Stock: Getty ImagesThe first major labor fight over AI's windfall just played out in South Korea — and California is moving to explore the next one.Why it matters: Workers see the gap between AI-driven margin expansion and their paychecks. So do governors. Both will look to narrow it.This is not just a problem for big AI companies. Any company driving higher margins using AI could easily find itself in the crosshairs.What's happening:In Seoul: Samsung Electronics struck an 11th-hour deal with its union, averting an 18-day strike over AI profit-sharing.In Sacramento: Gov. Gavin Newsom ordered California to study universal basic capital — giving workers equity stakes in the AI economy. OpenAI and Anthropic have floated similar ideas themselves, assuming profits soar.Three things to watch:Unionized workforces strike first. South Korea, Germany and Japan are the leading edge. UAW and CWA are presumably studying the Samsung playbook now.Non-union workers will use the tools against you. Glassdoor, Blind and AI-built comp benchmarks make pay transparency unavoidable — and exploitable.Boards will get pulled in. Expect "AI productivity dividend" to become a 2026 proxy season demand from both labor and activist investors.What's next: Watch for Democrats to champion plans to share AI-related profits as part of their 2028 campaigns. This will resonate with MAGA leaders like Steve Bannon, too.📈 If you're a CEO or on a CEO's team: Ask to join Jim's new weekly Axios C-Suite newsletter.
