OPINION
Appellant Robert E. Brennan petitioned the District Court for habeas relief under 28 U.S.C. § 2255 claiming that his trial and appellate counsels were ineffective. The District Court denied his petition. We granted Brennan’s request for a certificate of appealability under 28 U.S.C. § 2253(c)(1). Since Brennan has failed to demonstrate that he was prejudiced by his counsels’ allegedly deficient performance, we will affirm the District Court’s decision.1
To prevail on a claim of ineffective assistance of counsel, Brennan must demonstrate “(1) that his counsel’s performance was deficient; and (2) that he was prejudiced by it.” United States v. Lilly, 536 F.3d 190, 195 (3d Cir.2008) (citing Strickland v. Washington, 466 U.S. 668, 687, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984)). We *247need not decide whether Brennan’s counsels were deficient if it is clear that Brennan has not shown any prejudice. See Strickland, 466 U.S. at 697, 104 S.Ct. 2052 (“If it is easier to dispose of an ineffectiveness claim on the ground of lack of sufficient prejudice, which we expect will often be so, that course should be followed”).
Here, Brennan claims that his trial and appellate counsels were ineffective because they failed to invoke Apprendi v. New Jersey, 580 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000), at his sentencing and direct appeal despite his requests that they do so. Brennan, however, does not argue that an Apprendi challenge would have been successful before the trial or appellate courts. Instead, Brennan asserts that “[h]ad the Apprendi issue been preserved by Brennan’s trial and appellate counsel (as he requested), it is likely that the Supreme Court would have considered the issue just as the Court did in [Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004)]....” (Br. for Appellant at 20.) Therefore, to show prejudice, Brennan must demonstrate a reasonable probability that, but for his counsels’ deficient performances, the Supreme Court would have granted his petition for certiorari. See Strickland, 466 U.S. at 694, 104 S.Ct. 2052 (“The defendant must show that there is a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.”).
We recognize that to show prejudice, Brennan “need not show that counsel’s deficient performance more likely than not altered the outcome in the case — rather, he must show only a probability sufficient to undermine confidence in the outcome.” Thomas v. Varner, 428 F.3d 491, 502 (3d Cir.2005) (internal quotations and citations omitted). We also acknowledge that “[t]his standard is not a stringent one.” Id. Nonetheless, Brennan bears the burden of demonstrating prejudice. Fountain v. Kyler, 420 F.3d 267, 275 (3d Cir. 2005). In our view, he has come up short.
According to Brennan, the fact that the Court granted certiorari in Blakely two weeks after it denied his petition demonstrates a likelihood that the Court would have granted his petition had he preserved the Apprendi issue. We disagree. While Blakely concerned the post-Apprendi constitutionality of a state court’s sentencing procedure, see 542 U.S. at 299-301, 124 S.Ct. 2531, Brennan was subject to the federal sentencing regime. This is a significant difference. At the time it granted certiorari in Blakely, the Court exhibited no signs that it was also ready to consider Apprendi’s effect on federal sentencing. Indeed, Blakely explicitly disclaimed any applicability to the Federal Sentencing Guidelines. See 542 U.S. at 305 n. 9, 124 S.Ct. 2531 (“The Federal Guidelines are not before us, and we express no opinion on them.”). It was not until the following term that the Court demonstrated a willingness to confront the Apprendi issue that Brennan claims he would have raised had it been preserved. See United States v. Booker, 543 U.S. 220, 229, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005) (noting that in the Government’s petition for certiorari, it “ask[ed] us to determine whether our Ap-prendi line of cases applies to the Sentencing Guidelines, and if so, what portions of the Guidelines remain in effect”).
“[A] writ of certiorari is granted or refused in the exercise of a sound discretion.” Phila. & Reading Coal & Iron Co. v. Gilbert, 245 U.S. 162, 165, 38 S.Ct. 58, 62 L.Ed. 221 (1917). Its grant is a rare event.2 Here, Brennan can only speculate *248that, had he preserved the Apprendi issue, his direct appeal would have been among those select few. This is not enough to show prejudice. See Baker v. Barbo, 177 F.3d 149, 154 (3d Cir.1999) (holding that “totally speculative” arguments as to prejudice did not show a “a probability sufficient to undermine confidence in the outcome”). Therefore, we will affirm the District Court’s decision to deny Brennan’s petition for habeas relief.3
