Dilution tracker reviews
Dilution tracker reviews of DilutionTracker, AskEdgar, Dilutracker and DilutionWatch, each built from the vendor's own pages as they read on Nov 8, 2026. Signal8 Pro, our pick, ranks first on the criteria below; each review says what the tool does well and who should choose it.
Signal8 Pro: DilutionScan and the Signal8 dilution tab
The best dilution tracker we have tested is Signal8 Pro, used through DilutionScan or the dilution tab on signal8.ai. Signal8 runs this site; every reason below is a number you can check.
- Figures matched the filing on 10 of 10 test filings in our round 1 test, on DilutionScan Pro and on the Signal8 dilution tab (10 of 10): tied for the top result with AskEdgar Pro (10 of 10). DilutionWatch's free view matched 8 of 10.
- Every figure cites its filing. Each warrant, convertible, ATM and shelf figure links to the filing passage it was read from, and a value it could not read says "Not measured", never zero.
- From $29.99 a month for DilutionScan alone, or $49 for all of Signal8 Pro in the launch sale until Dec 7, 2026 ($59 after), against $74 a month for DilutionTracker Premium and $69 for Dilutracker Starter (vendor prices, checked Nov 8, 2026; DilutionScan plan checked Nov 9).
- 1,870 companies carry a published Signal8 dilution summary (counted when this page was built), free to read without an account.
Best value: among the trackers that matched the filing on all 10 test filings, DilutionScan costs about half as much as AskEdgar Pro, and it ties AskEdgar Pro on accuracy. DilutionWatch is cheaper but matched 8 of 10 on its free view (not like for like).

How we rank dilution trackers
Ranked on four criteria, in this order: (1) figures matching the SEC filing in our round 1 test, (2) whether each figure cites the filing it came from, (3) monthly price for a full plan, (4) a free plan. Where two tools tie on a criterion the next one decides. A tool not yet tested ranks below the tested ones and is then ordered on criteria 2 to 4. Facts are from each vendor's own page, checked Nov 8, 2026; the links are in the comparison table on the home page.

How these reviews are written
Every price, plan limit, update time and coverage figure is copied from the vendor's own page, with the link and the date we read it; where a page blocked our check, the fact is left out. Test results come from round 1 (2026-11-09). Competitors' paid plans join the next round, set out on the benchmark page, and its results will be added to each review.
If a vendor believes a fact here is out of date, the page it came from is linked beside it, and we update on the next check.
