      Before WILLIAM PRYOR, JULIE CARNES, and SILER, Circuit Judges.
    
      
       Honorable Eugene E. Siler, Jr., United States Circuit Judge for the Sixth Circuit, sitting by designation.
    
   WILLIAM PRYOR, Circuit Judge:

We certified the following question of state law to the Delaware Supreme Court:

Does the diminution in the value of a limited liability company, which serves as a feeder fund in a limited partnership, provide the basis for an investor’s direct suit against the general partners when the company and the partnership allocate losses to investors’ individual capital accounts and do not issue transferable shares and losses are shared by investors in proportion to their investments?

Culverhouse v. Paulson & Co., 791 F.3d 1278, 1281 (11th Cir.2015). The Delaware Supreme Court answered our question in the negative. See Culverhouse v. Paulson & Co., No. 349, 2015, slip op. 1, 2, 133 A.3d 195, 195, 196, 2016 WL 304186 (Del. Jan. 26, 2016). Based on its answer, we now affirm the dismissal of the complaint.

I.BACKGROUND

Hugh Culverhouse invested in Hedge-Forum Paulson Advantage Plus, LLC, a “feeder” fund that invested in Paulson Advantage Plus, L.P. When the latter lost $460 million on a bad investment, Culver-house sued its general partners for breach of fiduciary duty, gross negligence, and unjust enrichment. Culverhouse alleged that his claims are “direct” under Delaware law. The district court disagreed and concluded that his claims are “derivative.” The district court ruled that Cul-verhouse lacked “standing” under Article III of the Constitution and dismissed his complaint for lack of “subject matter jurisdiction.” The district court also denied Culverhouse’s request for jurisdictional discovery and dismissed his complaint without leave to amend.

On appeal, we concluded that the question whether Culverhouse’s claims are direct or derivative is “unsettled” in Delaware. Culverhouse, 791 F.3d at 1281. We certified the question to the Delaware Supreme Court, which held that Culver-house’s claims are derivative. Culver-house, slip op. at 7-8, 133 A.3d at 198-200. We must now resolve Culverhouse’s appeal.

II.STANDARDS OF REVIEW

We review the dismissal of a complaint de novo. See Lord Abbett Mun. Income Fund, Inc. v. Tyson, 671 F.3d 1203, 1206 (11th Cir.2012). We review the denial of jurisdictional discovery and the denial of leave to amend for abuse of discretion. See Reese v. Herbert, 527 F.3d 1253, 1262 n. 13 (11th Cir.2008).

III.DISCUSSION

The district court correctly dismissed Culverhouse’s complaint. Now that the Delaware Supreme Court has answered our certified question, we know that Culverhouse’s claims are derivative, not direct. His derivative claims fail because Culverhouse was never a partner of Paulson Advantage Plus, L.P. See Del. Code Ann. tit. 6, § 17-1002'.

Although the district court correctly concluded that Culverhouse’s claims are derivative, it incorrectly described this defect as jurisdictional. In his complaint, Culverhouse alleged that his claims are direct under Delaware law. Because his theory was “not ‘immaterial and made solely for the purpose of obtaining jurisdiction’ or ‘wholly insubstantial and frivolous,’” Black v. Wigington, No. 1510848, 811 F.3d 1259, 1262, 1270, 2016 WL 278918 (11th Cir. Jan. 22, 2016) (quoting Bell v. Hood, 327 U.S. 678, 682-83, 66 S.Ct. 773, 90 L.Ed. 939 (1946)), the district court should have accepted it as correct for purposes of jurisdiction, see Mr. Furniture Warehouse, Inc. v. Barclays Am./Commercial Inc., 919 F.2d 1517, 1520 n. 2 (11th Cir.1990). “[I]n reviewing the standing question, the court must be careful not to decide the questions on the merits for or against the plaintiff, and must therefore assume that on the merits the plaintiffs would be successful in their claims.” City of Waukesha v. EPA, 320 F.3d 228, 235 (D.C.Cir.2003) (citing Warth v. Seldin, 422 U.S. 490, 502, 95 S.Ct. 2197, 45 L.Ed.2d 343 (1975)). When the district court later concluded that Culverhouse was wrong and that his claims were derivative, its ruling should have been on the merits. See Lexmark Int’l, Inc. v. Static Control Components, Inc., — U.S.—, 134 S.Ct. 1377, 1387 n. 4, 188 L.Ed.2d 392 (2014); Bond v. United States, 564 U.S. 211, 131 S.Ct. 2355, 2362, 180 L.Ed.2d 269 (2011). That is, the district court should have dismissed Culverhouse’s complaint for failure to state a claim, Fed.R.Civ.P. 12(b)(6), not for lack of subject-matter jurisdiction, Fed. R.Civ.P. 12(b)(1). See Williamson v. Tucker, 645 F.2d 404, 415-16 (5th Cir.1981).

Nevertheless, this labeling error is harmless because Culverhouse’s complaint should have been dismissed. See McCallum v. City of Athens, 976 F.2d 649, 650 & n. 1 (11th Cir.l992). Because the complaint fails to state a claim, Culverhouse was also not entitled to jurisdictional discovery. See Chatham Condo. Ass’ns v. Century Vill., Inc., 597 F.2d 1002, 1011-12 (5th Cir.1979). And amending his complaint would have been futile. See Sibley v. Lando, 437 F.3d 1067, 1073 (11th Cir. 2005).

IY. CONCLUSION

We AFFIRM the dismissal of Culver-house’s complaint.
