Every day, new head-to-head matchups go live on Barz. Two artists, one question: who charts higher on Spotify US Daily tomorrow?Each market has two outcomes. You buy shares in the outcome you believe in.
Barz uses an automated market maker (AMM) with a bonding curve. Share prices start near $0.50/$0.50 and shift based on demand.If more people buy one side, that side gets more expensive and the other side gets cheaper. The price of a share reflects the crowd’s implied probability of that outcome winning.If you see a share at $0.35, the market is saying that outcome has a 35% chance of winning. If you think it’s higher than that, you’ve found an edge.
When the market closes, the oracle pulls verified streaming data from Kworb, which tracks official Spotify chart positions and stream counts.The resolution process stores evidence on IPFS, creating a permanent, verifiable record of the result. The winning outcome is written on-chain. No human judgment involved.
If you held shares in the winning outcome, head to your portfolio and claim your USDC payout. Payouts are calculated proportionally from the market’s vault — all funds deposited by both sides, minus the 2% fee.If you held the losing side, your shares expire worthless.
