S&P 500 Sector Weights Today

Each GICS sector’s share of the combined market value of the S&P 500 companies, %, latest trading day

Information Technology leads at 36.1%
Current·Data to Oct 22, 2026

Plays the chart through its history. Pauses are where a new leader takes first place.

Calculated by Palanor: each company’s closing price × its current share count, from licensed closing prices and SEC filings, summed by GICS sector over today’s S&P 500 members. Applying today’s members and sectors to past dates leaves out companies that have since left the index (survivorship bias). Not S&P Dow Jones Indices’ official, float-adjusted sector weights.

How much of the S&P 500’s value each of the eleven sectors makes up, ranked.
