World Launches Solana-Based Prediction Market Inside Phantom Wallet to Challenge Polymarket and Kalshi

The prediction market industry has a new competitor. World, a fully on-chain prediction market protocol built on Solana, has officially launched inside the Phantom wallet, giving millions of users direct access to decentralized event trading without leaving one of crypto’s most popular self-custody wallets. Powered by Chainlink oracles and settled entirely on-chain, World is positioning itself as a next-generation alternative to industry leaders Polymarket and Kalshi by combining instant settlement, self-custody, and seamless wallet integration.

Unlike many prediction market platforms that require users to create separate accounts or deposit funds into custodial services, World allows users to participate directly from the Phantom wallet while maintaining control of their assets. The launch represents another major milestone for the rapidly growing prediction market sector, which has become one of the fastest-expanding segments of Web3 over the past year.

Prediction Markets Come Directly to Phantom

World is now integrated directly into the Phantom wallet, one of the largest self-custody wallets in the Solana ecosystem.

Rather than operating as a standalone application, the protocol allows users to access prediction markets from within the wallet interface, lowering the barrier to entry for millions of existing crypto users. All positions remain non-custodial, with users maintaining ownership of their assets throughout the trading process.

By launching inside Phantom, World gains immediate exposure to one of the largest consumer audiences in Web3, eliminating many of the onboarding challenges that have historically limited adoption of decentralized prediction markets.

Built Entirely On-Chain Using Solana

World has been designed as a fully on-chain prediction market protocol.

Every trade, market position, and settlement occurs directly on the Solana blockchain without relying on centralized custody or off-chain settlement systems. Winning positions are automatically redeemed when markets conclude, creating a smoother user experience than earlier prediction market models that often required manual settlement.

The platform currently settles transactions using the CASH stablecoin while leveraging Solana’s high-speed, low-cost infrastructure to process trades efficiently.

Chainlink Powers Market Resolution

To ensure accurate market outcomes, World has integrated Chainlink as its primary oracle provider.

Chainlink’s decentralized oracle infrastructure supplies real-world data used to automatically resolve prediction markets and distribute payouts once events conclude. This eliminates much of the manual intervention traditionally associated with prediction market settlement while improving transparency and reducing settlement delays.

Reliable oracle infrastructure has become increasingly important as prediction markets expand into financial assets, sports, politics, and global events where accurate data is critical to maintaining user trust.

Bitcoin and FIFA World Cup Markets Launch First

World’s initial release focuses on two high-interest categories.

Users can immediately begin trading markets tied to:

• Bitcoin price movements
• 2026 FIFA World Cup outcomes

The company says additional markets covering politics, macroeconomics, cultural events, and other real-world topics are expected to roll out in the coming months as the platform expands.

The strategy mirrors the broader evolution of prediction markets, which have grown well beyond election forecasting into financial, entertainment, and sporting events.

A Direct Challenge to Polymarket and Kalshi

World enters one of crypto’s fastest-growing sectors at a time when prediction markets are attracting unprecedented attention.

Polymarket has emerged as the leading decentralized prediction market, while Kalshi continues expanding its regulated event contracts within the United States. World aims to differentiate itself through full on-chain settlement, seamless wallet integration, automatic payouts, and the scalability of the Solana network.

Its direct integration with Phantom also provides a significant distribution advantage by placing prediction markets inside a wallet already used by millions of crypto participants.

Prediction Markets Continue Going Mainstream

The launch reflects the rapid maturation of blockchain-based forecasting platforms.

Prediction markets are increasingly being used to estimate the probability of elections, sporting events, cryptocy prices, economic data releases, and geopolitical developments. Many analysts view these markets as valuable information aggregation tools because they combine financial incentives with collective forecasting.

As blockchain infrastructure continues improving, prediction markets are becoming more accessible to everyday users through familiar wallets and consumer applications rather than specialized trading platforms.
