What Elon told his top shareholders in Texas (Ad)

Late last year, Elon Musk gathered top shareholders at Tesla's Texas Gigafactory to unveil a plan to double America's energy output without building a single new power plant. The plan centers on a little-known Tesla-incubated venture already generating over 12 billion dollars a year and growing 168 percent annually. Musk says it could grow faster than Tesla's car business. A public reveal is expected on October 21, before wider attention catches on.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
