Does this mean that tons of money could be invested in these - let's say a trillion dollars going long on bitcoin via cash settled futures - and the underlying price wouldn't necessarily go up at all? I always thought the play with bitcoin was to wait until the "dumb money" got in via financial institutions. But if the whales are just betting on the real price with cash settled futures, does that mess up my assumptions about supply/demand?

Let’s say the price of bitcoin is $10000. You want to go long using futures, so you start buying contracts. A few people will want to sell futures at $10000, but not for a trillion dollars. If you want to buy more futures, you will have to pay more. If you offer $11000 there will be more people willing to take the other side of the bet. And if the price of the underlying is still $10000 arbitrage is possible. I could buy one bitcoin for $10000 and sell you the future for $11000, pocketing $1000 no matter what the future price of bitcoin may be. That creates demand for bitcoin if there is huge demand for futures, pushing prices up.

The contracts would still involve real Bitcoin, the exchange would handle the Bitcoin side for the trader.

So I buy a future for 1 bitcoin in 10 days with a price of $10k. The future is cash settled, so in 10 days the exchange will give me [price of BTC] - $10k, or I can sell the future before then. Where does the bitcoin come in? Is the exchange required to hold bitcoin = to the net of all futures?

I’m guessing no fiat to crypto or vice versa; 1. That’s a taxable event. 2. Wouldn’t that lead to more financial scrutiny?

For CME (and perhaps NASDAQ) they are doing cash settlement instead of physical settlement of the Bitcoin since it would introduce significant overhead. They are going to use a reference rate called their "Bitcoin Reference Rate" which has a collection of exchanges that it uses to determine the spot price.
