The four KPIs that actually move the tape
Strip the noise from earnings night and four data points carry the move: (1) Starlink subscriber adds vs consensus, (2) Starlink ARPU print, (3) Starship operational milestones since last quarter, and (4) AI1 capex run-rate vs the $8.5B authorisation. Everything else is colour.
Of those, ARPU has the highest single-print sensitivity. A $2 ARPU beat (vs ~$95 consensus) historically produced 4-6% upside in pre-IPO secondary marks; a miss produced symmetric downside. Sub adds matter more in trend than in single-quarter print.
Position sizing and structures
Implied move for the August print is currently around 7.5%, slightly above the 6-7% range for typical mega-cap prints. That premium reflects (a) a young trading history and (b) ARPU sensitivity. Selling at-the-money straddles is the standard fade if you think the move will be smaller; long out-of-the-money strangles work if you think it will be bigger.
Key takeaways
- Four KPIs carry the print: subs, ARPU, Starship cadence, AI1 capex
- ARPU has the highest single-print sensitivity
- Implied move ~7.5% — premium to mega-cap norm reflects IPO-era IV
