What bundled supply means#
Bundled supply is the share of a memecoin's tokens bought at launch by a coordinated group of wallets, usually in the same block the coin was created. Splitting the buy across many fresh wallets hides that one group controls a large slice of the supply, which it can later sell into everyone who bought after.
How does a launch bundle work?
On Solana this is done with bundles: groups of up to five transactions that land together, in order, or not at all, sent through Jito's block engine (Jito tips explained). A launcher puts the coin's creation and buys from fresh wallets into bundles, so a large slice of supply is held before any outside buyer can act.
Why split the buy across many wallets?
Presentation. One wallet holding 40% of a coin is an obvious warning; twenty wallets holding 2% each look like early community buyers. That is why terminals now show a "bundled" or "bundles" percentage on token pages, and why launch bundler tools are such a common search.
Bundling is not limited to pump.fun. Any launchpad where creation and the first buys can land in one block is open to it, including Raydium LaunchLab platforms such as LetsBonk and Meteora DBC launchpads, although some DBC launchpads use fee schedulers that make the first buys expensive.
Why it matters: a worked dump#
On a bonding curve, early tokens are cheap. That is exactly what a bundle exploits. Here is what the math looks like on pump.fun's published curve, with the 1.25% fee on every trade:
| What happens | Market cap after | Result |
|---|---|---|
| 1. Bundle buys 20 SOL across many wallets in the creation block | ≈ 78 SOL | Holds about 426M tokens, 42.6% of supply |
| 2. Outside buyers add 30 SOL over the next minutes | ≈ 196 SOL | They hold about 241M tokens |
| 3. Bundle wallets sell everything | ≈ 47 SOL | Bundle receives about 40.2 SOL: about +20 SOL |
| 4. Outside buyers' position | — | Their 30 SOL would now sell for about 8.6 SOL |

The bundle doubles its money and the chart falls about 76% from its peak. Nothing in that sequence required pulling liquidity, which a curve does not allow.
A supply dump does the same job, and it is the dominant form of rug pull on launchpad coins. How not to get rugged covers the other patterns, and whether pump.fun is safe at all.
Sniper bots also buy in the first block or two, independently of the creator. They are a different risk: snipers usually sell into the first momentum rather than coordinate a dump. Terminals usually report snipers and bundles separately.
How to check a coin for bundled supply#
- 1
Read the terminal's holder stats
Axiom, GMGN and similar terminals show the share held by the top 10 holders, the developer, snipers, insiders and bundles. Treat them as estimates: each tool uses its own heuristics.
- 2
Look at the first block
On an explorer, open the coin's earliest transactions. Many buys in the same slot as the creation, from wallets with no history, is the classic pattern.
- 3
Follow the funding
Bundle wallets are usually funded shortly before launch from the same source. A bubble map or an explorer's transfer history shows clusters that a holder list hides.
- 4
Check what the cluster holds now
A bundle that already sold is a different risk from one still holding 30%. The current share matters more than the launch share.
- 5
Watch for slow distribution
Bundle wallets often sell in small pieces into every buy rather than all at once, which shows as a chart that keeps fading under steady buying.
No single number decides it; what the cluster still holds does. A coin where linked wallets still hold a third of the supply can drop most of its market cap in a few transactions; a coin where they hold a few percent cannot. The full pre-trade routine, including authorities and Token-2022 extensions, is in the token safety checks.
What bundled supply changes about a trade#
- Your exit is shared with them. On a curve, every token they sell takes SOL out before you can. Size so that their full exit would not take you through your stop.
- Charts lie early. A bundle can create the look of organic buying in the first minutes. Volume and holder count are weak signals on a bundled coin.
- Graduation is not a clean slate. A bundle can push a coin through graduation and then sell on the new pool. See pump.fun graduation.
- A small residual is common. Many coins show a few percent bundled. The concern is concentration that is still held and large enough to move the price on its own.
How do you trade around a bundle?
Turn it into a number. Estimate what the linked wallets still hold, then ask what their full exit would do to the price from where you are buying.
In the worked example, a 42.6% bundle selling at once took about three quarters off the market cap. A 5% residual on the same curve would take roughly 13% off at $10k of market cap and about 26% at $50k, at $150 per SOL.
If that answer is larger than the loss you planned to accept, cut the size until it is not, or skip the coin. The position size calculator does the arithmetic.
Bundled coins on a Fullport account#
Fullport accounts trade real markets with real buyers. The conduct rules list the fake-chart coins that fall outside that: coins pumped by their deployer or by a bundle of linked wallets, wash-traded coins, rugs and honeypots. Sniping fresh launches, scalping and chasing momentum on genuine coins are all exactly what the account is for.
Coins are reviewed on-chain before an account is funded and before a payout is sent. The reason is simple: fills are priced from the real curve or pool, so the moves that count are the ones real traders could also have caught.
The checks above are the same ones that point you to real markets. Your cost is capped at the one-time evaluation fee of $120 to $300: trading losses come out of the simulated balance, never your wallet. Funded payouts send you 80% of profit in SOL, requested every 5 days (rules). Trade from the browser terminal or with Fullport Tap on the terminal whose bundle stats you already read.
Quick answers
- What is bundled supply in a memecoin?
- It is the share of a coin's tokens bought at launch by a coordinated group of wallets, usually in the same block as the coin's creation through Jito bundles. Splitting the buy across many wallets hides how much of the supply one group controls.
- How do I check if a pump.fun coin is bundled?
- Look at the bundle and insider figures in your terminal, then confirm on an explorer: many buys in the creation slot from fresh wallets, funded from a common source shortly before launch, is the usual pattern. Check how much those wallets still hold now.
- What bundle percentage is too high?
- There is no universal cutoff. What matters is how much linked wallets still hold and whether selling it would move the price through your stop. In our worked example, a 42.6% bundle selling everything cut the market cap by about three quarters.
- Is a bundled coin always a rug?
- Not always, but it gives a small group the power to dump on later buyers whenever they choose. Some launchers bundle to keep sniper bots out and then hold. You cannot tell intent from the chain, so treat a large held bundle as a risk to size around.
