Do you think they will buy 40000 BTC per week on average? I guess they will dump a similar amount once they see that the demand has decreased a little. If they continuously buy BTC through OTC deals or from exchanges, we will see a massive ATH this year. I don't know what could be the ATH, but if stats are true, then we may hit 150K this year.
That's the trillion dollar question

So far, they show no signs of slowing down, and there is enough money in these companies to be able to buy more than 40 000 BTC per week, which of course depends on their clients, who obviously consider Bitcoin a very desirable investment. Just imagine what can give you more than 100% profit in just 1 year or less and you will understand why so much is invested in Bitcoin, especially now that there is a very easy way for those who previously did not want (or did not know) how invest in BTC.
BlackRock is not only a company that operates in the US, they also have offices in about 70 countries around the world, and operate in about 100 countries. Regardless of the fact that the interference of such companies may have bad consequences for Bitcoin (in the long term), there is no doubt that they have raised that same Bitcoin to a completely new level where it has never been before.
