What is the US labor share today?

Roughly 56% to 60% of national income depending on the measure, down from the low 60s two decades ago and stable since the mid-2010s.

Why does a falling labor share matter for stocks?

Because the other side of the split is profits. A lower labor share with the same output means higher margins for the companies that own the automating capital — and lower demand from the households that lose the wages, which is the business-cycle risk the scenarios leave out.

Which scenario is Closelook’s base case?

None. The paper makes no prediction and neither do we; we track the levers — automation share, cognitive unemployment, capital income — against what the tape is paying for.

Glossary term

Labor Share

The fraction of a country’s income that goes to workers as wages and benefits rather than to owners of capital as profits, rent and interest. Around 56% to 60% in the United States for decades; the number AI scenarios move most.

What it means

Add up everything an economy earns in a year and split it between labor (compensation of employees) and capital (corporate profits, proprietors’ income, rent, interest). The labor share is labor’s part. It fell from about 64% in the early 2000s to the high 50s and has been stable since; economists argue over how much of the fall is technology, globalisation, market power and measurement. A falling share with rising output means the gains accrue to owners.

For AI the share is the cleanest single number for “who gets paid”: automation that replaces cognitive work lowers the labor share directly, while any productivity gain raises total income.

Why it matters for the AI trade

Anthropic’s economic-scenarios paper (September 2026) gives three 2030 economies with labor shares of 59.4%, 56.1% and 45.2%: modest, substantial and extreme automation. In the extreme case GDP rises 32% above the no-AI path while the labor share falls 14 points and cognitive-sector unemployment reaches 18%. The capital that earns the difference is the AI build-out — the same data centres, chips and models the Rubin and Agentic Winners indices hold. The share is the bridge between the paper and the tape.

How Closelook uses it

The Three Futures read walks through the scenarios and the omission — who owns the capital income — and the digital labor economy and SaaSpocalypse entries follow the cognitive wage bill into seat-based software revenue.
