Tom Aspinall's ongoing recovery from the eye injury that sidelined him after the October 2025 no-contest with Ciryl Gane has left the UFC heavyweight title picture unusually fluid heading into the second half of 2026. With an interim champion likely to emerge from the cluster of summer bouts, traders see a tight race among Serghei Spivac, Jailton Almeida, Ante Delija, and Waldo Cortes Acosta because each has shown recent momentum through wins over ranked opposition while the division lacks a single dominant force. Sergei Pavlovich and Derrick Lewis remain viable due to their power and experience, yet the bunched implied probabilities reflect how quickly a strong performance or setback in the next few months could shift the long-term outlook before the end of the year.
