You can watch the full details in the interview linked on this page. What we do know for sure of what it is not: it isn't a stock investment with Amazon as they have never issued a dividend, which is part of the pitch: that you will be paid dividends. It isn't being an affiliate of Amazon, getting a piece of all sales referred to Amazon via a special link identifying YOU as the lead source. This isn't possible for the same reasons as commissions are not the same as dividend payments. From what we can gather, this is an investment into the warehouse space that Amazon leases, which is an investment called a REIT (Real Estate Investment Trust). This makes the most logical path with Brad Thomas specializing in REITs. This would mean that as Amazon expands, and adds warehouses, the fees Amazon pays for the usage of these warehouses, would be paid a dividend as an investor.
