Anthropic Stock: How to Buy, IPO Date and Pre-IPO via XTB

Anthropic stock does not trade on an exchange yet, but the IPO is close: the company behind the AI assistant Claude filed its prospectus with the US Securities and Exchange Commission on 26 October 2026 and plans to list on Nasdaq under the ticker ANT. Investors in Europe and the UK have three routes: today the pre-IPO CFD at XTB, a subscription at the offer price, and from the first trading day the actual share. This page shows when each route opens, what it costs and which risks come with it. We will update it as soon as the price range is set.

Key facts at a glance

• Ticker: ANT, Class A common stock on the Nasdaq Global Select Market, applied for in the prospectus of 2 November 2026.
• Date: Anthropic has not named a date yet, XTB expects mid to late November 2026.
• Price: The prospectus of 2 November does not yet include a price range or share count.
• Before the IPO: pre-IPO CFD ANTH.24H7 at XTB, a contract for difference with no share ownership. 78% of retail investor accounts lose money when trading CFDs with this provider.
• From the first trading day: the actual share at XTB, 0% commission up to the equivalent of €100,000 monthly turnover, 0.5% currency conversion.
• Financials: $33.2 billion in revenue and a $1.26 billion operating loss in the first nine months of 2026.

Can you already buy Anthropic stock?

You can buy actual Anthropic stock once it is listed on Nasdaq. Until then it does not trade on the open market. If you want a position on the price now, a pre-IPO CFD is the route, and if you want the share in your account, you get that account ready.

The prospectus of 2 November says the same: Anthropic is applying to list its Class A common stock under the ticker ANT and states that there has been no public market for the stock before this offering. Any offer promising you actual Anthropic shares in advance therefore deserves a close look.

XTB covers two of these three routes: the pre-IPO CFD is already running, and according to XTB the actual share will also be tradable there after the IPO. Which XTB products are open to you depends on your country of residence, so check this in the app. XTB’s Anthropic information (ad) summarises the date and how to prepare. Other providers are listed in our broker comparison.

Update 6 November: how to be ready for the Anthropic IPO

Update 7 November: The timeline is now uncertain. After the sell-off in AI and tech stocks on 5 November, Anthropic could struggle to start its roadshow in the week of 9 November as planned, according to Reuters. Several investors told the Wall Street Journal that the valuation will likely need to come down from the targeted $1.5 trillion, and one suggested around $1 trillion. There is still no price range, and Anthropic has not announced a delay. For your preparation nothing changes: you need an account that is ready either way, whether trading starts in November or later.

The IPO is getting closer. According to Bloomberg, the roadshow, where Anthropic presents the shares to large investors, could start in the week of 9 November at the earliest. Reports point to a first trading day before Thanksgiving on 26 November, and Fox Business mentioned 19 or 20 November. As of 5 November, Anthropic had not published a price range, as FinanceFeeds sums up.

New is Anthropic’s own list of retail brokers. In the UK, the retail offer runs through AJ Bell, eToro, Hargreaves Lansdown, Interactive Brokers, Interactive Investor and Revolut, coordinated by RetailBook. In the European Economic Area it covers Denmark, Finland, France, Germany, Ireland, the Netherlands, Norway, Spain and Sweden, plus Switzerland, with BNP Paribas, Crédit Agricole CIB, Deutsche Bank, eToro, flatexDEGIRO, Interactive Brokers, Nordnet, Revolut, Saxo Bank, Trade Republic and UBS. Australia, Canada and Japan have their own lists. Anthropic has not authorised any other platform for these retail offers.

Checklist before the first trading day

1. Open an account: whether you subscribe or buy on Nasdaq, you need an account that is fully set up before the date.
2. Verify your identity: the ID check often takes minutes, but follow-up questions can take days. If you only start on the first trading day, you may be too late.
3. Fund the account: a bank transfer can take a working day or more. With cash in the account, you can trade as soon as the first price is set.
4. Choose your route: subscribe through a listed broker, buy from the first trading day, or use the pre-IPO CFD before that. For day one, a limit order sets the highest price you are willing to pay.

At XTB, buying from the first trading day and the pre-IPO CFD run through the same account. If you open an XTB account (ad) now, it is ready on the day. Which products are open to you depends on your country of residence.

XTB’s client information explains two details of the ANTH.24H7 CFD: the price assumes 1 billion shares and therefore reflects the expected valuation in billions of dollars. On IPO day, open positions are settled at the last price and automatically reopened, with price and size converted to the actual share count, and pending orders are cancelled. CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. 78% of retail investor accounts lose money when trading CFDs with this provider (XTB Limited UK, 79% at XTB in the EU).

Other ways before the IPO: outside the EU and the UK, Bitget (ad) lists an ANTHROPIC/USDT pre-market perpetual contract with up to 20x leverage. In Europe, OKX (ad) offers pre-IPO futures on Anthropic with up to 10x leverage, and the 21Shares Anthropic Synthetic ETP (ticker CLAU, 1% annual fee) has traded on the Vienna MTF since 8 October. None of these products makes you a shareholder, and perpetual contracts with high leverage can wipe out your stake quickly.

Anthropic IPO: date, ticker and price range

The Anthropic IPO does not have an official date yet. In its Anthropic information, XTB expects a Nasdaq listing in mid to late November, and CoinDesk reported 19 or 20 November as the expected pricing date. These are expectations, not statements from the prospectus.

The prospectus does not name a valuation yet. CoinDesk cited the Financial Times with an expectation of $1.5 trillion to $1.75 trillion. Goldman Sachs and Morgan Stanley lead the list of banks in the prospectus. How an IPO of this size works for retail investors is shown in our guide to SpaceX stock.

Subscribing to the Anthropic IPO: what investors in Europe and the UK should know

Anthropic plans its own offers for retail investors outside the United States. According to the US prospectus, the offering includes public offerings in Australia, Canada, certain member states of the European Economic Area, Japan, Switzerland and the United Kingdom. In the European Economic Area, shares will be offered through a separate prospectus that is expected to be approved by the German financial regulator BaFin. The US prospectus does not say which member states are included.

A report by EU Personal Finance of 3 November lists nine countries: Denmark, Finland, France, Germany, Ireland, the Netherlands, Norway, Spain and Sweden. It names BNP Paribas, Crédit Agricole CIB, Deutsche Bank, eToro, flatexDEGIRO, Interactive Brokers, Nordnet, Revolut, Saxo Bank, Trade Republic and UBS as firms expected to take part. The list covers the countries as a group, so not every firm will be active in every country. XTB is not on it, so at XTB the first trading day is your starting point. Anthropic’s own IPO page for Europe showed no details on 3 November, and the minimum amount and offer period are still to come. A subscription does not guarantee an allocation, and the offer price can differ significantly from the first market price.

Anthropic pre-IPO: how the ANTH.24H7 CFD at XTB works

XTB’s pre-IPO CFD is a contract for difference based on a tokenised Anthropic share. It lets you take a position on the price before the IPO without becoming a shareholder. According to XTB it trades under the ticker ANTH.24H7 from Saturday 04:00 to Friday 23:00, subject to the applicable trading schedule.

The price of such a contract reflects what market participants estimate for a price that does not exist yet. How far these pre-market prices can drift apart is shown in our analysis of the ANTH perp on Hyperliquid: four markets, three different prices.

XTB risk warning: CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. 78% of retail investor accounts lose money when trading CFDs with this provider. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.

How to buy Anthropic stock at XTB: four steps to the first trading day

To buy on the first trading day you need an account that is fully set up, because identity verification has to be finished by then. These four steps get you ready.

1. Open an account: Register for an account at XTB (ad), which according to XTB takes a few minutes. Our assessment of the provider is in our XTB review.
2. Deposit funds: Add money to your account so that you are ready when trading starts.
3. Find Anthropic in the search: When trading starts, XTB says you will find the share through the search in the app. Make sure you pick the share and not the ANTH.24H7 CFD.
4. Set a limit: Prices often swing widely on the first trading day. With a limit order you set your maximum price yourself.

The main cost is the currency, because ANT trades in dollars. For one purchase and one sale of £1,000 each, the calculation at XTB looks like this:

Above the equivalent of €100,000 monthly turnover, XTB charges 0.2% commission, with a minimum of £10.

Anthropic financials: revenue and losses in the prospectus

Anthropic’s revenue grew roughly thirteenfold within a year, while the company still reports an operating loss. For the first nine months of 2026 the prospectus shows $33.242 billion, up from $2.545 billion in the same period a year earlier. The third quarter alone brought in $17.0 billion.

The headline figure of $104 billion in net loss is misleading: $94.324 billion of it comes from changes in the fair value of convertible notes, derivatives and SAFEs, which grow as the valuation rises. That is an accounting entry, not cash going out. The commitments carry more weight: Anthropic reports about $895.4 billion in committed spending, almost all of it for compute and infrastructure, including about $447.5 billion through the end of 2030.

A simple calculation puts this in context: annualised, the third quarter comes to $68 billion in revenue. At the $1.5 trillion to $1.75 trillion expected by the Financial Times, the valuation would be 22 to 26 times that figure. Further growth has to justify this premium, and the prospectus itself states that past growth rates say nothing about future results.

Anthropic funding: who invested before the IPO

Anthropic was founded in 2021 in San Francisco by a team around the siblings Dario Amodei, the chief executive officer, and Daniela Amodei, president and chair of the board, together with five other co-founders. The company is organised as a public benefit corporation under Delaware law and puts AI safety at the centre of its mission, so it has to balance shareholder returns against that public purpose. Its AI assistant Claude launched publicly in the first quarter of 2023.

Before the initial public offering, Anthropic raised money from venture capital firms, institutional investors and its two big cloud partners. The prospectus filed with the Securities and Exchange Commission lists the last three funding rounds:

The price per preferred share more than quadrupled in about nine months. In Series H, Google invested $10 billion and Amazon $5 billion, according to the prospectus, and Spark Capital took part in all three rounds. Series F was led by ICONIQ, with Fidelity Management & Research Company and Lightspeed Venture Partners as co-leads, according to Anthropic. The round also drew institutional investors such as D1 Capital Partners, General Atlantic, General Catalyst, Insight Partners, the Ontario Teachers’ Pension Plan, the Qatar Investment Authority, T. Rowe Price Associates and WCM Investment Management. Earlier, Lightspeed had led a $3.5 billion Series E in March 2025 at a $61.5 billion post-money valuation. For the IPO, reports put Anthropic’s valuation at $1.5 trillion to $2 trillion.

Anthropic in the artificial intelligence market

In the prospectus, Anthropic names Google and OpenAI as its main competitors. Claude is available on all three major cloud platforms, Amazon Web Services, Google Cloud and Microsoft Azure, and runs on chips from Amazon (Trainium), Google (TPUs), NVIDIA and AMD. That makes Amazon and Google partners, investors and in part rivals at the same time. Non-voting Class N shares are held mainly by strategic partners, according to the prospectus, and convert into Class A shares when sold to a third party.

Can you invest in Anthropic shares before the initial public offering?

Not with actual Anthropic shares on a public stock exchange. Until the listing, Anthropic stock is private company stock, like the shares of other private companies. In the US, accredited investors can sometimes buy pre-IPO shares from early investors or employees on private market platforms such as Forge Global, EquityZen or Nasdaq Private Market, but private company stock usually comes with transfer restrictions, and prices there are indications rather than an Anthropic stock price. Anthropic warns on its help pages about unauthorised share sales and investment fraud. For everyone else, the routes to invest in Anthropic before the IPO are derivatives and synthetic products such as the pre-IPO CFD at XTB or the 21Shares ETP. Neither makes you one of the Anthropic shareholders.

Is the Anthropic IPO worth buying at the IPO price?

That depends on the Anthropic IPO price, which is only set the evening before the first trading day, and on how the stock price moves after that. In favour: revenue of $33.2 billion in the first nine months of 2026, up from $2.5 billion a year earlier. Against: an operating loss of $1.26 billion over the same period, around $895.4 billion in contractual commitments, mostly for computing power, a valuation in the trillions, and lock-ups of 180 and in some cases 365 days, after which early investors can sell Anthropic shares. Big IPOs often swing sharply on the first day, so a limit order and a position size you can afford to lose matter more than the exact date.

Anthropic stock: voting rights, dividends and lock-ups

A Class A share carries one vote, but shareholders do not decide the board majority with it. That majority is elected by the Long-Term Benefit Trust through a separate share class, Class T. Anthropic does not plan to pay a dividend for the foreseeable future and intends to put earnings back into the business.

Existing shareholders are subject to lock-ups of 180 and in some cases 365 days, which the prospectus combines with staggered earlier releases. Each release can increase the supply of shares on the market.

Claude stock: does it exist?

There is no separate Claude stock. Claude is the product, and the company going public is the one behind it, Anthropic PBC. If you are searching for Claude stock, you mean ANT.

If you would rather cover AI more broadly, XTB also names Alphabet, AMD and the L&G Artificial Intelligence UCITS ETF. Alphabet deserves a second look: according to the prospectus, Google is both a competitor of Anthropic and a supplier of compute.

Anthropic stock and tax: the UK and other countries

How gains on Anthropic stock are taxed depends on where you live, so check the rules of your country before you buy. In the UK, Capital Gains Tax applies to gains above the tax-free allowance of £3,000. The rates from 6 April 2026 are 18% within the basic Income Tax band and 24% above it.

You do not pay tax on income or capital gains from investments held in an ISA, so it is worth asking your provider whether ANT can be held in one. CFDs have their own tax treatment. If you want to bring several accounts and crypto together, you will find suitable programs in our comparison of crypto tax software. For your individual case, speak to a tax adviser.
