Should you build or buy Financial Market Data & Research Platforms?
Financial market data and research platforms deliver licensed real-time and historical pricing, exchange entitlements, broker research, and a professional messaging network to traders, analysts, and portfolio managers. Firms buy access as terminal seats or data feeds, because the underlying content is licensed from exchanges and data vendors, not owned by the firm.
Buy the platform and the data rights; you cannot build your way out of exchange fees, entitlements or the broker research library. Where a build pays is the research layer on top, the AskResearchGPT pattern, and that is a separate project from replacing the terminal.
Build it, buy it, or bridge?
When building makes sense
There is a real build case in this category, but it sits entirely above the data, not in place of it. Morgan Stanley's AskResearchGPT searches Morgan Stanley Research, which publishes more than 70,000 proprietary reports a year, for its investment banking, sales and trading, and research staff, and similar tools exist inside investment banking and research divisions at other firms, but none of these replace a Bloomberg, FactSet, Capital IQ, or LSEG seat. The raw market data, exchange entitlements, and broker research those staff rely on are still licensed separately. That is the shape of a credible build: a research or analysis layer, an internal chat assistant, or a custom dashboard, built on content and data a firm already owns or pays to license. What a firm cannot build around is the licensed data itself. Exchange entitlement fees, display-versus-business-use licensing terms, and broker research relationships are commercial and regulatory arrangements, not engineering problems, and no firm has documented replacing a terminal seat by building a data pipeline from public sources instead.
When buying makes sense
Buying is the clear call because the actual product in this category is licensed content and exchange access, not software a firm could replicate by hiring engineers. Bloomberg publishes no public list price; third-party cost trackers put a seat at $28,000 to $32,000 a year, and FactSet, Capital IQ Pro, and LSEG Workspace charge comparable amounts for their own bundles of pricing data, research, and messaging network access. That fee buys entitlements and broker relationships built over decades, not a UI a competent team could rebuild over a quarter. The work of consuming and displaying that data is generic across every firm that licenses it, which means the platform itself confers no competitive edge regardless of who owns it. License the data and workstation sized to your trading and research needs, and put in-house engineering effort into the proprietary research and analysis layer that sits on top of the licensed feed, where the actual differentiation lives.

Frequently asked
Why can't a firm just build its own Bloomberg Terminal alternative?
Because the product is licensed data and exchange entitlements, not a piece of software. Exchange fees, display-versus-business-use licensing terms, and broker research relationships are commercial arrangements a firm has to negotiate and pay for no matter who builds the display layer on top of them.
Are banks actually replacing terminal seats with AI tools?
No documented case shows that. Deutsche Bank's DB Lumina and Bridgewater's Pocket Analyst are built on top of licensed and proprietary content their firms already hold, and traders and analysts at those firms still rely on Bloomberg, FactSet, or similar terminals for live market data alongside them.
What does a Bloomberg Terminal seat actually cost?
Bloomberg publishes no public list price. Third-party cost trackers put a seat at $28,000 to $32,000 a year, before any additional data subscriptions a firm adds on top. FactSet, Capital IQ Pro, and LSEG Workspace price their bundles in a comparable range for similar breadth of data and research access.
What are the main financial market data and research platforms?
Representative vendors include Bloomberg Terminal, FactSet Workstation, S&P Capital IQ Pro, and LSEG Workspace. Firms typically choose based on which broker research library and messaging network their counterparties already use. B4 Pro scores the full set.
