# The Robotaxi Overhaul: Uber and Rivian Forge a New Mobility Alliance

The U.S. electric vehicle and mobility sector is undergoing a massive structural overhaul. I'm told that the intensifying race for autonomous commercialization is forcing automakers and ride-sharing platforms into unprecedented alliances. Leading the charge in 2026 is the budding ecosystem between mobility giant Uber and EV disruptor Rivian, a partnership poised to fundamentally rewire urban transit networks.

### Rivian Automotive (RIVN.US)

Rivian Automotive (RIVN.US) is navigating a remarkably busy summer. According to people familiar with the matter, the company successfully closed a **75 million-share** offering in early July, raising **USD 1.16B** to support project investments tied to a Department of Energy loan agreement. On the operational side, the EV maker produced over **12,600** vehicles in Q2 2026, prompting management to raise its full-year delivery guidance to up to **70,000** units.

Financially, Rivian expects Q2 revenue to land between **USD 1.55B** and **USD 1.65B**, backed by a healthy liquidity buffer of roughly **USD 5.3B**. Yet, the real game-changer lies in its autonomous aspirations. Following the commencement of public deliveries for its R2 SUV, Rivian has cemented a pact with Uber to deploy up to **50,000** autonomous robotaxis based on the R2 platform. I'm told the initial roll-out is targeted for Miami and San Francisco by 2028.

### Uber Technologies (UBER.US)

Uber Technologies (UBER.US) is aggressively transforming its core business model to expand its local commerce and autonomous mobility footprint. I've learned that the platform made a huge splash in July 2026 by striking a **USD 14.8B** deal to acquire German delivery giant Delivery Hero. Once closed in late 2027, this acquisition will catapult Uber's presence to **99** markets globally, significantly beefing up its dual-service ecosystem.

Beyond logistics—where Uber Eats recently branched into electronics through a tie-up with GameStop—the company's endgame clearly revolves around a self-driving fleet. Internal momentum suggests Uber is entirely serious about its autonomous pivot. Alongside a potential **USD 1.25B** investment into Rivian to fuel their joint robotaxi venture, Uber is quietly assembling a vast global autonomous network, plotting commercial robotaxi deployments with partners like Lucid and WeRide across major global cities.
