World was launched on July 1 as an onchain prediction market on Solana (SOL), being a Phantom Wallet and using Chainlink oracles only to settle transactions in the CASH stablecoin.
Its launch adds Solana native challenger to the already leading Polymarket and Kalshi segment, where volumes have a solid track record.
How the World Works Inside the Phantom
The world works as an informal system rather than a traditional exchange. It makes calls to Solana funders and does not store user funds or run markets on its own. Traders keep positions in their wallets as tokens until they decide to invest.
The stability goes through Chainlink Data Streams and its fast environment, which feeds the trees and deals with the results with minimal human intervention. Winning positions automatically redeem CASH, the Solana stablecoin.
Pa to initiateWorld mentions short Bitcoin (BTC) up-or-down contracts and markets on 2026 FIFA World Cup. The start comes when Solana is running fast.
Solana’s SOL symbol it rose more than 5% per day and about 16% per week, according to BeInCrypto data.
The group plans to add sports, politics, and capital markets until July.
The World Has Changed Kalshi in Wallet
The launch is the public unveiling of a construction project that has been quietly underway for weeks. Phantom offered Kalshi-managed markets through the DFlow integration from December 2025. It then switched to World for all positions opened on or after June 1.
Under the previous setup, traders automatically redeemed the winning spots, while World automatically redeems them after the event.
The change is important because Phantom reaches almost 20 million users, and distributes it around the world without any other software. Kalshi, meanwhile, is still the main rival and is said to be weighing a A valuation of $40 billion.
Before its unveiling, the project ran a secret global campaign with the slogan “Trade Everything.” It also told its followers that “there is nothing.”
“Prediction markets are one of the most powerful applications that you can build on a high-end blockchain. The world is designed to showcase what Solana supports: real-time markets, onchain stability, and user experience that meets people where they are,” Pedro Miranda, Director of Consumer Affairs at the Solana Foundation, said in the launch announcement.

Can the World take Polymarket and Kalshi?
The incumbents carry moats The world has not been built. Polymarket confirmed the brand in 2024, when the revenue exceeds $3 billion to sell on his US presidential campaign. It has grown to Solana through the combination of February and Jupiter, competing with the turf World it says.
Their control methods vary greatly. Kalshi is a US regulated exchange that beats the CFTC in the court in 2024 to write election contracts. Polymarket took a different approach, paying $1.4 million CFTC price punishment in 2022 that forced the sea for many years.
The world leaves both sides, running as an unlicensed and unguarded onchain system.
That right cuts two ways. The unsecured version removes the middleman, and also eliminates the monitoring and security that imposes a controlled environment like Kalshi.
The country has not published figures for volume or revenue, so its trading strength remains uncertain. Prediction markets reward deep books, which produce narrower spreads and more stable prices. Distribution can attract users quickly, but this kind of depth takes time to build.
Part speed still helps, and predict the open market interest hitting a record of $1.48 billion in June.
Memecoin unrelated to the name of the World caused speculation on Pump.fun, although the group confirmed that there is no connection.
International law is based on distribution and immediate settlement, not confirmation. The World Cup will be the real test of whether getting inside the Phantom turns into a sustainable investment.
