What the estimates tell you
Model-based research
For MLB, Mongoose aggregates simulated outcomes into probabilities and player projections. Those estimates depend on the inputs and assumptions of the model. Read the methodology and worked examples before interpreting an edge.
Odds-scanning research
OddsJam describes scanning sportsbook prices to surface Positive EV bets. Its product page also lists Arbitrage, Parlay Builder and Promo Converter. Check the current plan for the specific markets and functionality you need.
A model probability and a market-derived estimate are both estimates. Neither is the true probability by definition. Compare either with the price you can actually place, and keep the event, market and timestamp consistent. See the EV calculator for the relationship between odds and expected return.
Pricing and access
Mongoose Bets costs $39/month or $350/year. Check our subscription page for plan details and current trial terms. A limited public preview and the free calculators let you explore before choosing a subscription.
Use OddsJam's subscription page for its current price and billing terms. Compare the full renewal cost and included tools, not just an introductory offer. This page does not assume that either subscription will earn back its cost.
How to compare them for your needs
- Choose the leagues, markets and sportsbooks you actually use, then check coverage in each product.
- Inspect how a probability or edge is defined and when the underlying inputs were updated.
- Distinguish the Mongoose manual arbitrage calculator from a service that finds opportunities for you.
- Evaluate results with predictions recorded before games and a stated sample period. We have not conducted a matched performance study of these two products.
Frequently asked questions
How does Mongoose Bets differ from OddsJam?+
Mongoose Bets publishes model-based sports projections, including 2,500 Monte Carlo simulations per MLB game. OddsJam advertises an odds-scanning Positive EV tool alongside arbitrage and parlay tools. These are different ways to research bets; neither establishes that a particular bet will win.
How much does OddsJam cost?+
Check the official OddsJam subscription page for the current price, billing interval, included tools and renewal terms. We do not quote a fixed competitor price here because plans and promotions can change.
Does Mongoose Bets offer an arbitrage scanner?+
The public Mongoose Bets arbitrage tool is a manual calculator. You enter odds to calculate stake allocations; live opportunity scanning is not currently available. OddsJam lists arbitrage among its betting tools. Confirm that any scanner supports the books and markets you can use.
Which tool is more accurate?+
This comparison does not establish a performance winner. That would require predictions recorded before events, matching markets and timestamps, and a disclosed evaluation period. Model probabilities and market estimates can both be wrong; a closing-line comparison alone does not prove profitability.
Should I subscribe to both?+
First check whether each tool answers a distinct question for your betting process. Compare available markets, data freshness and total subscription cost. Agreement between two estimates is not independent confirmation if they share inputs, and neither subscription guarantees a positive return.
