William Blair's recent upgrade on Tesla (NASDAQ: TSLA) zeroes in on the company's pivot from pure automaker to an AI‑driven mobility platform, anchored by its nascent robotaxi business. Here's a data‑backed breakdown of their thesis, valuation model, and risk factors—plus exactly how to tap Financial Modeling Prep APIs to power your own analysis.

Why William Blair Is Bullish on Robotaxis

• Trillion‑Dollar TAM: The firm pegs the robotaxi market at $1.4 trillion by 2040, assuming ride‑hailing hits 1.1 trillion miles annually.

• Competitive Edge: Tesla's vertical integration and cost structure could enable near‑60% EBITDA margins at half the per‑mile price of rivals.

• Market Share Forecast: A 35% slice for Tesla versus 15% for Waymo and 38% for Uber.

“We believe the launch of robotaxi keeps momentum at Tesla's back,” William Blair concludes.

Breaking Down the Valuation Model

William Blair's sum‑of‑the‑parts analysis assigns TSLA:

• $298.61/share to robotaxi

• $30.73/share to energy

• $28.09/share to auto

• → Fair value: $357.43

Valuation in Context

• Forward P/E Check: Use the Ratios TTM API to pull TSLA's latest P/E, P/B, and EV/EBITDA.

• DCF Scenario Modeling: Stress‑test the robotaxi thesis by plugging 60% EBITDA margins into the Advanced DCF API to compare fair‑value outputs under different growth and cost assumptions.

Key Risks to Watch

1. Delivery Headwinds: Q2 deliveries revised down to ~355,000 units vs. consensus 385,000.

2. Model 2 Cancellation: Gaps in the entry‑level lineup may cap volume growth.

3. Regulatory & Tariffs: Foreign entity restrictions on battery materials and U.S. EV tax credit phase‑out.

4. Competition Heat: New entrants from Xiaomi and legacy OEMs ramping EV and LIDAR‑based offerings.

Actionable Takeaway

William Blair's robotaxi bullishness hinges on execution risk—both in scaling autonomy safely and navigating macro headwinds. By combining real‑time multiples from the Ratios TTM API with long‑term DCF outputs, you can build a dynamic valuation dashboard that updates with every earnings release and robotaxi rollout milestone.
