anthropic.

What to watch next

  • Whether the doubts about AI infrastructure returns show up in capital expenditure plans, not only in share prices.
  • How the SK Group and NVIDIA agreement converts into delivered AI factory capacity.
  • How data governance commitments hold up as AI connects to more personal medical records.

This is a retrospective edition: only two items published within the preceding 48 hours met the adoption criteria, so the window was widened rather than padded.
