Phantom has shifted the infrastructure supporting prediction markets in its crypto wallet, replacing its previous Kalshi based system with World for positions opened from June 1.
The change moves new markets to a noncustodial protocol that routes orders to liquidity providers on Solana. Payouts are redeemed automatically when an event ends, removing the separate settlement trade required under Phantom’s earlier setup.
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. Older markets depend on Kalshi data processed through DFlow, while new positions may rely on oracles including Chainlink.
Phantom warned that delayed feeds, incorrect information or indexing failures could still affect market resolution and lead to financial losses.
The wallet said it does not take custody of user funds, operate as the counterparty to trades or maintain a house edge. Transactions take place between users, while each market follows its own resolution rules.
The updated disclosures also prohibit users from trading contracts when they possess material nonpublic information or have a direct conflict related to the outcome.
