Market Maker Technology: Engineering the Liquidity Layer of Exchange Platforms
Market makers provide the liquidity that makes prediction markets, sportsbook exchanges, and event contract platforms actually work. Without them, order books are empty and users cannot trade. Building or licensing market maker technology is the specific engineering discipline that determines whether an exchange platform is a functioning market or a well-designed empty room.










A market maker is an entity (or a piece of software) that continuously quotes buy and sell prices on a market and stands ready to trade at those prices. When a user wants to buy, the market maker sells. When a user wants to sell, the market maker buys. The market maker profits from the spread between the two prices and takes on inventory risk in return.
Without market makers, exchanges struggle to function. New markets have no natural buyers or sellers, and users looking to trade find no counterparties. Market makers fill this gap by providing continuous two-sided liquidity, at the cost of running an inventory position and managing the associated risk.
Market maker technology is the software that runs this operation. Pricing algorithms that determine what quotes to offer. Inventory management that tracks positions and limits exposure. Risk controls that pull quotes when the position gets too large. Execution logic that decides which orders to fill and which to skip. Each of these is an engineering component that has to be tuned for the specific market being traded.
We build market maker technology for operators of prediction markets, sportsbook exchanges, and event contract platforms. The engineering discipline is closer to trading system development than to gambling platform development. Getting it right requires people who have built and operated trading systems before.
Prediction markets face a specific liquidity problem: new markets are launched constantly, each starts with no organic buyers or sellers, and users looking to trade find empty order books. Without market maker participation, these markets die on the vine. With market maker participation, they become viable trading venues where organic user liquidity eventually emerges.
The economics of market making in prediction markets differ from equities or FX. Markets are shorter-lived (contracts settle at defined events rather than trading indefinitely). Volatility is often higher because news can dramatically shift implied probabilities. And the trading population is smaller and less sophisticated, which means market makers face less adverse selection risk than in mature financial markets.
Operators of prediction markets have three broad options for market maker participation. Run internal market makers as a first-party liquidity provider. Attract external market makers by offering favourable fees and technical infrastructure. Use automated market maker (AMM) protocols that pool user liquidity and price through algorithms rather than active market making. Each has trade-offs, and most operators end up combining multiple approaches.
We help operators design the market maker layer as part of the platform build. The decisions are consequential: they determine liquidity quality, operator risk exposure, and the economics of the platform. Getting the market maker strategy wrong is a common cause of exchange platform failure.
The commercial model for market makers on a prediction market platform
Market makers are running a business, not a favour. Any operator wanting market maker participation on their platform has to structure the commercial model to make it viable for the market makers.
The key economic inputs are fee structure, rebate mechanics, and inventory risk. Market makers typically receive rebates for providing liquidity (posting orders that other users trade against) and pay fees for taking liquidity (matching against posted orders). The net economics have to be positive after inventory risk and operational costs. Platforms that structure fees to squeeze market makers end up without market makers.
The technical infrastructure also matters. Market makers require API access with low latency, reliable market data feeds, and predictable execution behaviour. Platforms that treat market maker connectivity as an afterthought get lower-quality market makers, which means worse liquidity for retail users, which means lower platform revenue. The chain is direct.
Our work with operators on this includes designing the fee structure, engineering the technical infrastructure that market makers need, and in some cases building the market maker technology itself when the operator wants first-party liquidity provision as part of the platform strategy. The commercial model and the technology are tightly coupled decisions.
The build vs. license question applies specifically to market maker technology as it does to any platform component. The vendor market for market maker software is thin and specialised. A handful of trading system vendors offer market maker platforms, mostly designed for financial exchanges and adapted for other use cases with varying success.
Licensing works when the operator wants a proven system quickly and can accept the vendor’s constraints on customisation. It fails when the specific requirements of the platform (unusual contract types, novel pricing models, integrated risk management with other platform components) exceed what the vendor’s product can accommodate.
Building works when the operator has the engineering capability to develop and operate a trading system, or partners with a delivery team that does. The advantages are proprietary pricing IP, tight integration with the rest of the platform, and full control over the risk management model. The costs are the engineering investment (typically six to twelve months for a viable first version) and the ongoing operational burden of running a trading system.
Most operators pursuing exchange-style platforms end up building rather than licensing for market maker technology, because the specific integration requirements exceed what off-the-shelf products handle. We help operators evaluate the decision honestly and, when the answer is build, deliver the system with senior engineers who have built trading platforms before.
