Kramma

Stop guessing what a price is telling you.

Prediction markets give you a number and nothing else. Kramma tells you whether that number is worth acting on, whether your own judgement has been any good, and who is standing on the other side of the trade.

Three questions a price will not answer

Is this actually worth taking?

A gap between two venues looks like money until you try to take it. You get the figure you would actually be left with, so you can walk away from the ones that only look good.

Am I any good at this?

Winning and being right are not the same thing, and a lucky run feels identical to skill while it lasts. You get a straight answer about your own record, today, without having kept notes.

Who is on the other side?

Every trade has someone taking the opposite view. You get to see whether that is a thousand people quietly agreeing or one very large position, and whether they have a history of being right.

What you get

Six tools. Each one replaces a guess with an answer.

01Terminal

See both venues in one place.

Every market from Polymarket and Kalshi together, with the same event on both venues shown side by side. Search, filter, and find what you care about without opening two tabs.

Otherwise you are checking two sites by hand and missing whichever one you did not think to open.

02Arbitrage

Know if a gap is worth taking.

The number you would actually keep, after everything the trade costs you. Ranked, so the ones worth your attention are at the top and the traps are visibly negative.

Otherwise a four point gap looks like free money right up to the moment it is not.

Open arbitrage
03Audit

Find out whether you are any good.

A real scorecard in seconds: how accurate your calls have been, whether you are beating luck, and how much is riding on a single position. Nothing to sign up for and nothing to install.

Otherwise you learn whether it was skill or luck the expensive way.

04Positioning

See who is on the other side.

Whether the opposite view is held by a crowd or by one very large position, and what that holder's track record actually looks like.

Otherwise two markets showing the same price look like the same bet, when one of them is a single opinion.

Open positioning
05Sentiment

See what people changed their mind about.

The biggest shifts in what the crowd expects, as they happen, across politics, economics and world events. Useful whether or not you ever place a trade.

Otherwise you see today's number with no idea whether it arrived quietly or moved twenty points this morning.

06Method

Check our working before you trust it.

Every rule we apply, written out plainly, including the ones that make our own results look worse. You can decide for yourself whether a number has earned your money.

Otherwise you are taking an analytics product on faith, which is how people trade on an edge that was never there.

What this will not do

  • It will not place your trade

    Kramma tells you what a number is worth. Acting on it is yours, and by the time you do the price may have moved.

  • It will not score your Kalshi account

    Wallet scoring covers Polymarket today. Everything else works across both venues.

  • It will not pretend to know everything

    Where coverage is thin, the page says so and prints the number rather than glossing over it.
