What is Sports Betting?
Sports betting is wagering money on the outcome of a sporting event. You pick a side, place a bet, and if you're right you win money. If you're wrong, you lose your wager.
There are three main types of bets you'll see on FadeReport — and on any sportsbook:
Moneyline
A straight-up bet on who wins the game. No point spread involved — just pick the winner.
Point Spread
A bet where one team is given a handicap to level the playing field. The favorite has to win by more than the spread; the underdog just has to lose by less (or win outright).
Over/Under (Total)
A bet on the combined total score of both teams. You bet whether the final score will go over or under a set number.
How Betting Lines Work
Betting lines can look confusing at first. Here's how to decode them.
Moneyline
Example
Lakers -180 vs Celtics +155
The minus sign (-) means the Lakers are the favorite. You'd have to bet $180 to win $100.
The plus sign (+) means the Celtics are the underdog. A $100 bet wins you $155.
Point Spread
Example
Lakers -6.5 (-110) vs Celtics +6.5 (-110)
If you bet the Lakers -6.5, they need to win by 7 or more for you to win.
If you bet the Celtics +6.5, they can lose by up to 6 and you still win.
The (-110) is the juice — you bet $110 to win $100. That's the sportsbook's cut.
Over/Under
Example
Total: 224.5 o/u (-110)
If the combined final score is 225 or more, the Over wins.
If it's 224 or less, the Under wins.
Both sides are usually -110, meaning the sportsbook takes equal juice on each side.
The juice (or vig) is how sportsbooks make money. At -110, you're paying a small premium on every bet. Sharp bettors look for lines with reduced juice or find spots where the line is mispriced.
What Are Betting Splits?
Betting splits are data released by sportsbooks showing how bettors are wagering on each side of a game. There are two numbers that matter:
% of Bets (Ticket Count)
The percentage of total individual wagers placed on each side. This represents the number of people betting, not the dollar amount.
% of Money
The percentage of total dollar volume wagered on each side. This shows where the actual money is going — which is more important than the number of bets.
Example
Duke vs UNC — Spread
% of Bets: Duke 68% — UNC 32%
% of Money: Duke 29% — UNC 71%
Most people are betting Duke — but most of the money is on UNC. That gap is the signal.
What is Sharp Money?
Not all bettors are equal. The betting market has two types of participants:
The Public
Casual bettors who wager on popular teams, favorites, and marquee matchups — often based on emotion, brand recognition, or TV exposure rather than analysis. They make up the majority of ticket volume.
Sharps (Sharp Money)
Professional or sophisticated bettors who wager large amounts based on data, models, and market analysis. They're a small percentage of bettors but move a disproportionate amount of money. Sportsbooks track their action closely and move lines in response.
When sharp money hits a side, the line moves — even if the majority of tickets are on the other side. That's reverse line movement, and it's one of the most reliable signals in sports betting.
Sharp bettors don't win every game. But they win at a higher rate than the public over time, and they consistently beat the closing line.
How to Read Betting Splits
Now that you understand what splits are and who the sharps are, here's how to put it together.
The key metric is divergence — the gap between % of money and % of bets on the same side. A large divergence means a small number of large bettors (sharps) are heavily on one side while the public bets the other way.
Real signal example
% of Bets: Team A 74% — Team B 26%
% of Money: Team A 22% — Team B 78%
Divergence on Team B: 78% money − 26% bets = +52 points
🔥 Tier 1 Strong Sharp Signal — sharp money is heavily on Team B despite the public loading up on Team A.
Tier 1 (20+ point divergence): Strong sharp signal. A meaningful gap between where the money is and where the bets are.
Tier 2 (10–19 point divergence): Lean sharp. Worth watching but less definitive.
Splits are one tool, not a guarantee. Sharp bettors are right more often than the public — but not always. Use this data as context alongside your own research.
Sharp Money Glossary
Fade the Public
Betting against the majority of casual bettors. The public tends to bet on popular teams regardless of value — sharps exploit this by taking the other side.
Reverse Line Movement
When a betting line moves against the direction of public betting. If 70% of bets are on the favorite but the line drops, sharp money came in on the underdog.
Steam Move
A sudden wave of sharp money hitting a line across multiple sportsbooks simultaneously, causing fast, coordinated line movement.
Closing Line Value (CLV)
How good your bet was relative to the final line at game time. Beating the closing line consistently is the best indicator of long-term betting skill.
Juice / Vig
The sportsbook's commission. At -110, you bet $110 to win $100. The extra $10 is the vig — how sportsbooks profit regardless of outcome.
Opening Line
The initial line set by the sportsbook. Lines move from open to close based on betting action, injuries, and sharp money.
Ticket Count
The number of individual bets placed on each side. High ticket count on one side usually means public money — not necessarily where the value is.
How FadeReport Works
FadeReport pulls real sportsbook betting splits every hour and runs them through a sharp money detection algorithm. We calculate the divergence between % of money and % of bets for every game and surface the signals automatically.
Tier 1 — Strong Sharp Signal 🔥
20+ point divergence. The strongest signals — where sharp money is clearly separated from public betting.
Tier 2 — Lean Sharp Signal ⚠️
10–19 point divergence. Worth watching, but less definitive than Tier 1.
We also generate AI analysis for every Tier 1 signal — pulling team records, recent results, and game context to explain why the sharp money makes sense.
FadeReport is a data tool. We show you where the money is going — what you do with it is up to you.
