Investing.com’s AI Investing Index ranks California first among U.S. states for AI-related investment activity, with Ohio and Colorado tied for second. The analysis covers 12 months of user activity in investment research and engagement with AI-focused stocks, adjusted for each state’s audience size. It measures activity on Investing.com, not the share of all investors in each state using AI.
California ranks first in Investing.com’s new analysis of where U.S. investors use AI in investment-related activity, while Ohio and Colorado tie for second. The index draws on 12 months of platform user activity involving AI-assisted research and engagement with AI-focused stocks, adjusted for audience size in each state; it is not a survey of all U.S. investors.
Florida and Texas complete the top five, according to Investing.com. The next tier includes Utah, Hawaii, Michigan and Minnesota, the company said. New York ranks 13th, while New Jersey ranks 27th. The results differ from a map based on traditional financial-industry hubs, though the index measures activity among Investing.com users rather than the total investing population in each state.
The ranking combines two kinds of activity: use of AI for investment research and engagement with AI-focused stocks. Investing.com says Florida had the highest level of AI-assisted investment research among the states included, while Pennsylvania led in engagement with AI-focused stocks. Those state-level findings describe different measures and do not mean either state ranked first overall.
The platform says the activity it analyzed covered research into stock statistics, technical analysis, company news, economic events, dividends and financial statements. Its release does not provide state-by-state raw totals, the precise dates covered, or a breakdown showing how much each measure contributed to the combined index.
AI Research Reaches Beyond Finance Hubs
The findings point to AI-related investing activity outside established finance centers, with Ohio and Colorado placing above New York in the overall ranking. If the pattern reflects wider use beyond the platform’s audience, AI tools could make some forms of investment information easier for retail investors to access regardless of location. That possibility is the interpretation offered by Investing.com, not a conclusion independently established by the index.
Investing.com Senior Analyst Thomas Monteiro said the data shows people doing more research. He argued that AI has made information previously out of reach available to retail investors and described the trend as making them more sophisticated. The ranking alone does not measure investment knowledge, the quality of research, trading performance or whether AI use improves financial outcomes.
The distinction matters to readers using AI for financial decisions. A state ranking can show where activity is concentrated within a particular service, but it does not establish that AI-generated analysis is accurate, suitable for an individual, or a substitute for reviewing primary financial information.

What the Index Measures
Investing.com says its AI Investing Index analyzed 12 months of U.S. user activity in two areas: using AI for investment research and engaging with AI-focused stocks. It adjusted the activity for audience size in each state. The release does not explain the full weighting method, define every qualifying action, or state the exact collection period, so the ranking should be read as a platform-based comparison rather than a census of investor behavior.
The release also cites a separate March 2026 survey in which 62% of U.S. retail investors said they had used AI to help inform an investment decision; more than half reportedly expected to use it more. The source material does not identify the survey’s sample size, polling method or sponsor, and those survey results are separate from the index’s activity data.
Investing.com says the U.S. placed 19th among 66 qualifying countries in its wider analysis. Italy, Poland, Israel, Chile and Argentina were the global top five. That international ranking is additional company-reported context; the published U.S. state results do not by themselves explain why the country placed 19th.

Limits of the State Rankings
The release does not specify the exact 12-month dates, the index’s weighting formula, the number of users behind each state result or the amount of activity recorded. It also does not say whether users’ locations were verified or how the company handled people who may use the service while traveling.
Because the measure is based on Investing.com user activity, the ranking cannot show what share of all investors in each state uses AI. The release does not establish whether the results represent statewide behavior, explain why California ranked first, or show that AI use led to better investment decisions. No independent validation of the index methodology is described in the source material.

Full Dataset and Method Details
Investing.com directed readers to its full U.S. state ranking and the underlying AI Investing Index dataset. Those materials may provide additional detail on state results and methodology; the press release itself does not set out a schedule for further analysis or updates.
Readers assessing the findings can compare the published ranking with the underlying measures, including the separate state leaders for AI-assisted research and AI-stock engagement. Until the collection dates, weighting and audience composition are clear, the results are best treated as a company-reported snapshot of activity, not a definitive measure of AI use by all American investors.
