The Defiant reported that Pump.fun has introduced Custom Pairs, allowing creators to launch memecoins paired with tokenized stocks, wrapped Bitcoin, and metals. This update brings Solana in line with Robinhood Chain's model, which previously drove significant volume in tokenized equities. The new pairs are routed through Sunrise and xStocks, with twenty specific stocks like Boeing, Alibaba, and Nvidia now available for trading.
Fees from these custom pools follow the standard 1.25% structure, with half of the revenue directed to a PUMP buyback-and-burn contract. Creator fees range from 0.05% to 1%, paid in the quote asset, while a Cashback option allows rewards to be shared with traders. Liquidity data shows Wrapped ETH holding $3.07 million, while Nvidia and Circle tokens hold over $1 million each.
The first pools launched in Wrapped BTC, with reserves between $3,200 and $3,800, though no stock-quoted launches appeared by 5 p.m. ET. Pump.fun noted that these pairs offer deeper liquidity and lower fees than other venues, despite the source observing thinner books than SOL or USDC pairs. The tokenized stock market is valued at $2.93 billion, with xStocks accounting for $631.2 million of that total. PUMP traded at $0.004287 by Wednesday evening, down 0.4% over 24 hours.
How the market reacted
Whalio's own Binance spot order flow for PUMP, measured when this story was written up on 9 September 2026. Not the outlet's figures.
Whalio data shows PUMP trading at $0.004317 with a 24-hour buy ratio of 50.3%, indicating a balanced market. The 1-hour buy ratio of 47.2% and 4-hour ratio of 48.0% are both below the daily average, suggesting short-term selling pressure is outweighing buying. Volume deltas reflect this imbalance, with -$293,302 in the last hour and -$684,635 over four hours. However, the 24-hour volume delta remains positive at +$194,199, showing that buying has been stronger over the full day. The Cumulative Volume Delta closed at -$393,490, indicating that aggressive selling has recently increased. Spot volume reached $35,681,153 with 263,849 trades, confirming active participation despite the recent dip.
The latest daily buy ratio of 50.6% sits at the 63rd percentile of the last 322 days, against a median of 49.3% - ordinary for this coin.
Was that an ordinary day?
The same Binance spot measurements for PUMP, averaged over the days leading up to the story.
Over the preceding week, PUMP experienced a 1.4% price decline with volume at 1.02x the average. The 7-day average buy ratio was 50.7%, slightly higher than the current 24-hour reading of 50.3%. This represents a 0.4 point drop from the weekly average, signaling a slight shift toward neutrality. Net buying occurred on only 3 of the past 7 days, contrasting with the 15 hours of net buying in the last 24 hours. The 8-day volume delta totaled +$7,964,175, showing that cumulative buying has outweighed selling over the longer term. This suggests the recent short-term dip is a minor fluctuation within a generally stable weekly trend.
