What is Palantir?

Palantir is an American technology company, listed on the New York Stock Exchange (NYSE) in the US.

The company floated on the NYSE in September 2020 through a direct listing, meaning it didn’t issue new shares to the public. Instead, it allowed existing shareholders to sell more shares.

When it made its debut on the NYSE it was valued at around $20bn. At the time of writing, Palantir’s market capitalisation (the combined value of all Palantir shares) is $48 billion. 

Historically, Palantir was well-known for its big data analytics and its association with US military and federal agency contracts for its software.

More recently its AI division, known as Artificial Intelligence Platform (AIP), has been making noise as a fast-growing part of the business. It sells its AIP to companies rather than governments and government agencies as with the rest of its business.

This is one of the factors behind the interest in how to buy Palantir shares – the opportunity to invest in an AI stock with growth potential.

Buy Palantir shares in an investment account

You can have as many GIAs as you like, and there are no contribution or withdrawal limits or penalties.

But, you may have to pay income tax, dividend tax or capital gains tax on any gains or income received through a GIA. There are a number of allowances before you’d have to pay tax, but it will come down to your individual circumstances.

Sometimes a GIA is referred to as a dealing account, usually by the more traditional stockbrokers. 

If you’d prefer a traditional stockbroker with modern features and customer support over the phone, then we recommend Interactive Investor.

It has over 40,000 shares and investments to choose from, fees which get cheaper the more you invest and one free trade per month. Its customer service is top-rated, too.

An Individual Savings Account (ISA) is a government approved way of saving and investing without paying certain taxes. 

Through a Stocks and Shares ISA, you can invest in shares, bonds and funds without paying income tax, dividend tax and capital gains tax on your investments.

Whether you’re going to buy Palantir shares or not, you should consider opening a Stocks and Shares ISA as a great, tax-efficient way of building an investment portfolio. You can contribute up to £20,000 a year into a Stocks and Shares ISA. 

We recommend Interactive Investor as our number one Stocks and Shares ISA provider.

Buy Palantir shares in a Lifetime ISA

Lifetime ISAs (sometimes referred to as LISAs) are tax-free savings and investment accounts designed to be put towards your first home, or for retirement. 

You have to be an adult aged 40 or under to open a Lifetime ISA and can contribute up to £4,000 a year, which also counts towards your overall ISA annual allowance of £20,000. 

The great benefit of a LISA is that the government gives you a 25% bonus on all your contributions. 

That can really add up over time, so you should strongly consider opening a Lifetime ISA if you’re eligible. But, there are strict penalties for withdrawing money for any other reason than to buy a first home or for retirement.

Hargreaves Lansdown

Not all investment platforms offer a Lifetime ISA but Hargreaves Lansdown does and it’s one of the lowest cost out there.

There’s a huge range of investments, great customer support and no transfer or exit fees.

Buy Palantir stock through fractional shares

You don’t have to own a whole share in a company when investing these days. You can instead buy a fractional share, which is a proportion of a single share.

Many of the best investment apps in the UK allow you to do this. It’s particularly useful for buying shares in companies with high share prices, which can put them out of reach for new investors.

For example, you can buy 10% or 50% of a share instead of one whole share. This lowers the funds required to get exposure to high-priced shares.

Our preferred platform for buying fractional shares is eToro, and you can buy fractional Palantir shares on their platform. 


eToro is our top-rated investment app, it’s easy to use, has lots of innovative features and allows you to trade commission-free.

Once opened, anyone is able to contribute, such as grandparents, and there’s an annual limit of £9,000. All gains and income generation within a Junior ISA is free from income tax, dividend tax and capital gains tax. 

To buy Palantir shares in a Junior ISA, you’ll need to first open a Junior ISA account for your child. Our top-rated Stocks and Shares Junior ISA is with Hargreaves Lansdown.

How to buy Palantir shares in the UK

We’ve covered all of the main ways to buy Palantir stock in the UK, but as a non-US person, you must complete a form known as W8-BEN

A W8-BEN form is required by the Internal Revenue Service (IRS, the US’s tax collector) for non-US persons who wish to deal in US-listed securities. The key purpose is tax.

The US applies a withholding tax of 30% on non-US persons for dividends and interest income received on US assets. By completing a W8-BEN form, this tax reduces to 15%. Regulated brokers and investment platforms in the UK all require you to complete this form before buying US shares.

All of the investment platforms and brokers in this guide will require you to complete a W8-BEN form before you can buy Palantir shares, unless you do so through a SIPP. Buying US shares within a SIPP is free from US withholding tax and does not usually require a W8-BEN form.

Here’s the prompt you’ll see when buying US stocks and ETFs with eToro:

Buying US stocks and ETFs with eToro requires a W8-BEN form

eToro makes it easy to complete the W8-BEN form through its app and its online platform.

Should you buy Palantir stock?

If you’re reading about how to buy Palantir shares, you’re probably already thinking ‘should I buy Palantir shares?’.

We cannot help you with that one, as we don’t give investment advice. It’s down to you to do your own research on Palantir stock and make your own investment decision. 

The investment platforms we’ve covered above all have tools and resources available to help you with your research and analysis. We suggest you make use of them – especially the tons of features that eToro provides.

All of the investment platforms in this guide are regulated by the Financial Conduct Authority (FCA) and are part of the Financial Services Compensation Scheme (FSCS), protecting up to £85,000 of your money in the unlikely event that the platform goes out of business.

Note: to buy Palantir stock and to buy Palantir shares means essentially the same thing. Buying stock, or owning stock, tends to be more widely used in the USA than in the UK. 

Start investing

That covers how to buy Palantir stock in the UK. Let’s summarise.
