Spencer Dinwiddie, the 26-year-old point guard for the Brooklyn Nets, has made headlines by tokenizing his own NBA contract on the Ethereum blockchain, using security token platform Securitize as a digital transfer agent. The initiative, launched on January 13, 2020, disregards explicit warnings from the NBA that such a move could result in a ban from the league.
Tokenization Details: $13.5 Million Upfront for Accredited Investors
Dinwiddie is selling 90 tokens called SD8 (Professional Athlete Investment Tokens, or PAInTs), each priced at $150,000. These tokens are available only to qualified accredited investors who meet SEC and legal standards. Purchasers cannot sell or trade the tokens for one year. The offering effectively allows Dinwiddie to receive $13.5 million upfront from his three-year, $34.4 million contract with the Nets, akin to a business loan. The three-year bond pays 4.95% base interest monthly, with the full principal returned at maturity in a bullet payment.
Initially, Dinwiddie planned to offer investors dividends if he opted out of his contract in the final year and signed with another team or renegotiated with the Nets. However, the NBA considered this a form of gambling and pressured him to remove that feature. After protracted discussions, Dinwiddie retained the core tokenization structure. To sweeten the deal, he promised to take eight backers to the All-Star weekend in Chicago if he is selected for the game.
NBA’s Strong Opposition: Citing Collective Bargaining Agreement
The NBA first expressed displeasure in September 2019, citing the Collective Bargaining Agreement (CBA) which states that “no player shall assign or otherwise transfer to any third party his right to receive compensation from the team under his uniform player contract.” Despite the threat of a ban, Dinwiddie—who describes himself on Twitter as “a tech guy with a jumper”—proceeded with the launch. “I understand the league’s concerns, but this is fundamentally a financial innovation, not gambling,” he told media outlets.
Industry Reactions: From Praise to Criticism, Justin Sun Inquires
The announcement sparked a firestorm on social media. Some praised it as a pioneering way for athletes and fans to engage, while others criticized the accredited investor restriction, calling it “wack” and “bullshit in legacy markets.” Tron CEO Justin Sun publicly asked how to get his hands on the tokens. Messari CEO Ryan Selkis wrote in his January 13 newsletter: “I’m a net buyer of tokenized athletic contracts as a precursor to widespread ISA adoption, and view the Dinwiddie bonds as merely the first in a coming slew of high-profile contracts that leverage a much more efficient technology (crypto) than previous attempts.”
When Crypto and Sports Collide: Not a First
This is not the first intersection of professional sports and cryptocurrency. In 2014, the Sacramento Kings became the first pro sports franchise to accept bitcoin for tickets and merchandise. Portuguese soccer team Benfica followed suit in June 2019. English Premier League teams Wolves and Newcastle United have struck kit sponsorship deals with crypto platforms like Stormgain. Boxing champion Manny Pacquiao launched a merchandise-backed token (the “pac” token) in August 2019. Dinwiddie’s platform, Dream Fan Shares, states on its website that it is “actively working to bring additional athletes, artists, and influencers onto the platform.”
The token sale window runs until February 10, 2020. It remains to be seen how many accredited investors will participate. Regardless of the outcome, Dinwiddie’s bold move has opened a new frontier for athlete financing and challenged traditional sports league regulatory frameworks.
