Used car market in the US is valued in the $150B range. So something like that could possible have some affect.

The housing market in the US though is on a different level. $8-9 trillion, so I don't think any one player is going to even make the smallest of differences unless they are focusing in specific markets and maybe manipulating just that area.

That’s the value of the entire stock.

But that’s not the inventory that is being traded at any point of time.

The vast majority of housing in the US sits in a single family without switching hands for probably decades. So the actual market is probably 20-30 times smaller, and so a single major player is far more capable of having an influence on pricing.

Besides, housing is not a national market. A buyer does not usually decide that they want to own a house and then scour the entire country to find houses they could live in.

They usually decide a place they want to live in, and then look at a much smaller market within that area. So even if a single entity cannot impact the national market, they could definitely impact local markets.

This is because of 2008. People are just now getting out of being underwater.

Like insider trading it doesn’t matter how large the market is, it’s a question of the individual transactions.

It’s not guaranteed that these companies will start intentionally misinforming people for profit, but that’s very much the risk.
