What is HIP-4 on Hyperliquid?

HIP-4 is Hyperliquid's outcome market standard. It adds binary event contracts that trade from 0.001 to 0.999 and settle in USDC at 0 or 1, alongside the exchange's perpetuals and spot markets in one unified margin account. It went live on mainnet on May 2, 2026.

Are Hyperliquid prediction markets regulated?

No. Hyperliquid is an onchain venue and is not a CFTC-regulated designated contract market the way Kalshi is. The CLARITY Act, which could create a regulatory pathway, passed the Senate Banking Committee on May 14, 2026 and remains pending.

How are Hyperliquid outcome markets settled?

By validator vote. Validators publish canonical markets using automated newsfeeds and resolve them onchain, with no external oracle. That differs from Polymarket, which uses the UMA optimistic oracle, and from Kalshi, which settles against CFTC-certified sources.

Can you use leverage on HIP-4 markets?

No. HIP-4 outcome contracts are fully collateralized, with no leverage and no liquidations. Your maximum loss is the price you paid to enter. That is different from the rest of Hyperliquid, where perpetuals are leveraged instruments.

How much does it cost to trade Hyperliquid prediction markets?

Opening a position costs nothing. Fees apply only on closing, burning, or settling, and were waived entirely during the testing period. Treat zero fees as promotional rather than permanent when you price a strategy.

Who can create a market on Hyperliquid?

Currently Hyperliquid validators control deployment. A proposed permissionless model would let anyone staking 500,000 HYPE deploy markets from approved templates, earning up to 50% of their trading fees and risking slashing for incorrect or late settlement.

Hyperliquid Prediction Markets: How HIP-4 Works

A Hyperliquid prediction market is an HIP-4 outcome contract: a binary claim on a real-world event that trades between 0.001 and 0.999 and settles in USDC at either 0 or 1. Buy YES at 0.40, and if the event happens you collect the remaining 0.60. There is no leverage and there are no liquidations, so the most you can lose is what you paid.

What makes HIP-4 different from a perp?

Everything else on Hyperliquid is a leveraged instrument. HIP-4 is not. The contract is fully collateralized, the maximum loss is the entry cost, and settlement is binary rather than continuous.

The structural advantage is the margin account. Outcome positions sit in the same unified margin as perpetuals and spot, so a trader hedging an event against a perp position is not posting collateral twice. On Polymarket and Kalshi that margin is isolated.

How does a Hyperliquid market get settled?

Validators settle it. There is no external oracle. Hyperliquid validators publish canonical markets using automated newsfeed software, then vote on chain to deploy and resolve them, which makes the whole loop native to the chain.

That is a genuine design tradeoff, not a free win. Polymarket routes disputes through the UMA optimistic oracle, and Kalshi settles against CFTC-certified sources. Hyperliquid's model is faster and has fewer moving parts. It also concentrates resolution authority in the validator set, which is the thing to understand before you size a position.

What do Hyperliquid prediction markets cost?

Opening a position is free. Fees apply only when you close, burn, or settle a contract, and per Galaxy's HIP-4 research they were still waived entirely during the testing period.

Treat that as promotional. Fee schedules on a new venue change, and a strategy that only works at zero fees is not a strategy. Price the trade at the fees you expect to pay in six months, which is the same discipline that decides whether a cross-venue spread is real.

How much volume does HIP-4 actually have?

Enough to matter, and not enough to lead. Outcome markets went live on Hyperliquid mainnet on May 2, 2026 with Bitcoin price binaries, then expanded on May 25 to validator-published markets including the June Fed rate decision and May CPI.

By day 25, Galaxy measured HIP-4 at 20.1% of combined Bitcoin prediction-market daily volume: $2.38M against Polymarket's $9.46M. For a venue less than a month old that is a real foothold. It is also a reminder that depth, not headline price, is what fills your order.

Who can list a market on Hyperliquid?

Today, validators. Next, anyone who can post the bond. Hyperliquid has proposed permissionless deployment where a deployer stakes 500,000 HYPE to list markets from validator-approved templates, which Crypto Briefing valued at roughly $31.1M at a HYPE price of $62.25.

The bond is the enforcement mechanism. A deployer who settles an outcome incorrectly, or leaves a market unsettled for more than a week, can be slashed. In exchange they are expected to earn as much as 50% of the trading fees their markets generate. It ships to testnet before mainnet.

What are the risks?

Regulatory. Hyperliquid is not a CFTC-regulated venue. The CLARITY Act cleared the Senate Banking Committee on May 14, 2026 and is still pending, and CME Group and ICE have reportedly pushed regulators to scrutinize the platform.
Resolution. Validator voting resolves markets. Read how a specific market defines its settlement condition before you trade it.
Liquidity. A young book means the spread you see may not be the spread you get. Check depth, not just the top of book.
Access. Confirm the venue is available in your jurisdiction.

None of this is financial advice, and prediction markets carry real risk of loss.

Where does Kairos fit?

A new venue is a new price for something you can already trade somewhere else. When the June Fed decision lists on Hyperliquid, on Polymarket, and on Kalshi, those three prices are rarely identical, and the gap between them is only tradeable if you can see all three at once.

That is the job Kairos does. One book across venues, sub-second data, and execution that lands before the spread closes. The venues keep multiplying. The terminal is what keeps them tradeable.
