Prediction Market

A prediction or betting market is a platform where individuals predict and bet on future events. Based on the success of the prediction, the participant makes profits or losses. Hence, the primary purpose of this market is to provide a more accurate and efficient way to predict the likelihood of future events.

The market prices of these events indicate the joint probability of other individuals in the prediction market. Hence, this can act as a guide to the participant in understanding the market's prediction. The individual further uses additional information and judgment in making the prediction. Predictions are usually related to politics, financial markets, global events, and other investments.

• A prediction market is an open marketplace where individuals can predict real-world political, social, and sports-related events. 
• Since betting using legal currencies is illegal in most countries, betting platforms use virtual tokens to facilitate a betting space for participants.
• Due to this, the crypto prediction market is gaining popularity, especially with Bitcoins and Ethereum.
• These markets have been used for various purposes, including forecasting election outcomes, predicting financial market movements, and making investment decisions. Companies use them to make informed- investment decisions.

The prediction market refers to an open space where individuals can place their bets related to real-world events over which they have no control. Instead, they use news, the internet, social media, and other sources to make the best predictions. Hence, the market prediction keeps changing with the individual forecasts of the participants. For instance, if Individual A says the probability of an event is 0% and another Individual B predicts the probability as 100%, the market prediction is 50% (average).

So, how exactly does a prediction market work? This market allows individuals to buy and sell shares in the outcome of a particular event or future scenario. Therefore, each share's price indicates the event's perceived occurrence. Besides, higher prices indicate greater confidence in the event occurring. Furthermore, if the event does not happen, the shares become worthless, and the individual loses their investment.

Furthermore, the price of shares in this market is determined by the supply and demand of the market. Additionally, these markets are built on a decentralized network, such as blockchain, known as decentralized prediction markets. Decentralized market predictions use smart contracts to facilitate the buying and selling of shares in the outcome of an event. Hence, in a crypto prediction market, participants can use cryptocurrencies such as Bitcoin, Ethereum, or other tokens to buy and sell shares in the outcome of an event.

With this, it is essential to mention the surprising accuracy of predictions made by these markets. Often, these markets' social and political predictions have far bested the forecasts by experts. Besides, this is due to the heavy research conducted by the participants who bet for money. It also depicts the wisdom of the crowd, replicating the population's behavior.

Let's look at the classification of prediction markets. 

#1 – Continuous Double Auction (CDA) Markets

The CDA market works like a stock market, matching buyers and sellers according to the bets they place. The operator must maintain the ledger and reach people who place opposite bets. Therefore, if a buyer wants to purchase a share of $1, they will place a bid. Hence, this has to match with a seller who places an ask for $1. The problem with this type is that considering the market size, there might need to be more sellers or buyers for each bid or ask placed.

#2 – Automated Market Makers And Market Money Rules System

Due to the disadvantage of the CDA markets, automated market makers are often used to automatically place an opposing bet for every bet a trader places. Thus, it sets a bid for an ask and an ask for an offer. Therefore, the operator decides the price using the market scoring rules system.

#3 – Play money market

Since gambling with real money (legal tender) is illegalized by many governments, some prediction market websites and apps allow individuals to participate with virtual money or tokens. Later, based on the individual's success in making accurate predictions, they are awarded financial incentives or rewards by the operator.

#4 – Blockchain-Based Markets

The popularity of blockchain and its various other applications have paved the way for its adoption in betting markets. Besides, this allows individuals to stay anonymous while making real-time bets and predictions. Crypto prediction markets and assassination markets are some examples.

#5 – Crowdsourcing Markets

Crowdsourcing is where people share their opinions and judgments online via websites, apps, social media, etc. Crowd voting is a sub-type where people specifically vote as per their choices, predictions, etc. Therefore, this is used to select program winners and understand people's behavior.

Here are a few examples of prediction markets.

Example #1

Let's say there is a market prediction for the outcome of a presidential election in the U.S. Where the market operates on a binary outcome, meaning that the only two possible outcomes are candidate A winning or candidate B winning.

Therefore, this market opens with an initial price for each outcome. For example, the initial cost might be $0.60 for a share of Candidate A winning and $0.40 for a share of Candidate B winning. Hence, this implies that the market sees Candidate A as more likely to succeed.

Additionally, trades who believe that Candidate A will win can buy shares in that outcome, while traders who believe Candidate B will win can purchase shares in that outcome. Hence, as the election approaches and new information becomes available, the prices of the shares fluctuate in response to the changes in the market's assessment of the candidate's chances of winning. 

Therefore, on the day of the election, the market settles on the actual outcome, with the shares in the winning candidate paying out at $1.00 per share and the shares in the losing candidate becoming worthless. Thus, traders who accurately predicted the outcome would receive a payout proportional to the number of shares they held in the winning outcome.

Example #2

In recent years, the trend or fashion of "prediction markets" has evolved from an intellectual toy into a cottage industry. Thus, influenced by how the stock market seemingly gathers supply and demand for a company's shares, determining a price based on the weighted average of several million traders' opinions about the enterprise value, these technologically advanced platforms enable individuals to transact agreements that pay off if a specific outcome occurs.

Therefore, the visible growth of prediction markets in politics has garnered much attention. They have produced unexpectedly precise projections in close elections, surpassing traditional polling methods.

Hence, these markets are marketed to improve decision-making in various applications, including product development and inventory control, estimating the spread of epidemics, and crafting foreign policy.
