Ex-SEC, Coinbase staffer becomes Securitize president.

Ex-SEC, Coinbase staffer becomes Securitize president. 13 hours ago Newly appointed company president Brett Redfearn briefly worked as Coinbase's head of capital markets and served for more than three years at the SEC. Cointelegraph in your social feed Tokenization platform Securitize has named Brett Redfearn as president, with the former official at the US Securities and Exchange Commission (SEC) also joining its board of directors. Securitize's Thursday notice said Redfearn previously served as the SEC's director of its Division of Trading and Markets, worked as Coinbase's head of capital markets and held various roles over a decade spent at JPMorgan. He has most recently been a member of Securitize's advisory board. Redfearn is the latest former government official to move into the crypto industry, raising questions about their roles overseeing digital assets while in office. Caroline Pham, who served as a commissioner and acting chair of the US Commodity Futures Trading Commission (CFTC), left the agency in December to join crypto payments infrastructure company MoonPay. He joins Securitize as the tokenization of real-world assets (RWA) has seen increasing demand in the crypto industry. According to data from analytics platform RWA.xyz, the company had $3.85 billion in distributed asset value in March, at a time when tokenized stocks surpassed $1 billion in total value onchain. Congress questions SEC approach to crypto enforcement cases. On Wednesday, the SEC announced that David Woodcock would become the director of its Division of Enforcement, starting on May 4, replacing acting head Sam Waldon. Several US lawmakers are calling for answers from SEC Chair Paul Atkins regarding the departure of former enforcement director Margaret Ryan. Members of Congress questioned whether Ryan left due to the SEC's decision to drop several crypto-related enforcement cases, including one against Tron founder Justin Sun.

Coinbase stock drops 55% to $174 despite 41.2% revenue growth and 36.3% free cash flow margin

Coinbase shares have declined 55% over the past six months to $174.10, prompting investors to reassess the cryptocurrency exchange platform. The company now trades at 15× forward EV/EBITDA following the drawdown. Coinbase demonstrated strong revenue momentum with a 41.2% compound annual growth rate over five years, outpacing average consumer internet companies. The firm also posted an impressive 36.3% free cash flow margin over the past two years, among the sector's highest. However, earnings per share have declined over the past four years, potentially signalling changing market trends. Despite this weakness, the company's blockchain infrastructure business continues offering trading, staking and payment solutions.

Analyst Benjamin Budish noted that global crypto trading activity has fallen to levels not seen since late 2023, despite favourable regulatory conditions. Coinbase posted a surprise quarterly loss in Q4 2025, its first since 2023, as transaction revenue fell to $982.7 million from $1.56 billion year-on-year. Consumer trading revenue dropped over 45%. The stock has declined roughly 20% year-to-date. Barclays estimates trading volumes could fall 30% quarter-on-quarter, with EBITDA tracking 24% below forecasts. The firm also questioned Coinbase's strategy to become an "everything exchange", citing limited competitive advantage.
