About Market Making Games

At the Amsterdam Investment Club, we bring financial concepts to life with Market Making Games. Instead of abstract theory, participants dive into order books, Dutch auctions, and trading rounds to experience how markets work in real time. From estimating answers to earning profits as market makers or traders, the game blends learning with playful competition — perfect for beginners exploring finance or aspiring traders sharpening their skills.

Financial markets can feel intimidating, but they can also be a lot of fun to explore. At the Amsterdam Investment Club, we host Market Making Games to break down market concepts into interactive sessions. Instead of abstract lectures, we mix estimation games, Dutch auctions, and trading rounds to bring financial concepts to life.

Understanding the Order Book

At the heart of market making lies the order book: a table of buy and sell orders with corresponding prices and volumes. Market makers provide liquidity by posting both bids (buy offers) and asks (sell offers). The spread — the difference between buy and sell — represents the market maker's opportunity for profit.

Order Book Example

For example, in the order book below, if one wants to buy a stock, they would have to purchase at 3.296, as this is the lowest price someone is willing to sell for. If one wants to sell, this would happen at 3.288, as this is the highest price someone is willing to buy for. Market makers set out these orders to provide liquidity and to make profit without taking market risk, as they try to find the prices for which both sides get filled.

Scoring & Leaderboard

Points are awarded based on accuracy and profitability. Market makers profit from spreads, traders profit or lose depending on the final result. The final answer to the question (final price) is announced either after a certain time or after the market has set at a point where no more trades occur. At the end of the session, participants can check the leaderboard for current rankings.

Adding Complexity

While the core version of the game is simple, it can easily be made more challenging and realistic:

Probability & Randomness: Incorporating dice rolls, card draws, or probabilistic outcomes introduces uncertainty and risk management into the game.

More Difficult Problems: Instead of straightforward estimation, questions can involve layered calculations, statistical reasoning, or multi-step logic.

Advanced Instruments: Beyond basic bid/ask trading, the game can expand to include options, spreads, or other derivatives — mimicking real financial markets more closely.

This flexibility makes the game suitable for both beginners learning the basics and advanced players who want to test their strategic skills in more complex market environments.

Why Play Market Making Games?

Learn how real markets work in a hands-on way
Develop estimation and reasoning skills
Understand the roles of traders and market makers
Compete for points and rankings while having fun
Practice the skills as they are often played to get into trading firms

We always make it unique. For example, on September 23 we hosted a Jane Street Estimathon — a team-based contest that combines trivia, game theory, and mathematical thinking. Teams have 30 minutes to work on a set of 13 estimation problems, with the winning team being the one with the best set of estimates.
