Summary
Onyx Terminal is a low-latency trading terminal purpose-built for Polymarket, addressing the critical gap between prediction market infrastructure and professional trading needs. While Polymarket has grown to process billions in volume, its native web interface was designed for retail users and lacks essential execution tools that professional traders require.
The Problem It Solves
Polymarket's native interface suffers from three critical limitations for serious traders: UI latency that causes slippage during fast-moving events, absence of stop-loss functionality, and lack of sophisticated order management tools. When trading volatile events—elections, court decisions, market-moving announcements—every millisecond of click-latency translates to potential losses.
What Onyx Provides
Onyx Terminal delivers a Bloomberg Terminal-like experience for prediction markets. Key capabilities include:
- Low-latency execution: Minimizes the delay between decision and order placement
- Stop-loss orders: Risk management tool notably absent from Polymarket's native UI
- Advanced position sizing: Tools for calculating and managing appropriate trade sizes
- Professional risk management: TradFi-grade approaches to portfolio and exposure management
Architecture and Access
The terminal connects to Polymarket's CLOB (Central Limit Order Book) on Polygon. Users maintain self-custody through their own wallets—Onyx is an execution layer, not a custodial service. This architecture means traders keep control of their funds while gaining access to professional tooling.
Use Case
Onyx is built for traders who treat prediction markets as a serious asset class. This includes: professional prop traders diversifying into event risk, crypto-native traders expanding beyond DeFi, and sophisticated retail traders frustrated by basic exchange interfaces. The terminal is particularly valuable during high-volatility events where execution speed and risk controls matter most.
Competitive Position
As prediction markets mature and attract institutional interest, tooling like Onyx represents the infrastructure layer needed to support professional capital. It fills a similar role to what trading terminals did for traditional equities and crypto—turning a retail-accessible market into something professionals can trade at scale.

How People Use Onyx Terminal
Election Night Trading with Risk Controls
85%Election nights produce extreme volatility as results come in state by state. A trader wants to actively manage positions as data flows, but cannot manually watch every market or react fast enough with retail tools. They need stop-losses to protect capital if the election swings unexpectedly, and low-latency execution to capitalize on breaking county results.
Scalping High-Volatility Event Markets
80%Major events—FOMC decisions, court rulings, product launches—create rapid price movements in related prediction markets. A scalper wants to capture these moves with tight risk management, entering and exiting within minutes or seconds. They need low-latency execution to get filled before prices move and stop-losses to cap losses when wrong.
Portfolio Risk Management Across Markets
70%A trader holds positions in 20+ prediction markets across politics, economics, and culture. They need to understand aggregate exposure, correlation risk, and capital efficiency. Individual market interfaces make this impossible—they need a terminal that shows portfolio-level metrics and enables coordinated risk management.
Transitioning from Crypto to Prediction Markets
80%A DeFi trader wants to expand into prediction markets but finds Polymarket's interface lacking compared to dYdX or GMX terminals they're used to. They need familiar tooling—order books, stops, position tracking—to translate their crypto trading skills to a new asset class.

Rule of thumb
Use Onyx Terminal if you're trading prediction markets seriously—managing multiple positions, needing stop-losses, or trading high-volatility events where execution speed matters. Stick with Polymarket's native interface for casual bets, single-market positions, or if you're just exploring prediction markets. Onyx is a power tool for power users; the native UI is fine for everyone else.
