Our Mission

Plain-language information on legal online horse betting in the US.

Fiona Hartwell has spent eight years digging into pari-mutuel wagering rules, Advance Deposit Wagering licenses, and state racing commission filings. This site reflects that work. It covers how to bet on horses online from the ground up — legal framework, platforms, bet types, taxes, and more.

What does Fiona actually do before publishing?

Every platform mentioned on this site is cross-checked against state racing commission records. If a license isn't verifiable, the operator doesn't get recommended. Period. Bonus and promo figures are pulled directly from operator terms, not press releases.

Takeout rates, pari-mutuel math, and tax rules come from primary sources — the Interstate Horseracing Act of 1978 (USDA AMS) and IRS Topic 419 on gambling income. If a number isn't sourced, it isn't published.

Who is this site built for?

Casual bettors who want to open a first ADW account. Serious players comparing the best licensed ADW platforms for online horse betting. Anyone who needs a plain-English breakdown of horse racing bet types like exactas and trifectas or wants to understand how pari-mutuel pools and takeout work.

State legality is a constant theme. ADW rules vary widely. The ADW state-by-state legal guide is updated whenever commission records change.

Editorial standards

No manufactured odds. No invented license numbers. No affiliate relationships that change editorial verdicts. Facts are cited; gaps are labeled as such. Responsible gambling resources — including the National Council on Problem Gambling — are linked throughout the site.

Must be 18+ (21+ in some jurisdictions) to open an ADW account. Gambling problem? Call 1-800-522-4700.
