GlobalFoundries stock gains on U.S. share sale plan and expanded AI chip deals

GlobalFoundries Inc. stock (ISIN KYG393871085) is drawing renewed investor attention after a U.S. government filing on September 18, 2026 outlined plans to sell up to 9.9 million GlobalFoundries shares, while recent AI related manufacturing deals and second quarter 2026 revenue growth underpin the fundamental story.

Government prepares to sell GlobalFoundries stake

The key catalyst for GlobalFoundries stock in mid September 2026 is a registration statement filed by the U.S. Department of Commerce to sell up to 9,907,399 ordinary GlobalFoundries shares, representing a sizeable portion of the government’s equity stake in the chip maker.Yahoo Finance reports that GlobalFoundries itself will not receive any proceeds from this sale, meaning the transaction is primarily a liquidity event for the government rather than a fresh capital raise for the company.

According to Barchart, the Commerce Department is listed as the selling shareholder and may assign or transfer shares to third parties that would in turn become selling shareholders, with detailed pricing and the exact number of shares to be sold to be set later in prospectus supplements. For investors, the scale of up to 9.9 million shares is a relevant overhang factor, but the absence of new issuance means existing share count is not directly diluted by the sale.

AI data center chip capacity deal strengthens growth narrative

Alongside the government’s planned share sale, GlobalFoundries is also benefiting from a strengthened position in AI related data center connectivity. As Ground News reported on September 17, 2026, GlobalFoundries and Marvell Technology expanded their multiyear agreement to increase production capacity for silicon germanium chips used in high speed optical connections inside data centers, with GlobalFoundries committing new capacity at its Burlington, Vermont facility.

Further detail from GuruFocus indicates that GlobalFoundries stock rose about 7 percent intraday on the day of the announcement, while Marvell Technology gained more than 5 percent, underscoring market confidence that expanded silicon germanium capacity for optical connectivity chips could accelerate both companies’ participation in AI infrastructure spending.

At the same time, Zacks notes that earnings estimates for GlobalFoundries have edged higher, with the consensus forecast for 2026 earnings per share rising 1.6 percent to USD 1.96 and 2027 estimates also up 1.6 percent to USD 2.61, while the stock carries a Zacks Rank 3 (Hold). This combination of incremental earnings upgrades and a high demand AI end market provides a constructive backdrop, even as the government’s planned sale introduces a technical risk.

Recent earnings and dividend support the case

The share sale and AI chip capacity deal build on an improving fundamental picture. According to MarketBeat, GlobalFoundries reported second quarter 2026 revenue of USD 1.79 billion and earnings per share of USD 0.46, beating consensus estimates for both metrics. That revenue level represented a meaningful step up from prior periods, and GlobalFoundries guided for third quarter 2026 earnings per share in a range of USD 0.46 to USD 0.56, signalling management’s expectation of continued profitability.

In addition, MarketBeat highlights that GlobalFoundries declared a quarterly dividend of USD 0.12 per share, implying an annualized dividend of USD 0.48 and a yield of roughly 1 percent at recent share prices.MarketBeat also notes that nine analysts currently rate GlobalFoundries stock as Buy, nine as Hold and two as Sell, with an average target price of USD 74.32. Compared with the recent trading level around the high USD 40s, this average target price points to substantial upside potential but also reflects divided analyst opinions.

Separate coverage by Traders Union emphasizes that in its Q2 2026 report GlobalFoundries delivered a 5.8 percent rise in total revenue, with its data center related segment posting a striking 62 percent increase driven by advances in photonics and silicon germanium technologies. That segment growth rate far outpaces the overall top line and illustrates how AI data center connectivity and high speed communications are becoming key drivers of the business.

Analyst consensus and valuation signals

On the valuation side, Zacks calculates that GlobalFoundries shares trade at about 18.90 times forward earnings, higher than the industry’s 13.16 forward price earnings multiple. This premium valuation suggests that the market already prices in stronger growth prospects, especially from AI related demand, and may partly explain why some analysts remain cautious despite the robust data center revenue growth.

The broader analyst picture compiled by Yahoo Finance shows that out of 22 analysts covering GlobalFoundries stock, 10 rate it Strong Buy, two rate it Moderate Buy, nine assign a Hold rating and one rates it Moderate Sell. The average price target cited in that overview is USD 77.48, implying potential upside of about 65 percent from current levels. For investors, this mix of ratings and sizable target premium highlights a classic risk reward trade off: the stock is widely viewed as a beneficiary of strategic semiconductor and AI policies, but execution and cyclicality in the chip industry remain watch points.

At the same time, CompaniesMarketCap data indicate that GlobalFoundries had a market capitalization of USD 26.65 billion as of September 18, 2026, placing it around the 909th most valuable listed company globally. The portal shows that GlobalFoundries’ market cap has increased by 33.96 percent in 2026 so far, signalling that despite volatility, investors have rewarded the company’s progress on long term contracts and strategic manufacturing capacity.

Price action, technical levels and insider activity

Recent price action reflects the interplay of these factors. MarketBeat notes that GlobalFoundries shares traded up 4.3 percent to USD 47.82 during trading hours on September 18, 2026, supported by the expanded Marvell manufacturing agreement tied to AI data center connectivity.MarketBeat describes the overall rating as Hold, meaning that while the stock enjoys solid support from part of the analyst community, it is not a consensus top pick.

From a technical perspective, Traders Union points out that GlobalFoundries shares were recently trading around USD 45.29, near their 20 day moving average, but below the 50 day moving average at USD 51.04 and the 200 day moving average at USD 53.72.Traders Union interprets this configuration as indicating short term buying interest but continued medium and long term selling pressure, with resistance identified around USD 47.41 and support at USD 45.29. For investors, those levels provide concrete reference points for assessing the stock’s momentum relative to its moving averages.

On the governance side, insider trading disclosures reveal relatively small but notable share sales. According to StockTitan, GlobalFoundries’ chief legal officer Azar Samak sold 335 ordinary shares at USD 44.87 per share on September 17, 2026 under a Rule 10b5 1 trading plan, retaining 9,464 shares after the transaction. While the total value of the sale, around USD 15,031, is small relative to the company’s market capitalization, such filings add transparency to insider activity and can be monitored alongside institutional and government stake movements.

Strategic positioning and regulatory context

GlobalFoundries’ role in evolving semiconductor policy also frames the current share sale. Barchart notes that on September 8, 2026 GlobalFoundries announced a separate agreement with the Commerce Department’s CHIPS Research and Development Office for up to USD 375 million in support to accelerate its Quantum Technology Solutions business.Barchart explains that this funding is distinct from the planned share sale and underlines the government’s broader aim to strengthen domestic chip manufacturing and advanced technology capabilities.

Coverage by Simply Wall St highlights that GlobalFoundries, with a market cap around USD 25.15 billion in its analysis, sits at the intersection of new regulatory rules, subsidy frameworks and AI hardware demand, thanks to its global network of fabrication facilities and long term chip production agreements. In that view, the company may be a key beneficiary of strategic semiconductor initiatives, even as it navigates new compliance obligations.

The company’s international expansion prospects are also in focus. As Stocktwits News relays, GlobalFoundries shares rose more than 2 percent in premarket trading after a report from Nikkei indicated that Japan and the United States are discussing a new semiconductor manufacturing project that could be operated by GlobalFoundries. The same note mentions that GlobalFoundries stock is up more than 23 percent year to date, showing that despite swings, the trend for 2026 remains positive.
