AI infrastructure firm CoreWeave's ( CRWV ) deal to buy Core Scientific ( CORZ ) will raise the valuation floor for bitcoin (BTC) mining stocks but is unlikely to be replicated, Wall Street bank JPMorgan ( JPM ) said in a research report Tuesday.

"Much like the company’s first HPC deal with CoreWeave ( CRWV ) announced last summer, the terms and purchase price appear to be a one-off," analysts Reginald Smith and Charles Pearce wrote.

CoreWeave ( CRWV ) said Monday it had agreed to buy Core Scientific ( CORZ ) in an all-stock transaction valuing the bitcoin miner at about $20.40 per share, based on recent closing prices.

The bank's analysts noted that Core Scientific ( CORZ ) closed at around a 25% discount to the deal terms the day the takeover was announced. Given the year-end projected close, the analysts said this seemed appropriate.

B.Riley downgraded Core Scientific ( CORZ ) from buy to neutral with an unchanged $17 price target, the broker said in a research report Wednesday.

The investment firm said its price target takes into account the volatility in CoreWeave ( CRWV ) shares and the 6-month projected close for the deal.
