Crypto and Insider Trading

The crypto market is known for rapid price movements and new developments. But just as in traditional financial markets, a less transparent phenomenon also plays a role here: insider trading. In 2026, the regulation around this topic has fundamentally changed due to the full implementation of the European MiCA regulation, whereby practices that previously fell in a grey area are now explicitly punishable.

Insider trading, or trading on inside information, can have a major influence on the prices of cryptocurrencies. Through access to information that is not yet public, certain parties can trade earlier than the rest of the market. In this article you read what insider trading is, how it works in crypto and how you can recognise it as an investor.

In short

• Insider trading is trading with non-public information.

• It also occurs in the crypto market and affects the fairness of the price.

• It often happens around listings on exchanges and important project announcements.

• It can lead to unfair price advantages at the expense of regular investors.

• Since 2026, the regulation (MiCA) in the EU is strict and the detection techniques have improved.

What is insider trading?

Insider trading means that someone trades based on information that is not yet public. This information can influence the price of an asset as soon as it becomes publicly known.

Insider trading meaning: trading on inside information

With insider trading, someone has access to important information before it is made public. For example:

• An upcoming listing on a large exchange.

• A new collaboration or partnership with a large technology company.

• A large capital injection or investment in a project.

By using this information earlier, an insider can make a profit or prevent a loss before the rest of the market can react.

Legal vs. illegal insider trading

Not all insider trading is automatically illegal. In traditional markets, insider trading can be legal if it happens transparently and is reported to regulators according to strict rules. Illegal insider trading takes place when someone abuses confidential information without reporting it or while having a duty of confidentiality. In the crypto market this distinction was vague for a long time, but in 2026 this has been fully brought in line with the stock market by MiCA in Europe: trading on inside information in crypto is now prohibited and punishable.

How does insider trading work in crypto?

Insider trading in crypto often follows a similar pattern that abuses the timeline on which information becomes public.

Step 1: Access to non-public information

The first step is access to information that is not yet public. This can be, for example, via employees of exchanges who see the planning of new listings, project developers who work on a major update, or partners and investors who are involved in a merger.

Step 2: Buying in before the announcement

With this information, someone can buy crypto while the price is still low, because the market is not yet aware of the good news. Multiple new wallets are often used for this to hide the activity from on-chain analysts.

Step 3: Selling after the price increase

As soon as the announcement is official, the price often rises quickly due to the sudden demand. The insider can then sell their tokens to the new buyers and exit with a profit.

Forms of insider trading in crypto

There are various ways in which insider trading occurs in the digital asset market.

Insider trading with exchange listings

When a cryptocurrency is added to a large exchange, the liquidity and exposure increase, which often leads to a price increase. People with inside information can respond to this by buying the coin in advance on a small decentralised exchange (DEX).

Front-running

Front-running means that someone places an order just before a large transaction is executed of which one knows that it is going to influence the price. In DeFi this often happens via bots that scan the mempool and 'jump ahead' of transactions with a higher gas fee.

Trading before project announcements

Projects regularly announce updates, mainnet launches or major collaborations. Insiders often use these technical or commercial milestones to take positions before the marketing machine goes into full swing.

Pump and dump with inside information

In some cases, insider trading is combined with pump and dump schemes. Here, trading is not only done based on real news, but the price is also artificially inflated via social media to maximise the profit of the insiders.

Well-known examples of insider trading in crypto

Over the years, various cases have come to light that underlined the need for regulation.

The Coinbase case

A well-known example is the case in which a former product manager of Coinbase shared information about tokens that were scheduled to be listed. This led to the first major prosecution for insider trading in the crypto sector.

Solidus Labs research: 56% of listings suspicious

Research by Solidus Labs showed that in a certain period, more than half of the listings on central exchanges were preceded by suspicious trading activity on decentralised exchanges. This suggests a widespread use of inside information in the industry.

Binance and the Gnosis wallet incident

Incidents have also been signalled at other large platforms where wallets bought up enormous quantities of tokens just before Binance announced a listing. These kinds of events have led to much stricter internal surveillance at exchanges.

Insider trading on prediction markets: the Polymarket cases

Insider trading does not only occur with the buying of coins, but also on platforms where bets are placed on the future.

What is Polymarket?

Polymarket is a decentralised platform where users can speculate on the outcomes of events, such as elections or sports matches.

The soldier who earned $400,000 with secret military info

There are known cases where military personnel or government officials with inside information about geopolitical or military events made large profits on prediction markets before the news reached the media.

Suspicious trades around Trump announcements and Iran

In 2025 and 2026, multiple incidents were reported where enormous bets were placed on specific political statements or military actions in the Middle East, mere minutes before they were officially confirmed.

Kalshi: politicians betting on their own elections

The rise of regulated markets such as Kalshi in the US caused discussion about politicians who bet on their own election result or on legislation they vote on themselves. This has led to new ethical guidelines for office holders.

What does this mean for the future of prediction markets?

The vulnerability to insider trading forces these platforms in 2026 to much more active supervision and better cooperation with authorities to safeguard market integrity.

Is insider trading in crypto illegal?

In 2026, the legal status of insider trading in crypto is much clearer than a few years ago.

Regulation in the Netherlands and the EU

Within the EU, the MiCA legislation is fully in force as of 2026. MiCA explicitly prohibits market abuse and trading on inside information for all providers of crypto services. The AFM keeps strict supervision on this in the Netherlands.

Regulation in the United States

In the US, the SEC prosecutes insider trading in crypto as a form of securities fraud. Several courts have confirmed that the laws that apply to stocks can also apply to digital assets.

The grey area in crypto

Although the grey area is getting smaller, it still exists for very small, new tokens that are not traded on regulated exchanges. Here, enforcement is more complex, but with the arrival of international standards, the loopholes in the law are getting smaller and smaller.

How is insider trading detected?

The open nature of the blockchain makes it easier than ever in 2026 to detect fraud.

On-chain analysis and blockchain forensics

Because all transactions are public, specialised companies can recognise patterns that point to inside information, such as a new wallet that becomes active for the first time just before a large price increase.

Wallet clustering and transaction traces

By analysing and 'clustering' wallets, researchers can make connections between anonymous wallets and accounts on exchanges where the identity of the user (KYC) is known.

Surveillance by exchanges

Regulated exchanges such as Coinmerce continuously monitor transactions with software that detects deviant trading behaviour, comparable to the systems used on traditional exchanges.

How do you recognise insider trading as an investor?

As an investor you can be alert to a number of signals:

• A sudden, sharp price increase without any news being found at that moment on official channels.

• An unusually high trading volume in the hours before an important press release comes out.

• Large wallet movements on the blockchain where 'whales' take positions in a coin that previously knew hardly any activity.

How do you protect yourself as an investor?

You cannot prevent insider trading, but you can protect yourself by:

• Always doing your own research and not blindly reacting to price increases.

• Not trading purely based on hype or rumours on social media.

• Being careful with coins that show sudden, unexplained price movements.

• Spreading your investments across different assets to limit the impact of a manipulated coin.
