PredictionSwap Overview
PredictionSwap is a prediction market aggregator. It pulls live odds from Kalshi, Polymarket and Limitless into one feed, so you can compare the price of the same event without opening three tabs. The pitch is best odds on prediction markets, and the comparison part holds up: a Kalshi market page shows the chance of Yes, total volume, 24 hour volume, open interest, a price chart, bid, ask, spread, and a link to the same question on Polymarket.
It suits traders who already move between venues. Kalshi trades don't happen inside the app, the trade button opens Kalshi in a new tab. Polymarket and Limitless markets trade on the site with a connected wallet. Browsing is free, with no subscription.
The other half of the product is its own market set on Robinhood Chain. You buy Yes or No in USDG on a stock or crypto price, or on the market cap a token reaches, and a winning share pays $1. Price markets settle themselves off a Chainlink feed. Market cap markets go to a resolver. Anyone can open a market by seeding its pool with USDG, and that market's creator and liquidity providers take 75% of every trading fee, which works out to 1.5% of volume.
Every buy and sell pays 2%. A quarter of that fee buys $PSWAP on Uniswap v4 and burns it in one transaction, with no treasury cut. There is also Expiration Sniper, built for markets about to close: if a market prices something at 90% and you think it settles at 100%, you take the last 10%. No fees on that one.
What separates PredictionSwap from a plain odds board is the AI layer. The site says a private news index and vector database rank edges, flag mispricings and write a short rationale for the trade. That is the claim I would want to test in person before leaning on it.
Where it stands today matters if you plan to use it. The Kalshi and Limitless feeds load live prices and work as a comparison tool. The native markets on Robinhood Chain have all expired, and liquidity on them ran to tens of dollars a market. Use it to shop odds first and to trade second.
Note: activity has slowed since late September 2026, and its own Robinhood Chain markets have all expired; check the official channels before trading.
PredictionSwap Key features
-
Cross-venue odds feed
PredictionSwap pulls live odds from Kalshi, Polymarket and Limitless into one feed. You can compare prices on the same question without opening three tabs.
-
Kalshi market pages
Each Kalshi market shows the chance of Yes, volume, open interest, a price chart and the bid/ask spread. A lookup button finds the same question on Polymarket.
-
In-app Polymarket trading
Polymarket and Limitless markets trade inside PredictionSwap once you connect a wallet. Kalshi trades open on Kalshi in a new tab.
-
Expiration Sniper
A tool for trading markets just before they close, pitched as capturing the last few percent when the outcome is already clear. It launched with zero fees, though the page often failed to load during checks.
-
Native Robinhood Chain markets
Users buy Yes or No in USDG on where a stock or crypto price will land, or on the market cap a token reaches. Winning shares redeem for $1.
-
Create your own market
Anyone can open a market by seeding its pool with USDG. Creators and liquidity providers take 75% of every trading fee on that market.
-
Chainlink price settlement
Stock and crypto price markets settle themselves from Chainlink feeds. If a feed stops working, the market can be voided and every share redeems for 0.5 USDG.
-
Fee split and burn
Every buy and sell pays a 2% fee on collateral. Three quarters go to the market's liquidity providers, and the rest buys $PSWAP on Uniswap v4 and burns it.
-
AI market analysis
The team says AI ranks edges, flags mispricings and explains the trade in seconds. That layer is hard to find as a separate feature on the live site.
-
Non-custodial wallets
Every trade is signed from your own wallet. The terms say PredictionSwap cannot hold funds, change reserves or change an outcome.
PredictionSwap Fees
-
Trading fee Every buy and sell on PredictionSwap's own Robinhood Chain markets charges a 2% fee on the collateral, which is USDG.
-
LP cut 75% of that fee goes straight to the market's liquidity providers, which the team describes as LPs earning 1.5% of all volume.
-
Buyback and burn The remaining 25% accrues as a protocol fee, and the team uses it to buy $PSWAP on Uniswap v4 and burn it, with no treasury cut.
-
No-fee actions Splitting or merging complete sets, adding or removing liquidity, and redeeming shares cost nothing, though Robinhood Chain gas is paid in ETH.
-
Aggregator access Browsing the Kalshi, Polymarket and Limitless feeds is free, and the site lists no subscription or paid plan.

How to use PredictionSwap
-
Open the web app
Load the PredictionSwap site in a browser. There is no app store listing, so the web app is the only way in.
-
Choose a venue feed
Use the top navigation to open Kalshi Markets, Polymarket Markets or Limitless Markets. Each feed lists odds and volume for that venue.
-
Compare the same market
On a Kalshi market page, scroll to the 'Same question on Polymarket' lookup. It shows what the other venue charges for the same outcome.
-
Read the market details
Check chance of Yes, 24h volume, open interest, bid, ask and spread before you commit. The price chart runs from 1H to ALL.
-
Trade Kalshi externally
Press 'Trade on Kalshi' and the market opens on Kalshi in a new tab. PredictionSwap does not execute Kalshi trades for you.
-
Connect your wallet
Link a wallet to trade Polymarket and Limitless markets inside PredictionSwap. Every trade is signed from your own wallet, so the site never holds your funds.
-
Try Expiration Sniper
The homepage button targets markets close to expiry, with zero fees. During checks the page often timed out, so treat it as unreliable.
-
Create a market
Open the Create a market page and pick a stock or crypto price market or a token market cap target. Seed the pool with USDG to open it.
-
Provide liquidity
Add USDG to a market pool and you take 75% of the 2% trading fee. You also carry the outcome risk if traders lean the other way.
-
Redeem your shares
Winning shares pay 1 USDG each after settlement. If a Chainlink feed fails and the market is voided, every share redeems for 0.5 USDG.
-
Check the burn page
The page shows $PSWAP bought on Uniswap v4 and destroyed. The last burns ran about 52 days before the check date, so do not expect daily action.

Worth remembering $PSWAP already went through a rough first chapter on Believe launchpad. A lot of based devs got burned by that unsupportive founder, and it easily could've killed the project. Instead, they kept building. That's probably the part I respect most.

Prediction markets are a hot narrative right now and $PSWAP @PredictionSwap has been building for more than 3 months A prediction market aggregator that's catching attention Following my quant @supercontraa We caught #Actions early and $Pswap will be no different.

Pros
- It shows Kalshi, Polymarket and Limitless odds in one feed, and browsing costs nothing.
- Kalshi market pages list the bid, ask, spread, open interest and a price chart without a login.
- A "Same question on Polymarket" link on Kalshi pages makes price comparison quick.
- Anyone can open a market by seeding its pool with USDG.
- Market creators and liquidity providers take 75% of every trading fee, paid on the spot.
- Trades are signed from your own wallet, and the terms say the protocol cannot move your funds.
- Splitting or merging complete sets, adding liquidity and redeeming carry no fee.
- The 2% trading fee buys and burns $PSWAP, and any user can trigger the buyback.
Cons
- Native markets are all expired, and the last one closed on 30 September 2026.
- Native market volume topped out around $53, so the pools are too thin for real size.
- The team is anonymous, with no company name, no support email and no public API docs.
- The first $PSWAP token on Solana was abandoned, and the team says Believe sold about 10% of its supply.
- The terms say the protocol has no third party audit, and no admin can pause redemptions or reverse a trade.
- The Polymarket feed and the Expiration Sniper page often failed to load during checks.
- Kalshi trades open in a new tab on Kalshi's site instead of filling inside PredictionSwap.
- The AI analysis is described in marketing copy but does not show up as a separate feature on the live site.
Our verdict
PredictionSwap earns its keep as a free odds board: it pulls live Kalshi and Limitless markets into one feed, and the "same question on Polymarket" lookup on Kalshi pages is a small thing done well. The rest is harder to recommend. Its own Robinhood Chain markets have all expired, per-market volume topped out near $53, and nothing new has listed since late September 2026, which leaves the 2% trading fee and the $PSWAP buyback and burn with nothing to feed on. Check prices here, then go place the bet on the venue itself.
Is PredictionSwap safe & legit?
PredictionSwap comes from an anonymous solo developer with no company name, no team page and no support email, and its terms say it has no affiliation with Polymarket, Kalshi or Limitless. I found no evidence of a scam or stolen funds, and users who stuck around say the team kept building after a rough start, but the project has been dormant since 24 September 2026 with no new native markets and buybacks stopped about 52 days ago. The main red flags are no third party audit, very thin liquidity on its own markets, an abandoned first token on Solana, and a second token that most of the chatter centers on.
