What is pump.fun Mayhem mode? Mayhem launches explained

Mayhem mode is a pump.fun launch setting: a bot gets 1 billion extra tokens and trades the coin at random for its first 24 hours, then burns what is left.

The candles look like a crowd is fighting over it. Some of that crowd is one bot with a free billion.

What Mayhem mode is

pump.fun calls it an experimental feature to bring volume and price swings to coins in their first hours, when most of them die quietly.

A creator picks it when the coin is made. It cannot be switched on later, and the bot never trades a coin that did not opt in.

What pump.fun's own pages say happens, as of 5 November 2026:

• Double supply. A normal pump.fun coin has 1 billion tokens. A Mayhem coin has 2 billion. The usual billion goes into the bonding curve, the same as any launch. The other billion goes to pump's trading bot.
• Same start. The starting market cap and the starting liquidity are the same as an ordinary coin.
• The bot trades in the first 24 hours. It buys and sells at random intervals and random sizes. pump.fun's mode page from November 2025 describes buys and sells with equal odds, a random walk. Its disclaimer, updated April 2026, says the bot may favour buying or selling, decided at pump's discretion, and that no one should trade on a guess of what it will do.
• Not every Mayhem coin gets traded. The bot runs on a limited number of coins at a time and picks among them at random.
• It stops, then burns. The mode ends after a set time or a set number of trades. Whatever the bot still holds is burned.
• Its trades pay no fees. The bot's own trades pay no pump.fun fees, including creator fees. Yours do.
• The tag stays. A Mayhem coin keeps its Mayhem tag after the mode ends.

How a Mayhem launch works on Solana

On an ordinary pump.fun curve, every token anyone sells was bought from the curve first. That gives the curve a floor: it cannot fall below where it opened.

Mayhem breaks that. The bot holds a billion tokens it never bought from the curve.

If it ends up a net seller, it sells those tokens into the curve, and the curve pays out SOL that real buyers put in. pump.fun's own page says that if the bot sells more than it buys and every holder then tries to sell, some holders may not be able to sell into the curve at all.

Once a coin graduates to PumpSwap, pump says traders can always sell for SOL, but by then the price can be very low.

Why Mayhem mode matters to a trader

• Volume is not demand. On a Mayhem coin, part of the buying and selling is the bot. Busy charts and high transaction counts prove less than they seem to.
• The floor is gone. The usual "a curve can't fall below its open" does not hold. See what is a bonding curve.
• Supply is double. Same price, twice the market cap. A Mayhem coin's numbers don't compare one to one with an ordinary launch until you account for that.
• Concentration reads differently. The bot's billion is half the supply, sitting in one place.
• You are trading against a bot that pays no fees. You pay the pool fee each way. It does not.

What pump's pages don't tell you, and we can't either: which way the bot leans on a given coin, whether it is trading this coin at all, and when it will stop. Unpredictable is the stated design.

Where you see Mayhem launches in clusterz

A copy setup can skip Mayhem tokens before they cost you.

The pill and the badge. In Trenches, a Mayhem launch wears a red pump pill on its logo, where an ordinary pump.fun launch has a green one. Its status line opens with a red Mayhem badge.

Hover it: "Mayhem launch: pump's bot trades it with 1B extra tokens it never bought, and can sell them all". Trending rows show the same red pump pill for where it trades.

Hide them. Turn on Hide Mayhem tokens in a column's filters, under Hide risky tokens. It works on Trending and the Map too.

While it is on, the active filter reads Hide Mayhem. In the Launchpads chips, a Mayhem launch counts as Pumpfun, so turning off the other launchpads does not hide it. See Filters per column.

How we count supply. We count a Mayhem launch's market cap and top 10 holder share on 2 billion tokens at launch, not 1 billion.

So MC reads double what an ordinary launch would at the same price, and the top 10 share is out of the real supply. See market cap vs liquidity.

Dead cards leave. A Mayhem launch whose market cap falls under 5 SOL leaves the board, from New and Soon as well as Graduated.

An ordinary curve cannot fall that low, so the rule only bites Mayhem tokens before graduation. On the day we set the rule, all but two of the dead graduates we found were Mayhem tokens.

Copies can skip them. Fast, together and dev copies have Skip Mayhem tokens under their guards: it skips tokens where pump.fun's own bot sells into the curve from the first seconds. It is off by default.

With it on, a token whose Mayhem status is not known yet when the copy triggers is skipped too. See Copy Trade.

How we tell: the launch itself says whether it is in Mayhem mode, and a pump.fun token with more than a billion in supply reads as Mayhem too. A token we could not read is not marked.

What we do: Hide Mayhem tokens on in New and Soon. If we trade one at all, we size it like a coin flip, because it is one.

Mayhem mode FAQ

What is Mayhem mode on pump.fun?

It is a launch setting where pump.fun's trading bot gets 1 billion extra tokens and trades the coin at random for its first 24 hours.

The creator turns it on at launch, and it cannot be added later. Unsold bot tokens are burned when the mode ends.

What is a Mayhem launch?

A pump.fun coin created with Mayhem mode on. It has 2 billion tokens instead of 1 billion and keeps its Mayhem tag for good. In clusterz it wears a red pump pill and a red Mayhem badge.

Is Mayhem mode a rug?

Not by design, and pump.fun says the bot is not trying to profit.

But the bot can sell tokens nobody bought from the curve, so the price can fall further than on an ordinary launch, and pump's own page warns some holders may be unable to sell into the curve. Treat it as a different, riskier game.

How long does Mayhem mode last?

pump.fun says the bot is active only in a coin's first 24 hours, and the mode ends early if the bot reaches its trade limit. After that the bot burns what it still holds and the coin trades like any other, minus whatever was burned.

How do I avoid Mayhem tokens?

In clusterz, turn on Hide Mayhem tokens in your filters, and Skip Mayhem tokens on your fast, together and dev copies. Elsewhere, look for the Mayhem tag on the coin's pump.fun page.
