Anthropic IPO Shares: 6 Brokers, Zero Guarantees
Anthropic set aside up to 20% of its IPO for regular investors through six brokers. Here is how a request works, what each broker asks, and why most buyers will still pay the market price.

Quick Read
There are two ways to buy Anthropic stock. Before the IPO is priced on Nov 18, eligible customers of six brokers named in the filing (Charles Schwab, Fidelity, Robinhood, SoFi, E*Trade from Morgan Stanley and the adviser platform TradePMR) can request shares at the offer price, with no guarantee of getting any. From Nov 19, when ANT starts trading on Nasdaq, anyone with a brokerage account can buy at the market price. Anthropic confirmed both dates on Nov 12.
The dates are no longer reported. They are set. Anthropic (ANT) confirmed on Nov 12 that it will price its IPO on Wednesday, Nov 18, and start trading on Nasdaq on Thursday, Nov 19.
That leaves a few days for the question we get most: can a regular investor buy at the IPO price? The filing says up to 20% of the offering can go to retail investors. That is up to about 165 million shares, worth roughly $11.6 billion to $12.9 billion at the $70 to $78 range. It is a large slice by IPO standards. It is also shared by every eligible customer who asks, at six brokers.

The six brokers in the Anthropic IPO
Broker | How you ask | What it asks of you |

SoFi | Request through its IPO center | A funded Self-Directed Invest account; no minimum balance |
Fidelity | Indication of interest through its IPO calendar | At least $25,000 in certain Fidelity assets; requests of 25 to 1,000,000 shares, in 25-share steps; offer period expected to close Nov 17, 4 PM ET |
Charles Schwab | Request after an eligibility questionnaire | An asset minimum set by Schwab |
E*Trade from Morgan Stanley | Conditional offer to buy through its New Issue Center | A completed Investor Profile and prospectus acknowledgment; only requests you can pay for count |
TradePMR | Through a financial adviser on the platform | Adviser-led accounts |

Four of the six belong to listed companies: Robinhood (HOOD), Charles Schwab (SCHW), SoFi (SOFI) and Morgan Stanley (MS), which owns E*Trade. Fidelity is private. TradePMR is part of Robinhood. On the other side of the deal, Morgan Stanley and Goldman Sachs (GS) lead the group of banks selling the shares.
Requesting is not buying: how the IPO line works
An IPO request is a conditional order. You say how many shares you would like at the final price, up to a limit. You are not buying anything yet.
The order runs in five steps:
Check eligibility at a participating broker. Each one has its own account and asset rules.
Submit a request before the cutoff your broker sets, which falls before pricing. Brokers call it a conditional offer to buy or an indication of interest. Most require the cash to be in the account.
The price is set after the market closes on Nov 18. Some brokers ask you to reconfirm once the final price is known.
Allocations are made, if any. Anthropic and its banks decide how much goes to each broker; each broker then decides how to split its share among customers.
ANT trades on Nasdaq on Nov 19, and any shares you received are yours to hold or sell.

The allocation step is where most requests shrink. Fidelity says customers may get fewer shares than they asked for, or none, and that it weighs a customer's overall relationship with the firm. SoFi says it looks at several factors, including the size of the request.

How much of the Anthropic IPO goes to retail?
Up to 20% of the 825 million shares on offer, or about 165 million shares. The rest goes to institutions through the banks running the deal. Separately, seven companies that supply Anthropic's computing power are buying $26 billion of non-voting stock at the IPO price, outside this offering.
That is a big retail slice. But "up to" is the key phrase. The final split depends on demand, and it is shared across six brokers and every eligible customer who asks.

The rules that come after
Getting shares comes with conditions most people skim.
Holding periods. Fidelity says selling within 15 days of the IPO may limit your access to future IPOs there. Other brokers set their own rules on selling soon after an IPO.
Cash on hold. Brokers generally need the money for your full request in the account until allocations are done. If you get fewer shares, the rest frees up.
Partial fills. Getting 10 shares on a 100-share request is a normal outcome in a popular deal.

Buying ANT on Nov 19: the first trade is not at 9:30
Most people who own ANT will buy it on Nasdaq, at the market price.
A new listing does not open with the bell. Nasdaq runs an opening auction for it, called the IPO Cross, and that auction only starts once the lead bank says the stock is ready. Orders can sit in the queue for a long time before the first trade prints.
The last mega listing shows how it plays out. SpaceX (SPCX) priced at $135 on Jun 11. Its first trade came just before noon the next day, at $150. It reached $176.52 that afternoon and closed at $160.95. By late July it was about 50% below its post-listing peak.
A market order fills at whatever price the auction sets. A limit order sets the most you will pay. Every participating broker explains both on its IPO pages.
What is not Anthropic stock
Before Nov 19, anything quoted as "Anthropic" or "ANT" outside a broker's IPO request page is not a Class A share on Nasdaq. Tokenized products and pre-IPO trackers may follow the name. They do not make you a registered shareholder.

The Velvet Rope
An IPO allocation works like a velvet rope. The rope is real, the line is long, and the people inside do not decide who comes next.
Up to 165 million shares sounds like a lot until you count the line. Most investors will meet ANT the way they meet every other stock: on the exchange, at a price the market sets, after the auction is done. The useful work happens before that, in knowing what the company is worth to you and what you will do if the first print is far from $70 to $78.
