digg.com reported on 15 September 2026 that Memeburn says Pump.fun copied Stonk, but the fees work differently.

The outlet notes that while the features are similar, the economic structure varies between the two platforms.
How the market reacted
Whalio's own Binance spot order flow for PUMP, measured when this story was written up on 16 September 2026. Not the outlet's figures.
Pump (PUMP) is trading at $0.003518 with a 24-hour buy ratio of 49.8%, indicating a near-even split between buyers and sellers. However, the 1-hour buy ratio has dropped to 41.6%, suggesting that immediate buying pressure is fading compared to the longer-term trend. The volume delta reflects this shift, showing a net outflow of $248,531 in the last hour versus a smaller $14,853 outflow over four hours. The cumulative volume delta (CVD) for the day stands at -$473,196, confirming that sellers have dominated the flow over the full 24-hour period despite the balanced buy ratio.
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.
