Three main routes to invest in AI: buy individual company stocks, buy funds that hold multiple AI companies, or invest in AI infrastructure and startups through specialized vehicles

If you want to own a piece of artificial intelligence companies, you have three paths. You can buy stock in individual companies that make or use AI — like Nvidia, Microsoft, or Tesla. You can buy a fund (mutual fund or exchange-traded fund) that holds a basket of AI-related stocks, so you own pieces of many companies at once. Or you can invest in private AI startups and infrastructure through venture capital funds or special investment accounts, though this route requires more money upfront and locks your cash away longer.

Each route has different costs, different risks, and different time horizons. Individual stocks let you pick specific companies but require you to research them yourself. Funds spread your risk across many companies but charge fees and may hold companies you don't want to own. Private investments can offer higher returns but are harder to sell and often require $25,000 or more to start.

Key Takeaways

  • Individual AI company stocks (Nvidia, Microsoft, Broadcom, Palantir) trade on regular stock exchanges and can be bought through any brokerage account with as little as one share.
  • AI-focused funds and ETFs hold dozens of AI companies in a single purchase, spreading risk but charging annual fees that range from 0.3% to 1.5% of your investment.
  • Private AI venture funds require minimum investments of $25,000 to $100,000 or more and lock your money away for 7 to 10 years, but may offer higher returns if the startups succeed.
  • AI stocks are volatile — prices swing sharply based on earnings reports, new product announcements, and shifts in regulation — so money you need within five years should not go into individual stocks.
  • You need a brokerage account (through a bank, online broker, or investment app) to buy stocks or funds; you cannot buy them directly from the companies.

Buying individual AI company stocks

The most direct route is to open a brokerage account and buy stock in companies that make AI chips, software, or services. Nvidia manufactures the graphics processors (GPUs) that train large language models and power data centers — it supplies chips to nearly every major AI company. Microsoft has invested billions in OpenAI and integrates AI into its cloud services and Office products. Broadcom makes networking chips for data centers. Palantir builds AI software for government and enterprise customers. Tesla uses AI in autonomous driving systems.

To buy these stocks, you open an account at a brokerage — Fidelity, Charles Schwab, E-Trade, Robinhood, or your bank's investment arm all offer this. You fund the account with cash, then place an order to buy shares. You can buy as few as one share of most stocks. Commissions are usually zero; you pay only the price of the stock itself plus any bid-ask spread (the tiny difference between what buyers and sellers are willing to pay). Once you own the shares, you own them until you sell.

Individual stocks require you to monitor company earnings, product announcements, and competitive threats. If a company's AI strategy falters or a competitor leaps ahead, the stock price can drop 20% or 30% in days. You also have to decide when to sell — holding too long can mean watching gains evaporate, and selling too early means missing further gains. This is why individual stocks work best for money you can afford to lose and time you can spend researching.

AI-focused mutual funds and exchange-traded funds

A fund is a pool of money managed by a professional or tracked to an index, holding dozens or hundreds of stocks. An exchange-traded fund (ETF) is a type of fund that trades on a stock exchange like a regular stock — you can buy and sell it anytime during market hours. A mutual fund is priced once per day after the market closes.

AI-focused funds hold stocks in companies across the AI supply chain: chip makers, software companies, cloud providers, and companies using AI in their products. Examples include the Ark Innovation ETF (ticker ARKK), which holds AI and technology companies; the Global X Artificial Intelligence ETF (AIQ); and the iShares Robotics and Artificial Intelligence ETF (IRBO). Each fund holds 40 to 100+ different stocks, so if one company stumbles, it is a small part of your total investment.

Funds charge an annual fee called an expense ratio, typically 0.3% to 1.5% of your investment per year. A fund with a 0.5% expense ratio costs you $50 per year on a $10,000 investment. You pay this fee whether the fund gains or loses money. Funds also handle buying and selling for you — the fund manager or algorithm decides which stocks to hold and when to trade them. This removes the need to research individual companies, but it also means you own stocks you may not have chosen yourself.

Funds are less volatile than individual stocks because losses in one company are offset by gains in others. They work well for money you plan to hold for five years or longer and for investors who do not want to pick individual stocks.

Venture capital and private AI investment

If you have significant money and a long time horizon, you can invest in private AI startups through venture capital funds. These are pools of money that invest in early-stage or growth-stage companies not yet traded on public stock exchanges. Startups working on large language models, AI chips, robotics, or AI software often raise money this way.

Venture funds typically require a minimum investment of $25,000 to $100,000 or more. Your money is locked up for 7 to 10 years — you cannot sell your stake or withdraw cash during that time. The fund managers invest your money across multiple startups, betting that a few will become very valuable and offset losses in others. If a startup succeeds and is bought or goes public, you may see returns of 5x to 10x your investment. If it fails, you lose that money.

Private investments are riskier than public stocks because you have less information about the company, cannot sell quickly if you need cash, and depend entirely on the fund manager's skill. They work only for investors with money they will not need for a decade and a high tolerance for losing it. Many people access venture funds through their employer's retirement plan or through a financial advisor who specializes in alternative investments.

How to open a brokerage account and buy your first shares

To buy stocks or funds, you need a brokerage account. Choose a broker based on fees, ease of use, and whether they offer the stocks or funds you want. Most major brokers (Fidelity, Schwab, E-Trade, Vanguard, Robinhood) charge no commission to buy stocks or ETFs and offer thousands of funds.

Open an account online by providing your name, address, Social Security number, and employment information. Link a bank account to fund your brokerage account — this usually takes one to three business days. Once the account is funded, you can place an order. Search for the stock ticker (NVDA for Nvidia, MSFT for Microsoft) or fund name, enter how many shares you want to buy, and confirm the order. The trade executes immediately during market hours (9:30 a.m. to 4 p.m. Eastern time on weekdays) or at the market open the next day if you place an order after hours.

You can set up automatic monthly investments — many brokers let you transfer a fixed amount from your bank account each month and automatically buy a stock or fund. This is called dollar-cost averaging and reduces the risk of buying everything at the peak of a price spike.

Costs, taxes, and account types

When you buy stocks or funds, you pay the price of the shares themselves. Most brokers charge no commission. Some funds charge a sales load (an upfront fee of 1% to 5%), though you can avoid these by buying no-load funds. All funds charge an annual expense ratio.

When you sell a stock or fund for more than you paid, you owe capital gains tax. If you held it for less than one year, it is taxed as short-term capital gains at your regular income tax rate. If you held it for one year or longer, it is taxed as long-term capital gains at a lower rate (0%, 15%, or 20% depending on your income). Dividends paid by stocks or funds are also taxable in the year you receive them.

You can reduce taxes by holding investments in a tax-advantaged account. A traditional or Roth IRA lets you invest up to $7,000 per year (or $8,000 if you are 50 or older) with tax benefits. A 401(k) through your employer may let you invest more. In these accounts, you do not pay capital gains tax when you sell, and dividends are not taxed annually — you pay tax only when you withdraw money in retirement (or never, in a Roth IRA). This is why most investors put their long-term stock and fund investments in an IRA or 401(k) first.

Risk and volatility in AI investing

AI stocks and funds are more volatile than the overall stock market. Nvidia's stock has swung 20% to 30% in a single month based on earnings surprises or competitive news. This volatility creates opportunity — if you buy low and sell high, you can make large gains. But it also means you can lose money quickly if you buy at the wrong time or panic-sell during a downturn.

Volatility is manageable if you have a long time horizon. If you invest money you will not need for 10 years, short-term price swings do not matter — what matters is whether the company or fund is worth more in 10 years than today. But if you need the money in two years, a 30% drop could force you to sell at a loss.

Diversification reduces risk. Owning one AI stock is riskier than owning an AI fund with 50 stocks. Owning an AI fund is riskier than owning a broad market fund with 500 stocks. Most financial advisors suggest putting only 5% to 20% of your portfolio in high-risk, high-growth sectors like AI, with the rest in diversified index funds and bonds.

Frequently Asked Questions

Do I need a lot of money to start investing in AI stocks?

No. You can buy a single share of most stocks for $100 to $500, or buy an AI ETF for the same price. Many brokers let you set up automatic monthly investments of $50 or $100. Start with what you can afford to lose and add to it over time.

What is the difference between an ETF and a mutual fund?

Both hold baskets of stocks, but ETFs trade like stocks (you can buy and sell anytime during market hours) and usually have lower fees. Mutual funds are priced once per day and may have higher expense ratios. For most investors, ETFs are simpler and cheaper.

Should I invest in AI through my 401(k) or IRA?

Yes, if you can. Tax-advantaged accounts let you avoid capital gains tax on AI stocks and funds, which compounds your returns over time. Most 401(k)s and IRAs offer AI-focused funds or let you buy individual AI stocks. Max out your IRA contribution first ($7,000 per year), then use your 401(k) if your employer offers one.

What happens if an AI company I own stock in goes bankrupt?

You lose your investment — the stock becomes worthless. This is why diversification matters. If you own 50 AI stocks through a fund, one bankruptcy is a small loss. If you own one stock, it could wipe out that investment. Never put money into individual stocks that you cannot afford to lose.

Can I invest in AI startups without $100,000?

Some equity crowdfunding platforms (AngelList, SeedInvest) let you invest in private startups with $500 to $5,000, though these are very high-risk and illiquid. For most people, AI-focused ETFs offer better access to AI growth at lower cost and risk.
