Know the moment the two exchanges disagree.
Both venues read every 45 seconds, 380 markets matched outcome by outcome. Trader alerts fire on the first refresh a market crosses your rule: a gap, an edge after fees, or an exchange under DraftKings' fair price. Five rules, three channels, 30 days of history, an API key.
Why speed is the product
1,107 settled games scored: Kalshi's closing price closer 383 times, Polymarket's 315, identical 409. Mean gap at close $0.008. The disagreement lives intraday; a screen you check at night shows nothing.

Questions
Is a $0.03 gap actually tradeable?
Sometimes. Fees on both venues eat $0.01 to $0.02 on a round trip, so the edge-after-fees alert is the one that matters for cross-venue trades; the gap alert is for when one venue is late to a move. Both are rules you set, and every alert links to the market page so you can see the books before you act.
Why pay when there are free scrapers on Apify and GitHub?
They give you the same raw pairs we give away free here. What they do not do: refresh every 45 seconds, filter thin books and near-certain favorites, subtract both venues' fees, keep 30 days of history, or message you. You are paying for the minute between a gap opening and your phone buzzing, and for not running a scheduler.
Do you route orders or hold funds?
No, and we will not. VenueGap is read-only. You trade on Kalshi or Polymarket yourself, in your own accounts. Nothing here is advice.
What happens when the price goes up?
Nothing, for you. The price you join at is written into your Stripe subscription and never changes while you keep it, monthly or yearly. The seat counter on this page is the number of paying customers in our store, not a marketing number.
What if it is not useful?
Email hello@venuegap.com inside 7 days of your first charge and it is refunded in full, no questions. After that, cancel from your settings page in one click and it ends at the end of the period you paid for.
Which markets?
Every market both exchanges list and we can match with confidence: 35 categories, from NFL and college games to the Fed, nominations and crypto strikes. Matching is by team codes and dates for games and by outcome name for the rest; anything uncertain is dropped, not guessed.
How fast, really?
Both venues are read every 45 seconds. Trader and Desk alerts go out on the first refresh where a market crosses a rule, then not again for that market for 30 minutes unless the gap widens by another point. Game Day holds alerts and sends them every 5 minutes.
Can I put the alerts in my Discord server?
A personal server, yes, on any tier with a Discord channel. A community server with members, that is the Server licence: it adds a "via VenueGap" line to each alert, allows up to 25 webhooks and 3 admin seats, and is the only tier licensed for redistribution.
