Behind the prices

Every line on SonicBet follows the same documented process, from the choice of topic to the date shown under the byline. This page sets it out, including the parts done by software.

How do we choose what to write about?

Topics come from search demand data: the questions people actually type about odds, such as how to remove the vig or what reverse line movement means. We pick the question first, then the market and the prices that answer it best.

Where do the numbers come from?

From primary sources, not from tipster sites. For odds and markets that usually means:

• Bookmaker prices and house rules. Prices as posted by the book, and the book's own terms on settlement, void bets and player props. A price is always reported with the book that posted it.
• League and official data. League rules and official reporting deadlines, such as injury and availability reports, and official results.
• Regulators. State and national regulators' rules and published data where a line touches on what may be offered or how a market is supervised.
• Published research. Academic papers and published data sets on market efficiency, closing lines and betting splits, cited by name.

Each line written under this process ends with a list headed "Price and data sources". Older lines carry no such list and stay up as first posted.

What about the match bulletins?

The match bulletins on the home page are drafted from public data feeds: fixtures from TheSportsDB, and prices and finals from ESPN's public scoreboard, as posted by the book it lists. Prices are reported as posted, a late feed is marked as late, and times are in UTC.

How are lines drafted?

Drafts are written with the help of AI writing tools, working to a brief and to the sources gathered for that line. The draft may only state what the sources support. Every conversion, margin and CLV figure is worked through so anyone can repeat it.

What is checked before a line goes up?

Automated checks run on every line before publication. They look for a source behind each claim, test that links work, and compare the figures and dates in the line against its sources. A line that fails is held back until it passes. We do not claim human expert review, and we do not claim to have placed the bets we describe.

How do corrections work?

Spot a wrong price, score or date? Tell us through our contact form. When a fact is wrong we fix it, and a line that changes in substance shows an Updated date under its byline.

How do updates work?

Books change their rules and leagues change their deadlines. When a source we relied on changes, we update the line and the date with it.

What we do not do

We do not tip outcomes, we do not sell picks and we do not promise profit. A commission never changes what a line says about a price.
