The financial services industry is undergoing appreciable operational and technological change, driven by demand for high-quality data and the well-documented benefits offered on the back of cloud-based services.
This whitepaper, based on a 12-question survey of 31 capital markets professionals from a range of firms across the North American, European Union, and UK financial services industries, reveals that real-time and historical tick data are crucial to the majority of respondents, supporting their day-to-day operations and long-term analysis.
Unsurprisingly, firms continue to look for ways to wean themselves off of legacy systems and technologies, instead of opting for RESTful application programming interfaces, cloud-native formats such as Apache Parquet, and analytics tools such as Python and Snowflake. According to the survey, Python is now the dominant programming language, followed by SQL and Java.
This runs true with our day-to-day experience at OneTick and is the major driver for our mission to maximize OneTick interoperability at both the data and API layers.
Some key findings include:
While respondents recognize the benefits of scalability, flexibility and broader data access on the back of adopting cloud-based services, they remain cautious due to cost and implementation complexity. Regardless, cloud adoption is reshaping analytics by lowering operational demands. The survey also highlights artificial intelligence’s growing role across the industry, with firms focusing on improving data quality as a means of enhancing AI-driven insights.
The survey’s findings highlight an industry that is simultaneously diverse in its operational requirements and increasingly unified around a modern, cloud-centric analytics stack. Across firms’ types and regions, respondents demonstrated a need for flexible access to a range of data types, latencies and delivery mechanisms, reflecting the diversity of investment strategies and business functions synonymous with today’s markets.
Despite this diversity, strong consensus emerged around a number of themes. Python— especially bespoke, performance-optimized variants—is clearly the dominant language for developing analytics, valued by users for its transparency, speed of development and rich ecosystem. Cloud-native platforms such as Snowflake and Databricks are similarly well established, enabling firms to store and analyze vast datasets while integrating advanced analytics and AI capabilities.
As if the industry needed any more convincing, the survey reinforces the notion that the cloud model will, at some point, be the only model used by capital markets firms to access their technology, data and ancillary services.
While cost concerns, migration complexity and vendor lock-in remain key barriers to overcome, respondents clearly recognize the benefits of scalability, elasticity, access to additional datasets and faster time-to-market.
Crucially, most firms now see the cloud as a direct driver of reduced analytics costs and lower maintenance overheads, while also supporting efficient experimentation and deployment.
Finally, AI is already shaping firms’ analytics strategies, particularly when it comes to alpha generation and ease of access to insights. However, the emphasis respondents place on data quality is a reminder that AI’s value is directly contingent on the quality and trustworthiness of the data it consumes. As a whole, these findings point to an industry converging on cloud-based, AI-enabled analytics where flexibility, efficiency and speed are the key competitive differentiators.
