With UFC 238 taking place a week ago and Bellator 222 taking place this past weekend, the time was right to update the MMAOddsBreaker fighter rankings, which will be updated regularly moving forward. I will show how far up 
or down 
a fighter has moved, as well as whether a fighter had previously not been in the rankings (NR).
An explanation also will be offered for the more significant changes in the rankings.
Pound-for-Pound
| 1. Jon Jones | |
| 2. Henry Cejudo | 2 |
| 3. Daniel Cormier | |
| 4. Khabib Nurmagomedov | 2 |
| 5. Amanda Nunes | |
| 6. Tony Ferguson | 3 |
| 7. Max Holloway | 1 |
| 8. Robert Whittaker | 1 |
| 9. Demetrious Johnson | 1 |
| 10. Valentina Shevchenko | 4 |
| 11. Kamaru Usman | 1 |
| 12. Dustin Poirier | 1 |
| 13. Israel Adesanya | 1 |
| 14. Conor McGregor | |
| 15. Kyoji Horiguchi | NR |
Henry Cejudo jumps to number two pound for pound in the world after moving up a weight class and defeating my previously top-ranked bantamweight fighter Marlon Moraes, and doing it with an injured ankle, no less. Khabib hasn’t done anything wrong, but Cormier and Cejudo have both done incredible things moving up weight classes to defeat elite opponents. Tony Ferguson also jumps up a few spaces after handling Donald Cerrone and winning his 12th consecutive bout in the Octagon. Lastly, Valentina Shevchenko was so much better than Jessica Eye in her title defense, it wasn’t even funny. She is head and shoulders above the rest of her competition at women’s flyweight. Lastly, after being one of the best flyweights on the planet, Kyoji Horiguchi has cemented himself as one of the best bantamweights in the world as well with his victory over Darrion Caldwell.
Heavyweight
| 1. Daniel Cormier | |
| 2. Stipe Miocic | |
| 3. Francis Ngannou | |
| 4. Junior dos Santos | |
| 5. Curtis Blaydes | |
| 6. Alistair Overeem | |
| 7. Alexander Volkov | |
| 8. Derrick Lewis | |
| 9. Cain Velasquez | |
| 10. Blagaoi Ivanov | 4 |
| 11. Tai Tuivasa | 1 |
| 12. Shamil Abdurakhimov | 1 |
| 13. Marcin Tybura | 1 |
| 14. Alexey Oleinik | 1 |
| 15. Walt Harris |
Blagoi Ivanov takes the leap after earning a decision victory over a game Tai Tuivasa at UFC 238. Ivanov has won two consecutive bouts in the Octagon against Ben Rothwell and Tuivasa and he’s showcased above average boxing, durability and power. Tuivasa looked improved against Ivanov, but still couldn’t get the job done, which is a credit to Ivanov.
Featherweight
| 1. Max Holloway | |
| 2. Alexander Volkanovski | |
| 3. Jose Aldo | |
| 4. Brian Ortega | |
| 5. Renato Moicano | |
| 6. Zabit Magomedshapirov | |
| 7. Frankie Edgar | |
| 8. Jeremy Stephens | |
| 9. Mirsad Bektic | |
| 10. Yair Rodriguez | |
| 11. Josh Emmett | |
| 12. Chan Sung Jung | |
| 13. Patricio Pitbull | |
| 14. Arnold Allen | |
| 15. Calvin Kattar | NR |
Nothing crazy, but Calvin Kattar looked terrific, earning a knockout victory over previous #15 Ricardo Lamas, so I’m slotting him into Lamas’ old position.
Bantamweight
| 1. Henry Cejudo | NR |
| 2. TJ Dillashaw | 1 |
| 3. Marlon Moraes | 1 |
| 4. Aljamain Sterling | |
| 5. Rafael Assuncao | 2 |
| 6. Kyoji Horiguchi | 5 |
| 7. Peter Yan | 2 |
| 8. Jimmie Rivera | |
| 9. Pedro Munhoz | 4 |
| 10. Cody Garbrandt | 4 |
| 11. Dominick Cruz | 4 |
| 12. Cory Sandhagen | 2 |
| 13. John Lineker | 1 |
| 14. Cody Stamann | 1 |
| 15. Ricky Simon | 1 |
There was a ridiculous amount of turnover in the bantamweight division the past two weeks, none larger than Henry Cejudo making his debut in the division by earning a TKO over Marlon Moraes and winning the vacant UFC bantamweight championship. Aljamain Sterling stays near the top of the division after his victory over Pedro Munhoz where he showcased his improving stand-up skills. Kyoji Horiguchi cemented himself as one of the best bantamweights in the world by winning the Bellator bantamweight title and Peter Yan wasn’t great, but knocked down Jimmie Rivera twice en route to earning a decision victory at UFC 238.
Women’s Strawweight
| 1. Jessica Andrade | |
| 2. Rose Namajunas | |
| 3. Joanna Jedrzejczyk | |
| 4. Tatiana Suarez | |
| 5. Nina Ansaroff | |
| 6. Claudia Gadelha | |
| 7. Michelle Waterson | |
| 8. Weili Zang | |
| 9. Cynthia Calvillo | |
| 10. Tecia Torres | 1 |
| 11. Randa Markos | 1 |
| 12. Felice Herrig | 1 |
| 13. Alexa Grasso | 2 |
| 14. Cortney Casey | |
| 15. Xiaonan Yan | NR |
Karolina Kowalkiewicz drops out of my top 15 after her one-sided loss to Alexa Grasso, who moves up two places. The former title challenger just looks shopworn at this point in her career and has now lost consecutive bouts to opponents she would have defeated 2-3 years ago. Xiaonan Yan makes her top 15 debut after defeating former Invicta champion Angela Hill, her fourth consecutive victory inside the Octagon.
