https://techcrunch.com/2021/07/20/nft-market-opensea-hits-1-5-billion-valuation/ > It’s been a wild 2021 for NFT auction marketplace OpenSea. The startup was exceedingly well-positioned in a niche space when NFTs exploded earlier this year seemingly out of nowhere. Since then, the startup has found its user base expanding, the total volume of sales skyrocketing and more investor dollars being thrown at them. > The startup announced in March, it had closed a $23 million Series A, and now some four months later, the company tells TechCrunch it has raised another $100 million in a Series B round led by Andreessen Horowitz at a $1.5 billion valuation. Other investors in the round include Coatue, CAA, Michael Ovitz, Kevin Hartz, Kevin Durant and Ashton Kutcher.
