The answer is no, they will not accept the ETF in the coming 23 days, but they will also not reject it, instead, they will delay it. And will extend the dates, in my opinion, they wanted to use this news or hype which will be created due to the approval of ETFs, as fuel to boost the BTC price up, upper than we all have expected. Like a bonus.
But, if we look at the long run and ask whether they will approve it or not, then I think they have no other option but to approve them all because they will have more benefit from these approvals, as exposure of BTC will increase and people who are not into BTC investment yet, will start to make investments and this will ultimately increase their (country) income via taxes and by other means. Overall, all they need is more investors, who can buy their shares.
Plus, we should not make SEC an entity that would have that much impact on the industry, I mean, there is no doubt that they do have an impact on the market, but we all should not make decisions according to them because they are just working in US and BTC is being used in worldwide, if they don't accept BTC ETFs then another country would approve that and then the investors will move to that country and all the profits will be theirs. And the US can not let that happen.
Who is "they"? Because that's not how SEC could operate even in theory. You are saying SEC is corrupted while they are literally one of the organisations created against corruption. I totally understand someone's mindset if they thought it as just another company that wants to make profits. But they don't need outside funding. They get all the money they need via US government, so they have insanely big budget. And organisations like SEC have to have full transparency and auditability about everything. So they are not going to play with bitcoin markets or hold bitcoin. That would be insane. I am guessing even the people who work there would be too afraid to hold it as if it would go up because of something SEC would do, they would get jailed for insider trading.
In theory, what you say is not wrong, but don't forget that human greed is bottomless. As you see, why do many billionaires with hundreds of billions of dollars like Elon still want to make more money every day while he will never be able to spend all that money until he dies? Furthermore, they are corrupt or they are trying to manipulate the market, they have no obligation to inform you, what evidence do you have to be sure that they are not corrupt or not invested in bitcoin?
In addition, there are many corruption cases in the government that take decades to investigate. Then, you know the truth, does it have any more meaning?
