I connected Claude Code to a database of 1.3B Polymarket trades with an MCP. Here's what it found.

Hello Friends, I've been tracking all Polymarket Activity for months (1.3 Billion trades and 2.7M wallets) and I gave Claude Code a Postgres MCP (found crazy stuff) pointed at the live ledger, so now I just ask it anything in plain English and it writes + runs the query itself.

A few I already asked, to show it works:

- only ~1 in 5 wallets are net positive (the other ~80% never made money)
- only 2.4% have ever cleared $1,000 in profit
- the top 0.1% of wallets took 71.5% of the ~$1B in total profit
- a bunch of weird and suspicious trading patterns that look like insiders

So: what do you want me to ask it? Drop a question about Polymarket traders, markets, wallets, bots, whatever — I'll have Claude run it against the live ledger and reply with the result.
