Los riesgos legales y de mercado que enfrenta PUMP: una perspectiva bajista en medio de demandas en aumento

The PUMP cryptocurrency, once a symbol of retail-driven memecoin mania on the Solana blockchain, now faces a perfect storm of legal and market risks. A U.S. federal class-action lawsuit against Pump.fun-the platform behind PUMP-has escalated dramatically in 2025, with over 5,000 internal chat messages submitted as evidence of alleged collusion between platform staff, Solana engineers, and Jito Labs executives to manipulate transactions for profit according to reports. These revelations, coupled with on-chain analytics revealing extreme token concentration and MEV-driven price distortions, paint a dire picture for PUMP's future.

Legal Risks: A "Rigged Slot Machine" Exposed

The lawsuit alleges that Pump.fun created an unfair system where insiders exploited maximal extractable value (MEV) to reorder transactions during memecoin launches, effectively front-running retail investors as research shows. The submitted chat logs, described as "contemporaneous evidence of collusion," reportedly show real-time coordination to prioritize transactions for profit, leaving ordinary users to absorb inflated prices according to internal documents. This mirrors the plaintiffs' characterization of the platform as a "rigged slot machine," where 98.6% of the 14 million tokens launched on Pump.fun collapsed in value, causing $4–$5.5 billion in losses according to market analysis.

Legal precedents suggest courts are increasingly scrutinizing MEV practices. For instance, the U.S. Department of Justice's case against the Peraire-Bueno brothers-MIT graduates accused of using MEV bots to exploit Ethereum-ended in a mistrial in November 2025, underscoring the judiciary's struggle to adjudicate complex blockchain fraud according to legal analysis. Meanwhile, the SEC's recent no-action letters for digital asset projects indicate a pragmatic approach to regulation, but the Pump.fun case could force a reckoning if courts classify MEV-based manipulation as securities fraud according to regulatory updates.

Market Risks: On-Chain Evidence of Manipulation

On-chain analytics further validate the plaintiffs' claims. During Q4 2024, Pump.fun accounted for 71.1% of Solana's token mints and 40–67.4% of decentralized exchange (DEX) transactions according to on-chain data. Yet, fewer than 2% of these tokens transitioned to major DEXs, signaling a speculative "pump-and-dump" structure. The top 10 holders control 70% of PUMP's supply, creating a liquidity imbalance that disadvantages retail investors according to market analysis.

MEV exacerbates these risks. On Solana, MEV can capture up to 20% of transaction fees during high-volume periods, often at the expense of ordinary users according to blockchain analysis. Jito Labs' MEV infrastructure, allegedly used by Pump.fun, enabled insiders to gain priority execution, compounding the unfair advantage according to trading reports. This dynamic has already triggered a capital exodus: BONK.fun's market cap nearly doubled to $241 million following the lawsuit announcement, as traders sought alternatives according to market data.

Investor Behavior Shifts and Regulatory Uncertainty

The lawsuit has accelerated a broader shift in investor sentiment. Retail traders, once drawn to Pump.fun's low-barrier token creation, are now wary of its risks. Daily active users surged from 60,000 to 260,000 in 2024 according to on-chain data, but this growth appears unsustainable given the platform's legal exposure. Regulatory uncertainty looms large: while the SEC's current stance avoids overreach, the Pump.fun case could prompt stricter MEV regulations, particularly if courts rule that transaction reordering constitutes fraud according to legal analysis.

Conclusion: A Bearish Outlook

The convergence of legal, on-chain, and behavioral risks makes a bearish outlook for PUMP compelling. The lawsuit's inclusion of 5,000 internal chats-a rare level of transparency in crypto litigation-could set a precedent for holding platforms accountable for MEV-driven manipulation according to legal reports. Meanwhile, the token's structural flaws-concentration of supply, reliance on speculative trading, and Solana's MEV infrastructure-suggest a market primed for collapse. As investors flee to alternatives like BONK.fun, PUMP's value proposition erodes, leaving it vulnerable to a prolonged downtrend.

For now, the case remains a cautionary tale: in the absence of robust regulatory frameworks, memecoins like PUMP risk becoming collateral damage in the broader reckoning of blockchain's fairness.
