🚨 BREAKING: Joby Aviation has completed the first point-to-point electric air taxi flights in New York City, connecting JFK to Manhattan heliports in under 10 minutes. The flights are part of a White House-backed pilot program.

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.

Ah man, why would they do this. I really hope they reverse this decision

Both OKX and Binance are regulated by multiple regulators. As the UBO of a regulated company, publicly offering a $1 billion bet is hardly professional conduct. I would be curious whether Binance’s regulators consider that acceptable. As for whether you have misled the public and lie to world, the test is actually simple: has your Binance stake been legally separated with your ex-wife or not? Bill Gates and Jeff Bezos have already shown what proper asset separation looks like in a divorce.
