What the chart can't show

Price speaks for demand. Filings speak for supply.

New shares reach the market in four ways. Rockseek reads the terms in the filings.

ATM · S-3 · 424B

A contract to keep selling, bit by bit, at market

With an effective ATM in place, the company can feed new shares into the market at any time.

Variable conversion · 8-K · 10-Q

Terms that turn the same principal into more shares

Notes and preferred whose conversion count moves with the share price. When the price changes, so does the number of shares that can appear.

Warrants · S-1 · 424B

The right to buy at a set price

When exercised, that many new shares come into being. The terms and quantities are in the filings.

Resale registration · S-1 · S-3

A registration that lets existing shares be sold

The moment a registration goes effective, those shares become supply that can reach the market.

Start 7-day free trial

7 days free — up to 10 lookups per day during the trial — then $39/month unless cancelled. Unlimited lookups begin with your paid plan. We'll show your next billing date before you confirm.

Prices exclude tax · VAT may apply depending on your region.

Pro plan: Unlimited lookups — no per-user caps, no counters. Cards refresh automatically when Rockseek detects a new SEC filing for that ticker. Refreshes draw on a system-wide daily capacity shared by all users; on unusually heavy filing days, your card always loads instantly from the latest completed analysis, and only the newest-filing refresh may briefly lag. This is a system capacity state, not a limit on your account.

Cancel anytime from your account page. Access remains until the end of the current billing period.

Cancel during the free trial and you are never charged. After payment, we refund in full if you request it within 7 days and have not used any paid features. Otherwise, fees already paid are generally non-refundable — except for periods when the service was unavailable due to our fault, and where applicable law provides otherwise (Terms, Article 7(5)). You can cancel anytime and keep access until the end of the current billing period.

FAQ

Start with your question.

Does Rockseek tell me what to trade?

No. Rockseek does not rank stocks, issue alerts or provide buy, sell or hold calls. You bring the ticker. Rockseek explains the filing-based supply structure.

Which filings does Rockseek read?

Rockseek reviews registration statements and amendments, prospectus supplements, 8-Ks and related offering, warrant and conversion documents.

How current is the card?

Each card shows its analysis date. Cards are not updated in real time — filings published after that date may not yet be reflected.

What happens when the filings are unclear?

Rockseek flags what could not be confirmed and lowers the evidence clarity. It does not fill missing facts with assumptions.

How is this different from a dilution tracker?

Many tools surface the filing data. Rockseek adds a consistent supply verdict, explains the mechanism in plain language and states the evidence limits behind the result.

How do I cancel, and what happens to my access?

Cancel anytime from your account page. Access remains until the end of the current billing period — you keep Pro until that date, and you are not billed again after it.

Do you offer refunds?

Cancel during the free trial and you are never charged. After payment, we refund in full if you request it within 7 days and have not used any paid features. Otherwise, fees already paid are generally non-refundable — except for periods when the service was unavailable due to our fault, and where applicable law provides otherwise (Terms, Article 7(5)). You can cancel anytime and keep access until the end of the current billing period. To request a refund, email support@rockseek.ai and we will process it after review. Separately from our policy, Lemon Squeezy — the payment processor and Merchant of Record — may issue a refund under its own criteria in exceptional situations such as a duplicate charge.

What if Rockseek can't analyze a ticker?

Some tickers do not have enough SEC filing data to complete a structural analysis. The card says so directly — nothing was positively detected, and nothing was ruled out. Rockseek does not fill the gap with assumptions.

Who processes payments?

Payments are processed by Lemon Squeezy as Merchant of Record. Rockseek does not store your card details.
