Kalshi launches sector-level KPI markets settled on Carbon Arc data
New arrays let traders bet on industry indices such as AI app downloads and sportsbook ad spend.

Key Takeaways
- Kalshi launched sector-level KPI contracts on 23 October 2026 that settle on Carbon Arc Prisms data.
- Each array is an equally weighted mean of named companies' year-on-year indices, where 100 equals the prior year.
- Carbon Arc is the settlement source for 109 Kalshi series including Online Sportsbook Ad Spend (127.45 in September) and Casino Ad Spend (71.34).
- A CFTC filing search through 22 October shows no certification explicitly describing the new sector KPI contracts or a Part 40 amendment adding Carbon Arc.
Kalshi began listing sector-level KPI contracts on 23 October 2026 that settle on Carbon Arc's Prisms data, letting traders take positions on industry-wide indices—for example AI app downloads or fast food card spend—rather than on individual companies. The contracts were first listed on 15 October and the company disclosed the new class of event contracts in a 23 October announcement. Carbon Arc already serves as the settlement source for 109 Kalshi series, including Online Sportsbook Ad Spend and Casino Ad Spend.
What Kalshi has launched
Kalshi's sector KPI contracts aggregate the same metrics it uses for single-company markets across a set of named firms. Each sector "array" is an equally weighted mean of its members' year-on-year indices, where 100 indicates parity with the prior year. The arrays cover credit card spending, point-of-sale sales, foot traffic and app downloads across industries.
Kalshi's publicly available market data lists nine sector arrays. Examples include:
AI chat app downloads: ChatGPT, Claude, Gemini and Grok at 25% each
Fast food card spend: McDonald's, Starbucks, Chipotle, Wendy's and Chick-fil-A at 20% each
Other arrays: big-box card spend, delivery, streaming and rideshare app downloads, and energy drink, nicotine and soda point-of-sale spend
Each contract asks whether the month's index will finish above a stated strike. Kalshi records the settlement value a few days after the month ends (for example, four days for the fast food array and seven days for AI apps); later revisions do not count.
By 24 October the AI chat apps array had traded 332 contracts and the fast food array about 5,670 contracts. Kalshi said the contracts open hedging uses for retailers, restaurant operators and app developers and that prices form a "crowdsourced, continuously updated forecast" of industry direction. Jack Such of Kalshi told Business Insider the aim was to "ETF-ify" its corporate KPI markets.
"Atomising equities into events and KPIs is one of Kalshi's best use cases," said Kalshi chief executive Tarek Mansour, calling sector-level arrays "the next logical step."
Carbon Arc's role and existing coverage
Carbon Arc, founded in 2021, supplies the Prisms indices that will settle the sector contracts. The company describes itself as "the neutral data layer for the AI economy" and lists Kalshi among clients alongside Morgan Stanley, Perplexity and Paychex. Carbon Arc claims more than 500 proprietary data assets across eight sectors.
Kalshi's trade API shows 109 series that name Carbon Arc as their settlement source: 34 on company card spend, 24 on app downloads and 11 on advertising spend by category. Specific September settlements include:
Online Sportsbook Ad Spend settled at 127.45, which Kalshi defines as 27.45% growth vs September 2025
Casino Ad Spend settled at 71.34, a fall of about 29% vs September 2025
DraftKings downloads settled at 161.98 for September
FanDuel downloads settled at 62.5 for September
September volumes on single-company events were large: the sportsbook advertising event traded 66,443 contracts and the DraftKings downloads event traded 119,647 contracts.
Kalshi's filings identify Carbon Arc's card data as coming from a panel and bar certain panel providers, including staff of Facteus and the nine underlying provider sources, from trading.
Regulatory filings and the open jurisdiction question
Kalshi self-certifies contracts with the US Commodity Futures Trading Commission. A search of KalshiEX product and rule filings on the CFTC website through entries dated 22 October found no certification that describes the new sector KPI contracts and no Part 40 amendment adding Carbon Arc as a source. Kalshi links a file named CARBONARC.pdf to some markets; that file is a 16 July 2025 self-certification of a generic economic statistics contract that contemplates adding a new source via a Part 40 amendment. A separate Kalshi filing on 18 June 2026 that names Carbon Arc covers rankings of company credit card spend.
The SEC's 13 October 2026 decision approving Cboe's binary KPI options treated those products as options on a security because they were limited to issuers with listed equity and settled on KPIs companies report in SEC filings. The SEC said that determination "does not foreclose" other structures and acknowledged that similar products "may be structured in different ways and be subject to CFTC jurisdiction." Kalshi's sector arrays differ from Cboe's structure in two ways: they settle on a vendor's panel estimate rather than company disclosures, and arrays blend several companies rather than targeting a single issuer.
The agencies have not issued a definitive ruling on whether a vendor estimate of a company's metric constitutes an issuer-specific event; that question sits inside the joint request for comment on swap definitions issued on 18 June. The CFTC has since proposed to define event contracts as swaps, and Kalshi was among commenters urging the SEC to wait for clearer guidance. Kalshi's regulatory position remains tied to the CFTC self-certification process.regulation
Market mechanics and operator exposure
Because Kalshi's ad spend and download contracts settle on Carbon Arc numbers, operators do not themselves produce or correct the settlement figures. Kalshi recorded DraftKings' September download index at 161.98 and FanDuel's at 62.5, and those values determined settlements regardless of any operator-published figures.
Kalshi's ad spend rules list source-agency staff and holders of non-public information among standard trading prohibitions; the June filing bars Carbon Arc staff, panel providers and company insiders with access to their own card spend from trading. The article's sources note that an operator's marketing team will often know budgets before a panel measures them, and prior cases — such as the KPMG-related Polymarket matter referenced in regulatory discussion — indicate markets tied to company data attract attention from insiders.
Kalshi positions the arrays as hedging tools, but current trading in many series is dominated by retail-sized $1-notional contracts in high volumes. The product sits beside Cboe's clearing development: Cboe Clear U.S. received temporary SEC registration on 23 October 2026 and KPI options are planned for Robinhood in Q4 2026. Whether regulators treat a vendor estimate as a commodity input or an issuer-related event will determine how far Kalshi can expand these products.
What to watch next
Watch for a Part 40 amendment or a new Kalshi certification that explicitly names Carbon Arc as a source, and for any agency guidance interpreting vendor estimates versus issuer-reported KPIs. Market volumes and any evidence of commercial hedging by retailers or app developers will also influence how the product is judged by regulators and industry participants.
