One Venue Now Does 44% of All Solana DEX Volume: How the Pump.fun Ecosystem Took Over the Chain
Solana's decentralized exchanges are having a loud week, and when we pulled the volume data to see who was actually driving it, one name dwarfed everything else. PumpSwap, the automated market maker built by Pump.fun, is handling about 43.6% of all Solana DEX volume by itself, more than five times the next-biggest venue. Add Pump.fun's bonding curve and the memecoin machine accounts for close to half of every dollar traded on Solana's DEXs. This is no longer a memecoin sideshow; it is the main event.
Reading DefiLlama's live data, Solana DEXs did about $1.84 billion in the last 24 hours, and Solana volume jumped more than 50% on the day. Of that total, PumpSwap alone did $803 million. The entire rest of the ecosystem, Orca, Meteora, Raydium and the long tail, splits the remainder. When one app is doing nearly half the volume of an entire chain, it stops being a protocol and starts being the market structure.
Where Solana's volume actually goes
| Venue | 24h volume | Share |
|---|---|---|
| PumpSwap (Pump.fun AMM) | $803M | 43.6% |
| Orca | $155M | 8.4% |
| Manifest | $119M | 6.4% |
| GoonFi | $108M | 5.9% |
| Meteora DLMM | $102M | 5.5% |
| Raydium | $84M | 4.5% |
| Pump.fun (bonding curve) | $68M | 3.7% |
| Pump.fun ecosystem (AMM + curve) | $871M | ~47% |
How the funnel became the market
The dominance makes sense once you follow the pipeline. Pump.fun launches memecoins on a bonding curve; when a token gathers enough buying, it graduates, and PumpSwap is where it lands to keep trading. By building its own AMM instead of sending graduates to Raydium, Pump.fun captured both ends of a memecoin's life: the launch and the afterlife. Every token that makes it now feeds volume straight back into the same company's venue. That vertical integration is why one ecosystem can out-trade the rest of Solana combined.
What the concentration means
Two readings, and both are true at once. On one hand, it is real, sticky activity: PumpSwap volume is traders actually swapping, not a vanity metric, and it shows Solana's retail engine is running hot again after a quiet stretch. On the other, it is concentration risk dressed as a boom. When nearly half a chain's DEX volume depends on the fortunes of one company and one asset class, a cooling in memecoin appetite, or any problem at Pump.fun, would leave a hole no other venue is currently sized to fill. A chain that looks liquid can be liquid in one place.
What to watch
Three things. First, whether PumpSwap's share keeps climbing or mean-reverts as memecoin heat cycles, since this snapshot caught a day when Solana volume jumped over 50%. Second, whether the established AMMs, Orca, Raydium, Meteora, claw back graduated-token flow or cede the memecoin lane entirely. Third, how much of the PumpSwap volume is durable versus reflexive churn around a handful of trending tokens, which is the difference between a new market structure and a temporary spike. For now, the number is the story: one venue, 44% of a chain.
Data note. Solana DEX 24-hour volume ($1.84B), the per-venue breakdown (PumpSwap $803M, Orca $155M and so on) and Pump.fun's bonding-curve volume ($68M) were read by DEXTools News from DefiLlama's public data on July 28, 2026, and rounded; the ~47% ecosystem figure combines PumpSwap and the bonding curve. Volumes and shares move continuously. This is information, not financial or trading advice.
Frequently asked questions
How much of Solana's DEX volume is PumpSwap?
Reading DefiLlama on July 28, 2026, Solana DEXs did about $1.84 billion in 24 hours and PumpSwap alone did roughly $803 million, or about 43.6%, more than five times the next-biggest venue (Orca at 8.4%). Adding Pump.fun's bonding-curve volume, the Pump.fun ecosystem accounts for close to 47% of all Solana DEX volume.
Why does PumpSwap dominate Solana?
Pump.fun launches memecoins on a bonding curve, and when a token graduates it moves to PumpSwap, Pump.fun's own AMM, to keep trading. By building its own AMM rather than routing graduates to Raydium, Pump.fun captured both the launch and the afterlife of every memecoin, so successful tokens feed volume straight back into the same venue.
Is Solana's DEX volume concentration a risk?
It cuts both ways. The volume is real trading activity, not a vanity metric, and shows Solana's retail engine running hot. But when nearly half a chain's DEX volume depends on one company and one asset class, a cooling in memecoin appetite or any problem at Pump.fun would leave a gap no other venue is currently sized to fill.
What are the other major Solana DEXs?
After PumpSwap, the largest venues by 24-hour volume were Orca (~$155M, 8.4%), Manifest (~$119M), GoonFi (~$108M), Meteora DLMM (~$102M) and Raydium (~$84M). None individually exceeds about 9% of the chain's DEX volume, which is what makes PumpSwap's 44% share so striking.
