I'm looking for the best free-to-play stock market prediction game.

If you want a free-to-play experience that feels like a game—complete with leaderboards, custom competitions, and virtual cash—several top platforms stand out depending on whether you want casual competition or deep charting mechanics.

• MarketWatch Virtual Stock Exchange: Great for a casual, highly accessible browser-based game. You can instantly set up or join public/private games, trade stocks and options with virtual money, and track leaderboards without downloading any software.
• HowTheMarketWorks: Excellent for a feature-rich, gamified classroom or group experience. It gives you $100,000 in virtual cash, real-time pricing, and lets you build custom contests to challenge friends with specific rules or starting balances.
• Wall Street Survivor: Built heavily with a learning-first "game" progression in mind. It pairs a virtual $100,000 portfolio tracker with interactive lessons, monthly trading contests, and prizes.
• Webull Paper Trading: If you want a game that uses real, professional-grade trading tools, Webull offers a completely free simulator loaded with up to $1,000,000 in play money so you can test real-time strategies on mobile or desktop.

Player Experiences

MarketWatch's browser-based simulator lets you practice without installation, with stocks and options in a free, user-friendly format.

“We offer a free stock market game featuring real-time stock prices and rankings that allows users to learn about the stock markets and practice investing in stocks, ETFs, bonds, and mutual funds.”

Are you looking to play casually against friends in a private league , or do you want a simulator focused on day-trading with real-time charts?

If by “stock market prediction game” you mean a free game where you make stock picks and compete against other players, my top choice right now is Wall Street Survivor.

🏆 Best overall: Wall Street Survivor

• Free: You get $100,000 in virtual cash.
• Real markets: Trade U.S. stocks, ETFs, options, and crypto using real market data.
• Actually game-like: You can join or create contests and compete on leaderboards rather than simply paper-trading alone.
• Learning built in: It combines the simulator with bite-sized investing courses.
• Current competitions: Its Fall Into Investing contest starts September 1, 2026, with $500 in prizes and no credit card required.

Other good choices

• StockTrak — Better if you want a more realistic trading simulator with stocks, options, futures, bonds, forex, crypto, and 50+ global exchanges. Its individual practice offering includes free virtual trading.
• JagSim — Interesting if you want a simpler, competition-oriented experience with a permanent virtual portfolio and leaderboard.

My pick: Start with Wall Street Survivor. It has the best combination of free + competitive + educational + realistic enough to be useful.

One caveat: these games can teach you whether your strategy works, but they can't reliably predict which stocks will go up. Even sophisticated AI stock-picking systems continue to struggle with consistently beating the market.

If you mean a game where you compete specifically against AI predicting stock prices (rather than a normal paper-trading game), I can find the best ones for that too.

When looking for the best free-to-play stock market prediction or simulation game, the right choice depends on whether you want a fantasy-style social competition , an educational tool , or a pro-level simulator using real market data.

The top free options available span several distinct categories:

• MarketWatch Virtual Stock Exchange : Great for custom social leagues. You can start or join public/private games, set custom starting cash ($10,000 to $1 million), choose specific asset classes, and compete against friends or strangers using real-time pricing data.
• Wall Street Survivor : Built like a fantasy league meets an RPG. It uses real stock price tracking and virtual cash, but pairs the gameplay with video lessons, quests, and achievements to help beginners learn the ropes without feeling intimidated.
• Investopedia Stock Simulator : One of the cleanest, most feature-rich simulators on the web. It gives you a realistic $100,000 virtual portfolio, allows you to trade global equities and ETFs, and tracks detailed leaderboards and analytics.
• thinkorswim (by Charles Schwab) : If you want to skip the "game" feel and practice real predictive analysis, thinkorswim's paper trading feature ($100,000 in virtual funds) offers professional-grade charting and live market feeds.
• HowTheMarketWorks : Excellent for structured learning, custom classroom/group competitions, and tracking real-world stock and ETF fluctuations.

To help narrow down the best fit, tell me:

• Are you looking for a casual game to play with friends (like a private league) or a solo tool to learn technical analysis?
• Do you prefer a mobile app or a desktop browser experience?

If by “stock market prediction game” you mean a game where you pick stocks with fake money and compete based on how well your picks perform, my top choice right now is Wall Street Survivor.

🏆 Best overall: Wall Street Survivor

• 100% free to start; no credit card required.
• You get $100,000 in virtual cash.
• Uses real-time market data for U.S. stocks and ETFs, plus options and crypto.
• You can compete on leaderboards, join contests, or make private games with friends.
• It has built-in investing courses, so you're not just randomly guessing stocks.
• There are even free contests with real prizes. For example, its September–October 2026 contest has $500 in Amazon gift-card prizes.

Other good choices

MarketWatch's Virtual Stock Exchange is particularly strong if you want to create a custom competition, while Investopedia's simulator supports things like margin, short selling and options.

My recommendation: Start with Wall Street Survivor. If your goal is specifically to test “Can I predict which stocks will outperform over the next week/month?”, rather than simply practice trading, I can narrow this down to the best prediction-style game for that exact format.

If you want a free-to-play stock market prediction game or simulator that uses real market data, lets you compete against others, or teaches you the ropes without risking actual capital, several top platforms stand out:

• Investopedia Stock Simulator : Widely regarded as one of the best for absolute realism. It gives you virtual cash (typically $100,000) to trade real-time stocks, ETFs, and options. You can trade solo or join public/private competitions with hundreds of thousands of other users.
• MarketWatch Virtual Stock Exchange : A fast, browser-based stock market game where you can build custom games, set your own starting virtual cash, and invite friends, coworkers, or classmates to battle for the top spot on the leaderboard.
• Wall Street Survivor : Blends a fantasy stock market game with structured, bite-sized financial courses. It features a virtual portfolio with $100,000 in play money alongside monthly contests where participants can compete.
• How The Market Works : Highly gamified and heavily used by schools and investment clubs. It provides real market data, custom rule-setting for contests, and a large built-in library of educational lessons and progress tracking.
• The Trading Game : A mobile-centric app available on iOS and Android that turns prediction and chart-reading into a more direct game format, featuring 1v1 trading battles, quizzes, and offline trend-prediction challenges.

Are you looking to play casually against friends in a private league , or do you want a serious professional simulator to test real-world technical analysis strategies?

If by “stock market prediction game” you mean a game where you use virtual money to pick stocks, compete, and see whether your predictions beat other players, my top pick is:

🏆 Best overall: Wall Street Survivor

• 100% free — no credit card required.
• Start with $100,000 in virtual money.
• Uses real-time market data for stocks, ETFs, crypto, and options.
• Has leaderboards, monthly contests, and private games you can create with friends.
• Also includes educational material, so it works as both a game and a learning tool.

Why I'd choose it: It has the best combination of game/competition + realistic market data + learning. If your goal is to actually test whether your stock-picking instincts are good, this is probably the strongest free option.

🥈 Best if you want something more game-like: Tradicted

Tradicted is explicitly built as a free stock market game, with $100,000 in virtual cash, leaderboards, real historical market data, streaks, win rates, and trading analytics. It's available on iOS and Android.

🥉 Best for a serious simulation: Stock Market Challenge

It's a simpler, older-school experience, but it's genuinely free and lets you compete in weekly, monthly, and long-term rankings, as well as create private competitions with friends.

🎮 Most interesting if you want an actual game

This one is different: rather than simply mirroring the real stock market, it simulates an entire economy. You trade 108 companies across 12 sectors, compete against AI traders, and can even take companies public. It runs in your browser with no account required.

My ranking:

One important distinction: none of these can actually predict the stock market for you. They're prediction games in the sense that you make forecasts/picks and get scored on how they perform.

If you want, I can also find you the best one specifically for predicting which stocks will go up/down over 1 day, 1 week, or 1 month—which is a somewhat different category of game.

When looking for the best free-to-play stock market prediction game or simulator, the "best" choice depends on whether you want a pure educational game with leaderboards, a realistic paper-trading platform mirroring real-time Wall Street, or a gamified mobile app with built-in lessons.

The top free options available are categorized below by their play style:

Best for Gamified Learning & Mobile Play

• The Trading Game (Stock Simulator): Highly rated on mobile app stores, this app treats stock trading like an actual game. It features real-time market data across global stocks, crypto, and commodities, 1v1 trading battles against friends or AI, quizzes to test your chart-reading skills, and interactive bite-sized lessons.
• Stock Market Simulator Game (by Three Investeers): Gives you $100,000 in virtual cash to trade over 200 assets with prices updating multiple times per second. It includes a competitive weekly fantasy leaderboard and a streamlined "trading school" course.

Best for Competitive Fantasy Leagues & Classrooms

• MarketWatch Virtual Stock Exchange (VSE): A classic, completely free web-based platform. You can join public games or set up a custom private game for friends, coworkers, or students with custom starting cash, rules, and timelines.
• How the Market Works: Widely used in schools, this platform lets you build a virtual portfolio and compete in public or private contests using real-world stock pricing data.

Best for Real-World Brokerage Simulators (No Risk)

• Webull Paper Trading: If you want a simulation that feels 100% authentic rather than "arcade-like," Webull offers a robust paper trading feature with virtual money inside a professional-grade interface. You get access to live charts, technical indicators, and order types without risking a penny.
• Thinkorswim (by Charles Schwab/TD Ameritrade): Features "PaperMoney," widely considered the gold standard of professional trading simulators. It uses real market data and professional analysis tools, though the interface has a steeper learning curve than mobile games.

Are you looking for something casual and gamified on your phone (like quizzes and short rounds), or do you want a realistic simulator to practice actual trading strategies?

If by “stock market prediction game” you mean pick stocks, make trades with virtual money, and compete against other players, my top pick is HowTheMarketWorks.

🥇 Best overall: HowTheMarketWorks

• Starts you with $100,000 virtual cash
• You can create or join private competitions with friends
• Has leaderboards, so there's an actual competitive/game element

Other good choices

Tradicted is particularly interesting if you want something quick and game-like: it gives you $100K virtual money, uses real historical market data, tracks performance metrics, and has leaderboards.

If your goal is specifically “I want a game where I predict whether stocks will go up or down and compete for a leaderboard”, rather than a conventional paper-trading simulator, I’d pick Tradicted. If you want friends/classmates competing over weeks or months, pick HowTheMarketWorks.

The best free-to-play stock market prediction games and simulators depend on whether you want a competitive social game , an educational mobile app , or a pro-grade paper trading platform.

If you want to narrow this down, tell me:

• Are you looking for something to play on mobile (iOS/Android) or desktop/web?
• Do you want to compete against friends in a private league, or practice solo trading?

If by “stock market prediction game” you mean a game where you make predictions/trades with virtual money and compete based on how well you do, my top pick right now is Wall Street Survivor.

🥇 Best overall: Wall Street Survivor

• Free to play with $100,000 in virtual cash.
• Uses real-time market data, so your decisions are tied to actual market movements rather than a completely fictional economy.
• Trade stocks, ETFs, options and crypto.
• Has leaderboards and monthly contests, making it genuinely game-like.
• You can create private competitions with friends.
• Also includes free educational material, which is useful if you're trying to improve your prediction ability rather than simply gamble on price movements.

🎯 If you specifically want prediction, not trading

WALLSTREEK is interesting. It's a very simple daily prediction game: before the market opens, you predict whether the Dow, Nasdaq and S&P 500 will go up or down, then try to build a streak. It's free and doesn't require money.

That's probably closer to what you mean by a prediction game.

Other interesting options

StockLeague is particularly worth checking out if you want something that feels more like fantasy football: leagues, drafts, 1v1 duels, rankings, and real market prices. A July 2026 developer post describes it as completely free with no ads/paywalls.

My recommendation: start with WALLSTREEK if your goal is “Can I actually predict the market?” Start with Wall Street Survivor if your goal is “Can I build a portfolio that beats everyone else?”

If you tell me whether you want PC/browser, iPhone, or Android, I can narrow it down to the 3 most fun free games rather than just simulators.
