What Is Alt (alt.xyz)?

Alt (branded alt.xyz) is a trading card platform launched in March 2021 by Leore Avidar, who previously founded the mailing-API company Lob, with backing that included Reddit cofounder Alexis Ohanian's Seven Seven Six. Alt combines three pieces most collectors otherwise juggle separately: a vault for insured, climate-controlled storage; an auction and fixed-price marketplace for buying and selling vaulted cards without shipping; and a lending arm that lets an owner borrow against a card's value instead of selling it outright. Every vaulted card gets an "Alt Value" — Alt's own estimate of what the card is worth — and that number is what the marketplace pricing tools and the lending program are both built around.

• Graded cards vault free above a value floor. Cards graded by PSA, BGS, SGC, or CSG store for free once their Alt Value clears Alt's minimum threshold; lower-value graded cards and raw cards can still be stored but carry an intake fee.
• Only graded cards are marketplace-eligible.A raw card can sit in the vault, but it can't be listed for sale on Alt until it comes back from grading — the marketplace only lists cards from the supported graders above.
• Withdraw anytime.As with any vaulting model, a stored card isn't locked in permanently; requesting physical delivery ships it out and ends its marketplace eligibility until it's sent back.

The feature that sets Alt apart from a plain vault-and-marketplace setup is that a vaulted card can be turned into cash without selling it. Consigning an eligible card — generally one with an Alt Value of $250 or more — for a cash advance gets an offer of up to roughly 70% of that valuation paid out within about a business day, with the remainder following (minus a fee) once the card actually sells. Separately, Alt runs a portfolio-loan program that lets an owner borrow against a whole collection of vaulted cards — loan sizes have ranged from the tens of thousands into seven figures — backed by outside credit facilities (Alt disclosed a $40 million asset-based facility from Trinity Capital). Both programs work the same way conceptually: the card or portfolio stays in Alt's vault as collateral instead of shipping to a buyer, and the loan or advance is sized off the Alt Value, not a fixed price the owner sets.

eBay Vault and Arena Club both let a vaulted card change hands without shipping, and Arena Club adds its own in-house grading on top. Alt's vault and marketplace work on the same underlying idea, but neither eBay Vault nor Arena Club offers a built-in way to borrow cash against a stored card — on those platforms, turning a vaulted card into money means selling it. Alt's cash-advance and portfolio-loan programs are the differentiator: they let an owner raise cash from a collection while keeping ownership, closer to a securities-backed line of credit than a straight sale.

• Alt Value is Alt's own estimate.It drives both the advance amount and loan sizing, so it's worth comparing against recent comps elsewhere before treating it as a firm resale price.
• Advances and loans aren't free money. A cash advance is paid against a future sale, and the remainder is reduced by a fee once the card sells; a portfolio loan is debt collateralized by the vaulted cards, not a payout.
• Liquidity is platform-bound.Selling fastest means selling to another Alt user on Alt's marketplace; moving a card off-platform means withdrawing it and shipping first, same as any vaulting service.
• Terms change.Advance percentages, minimum Alt Values, and eligible graders have shifted since launch — confirm current terms directly on alt.xyz before consigning or borrowing.
