01Sodium-Ion Batteries Energy

Batteries made from salt instead of lithium.

Sodium-ion vs Lithium-ion: Head to head Na-ion Li-ion (LFP) CELL COST ($/kWh) lower materials cost higher today in many cases ENERGY DENSITY (Wh/kg) 150-175 250-280 COLD WEATHER –20°C RETENTION 85-90% 60-70% RAW MATERIAL ABUNDANCE Na is 1,000× more abundant
Key players: CATL, BYD, HiNa Battery, Faradion/Reliance. Nearly all production is in China today.[1]
abundantsodium feedstock
China-ledearly production
bettercold-weather retention
lowerenergy density than LFP

02AI Coding Tools AI

LLMs that write, debug, and ship code. Non-programmers can now build apps from plain English.

AI coding market & the code it writes MARKET SIZE $5B 2024 $12.8B 2026 $30.1B 2032 projected AI-assisted a large share of new code now involves AI 84% devs use or plan to use AI tools 55% faster task completion with AI KEY PLAYERS: GitHub Copilot Cursor Claude Code Replit Amazon Q Dev Analysts expect AI to generate a growing share of new code, but exact estimates vary
GitHub Copilot alone has 4.7M paid subscribers and is used by 90% of Fortune 100 companies.[2]

03Next-Gen Nuclear Reactors Energy

Carbon-free baseload energy for data centers and remote towns.

Reactor comparison: traditional vs next-gen 1,000 MW Traditional 10+ yrs to build $10-25B per plant 300 MW SMR 3-5 yrs, factory-built $1-3B per unit 5 Micro Truck-transportable Remote sites & military GLOBAL LANDSCAPE 127 SMR designs 22 countries $800M U.S. DOE funding China's Linglong One (first commercial SMR) comes online in 2026. TerraPower & NuScale target 2029-2030.
SMRs use passive safety — they shut down without human intervention.[3]

04Hyperscale AI Data Centers Energy

The largest private infrastructure buildout in history.

Big Tech AI spending: the capex escalation Combined capital expenditure: Amazon + Google + Meta + Microsoft $0 $200B $400B $600B $155B 2023 $251B 2024 +62% $350B 2025 $650B 2026 4.2× in 3 yrs ⚡ U.S. data center power demand is rising fast; major forecasts point to sharp growth through 2030
75% of 2026 capex is AI infrastructure. Tech sector now outspends the entire U.S. utility industry.[4]

05Polygenic Screening Bio

Scoring IVF embryos for risk of complex diseases using thousands of genetic variants.

How polygenic screening works 🧬 IVF Embryos Multiple created 🧬 Genome Sequencing Whole genome per embryo 📊 Risk Scoring 1000s of variants analyzed ✅ Embryo Selection Lowest-risk embryo chosen SCREENS FOR: Heart disease Diabetes Schizophrenia Cancer Intelligence ⚠ Height ⚠ ⚠ Trait selection raises eugenics concerns. Many scientists say predictive value is limited in small embryo cohorts.
Cost: $2,500–$50,000 per IVF cycle. Key players: Genomic Prediction, Orchid Health, MyOme.[5]

06Personalized Gene Editing Bio

CRISPR therapies custom-built for a single patient's unique mutation.

Baby KJ: the first personalized CRISPR therapy DIAGNOSIS CPS1 deficiency Life-threatening 6 MONTHS Custom therapy designed FEB 2025 First infusion at CHOP MAR-APR 2025 Follow-up doses EARLY 2026 Walking, talking and thriving THE SCALE OF THE OPPORTUNITY 7,000 rare genetic diseases 300M patients worldwide ~$1M cost today (falling)
Next step: Phase I/II trial for 5 patients across 7 urea cycle disorder genes. FDA is creating a new approval pathway for bespoke therapies.[6]

07AI Companions AI

Millions form emotional bonds with AI. Comforting for some, dangerous for others.

Who’s forming bonds with AI? U.S. ADULTS adult adoption studies vary by source U.S. TEENS ⚠ 72% have tried AI companions  •  52% regular users  •  13% daily MARKET SIZE fast-growing category  •  rapid expansion since 2022 ⚠ 2025: Multiple lawsuits and investigations targeted AI chatbotcompanies over alleged links to teen self-harm and suicide
The U.S. Surgeon General declared loneliness a public health crisis.[7]

08Mechanistic Interpretability AI

Reverse-engineering how AI models actually think. An “MRI for AI.”

How mechanistic interpretability works INPUT “What is the Golden Gate Bridge?” AI MODEL INTERNALS 30 million features mapped ATTRIBUTION GRAPH EXPLAINED OUTPUT WHAT IT ENABLES: Detect deception Find hidden bias Pre-deploy safety check Test deceptive behavior KEY PLAYERS: Anthropic (pioneer, open-sourced tools) OpenAI (model honesty research) DeepMind
Researchers can now trace parts of model behavior in some cases. Anthropic open-sourced circuit-tracing tools in May 2025.[8]

09Genetic De-Extinction Bio

Using CRISPR and ancient DNA to bring back extinct species.

Colossal Biosciences: the de-extinction roadmap 2025 🐺 Dire Wolf pups 3 born (gene-edited) + “Woolly mice” created 2026 🦥 Thylacine proxy First reportedly born Tasmanian tiger, extinct 1936 2028 🦛 Woolly Mammoth First hybrid calves targeted 22-month elephant gestation TBD 🐦 Dodo COLOSSAL BIOSCIENCES $10B+ valuation TOTAL RAISED $550M FOUNDED BY George Church (Harvard)
These are hybrid proxies, not exact copies. Technologies developed here also help conserve currently endangered species.[9]

10Commercial Space Stations Space

The era of commercial human spaceflight infrastructure begins.

The ISS handoff: government → commercial 1998 2026 2028 2030 2033+ ISS (1998–2030) retiring Vast Haven-1 Launch early 2027 • 4 crew • $500M raised Axiom Station Modules attach to ISS first, then free-fly • $350M raised Blue Origin Orbital Reef “Mixed-use business park” in LEO NASA saves $1.5–1.8B/year by shifting to commercial stations • Market projected $16.4B by 2033
China's Tiangong station is already operational. If commercial stations aren't ready by ISS retirement, the U.S. risks a gap in LEO presence.[10]
