Rare Bits, a crypto-collectible trading site, raises $6M Series A led by Spark Capital with First Round, Craft Ventures, SV Angel, and Justin Kan participating
Rare Bits wants to be eBay for the blockchain, where you buy, sell and trade non-fungible crypto-goods.
Context & Ripple Effects
In April 2018, Rare Bits raised a $6M Series A led by Spark Capital to position itself as the eBay of non-fungible crypto-goods — an early, generalist bet on blockchain collectibles trading before the category had mainstream vocabulary. The syndicate matters as much as the size: First Round, Craft Ventures, SV Angel, and Justin Kan all bought in.
That same investor DNA reappears later in the arc: First Round and SV Angel return for Alt's $31M Series A in sports-card collectibles, while the marketplace thesis itself fragments into brand storefronts (Bitski's $19M round), vertical niches like cricket NFTs (FanCraze's reported $100M raise), and experimental formats like Visionrare's fake-startup-share market — with Figure Markets' $60M round showing the trading-platform category still drawing capital years on.
First-order effects
- Rare Bits gets runway to build the trust-and-liquidity layer its 'eBay for the blockchain' positioning requires — search, listing, escrow-style settlement for goods whose provenance lives on-chain rather than in seller reputation.
Second-order effects
- The generalist framing gets tested almost immediately: successors split the job — Bitski builds storefront infrastructure so brands don't need a marketplace at all, and vertical players like Alt and FanCraze take collectibles categories with built-in fandoms, squeezing a horizontal crypto-eBay from both sides.
Third-order effects
- If the funding arc holds, 'marketplace for X' collapses into two surviving structures — white-label storefront rails for issuers and liquid secondary venues for traders — leaving pure intermediaries dependent on whichever side captures scarcity first.
The trend: Crypto-collectible commerce has moved from one generalist 'eBay for the blockchain' in 2018 toward specialized vertical marketplaces and brand-owned storefronts, with the same seed-stage syndicates recycling across each wave.
