If you ask what's next after the halving, I think now people are waiting for the new ATH price that Bitcoin can reach. Even though miners get lower rewards than before, if the price of Bitcoin can rise very high, they can make a profit. They will probably keep their Bitcoin for a while until the price of Bitcoin goes up.
Not everyone is waiting for a new ATH, perhaps a new ATH was already created before the halving so even if another ATH should be expected it will not happen anytime soon and there are still investors that are also waiting for a dip in order to acquire more Bitcoins so the expectation of everyone differs and not just waiting for a new ATH to happen besides there are still long term hodlers that are not interested in Bitcoin creating a new ATH again but they just want to continue hodling or better still expecting a dip for them to increase their portfolio the more.
Sure miners gets some advantage when the price skyrockets because at that point a lot of transactions happen from those that wants to withdraw their Bitcoins from exchanges and those selling their coins as well so the traffic they generates lead to high transaction fees for easier confirmation in a block which is beneficial to miners.
I'm not sure if ATH occurred before the halving. The price of more than $70k is not yet a new ATH because with the rewards received by miners have decreased, the price of Bitcoin should be able to reach above $100k. We have just passed the halving event and we have to wait again. It's the same as when the halving occurred several years ago where after the halving, the price decreased again and would start to rise after a few months. Those who are interested in holding Bitcoin for the long term, don't really think about the new ATH that will occur. They already have a target when they sell their Bitcoin.
Most people will sell their Bitcoin when it reaches higher than $70k, especially if the price of Bitcoin can reach $100k. They will immediately sell it to make a big profit. But everything will return to each person's plan.
Yes, the market will respond positively to this halving but we still have to be patient because it won't happen instantly. Maybe there will still be a few months away from a positive response and if there is a price movement later, we can start preparing with the selling price we want. We must be able to remain patient and wait until the price can rise higher.
No one knows if the market will respond positively or not but to the highest of my knowledge, the market is determined by itself whether it will be positive or not and it also depends on the demand of investors because basically, if the demand is high it affects the price positively but just as you stated, it requires patience before we can start experiencing positivity in the market just like when spot Bitcoin ETFs were approved, the approval didn't had any effect immediately but after some time we started experiencing significant increase in the price of Bitcoin which even led to Bitcoin creating a new ATH.
The market has already determined where it will go because now we are seeing a rather deep decline. Bitcoin price is now under $60k so we still have to be patient to see the price rise. Now is a good time to buy more Bitcoins so we can accumulate more Bitcoins. Looks like shortly there will be a surprise from the market

We better be prepared for what will happen in the market. Don't forget to increase the amount of Bitcoin you have before the price goes up. That could make you miss out on accumulating more Bitcoin at low prices.
