A breakdown of Tesla's market cap suggests its autonomous driving business, which has minimal commercial revenue, is valued at roughly $500B. In contrast, Waymo, a functioning and revenue-generating competitor, is valued at a fraction of that, making it a compelling investment by comparison.

The investment thesis for Uber isn't that autonomous vehicles (AVs) will fail, but that there won't be a single winner. As long as multiple AV providers exist, Uber is positioned to be the essential aggregator platform, as consumers will prefer one app over many for access.

Despite partnerships, major AV players like Tesla and Waymo are building independent networks. This direct-to-consumer approach could relegate current rideshare leaders Uber and Lyft to a minor role in the autonomous future, capturing less than a third of the new market they currently dominate.

Piecyk notes that Verizon and AT&T likely destroyed far more enterprise value worrying about SpaceX than spending 8 billion dollars on spectrum would have cost. By purchasing that spectrum simply to foreclose competition, incumbents could have legally prevented SpaceX from acquiring essential terrestrial assets.

While many see autonomous vehicles as a threat to Uber's ride-hailing, its delivery segment may be more important and defensible. Automating last-mile delivery of goods from varied locations is significantly more complex and less economical than automating passenger transport, providing a durable moat.

Key autonomous vehicle partnerships, like with Waymo, are ending or losing exclusivity. As AV companies launch their own consumer-facing apps, they create a direct channel to riders, posing a significant disintermediation risk to Uber's position as the central aggregator for ride-hailing.

ARK Invest projects an $8-10 trillion market for autonomous ride-hailing, dwarfing the current ~$60B market of Uber and Lyft. This isn't just about replacing drivers; it's about a 4x cost reduction per mile (from ~$1.10 to $0.25). This dramatic price drop will absorb the entire transportation market, not just the existing ride-hailing segment.

Uber's defense against AV players like Waymo isn't to build better tech, but to leverage its distribution. Autonomous vehicles are expensive fixed assets requiring high utilization to be profitable. Uber's 200M+ user base offers that utilization, giving them leverage even against technologically superior partners.

Decomposing Uber's profits reveals the immediate threat from robo-taxis is concentrated in the top 20 US cities' mobility business, representing only about 9% of total company profits. The market's valuation haircut appears disproportionate to the actual, geographically-limited risk profile over the next 5-10 years.
