FAQ

What is Spend Market?

A prediction market that resolves on verified U.S. consumer transaction data. You take positions on what American consumers will do; real purchase data decides the outcome.

What network does it run on?

Arbitrum. All positions are denominated in USDC.

Do I need to know anything about crypto?

No. Sign in with email or social and a non-custodial wallet is provisioned for you. If you already have a wallet, connect that instead.

How do I earn promo credit?

Two ways, and they stack: $5 for connecting a bank, and $5 per friend you refer who deposits and trades $5 or more. See Ways to Earn.

Is promo credit real money?

Promo is display credit you trade with, not cash. You can't transfer or withdraw it directly. But anything you win trading with it is real, and real winnings are yours to withdraw anytime.

How does the referral program work?

Share your invite code. When a friend signs up with it and deposits $5 or more in USDC, you both get $5 in promo credit. Deposits are cumulative and there's no time limit.

Is there a limit on referral rewards?

Promo from referrals is capped at $500 per person lifetime. After that you can keep referring, but no further promo is awarded.

Does my friend have to deposit for me to earn?

Yes. The referral stays pending until they deposit $5 or more. No deposit, no reward, but it can convert anytime later.

Can I use my own code, or use more than one?

No self-referrals, and a friend is locked to the first code they use at signup. Codes apply only during signup, never retroactively.

Do referral codes expire?

No. Your code doesn't expire and can be shared with unlimited people.

Do I need to connect a bank account?

No. It's optional. Connect one and we'll add $5 in promo credit. It's a separate program from referrals.

How do I fund my account?

If you've earned promo credit, you can trade with it first. When you're ready to add more, send USDC to your Spend address on Arbitrum, or buy USDC directly in the app through Privy. See Funding Your Account.

What determines a market's price?

In Phase 1 (Early Pool), the ratio of capital across outcomes. In Phase 2 (Open Market), whatever trades clear at. Either way, prices sum to ~$1.00.

Can I sell before a market resolves?

In Phase 2, yes. In Phase 1, no. Your collateral is locked until resolution or graduation.

Do all markets graduate?

No. Markets that don't hit the threshold resolve from Phase 1. By design.

What's a complete set?

One of every outcome token, redeemable for $1.00. It keeps the order book's prices summing to ~$1.00. See Graduation & Complete Sets.

How is the outcome determined?

Through Revere, Spend Market's oracle, against the rules on the market page. See Data & Revere.

How long does resolution take?

48 hours after close.

What happens if a market is tied?

All positions refund in full.

What are the fees?

A Phase 1 tiered entry fee, a Phase 2 maker rebate / taker fee, and a 1% net-profit fee on winnings. All shown up front. See Fees.

Does Spend hold my funds?

No. Spend Market is non-custodial; your funds stay in your wallet.

What do you see when I connect my bank?

Anonymized transaction records and balances, never your login or identity. See Privacy & Data Handling.

Can I disconnect my bank later?

Yes, anytime. If you'd already earned a referral reward, disconnecting later doesn't reverse it.

Can I delete my data?

Yes. Email [e-mail].

My deposit didn't arrive.

Confirm the network is Arbitrum and that you sent USDC. If it still hasn't landed after network confirmations, email [e-mail].

I lost access to my embedded wallet.
