The first prediction market on Mezo

Call it right. Keep your bitcoin.

Borrow MUSD against your BTC on Mezo, back Yes or No, and get paid in MUSD when you're right.

Browse markets How funding works
No38¢
Yes62¢
Tap the square to move the line. However you split it, a Yes and a No add up to exactly 1 MUSD.

Your bitcoin stays yours.

You don't have to sell BTC to place a trade. Borrow MUSD against it on Mezo and trade with that, or use the MUSD you already have.

You hold BTC

Example trade

  1. 1Borrow MUSD on Mezo

    Lock BTC as collateral and borrow MUSD, Mezo's bitcoin-backed dollar. How much you can borrow depends on the BTC price and Mezo's limits.

    You receiveMUSD to trade with

  2. 2Buy Yes or No here

    Say you put 1,000 MUSD on Yes at 40¢. A share costs 1¢ to 99¢ and pays 1 MUSD if you're right.

  3. 3Collect, then repay

    If Yes wins you're paid in MUSD. Repay the loan on Mezo when you choose, and your BTC unlocks.

Loans live on Mezo, with Mezo's fees, interest and liquidation rules. MEZONK never holds or lends your bitcoin.

Got MUSD you're not trading with?

It works across Mezo too. A few things you can do with it on Mezo mainnet:

  • Save it

    Deposit into Mezo's MUSD Savings Vault. It earns a variable rate from MUSD loan fees, with no lock-up.

    Savings Vault

  • Swap or add liquidity

    Trade MUSD for BTC, USDC or USDT on Mezo Swap, or add it to a pool and earn a share of swap fees.

    Mezo Pools

  • Pay down your loan

    Borrowed MUSD on Mezo? Paying some back lowers your debt and your liquidation risk. There's no fixed repayment date.

  • Pick up a veNFT

    Vezo is a marketplace for veBTC and veMEZO positions that accepts MUSD. Listings come and go.

    A community project by the team behind MEZONK, not run by Mezo.

  • Move it to Ethereum or Base

    Bridge MUSD with Wormhole if you need it on another chain.

All markets

The first markets on Mezo are on their way.

Trading isn't switched on for this network yet. Suggestions are already open and reviewed in public.

From question to payout.

Every market goes through the same four stages, in the open, on Mezo.

  1. 1Backers fund both sides

    A reviewed market opens for seeding. Backers lock real offers on Yes and No. If both sides aren't funded by the deadline, everyone gets their deposit back.

    Will BTC close above $150,000 on 31 December?

    4 backers · goes live when both sides are funded, refunds if not.

  2. 2Anyone can trade

    Once both sides are funded the market goes live. Buy Yes or No from other people's offers, sell any time before close. MEZONK never takes a side.

  3. 3The outcome is checked in public

    After close, the resolver proposes Yes, No or Invalid with evidence and a bond. Anyone can challenge it during the window; an arbitrator rules.

  4. 4Winners are paid in full

    Each winning share redeems for exactly 1 MUSD, straight from the contract. If a market is ruled Invalid, every share pays 0.50.

Don't trust us. Check.

Bitcoin people verify. Everything that decides who gets paid lives on Mezo, readable by anyone.

Read the contracts
The rules can't move
Every market's rules are fingerprinted on-chain the moment it opens. Each market page checks the fingerprint still matches, so nobody can quietly edit the question.
You can argue with the result
Every outcome comes with evidence and a challenge window. Think it's wrong? Post a bond and say so; an arbitrator rules in public.
Nothing gets stuck
If nobody proposes an outcome, or a ruling runs late, the market settles Invalid and every share pays 0.50 MUSD.
Your claim is yours
Even if trading is paused, claims, refunds and resolution keep working. The money sits in the contract, not with us.

Know something the market doesn't?

Suggest the question. Write rules a stranger could check, a curator reviews them in public, and backers decide if it goes live.
