As autonomous vehicles drop the per-mile cost of ride-sharing to under $1, it will become cheaper than owning a car. This price drop will induce massive demand, shifting most transportation to these networks and creating a market exponentially larger than the current industry.

When investing in high-risk, long-development categories like autonomous vehicles, the key signal is undeniable consumer pull. Once Waymo became the preferred choice in San Francisco, it validated the investment thesis despite a decade of development and high costs.

The memo details how investors rationalize enormous funding rounds for pre-product startups. By focusing on a colossal potential outcome (e.g., a $1 trillion valuation) and assuming even a minuscule probability (e.g., 0.1%), the calculated expected value can justify the investment, compelling participation despite the overwhelming odds of failure.

While its technology is advanced, Waymo's most significant competitive advantage is its head start in securing regulatory permits to operate and charge for rides. Competitors like Amazon's Zoox are far behind, not yet able to take paid passengers. This regulatory moat creates a powerful first-mover advantage in lucrative urban markets.

Founders in deep tech and space are moving beyond traditional TAM analysis. They justify high valuations by pitching narratives of creating entirely new markets, like interplanetary humanity or space-based data centers. This shifts the conversation from 'what is the market?' to 'what could the market become?'.

Waymo's potential $100B valuation, over 200 times current revenue, is based on more than its robo-taxi service. Investors are betting on future high-margin revenue streams, particularly licensing its autonomous driving software to established automakers. This B2B model is key to justifying a valuation far beyond traditional transportation multiples.

Companies pursuing revolutionary technologies like autonomous driving (Waymo) or VR (Reality Labs) must endure over a decade of massive capital burn before profitability. This affirms venture capital's core role in funding these long-term, high-risk, high-reward endeavors.

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.

Venture capitalists may value a solid $15M revenue company at zero. Their model is not built on backing good businesses, but on funding 'upside options'—companies with the potential for explosive, outlier growth, even if they are currently unprofitable.
