$36 million a day says something big is coming (Ad) Institutional capital is flowing into one thesis at a rate of $36 million per day - $25,000 every single minute. Morgan Stanley puts the addressable market at $5 trillion, and the smart money is already positioned. Pentagon-funded research from Rensselaer Polytechnic Institute identified a precise tipping point: once roughly 10% of a population adopts a new idea, the rest of the system flips fast. That threshold was just crossed. Porter Stansberry, with nearly 30 years in the markets, says this opportunity is bigger than dot-com, crypto, and the 2023 AI rally combined.

One hidden supplier shipped 5 billion parts to SpaceX (Ad) Most investors are focused on the historic $1.75 trillion SpaceX IPO expected around June 30. But there's a lesser-known angle that could matter more to your portfolio. One under-the-radar tech firm has already shipped 5 billion critical components to SpaceX - making it a linchpin of the operation. Because SpaceX has been private, this partnership has gone almost entirely unnoticed by Wall Street. Get the name of this overlooked SpaceX supplier before the June 30 deadline
