According to the source, a public social-media claim states Cantor Fitzgerald holds a 5% stake in Tether, implying a $25B value if investors assign a $500B valuation to the stablecoin issuer (source: public post on X). This claim has not been confirmed through Tether’s official communications or Cantor Fitzgerald’s newsroom at the time of writing (sources: Tether official blog and transparency page; Cantor Fitzgerald press releases). For trading, treat the headline as unverified and monitor USDT peg stability and redemption data published by Tether, along with BTC and ETH basis/funding that can reflect USDT-driven flows (sources: Tether transparency page; CME Group).
