Field Guide

No. gap133 is read-only. It never asks for your wallet, your keys, your seed phrase, or an exchange login. Nothing on this site can move your money. You always trade on the venues themselves, through their own apps.

No. gap133 shows you a price difference and nothing else. What you do with it is your decision. Prediction markets involve real risk, including the risk of losing everything you stake. Nothing here is trading advice or a solicitation.

Different audiences, different capital, different speeds. Kalshi is a US-regulated exchange settled in dollars; Polymarket is a crypto-native venue settled in USDC and restricted for US traders. Different participants see different news, at different times, with different risk appetites. The disagreement is structural, which is why it keeps appearing.

No, and be suspicious of anyone who says otherwise. Capturing a gap usually means holding positions on both venues, which introduces settlement timing, fee, and venue-risk considerations. gap133 shows you the signal; managing risk stays your job.

We rescan the whole board every few minutes. Free views run 10 minutes behind. Desk keys see each scan as soon as it lands.

It is our matcher's confidence that the two rows are really the same event. Matching is done by title and meaning, and it is deliberately conservative: a pair scoring under 65 percent only reaches the board if Jev, the verification model that reads both venues rules, signs off on it, and any pair showing an implausibly wide gap (25 cents or more) is demoted automatically, because wide gaps almost always mean the questions are subtly different (a nominee market versus an election-winner market, for example). We would rather hide a real gap than show you a fake one.

The gap is the edge at the touch: what you capture buying one venue at its ask and selling the other at its bid, before fees. We used to lead with the plain price difference, but when one book is wide that number means nothing (a 12c bid and 66c ask once showed a 55c difference with 1c actually tradeable), so it now sits underneath as the quote gap, for context only. When the edge is zero or negative the row says inside spread and is dimmed. Net is the edge at the touch minus both venues taker fees at the prices you would actually trade (we read the fee terms Polymarket publishes for each market, and round the Kalshi fee up per order the way Kalshi does). The net + badge means the trade survives real costs and the settlement terms match closely. Size is how many contracts you could trade on both venues at the touch: the smaller of the two order-book legs. Each contract pays $1 at settlement, and putting on both legs ties up roughly $1 per contract in total. Together they answer the only two questions that matter about a gap: is it real after costs, and is it real at size.

A green both live badge means both venues printed a trade within the last 24 hours. If one side has gone quiet, the row is marked stale and demoted to grey: a price that stopped moving is a fossil, not a quote. If a venue returns no trade data at all, the row says unverified and is treated the same way. Stale and unverified rows never get net + and never trigger alerts. This gate exists because showing stale prices next to live ones is how scanners manufacture fake gaps.

Three gates. A deterministic matcher proposes the match and blocks questions that share words but ask different things. Then Jev (a probabilistic decision model) reads both markets resolution rules and answers two questions: is it the same event, and do the venues settle it on the same terms? Different-event pairs are dismissed, unsure ones are held, and every pair on the board is labelled same contract, close terms or terms differ. Then the staleness gate checks both venues are still printing. The full evidence trail for every pair is public on the matching audit page.

Both markets are about the same event, but the venues settle them differently in some scenarios: a different deadline, interim or acting holders counted on one venue and not the other, or an incumbent staying handled differently. Part of the gap is the price of that difference, so it is not free money, and we never mark those gaps net positive. Open the row to see both deadlines.

Robinhood Stock Tokens trade on Uniswap pools on Robinhood Chain around the clock. The Stock Tokens page compares each pool price with the Chainlink reference Robinhood publishes for the same token, then subtracts the pool fee, because a pool can sit anywhere inside its fee without anyone being able to trade the difference. Only pools with real depth are shown; most Stock Tokens still sit in empty placeholder pools, which we count and leave out. Weekend gaps are drift against a frozen reference and usually close when trading resumes. Stock Tokens are not available to US persons and are restricted in several other places. We only show prices; we never route trades.

They are in the review band: pairs the matcher proposed but the gates did not clear. The matching audit page shows all of them with their scores, Jev probabilities, and dismissal state. Transparency about what we are unsure of is a feature, not a bug.

Markets close and resolve; volumes shift; the matcher improves. The board is a live view, not a history. Every market has a gap chart: free visitors see the last 24 hours, desks see 90 days.

You found the theme switcher in the header. Day is Daylight (light theme), Nite is Midnight Tape (dark theme). Chrome is the desk-keyholders skin; the padlock means it needs a paid key. Your choice is remembered on this device.

Your desk key is sent after your transaction confirms on-chain, usually within the hour. Visit the unlock link in that email once and the board goes live in that browser. Each desk key runs for 30 days from when we issue it; when you renew, we extend the same key, so there is nothing to set up again.

Email hello@gap133.xyz within 7 days of payment and we will sort it out. We would rather refund fast than have an unhappy desk holder.

gap133 is a data service and works anywhere the site loads. But the venues themselves have their own restrictions: Polymarket restricts US traders, and Kalshi serves US residents. Check your venues terms before you trade. gap133 shows data; it does not grant trading access.

gap133 is an independent, bootstrapped product. No VC, no token, no roadmap promises. It makes money the honest way: people pay for the data because it is worth paying for.
