How to Invest in Drones

Last updated July 2026

Short answer

You invest in drones by first understanding that the space splits into two very different halves, then buying through a brokerage account. On one side are steadier, established defense and aerospace names that already sell unmanned systems (widely watched examples include AVAV, KTOS, and LHX). On the other side are smaller, far more speculative commercial-drone and eVTOL air-taxi startups (examples include RCAT, ONDS, ACHR, and JOBY), many of which are small, pre-profit, and volatile. There is no large dedicated drone ETF, so a broad aerospace-defense fund is the usual way to get diversified, indirect exposure. Because the pure-plays are so speculative, sizing any position small and keeping the rest of your portfolio diversified is the honest discipline. This page is educational and is not investment advice. Walnut is not an investment adviser and does not tell you what to buy.

Drones are one of those themes where the story is exciting and the stocks are messy. The word covers everything from battle-tested military reconnaissance aircraft to prototype electric air taxis that have not carried a paying passenger yet, and those businesses could not be more different as investments. This guide walks through the drone landscape, the split between steadier defense names and speculative commercial and eVTOL pure-plays, the individual companies people tend to look at, and, most importantly, an honest look at how small and unproven many of these companies are. It closes on position sizing and diversification, because with a theme this speculative, how much you hold matters more than which name you pick. Nothing here is a recommendation, and Walnut is not an investment adviser.

Step 1: Understand the drone landscape

Before you buy anything, it helps to see that “drones” is not one market. The theme spans two very different kinds of business, and a stock behaves very differently depending on which side it sits on.

Defense and military drones. Unmanned aircraft and systems sold mainly to governments and militaries: reconnaissance, surveillance, loitering munitions, and related hardware. This side is dominated by established aerospace and defense companies with real, often recurring revenue and diversified programs.
Commercial drones and eVTOL air taxis. Smaller companies building drones for commercial uses (delivery, inspection, mapping, agriculture) or electric vertical-takeoff-and-landing aircraft meant to become urban air taxis. Many are early-stage, pre-profit, and still working through technology, regulation, and demand.

That split is the single most important thing to internalize. A defense contractor with drone revenue and a pre-revenue eVTOL startup are both “drone stocks,” but they carry completely different risk. You can explore the space through the drones theme and see the individual names side by side in our best drone stocks guide.

Step 2: Open an account

You need a brokerage account to buy any stock or fund. The account wrapper affects your taxes more than which drone name you pick, so choose it deliberately.

A tax-advantaged retirement account such as a Roth IRA or a 401(k) with a match lets holdings grow without yearly tax drag. Most people fund these before a taxable account, though a highly speculative theme is not what these accounts are usually built around.
A standard brokerage account for anything beyond your retirement contributions, or if you want full flexibility to buy and sell individual names.

Any major US broker works, and most now charge no commission on stock and ETF trades, with fractional shares that let you start small, which matters a lot for a speculative theme where keeping the position small is the whole point.

Step 3: Decide between steadier defense names, speculative pure-plays, or a small allocation

This is the central choice, and it flows directly from the split in Step 1. Broadly, there are three ways people approach drone exposure, and they carry very different risk.

Way in	Example tickers	What it is
Defense-drone stocks	AVAV, KTOS, LHX	Established defense and aerospace companies with real drone and unmanned-systems revenue, often alongside other government programs. Generally steadier and more established than the pure-plays, though still tied to defense budgets and contract timing.
Commercial-drone / eVTOL stocks	RCAT, ONDS, ACHR, JOBY	Smaller pure-plays focused on commercial drones or electric air-taxi (eVTOL) aircraft. Many are small, pre-profit, and highly speculative, with revenue that is early or not yet meaningful. Prices can swing hard on news.
Aerospace-defense ETFs	No large dedicated drone ETF	There is no big, established fund that holds only drone companies. Broader aerospace and defense ETFs give indirect, diluted exposure because they hold drone makers alongside jets, missiles, and other defense businesses.

The steadier defense route. Established defense and aerospace companies with drone revenue tend to be larger, profitable, and diversified across many programs, so drones are one line of business rather than the whole company. Widely watched names include AVAV, KTOS, and LHX. They are still exposed to defense budgets and contract timing, but they are generally far more established than the pure-plays. This is not a suggestion to buy any of them.

The speculative pure-play route. Commercial-drone and eVTOL names such as RCAT, ONDS, ACHR, and JOBY offer more direct, concentrated exposure to the drone story, but with much higher risk. Many are small, pre-profit, and volatile, with prices that can swing hard on a single headline. Some may never reach sustained profitability. Owning these is closer to a speculative bet than a core holding.

A small allocation. Some people who want drone exposure without betting the portfolio simply put a small amount into a mix of these names, or into a broad aerospace-defense fund, and keep the rest of their money diversified. None of these three routes is a recommendation; they are the common ways people approach the theme.

Step 4: Be honest about how speculative the pure-plays are

This is the step most drone hype skips, and it is the one that matters most. The commercial-drone and eVTOL pure-plays are exciting precisely because they are unproven, and that cuts both ways.

Many are small and pre-profit. A good number of these companies are small-cap, generate little or no profit, and in some cases little revenue. Their value rests on what they might become, not what they earn today.
The technology and rules are still unsettled. Commercial drone economics and eVTOL air taxis depend on regulation, certification, and demand that are still being worked out. Timelines slip, and a promising company can stall for reasons outside its control.
Prices can move violently. Speculative small-caps trade on news, sentiment, and funding announcements. Sharp drops of a large fraction of value are common, and some of these companies could fail outright. A total loss on a single name is a real possibility.
Exciting theme, hard investment. A theme being real does not make its stocks a good investment. Being clear-eyed that most pure-plays are speculative bets, not stable compounders, is the honest starting point.

None of this means you should or should not own them; it means going in with your eyes open. This is descriptive, not advice.

Step 5: Size the position small and diversify the rest

Because the speculative side of drones is so volatile, position sizing does more work here than stock picking. The discipline is boring on purpose.

Keep any speculative position small. Many people who choose to hold pre-profit drone or eVTOL names size the position so that even a total loss would not derail their overall plan. The more speculative the name, the smaller the sensible slice.
Separate the two halves in your head. An established defense name with drone revenue is a different risk from a pre-revenue eVTOL startup. Treating them as one bucket hides how much risk you are actually taking.
Hold a diversified core. Keep the bulk of your portfolio in a broad, diversified base so one speculative theme having a bad year does not define your results.
Do not chase the spike. Speculative names run and crash on headlines. Piling in after a big move is how investors get hurt. A drone tilt, if you want one, is a small, deliberate position, not a reaction to a rally.

There is no correct percentage, and this is not advice. With a theme this speculative, the point is to size it so a bad outcome is survivable.

Where Walnut fits

Drones are exactly the kind of theme where excitement outruns discipline, and that is where Walnut is useful. If you want a drone-themed basket, Walnut lets you build it, set target weights, and see how it would have tracked against a benchmark, so any speculative tilt has to earn its keep. It can also show how a small drone position fits alongside the rest of your holdings before you add more. You connect your real broker, chat through Claude, ChatGPT, or built-in AI, and place trades you approve yourself. Walnut does not tell you what to buy.

FAQ

How do I start investing in drones?

Open a brokerage account, then decide how you want exposure. There is no large dedicated drone ETF, so people usually choose between established defense and aerospace names that have drone revenue (such as AVAV, KTOS, or LHX), smaller and more speculative commercial-drone or eVTOL pure-plays (such as RCAT, ONDS, ACHR, or JOBY), or a broad aerospace-defense fund that holds drone makers alongside other businesses. Decide how much to invest, keep any speculative position small, and place the trade. Walnut is not an investment adviser; this is educational, not a recommendation.

What is the difference between defense drones and commercial drone or eVTOL stocks?

Defense-drone exposure usually comes through established aerospace and defense companies that already sell unmanned systems to governments and have real, recurring revenue. Commercial-drone and eVTOL (electric air-taxi) names are often much smaller, earlier-stage companies, many of which are pre-profit and still proving their technology, regulatory path, and demand. The defense side tends to be steadier; the commercial and eVTOL side tends to be far more speculative and volatile. Neither description is a recommendation to buy either.

Are drone stocks a good investment?

There is no way to say, and this page does not try to. Drones sit across two very different risk profiles: established defense contractors with diversified revenue, and small pre-profit startups whose value rests on technology and markets that are still developing. The speculative pure-plays can move dramatically in both directions and some may never reach sustained profitability. Whether any of this fits you depends on your goals, time horizon, and risk tolerance, which only you or a licensed professional can judge.

Is there a drone ETF?

There is no large, well-established fund that holds only drone companies. Some niche or thematic funds touch the space, but they tend to be small and can hold overlapping or loosely related names. The more common way to get diversified, indirect exposure is through a broader aerospace and defense ETF, which holds drone makers alongside jet, missile, and other defense businesses, so the drone exposure is diluted. This is descriptive, not a recommendation of any fund.

How much of my portfolio should be in drone stocks?

That is a personal decision, and there is no single right number. The honest framing is that most drone pure-plays are small, speculative, and volatile, so many people who choose to hold them keep the position small enough that a total loss would not derail their plan, and treat established defense names differently from early-stage startups. Sizing a speculative tilt so a bad outcome does not upend your whole portfolio is the disciplined way to think about it. Walnut is not an investment adviser and none of this is advice.

Does Walnut tell me which drone stocks to buy?

No. Walnut is not a registered investment adviser and does not tell you what to buy. It can help you see how a drone-themed basket would track against a benchmark, show how a small speculative position fits alongside the rest of your holdings, and place trades you approve yourself at your own broker. Every page here is descriptive and informational, not a recommendation.

From here you can see the individual names side by side in our best drone stocks guide, or explore the drones theme to see how a basket of these companies would have tracked against a benchmark.

Walnut is informational and is not a registered investment adviser. This page explains how drone stocks and drone exposure work; it is not a recommendation to buy, sell, or hold any security or fund. Many drone companies, especially commercial-drone and eVTOL pure-plays, are small, pre-profit, and highly speculative, and can be extremely volatile, including the possible total loss of your investment. Investing involves risk, including the possible loss of principal. Past performance does not indicate future results.
