Arbitrage and +EV alerts for US sportsbooks

The books don't always agree. Plus Side tells you when.

Plus Side scans US sportsbooks every few minutes and posts arbitrage and +EV alerts to a private Discord. Each alert has the bets, the stakes, and the worst price each bet can take before the edge is gone.

21+. Bet only where it's legal. Plus Side doesn't take bets.

How it works

Three steps, and you only do the last one

  1. Step 1

    We scan the books

    Plus Side checks pregame lines at US sportsbooks every few minutes, all day.

  2. Step 2

    The alert lands in Discord

    When prices line up, an alert posts with the bets, the stakes for a $100 total, and how old the prices are.

  3. Step 3

    You place the bets

    You bet at your own sportsbooks. The break-even price tells you whether a bet is still worth placing.

What's in an alert

Everything you need to place the bet, and nothing else

Bears +145 at one book and Lions −130 at another add up to an implied 97.34%. Anything under 100% means you can bet both sides and get back more than you staked.

Two kinds of alert

Arbitrage for several books. +EV for just one.

ARB

Arbitrage

Bet every side of a game at different books. The stakes are set so you get the same return whichever side wins.

Best for
Bettors with accounts at several books, in states such as New Jersey, New York and Pennsylvania.
Watch for
Prices move fast. Place both bets quickly and check each against its break-even price.
+EV

Positive expected value

One bet at one book, priced better than the fair price worked out from sharp books. Any single bet can lose. The edge shows up over many bets.

Best for
Anyone with a sportsbook account, including single-book states such as Florida.
Watch for
Losing streaks are normal. Size your bets so you can ride them out.

Pricing

One plan. 50 founding seats.

When lots of people bet the same price, the line moves and sportsbooks notice. Every extra member makes each alert worth a little less, so Plus Side caps the seats. When they're all taken, sign-ups close until one opens.

There's no free trial. The #results channel is free instead, and you can cancel any time.

The honest part

What can go wrong

Arbitrage takes most of the luck out of betting. It doesn't take out all of the risk.

Prices move

A line can change between your first and second bet. Check the break-even price before the second one, and know what you'll do if it's gone.

Books limit winners

Sportsbooks can cut the stakes of accounts that win or bet both sides. It's the main reason arbitrage bettors stop. Spreading bets across books helps.

Rules differ

Books can settle the same game differently after overtime, a postponement or an obvious pricing error. Check both books' rules before you bet.

FAQ

Questions

Do you place bets for me?

No. Plus Side posts alerts. You place every bet yourself, at sportsbooks where you have an account.

Is this legal?

Plus Side is an information service and doesn't take bets. You're responsible for betting only where it's legal for you, and only at sportsbooks licensed in your state. Each sportsbook's own terms apply to every bet you place.

Which states does it work in?

Arbitrage needs accounts at two or more books, so it works best in states with many licensed sportsbooks, such as New Jersey, New York and Pennsylvania. +EV alerts need only one book, so they're useful in single-book states such as Florida too.

How much money do I need?

Alerts are sized for a $100 total, and you can scale the stakes up or down. Arbitrage needs money at several books at once, so most people keep a balance at each. Margins are usually small, so returns grow with the amount you stake.

How fast are the alerts?

Alerts post as soon as a scan finds them. The prices come from an odds data provider that refreshes about once a minute, so a quote can be up to 2 minutes old when you see it. Every alert shows its age.

Will sportsbooks limit my account?

They might. Books can cut stakes for accounts that win often or bet both sides of a game, and we can't stop that. Spreading your bets across books and mixing in +EV bets may help.

Is there a free trial?

No. The #results channel is free and shows every past alert after its game starts, so you can judge the service before you pay.

How do I cancel?

Any time, from your Whop account. Whop removes your access to the member channels when your subscription ends.
