China is not hedging. It's escaping. (Ad)

China's US Treasury holdings have fallen from a peak of $1.32 trillion to roughly $659 billion, an 18-year low. Beijing's central bank has bought gold for 20 straight months, its longest streak in a decade. Goldman Sachs estimates China's real gold buying is 4.8 times the official figure. The European Central Bank confirms gold has overtaken US Treasuries as the world's top reserve asset, at 27% versus 22%. As foreign demand for US debt fades, rates and everyday costs may feel the pressure.tc pixel

SpaceX is NOT the #1 IPO of 2026 (Ad)

A lesser known AI company is growing faster than both SpaceX and OpenAI. Its coding business reportedly grew from 500 million dollars to 2.5 billion dollars in just five months, and more than 300000 businesses now use its technology. While OpenAI reportedly lost 39 billion dollars last year, this company is projecting a 559 million dollar quarterly profit. Google, Amazon, Nvidia, Microsoft, Sequoia and Peter Thiel's Founders Fund have all reportedly backed it. A publicly traded backdoor may offer regular investors exposure before the expected IPO frenzy, no accredited status or brokerage minimums required.tc pixel
