What are the best free market trackers built from public filings?
The SEC publishes every registration, merger filing, private offering notice and 13F holdings report for free, and official bodies publish the data behind country risk. Free trackers turn those records into lists you can read in a minute. Below are 8 of them: 6 open trackers on Tamarly, rebuilt every hour with every row linked to its filing, and 2 official SEC tools for when you need to search the raw filings yourself.

Counts from each tracker on 31 October 2026. The company trackers are grouped by industry from the SEC industry code; the country ranking is grouped by region.
1. IPO pipeline
Companies that filed an S-1 or F-1 in the last 6 months, with the stage each has reached: filed, amended, priced or withdrawn. Companies whose shares already trade are left out. See where to track upcoming IPOs for free. It misses listings outside the US and how a new listing trades.
2. Mergers and acquisitions
Deals first filed with the SEC in the last 30 days, with the buyer, the target and the status, each linked to a deal page with every filing in order. See how to track new mergers and acquisitions. It misses deals between private companies with no SEC filing.
3. Private raises
Funding rounds of $25 million or more this week from news reports, marked as reported with the outlet, and every Form D notice, grouped by the industry the issuer filed. See how to read a Form D filing. Form D gives the amount sold, not the valuation or the investors' names.
4. Results calendar
When each of the 1,000 largest companies is expected to report, estimated from the spacing of its past results filings and grouped by industry. See how to see which companies report results soon. The dates are estimates; the company's own announcement takes precedence.
5. 13F changes
The companies with the largest rise and fall in institutional holders last quarter, grouped by industry. See how to see which stocks institutions bought. 13F holdings are a quarter-end snapshot filed up to 45 days later (SEC Form 13F FAQ).
6. Country risk ranking
Every scored country from 0 (lowest risk) to 100, with the week's movers, from sources such as the IMF World Economic Outlook (IMF WEO databases), conflict data (ACLED) and climate exposure (ND-GAIN). See how to assess country risk.
7. EDGAR full-text search
The SEC's own search across the text of filings since 2001 (SEC). Use it when you need every filing that mentions a phrase, a product or a competitor's name. It returns documents, not lists, so you read each one.
8. SEC Form D data sets
The SEC's quarterly files of every Form D notice (SEC), for when you want to analyse private offerings in a spreadsheet. They need cleaning before they are useful.
Which one should you start with?
Start with the question you have. To follow a sector, open the trackers for that industry; to find one filing, use EDGAR full-text search. More free options for filings are in the best free tools to search SEC filings.
Where does Tamarly fit, and where does another tool fit better?
The 6 Tamarly trackers are open to everyone without an account. A free account adds alerts on the companies, deals and countries you follow; paid plans start at $15 a month for the monthly reports and newsletter, $145 a month adds company, fund and deal pages, and $399 a month adds every catalogue report and the memo builder, with 7 days of the top plan free to try (Tamarly pricing). Tamarly shows no live prices, no analyst estimates and no investor names on private rounds; for those, paid market data terminals go further.
Open all trackers, free and updated every hour
Frequently asked questions
Are these trackers really free?
Yes. The 6 Tamarly trackers are open pages that need no account, and the 2 SEC tools are free public services (SEC).
How often are the trackers updated?
The pages are rebuilt every hour from the latest data. The IPO pipeline reads the SEC daily index every hour, country risk scores change once a week and 13F holdings change each quarter.
Do the trackers tell you what to buy?
No. They report what public records say. Tamarly holds no investment positions and gives research, never advice to buy, sell or hold.
