Market-cap change uses historical capitalization records. Share-price returns are a different series — they can diverge when the share count changes. Those returns are not a CAGR until you pick a start value, an ending value, and years. CAGR calculator. Market cap vs. stock price.
Year-end values and the chart both come from historical market-cap records, not from applying today's share count to past prices. Latest historical observation October 2, 2026. Ranking headline cap is the snapshot figure as of October 2, 2026.

Arch Capital Group Ltd.'s ranking market cap is the provider-reported capitalization on the same snapshot as the rest of this site, with a share price of $93.60 as of October 2, 2026.

Live shares outstanding are not on the quote used for price, so this page does not invent a current share count. Shares outstanding vs. float.
The latest annual report (FY 2025) used a weighted-average 369,000,000 shares. That figure is an average for the year, not the live count in the market-cap formula.
Multiplying the latest price by those FY 2025 weighted-average shares would give about $34.54B. The ranking uses the provider's reported market cap instead, which reflects a current share count rather than that annual average.
