The basics

Types of online gambling in the US

From point‑spreads to event contracts, these are the main ways Americans gamble online — each covered in depth across our hubs.

Sports betting

Moneylines, point spreads, totals, parlays and player props on every major US and global league.

Online casino

Real‑money slots, blackjack, roulette and live‑dealer tables in the seven regulated iGaming states.

Prediction markets

Buy Yes/No event contracts on sports, politics and the economy on CFTC‑regulated exchanges.

Sweepstakes casinos

Free‑to‑play social casinos that let you redeem Sweeps Coins for real cash prizes and gift cards.

Horse racing

Pari‑mutuel advance‑deposit wagering (ADW) on 500+ US and international tracks.

Poker & DFS

Regulated online poker in select states, plus daily fantasy sports in most of the country.

Background

A short history of US online gambling law

How the American market got here — the federal milestones that still shape where and how you can gamble online today.

1961 — The Federal Wire Act
Restricts interstate wagering “by wire,” the foundation of US betting law for the next half‑century.
1978 — Interstate Horseracing Act
Legalizes pari‑mutuel horse betting across state lines — still the reason no prediction market can offer racing.
1992 — PASPA
Effectively bans state‑sanctioned sports betting nationwide, with Nevada grandfathered in.
2006 — UIGEA
Targets the payment processing behind online gambling rather than players themselves.
2011 — DOJ Wire Act opinion
Limits the Wire Act to sports betting, opening the door to legal online casinos and lotteries; New Jersey, Delaware and Nevada launch iGaming in 2013.
2018 — Murphy v. NCAA
The Supreme Court strikes down PASPA, letting every state legalize sports betting — and dozens quickly do.
2020–21 — Kalshi & the CFTC
Kalshi wins designation as a CFTC‑regulated exchange, seeding the modern prediction‑market era.
2024–26 — Predictions & sweeps boom
Sports event contracts reach all 50 states via the CFTC, sweepstakes casinos surge, and new state restrictions arrive (such as California’s 2026 ban).
