On September 9, about 5 hours after World.xyz's official launch post publicly opened the trading portal, the website crashed due to too many users flooding in; the official team announced a temporary shutdown and then announced restoration 29.5 hours later.

Taking advantage of the just-restored window, this editor tried it out and is sharing the experience.

No deposits or withdrawals needed, trading experience is silky smooth

This should be one of World's biggest selling points as "yet another prediction market": after connecting a Solana wallet, there is no need to first transfer funds into World's separate trading account. When trading, you only sign an on-chain transaction.

If the wallet holds SOL or USDC, the system will handle the conversion into the assets needed for settlement within the transaction. Users do not need to open another account just to participate in the market.

For many users with fund security needs, skipping the deposit step not only makes interaction more convenient, but also adds a layer of confidence in control over funds. Combined with Solana's on-chain settlement speed, the overall buying and selling experience is very smooth, with almost 0 delay.

The real problem is not at the level of interaction smoothness.

No limit orders, betting against the house

Unlike the CLOB mechanism used by competitors such as Polymarket and Kalshi, World has no order book and does not support placing limit orders.

Independent research by Chainstack Labs identified two main opposing market makers for users: JanusFI and BisonFI. The research labeled the former as a market-making program highly associated with World, and the latter as an independent third party; World has not yet publicly disclosed the full market-maker relationships and quoting rules.

This editor selected "up" in the "Will Bitcoin rise or fall overall this hour" market, entered a specific amount, accepted the quoted odds, and submitted the wallet signature; the market maker then took the "up" side back from this editor and kept the "down" side for itself.

Simply put, this editor must first accept the quote given by the market maker before the match can occur. This also means that, in terms of experience, users are more like accepting the house's current price: they cannot see the prices at which other people are willing to buy or sell, nor can they post a price themselves and wait for a match.

Another noteworthy point is the two-sided spread. For example, in the "Fed rate cut before 2027" market, the buy price for "Yes" is 11c and for "No" is 92c, and the two sides add up to 103c.

This is not the bid-ask spread for the same asset in a traditional CLOB, but rather the complete set purchase gap: simultaneously buying a set of "Yes" and "No" requires paying 103c, but regardless of the outcome, this complete set ultimately corresponds to only $1.

In the same "Fed rate cut before 2027" market, this premium is 1c and 0.1c on Polymarket and Kalshi, respectively.

Although this 3c cannot be directly equated with "the platform charging a 3c fee"—it could come from market-making spreads, routing costs, or inventory risk—the platform has not specified who exactly collects this 3c or what service it corresponds to.

Chainstack Labs deconstructed an actual trade sample, converting based on the CASH paid by the user, the other-side tokens left with the market maker, and additional payment paths, ultimately producing a premium of approximately 2.16%. Although this is not a unified fee schedule published by World, it at least demonstrates that costs can indeed be folded into quotes and fund flows that users cannot see.

In World's current market categories, themes such as crypto, sports, and politics are spread broadly. Changing the amount from $100 to $1 billion results in almost no change in the odds displayed on the page; how odds change with the amount invested in real trading scenarios and how high slippage is—the platform currently does not provide detailed explanations.

Ambiguous Settlement Rules

For short-cycle up/down markets, World's settlement rules are relatively clear: the time window, price target, and data sources are all fairly well-defined, and the platform officially uses Chainlink as its primary oracle infrastructure.

However, World has also listed a large number of events that require natural language interpretation, such as "GameStop will acquire eBay in 2026." Such rules specify: a binding final agreement must be publicly announced before a certain date; letters of intent do not count; the acquisition transaction itself does not necessarily need to be completed.

It appears to have been written in great detail, but the real disputes often arise in edge cases.

Suppose GameStop issues a statement saying it will acquire a certain sub-business of eBay at 8AM Beijing time on January 1, 2027.

Since 8AM Beijing time on January 1, 2027 still falls within 2026 in U.S. Eastern Time, the time zone not specified in the rules becomes a potential dispute risk; likewise, whether a "sub-business" meets the "acquisition" conditions in the rules is another layer of dispute that could affect the settlement direction.

These are not nitpicking; they directly affect how users price the current probability of that market.

World's public terms leave the choice of oracle and settlement process to the market creator; the foundation also does not take on the role of arbitration or overriding rulings. This does not mean no one will settle it, but rather that before buying, users find it hard to know: in the event of an edge-case dispute, who interprets the rules, which information source takes priority, whether there is a challenge window, and who ultimately decides whether the matter should settle as "Yes" or "No."

World has already made "on-chain prediction markets" very lightweight: fund security and a smooth trading experience. But the fair mechanisms that can ensure user retention, fee transparency, and dispute settlement methods still remain to be examined.
