Pump.fun has turned memecoin creation into a process that takes seconds and costs almost nothing. Its native token, PUMP, has become one of the sector's most debated assets because it combines two things that rarely coexist: real, measurable platform revenue and a multi-billion-dollar class action lawsuit. Understanding Pump.fun means understanding how Solana's memecoin market actually works today, and why a platform that generates substantial revenue does not automatically produce a token worth holding. This guide covers the mechanics, the verifiable data, and the open questions. Nothing here constitutes investment advice.
What Is Pump.fun?
Pump.fun is a memecoin launchpad built on the Solana blockchain, launched in 2024 by Alon Cohen, Noah Tweedale, and Dylan Kerler, and operated by Baton Corporation, a UK-registered company. Its function is straightforward: anyone, with no technical knowledge and no identity checks, can create a token and make it immediately tradeable. That frictionless design has produced hundreds of thousands of tokens and made Pump.fun a central piece of Solana's on-chain activity.
How the Bonding Curve Works
The platform's core mechanism is the bonding curve, a mathematical function that determines a token's price based on the quantity already purchased. When a new token is created, there is no order book with buyers and sellers. Instead, a smart contract sells tokens at a price that rises automatically as purchases come in and falls as tokens are sold back. No initial liquidity is required, no market maker is needed, and that is precisely why launch costs are close to zero.
When a token reaches a certain market-cap threshold, it “graduates”: the accumulated liquidity is transferred to a real trading venue, historically Raydium and more recently PumpSwap, the in-house DEX developed by Pump.fun itself. The share of tokens that complete this journey is historically very small. That figure is worth keeping in mind: the structure rewards volume of attempts, not the survival of individual projects.
Where the Revenue Comes From
The revenue model is a transaction fee, historically around 1% on bonding-curve trades, supplemented by fees from PumpSwap and other platform products. At high volumes, a small fee on a very large number of transactions compounds into significant sums. According to a job listing published by Baton Corporation in June 2026 for a Chief Legal Officer role, the platform processes more than $300 million in daily volume and generated over $500 million in profit in the preceding year with a lean headcount. The official PUMP token dashboard showed, as of September 2026, an annualized revenue of approximately $468 million, or roughly $1.28 million per day on the 90-day average, per the platform's own disclosure.
Those numbers deserve a specific caveat. Pump.fun's revenue depends on speculative volume in the memecoin market, the most cyclical variable in crypto. The January 2025 peak, when monthly revenue exceeded $130 million according to on-chain data tracked by Dune Analytics, has not been repeated. In subsequent months the figure normalized significantly lower.
The PUMP Token and the July 2025 Sale
PUMP is the platform's native token. The public sale took place on July 12, 2025, at a fixed price of $0.004 per token, raised approximately $600 million in twelve minutes, and combined with the private placement brought the total to roughly $1.32 billion. US and UK investors were excluded from participation, a detail that on its own maps the regulatory perimeter the company operates within.
One point that the official documentation makes clear, and that many analyses overlook: PUMP confers no right to platform revenue and no right to any distribution. Any connection between platform revenue and token value runs exclusively through the buyback programme, not through any holder entitlement.
Buyback and Burn: How the Policy Changed
For approximately nine months, Pump.fun directed 100% of its revenue toward open-market buybacks of PUMP. On April 29, 2026, the company burned the entire accumulated stock in two on-chain Solana transactions, at a value of approximately $370 million, reducing circulating supply by around 36%. By proportion of circulating tokens, this ranks among the largest supply reductions ever recorded in crypto. At the same time, the policy changed: 50% of net revenue from bonding curves, PumpSwap, and Terminal was locked in an irreversible smart contract dedicated to buybacks and burns over the following twelve months, while the other half was allocated to product development, hiring, marketing, and potential acquisitions.
The rationale stated by co-founder Alon Cohen is instructive. Despite nine months of full-revenue buybacks and more than $1 billion in cumulative revenue, the token had spent much of 2026 below its launch valuation, a clear signal that the market did not credit the mechanism with the durability the company had expected. That is the central tension of the whole story: a buyback programme transfers value only if the market believes it will persist, and only if it is not offset by new supply entering circulation.
The Factor That Offsets the Burns: Unlocks
Here lies the structural tension of the token. While buybacks reduce supply, the vesting schedule expands it. In July 2026, approximately $86.5 million worth of vested PUMP was distributed across 121 wallets linked to team members and investors, per blockchain records, and the unlock schedule runs through 2029. Anyone evaluating this asset must watch two opposing curves simultaneously: how much is burned and how much is unlocked in the same period. Focusing only on the first produces a systematically misleading read.
The Legal Dispute
Pump.fun has faced, since 2025, a consolidated class action in the US District Court for the Southern District of New York: Aguilar v. Baton Corporation Ltd., case no. 1:25-cv-00880. The initial claim alleges the sale of unregistered securities: according to the plaintiffs, every token created through the platform constitutes an unregistered financial instrument, and the company collected hundreds of millions of dollars in fees on that basis. The case was subsequently expanded with allegations under RICO, the US racketeering statute, with treble-damage claims quantified by plaintiffs at approximately $5.5 billion. The amended complaint also named infrastructure participants, including entities linked to Solana and Jito. The allegations are contested and no merits decision has been issued.
On the regulatory front, in December 2024 the UK Financial Conduct Authority flagged that the platform was offering financial services without authorisation, and Pump.fun subsequently blocked access for UK users. In June 2026, the company posted a Chief Legal Officer vacancy with a base salary of up to $5 million, requiring direct experience with the SEC, CFTC, FinCEN, OFAC, FCA, and MiCA obligations. That job description is a fairly transparent signal of how the company itself assesses its exposure across three major jurisdictions.
Why This Case Matters Beyond Memecoins
Pump.fun is the clearest live test of three questions that concern the entire crypto sector. The first is whether a token can embed value without conferring rights: here the connection is voluntary and revocable, as the April 2026 policy change demonstrated. The second is whether a platform that provides neutral infrastructure is liable for how that infrastructure gets used. That is exactly the legal theory under examination in New York, and a ruling either way will have implications well beyond Solana. The third is where infrastructure ends and financial intermediation begins, the question that MiCA in Europe and the US regulatory framework are each trying to answer in different ways.
What to Check Before Forming an Opinion
Anyone who wants to assess this asset seriously should look at, in order: daily platform revenue and its 90-day trend, not an isolated peak; the ratio of tokens burned to tokens unlocked in the same month; the share of tokens that actually graduate relative to those created, as a measure of real demand quality; the status of the Aguilar proceedings and any trial date that gets set; and the regulatory position in the jurisdictions where the platform operates, keeping in mind that access is already restricted in several of them.
The most honest framing for Pump.fun is that it's a high-revenue, high-risk business at the intersection of crypto infrastructure and financial services regulation. The revenue numbers are real. The legal exposure is real. Whether the PUMP token captures any of the first while the second plays out is a question the market is still pricing, with no settled answer yet in sight.
