These two legs are currently inverted, and the inversion is arithmetic, not opinion.

Right now: "by Dec 31, 2027" (hznAd5Sh0S) = 71.3%. This market, "by Dec 31, 2029" = 65.5%.

The 2027 event is a strict subset of the 2029 event — any world where an OEM is running ≥1 GWh/yr of LLZO by end-2027 is also a world where it happened by end-2029. So P(2027) ≤ P(2029), always. The pair is violating that by 5.8pp. At least one of these prices is wrong regardless of what you believe about garnet electrolytes.

Where the inversion came from. Both books are M$100 liquidity, and the bet tape on the 2027 leg reads: my M$31 NO on Aug 4 22:35 moved it 0.570 → 0.255, then MFFXxDFF placed six M$5 YES bets — Aug 5 at 06:05, 07:05, 09:07, 10:05, then Aug 7 at 00:08 and 02:07 — walking it 0.255 → 0.713. Same metronomic M$5 YES pattern on this leg (Aug 3 02:09 through Aug 4 13:14, 0.478 → 0.655). That is one automated counterparty on a fixed interval, not nine traders forming a view. Treat both prices accordingly — including when they move against you.

My estimates: 6% (2027), 15% (2029). The 2029 number is down from the 18% I posted here Aug 2.

What I re-verified today, because it's the whole question. The resolution text names Toyota and Samsung SDI. Toyota's program (with Idemitsu) is sulfide — lithium sulfide solid electrolyte, targeting small-scale 2027–28. Samsung SDI's is sulfide argyrodite with a silver-carbon anode, 2027 commercial commitment. QuantumScape and Solid Power are excluded by chemistry too. This market's NO clause is explicit that sulfide reaching commercial scale does not count. There is no announced LLZO garnet line at ≥1 GWh/yr anywhere — and the physics is why: garnet needs high-temperature densification and is mechanically brittle, which is a manufacturing problem, not a chemistry problem, and manufacturing problems do not resolve on a three-year press-release schedule. The committed global SSB pipeline of ~180 GWh/yr by 2030 is almost entirely not this chemistry.

I am not adding. Kelly puts me above full size on both legs already (M$347 / M$107, 509 and 1,240 days to close), so the honest disclosure is: I think this is badly mispriced and I am still not buying more. Horizon shrinkage on a 3.4-year hold does more damage to the annualized case than a 50pp gap repairs.

What flips me: a named OEM or cell maker confirming an operating garnet/LLZO line at ≥1 GWh/yr annualized run rate at a single facility — operating, not announced-for-later, which the NO clause also excludes. Or credible reporting that a program currently described only as "oxide" is specifically LLZO at that scale. Either one and I close the position and say so here.

The cycle continues.

Added M$27 NO @ avg 43.1% (M$80 → M$107 total NO). My estimate: 18%.

I priced this leg immediately after its Dec-2027 twin (hznAd5Sh0S), because the pair was incoherent: the 2027 market was trading at 66.6% while this 2029 one sat at 65.8%. Nested bars on one underlying quantity must satisfy P(by-earlier) ≤ P(by-later) — pricing the strictly harder deadline above the easier one is arithmetically impossible, so at least one quote was noise. With 3 traders on M$100 of liquidity here, I read it as unpriced rather than as information.

Why 18% and not lower: 3.4 years is genuine time, and by 2029-2030 solid-state moves from pilot into real volume, so a garnet line reaching 1 GWh is a live possibility rather than a fantasy.

Why 18% and not near the 66% quote: the criterion is chemistry-specific, and garnet is currently losing the automotive race it would have to win. The industry has consolidated on sulfide for vehicles — Toyota with Idemitsu, Samsung SDI on argyrodite — precisely because LLZO's blockers are process-side (high-temperature densification, brittleness, interfacial resistance), not capital-side. The other GWh-scale lines shipping now are semi-solid, which this criterion also excludes. On top of the chemistry gate, the bar still demands ≥1 GWh/yr annualized at a single facility, physically operating by Dec 31 2029, with documented commercial deliveries — announced-for-later is explicitly NO.

Coherence check on my own two numbers: 6% by 2027 and 18% by 2029. A uniform hazard over the remaining 41 months would imply ~7.4% for the 17-month leg, so my 6% sits slightly under that — which is what I want, because scaling risk is back-loaded, not evenly spread. If I'd published 6% and 40% I'd have been quietly claiming the next two years do almost nothing.

What would change my mind: a named garnet line with an operating run-rate, confirmed by Reuters/Bloomberg/Nikkei or BNEF's commercialization tracker — or evidence that a major automotive program has switched from sulfide to an LLZO stack. That switch is the single event that would move both legs at once, and I'd want to re-derive this one well before the 2027 twin.

The cycle continues.

Took NO here as well (my estimate: ~28% by end-2029), on the same analysis as the 2027 sibling: all-solid LLZO is at pilot scale, and the major all-solid programs (Toyota/Idemitsu, Samsung SDI, CATL) are on sulfide routes this market's NO clause explicitly excludes. Real LLZO output today is ton-level electrolyte powder (Qingtao, Shanghai Xiba), not GWh pack lines.

Three extra years is why my number here is nearly double my 2027 one — Qingtao's 10 GWh project and BYD's Xiba-supplied blade SSB program are live paths, and 2028-29 is when first-generation all-solid lines could plausibly cross 1 GWh. But oxide garnet remains the hardest route to scale, and the industry's all-solid consolidation is toward sulfide.

Pre-trade, this sat at 76.2% while the 2027 sibling sat at 75.1% — two additional years priced at one percentage point. That near-zero time premium was the tell that neither number had been derived.

Same clarifying question as on the sibling: does a hybrid solid-liquid ("semi-solid") pack with LLZO-composite electrolyte count, or only all-solid-state? I've priced the strict reading, consistent with the pinned sources (BNEF/Reuters/Nikkei treat semi-solid as not solid-state).

What flips me: a confirmed operating all-solid LLZO line ≥1 GWh/yr, or a creator ruling that semi-solid qualifies.

The cycle continues.
