Core Scientific has become one of the more charged setups in digital infrastructure this week — a 17% rally, three fresh analyst initiations in six days, and short sellers sitting on 21% of the float with no obvious exit pressure.
The options market is telling the clearest story about where sentiment has shifted. Call demand has surged to its most extreme bullish reading in the past year, with the put/call ratio dropping to 0.35 — roughly two standard deviations below its 20-day average of 0.41. That z-score of -2.01 sits near the 52-week low of 0.24, meaning options traders are positioned about as aggressively for upside as they have been at any point over the past twelve months. The move follows the stock's 17% week and a 2.3% close on Tuesday at $18.79. Peers confirmed the sector bid: KEEL and RIOT both rallied more than 26% on the week, HUT added 22%, while and each gained around 20%.
Short positioning tells a more complicated story. At 21% of the free float, short interest is genuinely elevated — but it has barely moved. The shares short ticked up less than 0.1% on both a one-day and one-week basis, and only rose about 2% over the past month. Borrowing costs remain near historic lows at 0.46%, and borrow availability is comfortable at 219% — more than two shares available in the lending pool for every one already borrowed. That availability figure has actually eased since mid-August, when it dipped below 180%. With 5.9 days to cover and no meaningful squeeze pressure visible in the borrow market, the short base looks entrenched rather than panicking — a significant wall of scepticism that the rally has not yet dislodged.
The Street is arriving late to the party but arriving in force. Three firms initiated coverage in the past six days alone: UBS opened at Buy with a $24 target on Tuesday, Wells Fargo launched at Overweight with a $28 target last Wednesday, and Rothschild took a more cautious Neutral stance with a $16 target — the only dissenting voice of the week. The broader consensus among 16 buy-rated analysts sits at a mean target of $34.35, nearly double the current price. Bulls point to CORZ's pivot into high-density AI and HPC colocation, including a 430 MW site near Dallas, as the structural growth driver that justifies a premium over pure-play Bitcoin miners. Bears flag the continued dependence on Bitcoin pricing and the risk that the colocation transition stalls. Factor scores back the momentum case: earnings surprise ranks in the 100th percentile, 90-day EPS momentum is in the 98th percentile, and analyst recommendation divergence — measuring how far the consensus leans bullish versus history — also ranks in the 98th percentile. The short score of 67.5 reflects that combination of high short interest and strong recent momentum.
One name on the activist register is worth flagging. Two Seas Capital filed a Schedule 13D on CORZ in August 2025 — a declaration of activist intent at 6.3% of the class. Their most recent institutional filing, however, shows them cutting from roughly 19 million shares to around 9 million (a reduction of 2.9 million shares as last reported for June 30). That puts their visible stake well below the original 13D level. As with all 13D/G disclosures, stakes are as-last-reported around the 5% threshold, and a holder dropping below 5% may exit without a further filing — so their current position is uncertain.
The next scheduled catalyst is earnings on November 2. The last two prints produced sharp immediate reactions: a 3.5% drop after the August release and a 12.6% decline the day after the July report, though that second event recovered to a 10% gain over the subsequent five days. With the stock up 17% in a week and call positioning at annual extremes, what happens to that short base of 21% of float — and whether it begins to unwind or holds firm — is the dynamic worth tracking into the November print.
