Phantom Switches Prediction Market Infrastructure to World

Phantom, a leading crypto wallet, has revamped its infrastructure for prediction markets, replacing Kalshi with World for new positions opened from June 1. The changeover shifts new markets to a noncustodial protocol that routes orders to liquidity providers on Solana.

Payouts are now redeemed automatically when an event ends, eliminating the need for a separate settlement trade as seen in Phantom's earlier setup.

However, positions opened before June 1 remain tied to Kalshi through DFlow. Users holding those contracts must exchange expired outcome tokens for the stablecoin used to open the position, with the final quote potentially affected by market conditions and settlement data.

The transition also changes the external systems used to determine results, with older markets relying on Kalshi data processed through DFlow, while new positions may use oracles including Chainlink.
