2026 Topps Cosmic Chrome Baseball Checklist and Odds Guide

2026 Topps Cosmic Chrome Baseball is scheduled for November 4, and the official checklist and pack-odds sheet are now available. The new documents establish a 200-card base set, the subjects in each named insert and autograph family, and separate odds columns for Hobby and Lunar packs.

The biggest format difference is not visible from the box name alone. Several core refractors have nearly identical odds in Hobby and Lunar, but Lunar Eclipse refractors appear in the Lunar column, the published Supernova rate is much more frequent in Lunar, and the autograph rows shown on the sheet carry Hobby odds with dashes in the Lunar column.

Use this article as the detailed companion to our Cosmic Chrome product guide, baseball cards hub and Topps odds-sheet guide.

Official sources checked October 22, 2026. Topps says checklist contents and odds reflect the intended production configuration but can vary. The hero combines official Topps card previews with original CardBoard Report blueprint artwork for editorial identification; pictured cards are not store inventory.

Release date and official documents

The current Topps release calendar and Cosmic Chrome product page list Wednesday, November 4. Topps warns that release dates can change, so recheck the live page before making purchase or shipping plans.

The product page links the official 2026 Cosmic Chrome checklist and official pack odds. Match both documents to the exact year and format instead of borrowing information from an earlier Cosmic Chrome release.

What is in the 200-card base set?

The checklist runs from card 1, Shohei Ohtani, through card 200, Kyle Teel. It combines established MLB players with a substantial rookie group. Confirmed rookies include Jac Caglianone, Konnor Griffin, Roman Anthony, Munetaka Murakami, JJ Wetherholt, Chase Burns, Samuel Basallo, Bryce Eldridge and Kevin McGonigle.

That list is a starting point, not a value ranking. Build a player list from the complete manufacturer PDF, then record the card number and rookie designation before comparing singles. A player can also appear in multiple insert and autograph families with different codes.

Our checklist-reading guide explains how to separate base numbers, insert prefixes and autograph codes.

Insert families and checklist codes

The official checklist confirms these search-ready sections:

Checklist section	Code example	What to verify
Stellar Stars	SS-	Player and numbered parallel
Forces of the Diamond	FOD-	Exact subject and refractor
Dual Star Clusters	DSC-	Both subjects attached to the shared code
Triple Star Clusters	TSC-	All three subjects and team theme
Extraterrestrial Talent	ET-	Base insert versus autograph variation
Launched Into Orbit	LIO-	Subject and parallel name
Cosmic Dust	CD-	Exact player; this is a new 2026 insert
Mars Attacks MLB	MAM-	Baseball subject and crossover design
Planetary Pursuit	PPE-, PPJ- and later planet prefixes	Player plus planet level

The checklist includes 10 Planetary Pursuit subjects: Aaron Judge, Shohei Ohtani, Juan Soto, Bobby Witt Jr., Paul Skenes, Roman Anthony, Munetaka Murakami, Konnor Griffin, Kevin McGonigle and JJ Wetherholt. The same player can appear across multiple planet levels, so a title containing only “Planetary Pursuit” is incomplete identification.

Hobby versus Lunar pack odds

Topps publishes odds per pack. They are not a promise that a card will appear after opening that many packs, and they should not be presented as exact card populations.

Card family	Hobby	Lunar
Base Refractor	1:10	1:10
Nucleus Refractor	1:20	1:20
Magenta Cosmos Refractor	1:25	1:25
White Hole Refractor	1:40	1:40
Lunar Eclipse Refractor	—	1:2
Cosmic Dust	1:606	1:607
Mars Attacks MLB	1:1,513	1:1,517
Supernova	1:1,214	1:77
Cosmic Chrome Autograph Variation	1:136	—

The dash is part of Topps' sheet. It indicates that the listed row has no rate in that format column; it does not tell you how many cards were produced.

The Supernova difference is particularly important when comparing listings. A Lunar box can be the more direct route for that named insert based on the published pack rates, while a collector prioritizing the listed Cosmic Chrome Autograph Variations should study the Hobby column.

How the Planetary Pursuit ladder works

Topps lists the planet levels at progressively longer pack odds in both formats:

• Sun: 1:120
• Mercury: 1:480
• Venus: 1:720
• Earth: 1:1,200
• Mars: 1:1,680
• Jupiter: 1:4,800
• Saturn: 1:7,500
• Uranus: 1:12,000
• Neptune: 1:20,000
• Pluto: 1:28,000

Those are pack odds for finding any card at a listed level, not the odds for one particular player. Do not divide or multiply them into an individual-card population without production data that Topps has not supplied.

For a single, verify the printed card code, planet name, player and back image. Then compare the same level in completed sales. Our serial-number guide explains why numbered and unnumbered scarcity evidence should stay separate.

Autographs and format claims

The checklist contains Cosmic Chrome Autograph Variations plus other autograph families, including Extraterrestrial Talent Autograph Variations and Cosmic Dust Autographs. The odds sheet assigns Hobby rates to the autograph rows it lists and displays dashes for Lunar.

That supports a format-specific buying decision; it does not guarantee a particular autograph in one Hobby box. Use the exact odds row and box configuration when describing a chance, and never turn product-wide autograph language into a per-box promise.

A practical buying plan

Choose the format around a named target rather than the box color. Lunar has its own Eclipse refractors and a substantially different Supernova rate. Hobby is the column carrying the published autograph rates. Both formats share many base and insert odds.

For sealed offers, verify the year, format, quantity, seal photographs and total delivered cost. For singles, match the checklist code, player, refractor name and serial stamp. Chrome surfaces also deserve angled photographs for scratches, dimples and print lines; use our raw card condition guide.

The disclosed eBay searches below can include breaks, empty boxes, other years or wrongly labeled cards. Inspect the full listing. You can also browse our current shop inventory; this upcoming product is not assumed to be in stock.

Next step: download the two Topps PDFs, choose one insert or player target, and compare only listings that match the exact 2026 format and card family.
