Babylon Bets: Market consensus and a model second opinion for prediction-market traders.
Babylon Bets is a multi-sport research tool for prediction-market traders. For each game it shows the market's consensus price — the number you're trading against — next to a clearly-labeled model second opinion, and tracks how the model has done against the market using closing-line value (CLV) and Brier scores, across MLB, NBA, NHL, NFL, college sports, soccer, golf, tennis, UFC, and motorsports. It is built for exchanges like Kalshi — where you trade against other participants, not a house — and it is a research tool, not a sportsbook.

Frequently asked questions
- What is Babylon Bets?
- Babylon Bets is a multi-sport research tool for prediction-market traders. For each game it shows the market's consensus price next to a model second opinion, and tracks how the model has done against the market (closing-line value and Brier) across MLB, NBA, NHL, NFL, college sports, soccer, golf, tennis, UFC, and motorsports.
- Does Babylon Bets beat the market?
- Not reliably, and the site does not assume it does. The model is a second opinion shown next to the market's price; its record against the market — closing-line value and Brier — is shown for each sport so you can judge it yourself. The aim is context for your own decision, not a guarantee of winning picks.
- Is Babylon Bets a sportsbook?
- No. Babylon Bets is a research tool, not a sportsbook and not a place to place wagers. It is built for traders on prediction-market exchanges such as Kalshi, where you trade against other participants rather than against a house.
- What sports does Babylon Bets cover?
- MLB, NBA, NHL, NFL, college football and basketball, soccer (including the EPL, La Liga, Serie A, Bundesliga, MLS, the Champions League and the World Cup), golf, tennis, UFC, and motorsports (Formula 1 and NASCAR).
- What is closing-line value (CLV)?
- Closing-line value measures how a position's entry price compares with the market's closing price. Consistently beating the close is a leading indicator of edge, and Babylon Bets uses CLV as the referee for whether a model is actually adding value.
