I don’t know what the grading market share rates were before CGC’s involvement, but I would be interested to see exactly where CGC is taking market share from. I recall the prevailing take from well-informed people when CGC launched was that it wouldn’t touch PSA, but could take the grading share of smaller companies like BGS and SGC.
Here are the market share statistics for the previous 3 years, numbers in millions of cards graded:
2022:
- PSA: 77.1% SHARE - 10.65/13.81
- CGC: 11.3% SHARE - 1.56/13.81
- SGC: 6.2% SHARE - .85/13.81
- BGS: 5.4% SHARE - .75/13.81
2023:
- PSA: 78.5% SHARE - 13.5/17.2
- CGC: 9.9% SHARE - 1.7/17.2
- SGC: 7.0% SHARE - 1.2/17.2
- BGS: 4.5% SHARE - .77/17.2
2024:
- PSA: 75.9% SHARE - 15.34/20.2
- CGC: 11.5% SHARE - 2.32/20.2
- SGC: 9.3% SHARE - 1.87/20.2
- BGS: 3.3% SHARE - .66/20.2
Interestingly, the past three years have seen PSA and CGC stay fairly consistent in market share, with PSA between 75-80% and CGC between 10-12%. The main trends have been a steady increase in SGC’s market share (now owned by PSA) and a steady decrease in BGS’ market share. I think this lends support to the idea that the lesser grading companies are mainly fighting it out for themselves in PSA’s shadow. They are certainly very viable, but their gains/losses in market share come at the expense of each other, not PSA.
Tl;dr CGC isn’t “flipping” PSA anytime soon, if they increase their market share it will likely be at the expense of other smaller companies.
