Pump.fun has lowered its referral revenue share to 37.5%, the platform confirmed, a cut that lands alongside the expiration of its 4x boost program. Creators will take home 62.5% less from the same referral fees than they did before the change.
The reduction doesn't touch the total pot of referral revenue — it changes how that pot is split. Where the boost program temporarily multiplied what referrers earned, the new baseline resets the payout to a smaller slice. Pump.fun says it will keep distributing all app revenue through rewards.
What the 37.5% share actually means
Referral programs on token launchpads work like a kickback: a creator or affiliate brings in trading activity, and the platform routes a portion of the fees generated back to them. Pump.fun's referral share now sits at 37.5%.
The number matters most for people who built audiences around the platform's boost window. During the 4x program, the same referral volume produced four times the reward. With that multiplier gone and the base share set at 37.5%, the effective payout drops by 62.5% for identical activity.
That's not a rounding error for full-time referrers. It's the difference between a program that pays for itself and one that needs another reason to keep promoting.
The 4x boost ends, and the math changes
The timing is the story here. Pump.fun didn't just trim a percentage in isolation — the cut coincides with the end of the 4x boost. Anyone who joined during the boost period saw inflated payouts that were never meant to be permanent.
The boost functioned as an acquisition tool: pay more to bring referrers in, then normalize. The normalization is what's happening now. For creators who treated the boosted rate as the real rate, the reset will feel like a pay cut even though the underlying fee flow hasn't changed.
Pump.fun hasn't framed the move as a pullback. Its stated position is that all app revenue continues to flow through rewards, which suggests the platform wants to keep the referral engine running even at a lower share. Whether 37.5% is enough to hold referrers is the open question.
Why referrers might stay anyway
A referral share only matters if there's revenue to share. Pump.fun's pitch rests on volume: as long as the app generates fees, 37.5% of a large number can still beat a bigger percentage of a small one.
That logic puts the burden on the platform's activity levels. If trading holds up, the lower share is a smaller paycheck, not a dead end. If activity cools, referrers are absorbing a cut at the worst possible time.
Creators now have a straightforward calculation to make. The boost is gone, the base rate is 37.5%, and the only variable left is how much referral fee volume they can drive. Some will reprice their promotional efforts; others will look for better terms elsewhere.
What Pump.fun hasn't said
The platform confirmed the new share and the boost's end but didn't attach a timeline for future changes. There's no word on whether 37.5% is a floor or a step toward something lower.
For now, the practical deadline is immediate: every referral fee earned from this point forward settles at the reduced rate. Creators who want to gauge the real impact should watch their next payout cycle rather than the announcement. The number that lands in their account will tell them more than any program description.
