FanDuel has widened access to AceAI, its artificial intelligence betting assistant, extending the tool to almost every regulated market in the country. The chatbot now reaches customers in every state except Connecticut and supports wagers on the NFL, NBA, MLB, NHL, college football, college basketball and soccer.
The expansion marks a sharp change from AceAI’s original test run. FanDuel introduced the online sports betting assistant in March 2025, limiting access to roughly 1% of its customer base and, at that stage, covering only the NFL and NBA.
From 1% to nearly everywhere: AceAI’s growth in numbers
AceAI has processed more than 268,000 customer queries since its debut, FanDuel said, describing the wider release as an ongoing step rather than a finished product. The company plans to keep testing new features as adoption grows, although no mention of it expanding to the FanDuel Casino side of the app.
Inside AceAI’s conversational betting experience
AceAI sits within the FanDuel Sportsbook app and answers typed or spoken questions. It remembers earlier messages in a conversation, so follow-ups don’t require restating context.
A customer might ask about a pitcher’s strikeout total across recent starts, then ask AceAI to build a parlay around that performance — pairing the pitcher’s next outing with a wager on total runs scored, all in the same exchange. Many customers also use AceAI earlier in the process, before they’ve settled on a bet, to check stats and validate an idea rather than build a slip outright.
Rebecca Jee, FanDuel’s product director, said customers often “go back and forth with Ace a lot” before settling on a bet. Even when a response isn’t exactly what a customer meant, she said, the tool adapts — and that exchange often leads directly to a bet being added to the slip.
Balancing AI innovation with responsible gaming
A team of roughly 20 engineers, AI specialists, product managers and designers built AceAI alongside separate security, legal and compliance staff. The company combined several large language models with its wagering systems, Jee said, and pulls player and team data from numberFire, FanDuel’s analytics platform.
FanDuel says AceAI is the first tool of its kind in the regulated US sportsbook industry.
Responsible Gaming safeguards are built directly into the assistant. Only the customer can add a selection to their bet slip, and if a message suggests risky behavior — such as asking how to recover previous losses — AceAI responds with pre-approved support resources instead of betting suggestions. Flagged conversations can be escalated to Responsible Gaming staff rather than left to the AI alone.
“You definitely don’t want to rely solely on the LLM, especially in a space like this,” Jee said in a FanDuel news release.
Some industry observers have questioned whether such tools make it harder for struggling bettors to step away. FanDuel points to its screening safeguards as a response, though the broader debate over AI’s role in gambling hasn’t gone away.
AI betting tools are becoming and industry standard
The expansion comes as rival sportsbooks lean further into AI. DraftKings has said AI now touches everything from customer support to promotional pricing, calling it central to daily operations.
FanDuel’s parent, Flutter Entertainment, has taken a similar approach abroad with Sportsbet, its Australian brand, building a comparable assistant, Apollo, reportedly sharing code and lessons from AceAI’s first year.
The push reflects how competitive the US sportsbook market has become: FanDuel and DraftKings together account for most national betting handle, and roughly 27% of Americans now hold an active online betting account, per a spring survey from the Siena Research Institute — up sharply from prior years.
FanDuel maintains AceAI is meant to inform decisions, not encourage extra bets, and hasn’t said whether the assistant will eventually become the main way customers navigate its app.
