Not the OP. I agree with what OP is mentioning. As part of the report you have to file the notional value of the underlying stock. Let's assume I buy one put option for palantir at a price of $1/contract ( say for an extremely OTM strike price of $10 ). I have paid a premium of $100. Assuming stock price of palantir is $200, the notional value I have to report is $200*100 = $20k. And not the $100 premium I paid.

This seems to back that up: https://www.sec.gov/files/form13f.pdf

FWIG you can't actually see what premium was paid on an option unless the buyer chooses to disclose that themselves.

> you can't actually see what premium was paid on an option

Nor the strike or tenor. (Options are more thinly traded than stocks. This confidentiality is practical.)
