Technically they're raising at $18.2B or $18.4B in the typical sense of the word "valuation" since the 17 is pre-money. Also, as an investor in such a late round, there are likely multiple provisions for getting your money back such that while a large investment, it may not be particularly risky. Even if Uber crashes and burns and gets acquired for only $3B, investors in this round probably still double their money.
