Sub-questions (Fermi decomposition)

What were the Carbon Arc Gemini App Downloads values for the most recent months (June, July, August 2026), and in what unit is the 250 threshold denominated?
What is the month-over-month growth trend in Gemini downloads over the past 6-12 months, and what does a simple trend extrapolation imply for September 2026?
Were there major Google catalysts in September 2026 (new Gemini model release, viral feature like Nano Banana in 2025, Pixel launch, iOS/Android default assistant changes, marketing pushes) likely to spike downloads?
How does September historically compare to August for Gemini and comparable AI assistant apps (ChatGPT, Claude) in download volume (seasonality, back-to-school, iPhone launch)?
What do third-party estimators (Sensor Tower, Appfigures, Similarweb) report for Gemini app downloads in September 2026, and how do their figures typically map to Carbon Arc's numbers?
How have prior KXGEMINIAPP monthly markets resolved relative to their strike ladders, and what distribution do the other September 2026 strikes currently imply?

Planner reasoning

This is a numeric data-release market resolving on Carbon Arc's Gemini App Downloads figure for September 2026 versus a 250 threshold, so the key work is establishing the unit and recent monthly values from Carbon Arc (and related Kalshi strikes in the KXGEMINIAPP series), the month-over-month trend, September seasonality for AI apps, and any Google launch catalysts (new Gemini model, Pixel/iOS cycle, viral features) in September 2026. The Kalshi price is the primary anchor, and sibling strikes in the same series give an implied distribution to check against a trend extrapolation.

3. Evidence Brief Sonnet 5 · 6316 chars

# Event Will Carbon Arc's "Gemini App Downloads (September 2026)" figure be above 250? # Outcomes to forecast - Yes (Sep 2026 downloads > 250 [unit unconfirmed, likely millions]) - No (≤ 250) # Kalshi market anchor **Current YES price: 9%** (KXGEMINIAPP-26OCT08-T250). 7-day change +1pt; 30-day change **-13pts** (was ~22% a month ago, now 9% — market has become materially more bearish on YES). Price range over 15 days: 1%–22%. Avg daily volume 678 contracts — moderately liquid. This 9% is the number to beat. # Resolution source Tool only reached Carbon Arc's generic homepage ("Infrastructure for the AI Economy") — no dashboard, dataset, or numeric figures were retrievable. Cannot confirm current data, unit definition, or whether any prior months' values are already public. Status: unresolved/unknown from primary source. # Sub-question answers 1. **Recent months' values/unit** — Not found in primary Carbon Arc source. Third-party proxy (Appfigures via claude_news): Gemini downloads were 35.7M (Dec 2025) declining to 27M (Feb 2026) — a downward trend in tens-of-millions range, not confirmed to match Carbon Arc's unit or scale. 2. **MoM trend / extrapolation** — No reliable Carbon Arc series obtained. The code_execution tool explicitly had **no live internet access** and fabricated an illustrative 58M→188M series, producing implausible "100% probability" outputs — this should be **discounted entirely** as non-evidentiary. Actual third-party data (Appfigures) shows decline, not exponential growth, in early 2026. 3. **September 2026 catalysts** — Multiple real catalysts land inside the resolution month: Google Assistant shutdown on Android/Wear OS (2026-09-04, forcing user migration to Gemini — confirmed via multiple outlets), Gemini app launch for Windows (2026-09-11, confirmed via Google blog + press), and residual momentum from Pixel 11 launch (2026-08-12) putting Gemini at the center of the phone's AI. Google also announced Gemini hit 950M MAU (2026-07-22) and passed 1B MAU (2026-08-11-13) — user-base growth is real and rapid, though MAU ≠ downloads. 4. **September vs August seasonality** — No specific comparative data found for Gemini or ChatGPT/Claude download seasonality this cycle. 5. **Third-party estimator figures for Sep 2026** — None found directly; most recent hard figures are Appfigures Dec 2025 (35.7M) and Feb 2026 (27M), both far below a 250 (million) threshold if that's the unit. No September 2026 estimate surfaced. 6. **Prior KXGEMINIAPP resolutions / strike ladder** — No historical resolution data found; other September strikes not surfaced in this research (kalshi_related returned no on-series matches, only unrelated tickers). # Key facts (high-confidence, factual) 1. [kalshi_direct] YES currently priced at 9%, down from ~22% a month ago. 2. [CNBC 2026-07-22] Gemini app had 950M MAU as of Q2 2026 earnings, daily actives tripling YoY. 3. [Forbes/SEJ/Gizmodo, 2026-08-11/12] Gemini passed 1B MAU in August 2026, called Google's fastest-growing consumer product ever. 4. [PCMag/Toms Guide/HowToGeek, 2026-08-05/06] Google Assistant shut down on Android/Wear OS on 2026-09-04, redirecting users to Gemini. 5. [Google blog/TechRadar/Droid-Life, 2026-09-11] Gemini app launched for Windows. 6. [getpanto.ai via claude_news] Appfigures: Gemini downloads 35.7M (Dec 2025) → 27M (Feb 2026), a declining trend. 7. [claude_news, 2025 precedent] Nano Banana viral feature drove Sept 2025 downloads to 12.6M (Appfigures), up 45% MoM from 8.7M in Aug 2025 — illustrates catalyst-driven spikes, but at a scale (~10M) far below 250. # Cross-market signals - Kalshi related: No same-series comparables surfaced (KXGEMINIAPP series returned 0 usable markets); keyword search returned irrelevant markets (FDA approvals, World Cup goals). - Polymarket: "Gemini 4.0 released by Sep 30, 2026" priced at only 6.5% Yes — suggesting market does NOT expect a major new-model catalyst within September, reducing likelihood of a Nano-Banana-style download spike. "Google Gemini #3 Free App on Sep 18" priced at 27% — modest chart strength, not a chart-topping surge. - Sportsbook: N/A. # Analyst opinions and speculation - claude_news synthesis flags the 250 threshold as likely referring to millions of monthly downloads, which would be a "massive outlier" versus the 27–36M range seen in early 2026, requiring an unprecedented catalyst. - Same source notes unit ambiguity could materially change the conclusion; Carbon Arc's actual dataset/definition wasn't accessible. - The fabricated code_execution "trend model" is not trustworthy (no real data), but its own output flags a huge gap between naive trend extrapolation and an "illustrative" market price, suggesting genuine market pricing already reflects skepticism about extreme download growth. # Directional lean per outcome - **Yes (>250):** Real catalysts exist in Sept 2026 (Assistant shutdown forcing migration, Windows app launch, Pixel 11 halo, 1B MAU momentum) that could plausibly spike downloads/installs. But best available proxy data (Appfigures, tens-of-millions range, declining Dec–Feb) argues strongly against reaching 250 (if millions). Polymarket shows no major new-model catalyst (Gemini 4.0) expected in Sept, reducing viral-spike odds. - **No (≤250):** Supported by declining Appfigures trend, absence of a confirmed Nano-Banana-scale viral catalyst, Kalshi's own 30-day price decline (22%→9%) indicating the market has grown more confident in No, and historical download levels (even 2025's viral peak was ~12.6M) being far below 250 if unit is millions. # Gaps / unknowns - Unit definition of "250" is unconfirmed (millions? index score? different metric) — critical uncertainty. - No verified Carbon Arc historical monthly series (Jun–Aug 2026) obtained. - No confirmation of how prior Gemini/ChatGPT Kalshi app-download markets resolved. - Magnitude of the Assistant-shutdown-driven migration effect on Gemini downloads specifically is unquantified. # Calibration anchors - Kalshi current YES price: **9%** (primary anchor; declining trend over 30 days). - Precedent: Sept 2025 Nano Banana catalyst drove Gemini downloads to ~12.6M (45% MoM spike) — even a strong viral catalyst historically produced downloads far below a 250 (million) bar, supporting market's low-probability pricing.

4. Forecasters 5 draws · Fable 5.1 + GPT-5.6 Sol

claude-fable-5-1

36% conf

Yes	9%
No	91%

The Kalshi anchor sits at 9% YES and has fallen from ~22% over the past month, indicating participants with access to Carbon Arc's series have grown more confident the September figure lands at or below 250. Third-party proxy data (Appfigures: 27–36M monthly downloads in Dec 2025–Feb 2026, declining) argues strongly against a >250 result if the unit is millions, and even the Nano Banana viral spike in Sept 2025 only reached ~12.6M. Real September catalysts (Assistant shutdown on Sep 4, Windows app launch Sep 11, 1B MAU momentum) create some upside tail, but Polymarket pricing Gemini 4.0 by Sep 30 at only 6.5% suggests no major new-model spike is expected. Given unconfirmed unit definition and no access to the Carbon Arc series, I stay essentially at the market anchor.

claude-fable-5-1

40% conf

Yes	9%
No	91%

Kalshi prices YES at 9%, down from ~22% a month ago, signaling traders with likely visibility into the Carbon Arc series have grown more confident in No. The best third-party proxy (Appfigures) shows Gemini downloads at 27–36M/month in early 2026 and declining, an order of magnitude below a 250 (million) bar; even the viral Nano Banana spike in Sept 2025 only reached ~12.6M. September 2026 catalysts (Assistant shutdown, Windows app, Pixel 11 halo) are real but unlikely to produce a ~7–9x jump, and Polymarket's 6.5% on a Gemini 4.0 release removes the main viral-model catalyst. The key residual risk is unit ambiguity in Carbon Arc's metric, which keeps me from going below the market anchor.

claude-fable-5-1

45% conf

Yes	9%
No	91%

Kalshi prices YES at 9%, down from ~22% a month ago, indicating the market has grown more confident that the 250 threshold is a tail strike. Third-party proxy data (Appfigures: 35.7M Dec 2025 → 27M Feb 2026, and even the viral Nano Banana peak at ~12.6M in Sep 2025) sits far below 250 if the unit is millions, and Polymarket's 6.5% on a Gemini 4.0 release by Sep 30 suggests no major viral catalyst is expected. Real September catalysts (Assistant shutdown migration, Windows app launch, Pixel 11 halo, 1B MAU) support some upside tail, but MAU growth does not translate to a ~7-10x download spike. The unconfirmed unit definition of Carbon Arc's figure is the main reason not to move well below the market anchor, so I stay essentially at 9%.

gpt-5.6-sol

58% conf

Yes	8%
No	92%

The 9% Kalshi YES price is the primary anchor, and its decline from roughly 22% indicates increasingly bearish market information. Available Appfigures proxies place monthly downloads in the tens of millions and declining, making 250 million an extreme outlier, while no direct September estimate or favorable seasonality evidence was found. September's Assistant migration, Windows launch, Pixel 11 halo, and billion-user momentum provide upside, but the low probability of Gemini 4.0 and historically much smaller catalyst-driven spikes argue against crossing the threshold. I move slightly below the market to 8%, while retaining meaningful tail risk because Carbon Arc's unit and historical series remain unverified.

gpt-5.6-sol

58% conf

Yes	8%
No	92%

The 9% Kalshi YES price is the primary anchor, and its decline from roughly 22% indicates increasingly bearish market information. Available Appfigures proxies place downloads around 27–36M, while even the September 2025 viral spike reached only 12.6M, pointing strongly toward No if the 250 threshold means millions. September catalysts such as the Assistant migration, Windows launch, Pixel 11, and 1B MAU create some upside, but no major new-model release is expected and MAU does not directly imply downloads. I move slightly below the market to 8% because the scale gap is enormous, while retaining meaningful tail risk due to the inaccessible Carbon Arc series and unresolved unit definition.

6. Final plain mean of 5 draws

9% (47% confidence)

Yes: 9% No: 91%

Mean of 5 draws (0.09, 0.09, 0.09, 0.08, 0.08). The Kalshi anchor sits at 9% YES and has fallen from ~22% over the past month, indicating participants with access to Carbon Arc's series have grown more confident the September figure lands at or below 250. Third-party proxy data (Appfigures: 27–36M monthly downloads in Dec 2025–Feb 2026, declining) argues strongly against a >250 result if the unit is millions, and even the Nano Banana viral spike in Sept 2025 only reached ~12.6M. Real September catalysts (Assistant shutdown on Sep 4, Windows app launch Sep 11, 1B MAU momentum) create some upside tail, but Polymarket pricing Gemini 4.0 by Sep 30 at only 6.5% suggests no major new-model spike is expected. Given unconfirmed unit definition and no access to the Carbon Arc series, I stay essentially at the market anchor.
