Insider trading in crypto: the Coinbase listing case and what the rules say

In stock markets, trading on a company’s secrets before they’re announced is a classic crime. Crypto has its own version: knowing which coins an exchange is about to list before the public does. In 2022 the SEC brought a case over exactly that, involving an employee of the US exchange Coinbase.

This guide explains what insider trading is, what happened in the Coinbase case and how it ended, how regulated exchanges are expected to protect listing information, and the UK’s coming ban. For how listings are decided, see how crypto exchanges decide which coins to list.

What insider trading is

Investor.gov, the SEC’s site for investors, describes illegal insider trading as buying or selling a security, in breach of a duty of trust and confidence, on the basis of material, nonpublic information. Violations can also include:

• tipping such information to someone else;
• trading by the person who was tipped;
• trading by people who misappropriate, or steal, confidential information, for example from an employer.

The SEC’s examples include employees who trade after learning confidential developments, and the friends and family members they tip.

The Coinbase listing case

On 21 July 2022, the SEC charged a former Coinbase product manager, Ishan Wahi, his brother Nikhil Wahi, and his friend Sameer Ramani. According to the SEC’s complaint:

• Ishan helped coordinate Coinbase’s public listing announcements, including which crypto assets would become available for trading;
• Coinbase treated that information as confidential and warned employees not to trade on it or tip others;
• from at least June 2021 to April 2022, he repeatedly tipped the timing and content of upcoming announcements to his brother and his friend;
• they bought at least 25 crypto assets ahead of the announcements, which usually pushed prices up, and typically sold them shortly afterwards for a profit;
• the scheme generated illicit profits of more than $1.1 million.

The SEC alleged that at least nine of those assets were securities, which is what brought the case under the securities laws. Its enforcement director said the agency wasn’t concerned with labels but with “the economic realities of an offering”. On the same day, the US Attorney’s Office for the Southern District of New York announced criminal charges against all three in a parallel case.

How it ended

The SEC’s case ended in March 2024. Its litigation release says the court entered final judgments against Ishan and Nikhil Wahi first. On 1 March 2024, it entered a default judgment against Ramani, who was ordered to pay:

The judgment also permanently bars him from violating the anti-fraud provisions of the securities laws.

Insider trading, front-running and manipulation

Several kinds of unfair trading get lumped together in crypto. They’re different things:

What sets insider trading apart is the source of the edge: information that someone was trusted to keep confidential, rather than information anyone could see.

Why the “security” question matters

The securities laws’ insider trading rules apply to securities. That’s why the SEC’s case depended on its view that some of the coins were securities. The classification of crypto has since moved on: in March 2026, the SEC set out categories of crypto assets and listed bitcoin and ether among its examples of digital commodities, which aren’t themselves securities. See is crypto a security? The Howey test.

That doesn’t mean trading on stolen confidential information is safe for other coins. In the Coinbase case, prosecutors brought their own criminal case alongside the SEC’s, and other laws can apply to misusing an employer’s confidential information.

How exchanges are expected to guard the secrets

Listing decisions are valuable information, so regulators expect exchanges to control them. New York’s 2023 listing guidance requires regulated exchanges to:

• assess and publicly disclose conflicts of interest in coin listing decisions;
• keep a record of coins held personally by board members and others who might influence a delisting decision;
• use that record to put information barriers around conflicted decision-makers, to avoid the risk of market manipulation or insider trading.

California’s crypto licensing law also requires exchanges to disclose material conflicts of interest linked to the coins they list. See California’s DFAL crypto license.

The UK: a ban from October 2027

The UK is building a specific regime. From 25 October 2027, the FCA’s Market Abuse Regime for Cryptoassets will prohibit insider dealing, unlawful disclosure of inside information and market manipulation in crypto, with extra monitoring duties for large platforms. See the UK’s new crypto rules for 2027.

What it means for you

• Treat “listing tips” with suspicion. Someone offering inside knowledge of an upcoming listing may be breaking the rules, or may simply be running a scam. See pump-and-dump schemes.
• If you work in crypto, follow your employer’s trading policy. The Coinbase case shows that tipping friends or family can be enough to get everyone charged.
• Don’t assume the market is level. Rules and information barriers are meant to reduce insider trading; they can’t guarantee it never happens.
• Report it. In the US, you can send tips about suspected securities violations to the SEC. See how to report crypto scams.
