What exactly is a "pick" in sports betting?

A pick is a prediction — made by an analyst, a handicapper, or a bettor themselves — on the outcome of a sporting event. That prediction can cover the outright winner, the point spread, the over/under total, or any other available wager type. Start with the full breakdown at What Are Sports Betting Picks? A Plain-Language Definition.

What does pick'em (PK) mean?

A pick'em, abbreviated PK on a bet slip, is a game where neither team is favored — the point spread is zero and both sides carry standard -110 odds. For everything on how that pricing works in practice, see Pick'em (PK) Explained — Zero Spread, Even Odds, -110 Vig.

Quick-reference glossary of picks terms

Handicapper
A professional who reviews facts, figures, and statistics before releasing picks, with the goal of finding a betting edge. See What Is a Sports Handicapper? How Pros Build Their Picks for how that research process actually unfolds.
Vig / Juice
The sportsbook's built-in commission. Standard spread and pick'em bets are priced at -110, meaning a bettor risks $110 to win $100, implying a break-even win rate of roughly 52.4%. The full cost breakdown is at Vig and Juice in Sports Betting — Why -110 Costs You 2.4%.
Moneyline
A straight bet on which team wins outright, with no spread applied. It's the primary bet type in pick'em games.
Spread bet
A wager on the margin of victory. The favorite must win by more than the spread; the underdog must lose by less than the spread (or win outright).
Parlay
A single wager combining two or more picks. Every leg must win for the bettor to collect — one loss sinks the whole ticket.
Tout / Paid-pick service
A handicapper or platform that sells picks for a fee. Packages can reach $899 with no performance guarantee. For help separating legitimate services from red flags, see Are Paid Sports Betting Picks Worth the Cost?
Free picks
Expert predictions published at no charge. Sites such as Covers.com and OddsChecker release free picks anywhere from two to three days before kickoff (NFL, college football) to the morning or afternoon of game day (NBA, MLB, NHL).

Geolocation
Technology every legal sportsbook app uses to verify a bettor is physically inside a permitted state at the moment a wager is placed. Your home-state address is irrelevant; only your physical location at bet time counts.
PASPA
The Professional and Amateur Sports Protection Act — the federal ban on single-game wagering struck down by the Supreme Court in May 2018, opening legalization to all states.
Sportsbook / Bookmaker
The licensed entity that accepts and pays out wagers. Only state-licensed sportsbooks provide regulatory recourse; offshore and unlicensed operators operate outside consumer-protection frameworks.

Where can I check whether sports betting is legal in my state?

As of mid-2026, 39 states plus Washington D.C. and Puerto Rico have authorized legal sports wagering, while 11 states have not. Most legal states set the minimum age at 21, though a handful permit 18+. The RG.org regulatory tracker lists each state's current status, regulator, and tax structure.
