What is a bundle on pump.fun, and how to spot one

On pump.fun a creator can launch a coin and buy it from many wallets in the same instant. To everyone else those wallets look like eager early buyers. They are usually one person holding a large share of the supply, waiting for you.

How a bundle looks on-chain

  • Several wallets buy in the first 3 seconds, often in the same block as the creation.
  • Similar amounts, fresh wallets, sometimes funded from the same source minutes earlier.
  • They keep holding together, then sell together.

Why it matters

In yeppo's data, coins with a launch bundle of 10% or more dumped 40% within ten minutes far more often (12 to 24% of the time) than coins without one (3%). Big bundles also push the price up fast at first, which is why they look attractive.

How yeppo shows it

Every read shows what the launch bundle still holds, what the snipers of the first 15 seconds still hold, and the biggest single wallet. When they hold enough to crash a push, yeppo never says Momentum.

Questions

Is every early buyer a bundle?

No. Snipers and fast traders buy in the first seconds too. A bundle is a group that acts as one: same moment, similar size, holding and selling together.

The bundle sold already. Is the coin safe now?

Safer on that one point: the bag that could dump at once is gone. The other checks still apply.
