negotiated path forward, Orsini Decl. ¶¶ 3-4. A credible threat of prosecution under a preempted

state statute causes irreparable harm. See Morales , 504 U.S. at 381.

Further, the harm to Robinhood’s reputation caused by the threat, the uncertainty

surrounding the cease-and-desist demand, and potential enforcement proceedings by the Division

is also irreparable, because it cannot be easily or quickly repaired. KalshiEx , 2025 WL 1218313,

at *7; see also Kos Pharms., Inc. v. Andrx Corp. , 369 F.3d 700, 726 (3d Cir. 2004). Robinhood

also stands to lose the goodwill of its customers, including its over 48,000 customers in New

Jersey. Mackenzie Decl. ¶ 17. This goodwill, once lost, cannot easily or quickly be regained,

even if Robinhood ultimately prevails in litigation, and the risk to goodwill therefore also

constitutes irreparable harm. KalshiEx , 2025 WL 1218313, at *7; see also GlaxoSmithKline LLC

v. Boehringer Ingelheim Pharms., Inc. 484 F. Supp. 3d 207, 226-28 (E.D. Pa. 2020) (holding that

company was entitled to preliminary injunction to avoid reputational harm and loss of goodwill).

Nor could Robinhood have avoided irreparable harm by continuing voluntarily to comply

with the Division’s cease-and-desist demand. Had it continued to comply, Robinhood would

have been forced to continue to forgo significant business in New Jersey, resulting in loss of

revenue. Mackenzie Decl. ¶¶ 16-17. These economic losses would be unrecoverable because

sovereign immunity bars Robinhood from obtaining monetary damages for the Division’s impact

on Robinhood’s business. See Alden v. Maine , 527 U.S. 706, 712-13 (1999). Damages that are

unrecoverable due to sovereign immunity constitute irreparable harm. See, e.g. , Temple Univ. v.

White , 941 F.2d 201, 215 (3d Cir. 1991) (“As to the inadequacy of legal remedies, the Eleventh

Amendment bar to an award of retroactive damages against the Commonwealth clearly

establishes that any legal remedy is unavailable and that the only relief available is equitable in

nature.” (internal citation omitted)); Cigar Ass’n of Am. v. City of Phila. , 500 F. Supp. 3d 428,
