Considering the thousands of institutions researching and developing, and the large number of commercial and manufacturing enterprises now involved it would be impossible to put any finite number on it - but it is currently only a tiny fraction of what it will be when the market for Li ion batteries with graphene, graphene super capacitors, graphene strengthened steel and concrete, flexible graphene enhanced screens, graphene paints, graphene paste for 3D printing etc, etc, come on stream.
Commercial launches now announced week after week (just google graphene info).
