ETF buying is a bigger deal than the halving in the short-medium term.
>10k BTC are bought every day by ETF's vs. a reduction of 450 BTC per day due to the halving.
In the long run the issuance reduction has an impact but this time the ETF's drive price action much more.
That's the difference to previous cycles, where daily demand was much lower and hence the impact of the supply cut was more significant.
