This market resolves YES if at least one automotive OEM or battery manufacturer is producing LLZO (Li7La3Zr2O12, lithium lanthanum zirconium oxide) solid-state battery packs at commercial scale — defined as an annualized production rate of at least 1 GWh/year at a single facility — by December 31, 2029.

YES if:

• Toyota, Samsung SDI, or another OEM has confirmed commercial LLZO SSB production at a single facility with annualized capacity of at least 1 GWh/year by Dec 31, 2029

• Commercial vehicle deliveries with LLZO SSB packs are documented (not prototype/demo)

• Production at ≥1 GWh/year run rate confirmed by company disclosures or independent audit

NO if:

• Only pilot or demonstration scale production exists (<1 GWh/year annualized) by Dec 31, 2029

• Only sulfide-based SSBs (not LLZO garnet chemistry) reach commercial scale

• LLZO production is announced for future dates beyond Dec 31, 2029
