REX Shares and BMO are rolling out a new way to make leveraged bets on the AI economy. The MicroSectors 3x Long MANGOS+ ex Private Companies ETN, trading under ticker MNGU, begins trading on NYSE Arca on August 27, 2026.
The product delivers 3x daily leveraged exposure to the NYSE MaNGoS+ Index, an equally weighted basket of ten publicly traded US companies deeply embedded in the artificial intelligence supply chain.
What’s in the basket, and what’s not
The “ex Private Companies” part of the name is doing real work. The MaNGoS+ Index deliberately excludes Anthropic and OpenAI, two of the most prominent AI companies on the planet, for one simple reason: you can’t buy their shares on a public exchange.
As of August 25, 2026, the estimated index weights included Palantir at roughly 13.1%, Microsoft at 12.8%, NVIDIA at 10.3%, Meta Platforms at 9.9%, and SpaceX at 7.7%.
