How Fast Do Solana Meme Coins Rug? A 53-Position Paper Cohort

Where this data comes from

Correction — September 2, 2026: The prior execution label could imply real-capital execution. The 53 positions were mechanically paper-executed using observed live market prices between July 25 and August 2, 2026; no capital was deployed. See the full cohort methodology and limits.

Every token in the paper cohort had already passed the strategy's full safety gate: LP burned at graduation, mint and freeze authority revoked, no hostile Token-2022 extensions, holder concentration within limits, creator wallet not blacklisted. These were strategy-selected screening survivors, not a representative sample of tokens.

How fast Solana meme coins rug: the headline numbers

• The fixed strategy-selected paper cohort contained 53 mechanically paper-executed positions on freshly graduated Pump.fun tokens
• In that fixed paper cohort, 8 tokens were classified as rugs after passing the strategy's checks; this is a within-cohort share, not a population rug rate
• In that fixed paper cohort, 30 of 53 modeled positions (57%) had positive gross paper outcomes; the rest hit paper stops or decayed
• In that fixed paper cohort, median modeled time to rug classification was ~89 minutes from paper entry near graduation
• In that fixed paper cohort, 90th-percentile modeled time to rug classification was ~10.6 hours
• In that fixed paper cohort, median modeled hold across all positions was ~15 minutes

What does this mean if you trade the trench?

1. Screening filters scams; it doesn't eliminate them

The 8 rug classifications show that screening did not eliminate severe outcomes in this selected cohort. They do not establish a 15% post-screening rug rate for the broader market. Everything in the rug-spotting checklist remains worth doing, but no checklist gets risk to zero because a clean contract cannot stop insiders from dumping supply they secretly coordinate.

2. The first two hours are the kill zone

In the fixed strategy-selected paper cohort, half of the modeled rug classifications occurred within ~90 minutes of paper entry near graduation. This selected observation does not establish a universal risk window; later rugs remained possible, including a paper-cohort classification more than 10 hours after entry.

3. Size for a total loss

A rug can mean a near-total loss of position. Because the cohort does not establish a population incidence or executable return distribution, use position sizing that can withstand a total loss rather than anchoring to its 8-of-53 share.

4. Speed beats conviction

The fixed strategy-selected paper cohort's 15-minute median modeled resolution supports frequent monitoring within that workflow, not a universal holding rule. Set alerts on liquidity drops and top-holder movements, use a pre-committed exit process, and treat failed-sell reports from other wallets as urgent warnings.

What the rugs had in common

Post-mortems on the 8 rug classifications in the fixed strategy-selected paper cohort showed patterns the screening workflow now scores more conservatively:

• Copycat launches — tokens riding another coin's name/ticker within minutes of it trending. Rug factories A/B test narratives; the copies rug faster than the originals.
• Wash-traded volume — vendor volume numbers inflated by self-trading to look organic. High wash ratios trigger rejection in the screening workflow.
• Thin real liquidity — pools where a single mid-size sell moves price double digits. Thin pools make rugs cheap to execute.

All three are now part of MemeAssist analyzer scoring, alongside the contract-level checks and holder intelligence.

Methodology: how we measured rug speed

Paper entries were recorded near pump.fun graduation using observed live market prices; paper exits followed a mechanical take-profit / stop-loss / rug-detection ruleset with no manual overrides. “Rugged” means a classified terminal event — liquidity drained, insider supply dumped to near-zero, or sells blocked — not merely a drawdown. The strategy-selected sample is a fixed 53 positions over nine days, July 25–August 2, 2026. Paper execution does not capture failed fills, fees, slippage or market impact, so outcome figures are not executable net returns.
