18+ Betting money on cricket carries a direct risk of financial loss, and it can become an addiction. Real-money online gaming is banned across India under the PROG Act 2025, which came into force on 1 May 2026.

If betting is already costing you money you need, or sleep, or people close to you, the free Tele-MANAS helpline is **14416**, and it runs in 20 languages. Our [page on help for gambling harm](/guides/help-for-gambling-harm-india) lists what else exists.

Follow a cricket price from model to screen: base chance, added margin, money flow and line moves, plus stake limits and closed accounts.

Cricket prices are manufactured in four steps. A model estimates a chance for each outcome. A fee is added, so the quoted chances pass 100%. The prices go live. Then they move as money arrives and as the match changes. Winners are paid below the seller's own fair value, and that locks in the profit.

This page walks through each step with a worked mark-up. It also shows regulator data on stake limits and closed accounts. Then it lists what is not in the chain, such as inside knowledge and signals you could decode.

## The chain from model to screen has four links

A cricket price is manufactured. It is not discovered, and it is not leaked. Four steps turn a match into a number.

- A base chance for each outcome is estimated.
- A fee is added on top of those chances.
- The chances are turned back into prices and published.
- The prices are then moved as money arrives and as the match changes.

Every step is done for the seller's benefit. That is not a scandal. It is the business model, and knowing it removes most myths about odds.

One legal fact belongs here. Real-money online games are banned in India by the PROG Act 2025. It came into force on 1 May 2026. The ban reaches offshore operators too ([Nishith Desai](https://nishithdesai.com/research-and-articles/hotline/gaming-law-wrap/setting-the-rules-of-the-game-indias-online-gaming-law-comes-into-force-15586)). This page describes a process. It does not point you at anyone running it.

## Step one: estimating the base chance

The starting point is a probability for each result. Two sides of a T20 might start at 55% and 45%.

Where does that come from? Match records, player form, venue history and conditions. A bookmaker works a bit like an actuary. It balances outcomes so the money adds up whichever way the event goes ([Wikipedia on bookmakers](https://en.wikipedia.org/wiki/Bookmaker)).

The estimate is never exact. Fixed-odds pricing openly admits this. A seller cannot know the true chance of a contest decided by human effort. It also cannot know which prices will pull money ([Wikipedia on fixed-odds betting](https://en.wikipedia.org/wiki/Fixed-odds_betting)).

Cricket facts feed the model. A T20 innings is 20 overs, which is 120 legal deliveries ([Wikipedia on Twenty20](https://en.wikipedia.org/wiki/Twenty20)). An ODI innings is 50 overs ([Wikipedia on ODIs](https://en.wikipedia.org/wiki/One_Day_International)). Ten wickets end an innings. Five ways of being out are common, and a few more are rare ([Wikipedia on dismissals](https://en.wikipedia.org/wiki/Dismissal_(cricket))). Our [page on pitch conditions](/guides/how-pitch-conditions-work) covers the biggest single input.

## Step two: adding the fee before you ever see the price

The model gives chances that add to 100%. The published prices do not. The seller marks the book up. The quoted chances then total more than 100%, and that excess is the overround ([Wikipedia](https://en.wikipedia.org/wiki/Fixed-odds_betting)).

The payout side is shaded down. Winners get odds below the seller's own view of fair value. That is what secures the profit ([Wikipedia on the mathematics of bookmaking](https://en.wikipedia.org/wiki/Mathematics_of_bookmaking)).

**Inputs.** Model says Team A 55%, Team B 45%. Target book 105%.

**Formula.** Fair price = 1 ÷ chance. Marked-up chance = chance × 1.05. Published price = 1 ÷ marked-up chance.

**Result.** Fair prices: 1 ÷ 0.55 = 1.82 and 1 ÷ 0.45 = 2.22. Marked up: 0.55 × 1.05 = 57.75% and 0.45 × 1.05 = 47.25%. Published: 1 ÷ 0.5775 = 1.73 and 1 ÷ 0.4725 = 2.12. Book check: 57.75% + 47.25% = 105.00%.

**Assumptions.** The 55/45 split and the 105% target are ours, picked to show the method. Real sellers split the mark-up unevenly and often load more of it onto the outsider. Rounding on a screen shaves a little more off the price.

Notice what happened. The fair price of 1.82 reached you as 1.73. Nothing dishonest was done. The fee simply arrived before you did. The rupee cost of that step is set out on our [overround page](/guides/what-is-overround).

## Step three: money moves the price

Once prices are live, the seller watches the flow. The aim is a balanced book. That means the amounts staked on each side match the odds on offer ([Wikipedia](https://en.wikipedia.org/wiki/Bookmaker)).

When one side draws too much, the price on that side is cut and the other side is lengthened. Large exposure can also be laid off with another firm ([Wikipedia](https://en.wikipedia.org/wiki/Bookmaker)).

So a price drop tells you money arrived. It does not tell you the outcome became more likely in reality. Those two things get confused constantly.

Modern online pricing runs this loop live. Real-time feeds, risk algorithms and constant adjustment as bets land ([Wikipedia](https://en.wikipedia.org/wiki/Mathematics_of_bookmaking)). Reporting on India's illegal networks describes ball-by-ball pricing in IPL matches. Odds there change on each ball after boundaries, sixes and wickets ([NDTV](https://www.ndtv.com/india-news/inside-the-shadow-economy-riding-ipl-online-betting-networks-11560908)).

**Inputs.** A side opens at 2.00. Money floods in. The price is cut to 1.85.

**Formula.** Implied chance = 1 ÷ price. Change = new chance − old chance.

**Result.** 1 ÷ 2.00 = 50.00%. 1 ÷ 1.85 = 54.05%. The move added 4.05 points of implied chance.

**Assumptions.** The prices are ours, chosen to show the size of a common move. Part of that 4.05 points is a real change in view. Part is only the fee being widened. From outside, you cannot tell which part is which.

You are betting into a price that is being corrected while you tap.

Nothing on the screen labels which part of a move is opinion and which part is padding. Our [explainer on reading odds](/guides/how-cricket-odds-work) shows how to check what a moving price implies.

## Step four: limits, stake factors and closed accounts

Pricing is only half of risk control. The other half is deciding who may bet, and how much.

British regulator data makes the scale clear. It covered 14,923,840 active accounts in 2024. Of those, 643,779 sat under some restriction. That is 4.31% ([Gambling Commission](https://www.gamblingcommission.gov.uk/blog/post/commercial-restrictions-by-betting-operators)).

The commonest measure was a stake factor. It caps your largest stake at a share of what a normal customer may bet. It covered 2.68% of active accounts ([Gambling Commission](https://www.gamblingcommission.gov.uk/blog/post/commercial-restrictions-by-betting-operators)).

Closures for commercial reasons hit 2.23% of active accounts ([Gambling Commission](https://www.gamblingcommission.gov.uk/blog/post/commercial-restrictions-by-betting-operators)). The regulator's own position is blunt. Operators may act in their commercial interest. There is no universal service obligation in gambling. Being a winning bettor is not a protected trait in law ([Gambling Commission](https://www.gamblingcommission.gov.uk/blog/post/commercial-restrictions-by-betting-operators)).

**Table 1. Commercial restrictions reported by large British online betting operators for 2024**

| Measure | Figure reported | What it means for a customer |
|---|---|---|
| Active customer accounts | 14,923,840 | The base the percentages are taken from ([Gambling Commission](https://www.gamblingcommission.gov.uk/blog/post/commercial-restrictions-by-betting-operators)) |
| Accounts with any restriction | 643,779, or 4.31% | About 1 account in 23 was limited in some way ([Gambling Commission](https://www.gamblingcommission.gov.uk/blog/post/commercial-restrictions-by-betting-operators)) |
| Stake factor applied | 2.68% of active accounts | Your maximum stake is cut to a share of the normal limit ([Gambling Commission](https://www.gamblingcommission.gov.uk/blog/post/commercial-restrictions-by-betting-operators)) |
| Closed for commercial reasons | 2.23% of active accounts | The account is shut, not for rule breaking ([Gambling Commission](https://www.gamblingcommission.gov.uk/blog/post/commercial-restrictions-by-betting-operators)) |

That data is British. It comes from a licensed market where a regulator collects figures. No such count exists for apps serving India . India has no licence regime for them to report into. We will not guess a number for it.

The practical meaning is simple. On an exchange, a limited bettor can still get matched. Someone just has to take the other side ([Wikipedia on betting exchanges](https://en.wikipedia.org/wiki/Betting_exchange)). With an agent account there is no regulator to complain to. Our [page on cricket IDs](/guides/cricket-id-and-agent-accounts) explains why.

## What is not in this chain at all

Now the myths. None of the following is part of how prices are made.

- No inside knowledge of the result. The seller is estimating, and it says so through the pricing model it uses ([Wikipedia](https://en.wikipedia.org/wiki/Fixed-odds_betting)).
- No secret signal in a price move. Movement mostly means money, as the balancing rule shows ([Wikipedia](https://en.wikipedia.org/wiki/Bookmaker)).
- No arrangement you could guess. If a market could be decoded, the fee would not need to exist.
- No pattern in past prices that predicts the next one. That belief has a name. It is the gambler's fallacy: the idea that an outcome is due because it has been missing ([Wikipedia on the gambler's fallacy](https://en.wikipedia.org/wiki/Gambler%27s_fallacy)).
- No tipster with the seller's model. The model is the asset. It does not leave the building.

Corruption in cricket is a real and separate matter. Spot-fixing means fixing one event inside a match that a betting market exists on. The timing of a no-ball is the classic case. The final result need not change at all ([Wikipedia on spot-fixing](https://en.wikipedia.org/wiki/Spot-fixing)).

The ICC has a code for this. It covers match fixing and spot fixing, betting on cricket, misuse of inside information and failing to report approaches. A global version took effect on 1 June 2024 ([ICC](https://www.icc-cricket.com/about/integrity/anti-corruption/the-code-pmoa)).

We name no player and no match. We make no claim about any current game. The point for a reader is narrower. Because such events exist, small in-match markets carry extra padding. That is one reason the fee is highest where the excitement is ([see our fancy bets page](/guides/fancy-bets-explained)).

## What the process means for a reader in India

Five things follow from all of the above.

- The fee is set before you arrive, so no timing trick removes it.
- Winning consistently attracts limits, because managing liability is normal practice ([Gambling Commission](https://www.gamblingcommission.gov.uk/blog/post/commercial-restrictions-by-betting-operators)).
- A moving price is information about money, not about the match.
- Tax lands on winnings anyway. The rate is a flat 30% under Section 115BBJ ([Income Tax Department](https://www.incometaxindia.gov.in/w/section-115bbj)). It is withheld under Section 194BA, with no minimum limit ([Income Tax Department](https://www.incometaxindia.gov.in/w/winnings-from-online-games)).
- The activity itself is banned nationwide under the central Act, as our [PROG Act explainer](/legal/prog-act-2025-explained) sets out.

## Questions people ask

### Do bookmakers know the result in advance?

No. Fixed-odds pricing is built on estimates. The seller cannot know the true chance of a contest decided by human effort ([Wikipedia](https://en.wikipedia.org/wiki/Fixed-odds_betting)). Prices are then corrected as money arrives.

### Why did my account get a smaller maximum stake?

That is a stake factor. British regulator data shows it applied to 2.68% of active accounts in 2024. The regulator says operators may manage their own liabilities ([Gambling Commission](https://www.gamblingcommission.gov.uk/blog/post/commercial-restrictions-by-betting-operators)).

### Does a sudden price drop mean something is fixed?

Usually it means money landed on that side and the book is being rebalanced ([Wikipedia](https://en.wikipedia.org/wiki/Bookmaker)). Corruption in cricket exists as a separate problem, and spot-fixing is defined and policed under the ICC code ([ICC](https://www.icc-cricket.com/about/integrity/anti-corruption/the-code-pmoa)). We make no claim about any specific match.

### Are Indian apps limiting accounts the same way?

We have no published figures for apps serving India . There is no Indian licensing regime collecting that data, and offering these games is banned outright ([Nishith Desai](https://nishithdesai.com/research-and-articles/hotline/gaming-law-wrap/setting-the-rules-of-the-game-indias-online-gaming-law-comes-into-force-15586)).

### Who sets prices on an exchange?

Users do, by backing and laying against each other. The platform is not a party to the bet and earns a commission on net winnings ([Wikipedia](https://en.wikipedia.org/wiki/Betting_exchange)).
