| # Polymarket Crypto Up/Down Market Metadata |
|
|
| Raw Gamma event metadata for every crypto up/down market on Polymarket |
| during March 1 - June 3, 2026 (UTC), for BTC, ETH, and SOL on the |
| 5-minute and 15-minute timeframes. |
|
|
| ## Structure |
|
|
| ``` |
| data/ |
| raw/ |
| metadata/ |
| <asset>/ # btc, eth, sol |
| <timeframe>/ # 5m, 15m |
| _manifest.json # series-level manifest (expected/fetched/missing/failed) |
| <DD-MM-YYYY>/ # UTC day folder |
| <HH-MM-SS-UTC>/ # UTC time folder (window start) |
| metadata.json # raw Gamma event for this window |
| ``` |
|
|
| Total: **108,276 market files** across 6 series (3 assets x 2 timeframes), |
| plus 6 series-level `_manifest.json` and a cross-series index at |
| `data/raw/_index/by_window.jsonl`. |
|
|
| ## What's in each `metadata.json` |
|
|
| The full raw Gamma `/events` response for one market, including: |
| - `id`, `slug`, `title`, `description` |
| - `startDate`, `endDate` (UTC ISO 8601) |
| - `active`, `closed`, `archived`, `new` |
| - `markets[]` — array of inner markets (typically 1) with `conditionId`, |
| `clobTokenIds` (UP and DOWN token IDs), `volume`, `liquidity` |
| - `tags[]`, `image`, `icon`, etc. |
|
|
| ## Coverage |
|
|
| | Series | Windows | Missing | |
| |---|---|---| |
| | btc/5m | 27,068 | 5 | |
| | btc/15m | 9,025 | 0 | |
| | eth/5m | 27,066 | 7 | |
| | eth/15m | 9,025 | 0 | |
| | sol/5m | 27,067 | 6 | |
| | sol/15m | 9,025 | 0 | |
|
|
| **18 windows are genuinely absent from Polymarket's history.** They cluster |
| on 3 specific clock-times across 3 specific days (all on 5m markets, all 3 |
| assets). The collector recorded them in each `_manifest.json`'s |
| `missing_slugs` list. See the manifest for exact slugs. |
|
|
| ## Slug convention |
|
|
| `{asset}-updown-{timeframe}-{window_start_epoch}` where |
| `window_start = (unix_ts // duration_seconds) * duration_seconds`. The |
| window is `[T, T+duration)` and the slug encodes the start, not the close. |
|
|
| The 5m and 15m market windows close at `T+300` and `T+900` seconds |
| respectively. |
|
|
| ## Loading this dataset |
|
|
| The dataset preserves the on-disk structure, so you can: |
|
|
| ```python |
| from huggingface_hub import snapshot_download |
| path = snapshot_download( |
| repo_id="krish301/polymarket-crypto-metadata", |
| repo_type="dataset", |
| ) |
| # Walk the tree |
| import os, json |
| for root, dirs, files in os.walk(os.path.join(path, "data", "raw", "metadata")): |
| for f in files: |
| if f == "metadata.json": |
| full = os.path.join(root, f) |
| with open(full) as fh: |
| ev = json.load(fh) |
| # ev["slug"], ev["endDate"], ev["markets"][0]["clobTokenIds"], ... |
| ``` |
|
|
| Or browse the tree in the HF dataset viewer at: |

|
|
| ## Provenance |
|
|
| Generated by the `polymarket_bot.data_collection` package: |
| - `slug.py` — slug builder and window-sweep generator |
| - `gamma.py` — async Gamma client with retry/backoff |
| - `collect_metadata.py` — backfill CLI |
| - `verify.py` — independent post-collection verifier |
|
|
| Collection period: 2026-06-04. See per-series `_manifest.json` for |
| exact fetched_at timestamps. |
