Adults Using AI Companions Daily
Adults Using AI Companions Daily
Experts expect 30% of U.S. adults to use AI for companionship every day by 2040 — five times the 6% who did in 2025.

Our Analysis
How do we interpret these results
By 2040, the bottom quartile of experts believe that less than 16% of people will self-report using AI for companionship daily whereas the top quartile believe that more this figure will be more than 40%; the top decile of experts believe that more than 60% of people will use AI for companionship daily. While experts and superforecasters predict similarly, the general public predicts substantially less adoption by 2040: 20% vs experts’ 30%.

Rationale analysis
The main lines of reasoning driving the spread in estimates
Loneliness
Many high-forecast respondents project a substantial expansion of use, in large part due to increasing loneliness. One notes that “the U.S. Surgeon General declar[ed] loneliness an epidemic in 2023, with about half of U.S. adults experiencing measurable levels of loneliness.” A few low-forecast respondents emphasize lower saturation limits. One writes, “About a quarter of U.S. adults go to therapy. If that's the market size, then I expect AI to eventually saturate [at] that.”
Capabilities
Many high-forecast respondents believe AI capabilities are likely to improve dramatically, making companions more “sophisticated, emotionally intelligent, and capable of forming deeper connections with users,” and that “personalized AI companions that learn and adapt to individual users' preferences and needs will become more common.” Low-forecast respondents tend to argue that AI is unlikely to be able to replicate genuine human connection: “Nothing can replace real human interactions, and the vast majority of the population will be reluctant to have emotional interactions with AI.” One forecaster argues that “most people would find such companionship unfulfilling, perhaps even viewing reliance on it as a kind of failure.”
Technological integration
High-forecast respondents frequently cite integration with smartphone apps, wearable devices, and social media platforms as a likely driver of widespread use, even among those not searching for companionship. As one forecaster observed, “I have Grok in my car, Alexa in my kitchen, and Meta in my glasses and it's 2025. I do not use them for companionship, but I do miss them when not available.” Another emphasized that “ambient access through devices turns companionship into a series of micro-interactions throughout the day.” Low-forecast respondents often question whether the current technology can provide genuine companionship, with one arguing “it will not be a substitute for human interaction unless or until AIs achieve human levels of autonomy.”
Generational adoption patterns
Both sides acknowledge strong generational effects, but interpret implications differently. High-forecast respondents tend to see use among young adults (25% of 18-29 year-olds have tried AI companionship) as indicative of future mainstream adoption. One notes, “Young teens have much higher usage patterns for companionship than adults, hence giving some early indication of usage by adults in future years.” Another thinks the proportion “will increase rapidly as children grow to adulthood accepting these conversations as natural, having known interactive systems like Siri and Alexa for all of their conscious lives.” Some low-forecast respondents acknowledge youth adoption but emphasize resistance from older demographics, anticipating “generational resistance from many older adults” and that the “novelty will wear off.”
Regulatory and social acceptance
“Government regulation is unlikely,” is a common view among high-forecast respondents. Relatedly, they anticipate declining social stigma as AI companionship becomes normalized through integration with existing platforms. Several low-forecast respondents emphasize the potential for “persistent social/cultural resistance” that could lead to regulatory backlash. One notes, “Recent cases of suicides, possibly caused by AI companionship…may reduce trust and adoption. I assume that there will be more regulation limiting how people can/should use AI companion tools.”
Rationale examples
High-quality rationales from forecasters across the range
High-forecast respondents
Facebook growth and penetration of the United States adult population may be the best analogy for the potential scale and trajectory of Companion-AI. About 50% of the adult population used Facebook daily as of 2021 per Pew Research. Adult Facebook general usage peaked at 72% in 2015 per Pew research via a Gemini query.
Per this set of statistics, over 60% of people experience loneliness as a chronic condition in the US. https://www.discoveryaba.com/statistics/loneliness. People spend huge amounts of money attempting to alleviate this.
AI companion experience will be fundamentally different: likely multi-sensory (holographic/VR), capable of long-term memory, and indistinguishable from human interaction for many. The proportion of daily users may approach the current daily usage rate of major social media platforms.
Low-forecast respondents
Nothing can replace real human interactions, and the vast majority of the population will be reluctant to have emotional interactions with AI.
Alignment constraints, regulation, and social stigma will suppress widespread adoption in conservative or regulated contexts. Ethical debates over dependency, consent, and simulated intimacy are likely to trigger restrictions in schools, workplaces, and certain jurisdictions.
