Low-hold market scanner

Find tighter two-way markets before you size a hedge, promo, or line-shop decision.

Low Hold scans two-sided markets and surfaces where the combined implied probability is closest to fair. It is built for comparing price quality, not for treating every low-hold row as a recommendation.

What it does

What Low Hold helps you review

Ranks two-way markets by hold so users can spot prices that are closer to fair.

Supports practical workflows like hedging, promo conversion, and efficient line shopping.

Best fit

Who this tool is for

Markets and platforms

Coverage depends on supported books, markets, and user location

Two-sided sportsbook markets where Upside has enough book coverage to compare both sides.

Availability varies by league, event, sportsbook, and user location.

Upside scans 30+ sportsbooks, DFS apps, exchanges, and prediction markets across the product, but each tool has its own coverage rules and data availability.

Workflow

What to check before making your own decision

Sort by hold percentage

Start with the lowest-hold rows to find two-way markets where the combined implied probability is closest to fair. Low hold is a pricing signal, not an automatic play.

Review both sides of the market

Check which books provide the best price on each side and whether those prices are still live. One stale side can change the value of the full market.

Use the right calculator

Use the No-Vig Calculator for fair-price context, the Hedge Calculator for offsetting positions, and the Arbitrage Calculator if the hold turns negative.

Match the market to the use case

Low-hold rows can help with hedges, promos, and line shopping. They are not the same as guaranteed arbitrage, and the page keeps that distinction clear.

Before relying on the data

  • Are both sides of the market available at the listed books right now?
  • Is the row useful for a hedge, promo, or line-shopping decision rather than being treated as guaranteed profit?
  • Does the no-vig or hedge math still work after accounting for stake size and account limits?

Questions

Common Low Hold questions

What is the Low Hold tool?

The Low Hold tool compares both sides of supported sportsbook markets and ranks rows by how close the combined implied probability is to fair pricing.

Is low hold the same as arbitrage?

No. Low hold can be positive, near zero, or negative. Arbitrage requires negative hold, where opposing prices theoretically sum to less than 100 percent implied probability.

Who should use Low Hold?

Low Hold is most useful for adults who already understand line shopping, hedging, and promo conversion and want a faster way to identify efficient two-way markets.

Why does hold percentage matter?

Hold percentage shows how much margin is built into both sides of a market. Lower hold usually means the prices are closer to fair, which can make the market more useful for research.
