A MARKET SANDBOX

Real questions.
Simulated conviction.

  1. Explore open markets. Discover the top 30 usable Yes/No markets by 24-hour volume.
  2. Choose a side. Buy Yes or No shares with virtual funds. A price of 40¢ implies a 40% market probability, not a guarantee.
  3. Practice a trade. Buys use the current ask; sells use the bid. Fills are immediate and capped at displayed top-of-book depth. No slippage, real fees, or market impact are modeled.
  4. Track your perspective. Average-cost basis, realized P&L and bid-marked unrealized P&L stay in your browser. Missing/stale marks show as unavailable.

Quotes expire after 30 seconds. Historical snapshot mode is browse-only. No payouts or settlement are simulated; no winners are invented. Export your ledger before clearing browser data.
