Hyperliquid vs Polymarket vs Kalshi at a glance#

This table compares Hyperliquid's HIP-4 outcome markets with Polymarket and Kalshi as of 2 November 2026. Each fact is sourced in the section below it.

Regulation and who can trade#

Kalshi received its CFTC designation as a contract market in November 2020, under the entity KalshiEX LLC. In October 2025 Kalshi said it offers one global liquidity pool across 140+ countries. Check Kalshi's own list of excluded jurisdictions before you sign up.

Polymarket runs two products. Polymarket US is the regulated one: Polymarket bought QCEX, a CFTC-licensed exchange and clearinghouse, in July 2025 and received an amended order of designation in November 2025. The international site at polymarket.com is closed to US residents. Its geographic restrictions page, updated the week of 29 October 2026, blocks about 40 countries, including the United States, the United Kingdom, France and Germany, and puts several more on close-only.

Hyperliquid has no account sign-up at the protocol level: you connect a wallet. The Hyperliquid interface terms, last updated 15 June 2026, bar residents of the United States and Ontario and sanctioned jurisdictions, and let the operator block the outcome markets tab in further places. Section 1.3 states that neither the interface nor Hyperliquid is "licensed, approved, authorized, endorsed, or registered by any governmental authority". Other apps can reach Hyperliquid's markets, but each sets its own terms.

If regulatory protection or US access is your first filter, Kalshi and Polymarket US win, and Hyperliquid is not an option.

Custody and collateral#

Kalshi is a dollar account. You fund it by debit card, bank transfer, crypto or wire, among other methods, and Kalshi holds the balance. Polymarket US also takes dollars: debit card, ACH, Apple Pay, PayPal, Venmo, USDC or wire.

Polymarket's international platform is onchain. All trading collateral is pUSD, an ERC-20 on Polygon with 6 decimals, backed one to one by USDC with the backing enforced by its wrapping contracts. Orders are signed offchain, matched by an operator and settled onchain on Polygon.

Hyperliquid HIP-4 is onchain end to end. HyperCore keeps margin and matching engine state onchain and does not use offchain order books. HIP-4 markets quote in USDC, and every Yes and No pair is backed by one full USDC. You trade from a self-custody wallet, the same account that holds your Hyperliquid perps and spot. Hyperliquid's June 2026 portfolio margin announcement says accounts on portfolio margin can use BTC and HYPE as collateral across perps, spot and outcome markets. HyperCore vs HyperEVM explains where those balances live, and what Hyperliquid is covers the chain and its risks.

Self-custody cuts both ways. No company runs the account: transfers and withdrawals need your key's signature, orders need your key or an API wallet you approved, and nobody can recover a lost key or reverse a mistaken transfer for you. It is not control over everything, though. Circle's CCTP on HyperCore overview says USDC balances on HyperCore are protocol-level credits, with the native USDC held in Circle's CoreDepositWallet contract on HyperEVM, and liquidations close positions without your signature.

Fees: Hyperliquid vs Polymarket vs Kalshi#

On standard single markets, Kalshi and Polymarket charge a taker fee when an order fills, shaped so it peaks at a 50¢ price. Hyperliquid HIP-4 charges its protocol fee at the other end of the trade.

Kalshi. Kalshi's fees help page links its fee schedule, which sets the general taker fee at round up(0.07 × C × P × (1 - P)), where C is contracts and P the price in dollars. That is $1.75 on 100 contracts at 50¢. Some markets use different multipliers or charge makers, and Kalshi's schedule charges combo makers half the taker fee, except on uncorrelated NFL combos. Check the live schedule before you rely on these figures. Kalshi's API docs say settlement fees are zero for plain yes and no results.

Polymarket international. Polymarket's fee page uses fee = C × feeRate × p × (1 - p), charged to takers only, with these rates as of 2 November 2026:

Makers are never charged, and the fees fund maker rebates.

Polymarket US. The Polymarket US fee schedule, effective 19 October 2026, uses a standard taker coefficient Θ of 0.0695 ($1.74 on a 100-lot at 50¢), 0.10 for table tennis, and maker rebates for accounts with $10 million or more of monthly maker volume. Combos have their own taker curve, C × p × [0.0695 × (1 - p) + 0.085 × (1 - p)^4] from 28 October 2026, and combo fills earn no maker rebate. As of 2 November 2026 the page's combo examples still use the earlier 0.06 coefficient.

Hyperliquid HIP-4. Hyperliquid's fee schedule charges no protocol fee to open a HIP-4 position. Selling, settling and redeeming pairs pay a fee based on your account's spot fee tier, multiplied by scale + max(scale, 1) for the market's deployerFeeScale (0 to 10), with no maker rebates. Hyperliquid prints no flat outcome rate; its 14 August 2026 announcement said the average outcome fee would be half that of non-outcome spot, whose base taker rate is 0.070%. Over the 30 days to 2 November 2026, DefiLlama counts $103,420 of HIP-4 fees, builder fees included, on $79.5 million of volume. HIP-4 outcome markets has the full fee table and Hyperliquid fees puts it next to perps and spot.

Two practical consequences. On Kalshi and Polymarket, a trader who buys at 50¢ and holds to settlement pays the whole fee up front, and pays nothing more if the contract loses. On HIP-4 the same trader pays Hyperliquid nothing up front, pays on the payout if the contract wins, and pays Hyperliquid nothing if it loses and settles at zero. But apps can add their own charge: Hyperliquid builder codes let a frontend add a fee on HIP-4 buys and sells, so what you pay to open depends on the app you trade through.

Settlement and resolution#

Kalshi settles each contract at $1 or $0, and on some markets a scalar value. Kalshi itself determines the outcome from the source agency named in each market's rules, which can take from one hour to more than twelve after the market closes.

Polymarket resolves prediction markets through the UMA Optimistic Oracle. Anyone can propose a result by posting a bond, typically $750 in pUSD. A 2-hour challenge window follows, and a result disputed twice goes to a vote of UMA token holders. In the rare case the vote finds neither outcome applies, the market resolves 50-50 and each token redeems for $0.50. Up-down markets settle on a Chainlink TWAP instead.

Hyperliquid HIP-4 has three resolution paths. Recurring crypto price markets settle automatically to Hyperliquid's own mark price. Canonical markets on offchain events are deployed and settled by validator vote. Deployer markets settle when the deployer signs a settleOutcome action, with its 500,000 HYPE stake slashable by validators for a wrong or late settlement. The protocol gives traders no dispute window. Standalone HIP-4 markets can settle to any fraction, for example 0.66, which pays Yes holders 0.66 USDC and No holders 0.34.

Each model asks you to trust something different: a regulated company, a token-holder vote, or a staked deployer policed by validators. None is risk-free. Read the market's rules on all three; the title alone does not decide the payout.

Liquidity and volume#

Kalshi and Polymarket have far more volume than Hyperliquid HIP-4. DefiLlama's figures for the 30 days to 2 November 2026:

DefiLlama builds each venue's numbers from that venue's own data, so the methods are not identical. HIP-4 volume, for example, counts price times shares once per trade and leaves out splits, merges and settlements. The gap is still two orders of magnitude against Kalshi. Volume is not depth, though: these totals do not measure the spread or size on the market you want, so compare the books on that market before you trade. A tight spread on a deep book saves more than any fee difference.

Combos and parlays on each venue#

A combo, also called a parlay, joins several outcomes into one position. When every leg settles plain Yes or No, it pays only if every leg wins; legs that settle at a fraction change that, as below.

Kalshi Combos are priced by request for quote, become their own market with their own order book, and pay the product of the underlying results, so a leg that settles at a fair value instead of $1 scales the payout. Kalshi lists them across sports, entertainment and more. Polymarket's Combos are also RFQ-priced and, as of 2 November 2026, cover sports markets only: moneyline, spread and total.

Hyperliquid has no native combo. Apps build them on top of HIP-4. Totalis, which publishes this comparison, is one: in the Totalis app, a Combo joins 2 to 5 HIP-4 outcomes into one position with one payout, quoted by market makers through an RFQ and held in a HyperEVM vault until Hyperliquid's results settle it. A Combo pays its payout times the product of its legs' HIP-4 results, so a leg that settles at a fraction scales the payout, much like a Kalshi combo. Not every HIP-4 market takes Combo positions. Totalis charges 1.5% of stake on entry and 1% of proceeds above the net stake, listed with every limit on the Totalis Combo fees and limits page; how a Combo settles walks through each settlement state.

For the pricing and correlation math behind multi-leg positions, see how prediction market parlays work. If the words are new, combos and parlays are the same trade.

When Polymarket or Kalshi is the better choice#

Pick Kalshi or Polymarket, not Hyperliquid, when:

• You are in the United States. Kalshi and Polymarket US are open to US residents under CFTC oversight. Hyperliquid's interface is not.
• You want regulatory protection. A designated contract market answers to the CFTC. Hyperliquid's terms disclaim any licence.
• You need liquidity. On DefiLlama's 30-day figures to 2 November 2026, Kalshi trades about 200 times HIP-4's volume. More trading usually means more resting orders, but check the spread and size on your own market.
• You want the widest market list. Kalshi and Polymarket list far more events, across politics, geopolitics, culture and weather. HIP-4 markets come from a short list of validator-approved templates.
• You want to fund with a card or bank. Kalshi and Polymarket US take dollars directly. HIP-4 needs USDC on Hyperliquid.
• You want a dispute path. Polymarket has a 2-hour challenge window and a token-holder vote; Kalshi resolves under regulated rules. HIP-4 deployer markets have no trader dispute step.

Where Hyperliquid HIP-4 differs#

Hyperliquid's prediction markets are worth a look when these trade-offs suit you:

• Onchain order book. Every order, match and settlement is chain state on HyperCore, with no offchain matching operator.
• Self-custody. You trade from your own wallet, and only keys you authorize sign orders for your account.
• One account with perps. HIP-4 sits in the same Hyperliquid account as perps and spot, and portfolio margin covers outcome markets too.
• No protocol fee to open. Hyperliquid's fee comes when you close or settle, and a losing position that settles at zero pays none. An app's builder fee can still apply when you buy.
• Fractional settlement as a general tool. Any standalone HIP-4 market can settle to any value from 0 to 1, which makes scalar markets possible. Scalar markets on HIP-4 explains the payoff.
• Permissionless deployment. Since a late-August 2026 upgrade, confirmed in Hyperliquid's 31 August update, any team that stakes 500,000 HYPE can list markets from approved templates, the same model HIP-3 builder-deployed perpetuals uses for perps.
• Composability. HyperEVM contracts can read HIP-4 results and send outcome operations through CoreWriter, which is how apps build products such as Combos on top.

Frequently asked questions#

Is Hyperliquid cheaper than Polymarket?#

It depends on the trade and the app. Hyperliquid HIP-4 charges no protocol fee to open and takes its fee on close or settlement, with no protocol fee on a position that settles at zero; the app you trade through may add a builder fee. Polymarket charges takers on entry, from 0.04 to 0.07 times p × (1 - p) per share, nothing on geopolitics, and never charges makers. Over the 30 days to 2 November 2026, HIP-4's fees on DefiLlama were about 0.13% of its volume, but its books are much thinner, and spreads often cost more than fees.
