Ride-hail company Lyft is raising up to $500 million in additional funding, according to a share authorization document filed yesterday in Delaware. This comes one month after Lyft announced a $1 billion infusion led by CapitalG, an investment arm of Google parent Alphabet. A company spokesman stresses that the $500 million is not yet closed, but adds: "Increasing the potential for this round will allow us to further accelerate our commitment to serving passengers and drivers." Details: The new investment would be an extension of the CapitalG-led round, at the same share price of $39.75.
