American Tower's $55 million guidance raise is all data centers as tower revenue falls 3.3%
American Tower's Q3 2026 filing, out this morning, raises full-year property revenue guidance by $55 million and every dollar of it comes from CoreSite's data centers. The stock just rallied to a 52-week high on a SpaceX tower rumor the filing does not yet answer.

The wires will call this a steady quarter from a tower REIT. Read the 8-K filed this morning and it is a different announcement: American Tower's−1.72% — American Tower, down 1.72 percent today growth story is now its data center business, and the tower business is holding still 1. The full-year property revenue midpoint rises $55 million, attributed entirely to Data Centers outperformance; the Adjusted EBITDA midpoint, which is the tower business, was left unchanged 1.
What the filing actually says
Data center cash revenue grew 16.3% year over year, and the segment's property revenue is guided to grow about 16% for the full year, the fastest of any segment 1. Tower leasing was the missing half: organic tenant billings growth was 1.1%, and U.S. and Canada tower revenue actually fell 3.3% 1. Net income fell 14.4%, though that is mostly non-cash unrealized losses on equity investments; AFFO per share, the measure REIT investors actually use, rose 3.2% to $2.87 1.

Meanwhile management is restructuring around the split. The Board authorized an additional $2.0 billion of buybacks on October 23, and the company agreed in the quarter to sell its Canadian tower operations for about $202 million 1. That is a company shrinking its tower footprint while signaling confidence in the data center platform. It reads like someone feeding the asset AI investors want and pruning the one they don't.
Which company did you buy?
Friday's rally, and much of the 52-week high, was bought on a Bloomberg report that SpaceX is in talks for roughly 80,000 U.S. cell sites, a multibillion-dollar tenant opportunity for tower owners 2. No lease exists yet; that is a rumor about towers. The quarter that just landed shows the AI load is real, contracted and growing double digits in the data centers 1. If you own this stock for AI infrastructure, you own CoreSite wearing a tower REIT's valuation. The filing agrees with you. Friday's rally was buying a different tenant.
I think the AI buildout is the most investable story in markets, and CoreSite's interconnection-focused platform is a genuine way to hold it. But be honest about which link you own: the growth is in the data centers, and the SpaceX+2.67% — SpaceX, up 2.67 percent today tenant is still a phone call, not a contract.
