The record claims the Series D round was '$4 billion (Amazon Strategic Investment)' with a valuation of $18.1 billion in 2023-09. However, the source clearly distinguishes between: (1) Amazon's $4 billion investment in late 2023 (paid in two pieces), and (2) the Series D round of $750 million led by Menlo Ventures in February 2024. These are two separate funding events. The $4 billion Amazon investment is not the Series D round. The date is also incorrect—the Series D occurred in February 2024, not September 2023. The valuation of $18.1 billion is confirmed, but it occurred 'by early 2024,' not in September 2023.
