Hover to inspect recorded prices. Click to pin a point; click again to release. Drag between two points to measure the return over that span. Use arrow keys to move, shift with an arrow key to extend a span, Home or End to jump, and Escape to clear.

A price index: each company counts by its value at the previous close, public ones at market cap and private ones at their latest valuation moved by the secondary market. Dividends are not reinvested.

Values before Oct 2, 2026 are back-tested: the editors' list of that day, run backwards. They show how today's AI leaders performed, not what anyone could have picked then.
