Key Takeaways
- Filed, not priced: Anthropic's S-1 sets no price range or IPO date yet.
- Ticker ANT on Nasdaq: the company has applied to list its Class A shares.
- Options two days after the IPO: big IPOs can list options on the second business day after the debut.
- A $3 billion bar: the fast track depends on market cap at the offering.
- Listing is not automatic: exchanges still decide when to add an options class.
As of Monday, October 26, 2026, Anthropic has made its IPO filing public, and the first question we are hearing from options traders is a practical one: how soon after the Anthropic IPO could ANT options trade? The short answer is that exchange rules allow options on a large IPO to list as early as the second business day after it debuts, but nothing about the timing is fixed until the offering is priced.
Here is what the filing says, what the listing rules allow, and what we would watch between now and the first trade.
What Happened With the Anthropic IPO Filing
Anthropic filed a public S-1. In its registration statement on Form S-1, filed with the SEC on October 26, Anthropic, PBC says it has applied to list its Class A common stock on the Nasdaq Global Select Market under the symbol "ANT." The filing states that there has been no public market for the Class A shares before this offering.
The key numbers are still blank. The S-1 leaves the estimated price range as "between $ and $," and Anthropic's own announcement says the number of shares and the price range have not yet been determined and that the registration statement has not yet become effective. Goldman Sachs and Morgan Stanley head the underwriter list on the prospectus cover.
The filing also describes an unusual structure. Anthropic is a Delaware public benefit corporation with several share classes, and the S-1 says it will be a "controlled company" under Nasdaq governance rules. None of that changes how options get listed, but it is part of what the market will be pricing.
Why It Matters Now
Options on a big IPO can arrive fast. Under the standard test in Cboe's Rule 4.3, a covered stock's closing price must be at least $3.00 for the three business days before the exchange sends its listing certificate to the Options Clearing Corporation. Cboe's filing gave a worked example: an IPO on a Monday could not see options trade until Friday.
The 2023 change carved out large deals. If a newly public stock has a market capitalization of at least $3 billion based on its IPO offering price, the three-day price test is waived, and options "may be listed and traded starting on or after the second business day following the initial public offering day." In Cboe's framing, that day count excludes the IPO day itself, so the same Monday debut could see options as early as Wednesday.
Cboe's BZX options exchange filed a matching change days later, and the Federal Register notice followed in September 2023. Cboe's filing also notes that NYSE American adopted the same standard first, under an SEC approval order in July 2023, and said it expected the change to be harmonized across options exchanges.
The rule sets the earliest day options may list. It does not oblige any exchange to list them that day.
What We're Watching
The checkpoints between the filing and a first options trade:
- An amended S-1 with a price range. The $3 billion bar is measured at the offering, so the range and share count would tell us whether the fast track could apply on paper.
- The roadshow window. Because Anthropic submitted its draft confidentially first, SEC staff procedures call for the public filing at least 15 days before any roadshow, which puts the earliest start around November 10. Pricing usually comes at the end of the roadshow.
- Pricing and the first trading day. The calendar math starts from the IPO day, so a debut date pins down the earliest possible options date.
- Exchange listing notices. Options exchanges and the OCC announce new option classes; that notice, not the rule, is the real start date.
- The final prospectus terms. Lock-up provisions and the share count on each class shape how much stock can trade in the early weeks.
- The first options chain itself. Early implied volatility will tell us how much movement the market is pricing in a stock with no trading history.
What This Could Mean for Options Traders
If the offering values Anthropic above the $3 billion bar, which looks likely given that the S-1 shows single private rounds raising about $13 billion and $23.5 billion, the fast-track rule could put listed ANT options in front of traders within days of the debut. That is a meaningful change from the pre-2023 rules, when the earliest listing for a Monday IPO was Friday, as it still is for smaller deals.
Early chains on new listings tend to be expensive and volatile, because the stock is still in price discovery and there is no trading history to anchor expectations. Our explainer on why IPO options can be so volatile covers that behavior in depth, and our guide to calculating the expected move shows how to translate a high implied volatility into a dollar range before deciding whether a premium looks rich or cheap.
Further out, lock-up expirations tend to become their own volatility events once insiders can sell, a dynamic we cover in our piece on lock-up expiration plays. Your risk tolerance, account size, and broader portfolio context determine whether any of this fits, or doesn't.
Until the price range is in the prospectus, every ANT options timeline is a scenario, not a schedule.
FAQ
These answers cover what options traders are asking now that Anthropic's registration statement is public.
When Is the Anthropic IPO?
Anthropic has not set a date, and its S-1 still leaves the price range blank.
Because it submitted its draft confidentially, SEC staff procedures call for the public S-1 to be on file at least 15 days before any roadshow, so a roadshow could start around November 10 at the earliest, with pricing usually at its end.
When Will Anthropic Options Start Trading?
There is no date yet, because the IPO itself has not been priced or scheduled.
Under exchange rules adopted in 2023, options on an IPO valued at $3 billion or more at the offering may list starting the second business day after the IPO day, so a Monday debut could see options as early as Wednesday.
What Is Anthropic's Stock Ticker?
Anthropic has applied to list its Class A common stock on the Nasdaq Global Select Market under the symbol ANT, according to its S-1. The listing is not effective until the registration statement is declared effective and the offering prices.
Why Do Some IPOs Wait Longer for Options?
Under Cboe's standard test, options may list only if a covered stock has closed at $3 or more for the three business days before the listing certificate goes to the Options Clearing Corporation, so a Monday IPO would not see options until Friday.
Only IPOs valued at $3 billion or more at the offering qualify for the faster path.
Can I Trade Options on Anthropic Before the IPO?
No listed options can exist before a stock has a public market, and the S-1 states that no public market for the Class A shares exists yet. Listed options can only follow once the shares trade and an exchange adds an options class.
