What General Index does
General Index (GX) is a London-headquartered, FCA-regulated energy benchmark provider founded in 2021 that aggregates trade data from 150+ data partners to produce over 5,000 daily price indices across crude oil, refined products, natural gas, LPG/NGL, tank storage, marine fuels, hydrogen, carbon, biofuels, sustainable aviation fuel (SAF), and Guarantees of Origin markets. Its core technology applies algorithmic index methodologies to 400,000+ monthly trades with expert market sign-off, replacing traditional journalist-opinion-based pricing with data-led benchmarks whose methodology has been audited against IOSCO principles for 494 indices in 2023 and 3,694 indices in 2024.
The company distributes data through the GX API (Python-accessible), the GX Go web platform (launched March 2025), Excel, Snowflake, and embedded integrations with Bloomberg Terminal, ICE Connect, LSEG Workspace, FactSet, and Enverus. Twenty-one tradeable derivatives linked to GX benchmarks are listed on ICE across US crude swaps and European gasoline instruments, embedding the methodology into exchange-traded and physical-contract pricing.
Revenue is generated via subscription and licensing models with multi-year enterprise contracts, serving energy majors and NOCs (Shell, BP, ExxonMobil, TotalEnergies, Glencore, ADNOC, INEOS, Neste, Pertamina), diversified corporates (Rio Tinto, ArcelorMittal, BASF), financial institutions (Two Sigma, Capula, Acadian, Man Group, Mizuho), and consulting firms (Rystad, Wood Mackenzie, Energy Aspects). Headcount of 45-100 operates across London, Krakow, Singapore, and Houston, with total disclosed funding of approximately $22 million plus £3.5 million of venture debt across Seed (2021), Series A (February 2024), Series A extension (October 2025), and HSBC debt facility (April 2026).

General Index competitors and assessment
Company assessmentBroad incumbents
- S&P Global Commodity Insights (Platts): The dominant physical commodity benchmark publisher (Platts brand) covering crude, refined products, natural gas, and increasingly energy transition markets. Closest direct competitor to General Index's core business, with vastly larger scale, established customer base, and decades-long incumbency at major IOCs and trading houses.
- ICIS (RELX): Major petrochemical and energy market intelligence provider under RELX, offering price assessments and benchmarks across refined products, petrochemicals, and increasingly energy transition. Competes with GX on refined products and is expanding into adjacent commodity benchmark coverage.
- Wood Mackenzie: Major energy research and consultancy firm (now part of Verisk) covering upstream, downstream, and energy transition markets. Overlaps with GX in serving energy trading desks and consultancies, though more focused on long-form research than daily benchmarks.
- BloombergNEF: Bloomberg's energy transition research arm providing analysis and benchmark data across renewables, carbon, hydrogen, and clean transport. Comparable to GX's energy transition index suite, but bundled into Bloomberg's broader subscription ecosystem.
- Rystad Energy: Independent energy research and data provider covering oil and gas, renewables, and energy transition. Overlaps with GX in serving enterprise energy customers with data products, though with greater emphasis on upstream analytics than daily price benchmarks.
Direct peers
- Argus Media: Independent commodity price reporting agency with strong coverage of crude, refined products, LPG, and energy transition markets. Directly competes with GX across many of the same daily indices and shares the same enterprise customer base.
- OPIS (Dow Jones): Specialist in refined products, jet fuel, and renewable fuels pricing benchmarks, acquired by Dow Jones. Direct competitor in NWE/US gasoline and SAF/biofuel benchmark categories where General Index is also building.
Regional players
- RIM Intelligence: Asia-focused energy and commodity price reporting agency with strong Japanese and broader APAC presence. Comparable to GX in methodology (daily price assessments) but primarily serves Asian markets where General Index is building a presence via its Singapore office.
Emerging players
- Vortexa: Technology-led commodities data and analytics platform focused on oil, gas, and shipping flows. Comparable in its technology-first approach and energy data focus, with overlap in marine fuels and tanker market intelligence.
- Kpler: Data and analytics platform for commodity markets covering oil, gas, and dry bulk flows. Comparable as a modern, technology-driven alternative to legacy market data providers, with overlap in energy commodity intelligence.
