Gallup Poll Records Sharp Drop in U.S. Gambling Participation as Prediction Markets Blur Survey Lines
TL;DR — Gallup’s poll shows U.S. gambling participation at 45%, down from 64% in 2016, with lottery and casino play sharply lower and sports betting at 7%. Online surveys and prediction market data reveal higher engagement, pointing to methodology and definitional gaps. Traditional metrics increasingly miss modern betting forms.
SCCG Take — Survey limitations risk distorting market size estimates for operators and complicating regulatory oversight. Updated polling frameworks are required to align data with actual participation across betting and derivatives.
A new Gallup telephone poll finds that 45% of U.S. adults engaged in some form of gambling over the past 12 months. That figure is down from 64% in 2016, with state lottery participation falling from 49% to 31% and in-person casino gambling dropping from 26% to 14%. Sports betting registered at just 7%, below the 10% recorded in 2016 despite the nationwide expansion of legal books since the 2018 Supreme Court ruling.
Other surveys tell a different story. The Siena Research Institute reported 27% of Americans hold an active online sportsbook account. Gallup’s own parallel online poll produced a higher overall participation rate of 53%, with sports betting at 21% versus 15% by telephone. A Pew Research Center online survey aligned closer to the 22% sports betting mark.
Divergent Data on Prediction Market Activity
Gallup recorded only 2% of respondents placing bets on non-athletic events in prediction markets. Yet sports dominate actual volume: Ticker Tracker data show 83% of Kalshi’s $41.2 billion in July trading volume was sports-related, while Polymarket’s U.S. platform reached 97.7% sports concentration. Separate surveys capture far higher engagement, with Siena at 15% for sports prediction markets and Navigator Research at 14% overall usage, rising to 29% among Gen Z.
Defining the Measurement Gap
The Gallup results, as reported by Gambling Insider, highlight real declines in traditional gambling but also expose clear limitations in telephone-based methods that may undercount activity due to stigma or definitional confusion over what counts as betting versus trading. Operators and regulators cannot rely on these snapshots alone to gauge market penetration or consumer behavior as prediction markets scale. Future polling must address these overlaps or risk guiding decisions on flawed premises.

Traditional polling is broken for gambling: phone surveys miss digital bettors, misdefinitions blur markets, and operators lose sight of real scale.
We've seen this movie before—bad data drives bad decisions. When Gallup shows 7% sports betting but parallel online surveys hit 21%, that's not a rounding error, it's a measurement crisis. Operators building forecasts on telephone polls are flying blind, and regulators using outdated snapshots will misjudge both market size and risk exposure as prediction markets explode.
- Gallup phone poll: 45% participation, 7% sports betting; online surveys show 21%–27%, revealing severe methodology bias
- Prediction markets underreported at 2% despite billions in volume and 14%–29% usage in digital-native surveys
- Lottery and casino declines real, but survey design misses platform shift and stigma effects among younger cohorts
SCCG angle: SCCG connects operators to the research firms, data providers, and compliance advisors who can close this gap—building audience models that reflect actual digital behavior, not outdated telephone samples. We've guided partners through market-entry decisions in 38 jurisdictions; getting the denominator right is step one.
