"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.

If they obtained info about this through their role as a senator/congressperson, and not just through normal channels. If I understand it correctly:

Insider trading off of classified or whatever info they get from their senate/congress job - not illegal (though imo it should be illegal). (Edit: as mandevil points out, strictly speaking illegal, but largely uneforceable/unenforced)

Insider trading off of info they got from their buddy at XYZ place who knew about something ahead of time, unrelated to their senate/congress job - still illegal, same as for other people.

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.

But lottery-ticket options trading is done all the time. The fact that the options expire the next day is part of the strategy (because before that, the options cost more). $20k might sound like a big stake but you don't know the size of the trader's portfolio, it might be 0.01% of it, and they didn't stand to lose the whole thing necessarily.

All true in the abstract. But doing it the day before an acquisition is always gonna earn you a door knock, even if you're a serial gambler.

Yeah, this is not that suspicious IMO. The trade was opened yesterday when Splunk was at $119. They just needed a 7% gain by Friday to be profitable on their $127 calls. Traders make those kind of gambles all the time.
