This question is regarding the following tweet: https://twitter.com/yuriymatso/status/1281730109141954561

How was the original tweeter able to know that "Someone made a $650K bullish bet via 24 July'20 $340 calls expecting SPY to go up at least 8% in the next 2 weeks." I am not saying what he said was right or wrong but just what did he see or where he saw what data which had him conclude this statement. I am sure this was something he may have seen in the option chain perhaps. Any help or even if you could possibly point to a resource would be very much appreciated.

He circled the volume of the option in question. It was roughly 50,000 and one option contract is usually for 100 shares. Price was 0.13.

$50k*100*0.13 = 650k$

    $\begingroup$ You can see the volume of each option traded each day, so if this volume was larger than the normal volume you see trading in options... $\endgroup$
