Live Betting Now Tops 52% of US Sports Wagers as Microbetting Health Alarms Grow

Live in-play betting has crossed the threshold of 50% of all US online sports wagers, driven by rapid product innovation from major sportsbooks, a World Cup that delivered an avalanche of event volume, and a structural shift in how American bettors engage with sport. New data also shows that live bettors spend nearly twice as much each month as pre-match customers, a finding that is fuelling intense debate about the mental health risks of microbetting products designed to keep users wagering on every pitch, pass, and possession.

How fast is live betting growing in the United States?

Live betting has moved from a niche feature to the dominant format of US online sports wagering in under five years. Research from Optimove found that 52% of all US online sports wagers placed in 2024 were in-play bets, up sharply from the low single-digit percentages recorded when states began legalising mobile sports betting in 2018 and 2019.

DraftKings confirmed at its Q1 2025 earnings call that live betting had exceeded 50% of its overall sports betting handle, the first time the company had publicly confirmed that milestone. CEO Jason Robins described the company's in-play capabilities as a competitive moat: "We are the leader right now and have by far the best offering," he said, citing over 90% uptime in the company's core live markets.

What is microbetting and why does it matter?

Microbetting is a subset of live wagering that allows users to bet on the outcome of individual, granular moments within a game: the next pitch in baseball, the next serve in tennis, the next drive in American football. Unlike traditional live betting, which operates on match or half-level outcomes, microbets resolve in seconds or minutes, compressing the gambling cycle to a pace that critics compare to slot machine play.

DraftKings has pushed aggressively into microbetting product design. Its Moonshot product, launched for Major League Baseball, functions as a slot-style wager: users place a single bet that can build in value across multiple game events, with multiplier-based payouts. The product blends sports betting with mechanics traditionally associated with electronic gaming machines.

How much do live bettors spend compared to pre-match bettors?

The spending gap is large and growing. Optimove's research found that live bettors spend an average of $1,583.90 per month on sports wagering, compared with $846.20 for pre-match bettors. That is an 87% premium, which explains why sportsbooks are competing intensely to drive customers toward in-play products and why Genius Sports has built a substantial business on supplying the data and pricing infrastructure that makes microbetting possible at scale.

Genius Sports reported $126.1 million in commissions from live microbetting during 2025, representing approximately 19% of the company's total annual revenue. That figure came directly from an amended complaint in a federal lawsuit, which used Genius Sports' own financial disclosures to illustrate the commercial stakes of the microbetting market.

What are the health and regulatory concerns around microbetting?

Research published by the Campaign for Fairer Gambling found that 78% of microbettors meet the standard screening criteria for problem gambling, a rate far above that found in the general sports betting population. The same research identified patterns of emotional dysregulation, impulsive decision-making, anxiety, depression, and substance co-morbidity among heavy microbettors.

CFG Director Brianne Doura-Schawohl described the findings in stark terms: "Microbetting creates an urgent mental health threat demanding immediate action," she said, pointing to the deliberate targeting of younger audiences through aggressive digital marketing by major operators.

A separate survey found that 43% of Americans believe sports betting is harmful to society overall, a figure that has risen in line with the expansion of mobile betting access and the visibility of sportsbook advertising across major professional sports.

Who is suing over microbetting and what are the claims?

Plaintiffs Christopher Sage and Terry Thompson have filed an amended complaint in federal court against the NFL, DraftKings, FanDuel, and Genius Sports. Their lawyers allege that microbetting is deliberately designed with addictive mechanics analogous to electronic slot machines, and that Genius Sports received $126.1 million in commissions from the product in 2025 while the defendants promoted it without adequate consumer safeguards.

The lawsuit also alleges that the involvement of sports leagues in licensing data to companies that build and profit from microbetting products creates a conflict of interest that undermines the leagues' stated commitments to responsible gambling. The case is being closely watched by regulators and operators across the industry, as its outcome could establish whether sportsbooks face a legal duty of care toward customers who develop gambling disorders through products the companies designed and marketed.

How does US live betting compare to mature European markets?

Market	Live Betting Share	Notes
United States	52%	Crossed 50% threshold in 2024; mobile betting legal since 2018
Greece	70%	Mature regulated market; live betting deeply embedded in culture
Italy	57%	Long-established online market; live betting share growing steadily

The comparison with Europe is instructive. Greece and Italy represent what a maturing US market could look like in five to ten years if current growth trajectories continue and regulatory guardrails remain light. Both jurisdictions have also struggled with elevated problem gambling rates, a pattern that health researchers cite as a cautionary data point for US policymakers considering how to regulate microbetting products specifically.

What do sportsbooks say about responsible gambling in live betting?

DraftKings and FanDuel both point to their voluntary responsible gambling programmes, deposit limits, session time limits, and self-exclusion tools as evidence that they are addressing harm proactively. Both companies are signatories to the American Gaming Association's responsible marketing code and contribute to the National Council on Problem Gambling through industry funding arrangements.

Critics argue that voluntary measures are structurally insufficient when the core product is designed to maximise engagement and spending. The federal lawsuit, if it proceeds to trial, may force a judicial examination of whether sportsbooks owe a specific duty of care to customers who develop gambling disorders through microbetting products. The outcome of that case could reshape product design standards across the entire industry.
