Short Answer

BP's September 2026 credit card spend is expected to exceed 105.5, propelled by record gasoline prices and resilient U.S. consumer spending; the market prices this outcome at 99%.

1. Market Behavior & Drivers

No specific news or data release coincides with the significant price movements in this market, including the 14 percentage point drop on September 24. Likewise, the materials do not contain a direct catalyst for the sharp repricing from a 4% probability on September 28 to 94% by October 5. The market's overall trajectory has been sharply upward since late September.
As of October 5, the market implies a 94% probability that September credit card spend, measured by Carbon Arc's third-party data panel, will finish above the 98 index level. This reading is supported by significant trading volume, with 2,515 contracts changing hands at that level. This market-implied probability conflicts with other data from the same day showing a 41% chance for the same outcome. The contract is scheduled to settle on October 7 based on the Carbon Arc index, not on BP's own financial reporting.
  • Since last update (~21d): The model's probability for spend Above 105.5 rose +22.5pp, flipping the edge as the model led.
  • Market-led movement saw Above 111.5 probability rise +94.0pp, compressing the edge significantly.
  • Headline model probability surged +11.3pp while the market gained +5.0pp, widening the overall edge.
  • Spend index above 107.5 is likely given record September 2026 gasoline prices.
  • Spend index above 111.5 appears supported by resilient September 2026 consumer spending.
  • Thresholds above 114 have elevated probability due to substantial gasoline price increases.

Current Context

Prediction market data shows conflicting probabilities for September credit card spend. The Kalshi market tracks Carbon Arc's U.S. aggregated credit/debit-card panel, expressed as a year-over-year index where 100 equals the same month last year [1]. The September 2026 contract is scheduled to settle October 7, 2026, based on this index, not BP's own reported financial statements [1][2][3]. As of October 5, 2026, Kalshi displayed probabilities of 41% for spend above 98, 21% above 101, and 13% above 103.5. Yes prices were 71¢, 31¢, and 31¢ respectively, indicating thin or potentially stale/inconsistent market data that requires cautious treatment [1]. Independent market mirrors reported different probabilities for lower thresholds: CoinRithm indicated 99% for above 105.5, while Frenzy Capital showed 98% for above 105.5 and 97% for above 111.5 [2][3]. These figures conflict materially with the Kalshi page and should not be combined into a single precise forecast [2][3].
BP's latest financial reports do not include September credit card spend. The company released its second-quarter and first-half 2026 results on August 4, 2026, reporting a Q2 underlying replacement-cost profit of $5.732 billion, operating cash flow of $10.858 billion, and net debt of $22.251 billion [4][5][6]. These disclosures do not report September monthly credit-card spend [4][5][6]. BP's Q2 presentation identified October 30, 2026, as the planned date for third-quarter 2026 results, which is after the October 7 prediction-market settlement [7]. Recent company developments include Ian Tyler's appointment as BP chair on September 1, 2026, and continued investor focus on BP's portfolio, balance-sheet, exploration, and leadership outlook [8][9]. Available search results do not provide a high-quality, directly attributable expert consensus specifically forecasting the September card-spend index [8][9].
Available market evidence suggests positive year-over-year September card spend. The evidence leans toward growth above 100, though the exact level is unresolved due to sharply disagreeing sources [1][2][3]. Confidence is materially lower for thresholds around 105.5 or higher [1][2][3]. The official outcome should be checked after Carbon Arc's first reported value and the October 7 settlement [1][2][3].

3. Significant Price Movements

Notable price changes detected in the chart, along with research into what caused each movement.

Outcome: Above 109.5

📈 October 04, 2026: 84.0pp spike

Price increased from 10.0% to 94.0%

What happened: The primary driver of the 84.0 percentage point spike was a re-evaluation of BP's September 2026 credit card spend expectations, attributed to strong promotional offers like the BP rewards Visa card promotion that concluded on September 30, 2026, coupled with robust customer-facing performance and resilient U.S. consumer spending [1]. The market likely repriced the "Above 109.5" outcome as participants assessed the expected positive impact of these factors on September data after the promotion's conclusion, leading to the surge by October 4, 2026 [1][2]. Social media activity, particularly on Reddit, showed declining mentions and neutral sentiment for BP, indicating it was irrelevant to this specific price movement [3].

📉 September 28, 2026: 35.0pp drop

Price decreased from 52.0% to 17.0%

What happened: The requested 35.0 percentage point drop in the "BP Monthly Credit Card Spend in September" market on September 28, 2026, could not be corroborated by the available indexed sources [4]. Instead, the accessible market pages document a sharp rebound on October 5, 2026, with significant price increases for similar outcomes [4]. No specific contemporaneous news article or social media post was identified as a catalyst for either the reported drop or the later rebound [4]. Therefore, based on the provided information, social media was irrelevant, as the reported price movement itself lacks corroboration.

📈 September 27, 2026: 20.0pp spike

Price increased from 32.0% to 52.0%

What happened: No specific social media activity directly related to BP's September credit card spend index was identified in the provided research on September 27, 2026, indicating it was not a primary driver for the price movement. While general consumer spending trends showed strength, such as Barclays reporting 2.1% year-over-year card spending growth in August [5] and ongoing 5x spend bonuses [6], these were not new announcements specific to BP on September 27. Other BP-related news on that date focused on a Bumerangue discovery and share price fluctuations, not the third-party credit card spend index [7][8][9]. Therefore, a clear primary driver for the 20 percentage point spike on September 27, 2026, cannot be definitively identified from the available information.

Outcome: Above 107.5

📈 October 03, 2026: 21.0pp spike

Price increased from 71.0% to 92.0%

What happened: The primary driver for the 21.0 percentage point spike in the "BP Monthly Credit Card Spend in September - Above 107.5" prediction market on October 3, 2026, is not explicitly identified in the available research. No specific social media activity or traditional news catalyst for this particular date was found to cause the repricing [10]. While the market's central estimate for September spend shifted significantly upwards toward 114, indicating a strong belief in higher card spend, only generic explanations such as promotional offers or resilient U.S. consumer spending were suggested for the underlying trend [2][4][11][10]. Based on the available information, social media appears to have been irrelevant as a primary driver or contributing accelerant.

📈 October 02, 2026: 17.0pp spike

Price increased from 54.0% to 71.0%

What happened: The 17.0 percentage point spike in the "BP Monthly Credit Card Spend in September" market on October 2, 2026, for the "Above 107.5" outcome appears to be part of a broader upward repricing, with significantly larger percentage point increases observed for higher spend thresholds (e.g., Above 109.5 and Above 111.5) [2][11][4]. While BP's shares surged 10% in September amidst a broader energy rally and strong Q2 profits, the research does not definitively establish these events as the cause of the card-spend market repricing [12]. No reliable social media activity, such as posts from key figures or viral narratives, or definitive news reports were found directly linking to this price movement [2][1][13][11][4][12]. Therefore, social media was irrelevant to this specific price movement based on the available information.

4. Market Data

Contract Snapshot

For the "Above 114" contract on BP Monthly Credit Card Spend in September, a YES resolution occurs if BP's monthly credit card spend for September is above 114. A NO resolution occurs if the spend value is 114 or less. The market is scheduled for a maximum payout by October 6, 2026, with no special settlement conditions explicitly mentioned.

Market Discussion

The prediction market for BP's September 2026 credit card spend shows a strong consensus for year-over-year growth, with probabilities around 98-99% for values above 105.5, and active trading concentrated on the upper tail where 114 serves as a key uncertainty boundary [1]. However, as of October 5, 2026, no official or published BP monthly credit card spend figure for September 2026 could be located in public sources or company filings, indicating that market activity appears to be driven by interpretation rather than disclosed data [1].

5. What Major Economic Reports or Gasoline Price Shifts in September 2026 Could Materially Impact BP's U.S. Consumer Spend Index?

August Household Spending Growth6.1% year over year [1]
Federal Funds Target Rate3.75%–4.00% (effective Sep 16, 2026) [2]
EIA Regular Gasoline Price$4.157 per gallon (Sep 7, 2026) [3][4]
Consumer demand remained resilient in September 2026 despite persistent inflation. Major economic reports for September 2026 indicated robust consumer demand and household spending, with the US second-quarter GDP revised higher due to strong consumer activity [5][1][2]. August household spending growth reached 6.1% year over year, and card spending was approximately 4% above August 2025 levels [5][1]. In response to this persistent inflation, the Federal Reserve increased the federal-funds target by 25 basis points to 3.75%–4.00% on September 16, 2026, acknowledging the continued strength in domestic spending alongside elevated inflationary pressures [2].
Gasoline prices surged to record levels throughout September 2026. A sharp increase resulted in the highest monthly prices on record [3][4][6][7][8]. On September 7, EIA regular gasoline reached $4.157 per gallon, marking a 96.5 cents year-over-year increase, while AAA reported a national average of $4.277 on September 10 [3][4][6]. By September 14, EIA all-grades gasoline climbed to $4.455, contributing to a monthly average near $4.33, which exceeded the previous September record of $3.83 [7][8]. This significant fuel price shock was attributed to oil-market and geopolitical disruptions, including volatility in the Strait of Hormuz and Brent/WTI crude oil prices at or above $100 per barrel [3][6][7].

6. How Does Carbon Arc's Credit Card Panel Data Historically Correlate with BP's Official Reported Downstream Segment Financials?

Carbon Arc Sept Index Medianaround 114 (as of Oct 5, 2026) [1][2]
BP Downstream ReportingQuarterly/annual basis [3]
BP 4Q24 Convenience EBITDA$1.2 billion (versus $1.4 billion in 3Q24) [4][5]
Quantifying historical correlation between Carbon Arc data and BP's financials is not possible. Publicly available evidence does not allow for a quantifiable historical correlation between Carbon Arc's credit card panel data and BP's official reported downstream segment financials [1][3][6][4]. This is primarily due to the absence of public time series for Carbon Arc's BP monthly observations or matched BP downstream financials, coupled with the fundamental incomparability of BP's quarterly segment figures with a monthly U.S.-only card-spend index. While a directional, albeit noisy, qualitative relationship exists where stronger U.S. retail activity might support BP's Customers subsegment volumes, the Carbon Arc index is a U.S. aggregated credit/debit-card panel and not an official BP accounting metric [1].
The Carbon Arc index is an unreliable proxy for BP's total downstream financials. Significant differences in accounting scope, geography, timing, margins, and non-retail businesses mean the Carbon Arc index should not be considered a reliable proxy for BP's total downstream revenue, EBITDA, or profit [1][3][6][4]. BP's strategic downstream footprint is extensive, including over 20,000 fuel-retail sites, convenience stores, fleet relationships, aviation, refining, trading, and approximately 40,000 EV charge points, meaning a U.S. consumer-card panel only captures a limited portion of this segment [7]. As of October 5, 2026, the prediction market implied a median Carbon Arc September index of around 114, suggesting market expectation rather than an official BP financial outcome [1][2].
BP's Customers & Products segment reports are influenced by many factors. BP reports its downstream operations as the Customers & Products segment, providing figures on a quarterly or annual basis, primarily focusing on underlying replacement-cost profit before interest and tax [3]. Official disclosures indicate that BP's downstream financials are influenced by a broader range of factors beyond retail card transactions, such as seasonality, fuel and refining margins, trading activities, throughput, turnarounds, outages, foreign exchange fluctuations, and the overall performance of convenience and mobility services [4][5]. For instance, in 4Q24, Customers convenience & mobility adjusted EBITDA was $1.2 billion compared to $1.4 billion in 3Q24, while refining and trading adjusted EBITDA was negative $0.4 billion [4][5]. For the full year 2025, BP reported its highest Customers & Products underlying earnings since 2019 [3][6].

7. How Have Year-Over-Year Consumer Spending Trends at BP Compared to Competitors like Shell and ExxonMobil Throughout 2026?

BP Sept 2026 Implied Growth10%-14% (market pricing implied) [1]
BP Above 109.5 Probability97% likely (implied by market pricing) [1][2][3]
ExxonMobil Above 108 ProbabilityRoughly 93% (market-moves page) [4][5]
BP's September 2026 consumer spending showed strong market-implied growth. Market pricing suggested year-over-year consumer spending was positive, likely experiencing growth between 10% and 14% [1]. Although the official Carbon Arc U.S. credit/debit-card-spend index was not yet reported, market pricing indicated a 97% probability for an index above 109.5 [1][2][3]. This implied an expected September index above 109.5, though with some uncertainty regarding growth exceeding 14% [1]. This positive outlook was consistent with a broader demand backdrop, as U.S. consumer card spending rose 4.5% year over year in August 2026, and BP's market commentary highlighted promotions and resilient U.S. spending [1]. It is important to note that the evidence regarding BP's performance is market-implied, not an official company disclosure [1].
Competitors experienced positive yet less certain market indicators for September. Competitor markets for September also suggested positive outcomes, though seemingly with less certainty when compared to BP [4][5]. For instance, ExxonMobil's "Above 108" contract indicated an approximate 93% probability on relevant market-moves pages [4][5]. However, definitive realized indexes for competitors were not established based on the available information [1][4][5]. Furthermore, reliable probabilities or final values for Shell for September 2026 were not provided, making direct comparisons insufficient based on the available data [1][4].

8. What is the Precise Release Schedule for the Carbon Arc Data Used to Settle the Kalshi Market on October 7, 2026?

Carbon Arc Data Release ScheduleNo precise release schedule or guaranteed date and time for Carbon Arc data used to settle the Kalshi market on October 7, 2026 [1][2]
Kalshi Market Scheduled Timestamp02:29 UTC (October 6, 10:29 PM EDT) is a market schedule/expiration indicator, not a guaranteed Carbon Arc publication time [3][4][1]
Carbon Arc Index Update CadenceDaily, as new data arrives, with the first qualifying report available before settlement [3][4][1][2]
The available documentation does not identify a precise data release schedule. The documentation does not identify a precise release schedule or guaranteed release date and time for the Carbon Arc data used to settle the Kalshi market on October 7, 2026 [1][2]. The market's scheduled timestamp of 02:29 UTC (October 6, 10:29 PM EDT) functions as a market schedule or expiration indicator, rather than a guaranteed publication time for the Carbon Arc data [3][4][1].
Carbon Arc data refresh cadence varies, but updates daily. Carbon Arc's public data-schedule documentation indicates that the refresh cadence varies by asset [1]. Specific current schedules, including times, are displayed in the Library in Eastern Standard Time (EST) and are subject to operational shifts [1]. While a precise release clock or guaranteed date/time for the September 2026 BP asset is not identified, the Carbon Arc index, which aggregates U.S. credit/debit-card-panel spending, updates daily as new data arrives [3][4][1]. Consequently, the defensible schedule for this index is a daily update, with settlement using the first qualifying report available before the settlement date for the September 2026 BP Monthly Credit Card Spend index [1][2][3][4].

9. What Explains the Discrepancy in Implied Probabilities Between Kalshi's Market and Aggregators like CoinRithm for the September 2026 Outcome?

CoinRithm 24-hour volume$8.3K (on Above 111.5) [1][2][3][4]
Kalshi Above 98 probability41% (snapshot) [1][2]
CoinRithm Above 114 probability92%+ (October 5 snapshot) [1][2]
The apparent discrepancy in implied probabilities between Kalshi’s market and aggregators like CoinRithm for the September 2026 outcome primarily stems from time and quote mismatches. This is not due to differing September-2026 contracts, but rather how aggregators present data [1][2]. Aggregator pages frequently caution that displayed probabilities may be stale, indicating they can be cached, delayed, or derived from a selected quote rather than reflecting live executable bid/ask prices [3][4].
Different data snapshots across platforms illustrate the varying probabilities at distinct times. Kalshi’s search result indicated its page began October 4 with an earlier ladder, whereas CoinRithm’s October 5 data showed a +92-point move and approximately $8.3K in 24-hour volume on Above 111.5 [1][2][3][4]. For example, a Kalshi page snapshot presented probabilities such as 41% for Above 98, while CoinRithm’s October 5 snapshot reported significantly higher odds, including over 92% for Above 114 [1][2]. Direct comparison of probabilities across different thresholds and times is challenging, as market updates can appear inconsistent due to asynchronous page updates [1][2][4].
Kalshi YES prices, given in cents, approximate probabilities but do not guarantee a frictionless probability due to market factors. These factors include bid/ask spread, liquidity, order-book selection, fees, and stale trade data [1][2][4]. CoinRithm indicates that the underlying index for settlement is Carbon Arc’s daily-updating aggregated U.S. credit/debit-card panel, with settlement based on Carbon Arc's first reported value. This means late data updates and rapid trading could significantly alter displayed prices as the October 7 resolution date approaches [2][3][5]. The contract officially resolves on October 7, 2026, not September 30 [2][3].

10. What Could Change the Odds

Key Catalysts

The Kalshi BP Monthly Credit Card Spend in September 2026 market is set to settle on October 7, 2026 [1][2][3]. This market, measuring Carbon Arc's U.S. aggregated credit/debit-card panel indexed to the same month a year earlier, indicated a high probability for September 2026 spend to be above 105.5 and above 109.5 (roughly 98–99% odds), with about a 97% chance for above 111.5, as of October 5, 2026 [1][4][3]. However, the probability for spend above 114 was near 50% [1][4][3]. BP does not publicly disclose real-time monthly card-spend data in its normal financial reporting, making this prediction market an alternative indicator [5]. The market-implied base case is September 2026 BP card spend above 109.5 and likely above 111.5, but a print above 114 is materially less certain [1][4][3].
BP's next major company financial catalyst is expected with its Q3 2026 results in early November [5][6][7][8]. This follows a Q2 2026 underlying replacement-cost profit of $5.732 billion and operating cash flow of $10.858 billion, contributing to first-half operating cash flow of $13.718 billion [5][6][8]. Net debt at Q2-end stood at $22.251 billion, down from $25.309 billion in Q1 [5][6][8]. Bullish catalysts for BP stock include Brent crude above $100 in late September, analyst upgrades and higher price targets (JPMorgan cited a 675p target, HSBC cited 640p), continued debt reduction, restructuring/divestments, and stronger refining/trading conditions [6][7][9][8].
Conversely, bearish risks include potential reversals in oil, gas, refining, or trading margins [7][8]. Execution and valuation risks are associated with BP's planned $8–9 billion of 2026 divestment proceeds and the Castrol sale [7][8]. Remaining debt, activist pressure, and strategic risks related to emphasizing hydrocarbons during the energy transition also pose challenges [7][8].
