In the first post we said every market is a simple yes-or-no question. That's true, but it skips over the part that actually determines whether you get paid: how the contract is built. An event contract isn't just a question. It's a question plus a set of rules that decide, with no ambiguity, exactly what counts as a win. Understanding those rules is the difference between trading a market and gambling on your own interpretation of it.
Let's open the hood.
Every contract starts with a precise question
A contract begins as a claim that can only be true or false. "Will Team X win their match on Saturday?" "Will the unemployment rate come in above 4% this month?" There's no "kind of," no partial credit. When the event concludes, the answer is either yes or no, and every contract settles accordingly.
The wording matters more than beginners expect. A market might ask whether a team "wins," which raises a question the contract has to answer in advance: does a draw count? Does overtime count? Good event contracts spell this out before a single trade happens, so there's never a debate about the result after the fact.
The settlement source is the whole game
This is the part most new traders overlook, and it's the most important structural feature of any contract: every market names, up front, the exact source that will decide the outcome.
Economic markets settle against official government releases, like Bureau of Labor Statistics jobs numbers or the Federal Reserve's rate decisions. Weather markets settle against National Weather Service and NOAA data. Sports markets settle against the official final result. The source is written into the contract before you can trade it, which is what keeps the process objective. You're not relying on someone's judgment call. You're relying on a number that a named authority will publish.
Occasionally an outcome is genuinely ambiguous, and Kalshi has a defined process for that too, including an outcome review committee and, in rare cases, settling at the last traded price. But the default is simple: a predefined, objective source calls the result, and the contract pays out from there.
Trading windows and settlement are two different moments
Every market has a window when you can trade it, and a separate moment when it settles. Those are not the same thing, and confusing them is a classic rookie mistake.
Trading opens when the market goes live and stays open right up until the contract closes, which is usually when the underlying event is decided. Settlement is the moment the named source confirms the outcome and the contract locks to $1 or $0. Sometimes settlement follows within minutes. Sometimes, especially on markets tied to data that gets verified later, it can lag. The practical takeaway: know when your market actually settles, because that's when your money is freed up, not necessarily the second the game ends.
Two sides, one dollar, one price
We covered this in the first post, but it's worth restating inside the structure. Each contract has a Yes side and a No side, and together they always add up to $1. If Yes is trading at 58¢, No is trading at roughly 42¢. Buying the No contract is the same thing as taking the position that the event won't happen. You're not "not trading." You're actively holding the other side.
How you place the order
When you go to trade, you choose between two order types, and it's the same choice you'd make on a stock exchange.
A market order fills immediately at the best price currently available. You take the price the market is offering right now. A limit order lets you name your own price between 1¢ and 99¢, and your order waits on the book until another trader is willing to meet it, or until you cancel it. Market orders trade speed for price. Limit orders trade certainty for a better entry. Which one you use is a discipline decision, not a technical one, and it's exactly the kind of decision worth having a rule for.
Why the structure is the point
Event contracts feel simple on the surface, and that simplicity is deliberate. A binary payout, a fixed price range, and a predefined settlement source strip out almost all of the ambiguity that makes other formats messy. What's left is a clean question: is the market's price on this outcome right or wrong, and do you have a good enough reason to take the other side?
Answering that consistently, trade after trade, is where structure on your end starts to matter as much as structure on the contract's end.
That's the part BLKJ was built for. It started as one trader's personal rulebook during the 2026 World Cup and grew into a full discipline toolkit: a probability zone framework that keeps you trading in the ranges where you actually have an edge, a built in trade journal, and analytics that hold you to your own rules instead of your impulses. It connects directly to Kalshi so the discipline and the trades live in one place.
Writing the rules was never the hard part. Following them live, with money down, is. That's exactly what BLKJ solves.
