Solana ($SOL) is flashing two on-chain cracks in the same two-week window: weekly DEX trading volume collapsed about 82%, and a key holder cohort began trimming its stake just as that drop unfolded. Dune and Glassnode data line the two events up almost to the week, with meme coin launchpads at the center.
The timing is the story. Here is how the pieces connect.
Solana DEX Volume Collapsed in Two Weeks
The drop is steep and recent. Per Dune data, total weekly DEX volume across Solana protocols stood near $104.3 billion in the week of May 11, with the DEX Meteora alone accounting for about $93.1 billion. Two weeks later, in the week of May 25, total weekly volume had fallen to roughly $18.8 billion, with Meteora down to $9.2 billion.
That is a decline of about 82% in two weeks, and it hit the largest venue hardest.

Meteora shed more than $80 billion in weekly volume on its own. The fall is broad rather than isolated, pointing to a drying up of the speculative flow that once defined Solana trading.
It also extends a longer slide, with weekly DEX volume on the network down more than 50% since January. The question is what drained the flow, and who reacted to it.
Meme Coin Launchpads Went Quiet
The answer sits with meme coins. Solana’s DEX volume has long run on a flywheel where launchpads mint new meme coins, traders chase them, and DEXes process the churn. That engine, where components even rivalled Ethereum, has stalled.
On-chain data shows new meme coin launches roughly halved in early 2026. The cooling launchpad activity and cutting the supply of fresh tokens to trade are visible. With fewer new narratives to chase, the speculative volume that inflated weekly DEX totals had nothing to feed on. Trading bot revenue likely fell alongside it.
The Meteora figures make the link concrete. A venue built around meme coin and launch churn does not shed more than $80 billion in weekly volume on a broad market dip alone.
It falls when the launches that generate the trades dry up. The collapse in DEX volume is, at its core, a collapse in meme coin speculation, and the timing of that collapse matters for what came next.
The Overlap: A Key Cohort Started Selling in the Same Window
Here is where the two datasets meet. Per Glassnode’s HODL Waves, a metric that groups supply by how long coins have stayed unmoved, the 1-year-to-2-year cohort held 16.049% of $SOL supply on May 21. By June 1, that share had slipped to around 15%.
That sell-down began on May 21, squarely inside the May 11 to May 25 window in which DEX volume collapsed. The two on-chain signals turned at almost the same time. This cohort holds coins bought into Solana’s 2024-to-2025 activity boom.
It is the same boom that ran on the meme coin volume now draining away.
The data does not prove the volume crash forced the cohort out, and the piece does not claim it did. What the data shows is a clean timeline overlap. As the activity that underpinned Solana’s trading economy fell off, a group of holders who had sat tight through that economy started letting go in the same window.
Whether the Solana DEX volume collapse is the trigger or simply a parallel symptom, the two are now bleeding together. And that is the question Solana’s next few weeks will answer.
