Market Microstructure Ontology
6-Axis System Graph
System Overview
Prediction markets are no longer isolated betting environments.
They are evolving into structured financial systems defined by execution, liquidity, collateral, and participation architecture.
The system can be decomposed into six primary axes that define how prediction markets operate at a structural level.
Each axis isolates a different dimension of market microstructure, enabling comparison across execution design, capital efficiency, liquidity formation, and user interaction.
→ Market systems are decomposed into structural axes
→ Each axis defines a distinct layer of financial behavior
→ Together they form a unified microstructure graph
Architecture Summary
Two dominant system designs emerge across prediction market infrastructure.
Hyperliquid represents an integrated execution-native system, while Polymarket represents an application-layer participation system.
The difference is not functional but structural: one collapses financial primitives into a unified engine, the other distributes them across modular layers.
→ Execution-native systems unify financial primitives
→ Participation systems distribute functional layers
→ Architecture defines system optimization target
Hyperliquid System Model
Hyperliquid operates as a vertically integrated financial infrastructure system.
- Execution, liquidity, and collateral unified in HyperCore
- Machine-native API access
- Low-latency deterministic execution loop
- Shared state across instruments
This structure minimizes abstraction layers between market state and execution, optimizing for machine-speed trading systems.
→ Execution, collateral, and liquidity are unified
→ AI agents operate directly on core state
→ System optimized for execution efficiency
Polymarket System Model
Polymarket operates as a modular participation-layer prediction market system.
- External execution via API and wallet layers
- Modular settlement infrastructure
- UI-driven participation model
- Fragmented market-level state
This architecture prioritizes accessibility and probability discovery over execution efficiency.
→ Execution abstracted through external layers
→ Users interact via application interface
→ Market state distributed across modules
Structural Insight
The evolution of prediction markets reflects a shift in abstraction priorities.
Competition is no longer defined by liquidity depth or UI design, but by how deeply systems integrate execution, collateral, and pricing into unified infrastructure.
→ Infrastructure integration defines competitive advantage
→ Execution depth replaces UI as primary axis
→ Markets converge toward machine-native structures
Final System View
Prediction markets are converging toward programmable financial infrastructure.
Liquidity, collateral, and pricing are becoming unified execution primitives rather than separated system components.
→ Markets evolve into execution-native systems
→ Financial primitives become programmable layers
→ Microstructure becomes a graph of interacting axes
