Brandon Jacobson (born November 14, 2003) is an American chess player who received the FIDE title of Grandmaster in 2020 at the age of 16. He previously held the International Master (2018) and FIDE Master (2017) titles. He is ranked the 36th best player in the United States. His highest rating was 2583 (in November 2024). Brandon's older brother Aaron Jacobson holds the title of International Master.

Chess career

In January 2020, Jacobson won the 2020 Charlotte Open in Charlotte, North Carolina, with a score of 7.0/9, half a point ahead of GM Cemil Can Ali Marandi, GM Akshat Chandra, GM Andrew Tang, GM Ulvi Bajarani, and IM Aaron Grabinsky. He earned his final GM norm and a $3000 prize.

Later in 2020, Jacobson participated in the 2020 US Junior Chess Championship. He ended the tournament with a 5.5 score and 4th in rankings.

In May 2024, Jacobson gained notoriety by playing a dubious opening (1.a4 and 2.Ra3 as White and 1...a5 and 2...Ra6 as Black) during a match against Daniel Naroditsky, defeating him (+37, -26, =6).

Editorial analysis

Why this record matters

“Brandon Jacobson” is worth following because a concise public description often conceals a longer documentary argument. Here, Brandon, Jacobson and American provides the most credible route into that argument.

Evidence profile

Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q59139044. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2003, 2020, 2018 and 2017.

Critical limits

A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
