Oct 16, 2026: Fastly falls with the software group

Fastly traded between $24.83 and $25.21 in light premarket trading, just below its $25.07 close. It opened at $24.83, touched its session high of $25.08 in the first minutes, and fell to $23.10 by 9:50am. It steadied around $23.00 to $23.60 until about 11am, then slid again, through $22.70 by 11:10am, and hit a session low of $22.32 just before 12:50pm. At 12:50pm it was $22.36, down 10.8%, on about 3.3 million shares.

What pushed it down:

  • The whole software group sold off. At 12:50pm:
Stock or fundOct 15 closeOct 16, 12:50pmChange
Twilio (TWLO)$273.40$242.23-11.4%
Fastly (FSLY)$25.07$22.36-10.8%
DigitalOcean (DOCN)$109.47$97.86-10.6%

iShares software ETF (IGV)$109.60$104.47-4.7%
Akamai (AKAM)$92.32$88.36-4.3%
  • AI financing doubts. 24/7 Wall St. reported at 11:57am that Palantir and ServiceNow each fell 5% "as investors question how trillion-dollar AI infrastructure spending gets financed," and that IGV fell about 4% against about 1% for the Nasdaq-100 fund QQQ. Yahoo Finance counted 41 of 45 stocks in its software basket falling, erasing about $130 billion of market value.
  • No Fastly news. The last 8-K was filed Aug 17. The only filings since are insider Form 4 and Form 144 notices. Chief technology officer Artur Bergman sold 37,039 shares at an average of $26.81 on Oct 12 under a prearranged 10b5-1 plan, per MarketBeat, which does not explain a drop four days later.

After the drop, RSI(14) stood at 42, the shares sat 10.5% below their 50-day average and 7.8% above their 200-day average, volume by 12:50pm was about 3.3 million shares against a 20-day average of 8.4 million, and the stock was 35.8% below its 52-week high of $34.82.

Fastly fell about as much as DigitalOcean and Twilio, which points to the sector, not the company. It fell more than Cloudflare and Akamai, its two closest rivals, which fits a smaller, more volatile stock that had just run up.

The week: from upgrade to give-back

The selloff did not start today. On Oct 9 Oppenheimer analyst Param Singh raised Fastly to Outperform from Perform with a $35 target, citing "growing contract values" as customers add security products and early revenue from AI agent traffic, per TIKR. The stock closed up 15.9% at $29.30.

On Oct 14 it fell 7.7% to $25.00 as a scare over CoreWeave's debt spread to cloud stocks. DigitalOcean fell 14.8% that day and Akamai 8.2%. KoalaGains reported that the debt fears at a peer cloud provider "triggered a sector-wide decline." We covered that scare in our CoreWeave article.

From the Oct 9 close, Fastly is down 23.7%, against 27.4% for DigitalOcean, 18.2% for Cloudflare, 17.4% for Akamai and 7.3% for IGV.

Bar chart of declines on Oct 16, 2026 by 12:50pm ET: Twilio 11.4%, Fastly 10.8%, DigitalOcean 10.6%, Okta 9.5%, Cloudflare 6.7%, IGV 4.7%, Akamai 4.3%

The numbers behind the stock

The last full update came with second-quarter results on Aug 5:

MeasureQ2 2026Q2 2025
Revenue$183.3 million$148.7 million
Security revenue$41.7 million, up 43%
GAAP gross margin63.3%54.5%
Non-GAAP operating income$27.0 million-$4.6 million
Net retention (12 months)117%
Remaining performance obligations$341 million, up 38%$247 million

Fastly guided to third-quarter revenue of $184 million to $190 million and raised its 2026 range to $732 million to $746 million. At its September investor day it set a 2029 revenue target of $1.1 billion to $1.3 billion, per StockStory. The stock rose 13.7% on Sep 23 after that event, and fell 10% the next day.

Consensus third-quarter revenue of $187.8 million, near the middle of guidance, and a price target consensus of $28.33, with a low of $23 and a high of $35. The forward P/E is 34.8 and the price-to-sales ratio at 5.2. For how to read those two multiples, see forward vs trailing P/E and the price-to-sales ratio.

The case for the stock

  • Growth sped up. Revenue growth reached 23% in the second quarter, and Oppenheimer expects high-teens to low-20s growth for the next few years.
  • Security is the engine. Security revenue grew 43%, and Oppenheimer's checks found customers adding security products to larger contracts.
  • Margins turned. Non-GAAP operating income went from a $4.6 million loss to a $27.0 million profit in a year, and GAAP gross margin rose almost nine points.
  • Nothing broke today. The drop came without a filing, a guidance change or a downgrade.

The risks

  • Valuation after a big run. The stock is up about 120% this year, and still trades near 35 times forward earnings. In a software selloff, that premium is what gets marked down first.
  • Short interest. Short sellers held 14.2% of the float, which can make swings larger in both directions. Our guide to short interest and days to cover explains how to read that figure.
  • Customer concentration. The top ten customers made up 37% of revenue in the second quarter, up from 31% a year earlier. A slowdown at one large customer would show up quickly.
  • Still losing money on a GAAP basis. The second-quarter GAAP net loss was $15.6 million.
  • Not every analyst agrees. BofA rates the stock Underperform with a $22 target and DA Davidson rates it Neutral with a $23 target, per StockStory.

What comes next

  1. Third-quarter results on Nov 4, after the close. Watch revenue against the $184 million to $190 million range, security growth, net retention against 117%, and whether the full-year range moves. Our guide to how guidance changes move stocks covers why the outlook often matters more than the quarter.
  2. The software group. Until the AI financing worry fades, Fastly is likely to trade with IGV, Cloudflare and DigitalOcean rather than on its own news.
  3. The pre-upgrade level. At $22.36 the stock sits 11.6% below its $25.29 close on Oct 8, before the Oppenheimer upgrade, and just under DA Davidson's $23 target.
