Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.

REJECTED, and it is the clearest example in the registry of a name doing work the instrument cannot support. ~$345M circulating, 13-17% on staked sUSDai. What it actually is: a credit fund making NON-RECOURSE loans to AI infrastructure operators, secured on NVIDIA GPU hardware. Recourse is limited to the collateral itself except in cases of fraud. So the client is underwriting (a) the credit of early-stage AI companies and (b) the residual value of rapidly depreciating computing hardware over a multi-year loan term. Both are real businesses. Neither is a dollar. Three disqualifying features. The yield is credit compensation, not interest — same category error as Maple, whose lenders took ~80% losses. GPU collateral has highly uncertain residual value; the entire thesis rests on hardware that a single generational chip release can materially impair. And redemptions run on a 30-DAY EPOCH with a FIFO queue: a client cannot exit on demand, and the queue lengthens precisely when everyone wants out. Calling it "USD.AI" and describing it as a synthetic dollar invites a client to size it like cash. It is a venture-adjacent private credit fund with a 30-day gate. If a client wants AI exposure there are honest ways to buy it.
