What is Starting Price (SP) in Betting?
Starting price, commonly abbreviated as SP, refers to the official odds of a selection at the exact moment an event begins. In the context of UK betting, particularly horse racing and greyhound racing, the starting price is the price at which a bet is settled if no fixed odds were agreed upon at the time the wager was placed. Rather than locking in odds when you place your bet, starting price betting allows your odds to be determined at the "off" — the moment the race or event commences.
The starting price system is a fundamental component of traditional UK betting culture, particularly in on-course betting environments. It represents the final consensus of the betting market, reflecting all the money wagered, market movements, and betting sentiment right up to the moment the event starts. This makes starting price betting distinct from fixed odds betting, where the price you see is the price you get, regardless of subsequent market changes.
The Origin and History of Starting Price
The concept of starting price has deep roots in British betting tradition, dating back to the era of on-course bookmaking. Before the advent of digital betting platforms and real-time odds updates, bettors would place their wagers with on-course bookmakers at the racecourse itself. The starting price emerged as a natural solution to a practical problem: how to determine fair odds for bets placed before the race commenced.
In the early days of horse racing betting in Britain, bookmakers would continuously adjust their odds based on the volume of bets they received on each selection. As race time approached, the odds would stabilise, and the final price displayed on the bookmakers' boards at the moment the race started became the "starting price." This price represented the collective judgment of the market — the point at which supply and demand for bets on a particular horse reached equilibrium.
The starting price system became so important to the integrity of British betting that it eventually became formalised and regulated. The Starting Price Regulatory Commission (SPRC) was established to oversee the system and ensure fairness across the betting market. Today, starting price remains a cornerstone of UK horse racing betting, though its role has evolved with the rise of online betting exchanges and digital betting platforms.
How is Starting Price Determined?
Understanding how starting prices are determined requires knowledge of both the on-course betting market and the regulatory framework that governs it.
The On-Course Betting Market
Starting prices are primarily determined by the on-course fixed-odds betting market at racecourses across the UK. On-course bookmakers stand at the racecourse with their odds displayed on boards, adjusting prices in real-time based on the bets they receive. This creates a dynamic market where prices fluctuate constantly as bettors place their wagers.
Several factors influence how bookmakers adjust their odds:
- Betting Volume: When significant money is wagered on a particular selection, bookmakers will shorten the odds to reduce their liability.
- Backing vs Laying: If more money comes in to back a horse (bet on it to win), the odds shorten. If more money comes in to lay a horse (bet against it), the odds lengthen.
- Information and Market Sentiment: News about a horse's form, jockey changes, or track conditions can trigger rapid price adjustments.
- Competitor Prices: Bookmakers monitor what other on-course bookmakers are offering and adjust accordingly to remain competitive.
The Starting Price Regulatory Commission (SPRC)
The SPRC plays a crucial role in the starting price system. This independent body is responsible for determining the official starting price for each selection in races where betting is conducted. The SPRC collects data from multiple on-course bookmakers and uses a standardised methodology to calculate an official starting price that represents a fair consensus of the market.
The SPRC's role ensures integrity and prevents manipulation. By collecting prices from multiple bookmakers rather than relying on a single source, the system guards against bias or collusion. The official starting price is recorded and published, and all bets placed at starting price are settled at this official figure.
Factors That Influence Starting Price
| Factor | Impact | Example |
|---|---|---|
| Late Betting Movements | Significant impact | Heavy backing in final minutes shortens odds |
| Withdrawals/Scratches | Can lengthen remaining selections' odds | Horse withdrawn increases odds for others |
| Weather Changes | Can shorten or lengthen | Sudden rain might favour certain runners |
| Jockey/Trainer News | Can move odds substantially | Last-minute jockey change could shorten odds |
| Track Conditions | Affects suitability of runners | Firm ground favours certain horses |
| Market Liquidity | Lower liquidity = larger price swings | Small bet can move odds significantly |
| Betting Exchange Activity | Increasingly influences on-course prices | Large exchange bets can trigger bookmaker adjustments |
The starting price you ultimately receive represents the culmination of all these factors, combined with the SPRC's official calculation at the moment the race begins.
What's the Difference Between Starting Price and Fixed Odds?
This is one of the most important distinctions for bettors to understand, as it fundamentally affects how your bet is settled.
Fixed Odds Explained
Fixed odds betting means the price you agree to when you place your bet is the price you receive if your selection wins. Once you've placed your wager at, say, 5/1, that's locked in. If the odds subsequently shorten to 3/1 or lengthen to 8/1, it makes no difference — your returns are calculated at 5/1.
Example: You back a horse at 5/1 fixed odds with a £10 stake. The odds then shorten to 3/1 as more money comes in. If your horse wins, you receive £60 (£10 × 5/1) plus your £10 stake returned, regardless of the final starting price.
Starting Price Explained
Starting price betting defers the odds determination until the race begins. You place your bet without knowing the exact odds you'll receive. Instead, your bet is settled at whatever the official starting price is at the moment the race starts.
Example: You place a £10 starting price bet on a horse when the odds are 4/1. By the time the race starts, the starting price has moved to 6/1. Your bet is settled at 6/1, giving you £70 (£10 × 6/1) plus your stake if the horse wins.
The starting price could also move against you. If you placed your bet when the horse was 4/1, but the starting price is 2/1, you receive lower returns than you might have expected.
Side-by-Side Comparison
| Aspect | Fixed Odds | Starting Price |
|---|---|---|
| Price Lock | Locked when bet placed | Determined at race start |
| Certainty | Guaranteed odds | Odds unknown until off |
| Potential Upside | Limited to fixed price | Unlimited if odds lengthen |
| Downside Risk | Only if selection loses | Odds could shorten significantly |
| Availability | Widely available online | Limited online; mainly bookmakers |
| Timing Advantage | Can lock in good odds early | Rewards late market knowledge |
| Simplicity | Very straightforward | More complex |
| Market Sentiment | Reflects price at bet time | Reflects final market consensus |
How Do You Place a Starting Price Bet?
Placing a starting price bet depends on where and how you want to bet.
With Traditional Bookmakers
Traditional bookmakers — whether on-course or off-course — will accept starting price bets, though the process differs from fixed odds betting.
On-Course: At a racecourse, you can approach a bookmaker and explicitly request an SP bet. You might say, "£10 starting price on [horse name]." The bookmaker will note your bet, and when the race starts, your bet is settled at the official starting price.
Off-Course: Some traditional bookmakers (including some high street shops, if they still exist) will accept SP bets via telephone or in person. You specify that you want the starting price, and your bet is recorded accordingly.
Online: Many online bookmakers offer starting price betting, though it's less common than fixed odds. You'll typically find an "SP" option on the betting slip or market page. Some bookmakers restrict SP betting to certain events or markets.
With Betting Exchanges: Betfair Starting Price (BSP)
Betting exchanges like Betfair have their own version of starting price called Betfair Starting Price (BSP) or Exchange Starting Price. The BSP is calculated differently from traditional starting price.
On Betfair, you can place a bet to be matched at the BSP. The BSP is determined by the matched odds on the exchange in the final seconds before the event starts. Specifically, Betfair uses the prices available at the moment the market turns in-play (typically the moment the race starts) to calculate the BSP.
Key Difference: BSP is determined by exchange prices, not on-course bookmaker prices. This can result in different odds than the traditional starting price, though the two often move in tandem.
Each Way Bets at Starting Price
An each way bet at starting price works similarly to fixed odds each way betting, except both the win and place parts are settled at starting price.
An each way bet consists of two separate bets:
- Win Bet: Your selection wins the race
- Place Bet: Your selection finishes in the places (typically the first 2–4 runners, depending on field size)
When you request an each way starting price bet, you receive two starting prices — one for the win market and one for the place market. The place odds are typically a fraction of the win odds (e.g., 1/4 or 1/5 of the win odds).
Example: You place a £10 each way starting price bet. The starting price is 6/1 for the win and 1/4 of 6/1 (i.e., 1/1.50) for the place. If your horse wins, you receive returns on both the win and place bets. If it finishes placed but not first, you only receive returns on the place bet.
Advantages and Disadvantages of Starting Price Betting
Advantages
Potential for Better Odds: If you place your bet when the market is offering longer odds than the final starting price, you win. This rewards bettors who have good market timing or access to information before the general betting public.
Fairness in On-Course Betting: The SPRC system ensures that the starting price represents a fair consensus of the market, not the whim of a single bookmaker. This is why many traditional bettors prefer starting price.
Flexibility in Timing: You don't need to commit to a price immediately. You can place your bet with the knowledge that if the market moves in your favour, you benefit.
Access to Market Movement: Starting price betting allows you to participate in the dynamics of the betting market in a way fixed odds doesn't.
Disadvantages
Uncertainty Until Race Start: You don't know your odds when you place the bet. This can be psychologically uncomfortable for some bettors.
Odds Could Shorten Significantly: If the market moves against your selection, your odds could be substantially shorter than when you placed the bet. This can result in lower returns than expected.
Limited Availability: Starting price betting is not available for all markets or all bookmakers, particularly online. It's most readily available for win markets in horse racing.
Complexity: Starting price betting is more complex than fixed odds, which can be a barrier for novice bettors.
Regulatory Limitations: Not all bookmakers accept starting price bets, and some restrict them to certain events or markets.
Common Misconceptions About Starting Price
Myth 1: You Can Always Request Starting Price
Reality: Starting price availability is limited. While you can request it from some traditional bookmakers, many online bookmakers don't offer it. Off-course bookmakers may also refuse SP bets on certain events or markets. On-course at a racecourse, you'll have better luck finding bookmakers willing to accept SP bets.
Myth 2: Starting Price is Always Better Than Fixed Odds
Reality: This is false. Starting price is only better if the market moves in your favour (odds lengthen). If the market moves against you, starting price can be significantly worse than the fixed odds you could have taken earlier. The advantage depends entirely on market movement and your timing.
Myth 3: Starting Price is Only for Horse Racing
Reality: While starting price is most common in horse racing, it's also used in greyhound racing and, increasingly, in other sports where on-course betting is prevalent. However, it's rare in football, tennis, and other sports where fixed odds and betting exchanges dominate.
Myth 4: The Starting Price is Always the Same Across All Bookmakers
Reality: The official starting price determined by the SPRC is standardised, but individual bookmakers may have offered slightly different odds before the race. However, when the race starts, the official SPRC starting price is what matters for bets placed at starting price.
Myth 5: You Can Place Starting Price Bets After the Race Starts
Reality: Starting price bets must be placed before the race begins. Once the race is underway, you cannot place a starting price bet. The odds are determined at the moment the race starts, not after.
Starting Price in Modern Betting
The Evolution of Starting Price in the Digital Age
The rise of online betting and betting exchanges has transformed the starting price landscape. Historically, starting price was the primary way off-course bettors could access fair odds, as they didn't have direct access to on-course bookmakers. Today, with real-time odds available online, the advantage of starting price is less clear.
However, starting price remains relevant for several reasons:
Regulatory Tradition: Starting price is embedded in UK betting regulation and tradition. Many bettors still prefer it for its perceived fairness.
Market Dynamics: Some bettors use starting price strategically, placing bets early when they believe odds will lengthen before the race starts.
Exchange Integration: Betting exchanges now calculate their own starting prices, allowing exchange bettors to participate in the starting price system.
Starting Price vs. Betting Exchange Odds
Betting exchanges have introduced a different model. Rather than relying on bookmaker odds or the SPRC's calculation, exchanges determine odds through supply and demand on their own platforms. This has created a parallel market to traditional starting price.
Interestingly, exchange prices and traditional starting prices often converge by race time, as both reflect the same underlying market. However, they can diverge during the day as different types of bettors use each platform.
The Future of Starting Price
The future of starting price is uncertain. As younger bettors increasingly prefer online betting and betting exchanges, the traditional starting price system may become less central to UK betting. However, regulatory support and the perceived fairness of the system suggest it will remain relevant for the foreseeable future.
Technological advancements may also change how starting prices are calculated and distributed. Real-time data and artificial intelligence could enable more sophisticated methods of determining fair starting prices.
Frequently Asked Questions About Starting Price
What does SP stand for?
SP stands for "Starting Price." It refers to the official odds of a selection at the moment an event (typically a horse race) begins. The term is sometimes also used to mean "Industry Starting Price" or "ISP" in certain contexts, though these are technically different.
How is starting price different from fixed odds?
With fixed odds, the price you see when you place your bet is the price you receive if your selection wins. With starting price, you don't know your odds until the race starts. Your bet is settled at whatever the official starting price is at the moment the race begins. This means starting price odds can be better or worse than fixed odds, depending on how the market moves.
Can I request starting price online?
Starting price is less commonly available online than fixed odds. Some online bookmakers offer it, but it's typically restricted to certain markets and events. Betting exchanges like Betfair offer their own version (BSP). For the widest starting price options, traditional bookmakers (by phone or in person) are your best bet.
What is BSP (Betfair Starting Price)?
BSP is Betfair's version of starting price. Rather than being determined by on-course bookmakers and the SPRC, BSP is calculated based on the odds available on the Betfair exchange in the final seconds before an event starts. BSP is often similar to traditional starting price but can differ depending on exchange activity.
Is starting price only for horse racing?
While starting price is most common in horse racing, it's also used in greyhound racing. It's rare in other sports like football or tennis, where fixed odds and betting exchanges are the dominant betting methods.
Can starting price be worse than the odds I saw earlier?
Yes, absolutely. If you place a starting price bet when odds are 4/1, but the starting price is 2/1, you receive lower odds than you anticipated. The starting price reflects the final market consensus, which could move against your selection.
How long do I have to place a starting price bet?
You must place a starting price bet before the race or event begins. Once the event is underway, you cannot place a starting price bet. The odds are determined at the moment of the "off" — the start of the race.
What happens if a horse is scratched after I place an SP bet?
If your selection is scratched (withdrawn) after you've placed your starting price bet, your bet is void, and your stake is returned. The scratch typically occurs before the race starts, so your bet is cancelled before the starting price is even determined.
Why would I choose starting price over fixed odds?
You might choose starting price if you believe the market will move in your favour — that odds will lengthen before the race starts. You might also choose it if you prefer the perceived fairness of the starting price system, or if you're betting late and want to capture any last-minute market movements.
Where can I see the official starting price?
The official starting price determined by the SPRC is published by major betting operators and racing websites. Most online bookmakers and betting exchanges display the starting price for completed races. You can also find historical starting prices on racing databases and statistics websites.
