The fastest way to buy S&P 500 exposure on Robinhood
On Robinhood, you can buy S&P 500 exposure in two ways: purchase an exchange-traded fund (ETF) that tracks the index, or buy individual stocks that make up the index. The easiest route for most people is to buy an ETF like VOO, SPY, or IVV — each one holds all 500 companies in the S&P 500, so a single purchase gives you diversified exposure. You search for the ticker symbol in the Robinhood app, enter the number of shares you want, and confirm the purchase. The transaction settles in one business day, and you own the shares when ready.
Robinhood charges no commission on stock or ETF trades, so there are no hidden fees eating into your purchase. The only cost is the price difference between what you pay and what you sell for — the same spread you would face at any broker. If you want to own the actual 500 companies rather than a fund that holds them, you can buy individual stocks one at a time, but that requires 500 separate purchases and leaves you exposed to the performance of whichever companies you happen to pick.
Key Takeaways
- VOO, SPY, and IVV are the three most common S&P 500 ETFs on Robinhood, and each one holds all 500 companies in a single fund.
- To buy an ETF, open the Robinhood app, search the ticker symbol, choose how many shares you want, and confirm the purchase.
- Robinhood charges zero commission on ETF purchases, so you pay only the market price with no added fees.
- Your purchase settles the next business day, but you can sell anytime during market hours if you change your mind.
Finding and selecting an S&P 500 ETF on Robinhood
The three ETFs that track the S&P 500 most closely are VOO (Vanguard S&P 500 ETF), SPY (SPDR S&P 500 ETF Trust), and IVV (iShares Core S&P 500 ETF). All three hold the same 500 companies and move almost identically in price. The main difference is the expense ratio — the annual fee charged by the fund manager — which ranges from about 0.03% to 0.04% per year. At that scale, the difference is negligible for most investors. Pick whichever one feels familiar or has the lowest price per share if you are buying a small number of shares.
To find an ETF on Robinhood, tap the search icon at the bottom of the app and type the ticker symbol (VOO, SPY, or IVV). The fund will appear with its current price, a chart of its performance, and basic information about what it holds. You do not need to read the full prospectus — the app shows you the fund name, the number of holdings, and the expense ratio. That is enough to decide.
How to place your first S&P 500 purchase
Once you have found the ETF you want, tap on it to open the fund page. At the bottom of the screen, you will see a green "Buy" button. Tap it, and a window will open asking how many shares you want to purchase. Enter the number — you can buy fractional shares on Robinhood, so you can spend any dollar amount, not just whole-share increments. For example, if VOO costs $450 per share and you have $100 to invest, Robinhood will sell you 0.22 shares.
After you enter the number of shares, the app shows you the total cost and asks you to confirm. Review the price one more time — market prices move constantly during trading hours, so the price shown when you searched may have changed slightly. Tap "Confirm" to place the order. Your purchase will execute when ready if the market is open, or at the market open the next trading day if you buy after hours or on a weekend.
Understanding settlement and when you own your shares
When you buy an ETF on Robinhood, the order executes right away during market hours, but the shares do not officially settle until the next business day. During that settlement period, you own the shares and can see them in your account, but you cannot sell them until settlement is complete. In practice, this means if you buy on a Monday, you can sell on Tuesday. If you buy on a Friday after market close, settlement happens Monday, and you can sell Tuesday.
Robinhood does not require you to hold shares for any minimum time, so you can sell the day after you buy if you want. However, if you sell within 30 days of buying, Robinhood may flag your account as a pattern day trader if you do this repeatedly. That rule applies only if you have less than $25,000 in your account and make more than three day trades in five business days. Most long-term investors never hit that limit.
Dividend payments and reinvestment options
S&P 500 ETFs pay dividends quarterly because the 500 companies inside them pay dividends to shareholders. When VOO, SPY, or IVV receives those dividends, the fund passes them to you. On Robinhood, dividends land in your cash account automatically. You can then use that cash to buy more shares, or leave it sitting there.
Robinhood does not offer automatic dividend reinvestment (sometimes called DRIP) the way some brokers do. That means if you want to reinvest your dividends, you have to manually buy more shares each time a dividend arrives. For most people, this is not a major inconvenience — dividends arrive four times a year, and buying more shares takes 30 seconds. If you prefer automatic reinvestment, you would need to use a different broker like Vanguard or Fidelity.
Comparing S&P 500 ETFs side by side
| ETF | Ticker | Expense Ratio | Approximate Price Per Share |
|---|---|---|---|
| Vanguard S&P 500 ETF | VOO | 0.03% | $450–$500 |
| SPDR S&P 500 ETF Trust | SPY | 0.09% | $450–$500 |
| iShares Core S&P 500 ETF | IVV | 0.03% | $450–$500 |
All three ETFs track the same index and hold the same 500 companies, so the performance difference is minimal. VOO and IVV have identical expense ratios and are the cheapest options. SPY has a slightly higher expense ratio but is the oldest and most widely traded, which means it has the tightest bid-ask spread — the difference between what buyers will pay and what sellers want. For most Robinhood users, the choice between them does not matter much.
What happens after you buy
Once your shares settle, you own a piece of all 500 companies in the S&P 500. Your account will show the number of shares you own, the current price per share, and the total value of your position. As the market moves, that value will go up and down. You can check your holdings anytime in the Robinhood app under the "Investing" tab.
You do not have to do anything else. The ETF manager handles rebalancing — replacing companies that drop out of the index with new ones — automatically. You straightforward hold the shares and watch them grow. If you want to add more money later, you can buy additional shares anytime the market is open. If you want to sell, you can do that anytime too, though selling within a year of buying may trigger capital gains tax.
Frequently Asked Questions
Can I buy fractional shares of S&P 500 ETFs on Robinhood?
Yes. Robinhood lets you buy any dollar amount of an ETF, not just whole shares. If you have $50 to invest and VOO costs $475 per share, you can buy 0.11 shares. This makes it possible to start investing with small amounts of money.
Do I pay taxes on S&P 500 ETF dividends?
Yes. Dividends are taxable income in the year you receive them, whether you reinvest them or not. If you hold the ETF in a regular taxable account on Robinhood, you will owe taxes on dividends. If you hold it in a Robinhood IRA, dividends are tax-deferred or tax-free depending on the account type.
What is the difference between VOO and SPY?
Both track the S&P 500 and hold the same 500 companies. VOO has a lower expense ratio (0.03% versus 0.09%), making it cheaper over time. SPY is older and more heavily traded, which can mean a slightly tighter bid-ask spread. For most investors, VOO is the better choice.
Can I set up automatic monthly investments in an S&P 500 ETF on Robinhood?
Robinhood does not offer automatic recurring investments. You have to manually buy shares each time you want to invest. If automatic investing is important to you, consider using Vanguard, Fidelity, or another broker that offers that feature.
What happens if I sell my S&P 500 ETF shares within a year?
You will owe capital gains tax on any profit. If you bought at $400 per share and sold at $450, you owe tax on the $50 gain. The tax rate depends on your income and how long you held the shares. Holding for more than a year qualifies for lower long-term capital gains rates.
