I don't understand the "inflating the market" part. They are buying and immediately relisting. They're not actually taking inventory out of the market. On average they sell for around the same price as they buy.
I think they will probably move into escrow and mortgage services soon and try to capture some of that market.
According to the video, they are buying and reselling for more than they bought it for. If that inflated price gets sold, that becomes the new comp in the area. And if they keep on doing it, all the new comps will be inflated. And while doing so, they are collecting all the data and storing it in their databases which can be information that they can sell to third party to generate A LOT of revenue.
Being in the data engineering field, data providers make a ton of revenue. Especially when the data is clean and well formatted which Zillow/Redfin have the engineering power to do so.
