alt Hacker NewsI work for an HFT (not Jane Street) so I am biased, but we (the HFT industry as a whole) are quite small compared to big tech.
I’d estimate the total global HFT revenue to be 100 billion dollars a year, which is less than Apple and a tiny percentage of all big tech combined.
I would love to talk more with you about HFT work :) i am working in one myself! Please email [email protected] if you wanna have a chat!
