Bitcoin’s dominance in total market capitalization rose to 58.15%, signaling a firmer grip on overall crypto momentum. The Altcoin Index cooled to 71, a retreat from its overheated levels last week.
On September 16, Stablecoin outflows totaled $87.85M while USDC slipped $4.22M. The total stablecoin supply now sits at $248.51B.
On September 15, excluding BlackRock data, Bitcoin ETFs recorded net outflows of $5.2M and Ethereum ETFs saw $3.5M in outflows. This marks a reversal from the steady inflows seen earlier in the month and reflects a pause in institutional conviction. The upcoming Federal Reserve decision looms large as a potential driver of renewed flows either way.

According to a filing with the U.S. SEC, Polymarket included “Other Warrants” in its latest funding round. This term is often used as a reference to tokens, suggesting that Polymarket may be paving the way for a potential token issuance.
