I'm actually surprised that he didn't win this bet since it wasn't really based on non-bubble metrics in the first place. A more interesting bet to me would have have involved profitability, P/E ratio, or some other long-term indicator that current high-rolling unicorns are actually sustainable businesses. I think WeWork has demonstrated pretty clearly that billions of dollars of VC money can prop up unsustainable companies for more than 5 years (i.e. the market can remain irrational longer than the term of this bet).
