If we're predicting upcoming bailouts from this crash, I would bet on U.S. oil companies and everything big in China. China could potentially cause a massive earthquake in international trade.
The student-loan bubble is also a massive debt overhang that could cause huge repercussions, but I don't see a trigger that would cause it to burst.

(It's also less than Alphabet, given stock price movements since August. Take Uber and Xiaomi out of the unicorn list and the aggregate value of all unicorns combined is a little less than Microsoft.)
The total value of unicorns, including Uber and Xiaomi, is roughly 10% of the NASDAQ 100. [per same link]
The total value of the NASDAQ 100 is about 1/4 that of the S&P 500:

Multiply them out and all unicorns together are worth about 2-3% of the S&P 500, or less than 1/4 of the decline since the beginning of the year. That's the typical fluctuation in value on a fairly active trading day.
I don't think this is how it works. The problem is there is too much speculative capital floating around; it creates bubbles anywhere some rich dudes smell opportunity. It does not have to be a jackpot; any hope of a fat percentage will bring the money around.
i think this is correct but incomplete. in the modern global financial system there can be very long-range correlations between investors in both the short term and the long term. if those private investors' performance is highly coupled with the health of large financial institutions it could destabilize everything.
when all the debt and credit in the world is structured and restructured into more and more complex financial products local risk can easily become systemic.
Especially, since people can't default on them.
So the hangover will stay with us for as long as people who took student loans are alive. (Or perhaps even manage to pay them off.)
