What IOP Publishing does
IOP Publishing Limited (IOPP) is a society-owned scientific publisher and the publishing arm of the Institute of Physics, registered in England and Wales. The company publishes a portfolio of over 100 open access and hybrid journals, ebooks, conference proceedings, and science-news media, with its flagship consumer brand Physics World reaching approximately 695,000 average monthly page views and reporting 99% reader reliability. IOPP publishes on behalf of multiple learned societies including the American Physical Society, the European Physical Society, the Chinese Physical Society, the Japan Society of Applied Physics, the London Mathematical Society, and others, and 100% of its profits are reinvested into scientific and public good.
The company operates the IOPScience content delivery platform, serving approximately 90% of usage via institutional access, and integrates with OpenAthens, SeamlessAccess, and IPregristry.org for federated authentication. IOPP has built proprietary AI tools — the Duplicate Review Checker (machine-learning based, processing ~500,000 reviewer reports since 2020 and flagging ~2,500 duplicate-review cases) and Alchemist Review (an AI editorial assistant expanded across the majority of its proprietary journal portfolio in late 2025) — and is deploying AI-based citation-hallucination detection on manuscript submissions.
IOPP monetises through subscription-based institutional journal access, article publication charges (APCs) for open access, multi-year transformative read-and-publish agreements with consortia (including the TIB Consortium covering 80 German institutions and MALMAD covering Israeli institutions), and licensing of conference proceedings and ebooks. The go-to-market model is enterprise field sales targeting university, research institution, and corporate R&D accounts globally, supplemented by consortium partnerships and content licensing to platforms such as Elsevier's LeapSpace. Customer segments span academic researchers, institutional libraries, learned societies, and AI/technology companies licensing scientific content. IOPP maintains offices in Bristol (headquarters), Beijing, Tokyo, and Philadelphia, and operates the Peer Review Excellence certification programme with over 7,000 graduates and 22,000+ Trusted Reviewers.

IOP Publishing competitors and assessment
Company assessmentBroad incumbents
- Elsevier (RELX Group): Elsevier is the largest STM publisher globally with thousands of journals across disciplines. It is a strategic partner via LeapSpace but also a broad incumbent competitor offering cross-disciplinary packages that compete with IOP Publishing for institutional procurement budgets.
- American Chemical Society (ACS): ACS is a large scientific society publisher with extensive journal and book coverage in chemistry and adjacent physical sciences. It is comparable as a society-owned STEM publisher with similar institutional licensing economics.
Direct peers
- Wiley: Wiley publishes hundreds of peer-reviewed journals across scientific and scholarly disciplines with significant physics and materials science coverage. It directly competes for institutional subscriptions and transformative agreements.
- American Physical Society (APS): APS publishes flagship physics journals (Physical Review Letters, Physical Review, etc.) and is both a society-publishing partner and a direct competitor in physics. Comparability is high given overlapping author bases and subject coverage.
- Springer Nature: Springer Nature is one of the largest academic publishers with extensive journal and book portfolios across STM and HSS. It directly competes with IOP Publishing for physics, materials science, and interdisciplinary journal submissions and library procurement contracts.
- Taylor & Francis (Informa): Taylor & Francis publishes over 2,700 journals across HSS and STM and competes directly with IOP Publishing for transformative agreements, institutional subscriptions, and physics-adjacent journals.
- Cambridge University Press: Cambridge University Press publishes a substantial journal portfolio in physical sciences and mathematics, with similar society publishing arrangements and academic positioning. Direct competitor for institutional consortia and physics journal submissions.
- Oxford University Press: Oxford University Press publishes peer-reviewed journals across scientific disciplines including physical sciences. As a mission-aligned university press, it competes for institutional OA agreements and society partnerships in overlapping subject areas.
- AIP Publishing: AIP Publishing is the publishing arm of the American Institute of Physics and a direct peer society publisher focused on physical sciences. It publishes Applied Physics Letters, Journal of Applied Physics, and other titles that overlap with IOPP's subject coverage.
Emerging players
- SAGE Publishing: SAGE Publishing is a LeapSpace content licensing co-partner with IOP Publishing. It is comparable as a society-publishing-aligned academic publisher with growing STM presence, though its portfolio is more concentrated in HSS than IOPP's physics-led mix.
