📈 The 5 BIGGEST Tennis Card Market Trends At The US OPEN!

In this episode of the Serving Slabs podcast, host Aaron analyzes the five biggest tennis card market trends emerging from the 2025 US Open tournament. The first trend centers on Elena Rybakina becoming the 30th player in WTA history to reach world number one ranking. Aaron notes that her PSA 10 triple relic sticker royalty auto card sold for just $51 in July 2025, but jumped to $250 as she achieved the ranking, with Aaron predicting PSA 10 versions could exceed $500. He emphasizes that while Rybakina may not hold the ranking long due to competition from Sabalenka and Coco Gauff, the achievement is significant for her career trajectory at 25 years old.

The second major trend is Ben Shelton's historic upset victory over Carlos Alcaraz in a five-set match, ending Shelton's 0-17 record against top-3 players. Aaron stayed up late watching the match end at 2:30 AM Central Time and describes it as one of the best of Shelton's career. This victory has generated significant market activity, with Shelton's rookie card from 2010 Golden Sapphires increasing from $225 to $950 between September 9 and 11, 2025. Aaron congratulates long-term Shelton collectors for their patience and notes that both Shelton and fellow American Frances Tiafoe have reached the semifinals, giving American men's tennis a genuine chance at winning the US Open.

The third trend involves Qinwen Zheng's impressive quarterfinal run following her return from elbow surgery. Aaron credits her with almost defeating Rybakina, noting she was "one backhand away" from winning. Her PSA 10 red sapphire rookie card, which had dropped to $1,237 in April following her injury announcement, has recovered to $2,750 as of September 7. Aaron frames her tournament as a much-needed comeback after her injury derailed her previous top-5 ranking status.

The fourth trend covers Arthur Fils, a 20-22 year old French player who entered as a lucky loser after failing to qualify. Despite losing in the round of 16 to Botic van de Zandschulp in a 5-hour-20-minute match, his purple sapphire auto card jumped from $13 in March 2025 to $120 (a 4 out of 10 graded version), representing over a 900% increase. Aaron views this as justified given Fils' strong performance and potential for future Grand Slam runs.

Aaron combines trends five and six to discuss Alex Michelsen and Iva Jovic. Michelsen reached the quarterfinals without losing a set until facing Tiafoe, where he served for a semifinal spot but made critical double faults leading to a loss. His geometric raw gold autograph increased from $25 in August to $60 by early September. Iva Jovic, despite losing to Coco Gauff in the round of 16, impressed in her earlier match against Ayala with 42 winners against 25 unforced errors. Her blue geo card increased from $72 to $200 following the Ayala match. Aaron emphasizes that both players, aged 18-21, demonstrated exceptional performance under high-pressure conditions at Arthur Ashe Stadium.
