+# Polymarket Token Launch Catalyst Markets
+
+Clean Polymarket token-launch catalyst data with launch, airdrop, FDV-threshold, listing, deadline, liquidity, and priority fields for crypto research workflows.
+
+**This is a free preview.** Load it instantly, inspect the schema, and validate quality before purchasing the full dataset.
+
+---
+
+## What This Preview Proves
+
+- **Sample rows:** 60 (full dataset: 600 rows)
+- **Columns:** 113 fields, fully described below
+- **Format:** parquet (loads in pandas, HF datasets, or any parquet reader)
+- **No authentication required** to load this sample
+- **Schema and quality** are identical to the paid full dataset
+
+---
+
+## Upgrade to Full Dataset
+
+The full production dataset contains **600 rows** across **113 columns**.
+
+**Purchase here:** [https://thearticulated.gumroad.com/l/jfremu?utm_source=hf_sample_readme&utm_medium=referral&utm_campaign=polymarket-token-launch-catalyst-markets](https://thearticulated.gumroad.com/l/jfremu?utm_source=hf_sample_readme&utm_medium=referral&utm_campaign=polymarket-token-launch-catalyst-markets)
+
+After purchase, provide your Hugging Face username and request access on the [full dataset page](https://huggingface.co/datasets/Karmane/polymarket-token-launch-catalyst-markets).
+
+---
+
+## Quick Start
+
+```python
+from datasets import load_dataset
+
+dataset = load_dataset("Karmane/polymarket-token-launch-catalyst-markets-sample")
+df = dataset["data"].to_pandas()
+print(f"Rows: {len(df):,}, Columns: {len(df.columns)}")
+print(df.head())
+```
+
+Or with pandas directly:
+
+```python
+import pandas as pd
+df = pd.read_parquet("hf://datasets/Karmane/polymarket-token-launch-catalyst-markets-sample/data/data.parquet")
+print(df.head())
+```
+
+---
+
+## Use Cases
+
+- Track token launches, airdrops, exchange listings, and launch-day FDV threshold contracts without flattening the broader Polymarket crypto feed yourself.
+- Rank catalyst markets by liquidity, volume, deadline urgency, and tradability for analyst queues, dashboards, or launch calendars.
+- Group contracts by project name and compare active versus closed catalyst markets inside one parquet dataset for notebooks, BI, or newsletter research.
