Washington, D.C., Arizona and Colorado Lead in Business AI Use

Washington, D.C., Arizona and Colorado rank as the jurisdictions with the highest reported business use of artificial intelligence, according to a report cited by CPA Practice Advisor. The publication, which covers accounting and finance technology, placed the three jurisdictions ahead of other states in its ranking of self-reported AI adoption among businesses.

What the CPA Practice Advisor report found

The report names Washington, D.C., Arizona and Colorado as the top three locations by reported business AI use. The underlying write-up, as surfaced through Google News, does not break out specific adoption percentages for each jurisdiction or disclose the sample size behind the ranking. HTT News is reporting the ranking as attributed to CPA Practice Advisor and has not independently verified the figures behind it.

Why the underlying data is not fully public

CPA Practice Advisor's framing is built around "reported" AI use, a distinction that matters. Reported use typically reflects what businesses or survey respondents say they are doing, not independently measured usage logs from software vendors. That distinction can produce gaps between self-reported adoption and what companies actually deploy day to day, since employees may use consumer AI tools informally without an employer tracking or disclosing that activity. The source material reviewed for this story did not include methodology details, such as how businesses were surveyed or how many responded in each jurisdiction, so those specifics are omitted here rather than estimated.

How this compares with other workplace AI research

Separately, an organization highlighted the emotional dynamics of AI in the workplace, focusing on how employees respond psychologically to AI tools introduced by management, rather than on geographic adoption rates. That coverage underscores a broader pattern in current AI-at-work reporting: outlets are tracking both where adoption is happening and how workers feel about it, often as separate lines of inquiry rather than a single unified dataset. Taken together, the two pieces of reporting illustrate that the public picture of workplace AI use remains fragmented across trade press, pending fuller survey data from government statistical agencies or large-scale academic studies.

What terms like "reported AI use" actually mean

For readers unfamiliar with the terminology in adoption rankings like this one, a short glossary helps:

• Reported AI use: Businesses or individuals stating, usually through a survey, that they use AI tools in some capacity, without independent verification.
• Adoption ranking: An ordering of regions or sectors based on reported or measured use, which can vary widely depending on survey design.
• Workplace AI tools: Software ranging from writing assistants to industry-specific automation, used either with employer sanction or informally by individual employees.

Many of the informal tools workers reach for, such as the mindfulAI Keyboard, fall into that last category: employee-chosen apps that rarely show up in official adoption counts even when they are in daily use.

What happens next on tracking state-level AI adoption

The CPA Practice Advisor item adds to a running list of 2026 reporting on where AI use is concentrating across U.S. businesses. On Sept. 16, 2026, separate coverage examined the emotional and cultural side of AI rollout in workplaces, a parallel thread to the geographic rankings now circulating. Readers looking for firmer numbers on business AI adoption by state will need to watch for primary survey data, such as releases from the U.S. Census Bureau's business trends surveys or sector-specific trade groups, since the current report does not itself publish a detailed data table alongside its ranking. HTT News will update this story if CPA Practice Advisor or another primary source publishes the full methodology and figures behind the Washington, D.C., Arizona and Colorado ranking.

How businesses can read a ranking without a public methodology

Executives weighing a report like this one face a practical problem: the ranking offers an order of jurisdictions but no table showing how far apart Washington, D.C., Arizona and Colorado sit from the rest of the country, and no description of who was surveyed, according to the material reviewed for this story. CPA Practice Advisor's audience of accounting and finance professionals means the ranking likely draws on client or industry contacts tied to that trade, rather than a randomized national sample, though the source did not state that explicitly. Treating the three named jurisdictions as directionally ahead, rather than precisely measured, is the more defensible reading until a fuller data set appears.

Does self-reported AI use match actual adoption

The gap between what a business tells a surveyor and what its employees do with AI tools day to day is not unique to this report. Self-reported figures in adoption surveys generally capture sanctioned, visible use, such as a company rolling out an approved chatbot, while informal use of consumer AI apps by individual staff members often goes undisclosed to employers and, by extension, to surveyors. That dynamic means jurisdiction-level rankings built on reported use may understate total AI activity in any state, including those not named in the CPA Practice Advisor list, a limitation the source material does not resolve.
