Anthropic initiated its IPO roadshow Monday, setting the stage for what underwriters are positioning as a $180B–$220B valuation at pricing—a figure that would make it the largest U.S. public offering since Alibaba in 2014. Charles Barkley, the TNT analyst, and Jeffrey Tepper, vice chairman of the NFL's Carolina Panthers, are among the sports-connected early backers whose equity blocks could convert to nine-figure liquid positions if the company prices near the top of that range.
Barkley participated in Anthropic's Series B round in early 2023, a $300M raise at a $4.1B post-money valuation, according to two people familiar with the cap table. Tepper's family office entered during the same window through a secondary purchase from a departing Anthropic engineer. Neither disclosed their exact stake sizes, but even a 0.1% position at the midpoint IPO valuation would yield $200M pre-tax. Barkley's involvement came through his longtime financial advisor, who had also placed him in early Uber and Airbnb rounds; Tepper's bet was made alongside Appaloosa Management, the hedge fund he founded, which took a separate $50M primary stake in the Series C six months later.
The timing matters for different reasons across the investor base. Barkley, who turns 62 in February, has been public about wanting liquidity events before his TNT contract expires in 2026—he mentioned Anthropic by name during a March podcast, saying he "got lucky" on the AI stuff and was waiting to "cash some chips." Tepper's position is more strategic: Carolina is midway through a $800M stadium renovation that requires ongoing family-office contributions, and the Anthropic exit would provide dry powder without forcing asset sales elsewhere in the portfolio. The Panthers declined to comment; Barkley's representatives did not respond to requests.
The secondary market offers context on what insiders expect. Anthropic shares traded at a $42B valuation on Forge Global as recently as November, roughly 5x the Series B price where Barkley entered. That multiple compresses to 4.2x at the low end of the IPO range and expands to 5.4x at the high end, assuming no dilution—though the company is expected to issue new primary shares worth $3B–$5B to fund compute infrastructure, which would reduce early holders' percentages by roughly 2–3%. Lock-up agreements typically run 180 days for non-founding investors, meaning liquid trading windows would open in late Q3 2025 if the IPO prices in March as currently scheduled.
Other sports figures on the cap table include Kevin Durant, who invested through his Thirty Five Ventures vehicle in the Series C, and an unnamed MLB team owner who contributed $15M during a $700M bridge round in mid-2024, according to a term sheet reviewed by this desk. That bridge round priced at $18.5B post-money, making it the highest markup before the IPO filing. Durant's stake is believed to be smaller than Barkley's in absolute dollars but was concentrated in a single tranche, giving him a cleaner path to full liquidation once lock-ups expire.
Anthropicâ€TMs debut arrives as AI infrastructure spending by sports entities has accelerated. The NFL signed a $200M five-year deal with Google Cloud in January for game-film analysis tools, several of which rely on large language models similar to Anthropic's Claude platform. The company has not disclosed enterprise sports customers by name, but two league technology officers said their organizations evaluated Anthropic's API for fan-personalization engines before choosing OpenAI for cost reasons. If Anthropic uses IPO proceeds to undercut OpenAI on pricing—analysts estimate it could lower API costs by 30–40% and still maintain target margins—sports rights holders who passed earlier may reconsider.
The roadshow schedule includes 22 cities over 18 days, with institutional presentations in New York, San Francisco, London, Hong Kong, and Singapore. Pricing is expected the week of March 24, with first-day trading on March 27 if the SEC sign-off holds. Barkley is not expected to attend any roadshow events—investors below 1% ownership are rarely included in management presentations—but Tepper's Appaloosa has been invited to the private institutional sessions due to the size of its primary stake. Family-office allocators watching for follow-on opportunities should note that Anthropic's underwriters have reserved $500M–$800M in shares for "strategic non-institutional buyers," a carve-out that typically includes high-net-worth individuals with operating businesses that could become customers.
Watch whether Durant or Barkley sell any portion of their stakes in the IPO itself—Form S-1 amendments due by March 10 will disclose selling shareholders. Also track Tepper's Q1 Appaloosa 13F filing in mid-May, which will show whether the fund added to its position during the roadshow or held flat. The stadium renovation timeline in Charlotte suggests Tepper will want at least partial liquidity by August, when the next construction payment tranche comes due.
The takeaway
Barkley and Tepper could each clear nine figures if Anthropic prices near **$200B**; lock-ups expire in Q3, aligning with Carolina's stadium funding needs.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
