This excludes publicly traded companies (e.g., Big Tech companies) and companies’ internal spending, such as R&D or infrastructure. Expressed in US dollars, adjusted for inflation.","descriptionProcessing":"- Reporting a time series of AI investments in nominal prices would make it difficult to compare observations across time. To make these comparisons possible, one has to take into account that prices change (inflation).\n- It is not obvious how to adjust this time series for inflation, and our team discussed the best solutions at our disposal.\n- It would be straightforward to adjust the time series for price changes if we knew the prices of the specific goods and services purchased through these investments. This would make it possible to calculate a volume measure of AI investments and tell us how much these investments bought. But such a metric is not available. While a comprehensive price index is not available, we know that the cost of some crucial AI technology has fallen rapidly in price.\n- In the absence of a comprehensive price index that captures the price of AI-specific goods and services, one has to rely on one of the available metrics for the price of a bundle of goods and services. Ultimately, we decided to use the US Consumer Price Index (CPI).\n- The US CPI does not provide us with a volume measure of AI goods and services, but it does capture the opportunity costs of these investments. The inflation adjustment of this time series of AI investments, therefore, lets us understand the size of these investments relative to whatever else these sums of money could have purchased.","type":"int","grapherConfigIdETL":"019dbf12-d8b1-7d12-8376-e13e04e3b1ad","datasetName":"AI Index Report","updatePeriodDays":365,"datasetVersion":"2026-04-20","nonRedistributable":false,"display":{"unit":"constant 2021 US$","shortUnit":"$","numDecimalPlaces":0},"schemaVersion":2,"processingLevel":"major","presentation":{"attribution":"Quid via AI Index Report (2026); U.S. Bureau of Labor Statistics (2026)","topicTagsLinks":["Artificial Intelligence"]},"descriptionKey":["This data focuses on external private-market investment, such as venture-capital and private-equity deals.","It does not include internal corporate R&D, capital expenditure (CapEx), or public-sector funding.
