Trading Kalshi, Polymarket, and Predict.fun from three separate accounts means three KYC processes, three funding flows, and three dashboards tracking the same underlying markets. Kairos replaces that with one account. One login. One order book aggregating every major prediction market. Sub-second data across venues. You reach every market without managing them separately.
Why are prediction market accounts fragmented?
Each major venue runs on different infrastructure. Kalshi is a CFTC-regulated designated contract market that settles in USD. Polymarket runs on the Polygon blockchain and holds positions in USDC. Predict.fun runs on Solana with its own points structure. Each operates its own exchange, its own account system, and its own withdrawal route.
For a trader running positions across all three, that means split capital, separate withdrawal queues, and position tracking in three places at once. When the same event lists on two venues at different prices, closing that spread requires coordinating across accounts in real time. That coordination takes seconds a professional trader does not have.
What does a Kalshi account give you?
Kalshi is a CFTC-registered designated contract market, the same license class as CME Group. Opening an account requires identity verification and takes minutes. Deposits and withdrawals process in USD. The account gives access to binary event contracts on US politics, economics, and sports that are legal for US residents to trade.
That CFTC registration is the reason Kalshi markets are legal for US residents to trade. It is not present on Polymarket's global product or on Hyperliquid. What the Kalshi native interface does not offer is execution at the speed a professional trader needs. Order book aggregation, cross-venue pricing, and sub-second fills require a terminal built for that job, not a participation interface built for browsing.
How do you close or delete a Polymarket account?
Polymarket has no in-app account deletion option. To close a Polymarket account, you must contact Polymarket support directly. Before submitting the request, withdraw available USDC to a connected wallet. Open positions settle in USDC at each contract's resolution date, so close active contracts or wait for settlement before requesting full account closure.
Polymarket's original global product used wallet-connect with no account creation required. Transactions were signed with a crypto wallet, and there was no registration. Polymarket US, launched in 2024, added KYC and verified account creation for US-based users. That account type can only be closed through Polymarket support, not through any settings screen.
Traders looking to delete a Polymarket account are often doing it because the platform no longer fits their workflow. The absence of an in-app deletion option is itself a signal of the account friction prediction market traders deal with across every venue.
How does Kairos replace separate accounts?
One Kairos account gives you access to Kalshi, Polymarket, and Predict.fun from one terminal. Kairos aggregates the order books across venues, surfaces the global best bid and best ask for every event listed on more than one platform, and routes execution to where the price is best. The separate accounts are no longer the access mechanism.
Aggregated order books mean you see pricing across venues in one view. When the same event trades at 54 cents on Kalshi and 58 cents on Polymarket, that is a spread worth capturing. Seeing it and executing on it are two different problems. Kairos solves both. The venues keep running their own infrastructure. The fragmentation becomes invisible from your side.
Position management, cross-venue visibility, and execution routing all happen inside one interface. Capital is not split. Withdrawal flows are not multiplied. Dashboards do not diverge. Traders who have been running prediction market arbitrage across venues already know how much of their edge goes to account overhead rather than to the trade itself.
What do you need to start trading on Kairos?
A Kairos account. The terminal is free to access, backed by a16z, and designed for traders who want sub-second market data, order book aggregation across Kalshi, Polymarket, and Predict.fun, and execution that lands before the spread closes.
If you want to trade only one venue, Kairos handles it. If you want to run simultaneous positions on Kalshi and Polymarket against the same event, the terminal shows both books and routes accordingly. The accounts you have been maintaining across platforms become your choice rather than your constraint.
Kairos. One account. Every market.
