If you try bookmarking the page, it currently says $5.1M, which was inserted by HN bookmarklet during submission, then manually edited to $5M to fit within the 80 character maximum. The sub-heading of the article says:
> In January 2020 I closed a $5.1M seed round, my first financing for my first company. I’ve closed another ~$6M since then. This is how I raised that first round.
Yeah, the h1 article title inside the page changed, but the actual "title" attribute that you see in your browser tab is $5.1M (hence the confusion, I assume).
