Constellation Energy fell 5.09% to $280.74 following news that Google signed a deal for existing reactors rather than new capacity from advanced nuclear developers. Per Motley Fool, the announcement—which benefited competitors Oklo and NuScale—highlighted that Google's near-term power needs are being met through existing infrastructure, potentially limiting near-term growth opportunities for CEG's new reactor projects. Volume of 1.06M shares is tracking 0.79x normal for this point in the trading day.
Constellation Energy (CEG) rose 5.23% to $299.99, extending a multi-day rally driven by a landmark 20-year nuclear power supply agreement with Google announced October 6, 2026, which includes 890 MW of uprates across 11 reactors in Illinois, Pennsylvania, and New Jersey plus a separate 2,700 MW supply deal. The rally follows a similar Amazon agreement signed in late September and management's recent guidance raise to $11.50–$12.50 adjusted EPS per share. Volume at 2.07 million shares is running at 0.83x normal for this stage of the session.
Constellation Energy fell 5.28% to $283.78, reversing recent gains despite positive nuclear deal momentum. The stock had surged 12.3% in the prior session following announcements of major contracts with Google and other Big Tech firms (890 MW capacity addition, $4.3B in upgrades), but intraday selling pressure emerged today at above-average volume (1.54x normal for this time of session). The pullback suggests profit-taking after the recent rally.
Constellation Energy announced a 20-year power supply agreement with Google, driving a +11.47% intraday rally to $298.31 (from $267.62). The Investopedia report confirms the deal as the primary driver. Volume surged to 9.7M shares, 4.08x the time-adjusted expected level, reflecting strong investor interest in the long-term contracted revenue.
Constellation Energy rose 3.25% to $262.28 on elevated volume (3.13x average for the time of day), following a 247wallst.com report citing a Wall Street analyst projecting 75% gains ahead for the stock. The move reflects broad bullish sentiment on CEG's 2026 performance, though no company-specific catalyst or news event was announced today.
Constellation Energy fell 5.92% to $248.91 on September 30, 2026, as rising Treasury yields and broad profit-taking pressured rate-sensitive utility and clean-energy sectors. The 10-year yield's persistence has increased borrowing costs and reduced appeal of high-valuation nuclear and AI-linked power infrastructure plays, triggering sector-wide rotation away from recent winners.
CEG fell 2.11% to $257.25 as part of a multi-day downward slide affecting rate-sensitive utilities and clean-energy infrastructure names, driven by recent interest rate adjustments, elevated Treasury yields, and equity overhang concerns following major portfolio adjustments including acquisitions like the Rhode Island State Energy Center (per finance.yahoo.com). The stock is down sharply on sector-wide profit-taking and valuation friction on high-multiple energy-transition names.
Constellation Energy rose 2.06% to $290.92, driven by today's dividend payment date (September 4, 2026 — $0.4265/share) and sustained investor demand for nuclear-backed clean energy exposure amid AI and data center growth (per web_catalyst and Yahoo Finance sources). Volume of 531,507 shares is tracking 0.87x normal for this time of day.
