You can own a piece of Apple, Amazon, or Starbucks for $1

Three apps that make investing as simple as online shopping

You use Amazon. You drink Starbucks. You carry an iPhone. You already know which companies are good because you buy from them every day.

What most people don’t realize is that you can own a piece of those companies for as little as $1. Not a mutual fund. Not a complicated options contract. An actual share — or a fraction of one — of the companies you already know and trust.

It’s called fractional investing, and it changed who gets to participate in the stock market. You don’t need thousands of dollars. You don’t need a financial advisor. You don’t need to know what a P/E ratio is. Three apps have made it possible to start investing with pocket change, with zero commissions and no account minimums.

We compared the three most popular ones to help you decide which is worth opening.

What fractional shares are and why they matter

A single share of Amazon costs over $180. Apple is around $170. For most of the stock market’s history, you had to buy a whole share — which meant you needed hundreds or thousands of dollars just to own one company.

Fractional shares changed that. Instead of buying a full share, you buy a dollar amount. Put in $5, and you own $5 worth of Amazon. Put in $1, and you own $1 worth of Apple. You get the same proportional gains (or losses) as someone who owns 100 shares. The only difference is you started smaller.

This is what made investing accessible to everyone, not just people with large portfolios. And it’s why platforms like Public have made it their core feature.

New brokerage accounts opened by retail investors surged 50% between 2020 and 2024, driven largely by commission-free platforms and fractional share investing. The average age of new account holders has dropped, but the fastest-growing segment is adults over 50 opening their first self-directed brokerage account.

Is my money safe in these apps?

This is the most common question, and it’s the right one to ask. Here’s what you should know:

All three platforms are registered with the SEC and regulated by FINRA — the same agencies that oversee traditional brokerages like Fidelity and Charles Schwab.
Your investments are protected by SIPC (Securities Investor Protection Corporation) for up to $500,000, including up to $250,000 in cash. This covers you if the brokerage fails, not if the stock market goes down.
All three companies are publicly traded on major stock exchanges. Their financials are audited and publicly available.
You don’t need to understand the stock market to start. Fractional shares let you invest in companies you already know. SoFi’s automated option builds a diversified portfolio for you based on your goals.
You can withdraw your money at any time. There are no lock-up periods or early withdrawal penalties on standard brokerage accounts (IRAs have their own rules).
Investing always involves risk — stock prices go up and down. But owning a small piece of a company you believe in is fundamentally different from gambling. You’re buying a share of a real business.

What happens after you open an account

Opening a brokerage account takes about 5 minutes on any of these platforms. You’ll enter basic personal information (name, address, SSN for tax reporting — this is required by law for all brokerage accounts) and connect a bank account for funding.

Once approved (usually instant or within a day), you can deposit money and buy your first fractional share. On Public, that means browsing for a company you recognize — Apple, Amazon, Starbucks, Nike, Disney — and buying as little as $1 worth.

From there, you can invest as much or as little as you want, on your own schedule. There’s no monthly fee, no required deposit amount, and no pressure to trade frequently. Most people start small, see how it feels, and go from there.

Own a piece of the companies you already use

Public lets you start investing with as little as $1. No commissions, no minimums, no expertise required.

Investing involves risk, including the possible loss of principal. Past performance does not guarantee future results. Fractional shares involve additional risks, including less liquidity during market volatility. All three platforms are registered with the SEC, regulated by FINRA, and are SIPC members. SIPC protects against the loss of cash and securities held by a customer at a financially-troubled SIPC-member brokerage firm. SIPC does not protect against market losses.
