Investors have bet big on the future of play-to-earn gaming, and they aren’t done yet.

Solana Ventures, Forte and Griffin Gaming Partners have pledged to invest $150 million in Web 3 game builders, the companies announced Tuesday.

The initiative is the second major investment Solana Ventures has made into the blockchain’s gaming ecosystem, the first being a $100 million fund co-led by FTX and Lightspeed in November.

Griffin says it has now invested over $400 million into gaming and Web 3 companies in the past two years, according to a press release.

Web 3 gaming has been a main attraction for blockchain investors in recent months, with Solana being of particular interest for its low costs and high transaction speeds.

Other sizable Web 3 gaming investments made recently include a $100 million fund led by Gala Games and C2 Ventures announced Monday, and a $200 million fund from Hashed earlier in December.

“Gaming and interactive media would not be a cornerstone of blockchain today if it weren’t for the many technical developments the community has accomplished in the past decade,” Pierre Planche, partner at Griffin Gaming Partners, said in a press release. “Solana is a premier example, having helped pave the way with scalability and [user experience] fit to match these demanding experiences.”
