As long as EM don't make any silly tweet after he sell some of his BTC like he used to do. After Amazon, then the Wallmart is hiring for a specialist position in Cryptocurrency will show us that the big company has realize Crypto has been a trend for all especially BTC. We know BTC is not a scam and really interesting invention which has changed new finance system mindset. As long as people are more and more in touch with BTC then mass use is unavoidable.
The market has fuds in different levels: personal fuds from influencers, KOLs. Institutional fuds (Tesla, JP Morgan, Grayscale, etc.) and governmental fuds (from China, the US., Russia, SEC, etc.)
The same for good news with future development, adoption, investment and so much others.
I don't think the market will be manipulated only by Elon Musk and he will not have a position as biggest influencer in the crypto market like now.
