## Short Answer

**Key takeaway.** Both the **model** and the **market** overwhelmingly agree that Anthropic is most likely to be assigned to the Information Technology sector before January 1, 2028, with only minor residual uncertainty.

## Key Claims (January 2026)

**- - Information Technology is favored due to Anthropic's B2B enterprise software and API revenue focus.** - Unassigned is unlikely given Anthropic's clear AI research and deployment business **model**.
- Communication Services shows low **probability**, lacking consumer-facing, ad-supported revenue streams.

### Why This Matters (GEO)

- AI agents extract claims, not arguments.
- Improves citation probability in summaries and answer cards.
- Enables fact stitching across multiple sources.

## Executive Verdict

**Key takeaway.** With a **0.1%** gap, the 2c **market** price largely reflects Octagon's **1.9%** **probability**, offering a 50x payout multiple.

### Who Wins and Why

| Outcome | Market | Model | Why |
| --- | --- | --- | --- |
| Information Technology | 81.0% | 78.7% | Anthropic's B2B enterprise software, API usage, and cloud services align with the Information Technology sector definition. |
| Unassigned | 10.0% | 8.8% | Anthropic has a clear AI business model, making it suitable for existing GICS classifications. |
| Real Estate | 1.0% | 1.2% | Anthropic's core business is AI development, not real estate ownership, development, or management. |

## Model vs Market

| Outcome | Market Probability | Octagon Model Probability |
| --- | --- | --- |
| Information Technology | 81.0% | 78.7% |
| Unassigned | 10.0% | 8.8% |
| Real Estate | 1.0% | 1.2% |
| Consumer Discretionary | 1.0% | 1.2% |
| Consumer Staples | 1.0% | 1.2% |
| Energy | 1.0% | 1.0% |
| Financials | 1.0% | 1.2% |
| Health Care | 1.0% | 1.2% |
| Industrials | 1.0% | 1.2% |
| Materials | 1.0% | 1.2% |
| Utilities | 1.0% | 1.2% |
| Communication Services | 2.0% | 1.9% |

- Expiration: January 11, 2028

## Market Behavior & Price Dynamics

This market's price action is completely static. The implied probability of Anthropic being assigned to the Communication Services sector has held flat at 2.0% since inception. There have been no price movements, spikes, or drops. The key technical feature is the total absence of trading activity. Zero contracts have traded, indicating a complete lack of market engagement or disagreement with the initial pricing.

The flat, low price and nonexistent volume suggest a strong, unchallenged consensus. Market participants appear to agree that a "Communication Services" classification is a very low probability event. This sentiment is consistent with external expectations that Anthropic will be classified under the Information Technology sector following its IPO, which is anticipated in Q4 2026 after a confidential S-1 filing on June 1, 2026.

Without any trading volume, there are no established support or resistance levels. The chart simply reflects the market's opening assessment, which has not been tested or revised by new information or capital. The market is effectively pricing this outcome as a tail risk and shows no interest in speculating on it.

## Contract Snapshot

A "Yes" resolution for a given sector occurs if S&P Global assigns Anthropic to that GICS sector, verified from S&P Global; otherwise, it resolves "No." The market opened on June 3, 2026, and will close early if a sector assignment occurs, or by January 11, 2028, with projected payouts 30 minutes after closing. If Anthropic is assigned to more than one GICS sector, "Yes" holders for each attributed sector will receive $1 divided by the number of assigned sectors.

## Market Discussion

Anthropic is recognized as an Artificial Intelligence (AI) company, classified within the Technology sector, specifically under Software & IT Services [[^]](https://www.true-naics.com/company/anthropic)[[^]](https://www.cbinsights.com/company/anthropic)[[^]](https://www.ai-market-watch.com/company/anthropic). Standard industrial classification frameworks, such as NAICS, typically categorize such technology and AI development companies under the 'Information' sector, which is distinct from 'Financials & Insurance' [[^]](https://www.ismworld.org/globalassets/pub/research-and-surveys/rob/nmi/wtidrob202606svcs.pdf)[[^]](https://www.ismworld.org/globalassets/pub/research-and-surveys/rob/nmi/fuelrob202605svcs.pdf)[[^]](https://www.ismworld.org/globalassets/pub/research-and-surveys/rob/nmi/m00nrob202602svcs.pdf)[[^]](https://www.ismworld.org/globalassets/pub/research-and-surveys/rob/taiwan/april-2026-taiwan-non-manufacturing-index.pdf). Anthropic confidentially filed its S-1 with the SEC on June 1, 2026, and is widely expected to proceed with an IPO, potentially as early as October 2026 [[^]](https://www.nytimes.com/2026/06/01/technology/anthropic-ipo.html)[[^]](https://pitchbook.com/news/reports/q2-2026-anthropic-the-s-1-expected-to-price-ai)[[^]](https://valueaddvc.com/blog/anthropic-ipo-2026-date-valuation-how-to-invest).

**Anthropic's GICS sector assignment sparks debate post-confidential S-1 filing**

Anthropic's GICS sector assignment sparks debate post-confidential S-1 filing. Anthropic's confidential S-1 filing, submitted on June 1, 2026, has initiated discussions among **market** participants regarding its Global Industry Classification Standard (GICS) sector [[^]](https://www.anthropic.com/news/confidential-draft-s1-sec)[[^]](https://www.cnbc.com/2026/06/01/anthropic-ipo-s1-prospectus.html)[[^]](https://x.com/AnthropicAI/status/2061478052257841495)[[^]](https://www.msci.com/indexes/documents/methodology/1_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20250220.pdf)[[^]](https://www.msci.com/indexes/documents/methodology/0_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20240801.pdf)[[^]](https://www.msci.com/downloads/documents/indexes/gics/GICS+Sector+Definitions+2023.pdf). While Information Technology and Communication Services are currently the primary sectors debated for Anthropic, the final GICS assignment will ultimately depend on the company's core revenue streams as detailed in its public prospectus [[^]](https://www.predictionmarkets.org/articles/is-anthropic-tech-read-the-fine-print-behind-a-**market**/)[[^]](https://kalshi.com/markets/kxanthropicsector/anthropic-sector-in-sp/kxanthropicsector-xx)[[^]](https://valueaddvc.com/blog/anthropic-ipo-2026-date-valuation-how-to-invest)[[^]](https://newsletter.semianalysis.com/p/anthropic-3q26-profit-over-1b-the).

GICS classification relies on primary revenue, enabling non-IT assignments. GICS classification is fundamentally based on a company's principal business activity, which is determined by its primary source of revenue as disclosed in official regulatory documents [[^]](https://www.msci.com/indexes/documents/methodology/1_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20250220.pdf)[[^]](https://www.msci.com/indexes/documents/methodology/0_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20240801.pdf)[[^]](https://www.msci.com/downloads/documents/indexes/gics/GICS+Sector+Definitions+2023.pdf). Factors that could lead to a classification outside of Information Technology include significant revenue generation from media, entertainment, or telecommunications services, which would place it in Communication Services [[^]](https://www.msci.com/indexes/documents/methodology/1_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20250220.pdf)[[^]](https://www.msci.com/indexes/documents/methodology/0_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20240801.pdf)[[^]](https://www.msci.com/downloads/documents/indexes/gics/GICS+Sector+Definitions+2023.pdf). Alternatively, substantial income from professional consultancy or research services could result in an Industrials classification [[^]](https://www.msci.com/indexes/documents/methodology/1_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20250220.pdf)[[^]](https://www.msci.com/indexes/documents/methodology/0_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20240801.pdf)[[^]](https://www.msci.com/downloads/documents/indexes/gics/GICS+Sector+Definitions+2023.pdf).

Specific S-1 financial details for alternative classifications remain confidential. The precise financial disclosures that will dictate Anthropic's GICS assignment are included within its confidential S-1 draft, which has not yet been made public [[^]](https://valueaddvc.com/blog/anthropic-ipo-2026-date-valuation-how-to-invest)[[^]](https://newsletter.semianalysis.com/p/anthropic-3q26-profit-over-1b-the). Consequently, the specific details that might lead to a classification other than Information Technology are not publicly known at this time [[^]](https://valueaddvc.com/blog/anthropic-ipo-2026-date-valuation-how-to-invest)[[^]](https://newsletter.semianalysis.com/p/anthropic-3q26-profit-over-1b-the).

## According to S&P and MSCI, what are the primary revenue and operational criteria that define the Information Technology sector under the GICS framework?

GICS Primary Classification Basis | Principal business activity based on revenue [[^]](https://www.msci.com/indexes/documents/methodology/0_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20240801.pdf)[[^]](https://www.msci.com/documents/1296102/11185224/MSCI_GICS_Overview.pdf)[[^]](https://www.msci.com/documents/10199/242721/MSCI_Global_Industry_Classification_Standard.pdf/88181a98-5eff-4ac7-8409-d30474fc6429) |
GICS Sub-Industry Threshold | Typically 60% of revenue [[^]](https://www.msci.com/indexes/documents/methodology/0_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20240801.pdf)[[^]](https://www.msci.com/documents/1296102/11185224/MSCI_GICS_Overview.pdf)[[^]](https://www.msci.com/documents/10199/242721/MSCI_Global_Industry_Classification_Standard.pdf/88181a98-5eff-4ac7-8409-d30474fc6429) |
IT Sector Components | Software development, IT services, technology hardware and equipment, and semiconductors [[^]](https://www.msci.com/downloads/documents/indexes/gics/GICS+Sector+Definitions+2023.pdf)[[^]](https://www.msci.com/documents/1296102/11185224/GICS+Methodology+2022.pdf) |

**GICS classifies companies primarily by their principal business activity and revenue**

GICS classifies companies primarily by their principal business activity and revenue. Under the Global Industry Classification Standard (GICS) framework, a company's principal business activity, which is typically determined by revenue, serves as the primary criterion for classification [[^]](https://www.msci.com/indexes/documents/methodology/0_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20240801.pdf)[[^]](https://www.msci.com/documents/1296102/11185224/MSCI_GICS_Overview.pdf)[[^]](https://www.msci.com/documents/10199/242721/MSCI_Global_Industry_Classification_Standard.pdf/88181a98-5eff-4ac7-8409-d30474fc6429). For sub-industry classifications, a common guideline mandates that at least **60%** of a company's revenue must derive from that specific activity [[^]](https://www.msci.com/indexes/documents/methodology/0_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20240801.pdf)[[^]](https://www.msci.com/documents/1296102/11185224/MSCI_GICS_Overview.pdf)[[^]](https://www.msci.com/documents/10199/242721/MSCI_Global_Industry_Classification_Standard.pdf/88181a98-5eff-4ac7-8409-d30474fc6429). Additionally, secondary factors like earnings and **market** perception are taken into account for classification purposes [[^]](https://www.msci.com/indexes/documents/methodology/0_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20240801.pdf)[[^]](https://www.msci.com/documents/1296102/11185224/MSCI_GICS_Overview.pdf)[[^]](https://www.msci.com/documents/10199/242721/MSCI_Global_Industry_Classification_Standard.pdf/88181a98-5eff-4ac7-8409-d30474fc6429).

The Information Technology sector encompasses software, IT services, hardware, and semiconductors. This sector broadly includes companies involved in software development, IT services, technology hardware and equipment, and semiconductors [[^]](https://www.msci.com/downloads/documents/indexes/gics/GICS+Sector+Definitions+2023.pdf)[[^]](https://www.msci.com/documents/1296102/11185224/GICS+Methodology+2022.pdf). More specifically, the 'technology hardware and equipment' category within this sector covers products such as communications equipment and computers [[^]](https://www.msci.com/downloads/documents/indexes/gics/GICS+Sector+Definitions+2023.pdf)[[^]](https://www.msci.com/documents/1296102/11185224/GICS+Methodology+2022.pdf).

## How does Anthropic's business model compare to the defining characteristics of companies in the Information Technology versus Communication Services sectors?

Revenue Derivation | Approximately 80% from API usage, enterprise contracts, and cloud marketplace pass-throughs (1][[^]](https://valueaddvc.com/blog/anthropics-business-model-how-the-ai-safety-company-makes-money)[[^]](https://www.revenuememo.com/p/how-does-anthropic-make-money)[[^]](https://fourweekmba.com/anthropic-business-model/)) |
Annualized Revenue | ~$9B+ (1][[^]](https://valueaddvc.com/blog/anthropics-business-model-how-the-ai-safety-company-makes-money)[[^]](https://www.revenuememo.com/p/how-does-anthropic-make-money)[[^]](https://fourweekmba.com/anthropic-business-model/)) |
IPO before Jan 1, 2028 | No public confirmation (9) [[^]](https://deepresearchglobal.substack.com/p/anthropic-fundamental-analysis-report) |

**Anthropic primarily operates a B2B, enterprise-focused business model**

Anthropic primarily operates a B2B, enterprise-focused business **model**. The company's revenue is heavily weighted toward enterprise software and infrastructure services. Approximately **80%** of Anthropic's estimated **$9** billion-plus annualized revenue is derived from API usage, enterprise contracts, and cloud marketplace pass-throughs [[^]](https://deepresearchglobal.substack.com/p/anthropic-fundamental-analysis-report)[[^]](https://valueaddvc.com/blog/anthropics-business-**model**-how-the-ai-safety-company-makes-money)[[^]](https://www.revenuememo.com/p/how-does-anthropic-make-money)[[^]](https://fourweekmba.com/anthropic-business-**model**/). This revenue structure indicates a focus away from consumer-facing, ad-supported products [[^]](https://deepresearchglobal.substack.com/p/anthropic-fundamental-analysis-report)[[^]](https://valueaddvc.com/blog/anthropics-business-**model**-how-the-ai-safety-company-makes-money)[[^]](https://www.revenuememo.com/p/how-does-anthropic-make-money)[[^]](https://fourweekmba.com/anthropic-business-**model**/).

Anthropic's revenue strongly aligns with the Information Technology sector. This sector explicitly includes software and IT services [[^]](https://www.msci.com/indexes/documents/methodology/1_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20250220.pdf)[[^]](https://www.msci.com/downloads/documents/indexes/gics/GICS+Sector+Definitions+2023.pdf)[[^]](https://www.msci.com/documents/1296102/5603800/GICS+Structure+Revisions+in+2018.pdf/1b11d2e8-c482-4000-89f3-190225f02dc3). Under the Global Industry Classification Standard (GICS) methodology, sector classification is determined by the business activity that generates over **60%** of a company's revenue [[^]](https://www.msci.com/documents/1296102/11185224/GICS+Methodology+2022.pdf). This **model** distinguishes Anthropic from the Communication Services sector, which is typically characterized by telecommunication, media, entertainment, and platforms primarily monetized through advertising or proprietary consumer-facing content distribution [[^]](https://www.msci.com/indexes/documents/methodology/1_MSCI_Global_Industry_Classification_Standard_GICS_Methodology_20250220.pdf)[[^]](https://www.msci.com/downloads/documents/indexes/gics/GICS+Sector+Definitions+2023.pdf)[[^]](https://www.msci.com/documents/1296102/5603800/GICS+Structure+Revisions+in+2018.pdf/1b11d2e8-c482-4000-89f3-190225f02dc3).

No confirmed IPO date exists for Anthropic before 2028. While Anthropic is a large private company often discussed in connection with potential mega-IPOs, there is no public confirmation of an initial public offering scheduled before January 1, 2028 [[^]](https://www.msci.com/indexes/markets-in-motion/megacap-ipos).

## How might the structure of Anthropic as a Public Benefit Corporation (PBC) influence its sector assignment by exchange officials at NYSE or Nasdaq?

Sector Assignment Basis | Determined by principal business activity and primary revenue source [[^]](https://www.ice.com/publicdocs/ICE_Uniform_Entity_Sector_Methodology.pdf)[[^]](https://www.readkong.com/page/industry-classification-benchmark-equity-v3-8-ground-1062104)[[^]](https://learn.stockopedia.com/en/articles/3513282-sector-classification) |
Influence of PBC Status | Unlikely to influence sector assignment by exchange officials [[^]](https://www.ice.com/publicdocs/ICE_Uniform_Entity_Sector_Methodology.pdf)[[^]](https://www.readkong.com/page/industry-classification-benchmark-equity-v3-8-ground-1062104)[[^]](https://learn.stockopedia.com/en/articles/3513282-sector-classification) |
Anthropic's Operational Identity | AI research and deployment company, unchanged by PBC status [[^]](https://www.anthropic.com/news/the-long-term-benefit-trust?939688b5_page=1)[[^]](https://corpgov.law.harvard.edu/2023/10/28/anthropic-long-term-benefit-trust/)[[^]](https://time.com/6983420/anthropic-structure-openai-incentives/)[[^]](https://www.forbes.com/sites/investor-hub/article/openai-vs-anthropic-ipo-comparison/) |

**Company sector assignment relies on principal business activity and revenue sources**

Company sector assignment relies on principal business activity and revenue sources. Exchange officials at NYSE or Nasdaq primarily determine a company's sector based on its principal business activity and primary revenue source, rather than its legal structure [[^]](https://www.ice.com/publicdocs/ICE_Uniform_Entity_Sector_Methodology.pdf)[[^]](https://www.readkong.com/page/industry-classification-benchmark-equity-v3-8-ground-1062104)[[^]](https://learn.stockopedia.com/en/articles/3513282-sector-classification). Industry classification frameworks, including GICS, ICB, or ICE Uniform Entity Sector, prioritize revenue-generating activities, assets, and profitability over corporate governance or mission-related designations like Public Benefit Corporation (PBC) status [[^]](https://www.ice.com/publicdocs/ICE_Uniform_Entity_Sector_Methodology.pdf)[[^]](https://help.fhrexchange.com/en/articles/12640853-industry-sector-allocation)[[^]](https://www.readkong.com/page/industry-classification-benchmark-equity-v3-8-ground-1062104)[[^]](https://learn.stockopedia.com/en/articles/3513282-sector-classification).

Anthropic's PBC legal structure does not alter its operational identity. Anthropic operates as a Delaware Public Benefit Corporation, allowing its board to balance financial interests with a public benefit purpose [[^]](https://www.anthropic.com/news/the-long-term-benefit-trust?939688b5_page=1)[[^]](https://corpgov.law.harvard.edu/2023/10/28/anthropic-long-term-benefit-trust/)[[^]](https://time.com/6983420/anthropic-structure-openai-incentives/)[[^]](https://www.forbes.com/sites/investor-hub/article/openai-vs-anthropic-ipo-comparison/). This legal structure, however, does not change its fundamental operational identity as an AI research and deployment company [[^]](https://www.anthropic.com/news/the-long-term-benefit-trust?939688b5_page=1)[[^]](https://corpgov.law.harvard.edu/2023/10/28/anthropic-long-term-benefit-trust/)[[^]](https://time.com/6983420/anthropic-structure-openai-incentives/)[[^]](https://www.forbes.com/sites/investor-hub/article/openai-vs-anthropic-ipo-comparison/). Given its primary business **model** of developing AI systems, **market** analysts and participants consistently classify Anthropic within the Technology or Artificial Intelligence sector [[^]](https://www.lines.com/prediction-markets/finance/anthropic-ipo-by)[[^]](https://www.coinrithm.com/en/prediction-markets/kalshi/kxipoanthropic-date)[[^]](https://manifold.markets/JonasVollmer/when-will-anthropic-ipo).

## What is the historical precedent for GICS sector assignment for recently-listed, large-cap AI companies and Public Benefit Corporations (PBCs)?

PBC GICS Classification Basis | Core revenue-generating business (like any other company) [[^]](https://www.msci.com/documents/1296102/11185224/GICS+Methodology+2023.pdf/d0971eca-cf6c-5c30-6982-8c0797d4799a?t=1679088757399)[[^]](https://www.asx.com.au/content/dam/asx/markets/trade-our-cash-market/methodology-gics.pdf)[[^]](https://www.fidelity.com/learning-center/trading-investing/markets-sectors/global-industry-classification-standard) |
Primary GICS Metric | Revenue, with secondary consideration for earnings and market perception [[^]](https://www.msci.com/documents/1296102/11185224/GICS+Methodology+2023.pdf/d0971eca-cf6c-5c30-6982-8c0797d4799a?t=1679088757399)[[^]](https://www.asx.com.au/content/dam/asx/markets/trade-our-cash-market/methodology-gics.pdf)[[^]](https://www.fidelity.com/learning-center/trading-investing/markets-sectors/global-industry-classification-standard) |

**Public Benefit Corporations follow standard GICS classification based on their core business**

Public Benefit Corporations follow standard GICS classification based on their core business. Their assignment is determined by their primary revenue-generating activities, mirroring the process for any other corporation [[^]](https://www.msci.com/documents/1296102/11185224/GICS+Methodology+2023.pdf/d0971eca-cf6c-5c30-6982-8c0797d4799a?t=1679088757399)[[^]](https://www.asx.com.au/content/dam/asx/markets/trade-our-cash-**market**/methodology-gics.pdf)[[^]](https://www.fidelity.com/learning-center/trading-investing/markets-sectors/global-industry-classification-standard). The Global Industry Classification Standard (GICS) methodology explicitly states there are no specific categories or special rules for PBCs, with classification primarily driven by revenue, and earnings and **market** perception serving as secondary considerations [[^]](https://www.msci.com/documents/1296102/11185224/GICS+Methodology+2023.pdf/d0971eca-cf6c-5c30-6982-8c0797d4799a?t=1679088757399)[[^]](https://www.asx.com.au/content/dam/asx/markets/trade-our-cash-**market**/methodology-gics.pdf)[[^]](https://www.fidelity.com/learning-center/trading-investing/markets-sectors/global-industry-classification-standard). OpenAI and Anthropic are notable examples of companies structured as Public Benefit Corporations [[^]](https://www.youtube.com/watch?v=gH4FTjDm9FQ).

Newly listed companies receive initial GICS based on IPO prospectus details. Their preliminary classification is established by the business activity descriptions and pro-forma financial results presented in their initial public offering prospectus [[^]](https://www.msci.com/documents/1296102/11185224/GICS+Methodology+2023.pdf/d0971eca-cf6c-5c30-6982-8c0797d4799a?t=1679088757399)[[^]](https://www.asx.com.au/content/dam/asx/markets/trade-our-cash-**market**/methodology-gics.pdf). However, the available research does not provide specific historical precedents for GICS sector assignments for large-cap AI companies beyond these general classification principles [[^]](https://www.msci.com/documents/1296102/11185224/GICS+Methodology+2023.pdf/d0971eca-cf6c-5c30-6982-8c0797d4799a?t=1679088757399)[[^]](https://www.asx.com.au/content/dam/asx/markets/trade-our-cash-**market**/methodology-gics.pdf)[[^]](https://www.fidelity.com/learning-center/trading-investing/markets-sectors/global-industry-classification-standard). Furthermore, it does not specify the actual sector assignments for other recently-listed, large-cap AI companies [[^]](https://www.msci.com/documents/1296102/11185224/GICS+Methodology+2023.pdf/d0971eca-cf6c-5c30-6982-8c0797d4799a?t=1679088757399)[[^]](https://www.asx.com.au/content/dam/asx/markets/trade-our-cash-**market**/methodology-gics.pdf)[[^]](https://www.fidelity.com/learning-center/trading-investing/markets-sectors/global-industry-classification-standard).
