On May 2, 2026, Hyperliquid’s mainnet officially activated the HIP-4 protocol. Just four days earlier, leading prediction market Polymarket completed its CLOB V2 upgrade and migrated to pUSD. The deployment of two major upgrades within the same week is no coincidence. The launch of HIP-4 marks a real breakthrough in the boundaries between on-chain derivatives trading and prediction markets.
What HIP-4 Brings
On May 2, 2026, Hyperliquid deployed the HIP-4 protocol on its mainnet, officially introducing "outcome contracts" as a brand-new trading tool. The first batch of products are binary outcome contracts for same-day BTC settlement, allowing users to trade on whether the BTC price at a specified time will be above a certain level. Contract prices range from 0.001 to 0.999, reflecting the market’s pricing of the probability of the event occurring. Upon settlement, if the event occurs, the contract pays out 1; otherwise, it pays out 0. All contracts are fully collateralized with USDH. On launch day, over 6.05 million contracts changed hands, with a nominal trading volume of $6.2 million.
According to Gate market data, as of May 12, 2026, the HYPE token was quoted at $41.373, down 2.34% in 24 hours, with a market cap of approximately $9.862 billion. Over the past year, HYPE has risen about 66.28%.
HIP-4 is not simply a copy of Polymarket. Its core difference lies in outcome contracts being directly embedded into Hyperliquid’s trading engine, HyperCore, operating alongside perpetual contracts, spot, vaults, and automated strategies within the same system. This means prediction markets shift from being a standalone product to a "trading primitive" within Hyperliquid’s infrastructure—users can hold both a BTC perpetual long position and an event contract like "Will BTC break a certain price this week?" in the same account, using unified USDH collateral.
From Perp DEX to Multi-Asset Trading Platform
HIP-4 is the fourth in the series of Hyperliquid governance improvement proposals. To understand HIP-4’s positioning, it’s helpful to look back at the previous three proposals:
- HIP-1: Established the standard framework for the native token HYPE
- HIP-2: Introduced the super liquidity mechanism
- HIP-3: Launched on October 13, 2025, allowing third parties to deploy perpetual contracts independently after staking 500,000 HYPE, transforming Hyperliquid from a centralized listing hub into a neutral perpetual contract infrastructure layer
HIP-3 had a significant impact. Recently, HIP-3 markets hit an all-time high of $1.43 billion in open interest, more than 100 times growth since the first HIP-3 markets launched six months ago.
On February 2, 2026, the HIP-4 proposal was jointly written and officially released by Bedlam Research and John Wang, Head of Crypto at Kalshi. That same week, the proposal entered the testnet phase. After three months of testing, it went live on the mainnet on May 2.
Here’s a summary of the key timeline:
| Date | Key Event | Nature |
|---|---|---|
| October 2025 | HIP-3 mainnet launch, permissionless perpetual contract deployment | Critical infrastructure upgrade |
| February 2, 2026 | HIP-4 proposal officially released | New narrative launched |
| February 2, 2026 | HIP-4 testnet launch | Technical validation |
| April 28, 2026 | Polymarket completes CLOB V2 upgrade and pUSD migration | Competitor iteration |
| May 2, 2026 | HIP-4 mainnet launch | Core product launch |
| May 4, 2026 | First HIP-4 contract achieves $6.2 million daily trading volume | Market validation |
The Expansion Power of a Perp DEX Leader
Hyperliquid’s move into prediction markets isn’t a reckless extension—it’s built on a strong foundation in on-chain derivatives. Key data highlights its confidence in expansion:
Market share continues to climb. In March 2026, Hyperliquid’s share of total perpetual contract trading volume reached nearly 6%, up from about 3.5% a year earlier, with monthly trading volume close to $200 billion. Notably, this growth happened as overall platform trading volumes declined from their August 2025 peak, meaning Hyperliquid is genuinely capturing market share rather than simply benefiting from industry-wide growth.
On-chain competitors are falling behind. In decentralized perpetuals, dYdX’s market share dropped from 73% at the start of 2023 to single digits, with its token price plunging over 90%. GMX is publicly recruiting a CEO and shifting to a traditional leadership structure. DEX market share for platforms like Jupiter and Drift remains below 3%. Hyperliquid is now the only on-chain perpetuals platform with sustained growth, recently accounting for 44% of weekly DEX derivatives trading volume.
Strong industry foundation for prediction markets. In 2025, prediction market trading volume grew over 300%, reaching $63.5 billion.
Together, these figures point to a structural conclusion: prediction markets are experiencing explosive growth, and Hyperliquid is entering at precisely the right time, backed by its strong derivatives foundation.
Deep Dive: HIP-4 Mechanisms
Fully Collateralized Binary Contracts
HIP-4 outcome contracts are fully collateralized binary options. Contract prices float between 0.001 and 0.999, reflecting the market’s implied probability for specific events. Upon expiry, contracts settle at 1 (event occurs) or 0 (does not occur), based on oracle-determined outcomes.
Trading logic aligns with traditional prediction market user habits: buy long at price P, settle at 1 if the event happens, profit is 1 - P; if not, loss is limited to the entry cost. There’s no leverage or liquidation risk, and settlement currency is Hyperliquid’s native stablecoin USDH.
Staking Threshold for Market Creation
Creating a new prediction market requires staking 1 million HYPE tokens. This pricing mechanism is designed to prevent malicious market spam and create new lock-up demand for HYPE. Developers must specify the event name, settlement time, oracle data source, and may set a dispute window. After creation, the system enters a roughly 15-minute single-price call auction phase for order initialization and matching, then moves to continuous trading.
Four Structural Innovations
Trading primitive integration. Unlike Polymarket, which operates as a standalone prediction platform, HIP-4 treats outcome contracts as a trading primitive within the HyperCore engine. This allows outcome contracts to share the same order book, clearing system, and user account structure with perpetuals, spot, and vault products.
Composability. Users can trade perpetuals and bet on prediction markets within the same account, using unified USDH collateral. According to on-chain researcher Fleck, about 3.3% of Polymarket users are also active on Hyperliquid, but this group contributes roughly 12% of Polymarket’s total trading volume, indicating a strong real demand for unified multi-asset accounts among core traders.
Differentiated fee structure. HIP-4 charges zero fees for opening positions, with fees only on closing, burning, or settlement. In contrast, Polymarket charges up to 2% on profits, which can accumulate significant costs for high-frequency traders.
Permissionless market creation. Any user staking 1 million HYPE can create a prediction market without platform approval. On Polymarket, only approved market creators can launch new markets.
Comparative Perspective: Key Differences Between HIP-4 and Polymarket
The following fact-based comparison matrix outlines core differences in architecture, fee structure, and asset efficiency:
| Dimension | Hyperliquid (HIP-4) | Polymarket |
|---|---|---|
| Architecture | Outcome contracts as trading primitive in engine | Standalone prediction platform |
| Account system | Unified account for perpetuals, spot, and event contracts | Separate collateral for each market |
| Fee model | Zero fees to open, fees only on close/settlement | ~2% fee on profits |
| Asset efficiency | Cross-margin, unified USDH collateral | Isolated collateral per market |
| Composability | Can combine with perpetuals, spot, strategies | Closed ecosystem, limited composability |
| Token incentives | HYPE token lets users share platform growth | No native token launched yet |
| Market creation | Permissionless with 1 million HYPE staked | Only approved creators can launch markets |
| Regulatory strategy | Offshore operations, US users restricted | Registered with CFTC, rebuilding US compliance |
Both models have strengths and weaknesses. Polymarket has spent years developing its compliance pathway, with advantages in on-chain settlement transparency, information aggregation, and mainstream media citations. Hyperliquid leverages its technical performance and user base in derivatives trading to enter with higher asset efficiency and lower trading costs. This differentiated competition is driving the prediction market sector toward greater efficiency and composability, ultimately benefiting users.
Three Distinct Market Interpretations
HIP-4’s launch has sparked at least three sharply defined viewpoints in the market:
Viewpoint One (Bullish): Prediction markets will fundamentally transform through composability. Arthur Hayes, CIO of Maelstrom, asserts that Hyperliquid’s model can use its native HYPE token to economically reward users—an advantage Polymarket and Kalshi currently lack. He sees HYPE as the key differentiator for HIP-4: users holding HYPE can directly benefit from platform growth.
Viewpoint Two (Cautious): HIP-4 remains in the validation phase and hasn’t proven scalability. HIP-4’s first product is a relatively simple daily BTC price threshold contract. For more complex event types—political elections, sports, macroeconomic data releases—its oracle settlement, dispute resolution, and liquidity depth have yet to be fully tested in practice. The $6.2 million first-day trading volume is still very early, given prediction markets now see monthly volumes in the tens of billions.
Viewpoint Three (Trend-Focused): The endgame is a multi-asset trading platform. Bernstein’s May 4 report notes that while retail has long dominated prediction markets, institutional investors are now entering, and contract types are evolving from single-event forecasts to a "perpetual + spot + prediction" multi-asset structure. Polymarket has announced perpetual contracts "coming soon," and Kalshi has completed its first custom institutional block trade. The industry’s final form may be platforms offering similar product matrices, with competition shifting from "category differentiation" to "execution efficiency and liquidity."
Each view has its own logic, and it’s too early to say which will prevail. What’s clear is the prediction market industry is undergoing fundamental structural evolution, with HIP-4 as a key variable in this transformation.
Industry Impact: Hyperliquid’s Multi-Asset Platform Strategy Takes Shape
Examining HIP-4 within Hyperliquid’s broader strategy reveals a clear evolutionary path:
From perpetuals to multi-asset trading infrastructure. HIP-1 established token standards; HIP-2 solved liquidity; HIP-3 transformed perpetuals from "platform custody" to "infrastructure"—allowing anyone to deploy their own contract markets. HIP-4 extends this logic to prediction markets. Hyperliquid’s product matrix now covers perpetuals, spot, commodities, pre-IPO equity, and prediction markets—evolving from a single Perp DEX to a comprehensive on-chain trading infrastructure.
Strategic value of asset crossover. Non-crypto asset trading volume continues to rise as a share of overall activity on Hyperliquid. Commodities like oil now trade 24/7, offering structural advantages traditional financial infrastructure can’t match—traders no longer need to pay for CME weekend gap risk. HIP-4 further expands this boundary: event contracts aren’t directly tied to financial assets, but trade "uncertainty" itself.
Prediction markets as financial infrastructure. In October 2025, Intercontinental Exchange (ICE), parent of NYSE, invested $2 billion in Polymarket, marking prediction markets’ move from gray area to mainstream finance. Hyperliquid’s HIP-4 enters this macro trend from the perspective of "trading infrastructure" rather than "single prediction app," fundamentally differing from existing platforms.
HYPE token value capture logic. HIP-4 adds a core use case for HYPE: every prediction market creation requires staking 1 million HYPE. As market activity grows, this drives ongoing deflationary pressure—Hyperliquid destroyed over 14 million HYPE in 2025 alone, with its buyback and burn mechanism continuously absorbing supply.
Conclusion
With HIP-4, Hyperliquid elevates prediction markets from a standalone application to a trading engine primitive. The significance of this architectural innovation is that it doesn’t compete head-on with Polymarket in user penetration or information aggregation, but instead opens a new front in asset efficiency and composability.
As of May 12, 2026, HYPE trades at $41.373 with a market cap of about $9.862 billion. HIP-4 brings new use cases and demand lock-in for HYPE, though full value realization will take time. The prediction market industry is leaping from tens to hundreds of billions, and Hyperliquid enters with high-performance L1, a vast on-chain perpetual user base, and a composable architecture. Whatever the outcome, once the boundary between on-chain derivatives and prediction markets is broken, the competitive logic for the entire sector is fundamentally rewritten.
