Kalshi Fine Print Watch: The 10 Biggest Markets, Graded A-F
Updated August 10, 2026 · 13 min read · by Jake Hari
Every Kalshi market has two layers. The headline is the question traders think they are trading. The rules text is the question they are actually trading. Most of the time the two match. Sometimes they do not, and the gap only becomes visible on settlement day, when it is too late to do anything about it. This is Edition 1 of Fine Print Watch, a weekly column with one job: we pull the ten highest-volume open markets on the exchange, read the full settlement rules behind each headline, and grade the gap from A to F. The rules are public. We are just the ones reading them.
The Quick Answer
We graded the ten biggest open Kalshi markets by lifetime volume, plus one dishonorable mention. The distribution: one A, two A-minuses, one B-plus, one B, one C-plus, one C, three Ds, and one F. The F belongs to the single most-traded open market on the exchange: the tech layoffs contract, whose ticker still displays a strike of 494,000 while the binding rule settles at 447,000, and whose reimbursement window for traders caught in that gap closed back in March. The full board, and the exact clause behind every grade of C or worse, is below.

Rules text, prices, and volume figures on this page were fetched from Kalshi's public API on August 10, 2026, and every quoted clause is verbatim from the market's own rules as of that fetch. New to event markets? Start with how Kalshi contracts actually work. This column is not a how-to checklist; it is a graded public record, re-run weekly on this URL, and when a grade changes because the rules changed, that change is the story.
How The Grades Work
The grade measures one thing: how faithfully the headline question describes what the rules actually settle. An A means you can trade the title. An F means the title and the rules have parted company on something that decides who gets paid.
- A: headline matches rules. What you think you are buying is what you are buying.
- B: matches, with a clause worth knowing before you size up.
- C: a settlement condition materially broader or narrower than the headline suggests.
- D: the rules change the trade in a way most holders likely do not know.
- F: the headline actively misleads about a term that decides settlement.
Five trap classes show up over and over in this lane, and our panel coverage has been burned by, or caught, each one: definition traps (the rules define a key verb more broadly or narrowly than everyday English, the way "perform" is not the same word as "sing"), timing traps (the settlement clock differs from the headline clock), source-hierarchy traps (the question is settled by a specific named source or committee, not by reality in the abstract), carveout traps (a buried exception rewrites the payout in a specific scenario, the class made famous by leader-exit markets and their death clauses), and dead-contract listings (a market that stays open and tradable after its premise has quietly expired). Every grade below names its class.

The F: Tech Layoffs, A Strike That Says One Thing And Settles On Another
The most-traded open market on Kalshi, at 31.4 million contracts, asks a clean question: "More tech layoffs in 2026 than in 2025?" The primary rule settles it with one number: "If there are more than 447,000 layoffs in the information sector in 2026, then the market resolves to Yes."
Here is the problem. The ticker is KXLAYOFFSYINFO-26-494000. The market was listed against a 2025 baseline of 494,000, and Kalshi's own secondary rules say plainly that this was wrong:
"This market was listed using an incorrect underlying value for tech layoffs in 2025. The correct floor strike is 447,000 layoffs, not 494,000 as currently specified. If the final layoff count falls between those two numbers, we will pay out $1.00 to all traders with an open position as of March 13, 2026 at 5:00 PM ET. Trades executed after this time are not eligible for reimbursement."
Read that last sentence twice, because it is the burn clause. The reimbursement that protects traders caught between the two strikes applies only to positions held as of March 13, 2026. That window has been closed for five months. Anyone trading today off the number in the ticker is trading a strike that does not exist: if the 2026 count lands anywhere between 447,000 and 494,000, this market resolves YES, and a NO holder who bought after March 13 believing the bar was 494,000 collects nothing. A separate wrinkle: the one-sentence primary rule never names which official series counts the layoffs. Kalshi's series metadata points at the layoffs-and-discharges series for the information sector on FRED, but the market's own rules text leaves the source unnamed. Headline says one number, ticker says another, binding rule says a third thing about who was protected. That is what an F looks like. We wrote up the full anatomy of this listing in our tech layoffs market breakdown.
None of this is hidden, and that is the point of this column: every word above is published, in public, in the market's own rules tab. It is simply the case that 31 million contracts have traded against a headline whose fine print rewrote it.
The Ds: A Basket In Disguise, A 24-Hour Clock Gap, And A Death Clause
The Citrini Recession Basket: 25.9 Million Contracts On A Title Nobody Can Parse
The third-biggest open market on the exchange has a title that is, in full: "Will the number of unemployment rate exceeds 10% (monthly BLS); S&P 500 declines more than 30% from its closing level on Issuance; Zillow Home Value Index declines more than 10% YoY in any of: NYC, LA, San Francisco, Chicago, Houston, Phoenix; labor share of gross domestic income (GDI) first-release value for any quarter falls below 50%; CPI-U (All items, not seasonally-adjusted) YoY falls below 0% in any monthly release during before July 2028 be above 2?"
That is not a transcription error. The listing machinery concatenated five separate recession indicators into a single headline and asked whether the count "be above 2." The actual rule is coherent once you find it: the market resolves YES if at least three of the five conditions occur in any data release published before July 2028. But a trader has to reverse-engineer that from a garbled title, and the legs hide their own fine print. The sharpest example:
"S&P 500 declines more than 30% from its closing level on Issuance"
That is a decline measured from the index's closing level on the day the market was issued, not from any high. If the S&P runs up 40% and then falls 35% from its peak, that leg may still not trigger, because the drawdown is anchored to a fixed historical closing print, not to where the market has been. Traders who read "S&P falls 30%" as "a bear market happens" are trading a different contract than the one listed. One more detail worth knowing: the series-level settlement-source field for this product, as returned by Kalshi's own API, currently reads "The Source Agencies are" and then stops. An unfinished sentence, in production, on a market carrying 25.9 million contracts. The five legs each name their underlying series in the rule text, which is why this is a D and not an F, but the packaging fails every readability test an exchange listing can face.
Bitcoin $200K: The Title And The Rules Disagree By 24 Hours
The headline: "Will Bitcoin be above $200000 by Jan 1, 2027 at 11:59PM ET?" The primary rule: "If the Bitcoin spot price according to the CF Bitcoin Real-Time Index is above $200000 starting 2025-10-10 and before Jan 1, 2027 at 12:00 AM ET, then the market resolves to Yes." The title promises the end of January 1. The rule stops at the stroke of midnight that begins January 1. That is a full day of headline that the settlement clock does not cover, on a market whose entire question is whether a threshold gets touched in time. The market's own expiration timestamp agrees with the rule, not the title.
The second clause is stranger. The secondary rules describe the resolution value like this:
"The resolution value is calculated by taking all BRTI values for each minute from market issuance until the specified time on the target date, removing the top 20% and bottom 20% of values, then averaging the remaining 60% of values."
The same paragraph also says the market "immediately resolves" if the index crosses the threshold at any point. Those two sentences describe different contracts. A one-touch market pays the moment the index prints above $200,000. A trimmed-mean market averages the whole life of the contract and throws away the top fifth of every reading, which is precisely where a brief spike above $200,000 would live. We are not alleging anything here beyond what the text says: the rules contain both mechanisms, and a trader cannot tell from the published language which one governs a spike that lasts an afternoon. On a 4-cent lottery ticket whose value is entirely in the spike scenario, that ambiguity is the trade. Our model panel's read on the underlying probability is on the Bitcoin $200K verdict board.
Dishonorable Mention: "Trump Out Before 2027" And The Carveout Class
At 5.7 million contracts this market sits just outside the top ten, and we are grading it anyway, because it is the cleanest live example of the carveout class. The headline reads like a simple exit market: YES if Donald Trump leaves office before January 1, 2027. Then the secondary rules do two things the headline never hints at. First, they widen the trigger: "An announcement that the President will leave the office within the next year is also encompassed by the Payout Criterion." An announcement, not a departure. Second, and far more importantly, they carve out death:
"If Donald Trump leaves solely because they have died, the associated market will resolve and the Exchange will determine the payouts to the holders of long and short positions based upon the last traded price (prior to the death)."
Sit with that. In the one exit scenario that dominates most holders' mental model of a 5-cent YES ticket on this question, the contract does not pay $1. It settles at wherever the market happened to be trading before the news. A YES holder who bought at 5 cents collects roughly 5 cents. This is the same clause family that shaped the Khamenei exit markets, it is standard across this product line, and it means the headline price is not measuring what most buyers think it is measuring. The market is not mispriced; it is misread. The fine print is doing exactly what it says. You just have to have read it.
The Cs: Aliens, And Who Exactly Speaks For The House
"Will The U.S. Confirm That Aliens Exist" Is Broader Than It Sounds
The second-biggest open market, 26.8 million contracts traded and a remarkable 9.5 million still held open, resolves YES if before 2027 "the President, any member of the Cabinet, any member of the Joint Chiefs of Staff, or any US federal agency definitively states that extraterrestrial life or technology exists."
Two definition gaps earn the C. The first is "extraterrestrial life or technology." The headline word is "aliens," and the mental image is disclosure of intelligent visitors. The rule as written covers any extraterrestrial life. On the text, a federal agency announcing conclusive evidence of ancient microbial life in a Mars sample is an announcement that extraterrestrial life exists. Whether that was the intent is unknowable from the outside; it is what the words say. The second gap is "definitively states," which is doing an enormous amount of unquantified work. Government officials have made striking statements about unidentified phenomena for years without any of them counting as definitive. The rules also define "Cabinet" expansively, sweeping in the EPA Administrator, the CIA Director, the UN Ambassador, and a dozen other officials. Broad triggers, one undefined adverb: a 6-cent price on a question whose settlement bar lives entirely inside the word "definitively."
House Control: Settled By Media Consensus, Or By One Person's Party Card
The House control market reads like the simplest question in politics: "Will Republicans win the House in 2026?" The fine print names its judges, in order:
"This market may be determined early based on a consensus of media calls projecting control of the U.S. House. … Otherwise, victory will be determined by the party identification of the Speaker of the House on February 1, 2027."
This is a source-hierarchy trap in both directions. The fast path is a consensus of media projections, which is a judgment about coverage, not about certified seat counts. The backstop is stranger: absent that consensus, the market settles not on which party won more seats but on the party of whoever holds the Speaker's gavel on a specific Wednesday. Speaker elections are not formalities anymore; the January 2023 election ran to fifteen ballots. In a narrow House, a prolonged Speaker fight or a compromise Speaker turns "who won the House" into "who was Speaker on February 1," and those are not always the same question. The grade is C-plus rather than lower because for the overwhelming majority of outcomes the two questions agree, and the early-determination mechanism is disclosed right in the rules summary. But a 16-cent contract on the Republican side is partly a bet on parliamentary mechanics that the headline never mentions. As always in this column, that is a mechanical observation about settlement plumbing, not a view on any party's chances.
The Bs And As: What Clean Fine Print Looks Like
SAVE Act becomes law before Jan 4, 2027 (B+). The rule matches the headline: YES if H.R. 22 becomes law before the deadline. "Becomes law" is a well-defined event, signature or veto override, and the deadline is stated identically in both places. The only blemishes are cosmetic: the secondary rules field literally contains the unfilled template header "|| Additional Info ||" and nothing else. Someone shipped the placeholder. It costs traders nothing, and it tells you something about how much human review these text fields get.
Gavin Newsom for the 2028 Democratic nomination (B). The rule adds one word pair the headline omits: YES if Newsom "wins and accepts the nomination." On a 47-name board, acceptance is a real condition, not boilerplate. A candidate can be the presumptive nominee for months without being the nominee; the market pays on the convention, not the coronation. The same clause structure sits under every name on the board, including on the full 2028 Democratic nominee verdict page where our panel prices the field. Worth one grade step, nothing more.
Los Angeles mayor, Nithya Raman (A). "If Nithya Raman wins the 2026 Los Angeles Mayoral Election, then the market resolves to Yes." That is the whole primary rule. No source ambiguity that matters, no carveouts, no clock games. The headline is the contract. This is the reference point every other grade on this page is measured against.
Fishback for Florida GOP governor nominee (A-) and California governor, Steve Hilton (A-) are nearly as clean. Both settle on a well-defined public event, the nomination and the election respectively, and both disclose their early-close mechanics up front. The California market notes it can settle early "after a consensus of media organizations project the winner," the same media-consensus device the House market uses, disclosed plainly. Half a grade off the top for leaning on projection consensus rather than certification, which has almost never mattered and occasionally has.
What This Column Is, And What It Is Not
Nothing above is an allegation of bad faith. Every clause quoted in this piece is published by Kalshi, in public, on the market's own rules tab, before anyone trades a single contract. Exchanges write fine print for the same reason insurers do: edge cases are real, and somebody has to decide them in advance. The failure mode is not the fine print existing. It is that at current market sizes, tens of millions of contracts trade against headlines while the controlling language sits one unread click away. The gap between what a market says and what it settles is measurable, it moves real money, and as of this edition it gets graded in public every week.
Grades will change. When Kalshi corrects a listing, the grade goes up and we will say so. When rules text is edited mid-flight on an open market, that is bigger news than any grade, and this column is where we will publish it. Where our model panel has scored a graded market's underlying probability, we cite those numbers as model estimates, not predictions of fact and not financial advice; every one of the panel's calls is graded against real settlements on the public scoreboard. Kalshi is a CFTC-regulated event-contract exchange open to eligible U.S. users 18+ (18 and older), and availability varies by state as of August 2026. Books on several markets covered here are thin, with wide spreads; the executable price can differ meaningfully from the last print quoted above.

The Bottom Line
Eleven graded markets, 165 million lifetime contracts among them, and the fine-print scorecard reads: three headlines you can trade on sight, four that ask one extra reading, and four where the rules rewrite the ticket. The most-traded open market on the exchange carries a strike its own ticker misstates. The rules were public the whole time. Edition 2 runs next week on this URL, same grades, fresh reads, and any market that fixes its language gets its upgrade in print.
