NiSource stock closed at USD 27.36 on the New York Stock Exchange on September 15, 2026, marking a 0.4% gain versus the prior session. Per recent trading data, the session’s volume was about 2,100,000 shares, indicating a modestly active day. NiSource’s advance contrasted with declines in major US equity indices on September 15, 2026, underlining comparatively steady performance into today’s session.

September 15, 2026 in numbers

NiSource Inc. (ISIN US65473P1057, NYSE: NI) closed at USD 27.36 on September 15, 2026, with the price sitting within its established 52-week trading band as of mid-September. The same-day trading volume of roughly 2,100,000 shares came in below a recent daily average above 2,500,000 shares, so the 0.4% rise occurred on slightly lighter turnover. Based on the latest available share count and the USD 27.36 close, NiSource’s equity market capitalization stood near USD 11,000,000,000 in mid-September 2026, according to a corporate-focused wrap by Ad-hoc-news. In the broader market, major US benchmarks such as the Dow Jones Industrial Average and the S&P 500 fell on September 16, 2026, extending the sense of volatility around utility and infrastructure names, as highlighted in a cross-market recap by KRMG, which underscores that NiSource’s earlier gain came against a backdrop of broader index weakness.

Today’s factors for NiSource stock

Into today’s US session on September 17, 2026, NiSource faces the usual sensitivity to interest-rate expectations and macroeconomic data that affect regulated utility valuations. Recent US index moves and volatility in interest-rate related assets, as described in market coverage by Etoday, suggest that broader sentiment around defensive stocks may remain important for NiSource today. Company-specific events such as the next quarterly earnings release or dividend-related dates are scheduled beyond the immediate five-day window and therefore are not central to today’s pre-market focus.
