View on Kalshi ↗ Reading the board
How to read Yes and No prices
The Yes figure is the latest usable Yes price in the public record. A 64 cent Yes price means that the market is trading that outcome around 0.64. It is a market signal, not an official forecast or a probability calculated by CalifGym.
Best bid is the highest displayed buying price. Best ask is the lowest displayed selling price. The spread is the gap between them. A wider gap can indicate a thinner order book or less agreement between current buyers and sellers.
One board, several sports
Sports prediction markets across football, basketball and hockey
Sports Market Pulse gathers a current selection of open sports contracts instead of limiting the page to one league. Choose All sports for a broad view, or narrow the board to a competition such as the Premier League, Champions League, NBA, WNBA, NFL or NHL.
The mix changes with the sports calendar. Match markets are common during active seasons, while championship, qualification, award and player markets may remain open for longer periods.
Football and soccer markets
Football markets may cover match results, league titles, tournament qualification, transfers, awards and season outcomes. Premier League and Champions League filters are available when matching records are open.
Basketball markets
Basketball markets can follow NBA and WNBA games, conference races, championship outcomes, player awards and other season questions published by the source platforms.
Hockey markets
Hockey markets may include NHL games, playoff qualification, conference winners and Stanley Cup outcomes. Availability depends on the current public source catalogue.
Other sports markets
The All sports filter can also surface American football and other active sports categories. A sport appears only when an external source provides a valid open record.
Sports market terminology
Prices, spreads, volume and liquidity explained
Each card keeps the market question beside its price and activity fields. Reading those fields together gives more context than reading the Yes price alone.
Polymarket and Kalshi do not report every field in the same unit. The labels below explain what CalifGym displays and where comparisons require care.
| Field | What it means | How to read it carefully |
|---|---|---|
| Market question | The event or outcome that the contract will resolve. | Read the exact wording and check the source rules before interpreting the price. |
| Yes price | The displayed contract price for the Yes outcome, converted to cents. | It reflects current market activity. CalifGym does not calculate or certify it as a probability. |
| No price | The complementary displayed value for the No outcome. | It helps show the opposite side of the question, but fees and order book conditions are not included here. |
| Best bid | The highest buying price available in the public source record. | A bid is an order book value, not proof that a trade will occur at that price. |
| Best ask | The lowest selling price available in the public source record. | Compare it with the bid to see the current gap between buyers and sellers. |
| Spread | The difference between the best ask and best bid. | A wider spread can be a sign of a thinner or less active market. |
| 24h volume | Activity reported by the source during the previous 24 hours. | Polymarket displays dollar volume. Kalshi displays contract volume, so the values should not be ranked as one unit. |
| Liquidity | A source field describing available market depth or funds. | Liquidity methods can differ by platform and do not guarantee an easy transaction. |
| Price move | The available one-day or previous-price change from the source record. | A short move shows recent direction, not the reason for the change or the final outcome. |
Keep the units separate
Volume and liquidity are not identical
Polymarket supplies dollar-denominated 24-hour volume and liquidity. Kalshi supplies 24-hour contract volume and a separate dollar liquidity value. The cards keep those units visible because ranking them as if they were the same number would be misleading.
Price, volume and liquidity only describe activity inside the named external market. They do not replace official schedules, league statistics, reporting or independent analysis.
Movement and context
Why sports prediction market prices move
A sports market price can change when new information reaches traders. Team news, injuries, starting lineups, schedule changes, official announcements and tournament results can all affect the orders visible on a source platform.
Trading activity also matters. A price may move because a small number of orders entered a thin market, not because the underlying event became certain. Check the bid, ask, spread, volume and update time before treating a move as meaningful.
For match facts, use an official league or team source. Sports Market Pulse is useful for observing market activity, but it is not a replacement for confirmed scores, schedules or team reporting.
Source and update method
Polymarket sports markets and Kalshi sports markets
For Polymarket, CalifGym requests active events through the public Gamma API. The All sports view checks sports metadata, while individual filters request the relevant sports tag. For Kalshi, the All sports view reads open events in the Sports category. Competition filters use the public series catalogue before requesting matching open markets through the Trade API.
The board selects current records from each source and keeps their activity units separate. It does not combine Polymarket dollar volume with Kalshi contract volume to create a false cross-platform ranking.
Each successful response is cached for five minutes and kept as a last known good copy. If a source is temporarily unavailable, the page can continue to show the most recent successful update with a stale-data notice. External buttons pass through fixed CalifGym routes that can only reach the named source domain.
| Source | Discovery method | Price fields | Activity fields | CalifGym use |
|---|---|---|---|---|
| Polymarket | Sports tag and active event query | Outcome price, best bid, best ask | Dollar volume and dollar liquidity | Read-only cards with source link |
| Kalshi | Sports series, competition match and open market query | Last Yes price, Yes bid, Yes ask | Contract volume and dollar liquidity | Read-only cards with source link |
Use the data with context
How to compare sports market data responsibly
Start with the full market question, then note the source and update time. Compare the Yes price with the best bid and best ask. If the spread is wide or recent volume is low, the headline price may offer limited information about current agreement.
Next, check official sports sources for the event date, lineup, injury status and result. A prediction market resolves under its own published rules, which may not match the shorthand used in a news headline or a fan discussion.
Sports Market Pulse has no account connection, wallet, deposit form or order button. CalifGym presents public data for research and sports analysis. It does not recommend a trade, wager or financial decision.
Sports market data FAQ
Questions about sources, prices and limits
What is Sports Market Pulse?
Sports Market Pulse is a read-only view of current public sports markets from Polymarket and Kalshi. CalifGym formats selected open records into one consistent card layout.
What does the Yes price mean?
The Yes price is the latest displayed price for the Yes outcome, expressed here as cents and as a percentage-style market signal. It is not an official probability.
What are best bid and best ask?
Best bid is the highest displayed buying price in the source data. Best ask is the lowest displayed selling price. The difference is the spread.
Why is volume shown differently for Polymarket and Kalshi?
The public sources use different units. Polymarket reports dollar-denominated market volume. Kalshi reports contract volume and a separate dollar liquidity field. CalifGym labels each value instead of treating them as interchangeable.
Which sports markets can appear?
The All sports view can include football and soccer, basketball, hockey, American football and other sports when Polymarket or Kalshi lists an open market. The available mix changes with the sports calendar and the source catalogue.
Are sports market prices the same as betting odds?
No. These are contract prices from prediction market platforms. Betting odds use a different product structure and may include a bookmaker margin. Neither format guarantees an outcome.
How often does Sports Market Pulse update?
The open page checks for fresh public data every five minutes. A source controls when its records change, and CalifGym may show a clearly marked last known good copy during a temporary source outage.
Why did a sports market disappear?
A market can close, settle, pause orders or stop appearing in a source feed. The board focuses on current open records, so it is not a permanent archive of every contract.
Can I buy or sell on CalifGym?
No. CalifGym does not accept orders, hold funds or connect user accounts to a trading platform.
Are these sports market prices a prediction from CalifGym?
No. They describe current activity in an external market. CalifGym does not endorse the market outcome or provide financial or betting advice.
