Netflix blocked Bitcoin-related sponsors from appearing on a pro boxer’s fight trunks and gear during a major event it streamed live, forcing last-minute changes days before the bout, according to Sazmining CEO Kent Halliburton.
Halliburton, whose company provides Bitcoin mining-as-a-service using renewable hydroelectric energy, detailed the incident in a statement shared with Bitcoin Magazine. The sponsorship involved welterweight fighter Justin Cardona‘s appearance on the undercard of the Jake Paul vs. Anthony Joshua fight card, held December 19, 2025, at Miami’s Kaseya Center. Netflix served as the exclusive broadcaster, estimating viewership between 20 million and 100 million.
Sazmining, Bitcoin lending platform LEDN, and a standalone Bitcoin logo secured placement on Cardona’s trunks in mid-October 2025. Sponsors were submitted by late October, meeting the October 31 deadline for approval and embroidery. Logos were produced, invoices paid, and Cardona promoted the partnership publicly on social media. No objections arose for nearly two months.
On December 12, 2025—one week before fight night—promoter Most Valuable Promotions (MVP), co-promoting with Netflix, informed Cardona’s team of a “secondary review” by Netflix. The decision banned all Bitcoin-related content from fight-night trunks, press conferences, weigh-ins, and other fight-week activities. Cardona could have faced potential fines for non-compliance. The rejection cited “Prohibited per our policy,” with no additional explanation.
Netflix’s sponsor guidelines, reviewed by Halliburton, prohibit categories such as weapons, drugs, tobacco, political ads, sexually explicit content, and “speculative financial products.” Examples under the latter include get-rich-quick schemes, pyramid schemes, credit repair services, and payday loans. Bitcoin receives no explicit mention. Financial services appear in a “restricted” category requiring case-by-case approval, alongside alcohol, insurance, and gambling.
Other sponsors in restricted categories cleared the process without issue. An insurance firm backing Cardona gained approval. Polymarket and Draft Kings, two well-known betting sites, enabling real-money wagers on elections, sports, and cultural events, featured prominently on the broadcast—including stream branding and a main-event fighter displaying related merchandise on camera. Both of these platforms involve speculative financial elements and gambling, yet encountered no restrictions.
The ban compelled Cardona to replace custom-embroidered trunks at his own expense, disrupting preparations for what he called the biggest fight of his career. “In the ring, I fight for every round because time is scarce and every punch counts. Bitcoin is the same way—there’s a fixed supply, no one can inflate it away. I took a lot of pride in having Bitcoin companies on my trunks,” Cardona stated.
Halliburton highlighted the inconsistency, emphasizing Bitcoin’s institutional growth by 2026. Spot ETFs from BlackRock and Fidelity have drawn billions in inflows, publicly traded companies hold Bitcoin on balance sheets, and nations discuss adding it to reserves. The U.S. government has debated a Strategic Bitcoin Reserve. “It’s unbelievable that Bitcoin and Bitcoin companies continue to be censored,” Halliburton said, calling the reversal “incoherent” given Netflix’s guidelines and approvals for similar sponsors.
He urged Netflix to clarify its stance: If Bitcoin faces a blanket ban, it should appear explicitly in guidelines to avoid misleading athletes and businesses. Platforms set their own rules, Halliburton acknowledged, but demanded consistent, upfront application—especially after initial silence implied approval.
The incident illustrates ongoing hurdles for Bitcoin firms pursuing mainstream visibility through sports and media partnerships, despite the asset’s maturation into a $2 trillion class with regulated financial products.
For Bitcoin businesses like Sazmining, the episode reinforces the need for promoters aligned with Bitcoin’s principles. Cardona’s next fights prioritize such environments, potentially amplifying Bitcoin’s exposure in combat sports.
