Raonic endorses the Wilson BLX Blade 98 18x20 tennis racket, and uses LUXILON M2 Pro 1.25 16L strings.
In January 2013, Raonic became the first tennis player to endorse New Balance clothing and shoes, in a deal reported to be worth "US$1 million annually over a five-year term."
Roughly two and a half years later, this deal was extended "for the length of [Raonic's] career and beyond," and stipulates that New Balance will increase its support of the Milos Raonic Foundation.
The lifelong nature of this contract was described by Tennis Canada as "unique."

Since March 2014, Raonic has donned a sleeve on his right arm while playing.
At first, he wore a fisherman's sleeve to cover a rash he had due to an allergic reaction to massage cream.
This was replaced with an athletic compression sleeve, often colour-coordinated with his on-court apparel.
The sleeve is worn for comfort, and wearing it became a habit for Raonic.
The sleeve has become a distinctive part of Raonic's image, and has spawned a Twitter account.
The motto "Believe in the Sleeve" has become synonymous with Raonic in the media and among Raonic's fans.
Serena Williams described the sleeve as "super cool and different."

Raonic is represented by CAA Sports, a division of Creative Artists Agency.
His other sponsorship deals include Aviva (insurance), Canada Goose (apparel), Commerce Court (real estate), Lacoste (apparel), Rolex (watches), SAP (software), and Zepp (sports metrics).
