The Rally Broadens Beyond Chipmakers

The S&P 500's industrials sector is seeing its price-to-earnings ratio climb close to tech-stock levels as investors chase exposure to the AI infrastructure buildout, even as debate continues over which chipmaker — Nvidia, AMD or Intel — is actually winning the AI chip race.

Bubble Warnings Multiply

SK Hynix's US share premium is being read as another AI bubble warning sign, while reports that Elon Musk is quietly turning to a fossil fuel to power his AI ambitions underscore the sheer scale of energy demand behind the buildout.

Winners, Workers and Wealth

Wages and productivity look set to diverge further as AI adoption and a falling labor share of GDP reshape economies across the rich world, and many white-collar workers say they're nostalgic for life before AI, worried about its effect on creativity and error rates. Commentators are meanwhile floating — some radical — ideas for spreading AI-driven wealth more broadly, given the riches so far are concentrated among a handful of companies.

Defence Tech and Regulatory Workarounds

Traditional defence giants are providing record backing for military start-ups building drones and autonomous systems, while separately, investors are reportedly using crypto exchanges' perpetual futures to get around China's controls on foreign access to its AI stocks.
