It's either:
1. They buy power from existing rigs. However, the price is not the only thing they'll need to consider, but also if these pools would cooperate with them and sell them their service. Or,
2. They buy their own nodes, which they would need to make 101% of the current network node size, which would be too much expensive compared to the benefit they'll gain.

Those are some good points. In regards to being too expensive, is it fair to say that a company would spend any amount to save their companies business? So let's bump that spend to $100,000,000 (100 million USD) per top bank. Budget of $100,000,000,000 (10 Billion USD).
Banks such as HSBC have been fined 1.9 Billion USD and it hasn't hurt them. 100 million USD isn't going to do much to their profits.
J.P Morgan gets fined every 2-3 years averaging over 100 million USD.
Barclays similar amount to J.P Morgan.
Bank Fines:
Bank of America $76.1 Billion USD
JPMorgan Chase $43.7 Billion USD
Citigroup $19 Billion USD
Deutsche Bank $14 Billion USD
Wells Fargo $11.8 Billion USD
RBS $10.1 Billion USD
BNP Paribas $9.3 Billion USD
Credit Suisse $9.1 Billion USD
Morgan Stanley $8.6 Billion USD
Goldman Sachs $7.7 Billion USD
UBS $6.5 Billion USD
Keep in mind that fines are Banks having to forfeit money "involuntary".
Imagine how much they'd spend to stay in business.
