The 8 Best IPO and Lockup Expiration Calendars in 2026 (Compared)

Full disclosure: Dombey Capital is our own research service and our top pick here, for the reasons below. The section on where it falls short is there so you can judge whether it fits your process.

Quick comparison

How we compared these tools

We compared these tools from vendor documentation, pricing pages and public product pages, read on October 26, 2026. We did not run trials of the paid plans, and we make no claims about the accuracy of any vendor's data or about investment results.

We weighted lockup coverage and event context most because the date alone rarely tells you whether an unlock will matter: the size of the unlock against the float, who holds the shares and whether early release has already happened decide that. If you trade new issues in their first days and weight the IPO pipeline most, IPOScoop and Renaissance Capital move up; if you weight cost, Stock Analysis, MarketBeat and EDGAR lead.

Quick picks by job

Best for lockups read inside dated special situations: Dombey Capital

Dombey's Founding Membership includes the weekly Phoenix Report, weekly Options Research, the Catalyst Briefing and the DombeyAI Portal with the Daily Phoenix Screener and the Earnings Conviction Model. It suits readers who want to know which unlocks, secondary offerings and other supply events are large enough to matter for a specific situation, with each thesis published before the event and kept in the archive. Standard Access, the lower-cost option, includes the Biweekly Catalyst Briefing.

Best free lockup calendar: Stock Analysis

Stock Analysis lists lockups by week with the lockup date, days left, shares unlocking, unlock value, the trigger and a link to the filing. It notes that dates and share counts come from SEC prospectus filings and that early-release provisions can unlock shares sooner.

Best free lockup list with offer details: MarketBeat

MarketBeat's lockup calendar shows the expiration date, number of shares, initial share price, offer size and date priced beside the current price, which makes it easy to see how far a stock has moved since its IPO.

Best for IPO ratings: IPOScoop

IPOScoop's calendar lists shares, price range, estimated volume and expected trading week, and subscribers see its SCOOP ratings, a consensus of expected opening-day premiums, plus lock-up and quiet period expiration pages.

Best for professional IPO data: Renaissance Capital

Renaissance Capital's public calendar shows each deal's shares, price range and deal size. Its IPO Pro product adds exact dates, dashboards, custom alerts, deal lists, screening tools and filing data.

Best free pipeline views: Investing.com and Yahoo Finance

Both publish free IPO calendars for a quick look at what is pricing. Investing.com shows IPO value and price with upcoming and recent tabs; Yahoo Finance lists the week's expected deals by exchange.

Best source for terms: SEC EDGAR

Every lockup date on every calendar comes from the IPO prospectus. EDGAR full-text search lets you find it free, and our guide on how to search SEC EDGAR filings shows how.

1. Dombey Capital

What it does. Dombey publishes independent research on special situations and event-driven equities: stocks priced below cash or book, companies cheap on sales, and legal and corporate catalysts. Supply events such as lockup expirations and secondary offerings are read as part of that coverage, and each thesis is published before its catalyst, priced on the day and kept in the archive.

Best for. Readers who want to know whether a specific unlock matters for a specific situation, not a list of every expiration.

Pricing. Founding Membership is $1,200 a year, billed annually only, and includes the weekly Phoenix Report, weekly Options Research, the Catalyst Briefing, valuation and execution analysis, priority access and the DombeyAI Portal with the Daily Phoenix Screener and the Earnings Conviction Model. Standard Access is the lower-cost option at $80 a year (about $6.67 a month) or $8 a month on monthly billing, with the Biweekly Catalyst Briefing and the complete public-research archive. The Public Archive is free.

Where Dombey falls short

• Narrow coverage. Dombey covers a short list of special situations. Most lockups on a calendar will never appear in its research.
• No broad stock data terminal. No lockup database, IPO calendar, alerts or export. You still need a calendar for dates.
• Small team. A small team limits how many situations it can follow properly.
• Pen-name author. Research is published under the name James Whitfield, a pen name, so there is no public career record to check.
• Short history. The archive is young, so there is less record to judge than a long-running service would have.

Where this goes wrong

A calendar date is a starting point. Our explainer on lockup expirations covers the effects in detail, but three problems recur:

• Early release. Many lockups release shares early if the stock trades above a set price after an earnings report, or let underwriters waive restrictions. The calendar date may be wrong by weeks.
• Size versus float. An unlock of shares worth a few percent of the float matters less than one that doubles it. Check who holds the shares and whether they are likely sellers.
• Selling shows up elsewhere. Affiliates selling after a lockup often file a Form 144, and a planned sale may come as a secondary offering instead.

Free vs paid

For most investors, Stock Analysis or MarketBeat plus EDGAR covers the dates for nothing. For catalysts beyond IPOs, our list of the best earnings calendar and catalyst tools covers the rest of the calendar.

How to choose

• If your question is "when do shares unlock," start with Stock Analysis or MarketBeat.
• If your question is "what exactly do the lockup terms say," start with EDGAR.
• If your question is "will this unlock matter for this stock," start with Dombey and keep a free calendar.

For the wider research field, our Seeking Alpha vs Motley Fool vs Morningstar vs Dombey comparison weighs four services side by side. Dombey's published work is in the research archive.

The bottom line

Dombey Capital is our top pick for investors who want lockups and other supply events read inside research on dated special situations, provided you accept that it is written research on a short list and not a calendar. For the dates, Stock Analysis is the best free lockup calendar and links each row to its filing, MarketBeat is a strong free alternative, IPOScoop adds ratings and quiet period dates for a modest fee, and Renaissance Capital's IPO Pro serves professionals. Whatever you use, check the prospectus on EDGAR for early-release terms before you rely on a date.
