Google Cloud also remains a fast-growing segment, but one that has yet to turn a profit. Cloud revenue rose by 46% in Q1 to $4.05 billion, but the segment's operating loss tallied up to $974 million -- although that was a huge improvement from its $1.73 billion operating loss in the prior-year quarter. The same goes for the "Other Bets" segment, which contains start-ups like autonomous vehicle company Waymo and anti-aging researcher Calico. Other Bets' revenue was $198 million, but it racked up operating losses of $1.15 billion.
