Which Piece of Speculative Fiction Had the Greatest Single-Day Stock Market Impact?
Published on 2026-02-26T18:40:00Z
Speaking of the Citrini's blog post, which imagines a near-future AI-driven economic collapse, and which ended up help triggering the S&P 500's worst single-day drop in nearly two weeks on Monday, FT Alphaville decided to track how US stock markets have moved on the release days of notable dystopian speculative fiction throughout history. The story adds: You may contend that this is facile. We would agree. You might contend that the comparisons make no sense because it's possible to read a blog post during a single work shift, but it's tricker to complete a whole novel (or sneak out to watch a movie). We would contend: do you really think traders read? Let's begin. The methodology -- tracking S&P 500 daily moves for post-1986 releases and DJIA moves for pre-1986 ones -- crowned The Matrix as the all-time leader, its March 1999 US debut coinciding with a 1.11% drop in the index. Citrini's "The 2028 Global Intelligence Crisis" came in a close second at -1.04%. On the positive end, the 2013 release of Her, a film about a man falling in love with an AI agent, coincided with the largest gain in the set at +1.66%.

Slashdot: AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks

AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks Published on July 02, 2025 at 01:30AM AT&T has launched a new Account Lock feature designed to protect customers from SIM swapping attacks. The security tool, available through the myAT&T app, prevents unauthorized changes to customer accounts including phone number transfers, SIM card changes, billing information updates, device upgrades, and modifications to authorized users. SIM swapping attacks occur when criminals obtain a victim's phone number through social engineering techniques, then intercept messages and calls to access two-factor authentication codes for sensitive accounts. The attacks have become increasingly common in recent years.

But then someone uploaded a page based on a major videogame title, according to Game Rant. And somehow this provoked a series of overreactions and missteps that eventually knocked all of itch.io offline for several hours... The page was about the first release from game developer 10:10 — their game Funko Fusion, which features characters in the style of Funko's long-running pop-culture bobbleheads.
