The settlement record.
Every weekly market, how it settled, and what the house made or lost. Nothing here is typed in by hand: each number is read from the contracts on Base Sepolia when you load the page.
Read live from Base Sepolia. Testnet, unaudited. Every figure is checkable on Basescan.
Weekly markets
Amounts are tUSDC on a testnet and have no cash value. Volume is fee-exclusive LMSR notional, counting buys and sells. If the price settles outside a market's grid, the nearest edge bucket wins and the row is flagged. Click a market name to open its contract on Basescan.
Reading the house P&L column
The market maker is an LMSR. Its worst-case loss is fixed at b · ln n and paid in as the subsidy when a market is created. That is the number after the slash. House P&L is what the market maker is currently up or down against that bound, including fees collected.
A negative number is normal and is the subsidy doing its job: it means traders, on balance, forecast the week better than the starting curve did. It can never go below the bound. We show it rather than hide it because a venue that only shows its wins is not one you can size against.
Verify it yourself
Settlement is permissionless and runs off the Chainlink BTC/USD feed. It pins the first round after close and takes the time-weighted average of the final two hours. No one at VibeKast chooses the outcome.
