The last time The Oracle spoke with Max “Primo Data” Mershon, he was an indie developer working on Polymarket Analytics, the OG prediction market data provider.
Fast forward to today and he’s a member of the Polymarket data team and just released data.polymarket.com, a dashboard showing daily exchange volume on Polymarket’s U.S. and international exchanges.
We caught up with Primo to understand how prediction market volume gets counted, and what the data is telling us about Polymarket’s two exchange businesses.
