The same match event is sold at different prices depending on how quickly it is delivered. Latency, rather than content, is the main variable in what a data feed costs.
Speed has value only in comparison
A feed arriving in one second is worth far more than one arriving in five, but only because others are receiving the slower version.
Buyers pricing live markets need to react before the information is widely known, so their entire use case depends on holding a temporal advantage.
Suppliers therefore sell speed as a graded product, with the fastest tier restricted and expensive and slower tiers available broadly at low cost.
Tiers are created by deliberate delay
The supplier collects once and then holds the message for different intervals before releasing it to different classes of customer.
This costs nothing to implement and preserves the premium tier's advantage, which would otherwise evaporate the moment the data was distributed widely.
The practice is disclosed in contracts, and buyers know precisely what offset they are receiving relative to the fastest available feed.
Free consumer feeds sit at the slow end
Applications showing scores to the public generally use a delayed tier, since a viewer does not notice a few seconds and the cost difference is substantial.
That is why a score application can lag a stadium announcement or a social media post from someone present at the match.
Where an application does offer near-live updates, it is usually because the operator has another business, such as betting, that justifies the premium feed.
Infrastructure determines the achievable floor
Beyond collection speed, delivery depends on network routes, server placement and protocol choice, and suppliers colocate infrastructure near major customers to shave milliseconds.
Push delivery over a persistent connection beats polling, since a client asking repeatedly for updates learns of an event only at its next request.
These engineering decisions are marketed as product features, which is unusual outside financial data and reflects how similar the two markets have become.
Accuracy competes with speed
Reporting faster means reporting before verification, and a supplier that publishes an event later reversed damages the reliability it also sells.
Feeds therefore carry status flags marking provisional entries and subsequent corrections, so a buyer can decide whether to act on unconfirmed data.
Handling those corrections is the buyer's problem, which is why sophisticated customers build systems that can unwind a decision made on information later withdrawn.
