Summary

Flapping Airplanes raised a $1 billion Series A. TechCrunch, timestamped 1:57 PM PDT on October 21, 2026 (20:57 UTC), is the earliest report read here, so the round date is 2026-10-21. TechCrunch says Index and Lux co-led. The Raise Track Update says Index Ventures and Lux Capital led. Both are marked as leads.

Index Ventures' post, published Oct. 21, 2026, says Index is leading the round and writes the amount as "$1B million." The post does not name Lux Capital. The company site says the company has raised a $1 billion Series A and lists Index and Lux Capital among its backers. It does not say who led.

TechCrunch names Sequoia, GV, and Kleiner Perkins as participants in the new round. The issue also names Nvidia. The company site says Google Ventures and lists NVIDIA among additional supporters. This page uses GV for Alphabet's GV and Google Ventures, and Nvidia for NVIDIA. TechCrunch places Nvidia in a sentence about investors in the company, separate from the new-round participants. The issue names Nvidia on this round, so Nvidia is a participant here.

TechCrunch calls a $6 billion valuation reported. The issue says $6 billion post-money. Index's post and the company site do not state a valuation, so none is stored. A $180 million seed described by TechCrunch and the company site is not this round and is not stored as a total.

TechCrunch names Valor, Atreides, and A* as investors in the company. The company site names additional firms and people, including Nova Global. Those names are not in the issue and do not have pages.
