# Optimal renewal defaults depend on competitive position, not just industry norms

**Claim:** Incumbents and challengers within the *exact same industry* should often use **opposite renewal defaults**.

**Evidence & logic:** A dominant firm (e.g., **>50% market share** — like [[entity-netflix-d8|Netflix]] or [[entity-chatgpt|ChatGPT]]) should prioritize retention and use **auto-renewal** to defend its installed base. A challenger (e.g., **<20% market share**) must prioritize acquisition and use **auto-cancellation** to lower the barrier for the incumbent's customers to try their product. Copying the incumbent's policy is a critical strategic error ([[contrarian-challengers-should-not-copy]], [[quote-copying-incumbent-error]]). Operationalized via [[action-assess-competitive-position]] and the [[framework-renewal-strategy-matrix]]. See the historical case of [[entity-mci|MCI vs. AT&T]].

**Confidence:** High. **Testable:** Partially (competitive dynamics are hard to run as a clean field experiment).

**Enrichment / validation:** This is a *strategy extrapolation*, not a directly tested result — the field experiment is single-firm (a newspaper) and does not test incumbent-vs-challenger behavior. It aligns strongly with standard competitive-strategy frameworks (incumbents defend base; challengers lower trial barriers) and the documented MCI case.
