The move towards ~$400 for Tesla Inc. is less about a single feature and more about whether the market believes FSD is transitioning from promise to monetisable platform.

1. Will subscription data satisfy?

FSD Streaks is clever. It targets engagement, which is the leading indicator of subscription stickiness. What the market will look for:

Net FSD subscriber growth, not just uptake

Retention / churn improvement (this is key)

ARPU stability or expansion

If Tesla shows rising engagement translating into recurring revenue, it strengthens the “software multiple” narrative. If not, the feature risks being seen as cosmetic.

2. What matters more than earnings headline

FSD revenue trajectory and attach rate

Commentary on autonomy timelines (robotaxi credibility)

Margin impact from software vs hardware compression

3. Path to $400

Bull case: Strong FSD metrics + confident guidance → breakout above $400, momentum chase likely

Base case: Mixed data → rejection near $400, consolidation

Bear case: Weak subs / vague autonomy roadmap → sharp pullback (crowded positioning risk)

Bottom line

$400 is not just technical resistance. It is a credibility test. Earnings will only break it if Tesla proves FSD is becoming a repeatable, scalable revenue engine, not just a feature users experiment with.
