Rule 144 vs Rule 144A: Key Differences Explained
Two SEC rules for reselling shares that were never sold to the public. Who can buy, how long you wait and what each means for an employee or investor.
- Securities law
Rule 144 vs 144A comes down to who buys your shares. Rule 144 lets you sell restricted shares to anyone on the public market after a holding period. Rule 144A lets you sell them right away, but only to large institutions. Employees and early investors in a company that goes public use Rule 144. Banks and funds trading private bonds use Rule 144A.
If you hold private-company shares, Rule 144 is the rule that will matter to you. It decides when your shares can reach a stock exchange. Rule 144A works in a market built for institutions with at least $100 million invested. Individuals cannot buy there.

Rule 144 vs Rule 144A: What Is the Main Difference?
The table compares the two rules on definition, who can buy, holding period, who uses each, legal and tax treatment, risk, liquidity and a typical example.
Rule 144 opens the public market after a wait. Rule 144A opens an institutional market right away
As of November 2026 · 17 CFR 230.144, 230.144A; SEC Release 33-9415 (2013). US rules.
In short, Rule 144 trades time for a wide market. Rule 144A trades a narrow market for speed.
How Rule 144 Works: Waiting, Then Selling to the Public
Shares you get from a company in a private deal are restricted securities. So are shares from a startup’s stock plan under Rule 701 and shares bought under Regulation D. The law treats any resale as needing registration unless an exemption applies. Rule 144 gives you a checklist that shows the exemption fits (17 CFR 230.144).
- Holding periodSix months if the company has reported to the SEC for at least 90 days. One year if it does not report. The clock starts when you buy and fully pay for the shares.
- Public informationFor a reporting company, it must have filed all its required reports for the past 12 months.
- Extra limits for insidersAn affiliate, someone who controls the company, can sell up to 1% of the shares outstanding, or the average weekly volume if higher, every three months.
- NoticeAn affiliate selling more than 5,000 shares or $50,000 in three months files a Form 144 with the SEC.
Once the conditions are met, the buyer gets ordinary shares that trade freely. That is the point of Rule 144. It moves shares from a private holder into the public market.
How Rule 144A Works: Selling Only to Large Institutions
Rule 144A lets anyone other than the issuer resell securities to a qualified institutional buyer (QIB). A QIB is an institution that owns and invests at least $100 million in securities of companies it is not tied to. A dealer needs $10 million. A bank also needs an audited net worth of $25 million (17 CFR 230.144A). See QIB for the full test.
The rule has no holding period. Instead it sets four conditions. The buyer must be a QIB. The seller must tell the buyer it relies on Rule 144A. The securities cannot be of the same class as shares listed on a US exchange. And if the issuer does not report to the SEC, buyers can ask it for basic financial information.
The SEC adopted Rule 144A on April 23, 1990. In a typical “Rule 144A offering,” a company sells new bonds or shares to banks called initial purchasers. The banks then resell them to QIBs. In 2012, operating companies raised $636 billion this way, against $1.2 trillion in registered deals (SEC, 2013).
One detail links the two rules. A security bought under Rule 144A is still restricted. To sell it to the public later, the holder has to meet Rule 144 or find another exemption.
Which Is Better for Investors or Employees?
Neither rule is better in general. Each one serves a different seller. Your status decides which one you can use.
- Employees with equityRule 144 is your route. After an IPO, a non-affiliate can resell Rule 701 shares 90 days later without the holding period. The lock-up usually runs longer, so it sets the real date.
- Individual investorsRule 144 again. Shares you bought in a private round become sellable after six months or a year. You cannot buy Rule 144A securities unless you invest through an institution that qualifies.
- InstitutionsRule 144A gives them a market for private bonds and shares with no waiting time. They can also sell under Rule 144 when they want to reach public buyers.
Tax Treatment Compared
Neither rule changes how a sale is taxed. Both are securities rules about who can buy and when. In the US, a gain on shares held more than one year is a long-term capital gain. A gain on shares held one year or less is short-term (26 U.S.C. 1222).
The two clocks are separate. The Rule 144 holding period decides when you may sell. The tax holding period decides how the gain is taxed. For an employee, the tax clock often starts when an option is exercised or a grant vests. Get advice on your own case.
Rule 144 vs Rule 144A Pros and Cons: A Verdict on Each
Rule 144
- For
- Reaches every buyer on the public market. Shares become freely tradable. The checklist is clear.
- Against
- You wait six months or a year. Insiders face volume caps and filings. A private company offers no public market to sell into.
Verdict: Rule 144 is the standard exit for people who hold restricted shares in a company that is public or about to list. Its cost is time. Its reward is access to every buyer.
Rule 144A
- For
- No holding period. Large deals can close quickly. Issuers avoid a full registration.
- Against
- Only QIBs can buy. Securities stay restricted. Disclosure is lighter than in a public offering.
Verdict: Rule 144A suits institutions and the banks that serve them. It turns private securities into a tradable product among large buyers. For an individual it is mostly background.
Rule 144 decides when you can sell to the public. Rule 144A decides who can buy without any wait. Most individuals will only ever use Rule 144.
Rule 144 vs 144A: What Each Means for a Shareholder
If you own shares in a private company, a sale today usually goes through the company’s own transfer process. That can be a tender offer or a secondary transaction to another qualified buyer. Rule 144 becomes the main gate once the company lists.
If you invest through an SPV, the vehicle holds the shares for you. Axevil sets up a separate Delaware SPV for each deal, managed by Axevil Capital, LLC. When the company lists, the vehicle’s own sale still has to clear the same securities rules and any lock-up.
Common Mistakes
- Reading 144A as a faster version of 144It is a different market. Only institutions with $100M invested can buy.
- Starting the clock at the grant dateThe Rule 144 clock starts when you buy and fully pay. For options, that is usually the exercise date.
- Forgetting the lock-upRule 144 can allow a sale while a contract with the IPO banks still forbids it.
- Assuming 144A securities are free to tradeThey stay restricted. A public resale needs Rule 144 or another exemption.
- Mixing the sale clock with the tax clockOne sets when you may sell. The other sets how the gain is taxed.

What People Ask About Rule 144 and Rule 144A
Both are SEC rules for reselling securities that were never registered. Rule 144 lets you sell to the public after a holding period. Rule 144A lets you sell at once, but only to institutions with at least $100M invested.
No. Only qualified institutional buyers can buy under Rule 144A. An individual can get exposure through a fund that qualifies, on that fund’s own terms.
No. A QIB can resell to another QIB at any time. The securities stay restricted, so a sale to the public still needs Rule 144 or another exemption.
No. The securities cannot be of the same class as securities listed on a US exchange when they were issued. That keeps Rule 144A apart from the public market.
It depends. Only affiliates file it, and only when they sell more than 5,000 shares or $50,000 in three months. Most employees who are not officers or directors do not file.

This page explains how a market works. It is not investment advice, not a recommendation of any security, strategy or company, and not an offer to sell or a solicitation to buy anything. Private companies may never list or be acquired, positions in them can be illiquid for years, and the entire amount invested can be lost. Figures are accurate as of the dates shown and change. Requirements for investor status, and the tax treatment of a private holding, differ by jurisdiction — the jurisdiction is named wherever this page discusses either.
