Jane Street made ~$40B in 2025 with 3,500 employees, a ~2x from the year before. At ~65-70% profit margin, that's $8M profit / employee, the highest for a 1000+ ppl company. High-frequency trading continues to be the most efficient money making engine. I want to share an old story about my Jane Street interview in 2014. Jane Street was known for hiring a lot of math, physics and CS olympiad winners from top universities and putting them through many rounds - including, for trading roles, a gauntlet of mental math. It was my 6th interview and my final round and I recall being asked "What is the next day after today in DD/MM/YYYY where all the digits are unique?" They'd toy with you and say "You can use a pencil and paper, if you want" but you knew that was an instant no. Painstakingly and as quickly as I could, I came to an answer. "How confident are you that this is correct on a 0-1 probability scale?" the interviewer said. "0.95", I blurted out, not fully knowing how to answer that. "Are you sure?" After thinking harder for a few more seconds, I realized I could've flipped the digits around to get a closer date. I gave the interviewer my answer. It was correct. "0.95 huh?" he chuckled. That's when I knew I failed. Note: fwiw, other companies that come close in efficiency are - Tether ($90M+ profit/emp) - Hyperliquid ($80M+ profit/emp) and on revenue: - Valve ($50M/emp) - OnlyFans ($37M/emp) - Craigslist ($14M/emp) - Anthropic ($12M/emp, run rate) - OpenAI ($8M/emp, run rate) For comparison, Nvidia is very efficient at scale and is $4.4M/emp.

What is the biggest scam??

And two days from now on FB 😂

No hate, but why doesn’t India’s own AI have its own login system? Why be dependent on Google or Microsoft for login?

The US right now has technology similar to what is said about Pushpaka Vimana. That is, a large object the size of a car can simply hover in the air forever without any rotor, aerodynamic, or engine based thrust (like helicopters, planes, and rockets respectively). In the next decade, the world will be in awe as such technology is slowly revealed. Of course, with a UFO/Aliens hype in media for max psyops to have plausible deniability, yet confuse and scare the adversary. Don't mock me for this post. I know what I'm talking about. Also know that some physics and maths we learn are redacted versions of extended knowledge some select institutions and few humans in them possess. Which means if you have been programmed that Bitcoin is built on unbreakable encryption based on amazing math, you are being misled. It will be broken when it needs to be in an instant by the same who developed it and made the world adopt it. Until then enjoy the party.
