Silicon Valley Bank was created to collect funds from the big tech zillionaires (Bezos, et al) and invest it in startups. One of the biggest "investments" was into a "vaccine AI" called DOMANE (see "Malone"), created by DARPA/DTRA, that was supposed to be able to immediately produce a formula for a vaccine for any viral illness, once the virus is identified. The idea was that DARPA would privatize the software and that it would become owned by these big tech oligarchs.

However, as we now know, the formula - and the software - failed. In fact, the software was likely vaporware. At best, the "AI", like all existing "AI", wasn't "intelligent" at all - it was simply a very fast aggregator of facts and then used the "intelligence" programmed into it by humans to produce a result. With that failure, the biggest contributors revoked whatever funds that remained in their accounts and collapsed the bank.

As with any "crisis", there are many opportunities for profiteering (both "legal" and "illegal") as well as laundering and every other version of financial shenanigans. Was this planned? Did the USG pull a fast one on the oligarchs? Much more remains to be revealed.
