CoinVoice has recently learned that, according to Ember monitoring, pump.fun started to use its fee income to repurchase PUMP after issuing the token, instead of directly transferring it to Kraken for sale as before:

In the past 7 hours, they transferred 187,770 SOL (approximately 30.53 million USD) of fee income to the 3vkp...3WTi address and then purchased PUMP. They then transferred the purchased PUMP to the G8Cc...kqjm address for storage.

So far, they have used 111,953 SOL (approximately 18.34 million USD) to acquire 3.04 billion PUMP, with an average price of 0.006 USD. [Original link]
