Polymarket targets $1 bn round, Cronos rolls back after $75 m exploit, Bitcoin ETFs see $731 m inflow

Polymarket announced plans for a $1 bn financing round that would value the prediction‑market platform at $21 bn. The round is expected to be led by 1789 Capital, which has pledged roughly $300 m, bringing its total commitment to about $500 m.

Cronos blockchain rollback

Validators on the Cronos network reverted the chain to a state prior to a Tectonic lending protocol exploit that affected approximately $75 m in assets. The rollback restored the prior ledger but raised questions about transaction finality and validator authority. RedStone clarified that the incident was not caused by an oracle failure.

Bitcoin ETF inflows

U.S. spot Bitcoin exchange‑traded funds recorded net inflows of $730.8 m on September 3, the highest daily total since January. The surge followed renewed institutional interest and coincided with Bitcoin briefly trading above $82,000 before yielding to stronger‑than‑expected U.S. employment data.
