Within a single week, Zipline has put two very large numbers in front of the public. The first is regulatory: a draft environmental assessment (EA) the FAA published on Sept. 11, 2026, covering up to 220,000 drone deliveries a day across five Texas metropolitan areas. The second is financial: a Bloomberg report on Sept. 16 that the company is in early talks to raise roughly $1 billion at a valuation of about $20 billion. The two are not formally linked, but together they show how far the company wants to scale, and how much of that ambition still rests on a federal rule that has not been published.

What the FAA document actually covers

The draft EA, titled "Draft Environmental Assessment for Zipline International Inc. Proposed Drone Package Delivery Operations in Multiple Texas Metropolitan Areas," opened a 30-day public comment period beginning Friday, Sept. 11. Comments go to [email protected] and close Oct. 11.

Zipline already holds a Part 135 air carrier certificate and a 49 U.S.C. 44807 exemption for beyond-visual-line-of-sight (BVLOS) carriage. What it is asking for here is an amendment to its 14 CFR Part 135 operations specifications (OpSpecs). Because approving that amendment is a major federal action, it triggers review under the National Environmental Policy Act (NEPA), which is why the document exists.

The proposal breaks down by metro area in Table 2.2-1 of the EA:

  • Houston: 65 Chargers, 1,300 Dropboxes, 65,000 deliveries a day
  • San Antonio: 65 Chargers, 1,300 Dropboxes, 65,000 deliveries a day
  • Austin: 30 Chargers, 600 Dropboxes, 30,000 deliveries a day
  • Amarillo: 30 Chargers, 600 Dropboxes, 30,000 deliveries a day
  • El Paso: 30 Chargers, 600 Dropboxes, 30,000 deliveries a day

The totals are 220 Chargers, 4,400 Dropboxes, 220,000 deliveries and 660,000 transits per day, spread across 17,584 square miles. Where Chargers are installed with overlapping service areas, the document says Zipline would not exceed 1,000 total deliveries per day in the area of overlap.

The aircraft and the operating envelope

The EA describes Zipline's Platform 2 (P2) aircraft as weighing about 63 pounds including a maximum payload of 8 pounds. It cruises at about 70 mph at 330 feet above ground level, and can fly up to 20 miles between charges, so each round trip would be no greater than 20 miles. Each Charger, the ground-side hub, supports up to 72 docks, though most would have about 36.

Operations would run 24 hours a day, seven days a week, including holidays, with about 95 percent of flights scheduled between 7 a.m. and 10 p.m. The EA counts three transits per delivery: Charger to Dropbox, Dropbox to the delivery location, and Dropbox back to a Charger. That is consistent with the table, where 660,000 daily transits sit against 220,000 deliveries.

Seven times the current Texas approval

The relevant comparison is Zipline's existing authorization in the Dallas-Fort Worth area. According to DroneXL, the FAA authorization signed last December allowed 75 sites at 400 deliveries a day each, or 30,000 in total. The five-metro proposal is roughly 7.3 times that ceiling. It is also worth noting how the request is built: Houston and San Antonio are each sized at more than twice the volume of Austin, Amarillo or El Paso, and the per-city figures line up with the number of Chargers, at 1,000 deliveries a day per Charger in every metro.

A draft EA is a step in the process, not an approval. The public comment period is the point at which residents, local governments and other stakeholders can weigh in on noise, wildlife, land use and similar effects before the FAA moves toward a final determination. Nothing in the source material indicates when that determination might come.

The money: $1 billion at $20 billion, in early talks

On Sept. 16, Bloomberg reported that Zipline is seeking about $1 billion at a valuation of about $20 billion. That would be nearly triple the $7.6 billion valuation reported for January 2026. Paradigm is in talks to lead the round, and Tiger Global is considering taking part, according to the Bloomberg-sourced reporting carried by Transport Topics and DroneXL. Top existing investors include Valor Equity Partners and Sequoia Capital.

Two caveats apply. The discussions are described as early, and the figures may change. Zipline and Paradigm declined to comment, and Tiger Global did not respond, per DroneXL. Nothing here is a signed deal.

The reported context around the company is substantial. Zipline was founded in 2014 and has made nearly 3 million deliveries and flown more than 140 million miles, according to the reports. DroneXL puts total capital raised at about $2 billion. Customers named in the coverage include Chipotle, Jimmy John's and Walmart. On Aug. 17, 2026, Zipline announced a partnership with Uber that targets 1 million drone deliveries a day by the end of 2029; Uber took an undisclosed strategic stake, per DroneXL.

Set against that target, the Texas application is a stepping stone: 220,000 a day is roughly a fifth of the 1 million-a-day goal, and it would be concentrated in one state.

Part 108: the missing piece

Both stories sit under the same cloud. The FAA's proposed Part 108 BVLOS rule, the framework intended to make routine beyond-visual-line-of-sight flight standard instead of waiver by waiver, has not been published. DroneXL reports that the draft has sat at the White House regulatory office since July 10, 2026, and that its executive order deadline passed in February. DroneXL also reports that the Transportation Secretary's chief of staff said the department held the draft on purpose to allow internal debate about writing current technology into long-term regulation.

On timing, DroneXL quotes the FAA's Robert Reckert telling Commercial UAV Expo in Las Vegas this month that the rule is at the "10-yard line" and that he hopes it publishes before the calendar year is out. That is a hope from one official, not a commitment, and the rule remains unpublished.

Why It Matters

The Texas filing shows what BVLOS delivery looks like when it is planned at metropolitan scale, and it does so in a public federal document with specific numbers: chargers, docks, transits per day, altitudes, hours of operation. Those figures give communities in Houston, San Antonio, Austin, Amarillo and El Paso something concrete to evaluate before the Oct. 11 comment deadline.

It also shows that Zipline is pursuing scale through the existing route, an amended Part 135 OpSpec backed by a NEPA review, rather than waiting on Part 108. That is a practical choice given that the rule remains unpublished and its timing is uncertain. Whatever the outcome of the funding talks, an investor pricing Zipline at $20 billion is, in effect, betting that regulatory approvals of this kind keep arriving at growing volumes.

What to watch: the volume and content of public comments before Oct. 11, whether the FAA issues a final EA and OpSpec amendment, whether the Bloomberg-reported round is finalized on anything like the reported terms, and whether Part 108 is published.
