ChatGPT prediction for Callum Simpson vs Troy Williamson, 20 December 2025.
Callum Simpson is the logical pick here. He carries an unbeaten 18–0 record, significant height/reach advantage and home crowd momentum; pundit Eddie Hearn expects him to control distance and finish strong. The market pegs him as a heavy favourite at 1.14, which reflects his class and tactical edge over a shorter, aggressive Troy Williamson.
Williamson’s late‑round power and recent stoppage win make him a live upset at 6.26, but stylistically he must close a big reach gap and weather a tactical 12‑round plan in Leeds. For a $1 outcome bet aiming for steady profit, Simpson’s probability edge and title‑holder profile make backing him the smarter, lower‑variance play.

Gemini prediction for Callum Simpson vs Troy Williamson, 20 December 2025.
Callum Simpson enters this highly anticipated generational clash as a significant favorite, and for good reason. His undefeated 18-0 record, highlighted by a strong KO ratio and recent European title victory, speaks volumes. Simpson's imposing 6'3¼" frame provides a clear height and reach advantage over Troy Williamson, allowing him to control distance as predicted by Eddie Hearn, who sees Simpson finishing strong. Playing in front of a fervent home crowd in Leeds will only amplify his momentum.
While Troy Williamson has shown resurgence with a recent English title stoppage and former champion Calzaghe notes his aggressive "dogfight" potential, Simpson's technical prowess and physical dominance are expected to neutralize Williamson's late-round power. The odds of 1.14 for Simpson might not offer a huge payout on a $1 bet, but it reflects the overwhelming probability of his victory, making it the most reliable path to a profitable outcome in the long run by consistently backing the stronger fighter.

Claude prediction for Callum Simpson vs Troy Williamson, 20 December 2025.
Callum Simpson enters this bout with significant advantages that make him the clear favorite at 1.14. His undefeated record (18-0) and impressive KO ratio demonstrate his dominance, while his recent European title victory showcases his championship pedigree.

In the electrifying clash at Leeds' First Direct Arena, Callum Simpson enters as the towering favorite, his 6'3¼" frame and undefeated 18-0 record screaming dominance.

Qwen prediction for Callum Simpson vs Troy Williamson, 20 December 2025.
Callum Simpson enters this bout as a heavy favourite with odds of 1.14, reflecting his undefeated record and dominant physical attributes. Standing at 6'3¼", Simpson's reach and technical prowess should allow him to dictate the pace from range, particularly in the early rounds. His recent European title win showcased his ability to handle high-pressure scenarios, reinforcing his status as the man to beat.
Troy Williamson, however, is no pushover. Boasting odds of 6.26, he carries significant power and a reputation for late-round stoppages, as evidenced by his English title victory earlier this year. Promoter Eddie Hearn has warned of Williamson’s knockout threat, suggesting that if Simpson allows the fight to devolve into a brawl, Williamson’s aggression could turn the tide. That said, Williamson’s shorter stature may struggle against Simpson’s rangy style unless he can close the distance effectively.
The venue, First Direct Bank Arena in Leeds, adds another layer of intrigue. Simpson will enjoy robust hometown support, which often proves pivotal in high-stakes domestic clashes like this. The atmosphere could buoy Simpson while potentially unsettling Williamson, who must contend with controversy surrounding fan restrictions.
While Williamson’s resurgence makes him dangerous, Simpson’s size, undefeated streak, and technical acumen tilt the scales firmly in his favour. Backing Simpson at 1.14 aligns with both logic and momentum.
