Eminem, Twista, Or Rebel XD? The 5 Fastest Rappers In The World And Their Shocking WPM Records (2024 Update)

The question of who is the fastest rapper in the world is one of hip-hop’s most enduring and debated topics, and the answer is far more complex than a single name. As of December 15, 2025, the title is split between the verifiable official record holder and the legendary underground speedsters whose raw syllable counts remain unmatched. While the mainstream crown belongs to a certain Detroit legend, the all-time, raw-speed champion is a Chicago-based MC whose historical record has yet to be definitively broken. This article breaks down the three categories of speed rap—Official Record, Historical GWR, and Studio Legends—to give you the definitive, up-to-date answer.

The Official Champion: Eminem’s Unbeatable Guinness World Record

The most concrete, verifiable, and officially recognized speed record in hip-hop belongs to Marshall Mathers III, better known as Eminem.

Eminem: Fastest Rap in a No. 1 Single

Eminem's record is highly specific, which is why it stands as the official benchmark for the genre: the Fastest rap in a No. 1 single.

• Record: 225 words in 30 seconds.
• Song: "Godzilla," featuring the late Juice WRLD, from the 2020 album *Music to Be Murdered By*.
• Speed Calculation: This averages out to 7.5 words per second (W/s), which is an astonishing rate of approximately 1,500 Words Per Minute (WPM).
• Significance: The verse occurs in the third section of the song and secured Eminem a place in the *Guinness World Records* for this specific category.

Eminem is also known for a similar feat on his 2013 track "Rap God," where he delivered 9.6 Syllables Per Second (SPS) during a 15-second segment. His continued ability to perform these complex verses live, including a notable performance of "Rap God" in 2024, solidifies his status as a technical master.

The Historical Contenders: The Raw Syllable Speedsters

Before Eminem’s *Godzilla* verse, the "Fastest Rap MC" record was a fiercely contested category, often measured in total syllables delivered in a single, continuous take. This category is now complex, with some sources claiming the general record has been retired by the *Guinness World Records* organization.

1. Rebel XD (Chicago, USA)

Rebel XD (born Seandale Price) is the most frequently cited historical holder of the fastest rapper title, having broken the record multiple times. His records focused on the sheer number of syllables delivered in a short time.

• Latest GWR Claim (2007): 852 syllables in 42 seconds.
• Speed Calculation: This translates to approximately 20.29 Syllables Per Second (SPS).
• Biography Snapshot: Rebel XD is a Chicago-based MC who first achieved the record in 1992, then again in 1998, and finally in 2007. His flow is characterized by its clarity despite the extreme speed, a rare feat in speed rap.

2. Crucified (Texas, USA)

The Texas rapper Crucified is another MC who officially broke the record after Rebel XD, creating confusion over the definitive all-time title.

• GWR Claim (2013): 949 syllables in 49 seconds.
• Speed Calculation: This calculates to approximately 19.37 SPS, though one report cites a higher speed of 28.9 Syllables Per Second on his song "Power Up," which would be the fastest recorded speed ever.
• Biography Snapshot: Crucified, from New Braunfels, Texas, gained notoriety specifically for his record-breaking attempts, focusing his artistry on the technical aspects of speed and breath control.

3. NoClue (Seattle, USA)

Ricky Raphel Brown, known as NoClue, was the official *Guinness World Record* holder in the mid-2000s, cementing his place as a pioneer of the speed rap movement.

• GWR Claim (2005): 723 syllables in 51.27 seconds.
• Speed Calculation: This equates to roughly 14.1 SPS.
• Biography Snapshot: Hailing from Seattle, NoClue's 2005 record brought the technical challenge of speed rapping into the mainstream conversation, influencing a generation of faster MCs.

The Studio Speed Legends and Technical Masters

While the GWR focuses on raw, measured speed, many of the most influential speed rappers are known for their consistent use of the double-time rap technique and complex rhythmic syncopation across entire tracks, not just a single verse. These artists are the true masters of "flow."

Twista (Chicago, USA)

Twista (born Carl Terrell Mitchell) is arguably the foundational figure of modern speed rap. His early work defined the double-time style, where a rapper delivers twice the number of syllables per beat (BPM) of the instrumental.

• Signature Speed: Twista has been clocked at speeds ranging from 11.2 to 12.8 SPS on tracks like "Mista Tung Twista" and "From Da Tip of My Tongue."
• Impact: He popularized the style, making it a staple of the Chicago hip-hop scene and influencing countless artists who came after him.
• Recent Activity: Twista remains active in the industry, often featured on tracks where his unique speed flow is still a major highlight.

Tech N9ne (Kansas City, USA)

The independent rap mogul Tech N9ne (born Aaron Dontez Yates) is renowned for his ability to seamlessly transition between different tempos and flows, including his signature rapid-fire delivery.

• Signature Speed: While not officially measured for a record, Tech N9ne's verses often exceed 10 SPS, particularly on tracks like "Midwest Choppers" and "Worldwide Choppers."
• Influence: His label, Strange Music, became a hub for technical rappers and "chopper" artists, a subgenre defined by its extreme speed and complex rhyme schemes.

Busta Rhymes (New York, USA)

Trevor George Smith Jr., or Busta Rhymes, is a veteran known for his theatrical, high-energy performances and his use of rhythmic variation, including blistering speed.

• Signature Speed: Busta Rhymes demonstrates incredible versatility, but his fastest verses are often compared to the best in the business, with some sections hitting over 11 SPS.
• Notable Work: His verse on the remix of "Look at Me Now" alongside Lil Wayne and Chris Brown is considered one of the most iconic speed rap verses of the 2010s.

Krayzie Bone (Bone Thugs-N-Harmony)

As a founding member of the legendary group Bone Thugs-N-Harmony, Krayzie Bone was instrumental in blending rapid-fire delivery with melodic harmonies, creating a unique sound.

• Signature Speed: The group's style, often referred to as "Cleveland-style," is a masterclass in combining fast, multi-syllabic rhymes with singing, setting a standard for speed and musicality.

The Technical Breakdown: WPM vs. SPS

The debate over the fastest rapper often boils down to a technical difference: Words Per Minute (WPM) versus Syllables Per Second (SPS).

Words Per Minute (WPM): This metric is favored by *Guinness World Records* for certain categories (like Eminem's). However, it can be misleading in rap, as a single word can have one syllable ("the") or four ("dictionary").

Syllables Per Second (SPS): This is the preferred measurement for most hip-hop analysts because it provides a more accurate measure of the *rate of speech*. A higher SPS indicates a greater density of sound delivered in a short time, which is the true measure of a rapper's technical speed and breath control. The historical records by Rebel XD and Crucified are based on this metric.

Conclusion: Who is the Undisputed Fastest Rapper?

As of the current date, the title is best described with nuance:

1. The Official GWR Holder (Specific Category): Eminem (7.5 W/s or ~1,500 WPM on "Godzilla"). This is the only official, modern, and verifiable record from the *Guinness World Records* organization.
2. The All-Time Raw Speed Champion: Rebel XD or Crucified. While the category is murky, Crucified's claimed 28.9 SPS on "Power Up" is the highest figure ever cited, making him the strongest non-official contender for the raw speed title.
3. The Most Consistent Studio Master: Twista. His pioneering work in the double-time technique and consistent speed across decades of music make him the genre's most influential speedster.

The pursuit of speed continues to push the boundaries of vocal performance, driven by technical innovators like Logic (who hit 11.7 SPS on "100 Miles & Running"), Ab-Soul, and the mysterious Pøn-3. The true winner is the listener, who gets to experience these breathtaking displays of lyrical athleticism.
