FBI logged 22,000 AI-linked fraud complaints in its first year of counting them

The bureau's 2025 total of roughly $893 million comes only from victims who filed and from cases where investigators could identify the AI, and two of its subtotals overlap enough to exceed it. It is a floor.

What happened

  • The FBI's Internet Crime Complaint Center tracked complaints with an artificial intelligence connection for the first time in its 2025 annual report, logging more than 22,000 of them and roughly $893 million in reported losses.
  • Investment fraud accounted for $632 million of the reported AI-connected losses, the largest single category in the bureau's breakdown.
  • People over 60 accounted for $352 million of the same reported total, according to the bureau's figures.
  • The count includes only victims who filed a complaint with the FBI, and only cases in which investigators could identify a role for AI.
  • The cyber insurer Resilience reported that more than 85% of the losses in its claims portfolio in the first half of 2026 came from attacks aimed at people rather than at systems.

Why it matters

  • constraint With a single year in the series, the $893 million cannot support a claim that AI-assisted fraud is growing; any growth story has to be borrowed from a forecast.
  • contradiction The household framing and the loss data pull in different directions. What the evidence supports is a move from systems to people. A finance department's video call is in the same class as a grandparent's phone.
  • decision The cues households were taught to screen on, typos and a voice that sounds wrong, sort nothing now, so verification has to be a callback on every money request regardless of how the message sounded.
  • exposure Money leaves on instant rails within minutes of a takeover. The last party able to stop it is the account holder, not the bank's detection system.

The two subtotals inside the FBI's count do not fit inside its total. Investment fraud accounts for $632 million of the $893 million reported [3][2], and victims over 60 account for $352 million [4]. Added, that is $984 million, about $91 million more than the whole [18]. An over-60 investment-fraud victim sits in both categories, so these are overlapping cuts of one pool. Investment fraud on its own is 71% of the reported money [21].

Divide the losses by the complaints and the average reported loss is about $40,600 [19]. A mean sitting behind an investment-fraud total is pulled up by the largest victims. And the $40,600 is an upper bound anyway, since the count is "more than 22,000" [2].

2025 is the first year the Internet Crime Complaint Center tracked the AI connection at all [1], so the $893 million is the whole series [23]. The counting rules matter more than the size of the total. Only victims who reported are in it, and only cases where AI's role could be identified [5]. If the number rises next year, that could be more AI fraud or better recognition of it.

Cloning a voice takes a few seconds of audio and cheap consumer tools [11]. In one study, listeners identified an AI-generated voice about 60% of the time [7]. The task design decides what that rate means, and the article gives the rate alone [22].

The best-documented losses in the piece belong to companies. A finance employee at the design firm Arup wired about $25 million in 2024 after a video meeting staffed by deepfakes of the chief financial officer and several colleagues [8]. Anthropic disrupted an espionage campaign last fall in which an AI agent performed 80% to 90% of the intrusion work against roughly 30 targets, financial institutions among them [10]. Those come from a firm's own accounting and a vendor's incident report. The $893 million comes from complaint forms [5].

The growth claim rests on a projection. Deloitte expects US fraud losses of $40 billion by 2027, up from $12.3 billion in 2023, with AI helping push them there [6]. That is 3.25 times in four years, about 34% a year compounded [20].

The author of the Conversation piece, a finance professor who studies household finance and how people use AI to make money decisions, wrote: "I believe the most consequential AI security story right now isn't unfolding in server rooms, but at kitchen tables" [13]. The defense recommended there is a procedure. "Banks defend their own wire rooms with procedures, not vigilance," the author wrote [14]. The household version is to hang up on the suspicious call and dial a number you already know, such as your bank's fraud hotline [15].

What to watch

  • The 2026 IC3 report. It would give the AI-connected series its second data point and the first comparison worth making.
  • Whether Resilience's people-aimed share of claims losses holds in the second half of 2026 or was a first-half artifact.
  • Whether Deloitte's 2024 and 2025 actuals are tracking the 34%-a-year path implied by its $40 billion 2027 figure.
