🇺🇸🇨🇳 Trump just confirmed that Nvidia CEO Jensen Huang is traveling with him to China aboard Air Force One. He also blasted CNBC as “FAKE NEWS” for reporting that Huang wasn’t invited to the trip. The funniest part is that Trump basically said Jensen is already on the plane and “unless I ask him to leave,” the report is false.





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.



Solar met 75% of global electricity demand growth in 2025. Clean power covered all new demand, so fossil generation didn’t rise for the first time since 2020. Solar electricity is on track to become by far the biggest source of power.




[Update] - Grafik 4 Jam sudah konfirmasi awal akan naik dg target 4857-4861 - Kemungkinan besar Emas akan naik dulu lalu lanjut turun lagi - Namun jika ternyata kenaikannya sampai diatas 4957 pada penutupan akhir minggu maka roadmap turun ke 3925 & 2818 bisa dipastikan gagal
