Hi! Maybe someone knows where can I find historical market capitalization or shares oustanding data for current and delisted shares? I'm looking for Nasdaq-100 data from 2004 to the present day

Market cap is a calculated value.
CODE:
double mktCapMillions = sharesOutstanding * averagePrice / 1000000.0;
So the question remains, which fundamental data provider do you use for the Shares Outstanding?

Personally, since I'm paying for an IQFeed subscription, I use IQFeed for getting the Shares Outstanding. It's not really a "real" fundamental data provider, but the basic subscription comes with a few fundamentals.

YCharts has Shares Outstanding, but the free version is really slow; I often disable it. The paid version is much faster. The paid versions of all the fundamental providers will be much faster. Are you in a hurry?

For a paid subscription, EODHD may be a good choice. If you don't want price data, you can get their fundamental-only data feed for around $20/mo. Well, that's apparently an old price.

Won't IQFeed provide several quarters worth of fundamental data only? If so, superticker is spot on re: EODHD. Here's the Wealth-Lab extension:
https://www.wealth-lab.com/extension/detail/EODHD

For companies delisted after 2018 they provide fundamental data (otherwise EOD only):
https://eodhd.com/financial-apis/delisted-stock-companies-data
https://eodhd.com/financial-apis/stock-etfs-fundamental-data-feeds

Their $20 plan does not cover fundamentals so you will need the Fundamentals plan that costs $59.99/month:

Historical market cap (and especially for delisted stocks) is a bit tricky, since free sources usually don’t keep complete data. A few options you can explore:

Official filings – SEC EDGAR has historical 10-K and 10-Q filings with share counts, but it’s manual work to piece together.

Commercial datasets – CRSP and Compustat are the gold standards for full survivorship-bias-free history (including delisted stocks), but they’re subscription-based.

Alternative free/low-cost sources – Yahoo Finance and Nasdaq sites can give you shares outstanding for current listings, but usually not for delisted names.

If you’re specifically after Nasdaq-100 history (2004–present), you may want to check out https://finjovi.com which provides structured historical data that’s easier to work with compared to scraping filings.

The current WL Yahoo event provider (I'm running WL Build 133) does not scrape the Yahoo website for shares outstanding. I suppose you could put that in as a WL feature request.

Some of the brokers' Quotes pages include market cap or shares outstanding. But you'll need to scrape those pages to put that info into WL.
