What Is a Stock Simulation Game?
A stock simulation game — sometimes called a stock market game or trading simulator — lets you buy and sell stocks with fake money instead of real cash. You get a virtual balance, trade fictional or real-world tickers, and watch a portfolio rise and fall exactly like it would in a real brokerage account, minus the risk.
That makes them a genuinely fun way to learn the ropes: go all-in on a bad idea, panic-sell at the worst possible moment, or hold through a crash, and the only thing you lose is time. Whether you're a complete beginner, a student in a personal finance class, or just want to test a theory before risking real money, this guide compares the best free options for 2026 — including a few built specifically for high school and middle school classrooms.

Information current as of August 2026 — please check each program's official site for the latest details and eligibility requirements. The Stock Market Game, HowTheMarketWorks, and MarketWatch Virtual Stock Exchange are independent, unaffiliated programs mentioned here for comparison.
Moshimo StockSimRecommended!Launched in 2026, Moshimo StockSim is a newer entrant that uses AI-driven news generation and other modern tech. Every player shares the same virtual market, and other players' trades and news move prices. It's playable right in your browser, and fictional companies mean you can practice without holding back. More detail in the next section.
A curriculum-based investing simulation from the SIFMA Foundation, used by nearly 20 million students in grades 4-12 since 1977. Classes manage a hypothetical $100,000 portfolio of real stocks, bonds, and funds, competing individually or in teams, with lesson plans and teacher resources built in. Access typically runs through a registered teacher or school.
A free stock market game built specifically for classrooms, with real-time data on real stocks and ETFs. Teachers get admin tools like trade-note requirements and progress reporting, plus a library of 50+ lessons, while anyone can also join public contests without a class.
A free trading simulator from MarketWatch that uses real, live stock and ETF prices. Anyone can create a public or private game and invite others to compete, which has made it a long-running favorite for classroom contests and casual competitions between friends.
Alternatives to The Stock Market Game (SIFMA)
The Stock Market Game, run by the SIFMA Foundation, is one of the most established investing programs for schools — but it's built around a semester-long classroom curriculum, and you typically need a teacher or school to register you before you can play. If you'd rather start trading today, without waiting on a registration process, here's where to look instead.
- ●Want to start right now, with no teacher account or sign-up? Moshimo StockSim puts you in a live, shared market instantly, right in your browser.
- ●Want real, live stock prices with public contests anyone can join? HowTheMarketWorks and MarketWatch Virtual Stock Exchange both let you jump into an existing game.
- ●Need a full curriculum with lesson plans and gradebook-style tracking for a class? The Stock Market Game is still the most established option if your school can register you.
Moshimo StockSim is the fastest option — it's a free, browser-based game with a shared live market you can join immediately, no registration or classroom required. HowTheMarketWorks and MarketWatch Virtual Stock Exchange are also open to the public and use real stock data, if you'd rather trade real tickers.
Best Stock Market Simulator for High School & Middle School
"Best" depends on who's asking. A teacher setting up a semester-long unit needs different tools than a student who just wants to compete with classmates this week. Here's how to pick:
- ●Teaching a formal personal finance or economics unit with lesson plans and assessments? The Stock Market Game is purpose-built for this, with resources for grades 4-12.
- ●Want real stock data and teacher oversight (trade notes, progress reports) without a semester-long commitment? HowTheMarketWorks offers classroom tools plus public contests.
- ●Want a dedicated classroom tool that doesn't require a district registration? Moshimo StockSim's School Mode lets a teacher create a private room, control the market's pace for the whole class, and see every student's portfolio — free, with no signup process for students.
For middle school and younger high school students especially, Moshimo StockSim's fictional companies can be an advantage: there's no risk of confusing a practice trade with a real brokerage account, and news-driven storylines make price moves easier to follow than raw real-world market data.
Yes — School Mode is built specifically for this. A teacher creates a private classroom room and gets a join code, students join anonymously with no email or app install, and the teacher controls a 'time machine' that advances the market in sync for the whole room. It isn't a formal curriculum program like The Stock Market Game, but it's a free, ready-to-run way to add a live trading unit to a personal finance or economics class.
A dedicated classroom mode: teachers create a free private room and get a join code, students join in seconds with no account setup, and the teacher can pause, rewind, or advance the market together with the whole class while tracking every student's portfolio.
What Makes Moshimo StockSim Different
Moshimo StockSim is a stock trading simulation where every player shares the same virtual market. It's not a solo experience — other players' trades and dynamically generated news move the market, giving you the tension of a real trading floor.
- ●Over 200 fictional companies listed across Japan and the US
- ●A 'story arc' system that ties news events to price movement
- ●Sectors spanning AI/semiconductors, finance, EVs, food & retail
It's a game, not a real brokerage — no real money is ever involved. It's free to download with no in-app purchases, making it easy to keep coming back.
FAQ
Yes, it's completely free with no in-app purchases. Everything is played with virtual funds.
No. It's a game, not a real brokerage, so there's no deposit or account opening required.
It uses fictional companies and puts every player in the same shared market — other players' trades and generated news move prices. That's a different kind of realism than apps that mirror real-world price data one-to-one.
You can start right away in your browser, free. iOS and Android apps are also available if you'd rather play on your phone.
Who Should Try It
- ●Beginners who just want to get a feel for how markets work
- ●Learners who want to test book knowledge in practice
- ●Anyone who's been putting off investing because it feels intimidating
A zero-risk environment is a low-pressure way to get comfortable with market movement first, then decide later whether opening a real brokerage account makes sense for you.
Why Practicing in a Game Helps
Zero risk to experiment with
The biggest benefit is zero risk. Since no real money is on the line, mistakes cost nothing financially. Buying at the wrong time, panic-selling on a dip — every misstep becomes a lesson you can carry forward instead of a real loss.
Realistic price action
Well-made simulations also model price movement realistically, reacting to news, earnings, and overall market mood. That intuition for how a stock responds to a headline is hard to get from a textbook alone.
Terminology that sticks
Terms like PER, PBR, market orders, and limit orders also stick better when you encounter them while actually using the app, rather than memorizing a glossary in isolation.
