NEW YORK, June 20, 2026, 18:01 (EDT)
- Vistra closed at $163.75 in Thursday’s session, gaining 3.1%. U.S. markets were closed Friday for Juneteenth and stayed shut through the weekend.
- The stock rose around 10.6% during the holiday-shortened week as investors watched demand for power from AI data centers.
- Vistra’s stock goes ex-dividend on Monday, so buyers after that date won’t get the company’s next quarterly payout.
Vistra Corp. shares jumped for the week, ending up, with buyers sticking with power producers linked to artificial-intelligence data centers. That was despite U.S. markets being closed Friday for Juneteenth.
Vistra closed up 3.1% at $163.75 on Thursday, after hitting an intraday high of $170.34. Volume reached around 8 million shares. The stock has gained about 10.6% from last Friday’s $148.02 close in four sessions.
Timing is key here. The New York Stock Exchange set Juneteenth, June 19, as a market holiday in 2026, keeping its main session at 9:30 a.m. to 4 p.m. Eastern. That puts Thursday’s close as the last official trade until markets open again on Monday.
This week, trading stayed strong in stocks tied to steady power for big data centers. Constellation Energy added 2.6% last session. Talen Energy was up 6.4%. The SPDR S&P 500 ETF closed 0.8% higher and the Utilities Select Sector SPDR Fund rose 0.7%.
Vistra’s new spark is Helix Digital Infrastructure, the KKR-backed venture that launched last week with over $10 billion pledged. KKR, Kuwait Investment Authority, Nvidia and Vistra all put in money as founding partners. Vistra takes the role of preferred power supplier. That gets the Texas firm closer to hyperscalers, the big cloud and data-center buyers.
Helix CEO Adam Selipsky, who used to run Amazon Web Services, said big users of digital infrastructure face an “urgent need” to simplify their projects and boost capacity. Vistra CEO Jim Burke described power generation and grid connections as “critical gating factors” for ramping up AI operations. Nvidia’s Jensen Huang said demand for “AI factories” is extraordinary. Business Wire
Vistra’s first-quarter numbers are drawing focus beyond AI. The company posted net income of $1.03 billion and ongoing operations adjusted EBITDA at $1.49 billion. Adjusted EBITDA, a non-GAAP metric, takes out items like interest, taxes, and depreciation. Vistra kept its 2026 ongoing operations adjusted EBITDA forecast at $6.8 billion to $7.6 billion.
Analysts kept a mostly bullish stance heading into the break. TipRanks had Goldman Sachs’s Carly Davenport sticking with her Buy call on June 18, keeping a $209 target. Seaport Global’s Angie Storozynski bumped her target up to $230 on June 15. Morgan Stanley’s David Arcaro stuck with his Buy and left the target at $212 on June 12, citing upside from Helix.
Vistra’s stock faces a mechanical milestone Monday. The shares go ex-dividend June 22. If investors buy on or after June 22, they don’t get the next $0.2290 quarterly payout, which is set for June 30. To get the dividend, buyers have to be on record as of June 22.
The trade is volatile. Vistra’s forecast leaves out possible gains from the Cogentrix buyout and power deals with Meta — those are long-term electricity contracts — while the company said that actual performance will move with power prices, hedges and other variables. If AI spending weakens, permitting gets harder, plants break down or power prices slip, the bull case looks worse.
