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, 2027.

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

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

• Production announced for ≥1 GWh/year run rate and confirmed by independent reporting

NO if:

• Only pilot or demonstration scale production exists (<1 GWh/year annualized)

• Sulfide-based SSBs (QuantumScape, Solid Power) are at commercial scale but not LLZO

• Production is announced but not yet physically operating as of Dec 31, 2027

• Limited demo vehicles with LLZO cells but not commercial scale production
