Coinbase joins 140‑company stablecoin alliance, stock jumps 4.5%

Coinbase shares surged 4.49% to $160.49 on June 30, the day the exchange announced its participation in a 140‑company alliance backing the new Open USD (OUSD) stablecoin, a shift that could diversify its stablecoin revenue beyond Circle’s USDC [1].

Why the alliance matters

Coinbase was a founding partner of Circle’s USDC, earning a share of the interest income generated from the cash and Treasury reserves that back the token. That partnership is set to expire on Aug. 18, and the new OUSD coalition—featuring Visa, Mastercard, Stripe, BlackRock, Google and Shopify—will jointly manage the stablecoin and split its reserve earnings. By spreading reserve income across many firms, the alliance reduces Circle’s monopoly on stablecoin yields and gives Coinbase a stake in a broader stablecoin ecosystem, potentially offsetting the loss of USDC‑related revenue [1].

Potential impact on Coinbase’s financial outlook

In 2025, stablecoin‑related revenue accounted for roughly 19% of Coinbase’s $1.35 billion top line, a 48% year‑over‑year increase. Analysts project modest 4% CAGR growth in revenue and EBITDA through 2028, figures that appear weak against a 21‑times EBITDA valuation but could improve if stablecoin adoption accelerates or interest‑rate environments become more favorable. The CLARITY Act, if enacted, could further boost stablecoin yields and lessen Coinbase’s exposure to volatile crypto markets [1].

Market sentiment and ownership trends

Institutional ownership of Coinbase sits at 68.84%, with notable recent activity: Fifth Third Bancorp lifted its stake by 274% to 33,678 shares (≈$5.9 million) in Q1, while other funds such as Capital World Investors and Janus Henderson Group added sizable positions in the prior quarter [2]. Insider sales in May totaled over $5.3 million, but the stock’s 50‑day moving average sits at $171.29, suggesting the recent rally remains above short‑term trend lines [2].

What to watch

• Aug. 18 – expiration of the USDC revenue‑sharing agreement; any renewal or termination could move the stock.
• OUSD launch timeline – the date the coalition plans to issue the stablecoin; successful rollout may lift Coinbase’s stablecoin‑related earnings.
• Key price thresholds – $170 resistance (near the 50‑day average) and $140 support (close to the 12‑month low) as benchmarks for near‑term momentum.

The alliance signals Coinbase’s strategic pivot toward a more diversified stablecoin portfolio, but the ultimate effect on earnings will hinge on OUSD’s market uptake and the regulatory environment surrounding stablecoin yields.
