It was announced during Glory 26: Amsterdam, that Marcus would rematch Levin sometime in 2016.

He was expected to fight Shifu Yanzi at Hero Legends in Jinan, China, on 3 December 2014. Shifu was replaced by Li Bei, however, and Marcus defeated him by TKO in round one, scoring two official knockdowns.

Marcus won the -80 kg/176 lb tournament at Wu Ling Feng: Kunlun Fight 2 in Zhengzhou, China, on 16 February 2014. His semi-final match with Israel Adesanya was scored a draw after the regulation three rounds and so it went into an extension round to decide the victor, after which Marcus was given the nod by the judges. He then stopped Vehas TopKing with a knee to the body just over two minutes into the first round in the final.

He was expected to rematch Artem Levin in a fight for the WMC World Super-Light Heavyweight (-82.5 kg/182 lb) Championship at Monte Carlo Fighting Masters 2014 in Monte Carlo, Monaco, on 14 June 2014.

It was announced during the Glory 15: Istanbul broadcast that Marcus would be one of eight fighters competing in the Glory 17: Los Angeles - Last Man Standing middleweight (-84.8 kg/187 lb) tournament in Inglewood, California, US, on 21 June 2014. He drew Joe Schilling for the third time in the quarter-finals and floored his American rival with a flurry of punches in round two. He outworked Schilling for all three rounds however, the judges scored the match a unanimous draw to send it into an extension round to decide the winner. Marcus was docked a point by referee "Big" John McCarthy for dropping his mouthpiece numerous times and, now forced to go for the knockout, was caught by a counter right cross from Schilling in the last twenty seconds of the fight which left him unconscious on the mat and with the first loss of his professional career.

Marcus once again beat two opponents in one night on 10 January 2013 when he knocked out both Arthit Hanchana and Wang Anying at the Foshan China vs. Thailand event in Foshan.

He had been expected to face Steven Wakeling under Oriental rules at Glory 5: London on 23 March 2013 in London, England, but he was replaced by Eddie Walker in that fight in due to the Levin match coming just a week before.

In a close fight, Marcus defeated Dmitry Valent by split decision at C3: King of Fighters in Chengdu, China, on 27 April 2013. He was initially set to rematch Kaoklai Kaennorsing at Muaythai Superfight on 13 May 2013 but the event was moved back to 14 June 2013 and Kaoklai was replaced by Suriya Prasathinphimai.

He fought to a controversial majority draw with Chidi Njokuani on the Push Kick Promotions: Muay Thai World Stand Off 5 card in Las Vegas on 29 September 2013. Njokuani started the fight well, using footwork to control the ring, but Marcus soon got inside and began landing knees and elbows from the clinch. In round two, Njokuani was twice given time to recover from illegal strikes, an elbow to the back of the head and a low blow. Each time the fight continued, Marcus would begin to again work in the clinch and Njokuani repeatedly turned his back, so the referee decided to break the fighters continually. Marcus was docked a point by referee Tony Weeks for landing a second low blow in round three and the fight turned into a brawl towards the end. When it went to the judges, the bout was declared a majority draw with two judges scoring the bout a draw and one scoring the bout for Njokuani. Simon Marcus then took to the microphone, calling Chidi Njokuani a "bitch" for his unwillingness to fight in the clinch and questioning the judges knowledge of the Muay Thai scoring system. These post-fight comments led to a heated confrontation between Marcus and Chidi's brother Anthony as they scuffled back stage.

He outpointed Jiang Chunpeng in Foshan on 25 October 2013.

Simon Marcus utilized elbows and knees heavily as he outpointed Damian Bujan en route to a split decision win at Ultra Elite Fighters V: Argentina vs. The World in Buenos Aires, Argentina, on 15 December 2013 in a fight where the referee was often quick to break up the clinch. The match was also briefly halted during the fifth round after both fighters fell through the ropes.

In January 2012, he entered the top ten in the world rankings for the first time in his career, coming in at #9. On 25 February 2012, Simon Marcus and Joe Schilling went head to head in a bout to determine North America's top light heavyweight at Lion Fight Promotions: Battle in the Desert 5 in Las Vegas, Nevada. Both men agreed to a "winner takes all" scenario, meaning that whoever came out victorious would take 100% of the fight purse, and the fight ended as controversially as it began. In round one, Marcus tripped Schilling, sending his head slamming into the canvas. As Schilling returned to his feet, clearly hurt from the throw, Marcus stormed in and knocked him down with a left hook. He was able to beat the count but Marcus went on the attack again and knocked Schilling out with a right elbow soon after. Following the fight, Schilling's camp made the accusation that the sweep that Marcus used to daze him initially was illegal and appealed to the Nevada State Athletic Commission to have the bout result overturned to a no contest, which was rejected.

Having just established himself as the continent's premier nak muay at his weight class, he then earned his first world title shot and his long-awaited fight with Kaoklai Kaennorsing was set for 16 March 2012 in Bangkok, Thailand, with the vacant WPMF World Light Heavyweight (−79 kg/175 lb) Championship on the line.

It was close this time, with both men exchanging menacing shots. Marcus' knees and throws from the clinch would be the deciding factor, however, as he was awarded the majority decision (47-47, 48–47, 49–46).

Marcus moved up to #6 in the world rankings and was expected to face Artem Levin, widely considered the world's best light heavyweight kickfighter, for the Russian's WBC Muaythai World Light Heavyweight strap at Battle for the Belts in Bangkok on 9 June 2012. However, Marcus withdrew from the bout for unknown reasons and was replaced by Joe Schilling. Levin would then also withdraw.

Levin vs. Marcus was then pencilled in for The Battle of Champions 7: School vs. School event at the Luzhniki Stadium in Moscow, Russia, for the vacant WMC World Light Heavyweight (−79 kg/175 lb) title on 16 November 2012 but the event was cancelled.

The much-anticipated fight between Simon Marcus and Artem Levin was scheduled for the third time and set for 21 December 2012 in Ekaterinburg, Russia, and then 23 February 2013, before eventually settling on 15 March 2013 at Lion Fight 9 in Las Vegas with the inaugural Lion Fight Light Heavyweight Championship on the line.

With his profile now rising, Marcus was scheduled to face former Rajadamnern Stadium champion Kaoklai Kaennorsing in Anaheim, California, United States on 13 August 2011 but the bout fell through. He would then sign with the short-lived Muaythai Premier League, and debuted with a unanimous decision win over familiar foe Artem Vakhitov at the Muaythai Premier League: Round 1 in Long Beach, California, United States, on 2 September 2011. Another big fight then fell through for Marcus as he was expected to go up against L'houcine "Aussie" Ouzgni at the Muaythai Premier League: Round 3 in the Hague, Netherlands on 6 November 2011 but Ouzgni pulled out on short notice.
