Helm Core Concepts

Understand the instruments, mechanics, and vision behind the premier trading terminal for prediction markets.

Event Contracts

Helm is the premier trading terminal for prediction markets, prediction perpetuals, and AI agent assistants. Event Contracts are the core instrument of Helm—designed to let you go long on your conviction about clearly defined, binary (yes-or-no) future events.

How it works: Buy shares in the Yes or No outcome. Contract prices fluctuate in real time between $0.01 and $0.99 as new information and market dynamics evolve. Upon resolution, shares aligned with the final outcome settle at $1.00, while shares on the opposing side settle at $0.00.

Prediction Perpetuals

Helm is the first platform to function as a complete Perp DEX for predictions. In addition to traditional perpetual trading on crypto, users can go long or short on their predictions with leverage.

This creates thriving secondary perpetual markets around popular events—delivering continuous trading, greater flexibility, and maximum capital efficiency.

Market-Implied Probability

The trading price of each Event Contract represents the market’s consensus probability that the event will occur. This creates a transparent, incentive-aligned mechanism for discovering forward-looking expectations in real time.

Trading Fees — 1% Only on Realized Profits

Helm is built for zero friction. We believe you should only pay when your conviction proves correct.
