Buy SpaceX & Nvidia Stock: Revolut vs Cash App vs M1 Finance

If you opened your phone this morning to headlines about SpaceX going public at a $1.75 trillion valuation — one of the largest IPOs in history — you weren't alone. SpaceX's stock (ticker: SPCX) priced at $135 a share, raised roughly $75 billion, and was reportedly oversubscribed by more than 400%. In a move that's almost unheard of for a deal this size, SpaceX set aside 30% of the offering for retail investors — typically retail gets just 5–10% of a mega-IPO.

And SpaceX isn't the only mega-cap making headlines this month. Anthropic (maker of Claude, valued at $965 billion after a fresh $65 billion funding round) and OpenAI (valued at up to $852 billion) have both confidentially filed paperwork for stock market debuts — meaning three of the most closely watched private companies on the planet could all go public within months of each other. Add in Nvidia, the chipmaker powering the AI boom behind all three, sitting at a Strong Buy consensus with analyst price targets near $300, and it's easy to see why "how to buy stocks" is suddenly one of the most-searched phrases of 2026.

The good news: you probably don't need to open a new brokerage account to get in on any of this. Apps like Revolut, Cash App, and M1 Finance — the same category of apps people use for international money transfers and multi-currency accounts — now let you buy fractional shares of US and UK stocks in a few taps. Here's how each one stacks up, and exactly how to place your first order.

Before we get into the apps, here's a quick rundown of what's driving the current wave of interest — and why it matters if you're thinking about investing.

Neither Anthropic nor OpenAI shares are available to buy yet — "confidentially filed" means the paperwork is private, with no ticker or listing date set. But the filings are a strong signal that 2026 could see a wave of AI mega-IPOs follow SpaceX's lead, and Nvidia remains the easiest way to get exposure to the AI infrastructure behind all three companies today.

All three apps let you buy fractional shares of US-listed stocks with no trading commission — but they differ a lot on availability, fees, and what else the app does for you. Here's the full breakdown:

Revolut: The All-Rounder — and Our Pick

Revolut is the only one of the three that works equally well whether you're in the US, the UK, or the EU — which matters this week, because European and UK retail investors are accessing SpaceX's offering specifically through fintech platforms like Revolut, alongside brokers such as Hargreaves Lansdown and eToro. On top of stock access, Revolut is also a full multi-currency account: the same balance you use to hold GBP, EUR, or USD for international transfers can be used to buy stocks instantly, with no separate funding step. Paid plans (Plus, Premium, Metal, Ultra) unlock more commission-free trades per month, but the free Standard plan is enough for most casual investors getting started.

Cash App Investing: Simple and US-Only

Cash App keeps things minimal: no commissions, no account minimums, and fractional shares from $1. It's tightly integrated with Cash App's peer-to-peer payments, so if you already use it to split bills or send money to friends, your investing balance is one tap away. The catch is it's US-only, and if you ever want to move your shares to another broker, Cash App charges a $75 outbound transfer fee.

M1 Finance: Best for Hands-Off, Automated Investing

M1's standout feature is "Pies" — you build a portfolio (say, 40% Nvidia, 30% an S&P 500 ETF, 30% cash) and every deposit is automatically split across it in those proportions, with no manual buying required. It's the closest thing to a robo-advisor that still lets you pick individual stocks like SpaceX or Nvidia yourself. The $3/month fee is waived once your balance passes $10,000, and like Cash App, it's US-only.

Here's exactly how easy it is to buy your first share on Revolut — most people can go from download to owning a slice of Nvidia or SpaceX in under five minutes:

1. Download Revolut and verify your identity. Sign up with your phone number and email, then verify with a passport or driving licence — approval is usually instant.
2. Fund your account. Transfer money from your bank, or use a balance you already hold in your Revolut multi-currency account. If you're converting from another currency first, Revolut's free monthly FX allowance covers most casual investors.
3. Open the "Stocks" tab. It sits alongside your currency accounts and crypto — no separate app, login, or paperwork needed.
4. Search for the stock. Type the ticker — SPCX for SpaceX or NVDA for Nvidia — to open the stock page, where you'll see the live price chart and company details.
5. Choose how much to invest. Enter a dollar or pound amount (from $1/£1) rather than a number of shares — Revolut buys the equivalent fraction of a share automatically.
6. Review and confirm. Check the order summary, confirm with Face ID or a PIN, and you're done. Your new position appears in your portfolio immediately.

That's the entire process — no separate brokerage login and no minimum balance. You can set up a Recurring Buy afterwards if you'd rather invest a fixed amount automatically every week or month, which is a popular way to build a position in a volatile stock like SPCX without trying to time the market.

If you're in the US and prefer Cash App or M1 Finance, the process is similarly fast:

Cash App Investing

1. Open Cash App and tap the Investing tab.
2. Search for the stock by ticker (e.g., NVDA or SPCX).
3. Tap Buy, enter a dollar amount (from $1), and confirm with your PIN or Touch ID.

Cash App also offers automatic round-ups: every card purchase rounds up to the nearest dollar, and the spare change is invested into a stock or ETF of your choice.

M1 Finance

1. Create an account and fund it via bank transfer (typically 1–3 business days for ACH).
2. Build or edit a "Pie" — add individual stocks like Nvidia (and SpaceX, once tradable on the platform) alongside ETFs, and set target percentages.
3. Deposit funds, and M1 automatically buys across your Pie to match your targets. One-off trades outside your Pie are also available.

Both platforms are solid choices if you're US-based and don't need multi-currency features — but neither helps if you're sending or receiving money internationally, which is where Revolut's combined approach has an edge.

If you're choosing one app to ride this wave of IPOs and AI stocks, Revolut comes out on top — and not by a small margin. Here's why:

• It works wherever you are. US, UK, and EU investors can all use the same app — useful given that European access to SpaceX's offering is happening specifically through platforms like Revolut.
• It's the account you might already have. If you use Revolut to send money abroad or hold a multi-currency balance, your stock purchases come straight out of that balance — no extra funding step, no separate FX conversion.
• Fractional shares from $1 mean you can build a position in SpaceX, Nvidia, or a future Anthropic/OpenAI listing gradually, without needing hundreds of dollars upfront.
• One free trade a month, even on the Standard plan — and zero ongoing account fees if you stay within that.

🏆 Bottom line: Cash App and M1 Finance are both excellent, low-cost choices if you're US-based and only need stock investing. But if you want stocks, multi-currency holding, and international transfers in one place — especially with more mega-IPOs likely on the way — Revolut is the easiest single app to set up today.

SpaceX's 19% first-day pop and Nvidia's Strong Buy ratings make for exciting headlines, but newly listed and high-momentum stocks carry real risks that are easy to overlook in the excitement:

• IPO volatility. Newly listed stocks can swing sharply in either direction in their first days and weeks of trading, as the market works out a "fair" price with limited trading history to go on.
• Lock-up periods. Early investors and employees are often restricted from selling shares for a period after an IPO. When those lock-ups expire, a wave of selling can pressure the share price.
• Concentration risk. Putting a large share of your portfolio into one or two hyped stocks — even ones you believe in — increases your exposure to a single company's bad news.
• Currency risk. If you're a UK or EU investor buying US-listed stocks like SPCX or NVDA, movements in the GBP/USD or EUR/USD exchange rate affect your returns independently of the share price itself. Our exchange rate markup guide explains how this works in practice.

None of this means you shouldn't invest — it just means starting small, diversifying, and only investing money you can afford to have tied up (or lose) is generally a better approach than putting everything into the stock of the moment.
