You’re thinking “bid” is in reference to Snowflake bidding for progressive as a client?
I’d say thats not likely, I work in fintech and the first thing this filename indicates to me is a CSV feed of market data for bid prices (https://en.m.wikipedia.org/wiki/Bid_price)
This is a common type of dataset a firm would dump into a datalake to use as reference data lookups against other more sensitive data (for pricing trades, etc.)
