Crypto on Trial: The $5.5 Billion Pump.fun, Solana & RICO Lawsuit That Could Redefine On‑Chain Liability

In one of the most consequential legal battles in the history of decentralized finance, a sprawling class‑action lawsuit has now fully unfolded in a federal courtroom in Manhattan, accusing the memecoin launchpad Pump.fun and key players in the Solana ecosystem of running what plaintiffs characterize as a coordinated, unlawful speculative scheme. What began as a narrower dispute over unregistered token trading has grown into an expansive complaint under the Racketeer Influenced and Corrupt Organizations Act (RICO) and U.S. securities law — with potential damages estimated between $4 billion and $5.5 billion.
 
The case is pending in the U.S. District Court for the Southern District of New York, where Judge Colleen McMahon recently granted plaintiffs leave to file a second amended complaint, a development that underscores the seriousness of the claims and offers a preview of what could be a precedent‑setting clash between crypto innovation and regulatory enforcement.

From Meme Coins to Multi‑Billion Dollar Claims

Pump.fun launched in early 2024 as a meme token launchpad on Solana, designed for rapid creation and trading of tokens with minimal friction. The platform’s ease of use — requiring little more than a name and image to mint a token — attracted millions of users, and hundreds of thousands of tokens were created in the process. According to filings, a vast majority of these assets collapsed to negligible value, leaving many retail participants at a loss.

The lawsuit, originally filed in January 2025 by investors who said they lost money on specific Pump.fun tokens, initially alleged violations of securities laws due to the unregistered sale of investment contracts. In July 2025, plaintiffs consolidated claims into a unified complaint and added federal RICO counts, dramatically intensifying the stakes.

Under RICO, plaintiffs are not merely arguing about a bad product but asserting that the defendants formed a coordinated “enterprise” engaging in alleged wrongdoing like wire fraud, securities fraud, unlicensed money transmission, and facilitating illegal gambling‑like activities. If the RICO components succeed, plaintiffs could potentially seek treble damages, which could push exposure toward roughly $15 billion.

Who’s Named and Why It Matters

The defendants encompass a mix of individuals and organizations connected to the platform’s creation and the Solana network’s broader infrastructure. They include:

An expanding list of defendants now named in the case ranges from Baton Corporation Ltd. (Pump.fun’s operator) and its founders to Solana Labs, the Solana Foundation, and senior figures from both entities. Co‑founders such as Anatoly Yakovenko and Raj Gokal, and executives including Lily Liu of the Solana Foundation, appear in the complaint.

Three young entrepreneurs behind Pump.fun’s operating company are named individually in their capacity as control persons. These founders, all in their early 20s, are alleged to have known roles in shaping the platform’s operations.

Importantly, earlier co‑defendants like Jito Labs and the Jito Foundation were voluntarily dismissed from the case in September 2025 after plaintiffs narrowed their focus, and no settlement was reported in connection with that dismissal.

What the Plaintiffs Allege

At the heart of the complaint is a narrative that Pump.fun wasn’t merely a neutral launchpad but part of a systematic machine that generated billions in speculative trading losses while extracting fees through every transaction.

Plaintiffs argue:

The platform’s design and mechanics — including instantaneous bonding curves that set token prices algorithmically — disproportionately advantaged insiders, bots, or privileged participants. There are claims that internal chat logs, now incorporated into the latest complaint, show discussions about technical mechanisms like validator behavior, transaction ordering, and priority execution paths that allegedly facilitated early access ahead of the public.

That the sheer volume of token launches, lack of transparent risk disclosures, and absence of identity verification created an environment akin to an unlicensed “digital casino,” where users essentially wagered funds on unpredictable price movements without adequate consumer protections.

And that Solana’s core design, marketed for high throughput and low fees, was knowingly leveraged rather than merely tolerated, constituting active technical coordination between Pump.fun and Solana infrastructure teams — a central point in the RICO enterprise theory.

Legal Theories Beyond RICO

Beyond the racketeering claims, the lawsuit resurrects traditional securities law arguments, asserting that many of the memecoins launched via the platform meet the Howey Test criteria for investment contracts: namely, that participants invested money with the expectation of profit in a common enterprise where that profit depended on the efforts of others.

Additionally, plaintiffs allege violations of consumer protection statutes under New York law (Sections 349 and 350), unjust enrichment, and unlicensed money transmission. Allegations in some reports even touch on broader concerns over illicit activity, although those aspects are not universally reported across sources.

Where the Case Stands

In December 2025 the court granted plaintiffs permission to file a second amended complaint incorporating newly surfaced evidence — including thousands of pages of internal communications — expanding the factual basis for the RICO theory. The deadline to submit this rewritten complaint was set for December 19, 2025, with subsequent briefing scheduled through early 2026.

Defendants are expected to respond with motions to dismiss, a key early battleground for whether these novel legal theories will survive judicial scrutiny. If they do, the litigation will move into a protracted discovery phase that could reshape the scope of liability for underlying blockchain infrastructure providers and app layers alike.

Why This Matters for Crypto

This lawsuit strikes at a foundational assumption widely held in the industry: that blockchains and protocol developers are akin to neutral technology providers rather than active market participants. Should any portion of the RICO or securities claims survive, the implications could extend far beyond Solana and Pump.fun — potentially impacting how meme tokens, launchpads, and decentralized finance platforms are regulated and litigated in the U.S.

That potential has already rippled through the market, prompting traders to explore alternative meme ecosystems and sparking discussions about legal accountability for core network developers.

At the same time, courts have recently exhibited caution in applying securities law to certain crypto market activities, as seen in other high‑profile cases. The evolving legal landscape underscores that uncertainty, but also that the cost of “neutral infrastructure” may no longer be assumed.
