Uber said “multi-hundred-million” and meant something closer to half a billion. The ride-hailing company’s commitment to self-driving start-up Nuro is near $500m, according to sources directly aware of the matter, a figure that reframes a partnership Uber had described in vaguer terms and reveals a follow-on investment significantly larger than its first.

The new detail is the size and the structure, not the existence of the deal. Uber had already disclosed that it took part in a $203m funding round for Nuro that valued the start-up at $6bn, and that it planned a multi-hundred-million-dollar investment.

What the sources add is an unreported follow-on that pushes the total commitment to roughly $500m, with additional funding agreed to unlock once Nuro hits certain development and commercial milestones. Those terms were not disclosed.

The money buys Uber a particular kind of supplier relationship. Nuro builds the autonomous driving system; Uber wants the rides. The clearest expression of that is a three-way arrangement with Nuro and electric-vehicle maker Lucid to put 35,000 robotaxis on the road using Lucid’s Gravity SUVs and forthcoming midsize vehicles.

The investment in Nuro is the autonomy layer of a fleet Uber is assembling through deals rather than building itself.The 💜 of EU techThe latest rumblings from the EU tech scene, a story from our wise ol' founder Boris, and some questionable AI art. It's free, every week, in your inbox. Sign up now!
