Introduction
The sports card market continues to surge, and this week's Market Movers data features some truly eye-popping price increases.
The overall market is already having an extraordinary year, with the SCI 500 Index up more than 54% since January 1st. But even within that broader market rally, several individual players are seeing their cards explode in value over the last 30 days.
This week's list features a recently promoted Toronto Blue Jays prospect, a New York Jets wide receiver looking for a major bounceback season, a Seattle Mariners prospect making an immediate MLB impact, a WNBA superstar returning to the international stage, and a Chicago Cubs star putting together a potentially MVP-winning stretch.
From massive percentage gains on affordable prospect cards to major jumps on high-end rookie cards, there is plenty for collectors to watch.
Let's break down the Top 5 Sports Cards Heating Up by Sports Card Investor based on the latest market performance and pricing data highlighted through Market Movers.

With the MLB playoff races heating up and the NFL season approaching, collectors are closely watching players who could continue generating momentum.
The Top 5 Sports Cards Heating Up
5. Brett Bateman
Toronto Blue Jays center fielder Brett Bateman is making a major impact following his move from the Chicago Cubs.
Bateman was traded to Toronto just before the trade deadline and received his call-up to the Major Leagues only five days later. Through his first 21 games with the Blue Jays, he is hitting .321.
That kind of immediate production has quickly changed the perception of Bateman, who entered the season as a relatively under-the-radar prospect.
Now, collectors are taking notice. His prospect cards have experienced some of the biggest percentage increases on this week's list, including one card that has jumped nearly 600% in just 30 days.
Key Card Movements:
-
2025 Bowman Chrome Prospect Auto 1st (Raw): $6 → $30
-
2025 Bowman Chrome Prospect Auto Refractor /499 1st (Raw): $14 → $30
-
2025 Bowman Chrome Prospect Auto Gold Refractor /50 1st (Raw): $38 → $265
-
2025 Bowman Chrome Prospect Auto Purple Refractor /250 1st (Raw): $13 → $50
The biggest move belongs to the Gold Refractor /50, which has climbed approximately 597% over the last month.
Bateman's rapid rise from an under-the-radar prospect to an immediate contributor in Toronto has clearly caught the attention of baseball card collectors. His performance is translating directly into increased demand for his Bowman prospect cards.
4. Garrett Wilson
New York Jets wide receiver Garrett Wilson takes the No. 4 spot as collectors look ahead to what could be a major bounceback season.
Wilson enters 2026 healthy after a knee injury limited him to just seven games last season, ending his streak of three consecutive 1,000-yard campaigns.
Even during the shortened 2025 season, Wilson caught 36 passes for 395 yards and four touchdowns, showing that he could still produce when available.
Now healthy again, Wilson reportedly made plenty of highlight-reel plays during training camp while catching passes from quarterback Geno Smith. That has created renewed excitement around his potential heading into the 2026 season. The renewed optimism is beginning to show up in his sports card market.
Key Card Movements:
-
2022 Mosaic Green Rookie (PSA 10): $30 → $42
-
2022 Optic Downtown Rookie (PSA 10): $700 → $850
-
2022 Prizm Variation Rookie (PSA 10): $30 → $45
-
2022 Prizm Rookie Autographs (PSA 10): $143 → $185
-
2025 Absolute Kaboom Horizontal SSP (Raw): $340 → $522
The biggest question for Wilson's card market is whether his return to health translates into another elite receiving season. If it does, collectors who have already started buying could see even more momentum.
3. Lazaro Montes
Seattle Mariners right fielder Lazaro Montes finally received his highly anticipated call-up to the Major Leagues. The 21-year-old immediately showed the power that made him such an intriguing prospect.
In his MLB debut, Montes went 2-for-4 with a home run, two RBIs, two runs, and a walk. His performance also helped Seattle snap a five-game losing streak with a 9-6 victory over Boston.
His first career home run was especially memorable. Montes launched a 47-foot blast to dead center at Fenway Park. He also became Seattle's first player since Ichiro in 2001 to record multiple hits in his MLB debut. It didn't take long for collectors to react.
Key Card Movements:
-
2023 Bowman Chrome Prospect Auto 1st (Raw): $74 → $106
-
2023 Bowman Chrome Prospect Auto Speckle Refractor /299 1st (PSA 10): $350 → $492
-
2023 Bowman Mega Box Chrome Prospect Auto (Raw): $30 → $85
-
2023 Bowman Mega Box Chrome 1st (PSA 10): $40 → $57
His MLB debut has given collectors a reason to revisit his prospect cards, and the combination of youth, power, and immediate production could keep attention on his market.
2. Caitlin Clark
WNBA superstar Caitlin Clark is putting together a strong stretch for the Indiana Fever and earning another opportunity on the international stage.
Clark has continued to elevate her game during her third WNBA season. Before the league's break, she delivered back-to-back huge performances. She scored 37 points and 10 assists against Chicago, followed by 34 points and 12 assists against Connecticut.
Clark is now turning her attention toward her first senior FIBA Women's World Cup with Team USA after earning MVP honors at the World Cup qualifying tournament. The combination of her on-court production and international opportunity has created renewed momentum around her sports cards.
Key Card Movements:
-
2024 Panini Instant WNBA Draft Night Rookie (PSA 10): $181 → $247
-
2024 Prizm WNBA Rookie Variation (Raw): Under $15 → $20+
-
2024 Prizm WNBA Base Rookie (Raw): $17 → $22
-
2024 Prizm WNBA Rookie Variation (PSA 10): $238 → $305
-
2024 Prizm WNBA Base Rookie (PSA 10): $243 → $290
-
2024 Rookie Royalty Downtown SSP (PSA 10): $4,100–$4,200 → $5,000–$6,300
Her continued performance and growing international profile are giving collectors another reason to watch her market closely.
1. Pete Crow-Armstrong
Topping this week's list is Chicago Cubs outfielder Pete Crow-Armstrong, who has once again become one of the hottest names in the sports card market. Crow-Armstrong has been one of the most frequent names to appear on the Top 5 list over the past several months, and his latest stretch may be the most impressive yet.
The Cubs star erupted for his first career three-home-run game against Cincinnati, going 4-for-6 with six RBIs and four runs scored as Chicago cruised to a 17-5 victory. And he wasn't finished.
In the following game, Crow-Armstrong homered in his first at-bat and then added another home run in the ninth inning. That gave him five runs over two games and pushed his season totals to 38 home runs and 32 stolen bases. He is also providing elite center-field defense and leads Major League Baseball in WAR.
With his power, speed, defense, and overall production, Crow-Armstrong is emerging as a major favorite for the National League MVP award. Collectors have responded in a big way.
Key Card Movements:
-
2020 Bowman Draft Chrome DP Auto Blue Refractor /150 1st (PSA 10): $4,7500 → $15,725
-
2020 Bowman Draft Chrome 1st (PSA 10): $108 → $650
-
2024 Topps Home Field Advantage (Raw): $160 → $350

-
2026 Topps Series 1 All Kings SSP (Raw): $960 → $2,400
Crow-Armstrong's combination of power, speed, defensive ability, and MVP-level production has created an incredible surge across his sports card market. For collectors holding his cards, this is one of the most significant market runs of the year.
