How it works

A prediction market is a marketplace for buying and selling shares in the outcome of a future event. Each market on HighGardenresolves to either YES or NO based on a publicly defined source of truth. Share prices reflect the market's collective estimate of the probability of the event occurring.

A YES share priced at $0.62 means the market is implying a 62% probability of YES. If the event resolves YES, every YES share pays out $1.00. If it resolves NO, YES shares pay $0.00 and NO shares pay $1.00.

Browse markets across politics, crypto, sports, geopolitics, culture, tech, and more. Every market has a public rule set that defines exactly what triggers a YES vs. NO resolution and the source used to determine the outcome.

Read the rules in full before placing a trade. Once a market is live, the rules cannot be changed.

The order book shows the current bid and ask for YES and NO shares. Enter the side and size you want and HighGarden will quote a fill price based on available liquidity. Larger orders may fill across multiple price levels.

Trades settle in USDC on Solana. The Solana network fee (gas) is paid in SOL by the wallet signing the transaction.

Connect a Solana wallet, approve the transaction, and the position is recorded on-chain. HighGarden is non-custodial — your USDC is held by the market contract, not by us, and the position is owned by the wallet that signed the trade.

You can exit the position any time before the market closes by selling your shares back into the order book at the prevailing price.

Prices move as new traders enter, news breaks, or the underlying event unfolds. The price chart shows the implied probability over the lifetime of the market. Volume, open interest, and recent trades are all visible from the market page.

When the source of truth confirms the outcome, the market resolves on-chain. Winning shares become redeemable for $1.00 each in USDC; losing shares are worth $0.00.

For the rare cases where the source of truth is unavailable, ambiguous, or compromised, HighGarden applies a documented fallback procedure that can include market invalidation and a pro-rata refund of stake.

Once a market is resolved, winning positions are claimable from the portfolio page. Sign the claim transaction and the USDC is sent directly to your wallet. There is no holding period and no off-chain settlement layer.

HighGarden charges a protocol fee on filled orders and on settlement payouts. The current fee schedule is published on the trading interface and applies uniformly to all participants. Solana network fees (gas) are paid in SOL at transaction time.
