HIP-4: Outcome Trading

HIP-4, officially called "Outcome Trading," was unveiled by Hyperliquid on February 2, 2026. It introduces fully collateralized outcome contracts — a new financial primitive that enables prediction markets, options-style derivatives, and event-driven trading directly on HyperCore. HYPE rallied over 10% on the announcement alone, signaling strong market interest in the expansion.

The core innovation is simple but powerful: outcome contracts let traders take positions on the result of an event (will something happen or not?) or on whether an asset will finish above or below a certain price by a certain date. Unlike perpetual futures, outcome contracts are fully collateralized — participants pay the maximum potential cost upfront. There is no margin trading, no leverage, and no liquidations. You cannot lose more than you put in.

An outcome contract defines a binary or bounded event. For a binary contract, the price trades between 0 and 1 (representing 0% to 100% probability). If you think an event is likely, you buy at the current price — say 0.65 — and if the event occurs, the contract settles at 1.00, netting you 0.35 per contract. If the event does not occur, it settles at 0.00 and you lose your 0.65. The maximum loss is always known upfront.

Outcome contracts run natively on HyperCore, sharing the same trading engine and order book infrastructure as Hyperliquid's perpetual and spot markets. This means the same low-latency execution, the same on-chain transparency, and the same self-custody guarantees. Unlike standalone prediction platforms that use separate liquidity pools, HIP-4 contracts benefit from Hyperliquid's unified trading ecosystem.

The design also supports dated markets and non-linear payoff structures beyond simple binary events. This opens the door to options-like products — defined-risk contracts with known maximum payoff and loss at the time of entry, all without the complexity of traditional options pricing, Greeks, or liquidation mechanics.

HIP-4 supports a broad range of event types: economic data releases (will inflation come in above or below consensus?), crypto milestones (will Bitcoin reach a certain price by a certain date?), sports outcomes, elections, and more. The contract structure is general-purpose — if an event has a verifiable outcome, it can be structured as an HIP-4 contract.

As of early 2026, outcome trading is live on testnet with a curated set of markets before moving toward permissionless listings. The expectation is that HIP-4 will follow a similar trajectory to HIP-3: starting with a curated set of high-quality markets, then opening up to permissionless deployment as the infrastructure matures.

The prediction market space is growing rapidly, with platforms like Polymarket and Kalshi gaining significant traction. HIP-4 differentiates itself in several ways. First, outcome contracts run natively on HyperCore's high-performance order book rather than in separate liquidity pools, which means tighter spreads and faster execution. Second, traders who already use Hyperliquid for perps and spot trading can access prediction markets from the same interface and the same account — no bridging funds to a separate platform.

Third, HIP-4 benefits from composability with the rest of the Hyperliquid ecosystem. HyperEVM smart contracts can interact with outcome contracts, enabling automated strategies, structured products, and portfolio-level risk management across perps, spot, and prediction markets from a single on-chain account. This kind of cross-product composability does not exist on standalone prediction platforms.

HIP-4 extends Hyperliquid beyond perpetuals and spot trading into an entirely new product category. Prediction markets alone represent a multi-billion-dollar opportunity, and the options-like payoff structures add even more surface area for traders and builders. Each new market type generates trading activity that feeds into Hyperliquid's fee revenue and the Assistance Fund HYPE buyback mechanism.

For the broader ecosystem, HIP-4 makes Hyperliquid more useful as a general-purpose financial platform — not just a place to trade crypto leverage, but a venue for expressing views on real-world events with defined risk, instant settlement, and full on-chain transparency. Combined with HIP-3's permissionless perps and HyperEVM's smart contract capabilities, HIP-4 moves Hyperliquid closer to becoming a universal trading layer.
