World Launches Solana Prediction Market in Phantom

The protocol runs non-custodially on Solana and uses Chainlink oracles for automatic payouts in CASH. Through Phantom, World gets direct access to millions of users, alongside Polymarket and Kalshi.

Key Takeaways

• World went live on July 1 as an onchain prediction market on Solana, built into Phantom Wallet.
• Settlement happens automatically through Chainlink oracles, and winning positions are paid out in CASH, a stablecoin on Solana.
• Phantom reaches about 20 million users and is replacing its earlier Kalshi integration with World for new positions.

World went live on July 1 as an onchain prediction market on Solana, now built directly into Phantom Wallet. Trades are settled automatically through Chainlink oracles using the CASH stablecoin, giving the Solana ecosystem a native competitor in a market currently dominated by Polymarket and Kalshi.

How World Works in Phantom

World is structured as a non-custodial protocol rather than a standard crypto exchange. Orders are sent to liquidity providers on Solana, while users keep their positions in their own wallet until they decide to exit. In other words, the platform does not take custody of customer funds or directly operate the markets.

Settlement is handled through Chainlink Data Streams and its runtime environment, which supply pricing data and help resolve outcomes largely on autopilot. Once a market is decided, winning positions are paid out automatically in CASH, a stablecoin on Solana. At launch, the available markets include simple up-or-down Bitcoin contracts, along with bets tied to the 2026 World Cup.

The timing is notable. Solana has been on a strong streak, and the SOL token climbed more than 5 percent on launch day and roughly 16 percent over the week, according to BeInCrypto data. The broader market for tokenized assets on Solana has also expanded in recent months, making the chain a more important venue for new onchain products such as prediction markets. That fits into a wider wave of activity on the network, from payments to tokenized assets; for example, MoneyGram is expanding its Solana push for stablecoin payments.

Phantom as a Distribution Channel

The launch also serves as the public debut of infrastructure that had already been live for weeks. Phantom had previously offered Kalshi markets through a DFlow integration since December 2025, but it moved new positions opened on or after June 1 over to World. Under the earlier setup, traders had to manually cash out winning positions; World now handles that step automatically after an event ends.

That shift matters because Phantom has around 20 million users. World now gets immediate distribution without requiring people to download a separate app. Even so, Kalshi remains a major rival, while Polymarket has already shown how much demand there can be for prediction markets.

What This Means for Europe

For European crypto readers, the main point is that prediction markets are increasingly being built straight into wallets instead of being offered as standalone platforms. That can make them easier to access, but it also highlights how different the market structures are, from regulated venues like Kalshi to permissionless protocols that operate without a license or gatekeeper.

Over the next few months, the key question will be whether wallet-based distribution and automatic onchain settlement are enough to keep liquidity deep. World has not shared its own volume or liquidity numbers yet, even though those order books are what ultimately determine how usable a market like this is.
