Are there any market research publishers that focus on space investment trends and competitive positioning?

Yes. A few market research and industry intelligence publishers track the space economy, including investment trends, company funding, competitive landscapes, and market positioning.

Publishers / research firms to look at

• Space Capital – Known for its Space Investment Quarterly and broader analysis of venture funding, technology stacks, and ecosystem positioning across the space economy.
• BryceTech – Produces space market reports covering commercial space trends, launch, satellites, defense-space overlaps, and competitive landscape analysis.
• Novaspace (formerly Euroconsult) – Strong on satellite, launch, Earth observation, and downstream markets, often with competitive benchmarking and market sizing.
• Northern Sky Research (NSR) – Publishes detailed reports on satcom, launch, EO, and in-orbit services, often with competitive positioning and market share perspectives.
• Seradata – Good for space industry data and market intelligence, especially launch and satellite market tracking.
• Payload – More news/analysis than classic market research, but useful for funding, M&A, and competitive moves in the space sector.
• Kosmic Partners / similar boutique advisory firms – Some boutique players publish periodic insights on space investment and corporate strategy.
