Despite being founded in Los Angeles, Latham's largest office is now in New York City, with more than 450 lawyers as of February 2021. The firm claims it is the only fully integrated multinational law firm with no single headquarters. In 2007, Latham & Watkins became the first American law firm to attain more than $2 billion in yearly revenue, and in 2015, the firm surpassed the likes of DLA Piper, Baker & McKenzie and Skadden to become the highest-grossing law firm in the world for the first time. Since then, Latham was the first law firm to report surpassing US$3 billion in gross revenue in 2018 but lost the spot as the world's top-grossing law firm that same year to Kirkland & Ellis.
