fomo raises $75M Series B led by Index Ventures

What happened

fomo’s blog post of 22 June 2026 says the company “closed a $75 million Series B led by Index Ventures, with strong participation from Union Square Ventures and our existing investor, Benchmark.” It also thanks eleven angel investors by name, including Zynga founder Mark Pincus and Kevin and Julia Hartz.

Adding up fomo’s own announcements gives $94 million: a $2 million pre-seed (February 2025), the $17 million Series A (November 2025) and this round. Other totals that circulate online do not match the company’s posts.

The numbers fomo gave

These are company claims, not audited figures: more than 625,000 people had joined fomo, completing over $4 billion in trading volume; more than 68,000 people had bought crypto for the first time through fomo with Apple Pay, $25 million in total.

What happened next

The round landed just before fomo’s busiest stretch. DefiLlama counts $2.48 million of fees paid to fomo in June 2026, then $7.55 million in July, $16.94 million in August and a record $35.9 million in September, before a sharp fall. Perps had launched eleven days earlier.

What we could not verify

The $550 million valuation appears in press coverage, not in fomo’s post, and we could not open the first report of it. Treat it as reported, not confirmed. The post does not name the founders. For who owns and runs fomo, see who owns fomo.
