Fresh Markets
Just-listed markets, before the flow finds them.
The tool runs at /fresh and needs a $49.99/mo membership. There is no free tier and no trial, so opening it signed out lands on the pricing page rather than the board. This page is the open documentation of what it does.
Fresh boards misprice first. An early book is thin, often set by a single market maker, and slow to calibrate — which is exactly why experienced traders check new listings before the crowd arrives. This board lists what opened on either venue in the last seventy-two hours, newest first.
It cuts both ways, and the page says so: thin books also slip, so a wrong-looking number you cannot fill at size is a quote rather than an edge.
How Polymarket listings are found
Polymarket's catalog can be ordered by creation time, which is the honest listing moment — a scheduling field would put five-minute crypto markets in the wrong order entirely. The crawl reads the newest raw pages, which surfaces brand-new boards within minutes of listing regardless of whether anything has traded on them.
Beyond a few hours the upstream pager runs into a hard depth cap, so the rest of the seventy-two-hour window is covered by pages filtered to markets carrying at least five hundred dollars of daily volume. The consequence is stated plainly on the board: older Polymarket listings appear here only once they have some volume.
How Kalshi listings are found
Kalshi's plain market listing is unusable for this: it opens with an enormous block of auto-generated multi-variant parlay legs, so paging it backwards never reaches a real new board. The crawl uses the open-events feed instead, which does not carry those parlay markets at all, and reads each nested market's official open time.
That gives complete coverage of every open non-parlay board on the venue regardless of volume — the opposite trade-off from the Polymarket side, and worth knowing when comparing the two halves of the list.
Collapsing the robot series
Recurring auto-listings would bury everything. Five-minute crypto up-or-down markets, per-player prop batches, per-strike ladders and per-team season boards all list continuously. Each family is collapsed to its newest few rows — two per Polymarket family, three per Kalshi series — and the board is capped at around a hundred and twenty rows.
Family identity comes from the parent event's series where the venue provides one, then the event, then the market slug with numeric and strike-shaped tokens stripped.
Reading the price column on a market nobody has traded
The price shown is the last trade when one exists. Failing that it is the mid of a two-sided book, and failing that the executable ask. A dash means there is genuinely nothing: no trade and no quote.
That distinction matters more here than anywhere else on the site, because a brand-new board frequently has one resting order and no history at all.
What it cannot tell you
Every tool has a boundary, and knowing where it sits is the difference between using one well and being misled by it. For Fresh Markets:
- New books are thin. A displayed price can be stale, unfillable at size, or set by a single resting order.
- Polymarket coverage past the first few hours is volume-gated by an upstream paging cap, so a quiet listing from yesterday may not appear.
- The board says a market is new. It says nothing about whether its price is wrong.
- Family collapsing is deliberate suppression. If you specifically want every rung of a strike ladder, this is the wrong board.
- Auto-generated multi-variant parlay markets are excluded by construction on the Kalshi side.
- Resolution rules on a brand-new market deserve a full read on the venue before any trade. A fresh listing is exactly where an unexpected criterion hides.
What it is built on
- Polymarket gamma /markets ordered by creation time, both unfiltered and volume-filtered, unioned.
- Kalshi trade-api v2 /events with nested markets, filtered by each market's open time.
- Kalshi's public artwork feed, for row icons only — it degrades to a category glyph and never blocks the crawl.
