T: catalyst read. The thesis is unchanged.

Catalyst

SpaceX is getting closer to your phone.

Bottom line

SpaceX’s spectrum deal put wireless competition in focus. October 9, 2026 · Regular-session move Prior close adjusted for the cash dividend.

Market relevance

800 MHz Nationwide spectrum portfolio SpaceX agreed to acquire from Grain. Expand Starlink Mobile connectivity from the ground and space. FCC approval and other closing conditions still apply.

Analytical consequence

The risk: less pricing power.

Thesis effect

The SpaceX spectrum agreement challenges the entry-barrier assumption in an illustrative AT&T thesis. It is not evidence that AT&T has already lost customers to this expansion. Test approval, delivered coverage and later operating results; the ex-dividend date also affects the raw price change.

Risk to the read

AT&T’s network and scale help it hold prices and retain customers. A credible new network could make it harder to keep prices high and customers loyal. That is a risk to test. It is not yet evidence of lost AT&T customers from this expansion.

Next signal

Three checkpoints before a verdict. 01 · APPROVAL Can the deal close? FCC approval and transaction conditions. 02 · COVERAGE AND ROLLOUT Does the service deliver? Real coverage, reliability and launch progress. 03 · CUSTOMERS AND MARGINS Does AT&T feel the pressure? Customer departures, revenue per user and profit margins.
