According to the source, a market-cap flip between BNB and Tether (USDT) is being reported; traders should verify live rankings on CoinMarketCap and CoinGecko before acting. source: CoinMarketCap, CoinGecko To confirm, compare BNB’s market cap computed as price times circulating supply with USDT’s circulating supply reported on Tether’s transparency page, since market capitalization equals circulating float multiplied by last traded price. source: CoinMarketCap, Tether Transparency If confirmed, BNB would move above USDT in the global ranking behind BTC and ETH, which can increase BNB’s weight in market-cap-weighted crypto indices at the next scheduled rebalance, potentially affecting passive allocation flows. source: Bitwise Crypto Index Methodology, FTSE Russell Digital Asset Indexes Methodology For trading, monitor BNB spot depth and derivatives funding rates across major venues to gauge momentum, while tracking USDT issuance or redemptions that can quickly alter relative market caps. source: Binance Markets Data, Tether Transparency Risk note: intraday rank changes can revert as prices and stablecoin supply update continuously, so confirm across multiple aggregators before executing size. source: CoinMarketCap, CoinGecko

According to the source, BNB would surpass USDT’s market cap at a price of $1,236 (source: X post dated Sep 21, 2025). The flip threshold equals USDT circulating market cap divided by BNB circulating supply; traders can verify by pulling USDT’s latest circulating market cap from Tether’s Transparency page and BNB’s circulating supply from BNB Chain’s BNB Auto-Burn portal or BscScan, then applying Threshold Price = USDT Market Cap / BNB Supply (sources: Investopedia market capitalization definition; Tether Transparency; BNB Chain BNB Auto-Burn; BscScan BNB supply). If verified, a BNB-over-USDT flip would change market-cap rankings used by market-cap-weighted digital asset indices, affecting constituent weights and potential passive flows (source: S&P Dow Jones Indices Digital Market Indices methodology).
