I would not be surprised if he makes another purchase that might be classified as whale signal and thus influence the crypto market, mostly as BTC is expected to be halved next year. He is exposed to top information and has lots of wealthy friends with investments in cryptocurrency and the future prospects in general.
As far as I know, his prestige has faded since he was rumored sold his bitcoin, he lost faith by the community, and because of that, he try to increase his name again by creating controversy or news that make his name appear again on the community. He tries to create strife with Mark so his name is back again on top. But still no progress because the people have already grown up and not easily affected again by his words.
Yes, no one hears his words again. because people already know, entrepreneurs have many ways to get a lot of profits.
His reputation in the crypto market has greatly diminished as everyone sees his true purpose as self-seeking. But I believe people will continue to watch what he does, and he will still influence the crypto market. Cryptocurrencies are a speculative market, where pumping and dumping occur daily, so they need more influencers like Elon to enter the market. The more manipulation happens, the more people benefit, so Elon will always be the influencer in the market.
