Insider trade on Splunk acquisition?

I don't know if this is genuinely suspicious or not. Is buying 20K of options an unusual thing? Or is this something that happens regularly with options expiring worthless or with a small gain - and it just happened to hit big this time?

IE "someone bought a lottery ticket and won" - interesting to know if they play the lottery every other day (and don't usually win?)

"short-dated out-of-the-money call options that cash out a day after a merger/acquisition" is, like, the definition of a suspicious transaction. Somebody's gonna get a knock on the door from the SEC.

Maybe unless that person was a US senator/congressperson.

This is false. Then-sitting Congressman Chris Collins (R-NY) pled guilty and was sentenced to 26 months in prison for insider-trading back in 2019-2020. He was pardoned by President Donald Trump as one of his last official acts as President, but Collins still spent 10 weeks in prison for insider-trading as a sitting congressman (this was for knowledge he gained outside of his duties as a congressman, it was knowledge he got as a member of the Board of a company).

Congresspersons separately aren't allowed to trade on things they learn from their job- that was banned in 2012 under the STOCK act.
