Pump.fun Lets Memecoins Trade Against Tokenized Stocks on Solana

Pump.fun Pushes Tokenized Stocks Into 24/7 Solana Trading

Pump.fun is blurring the line between memecoins and traditional markets.

The Solana launchpad has introduced “Custom Pairs,” allowing anyone to create a token paired with tokenized stocks, crypto majors, metals, and other assets. The initial rollout supports 93 asset pairs through xStocks and Sunrise.

Twenty new stock tokens have also gone live through Sunrise, issued by Backpack Securities. The list includes Boeing, Alibaba, Costco, Dell, IBM, Johnson & Johnson, Lockheed Martin, Reddit, Rivian, Shopify and UPS.

Backpack says the tokens are redeemable 1:1 for underlying shares and can be transferred to traditional brokerages.

Memecoins Can Now Trade Directly Against Stocks

The mechanics are designed to make tokenized equities part of crypto-native trading rather than isolated investment products.

A Pump.fun creator can now launch a token against assets such as NVDAx or TSLAx instead of using SOL or a stablecoin as the quote asset. Trading fees can also be paid out in the paired token.

Custom Pairs carry the same Pump.fun bonding-curve and Pumpswap protocol fees as standard launches. Half of all revenue generated by Custom Pairs will flow into a programmatic PUMP buyback-and-burn contract.

Creators can charge between 0.05% and 1%, or opt for a cashback model that returns trading fees to users. That combination gives Pump.fun a direct economic incentive to increase trading around tokenized real-world assets.

The Model Depends on Volume Staying High

Not everyone is convinced the economics will endure.

Decentralized finance (DeFi) commentator Ignas warned that stock-and-memecoin models built around fees become fragile once speculation cools.

“If volume dries up, payouts & buybacks disappear,” he wrote, arguing that the incentive to hold such tokens weakens rapidly when trading activity falls. He pointed to Coinbase’s 2021 cycle, when quarterly trading volume fell roughly 74% within a year, and suggested memecoin activity could decline even more sharply.

The warning matters because Pump.fun’s PUMP buyback mechanism now depends partly on continued turnover in these new markets.

AMC-Robinhood Feud Shows the Regulatory Fault Line

The launch also comes just days after a public clash over tokenized equities on Robinhood Chain.

AMC CEO Adam Aron demanded Robinhood stop offering an AMC-linked token, arguing that the product was not authorized by the company and did not provide normal shareholder rights. Robinhood CEO Vlad Tenev responded by asking Adam what the concern was, due to Robinhood’s tokenized equities structure.

Robinhood documents described its Stock Tokens as debt securities offering economic exposure rather than direct ownership. Backpack, by contrast, says its new Solana stock tokens are backed and redeemable 1:1.

Still, the broader question is the same: crypto platforms are moving equities into programmable, 24/7 markets faster than traditional market rules were designed to accommodate.

Pump.fun has now pushed that experiment one step further by letting anyone build a memecoin market directly on top of them.
