Sports categories and how soccer works

How sports markets are organized on 4rho.

Categories follow data sources

The category list you see on the home page and in the navigation comes straight from upstream data sources — sports books and information providers — not from a list 4rho hand-picks. Categories appear and disappear as the underlying coverage changes.

Soccer is its own top-level category, not a sub-category of "Sports".

Beyond the top-level category (Sports, Crypto, Politics, …), each market also carries provider-supplied subcategory tags — things like ["Hockey"], ["Hourly", "BTC"], or ["US Elections", "Governor"]. These are surfaced on the market page so you can tell at a glance whether a "Sports" market is NHL or MLB without parsing the title.

One game can be many markets

Most sports markets are binary — two outcomes, YES or NO. A football moneyline is naturally binary: one team wins, the other loses. Spreads and totals are binary: cover or don't cover, over or under.

Soccer is the exception. A soccer match has three outcomes: home win, away win, or draw. We model this as three separate binary markets, all grouped under the same event so the page shows them together:

"Will the home team win?" — YES if they win, NO otherwise.
"Will the away team win?" — YES if they win, NO otherwise.
"Will the match end in a draw?" — YES if it's a draw, NO otherwise.

The three prices add up to roughly $1, just like in a single binary market. You can trade any combination — back the home team and hedge with a draw position, for example.

Spreads, totals, and props

Beyond the moneyline, you'll see:

Spread (SPR) — Will Team A cover the point spread?
Total / Over–Under (O/U) — Will the combined score go over the line?
Props — Player-specific or game-specific binary markets (e.g., "Will player X score 25+?").

All of these are presented as binary markets. The label tells you what the market is asking; the price tells you what the market thinks.

Liquidity varies by event

Marquee events have deep order books and tight spreads. Lesser-known events may have thin liquidity. When liquidity isn't sufficient to quote a fair price, 4rho shows RFQ instead of a number — see What "RFQ" means.

Where the team logos come from

Logos use ESPN's public CDN. If a logo doesn't load, the team initials display in its place — no third-party trackers, no surprises.
