The answer depends on which type of account you want to open and which market you want to trade. The general rule is 18 for an independent brokerage account in the United States. But the full picture is more nuanced: minors can access stock markets through custodial accounts at any age, one major broker offers a teen-specific account from age 13, and some markets have higher effective minimums due to regulatory requirements. This article covers every scenario.
How old do you have to be to trade stocks? You must be 18 to open an independent brokerage account in the US. Under 18, stocks can be purchased through a custodial account at any age, or through the Fidelity Youth Account from age 13. The adult controls the account until the minor reaches 18 in most US states.
A MarketWatch report noted that kids as young as 13 can now trade stocks without parental approval through dedicated teen investing platforms. Fidelity launched the Youth Account for 13 to 17 year olds in 2021. A FINRA Investor Education Foundation survey found that teenagers who had invested or begun learning about investing showed significantly higher financial literacy scores than those who had not. Starting early builds habits and knowledge that compound over time in ways that financial returns alone do not capture.

| Account type | Minimum age | Who controls it | Notes |
|---|---|---|---|
| Standard brokerage account | 18 | Account holder (independent) | Most common account type. Full access to stocks, ETFs, options (with approval), and more. |
| Custodial account (UGMA/UTMA) | Any age | Parent/guardian until age of majority | Adult opens account as custodian. Assets belong to the child but adult manages until 18 (or 21 in some states). |
| Fidelity Youth Account | 13-17 | Teen (with parent linked account) | Teen can place trades independently. Parent receives notifications and can monitor. No account minimum. |
| Roth IRA (custodial) | Any age with earned income | Parent/guardian until age of majority | Requires the minor to have earned income (wages from a job). Contribution limit: lesser of $7,000 or earned income in 2026. |
| Margin account | 18 | Account holder (independent) | Required for short selling and pattern day trading. Not available to minors. |
The age of majority varies by US state. In most states it is 18. In Alabama and Nebraska it is 19. In Mississippi it is 21. For UTMA accounts specifically, some states allow the custodian to set a later transfer age, up to 25 in some jurisdictions. The age of majority determines when the assets transfer to the child's independent control, not when the account can be opened. The account can be opened at any age with a custodian.
One common question from beginner investors: how old do you have to be to trade stocks on Cash App? Cash App Investing requires users to be 18 or older with a valid government-issued ID, the same requirement as any other regulated US broker. Cash App Investing offers commission-free stock and ETF trading through a standard brokerage account. It does not offer a custodial account option for minors. Under 18, Cash App Investing is not available: the custodial account routes at Fidelity, Schwab, or through the Fidelity Youth Account are the appropriate alternatives.
Can you trade stocks under 18
Yes, under 18s can invest in stocks through two main routes. The first is a custodial account (UGMA or UTMA), where a parent or guardian opens an account on the child's behalf, manages the investments until the child reaches the age of majority, and then transfers control. There is no minimum age and no minimum deposit at most brokers. The second is the Fidelity Youth Account, which allows teenagers aged 13 to 17 to independently place trades in stocks and ETFs with a linked parent account providing oversight. The key distinction: in a custodial account the adult makes the investment decisions; in the Fidelity Youth Account the teenager places trades independently.
The UGMA (Uniform Gifts to Minors Act) and UTMA (Uniform Transfers to Minors Act) accounts are the two standard custodial account types in the US. UGMA accounts hold financial assets only (stocks, bonds, cash). UTMA accounts can hold a broader range of assets including real estate and intellectual property in some states. For stock investing purposes, the practical difference is minimal. Both are available at Fidelity, Schwab, and Vanguard with no account minimum.
One important tax consideration: custodial accounts are subject to the kiddie tax rules. Investment income above a certain threshold (for 2026, the first $1,300 of unearned income is tax-free, the next $1,300 is taxed at the child's rate, and amounts above $2,600 are taxed at the parent's rate for dependents under 19 or full-time students under 24). For most teenage investors with small accounts, the kiddie tax is not a practical concern, but parents should be aware of it as the account grows.
Age by age: what each age can actually do
The most valuable thing a teenager can do with the years before independent account access is build investing knowledge and habits. Reading about markets, practicing with paper trading or simulators, tracking real stocks on a watchlist without money, and using the Fidelity Youth Account for real small-dollar experience all compound in value. The investors who perform best in their first year of independent investing are almost always those who spent the most time preparing before that account opened. For the practical learning sequence, trading for beginners step by step covers the full framework.
How old do you have to be to day trade stocks specifically
Day trading has a higher effective age requirement than standard stock investing, because of the margin account requirement. Pattern day trading (making four or more day trades within five business days) requires a margin account with minimum equity under pre-2026 rules. The old $25,000 pattern day trader requirement was eliminated by FINRA Regulatory Notice 26-10, effective June 4, 2026, but the margin account requirement itself remains, and margin accounts require the account holder to be 18.
Custodial accounts are cash accounts, not margin accounts. A minor with a custodial account or Fidelity Youth Account can buy and sell stocks, but they cannot access margin, short selling, or the pattern day trading designation. In practice, a teenager can buy a stock and sell it the same day in a cash account, but the settlement rules mean the proceeds are not immediately available for another same-day trade. This effectively limits active day trading for under-18s even in the accounts available to them.
The practical answer for a teenager interested in day trading: wait until 18 for a margin account. In the meantime, use the available years to study markets, practice on paper trading platforms, develop a strategy, and build the knowledge base that makes the transition to live day trading far more effective than starting blind at 18. For the reality of what day trading demands from a full-time or part-time perspective, what does a day trader do all day covers the complete routine.
How old do you have to be to trade forex, options, futures, and crypto
| Market | Min age (US) | Account type required | Under-18 options |
|---|---|---|---|
| Stocks (standard) | 18 | Standard brokerage | Custodial account (UGMA/UTMA) or Fidelity Youth Account from age 13 |
| ETFs and index funds | 18 | Standard brokerage | Same as stocks. ETFs available in custodial and Fidelity Youth accounts. |
| Options | 18 | Options-approved brokerage account | Not available in custodial accounts or Fidelity Youth Account. Minimum 18. |
| Futures (E-mini, micro) | 18 | Futures-enabled brokerage account | Not available to minors. Minimum 18, and many futures brokers set their own minimum at 21. |
| Forex | 18 | CFTC-regulated forex account | Not available to minors. US-regulated forex brokers (OANDA, tastyfx) require 18 with valid ID. |
| Cryptocurrency | 18 | Regulated crypto exchange account | Most major exchanges (Coinbase, Kraken) require 18. No regulated custodial crypto equivalent to UGMA/UTMA. Crypto ETFs accessible through custodial stock accounts. |
Options, futures, and forex each have 18 as the hard minimum because they require account types that are not available to minors. Many futures brokers additionally set their own internal minimum at 21, independently of the regulatory floor. Crypto exchanges are regulated differently from securities brokers, but the major US-regulated platforms also enforce the 18 minimum with ID verification. A teenager who wants crypto exposure before 18 has the most practical route through a crypto ETF (such as a Bitcoin ETF or Ethereum ETF) held in a custodial stock account, which provides price exposure without requiring a direct crypto exchange account.
Can you trade stocks under 18 in the UK? The UK framework differs from the US. The minimum age for an independent stocks and shares ISA or general investment account in the UK is 18. Under 18, the primary route is a Junior ISA (JISA), which is the UK equivalent of the US custodial account. A parent or guardian opens a Junior ISA on behalf of a child under 18. The annual contribution limit for a Junior ISA is GBP 9,000 per tax year (2026-27). The child cannot access the money until they turn 18, at which point the Junior ISA automatically converts to an adult ISA in their name. At 18, UK residents can open a standard stocks and shares ISA (annual limit GBP 20,000) or a general investment account with any FCA-regulated broker. Hargreaves Lansdown, Freetrade, and Trading 212 are among the most accessible platforms for first-time UK investors. At 16 and 17, UK residents can open an adult cash ISA but not a stocks and shares ISA. The Junior ISA remains the stock market access route for all under-18s in the UK.
How to buy stocks for a child as a gift
Buying stocks for a child as a gift is a meaningful and practical alternative to toys or cash gifts, especially for birthdays, holidays, and milestones. The standard mechanism is a custodial account. Here is how it works.
The gift of stocks differs from the gift of cash in one important way: it introduces the child to the concept of ownership in businesses, compounding returns, and market fluctuation. A child who receives Apple shares and watches the price move has a tangible connection to how markets work that no amount of financial education fully replicates. The educational value of owning real shares, even a fraction, is often worth more than the financial value of the holding itself.
How to invest as a teenager: the practical starting point
For a teenager who wants to start building investing knowledge and real investment experience before age 18, the practical sequence is straightforward.
Step one: open the Fidelity Youth Account at 13 (or ask a parent to open a custodial account at any age). The Fidelity Youth Account is the most accessible independent investing option for teenagers. No minimum deposit. No fees. Fractional shares from $1. A parent links their own Fidelity account and receives notifications. The teenager places their own trades and builds real investing experience with real money, even if the amounts are small.
Step two: start with index ETFs before individual stocks. A broad market ETF tracking the S&P 500 (such as VOO, IVV, or SPY) is the most appropriate starting investment for a teenager for two reasons. First, it provides immediate diversification across 500 companies, which limits the risk of a single company's problems affecting the entire investment. Second, it teaches the most important investing concept: that long-term consistent investing in broad markets historically produces positive returns, and that time in the market matters more than timing the market.
Step three: invest regularly rather than in one lump sum. Contributing a fixed amount monthly, whatever the market is doing, removes the temptation to time entries and builds the habit of consistent investing. A teenager who invests $25 per month from age 15 to 18 and continues through young adulthood will have a significantly different financial position in their 30s and 40s than one who starts at 25 with the same annual contribution. Compound growth rewards time above all else.
Step four: use the years before 18 to learn, not just invest. The investing knowledge built between 13 and 18, through reading, paper trading, tracking watchlists, and managing a small real account, compounds into a meaningful advantage when the full range of markets opens at 18. A teenager who reaches 18 with three to five years of genuine market engagement starts their independent investing from a position that takes most adults years to reach. For the honest assessment of what trading and investing demand in terms of skill and time, is trading hard to learn covers the full picture. For understanding whether trading as a side income alongside education is viable, trading as a side income covers the framework.
Is there a maximum age to start trading stocks
There is no maximum age to start trading stocks. Any adult aged 18 or over can open a standard brokerage account and begin investing at any age. The only age-related consideration for older investors is retirement account rules: traditional IRAs require minimum distributions starting at age 73. Standard taxable brokerage accounts have no age-based restrictions at either end. A person starting to invest at 60, 70, or 80 can open an account and trade stocks without any age-related barrier. The investment strategy appropriate at 70 differs from the one appropriate at 25 due to time horizon and risk tolerance, but the ability to open an account and invest has no upper limit.
The distinction between trading (shorter-term, active) and investing (longer-term, passive) becomes more relevant with age due to time horizon differences, but it does not affect access. A 65-year-old who wants to actively trade stocks faces no regulatory barrier to doing so. The practical considerations around risk management, position sizing, and capital preservation become more important as time horizon shortens, but those are strategy considerations, not eligibility ones. For anyone at any age starting from the beginning, how to start trading covers the practical first steps.
How old do you have to be to trade stocks: the summary
The minimum age for an independent brokerage account is 18 in the United States. Under 18, the two primary routes are a custodial account (UGMA or UTMA) opened by a parent or guardian at any age, and the Fidelity Youth Account, which allows teenagers aged 13 to 17 to trade stocks and ETFs independently with parental oversight. Options, futures, forex, and most crypto exchanges require 18 as a hard minimum with no custodial equivalent.
The years before 18 are not wasted time for a teenager interested in investing. They are an opportunity to build the knowledge, habits, and experience that make independent investing at 18 far more effective than starting cold. The investors who perform best in their first years of independent access are consistently those who prepared most seriously during the years before it. There is no maximum age. The starting point is now, wherever "now" happens to be on the age spectrum.
