Phantom’s Onchain Prediction Markets Reportedly Use World.xyz

World.xyz has been identified as the infrastructure powering prediction markets inside the Phantom wallet, with orders settling fully onchain and non-custodially on Solana using Chainlink oracles, according to a post from account @0xRyze on X. The disclosure reframes what looked like a standalone feature inside Phantom as a Solana-native protocol running underneath the wallet’s interface rather than a separate app users had to seek out.

World.xyz Infrastructure Behind Phantom Prediction Markets

The core claim, per the sourced post, is straightforward: World.xyz deploys the settlement layer, Phantom provides the order-routing front end, and the two together let users open prediction-market positions without ever leaving their wallet. Settlement runs through Solana with Chainlink oracles and Data Streams handling price and outcome resolution, which is the mechanical detail that separates this from a custodial betting product – positions and payouts are said to move through onchain rails rather than an internal ledger controlled by Phantom or World.

According to the same disclosure, positions opened after June 1, 2026 route through World, with CASH named as the stablecoin used for non-custodial execution. The market categories cited include crypto, the 2026 FIFA World Cup, general sports, and macro events – a spread that mirrors the kind of retail-friendly event contracts that have driven prediction-market volume elsewhere in the industry.

What’s notably absent from the available evidence is a formal statement from Phantom or World.xyz itself, an executive quote, or documentation confirming the full mechanics of custody and settlement beyond what the sourced post describes. Readers should treat the June 1 routing date and the CASH settlement detail as reported facts from a single account rather than confirmed disclosures until Phantom or World.xyz publish their own materials. For context on how Phantom has handled network support changes in the past, see Phantom’s decision to end Sui support, and for the performance layer underneath this integration, Solana’s move to 350ms slot times is directly relevant to how quickly onchain prediction markets can resolve.

Where This Sits in Phantom’s Broader Trading Push

Separate reporting – not confirmed in the primary disclosure reviewed here – suggests Phantom’s prediction-market feature originally launched in partnership with Kalshi, giving wallet users access to CFTC-regulated event contracts alongside whatever World.xyz is now said to power. If accurate, that would mean Phantom is running two parallel prediction rails: a regulated exchange-backed one through Kalshi and a permissionless, fully onchain one through World.xyz. That distinction matters for risk profile – regulated contracts carry different custody and dispute mechanics than onchain, oracle-settled ones – but it has not been independently verified for this article and should be read as reported context rather than fact.

Similarly unverified but worth flagging: reports describing Phantom’s user base at roughly 20 million and CASH as a Stripe-issued stablecoin already used across swaps and other trading features. If those figures hold up, World.xyz’s integration would represent access to a meaningfully large existing wallet audience rather than a cold-start launch, which changes the calculus for how quickly onchain prediction-market volume could scale on Solana. Traders should also note that a separate WORLD token already circulates on Solana DEXs under the same name; nothing in the available evidence establishes a confirmed link between that token and the World.xyz protocol, and no protocol token has been announced as of this writing.

The broader signal, if the reported details prove accurate, is that Solana’s retail trading stack is consolidating multiple products – swaps, perps, tokenized equities, and now prediction markets – inside a single wallet UX rather than spreading them across separate dApps. That consolidation trend is worth watching alongside network-level developments like the recent Solana disinflation vote, which shapes the token economics underpinning all of this activity.

What Comes Next

Reported plans – again unconfirmed by primary source material – point toward World.xyz expanding its market catalog into geopolitics and broader macroeconomic events, and toward more complex contract structures beyond simple binary yes/no outcomes. If Phantom continues layering derivatives-style products into its interface the way it reportedly has with perps and tokenized stocks, prediction markets look like the next piece of a wallet that’s positioning itself as a one-stop retail trading hub on Solana rather than a pure custody tool.

For now, the confirmed piece is narrower than the narrative around it: World.xyz is described as the onchain settlement infrastructure behind Phantom’s prediction markets, using Solana and Chainlink to route and resolve trades non-custodially, with CASH as the settlement currency. Everything about user scale, prior partnerships, and future roadmap remains reported context that traders should verify against official Phantom or World.xyz statements before sizing any position around it.
