Projected Growth in FDA-Approved Artificial Intelligence Products Given Venture Capital Funding

Abstract

PurposeMedical imaging accounts for 85% of digital health’s venture capital funding. As funding grows, it is expected that artificial intelligence (AI) products will increase commensurately. The study’s objective is to project the number of new AI products given the statistical association between historical funding and FDA-approved AI products. MethodsThe study used data from the ACR Data Science Institute and for the number of FDA-approved AI products (2008-2022) and data from Rock Health for AI funding (2013-2022). Employing a 6-year lag between funding and product approved, we used linear regression to estimate the association between new products approved in a certain year, based on the lagged funding (ie, product-year funding). Using this statistical relationship, we forecasted the number of new FDA-approved products. ResultsThe results show that there are 11.33 (95% confidence interval: 7.03-15.64) new AI products for every $1 billion in funding assuming a 6-year lag between funding and product approval. In 2022 there were 69 new FDA-approved products associated with $4.8 billion in funding. In 2035, product-year funding is projected to reach $30.8 billion, resulting in 350 new products that year. ConclusionsFDA-approved AI products are expected to grow from 69 in 2022 to 350 in 2035 given the expected funding growth in the coming years. AI is likely to change the practice of diagnostic radiology as new products are developed and integrated into practice. As more AI products are integrated, it may incentivize increased investment for future AI products.
