Update 4/17/26: Topps released the odds yesterday for 2025-26 Bowman Basketball. This included the odds of course for the Bowman NBA & NIL GPK cards. Odds are listed separately for the NBA GPK cards vs. the NIL GPK cards. GPK cards are available as Chrome Refractors in Hobby, Jumbo, Value and Bulk Hanger packs. Red Refractors /5, and Suoerfractors 1/1 are available in just the Hobby, Jumbo, and Value packs. Here are the listed odds for each:
- GPK NBA Refractors
- Hobby 1:13,050
- Jumbo 1:4,379
- Value 1:43,586
- Bulk 1:10,000
- GPK NIL Refractors
- Hobby 1:16,288
- Jumbo 1:5,474
- Value 1:54,483
- Bulk 1:12,500
- GPK NBA Red Refractors /5
- Hobby 1:196,931
- Jumbo 1:95,784
- Value 1:980,680
- GPK NIL Red Refractors /5
- Hobby 1:270,780
- Jumbo 1:109,468
- Value 1:1,176,816
- GPK NBA Superfractors 1/1
- Hobby 1:722,080
- Jumbo 1:766,272
- Value 1:5,884,080
- GPK NIL Superfractors 1/1
- Hobby 1:1,083,120
- Jumbo 1:766,272
- Value 1:5,884,080
Odds on these are very long, there looks to be a lot of this product printed. Based on some very quick math here is how many GPK cards are inserted into each SKU:
- GPK NBA
- Hobby – 187
- Jumbo – 182
- Value – 134
- Bulk – 83
- GPK NIL
- Hobby – 137
- Jumbo – 146
- Value – 107
- Bulk -66
Again very quick math here, but this comes out to 117 each of the GPK NBA cards, and 111 each of the GPK NIL cards. Slightly more than the 100 each expected. But collectors should still probably expect only around 100 of each of the Refractors. 2025-26 Bowman Basketball is set to launch 4/22/26.

Yesterday via their social channels, Topps posted a teaser image for the upcoming Garbage Pail Kids x NBA collaboration. The upcoming 2025-26 Bowman Basketball set will contain a GPK themed insert set. The company showed the chrome GPK card of Utah rookie Ace Bailey. All artwork for the NBA GPK cards was done by longtime artist David Gross. In the post, Topps did refer to the card being a SP card. Now that Topps has acquired additional sports licenses the company is beginning to incorporate GPKs into those brands, much like they’ve done the last two years with Bowman Chrome Baseball. No other details around the GPK inserts has been announced by Topps, including checklist, odds, or release date. Bowman Basketball will include a mix of young NBA stars, along with top college players. Collectors should expect the GPK checklist to follow that same formula.
