Sharadar

What it is

Sharadar is a small US data publisher, founded in 2013, that builds its own fundamentals from SEC filings and reconciles each figure back to the filing it came from. For a decade it was known almost entirely as a dataset on Quandl and then Nasdaq Data Link — the SHARADAR/SF1 table code is still how most people search for it, and it is one of the publisher datasets that outlived the emptying of Quandl's free catalogue (see what replaced Quandl). On 4 October 2026 every Sharadar table on Nasdaq's API reported a refresh that same morning.

On 27 July 2026 it launched a direct, self-serve storefront for individuals: sign up, pay by card, get a key. The tables are the same ones Nasdaq sells — fourteen of them, from a securities master and fundamentals to end-of-day prices, insider trades and 13F holdings. The split between the two routes is the licence, not the data: sharadar.com sells only a Personal Use Licence, and Sharadar sends anyone buying for a firm back to Nasdaq.

Pricing

Three products and a bundle, each in three history lengths: 5 years, 10 years or full history. The 5-year column is the one in the big type, so the cheapest headline is misleading — the 29-dollar Bundle is five years of every table, and the full-history Bundle is 69 dollars a month or 499 a year. Bought individually at full history, Fundamentals, Prices and Investors are 39 dollars a month each; billed annually, Prices and Investors drop to 299 a year and Fundamentals to 399. Subscriptions can be upgraded, paused for up to three months, or cancelled at period end from the account page; payments already made are not refunded.

The free sample is the 30 Dow stocks over five years, and it is real data in the real schema, which makes it enough to write and test a pipeline before paying.

Commercial licences — any use by or for an organisation — are sold only through Nasdaq Data Link, whose product pages for these tables carry no price.

Data & coverage

US-listed equities only, including ADRs and Canadian issuers that trade on US exchanges, all end-of-day. Figures below are Sharadar's own, from its bundle page on 4 October 2026:

• Fundamentals (SF1): around 150 indicators for nearly 18,000 active and delisted companies, quarterly, annual and trailing twelve months, from January 1998. Updated at 17:30 and 23:30 ET.
• Stock prices (SEP): 21,000 tickers; fund prices (SFP): 10,000 ETFs, closed-end funds and similar. Open, high, low, close and volume are split-adjusted; closeunadj and closeadj (splits, dividends and spinoffs) let you derive the other two series.
• Insiders (SF2): 16,000 tickers and more than 200,000 insiders, from 2008.
• Institutional holdings (SF3, SF3A, SF3B): 13F holdings for 31,000 tickers and 13,000 investors from 2013, by position, by ticker and by investor.
• Reference tables: corporate actions (including acquisition cash and stock consideration, SIC and listing-venue changes), material events, historical S&P 500 constituents, daily valuation metrics, and a permaticker that survives ticker changes.

The figures do not quite agree across storefronts, or even across Sharadar's own pages. The launch post says fundamentals history runs from 1999, and Nasdaq's SF1 page, read the same day, still says more than 16,000 companies and up to 24 years. Check the series you need in the sample before relying on the first year.

Integrations

A REST API at api.sharadar.com returning CSV by default or JSON, with filters on ticker, date ranges and field lists, and a 10,000-row default page. Read the defaults: on the actions table from defaults to one year ago and to to the prior day, so a request with no date range returns one year of the history. For whole tables there is a bulk route that redirects to a zipped CSV at the history length you paid for, and Sharadar publishes PostgreSQL, SQLite and MySQL schemas for every table without a key. There is no first-party Python package for the direct API; on the Nasdaq route the tables work with Nasdaq's own client libraries.

Limitations

• Personal use only, strictly. The licence excludes every kind of entity, forbids sharing the data or derived data that reproduces it, and requires deleting all copies within 30 days of cancelling. Backtests, models and trade logs may be kept.
• The licence also forbids publishing an evaluation of the data's quality or fitness without Sharadar's permission — so independent reviews of its accuracy are scarce by design.
• End-of-day and US only. No intraday bars, no estimates or guidance, no options, no non-US listings.
• 99%, not 100%. Sharadar says the remaining gap in delisted coverage comes from malformed old electronic filings.
• No published commercial price. A small fund or a startup cannot see what Nasdaq will charge before a sales conversation.

Alternatives

SimFin is the nearest like-for-like — US fundamentals extracted from filings, with as-reported variants and bulk CSV — and its PRO plan carries a commercial licence for internal use, which Sharadar's direct store does not sell at any price. Norgate Data is the usual choice when survivorship-free prices and index membership matter more than statements. Financial Modeling Prep and EODHD cover far more markets at a similar price, with less attention to point-in-time history. For a guided route, see backtesting on survivorship-free data.
