Anthropic IPO explained

Key takeaways

  • Fidelity customers with at least $25,000 in certain assets at Fidelity may be eligible to participate.
  • Selling shares within 15 days of the IPO (known as flipping) may restrict your ability to participate in future IPOs through Fidelity.
  • Fidelity may receive only a small percentage of an overall offering, which means not all customers may receive an allocation, especially when demand for shares is significant. Submitting an Indication of Interest (IOI) for an offering does not entitle you to receive an allocation of shares. Customers may receive fewer shares than they requested or, in some cases, no shares at all.

What is the Anthropic initial public offering (IPO)?

The Anthropic initial public offering (IPO) would be the first time Anthropic sells its shares to the public. This means the company would move from private ownership to being publicly traded on the stock market.

Some shares will be allocated to eligible investors as part of the IPO. Once the stock begins market trading, the investors who didn’t participate in the IPO or didn’t receive an allocation can buy shares on a public exchange at its initial offering price. An IPO gives investors a chance to own part of Anthropic, but there may be limited shares available and added risk when the stock first starts trading.

What is an initial public offering (IPO)?

An initial public offering (IPO) is when a private company first sells shares of stock to the public. An IPO means that a company's ownership is transitioning from private ownership to public ownership. For that reason, the IPO process is sometimes referred to as "going public."

Who is eligible to participate in the Anthropic initial public offering (IPO)?

Fidelity customers with a minimum of $25,000 in certain assets may be eligible to participate in initial public offerings (IPOs) at Fidelity, including Anthropic's IPO.

If I am allocated shares of Anthropic during the initial public offering (IPO), when can I sell them?

As with any investment, you are free to sell the securities obtained during an initial public offering (IPO) whenever you determine it is appropriate for you. However, if you are allocated shares of Anthropic and you sell within the first 15 calendar days from the start of trading in the secondary market, it will affect your ability to participate in future new issue equity public offerings through Fidelity for a defined period of time. The first day clients can sell without being labeled a "flipper" is the 16th calendar day after the IPO trades. The defined period is as follows:

  • First Flip – Blocked for 6 months
  • Second Flip – Blocked for 1 year
  • Third Flip – Permanently banned by your SSN

How will shares of the Anthropic initial public offering (IPO) be allocated?

Fidelity’s allocation methodology evaluates customers based on their relationship with Fidelity as defined by their Social Security number (SSN) or taxpayer identification number (TIN). Each customer who participates in an initial public offering (IPO) offering is evaluated and ranked based on the assets and revenue they have in accounts under their SSN. Assets include all retail assets under the individual’s SSN/TIN and exclude assets or trades maintained on behalf of any divisions of Fidelity Investments Institutional Services Company, such as 401(k) or 403(b) plan assets.

Revenue is comprised of the brokerage commissions, margin interest, and mutual fund revenue generated in retail accounts of the individual’s SSN. The allocation methodology is done as fairly and equitably as possible. The size of a customer’s indication of interest (IOI) is not considered during allocation other than the fact that we will not allocate more than the customer requested. Therefore, you should only enter an indication of interest for the amount of shares you are interested in purchasing, as entering a larger number will not help you receive additional shares, and there is always the possibility that you could be allocated everything you ask for.

Note: If you are entering indications of interest in multiple accounts, Fidelity will look at the account with the smallest IOI qty first. If all IOI quantities are the same, Fidelity will begin with the account whose IOI was entered first. If shares are allocated to you, you must have enough cash available in the account to pay for the purchase by settlement, which is usually the business day following the trade day "T+1." Keep in mind that some account types, such as IRAs, may have contribution limits or other restrictions that could impact your ability to add funds.

How many shares can I attempt to purchase in the Anthropic initial public offering (IPO)?

For the Anthropic initial public offering (IPO), the minimum indication of interest (IOI) quantity is 25 shares, with increments of 25 share thereafter, up to a maximum of 1,000,000 shares. The system will automatically enforce the minimum, increment, and maximum quantities and provide an error message if you do not meet them.

How much will Anthropic stock cost per share during the initial public offering (IPO)?

Any customer who participates in the Anthropic initial public offering (IPO) and is allocated shares in the offering will purchase shares at the public offering price, also known as the IPO price. When the offering is launched, there will be a price range on the preliminary prospectus. The price range provides an indication of what the offering price may be, but the offer price could be higher or lower than the expected price range.

How can I attempt to buy Anthropic stock during the initial public offering (IPO)?

Eligible customers must follow Fidelity's initial public offering (IPO) process for the offering, which can be found at How to participate in the Anthropic IPO.

Am I guaranteed an allocation of shares of Anthropic if I follow all the steps in the initial public offering (IPO) process?

Like many initial public offerings (IPOs), demand may be high. Fidelity may receive only a small percentage of an overall offering, which means not all customers may receive an allocation, especially when demand for shares is significant. Submitting an indication of interest (IOI) for an offering does not entitle you to receive an allocation of shares. Customers may receive fewer shares than they requested or, in some cases, no shares at all.

Making an informed decision about investing in Anthropic IPO shares

Before investing, be sure to do your own due diligence. This task can be challenging because of the lack of readily available public information on a company that is issuing stock for the first time. However, you should always refer to the issuing company’s preliminary prospectus, also known as a "red herring." This document, provided by the issuer and lead underwriter, will include information on the company's management team, target market, competitive landscape, the company's financials, who is selling shares in the offering, who currently owns shares, expected price range, potential risks, and the number of shares to be issued.
