Help and contact

Prices come live from Kalshi and Polymarket, and we only show one once the live feed has confirmed it, so a price can take a few seconds to appear. If it stays missing or looks old for more than a minute, reload the page or reopen the app. If it still looks wrong, send us a message.

Use the same method you signed up with. If you asked for a code by email and it has not arrived after a couple of minutes, check your spam folder and ask for a new one. If you still cannot get in, send us a message with the address you are trying to use.

Orders are placed on Kalshi or Polymarket, in your own account there. Zena never holds your money. Check the order's status on the venue first, then send us a message if what you saw here differs from what the venue shows.

On iPhone, check that notifications are allowed for Zena in Settings. If they are and alerts still do not arrive, send us a message with the market and the alert you set.

Summaries of news and public discussion are limited per person and per day to keep Zena reliable. When a new one is not available you see the last one, or a note saying so. Prices and fair values are never affected.

What a contract costs right now, in cents. A contract pays 100 cents if the outcome happens and nothing if it does not.

Zena's estimate of where the price is likely to move, from the market's own trading and order book. It is a research estimate, not a promise.

The gap between fair value and the price, shown only when it is large enough to act on after the cost of crossing between buyers and sellers.

Send us a message with the email address on your account. We will confirm with you by email, then delete the account and the data attached to it.
