Nvidia-backed cloud company Lambda is reportedly seeking to raise about $4 billion in its final funding round ahead of a planned initial public offering (IPO), according to a report by The Wall Street Journal. The fundraising is described as a pre-IPO step intended to position the company for public markets.

The two outlets provided here both reference the same WSJ report and frame the effort as a major capital-raising push before an IPO. The coverage emphasizes Lambda’s backing by Nvidia and the scale of the targeted funding, but does not provide additional, outlet-specific details such as the exact valuation, investor list, pricing, or timing of the IPO in the material supplied. Without more information from other sources, the precise terms of the round and the company’s stated IPO timetable remain unclear.

Overall, the agreed focus across the provided materials is that Lambda is raising approximately $4 billion prior to a planned IPO and that Nvidia support is a central part of its positioning.
