As of August 2018, Jacobs is ranked as the world's third best active middleweight by The Ring magazine, the Transnational Boxing Rankings Board and BoxRec. He is particularly known for his exceptional punching power, with an 82.8% knockout-to-win ratio, and is stylistically considered an all-around fighter with good movement and hand speed.

In February 2018, after weeks of speculation, it was officially announced that Jacobs would fight Polish boxer Maciej Sulęcki (26-0, 10 KOs) on April 28 at the Barclays Center in New York City on HBO. On March 30, the WBA elevated the fight to be an eliminator for their middleweight title. Jacobs won 116-111, 117-110 and 115-112 on three judges' scorecards.

On April 27, the IBF ordered Gennady Golovkin to defend his title against Ukrainian contender Serhiy Derevianchenko (12-0, 10 KOs). This came after the Golovkin vs. Alvarez rematch broke down and Golovkin decided to fight Vanes Martirosyan on May 5. The IBF allowed Golovkin to fight Martirosyan as long as he would fight Derevyanchenko afterwards. On June 6, Golovkin was stripped of his IBF world title due to not adhering to the IBF rules. The IBF granted Golovkin an exception to fight Martirosyan although they would not sanction the fight, however told Golovkin's team to start negotiating and fight mandatory challenger Derevyanchenko by August 3, 2018. The IBF released a statement in detail. On June 25, ther IBF ordered a purse bid to take place for Jacobs vs. Derevyanchenko on June 11. On July 20, according to Ringtv, the fight would take place for the vacant IBF middleweight title on November 10, 2018 at the Nassau Veterans Memorial Coliseum, Uniondale, New York.

Jacobs was engaged in negotiations with WBC, IBF, IBO and WBA (Super) middleweight champion Gennady Golovkin through 2016.

WBA president Gilberto Mendoza confirmed in an email to RingTV that a deal had to be made by 5pm on December 7 or a purse bid would be held on December 19 in Panama. Later that day, the WBA announced a purse bid would be scheduled with a minimum bid of $400,000, with Golovkin receiving 75% and Jacobs 25%. Although purse bids were announced, Loeffler stated he would carry on negotiations, hopeful that a deal would be reached before the purse bid. On December 17, terms were finally agreed and it was officially announced that the fight would take place at Madison Square Garden in New York City on March 18, 2017. The fight would be shown on HBO PPV.

In the fourth round, Golovkin dropped Jacobs with a short right hand along the ropes for a flash knockdown. Jacobs recovered, but Golovkin controlled most of the middle rounds.

According to Compubox punch stats, Golovkin landed 231 of 615 punches (38%) which was more than Jacobs who landed 175 of 541 (32%). Jacobs thought he had won the fight by two rounds and attributed the loss due to the potential big money fight that is Golovkin vs. Canelo Álvarez. Jacobs also stated after being knocked down, he told Golovkin, "he'd have to kill me." In the post-fight interview, Golovkin said, “I’m a boxer, not a killer. I respect the game.” Before revenue shares, it was reported that Golovkin would earn at least $2.5 million compared to Jacobs $1.75 million.
