Yes, you can buy S&P 500 index funds on Robinhood, but not as a single stock

Robinhood does not let you buy the S&P 500 directly as one ticker. Instead, you buy an exchange-traded fund (ETF) or mutual fund that tracks the S&P 500. The most common choices are SPY, IVV, and VOO — each holds the same 500 large-cap stocks in the same proportions as the index itself. You buy these the same way you would buy any individual stock on Robinhood: search the ticker, enter the number of shares, and confirm the order.

The difference between these three funds is small. SPY has been around longest and trades with the highest volume. VOO has the lowest expense ratio (the annual fee you pay), currently 0.03 percent. IVV sits in the middle on both counts. For most people starting out, any of the three will work the same way — you own a piece of all 500 companies, your money grows or shrinks with the index, and you pay almost nothing in annual fees.

Key Takeaways

  • You cannot buy the S&P 500 as a single investment on Robinhood; you must buy an ETF or mutual fund that tracks it, such as SPY, VOO, or IVV.
  • All three funds hold the same 500 stocks in the same weights, so the choice between them matters less than the choice to buy one at all.
  • You can buy fractional shares on Robinhood, so you do not need $400 or $500 to start — you can invest $1 and own a tiny piece of all 500 companies.
  • Robinhood charges no commission to buy or sell these funds, and the funds themselves charge almost nothing in annual fees.
  • You can set up automatic recurring investments (called "recurring investments" on Robinhood) to buy shares on a schedule you choose.

The three most common S&P 500 ETFs on Robinhood

SPY (SPDR S&P 500 ETF Trust) is the oldest and most heavily traded. It has been around since 1993 and moves enormous volume every day, which means you can buy or sell quickly without moving the price. The expense ratio is 0.09 percent — meaning you pay $9 per year on every $10,000 invested. SPY is run by State Street.

VOO (Vanguard S&P 500 ETF) has the lowest cost at 0.03 percent annually. It holds the exact same 500 stocks as SPY and IVV. Vanguard is known for low-cost investing, and this fund reflects that philosophy. If you plan to hold for decades, the difference between 0.03 and 0.09 percent compounds into real money.

IVV (iShares Core S&P 500 ETF) sits between the two. The expense ratio is 0.03 percent, matching VOO. It is run by BlackRock. The main reason to choose IVV over VOO is if you already own other iShares funds and want to keep everything in one family, but that is a minor consideration for most people.

How to place an order on Robinhood

Open the Robinhood app and tap the search icon at the bottom. Type the ticker (SPY, VOO, or IVV). Tap the fund name when it appears. You will see the current price, a chart, and a green "Buy" button. Tap "Buy," then enter the dollar amount you want to invest or the number of shares. Robinhood will show you how many fractional shares you will own — for example, $50 might buy you 0.15 shares of VOO at current prices. Confirm the order, and it will execute immediately during market hours (9:30 a.m. to 4 p.m. Eastern time on weekdays).

If you place an order after market close or on a weekend, Robinhood will queue it to execute when the market opens the next trading day. You will see the order in your "Investing" tab marked as "Pending" until it fills. Once filled, the shares appear in your portfolio and you own them outright — there is no waiting period or settlement delay on Robinhood.

Fractional shares and minimum investment amounts

Robinhood lets you buy fractional shares, meaning you do not need to own a whole share to start. If VOO costs $450 per share and you have $50, you can buy 0.11 shares. This matters because it removes the barrier of entry — you can invest any amount, even $1, and own a real piece of the S&P 500. Over time, if you add more money, your fractional shares add up to whole shares and beyond.

There is no minimum investment amount on Robinhood. You can buy $1 worth of an S&P 500 fund if you want. The only practical limit is Robinhood's own account minimums — Robinhood has no account minimum for the standard brokerage account, though some features (like margin) require $2,000.

Costs and fees you will actually pay

Robinhood charges zero commission to buy or sell these funds. You will not see a $5 or $10 fee per trade the way you might at some older brokerages. The only ongoing cost is the expense ratio built into the fund itself — 0.03 percent for VOO or IVV, 0.09 percent for SPY. That fee is deducted automatically and you never write a check for it; it simply reduces the fund's value slightly each year.

If you sell at a profit, you may owe capital gains tax, but that is a tax issue, not a Robinhood fee. Robinhood will send you a tax form (1099-B) at the end of the year showing your sales and gains. State and local taxes vary by where you live.

Setting up automatic recurring investments

Robinhood lets you schedule automatic purchases on a weekly, biweekly, or monthly basis. Tap the fund, scroll down, and look for "Recurring Investment" or "Set Up Recurring Investment." Choose your frequency and dollar amount, and Robinhood will buy that amount of the fund on your chosen schedule. This is useful if you want to invest a fixed amount every paycheck without having to remember to log in and place an order each time.

You can pause, change, or cancel a recurring investment at any time. The money comes from your Robinhood cash balance, so make sure you have enough cash on hand when the purchase is scheduled to execute. If you do not, the order will fail and you will see a notification.

Tax implications and holding periods

When you sell an S&P 500 fund at a profit, the gain is taxable. If you held it for more than one year, it is taxed as a long-term capital gain, which usually has a lower tax rate than ordinary income. If you sold within one year, it is a short-term gain taxed at your regular income tax rate. Robinhood does not handle taxes for you — you report the gains on your tax return or work with a tax professional.

There is no tax penalty for holding an S&P 500 fund on Robinhood. You can hold it forever if you want. Dividends paid by the fund (the S&P 500 companies pay dividends, and the fund passes them to you) are also taxable in the year you receive them, whether or not you sell the fund.

Frequently Asked Questions

Can I set up automatic dividend reinvestment on Robinhood?

Robinhood does not offer automatic dividend reinvestment (DRIP) for ETFs. When your S&P 500 fund pays a dividend, the cash lands in your account and you must manually reinvest it if you want to. This is a minor inconvenience but not a deal-breaker — you can set a calendar reminder to reinvest quarterly.

What is the difference between an ETF and a mutual fund tracking the S&P 500?

SPY, VOO, and IVV are all ETFs. Robinhood also offers mutual funds that track the S&P 500, such as VFIAX (Vanguard S&P 500 Index Fund). The main difference is that ETFs trade throughout the day like stocks, while mutual funds trade only once per day at the closing price. For most people, ETFs are simpler on Robinhood because you can buy them instantly.

Can I buy S&P 500 funds in a retirement account on Robinhood?

Yes. Robinhood offers IRAs (both traditional and Roth) and you can buy S&P 500 ETFs inside them. The same three funds — SPY, VOO, IVV — are available. Money in an IRA grows tax-free (Roth) or tax-deferred (traditional), which makes it an especially good place to hold index funds long-term.

What happens if I sell my S&P 500 fund at a loss?

You can deduct capital losses against capital gains and up to $3,000 of ordinary income per year on your tax return. If your loss is larger than that, you can carry it forward to future years. Robinhood will report the loss on your 1099-B, but you handle the deduction yourself on your tax return.

Is it better to buy SPY, VOO, or IVV?

For most people, VOO is the best choice because it has the lowest expense ratio (0.03 percent) and is run by Vanguard, a company known for low costs. SPY is fine if you prefer the oldest, most-traded option. IVV is essentially identical to VOO. The difference between them is so small that your choice to invest at all matters far more than which one you pick.
