Polymarket, predict.fun and Hyperliquid bets in one app

Prow Predictions is a prediction market aggregator. It puts the markets of Polymarket, predict.fun and Hyperliquid (its HIP-4 outcome markets) in one app: one feed, one bet ticket, one list of your bets. You see each outcome's chance on every venue that lists it, pick a side, and the bet goes from your own account on that venue. Prow never holds your money. One app helps because the same event often trades on two or three venues, with different prices, fees, rules and countries.

A share of the outcome that happens pays $1, and a share of any other outcome pays nothing. So a share's price is the market's chance: at 62¢, traders put the event at about 62%, and $100 buys about 161 shares that pay $161 if Yes wins.

What you can bet on

Each market is a question with outcomes, like who wins a game or an election, or where Bitcoin closes. On October 31, 2026, Prow's feed listed about 400 events from Polymarket, about 480 from predict.fun and 229 from Hyperliquid. Some events, such as NBA games and the Premier League winner, were on all three, so the counts do not add up. The live feed lists the most traded events now.

Hyperliquid calls its prediction markets outcome markets and defines them in HIP-4. An outcome is a fully collateralized Yes or No token: no leverage and no liquidation. Hyperliquid lists the daily Bitcoin, Ether, Solana and HYPE markets itself and settles them on its own price. Outside deployers such as outcome.xyz, Trade[XYZ] and Skew list the rest and settle their own markets alone, with no dispute window.

Polymarket vs predict.fun vs Hyperliquid compared

No venue is best for every bet. Facts are as of October 31, 2026; sources are under Sources.

Who settles matters most. On Polymarket and predict.fun the UMA oracle settles after the dispute window. On a Hyperliquid deployer market the deployer settles alone.

Same event, different prices

The same event often trades on more than one venue at different prices. Where Prow can match a market across venues, its event page shows each venue's chance and Yes and No price and marks the best price. It puts Polymarket odds next to predict.fun and Hyperliquid on one page. Fees can change which price is cheapest, so check the ticket's fee line.

The bet ticket sends your bet to one venue, chosen in this order:

1. The venue you picked on the event page, in the ticket's venue list or with a venue's own button.
2. Otherwise a venue where you already hold shares in that market, the larger position if you hold several.
3. Otherwise the cheapest venue, your connected venues first.

Steps 2 and 3 only look at the venues the feed's Venues filter leaves on, skipping a closed market and, where Prow can tell, a venue that refuses your country. The ticket's venue list lets you pick another venue and shows each one's price for your side.

Prow's Arbitrage tab lists pairs where the opposite sides of one event, bought on two venues, cost less than $1 together after every fee, keeping at least 0.5%. One side pays $1, so the gap is your profit if both venues settle the same way. Closest gaps lists pairs that nearly qualify. A gap can still lose money:

• The rules may differ. Venues can settle the same event differently, with other deadlines and sources. Prow shows both rules side by side and marks pairs that differ.
• One leg may not fill. Order books can be thin, and if only one side fills you hold a plain bet.
• Your money is locked until both markets settle, which can take days if one is disputed.
• You may not be able to hold both legs. Each venue is closed to some countries.

No gap is a sure profit.

How a bet works in Prow

1. Connect your accounts. Nothing shows as yours until you connect it. One Connect button does it in order. Prow creates a Polymarket or predict.fun account if you have none, and predict.fun needs a little BNB for approvals.
2. Pick a market and a side. Yes or No, or one of two teams. The ticket shows each side's price and what $1 turns into if it wins.
3. Enter the amount. Details shows the shares you get, the average price, the fees and the account the bet goes from, and how far a big bet moves the price.
4. Confirm. A market bet fills now at the best prices, never worse than the cap shown. A limit bet waits at your price until it fills or you cancel it.
5. Sell or hold. Sell before the market settles to take a profit or cut a loss. If you hold, winning shares turn into $1 each at settlement.

Your bets are under Predictions, then My bets. To start, open Predictions in Prow, or read the Prediction markets docs.

Your money stays in your accounts

Prow never holds your money. Every bet is placed from an account that belongs to you:

• Polymarket: a Polymarket wallet owned by your Prow wallet or by another wallet you pick. Your money stays in it.
• predict.fun: your own wallet on BNB Chain, which is your predict.fun account.
• Hyperliquid: your own account. Bets use the trading key on your device, which can place and cancel bets but cannot withdraw or move money. See How trading keys work and Hyperliquid agent wallets.

The Prow wallet is made for you by Privy when you sign in with email, Google, Apple or a passkey, and it is non-custodial: see Prow wallet. With it, bets and claims on Polymarket and predict.fun need no pop-up; anything else, such as sending money out, still asks you to confirm. With your own wallet, such as MetaMask, you confirm each of those bets in it.

What it costs

Prow's fee on a bet is 0% until the end of 2026, then 1% of the amount on Hyperliquid and Polymarket. Prow adds no fee of its own on predict.fun. After the free period a $100 bet carries a $1 Prow fee. On Hyperliquid it is a builder fee, which you approve once with your wallet. When the fee starts, the ticket asks for that approval before your next bet, and selling never waits for it. See Hyperliquid builder fees.

The venues' own fees, in the table above, come on top. The ticket shows every fee before you confirm.

Where it is available

Prow and each venue have their own country rules, all applied by where you are.

• Prow: not available to people in the US, UK, EU, UAE, Ontario (Canada), Cuba, Iran, North Korea, Syria, Russia, Belarus, and occupied regions of Ukraine.
• The venues: Polymarket is closed to many countries, predict.fun has its own list (in the docs), and Hyperliquid does not offer prediction markets to some accounts and countries. Prow checks before it shows a ticket or connects an account. Where Polymarket refuses, the ticket says Polymarket isn't available in your country and links to the market on polymarket.com. The link is for viewing only, not a way to bet.

Prow does not work around these rules, and its terms forbid using a VPN or proxy to get around its block.

Frequently asked questions

Is Prow a prediction market?

No. Prow is an app on top of three venues. Polymarket, predict.fun and Hyperliquid, with its deployers, make and settle the markets. Prow sets no odds, settles no outcome and holds no money.

Do I need a Polymarket account to use Prow?

No. If you have none, Prow creates one when you connect Polymarket, free and without pop-ups on a Prow wallet. predict.fun works the same way and also needs a little BNB.

Can I use Prow where Polymarket is blocked?

Not for Polymarket bets. Prow does not work around a venue's country rule, which applies by where you are: the ticket says Polymarket isn't available in your country and links to the market on polymarket.com, for viewing only. You can still use predict.fun or Hyperliquid if they take your country.

What does Prow charge?

0% until the end of 2026, then 1% of the amount on Hyperliquid and Polymarket bets, and no fee of its own on predict.fun. Each venue adds its own fee, and the ticket shows all fees before you confirm.

How do I collect winnings?

On Hyperliquid you do nothing: winning shares turn into USDC when the market settles. On Polymarket and predict.fun you claim from My bets once the result is final. On Polymarket that takes at least the 2-hour dispute window. A predict.fun claim is one BNB Chain transaction, paid in BNB.
