| 6/16/26 | All 63 Wemby Rookie Prizm Cards Ranked by Return | One Victor Wembanyama rookie card. Sixty-three parallels. Every grade, every grader, tracked from first sale to today. Only on Slabnomics will you hear a ranking of all parallels by return percentage AND grader breakdowns. I broke down the entire 2023 Panini Prizm #136 rainbow to find which colors and which grades actually paid, and the answers cut against what the hobby repeats. The famous Silver underperformed. A PSA 9 beat the PSA 10 in a lot of parallels. Listen in for which p... | 34m 07s | ||||||
| 6/9/26 | Only 4 of These 1952 Topps Legends Beat the S&P 500 | Out of the 10 biggest names in 1952 Topps, only four beat the S&P 500 over 22 years. We pulled 9,720 real sales back to 2004, ran every PSA grade through three market cycles, and spoiler alert, the winner isn't the 1952 Mantle. Plus the first look at RRR, the risk-return ratio built to tell you which cards let you sleep at night. Full grade-by-grade breakdown at slabnomics.com. Keep Building.

| 6/2/26 | PSA: The Federal Reserve of The Hobby | PSA just halted all four of its value grading tiers. The hobby is calling it a failure. We're calling it something else. PSA just acted like a central bank. This episode breaks down why PSA controlling the supply of grades is the same lever the Federal Reserve pulls when it controls the supply of money. We map the full analogy, the dual mandate between volume and grade integrity, and where it breaks down in a way every collector should understand. Then we run the backtest. PSA did th... | 17m 01s | ||||||
| 5/26/26 | Mangos, Messi, and Market Cap: The Hidden Math of Card Prices | Sports card investing through a Wall Street lens. Matthew Worley breaks down supply, demand, and market cap mechanics using three Messi Prizm World Cup Silvers (2014, 2018, 2022). Learn float vs pop report, gem rate math, why hypermodern oversupply breaks and vintage tightens, and how to time entry points. Data-driven card investing from Slabnomics.

| 5/5/26 | How To Read the Card Market Like a Wall Street Analyst | Seven Card Ladder charts. Three years of price and volume. Seven different cycle stages. This episode applies the Wyckoff Method, the 100-year-old framework finance uses to read market cycles, to the sports card market. The three laws. The four stages. The Composite Operator. Then chart by chart through Low-End, Mid-End, High-End, Baseball, Basketball, Football, and Soccer. By the end you'll know which segments are still early, which are running hot, which are showing distribution warni... | 26m 08s | ||||||
| 4/28/26 | The Process I Use to Find Undervalued Cards (And the 4-Month Hunt I Walked Away From) | This is the first time I've walked through the full Slabnomics process from start to finish. Post-mortem to pattern recognition to filter to hunt to execution decision. End to end, with one real trade as the worked example. I talk about: Post-mortem methodology and tag-based pattern recognitionThe four-tag rule for win-rate stackingMLD framework applied to a current superstar's valuationSupply structure analysis on Prizm World Cup Silver parallelsAlpha decay and the half-life of a... | 28m 36s | ||||||
| 4/21/26 | Why You See "Buying, 80%" (And What to Do About It) | Every Facebook card group has the post. Cash in hand. Buying at 80% of comp. Same wording, different accounts, every week. Nobody asks where the 80% came from. Today we do. This episode walks through the why of that number, the three cognitive biases that keep sellers accepting, and two practical things to do so we can stop seeing those posts. Why this practice preys on the very people we should safeguard for the long term good of The Hobby: New Entrants. Weekly Newsletter Signup: Slabnomi... | 23m 18s | ||||||
| 4/14/26 | The Discoverable Market: Why Cards Aren't Like Stocks | Both sides studied the stock market. Nobody applied this to cards. Until now. In this episode of Slabnomics, we introduce the Discoverable Market framework and make the case that the card market is neither efficient nor random. It's exploitable. The information exists. Most people just aren't using it. ✅ What the Efficient Market Hypothesis actually means ✅ The 3 conditions required for market efficiency ✅ Why collector behavioral errors aren't random The card market is newly becoming a re... | 27m 05s | ||||||

| 4/7/26 | Negotiation and How to Get Leverage in Sports Cards | Most card collectors think negotiation is just haggling: subtract from the sticker price, meet in the middle, done. It's not. In this episode, Matt breaks down the actual framework behind why deals happen and why they don't using Chris Voss's tactical empathy principles applied directly to the card market. You'll hear both sides of a real card show weekend: a buy that closed at his number and eight cards that didn't sell and why both outcomes were exactly right. Levera... | 20m 13s | ||||||
| 3/31/26 | Diving into Liquidity: 3 Types and How To Exit the Pool | This episode applies institutional liquidity frameworks to the card market. Three types of liquidity and what each one means for your portfolio. Why soccer trades like a two-buyer auction room despite 91% index gains. How price slippage destroys your comp stack when you hold multiples and list them sequentially. The difference between a market that is moving and a market that is coasting on inertia. And the exit framework that captures the middle of a move without the ego of trying to sell th... | 13m 58s | ||||||
| 3/24/26 | Financial Inertia: What Breaks the Card Market | Have you ever been right about a card and watched the market ignore you for months? This episode breaks down the hidden architecture driving card prices. Not the surface-level "supply and demand" explanation, but the actual forces underneath: the psychological biases that keep incorrect prices in place far longer than they should, the structural mechanics that used to prop up modern sets but largely don't anymore, and the specific signals that tell you when inertia is about to break (in... | 22m 44s | ||||||
| 3/17/26 | Becoming the Card Show Oracle | Most people walk into a card show with a feeling. A vague sense of what looks good, what seems reasonably priced, what a dealer's enthusiasm is worth. This episode is about the gap between walking a show with a framework and walking one with a feeling, and what that gap costs you over time. From there, the episode gets concrete. Nobel Prize-winning economist George Akerlof's "Market for Lemons" explains why card shows can be structurally inefficient. Matt walks through a rea... | 14m 45s | ||||||
| 3/10/26 | Return of the King: Topps Chrome | Topps Chrome Basketball is back, Fanatics owns the licenses to all three major American sports leagues, and the hobby is generating real noise. But this isn't a hype story. It's a supply structure event, and those play out differently than people expect. In this episode, we walk through the history of Topps Chrome refractors, the gem market cap data behind the LeBron James 2003 rookie, how Panini multiplied parallels from 11 to 80+ variations and what that did to base card values, and what it... | 21m 53s | ||||||

| 2/24/26 | I Found The Most Undervalued Cards in the Hobby | Grading has a structural mispricing that represents one of the most compelling arbitrage opportunities in the sports card market. This episode breaks down the population data, valuation multiples, and market mechanics that explain why. Key Analysis: *PSA 10 to BGS 10 Pristine population analysis using 1989 Upper Deck Ken Griffey Jr as case study *Why the 39x rarity differential only translates to 1.79x price premium (and why this is broken) *How the junk parallel era created supply fatigue ... | 13m 39s | ||||||
| 2/17/26 | Meta-tagging 311 Sales: Lessons My Sports Card Portfolio Taught Me | I analyzed every trade I made over 10 months in one of my buckets: 311 sales, $55,000 deployed and fed it all into Claude AI to find patterns. The result was a complete rebuild of how I think about sports card portfolio construction. Using meta-tags to track performance across player tier, set quality, rarity, and card type, I discovered that sets really do matter, and GOATs matter most in soccer. The finance brain wanted diversification across mid-cap players and inte... | 27m 09s | ||||||
| 2/10/26 | Prizm Comparison Across Sports | In this episode of Slabnomics, I pulled every single Panini Prizm base and silver parallel for both players: Lebron James and Lionel Messi. I compared PSA 10 populations, last sale prices, and a metric I'm calling Gem Market Cap. What I found shook me. This episode covers: How supply, demand & price discovery work differently in cards vs traditional markets The MLD Valuation Framework (Market, Legacy, Design) What "Lowest Common Denominator" analysis means for cross-player compar... | 17m 31s | ||||||
| 2/3/26 | Player Archetypes and Valuation | What makes a card valuable—not expensive, but valuable? Matt shares the questions driving his research: Can sets tell us a player's lowest common denominator? Which archetypes have the most seasonal volatility? How do sports card markets mature as alternate assets? From GOAT multipliers to post-hype sleepers, generational prospects to position-specific volatility bands—the frameworks being built behind the scenes at Slabnomics. No deep dives this week, just the questions that will defin... | 20m 45s | ||||||

| 1/13/26 | PSA 9 is Dead. All Hail Gem Mint 10 | Is the PSA 9 dead? I dove into the data across three eras (vintage, modern, ultra-modern) and four sports (baseball, basketball, football, soccer) to find out when PSA 9s hold value, and when they're just an expensive failure certificate. The numbers are staggering: PSA created 31 million new 10s since 2020, compared to just 5 million total from 1991-2019. In 2025 alone, 6.5 million new PSA 10s entered the market. When gem rates hit 60-70%, the 9 becomes meaningless. In this episode: Why v... | 24m 23s | ||||||
| 1/6/26 | A Rising Tide Does NOT Lift All Cards | The market doesn't reward truth, it rewards timing. In this episode of Slabnomics, I break down the concept of DEMAND WINDOWS and why understanding the direction of capital flow is the key to profiting in sports cards in 2026. Key insights from this episode: → Why "a rising tide lifts all boats" is WRONG for card investing → The supply absorption capacity concept explained → Sport-by-sport breakdown: Soccer, Basketball, Football, Baseball, Pokémon → Why vintage Pokémon acts like bonds in yo... | 27m 36s | ||||||

And if you're positioning like it's 2021, you're going to get hurt. I spent weeks treating the card market like an equity analyst treats a stock: pulling index data, PSA submission numbers from SEC filings, volume metrics by price tier. What I found changed how I'm positioning for 2026. In this episode: THE CORE INSIGHT, THE PSA PROOF, THE DEMAND SHIFT, CATEGORY BREAKDOWN (by sport+Pokemon), THE BILLI... | 31m 06s | ||||||
| 12/16/25 | PSA Buys Beckett/The Importance of Sets and Cycles | PSA has officially acquired Beckett, and this is more than breaking news. It’s a structural shift in the sports card market. In this episode of Slabnomics, we break down what the PSA–Beckett acquisition actually means for collectors, investors, and flippers. We zoom out to examine where we are in the market cycle, explain why this moment signals consolidation, and then zoom all the way in to the microeconomics of cards and sets...the containers that ultimately determine long-term value.
